Brakes seizing on electric cars?

"Michael Chare" wrote in message ... I've heard that it takes a second or so to apply and release the handbrake. This makes it very difficult to hold the car on the handbrake briefly while "changing feet" to do a hill start on an uphill gradient. I am used to coordinating hand and feet movements: 1) apply handbrake, 2) move foot from footbrake to accelerator, 3) bring clutch up to bite point and apply power, 4) release handbrake, increase power and let clutch up. It sounds a right Too many steps to that procedure, IMHO. As a kid, I learned to do it without the handbrake steps. Like you said, after a bit it becomes second nature and you do it without having the car roll back. I remember watching Greyhound bust drivers doing that 55 years ago, the did roll back a little. I keep my toe on the foot brake and use my heel to press the accelerator. I learned to drive on my mum's little Renault and that had such a small petrol engine that if you brought the clutch up to the bite point so the car didn't roll back, the engine would stall with no accelerator (ie until I'd moved my foot from the footbrake to the accelerator). So I got into the habit of always using the handbrake to hold the car during that time, as I was taught for the driving test, and I still do it even in modern diesel cars which have enough torque to allow the clutch to slip and hold the car stationary, with no throttle. I've never had a car that would do that, even a 1 litre petrol. Maybe I have more agile feet. If you move your feet quicker, you don't need so much non-throttle power. I soon dropped some of the other pedantic things that the driving test teaches you, like applying the handbrake after every forward and backward cycle of a three-point turn, Wow, I don't remember being told to do that when I took my test in 1997. Maybe they stopped it. That would take ages!! and changing down through every gear when braking to a halt. I don't recall having to do that either. I think I was told to change down SOME gears, but not every one, and definitely not into 1st, that would cause a jerk. When I took my advanced test about 10 years after the normal test, *not* changing down gear-by-gear was normal IAM practice - and that's what I do nowadays: brake almost to a halt in 6th gear I do that, but am probably wearing out the brakes. I'm talking about planned stopping for a roundabout, not an emergency. Mind you, I'm also not wearing out the gears and clutch. and then go straight into whatever gear I need to accelerate out of the hazard once I see whether or not I need to stop completely at the give-way line. I gather that the normal test has now abandoned the change-down-through-every-gear advice. My nephews were saying that they were told not to change down at all when going down a steep hill, but to rely *only* on the brakes, without the assistance of engine braking. I'm talking about a long 1:3 hill, not every puny 1:100 slight slope. Bad idea if it's a lot of slope. I think I've only used gears on a hill once though, in the French alps. It was when the brakes started smelling hot. I was descending a winding road at about 10mph (sharp corners) to 30mph (the straight bits), the hill continued for at least 10 minutes. So I dropped into the manual equivalent of 3rd and sometimes 2nd (it was an auto so 2nd and 1st) to limit the speed to something more reasonable, then used the brakes to adjust the speed for each corner. One useful trick that my IAM "observer" (instructor) taught me was to get into the habit of always waggling the gear lever from side to side just before starting the engine or turning it off. If the car is in gear, the lever won't move and I'll know that I have to put it in neutral (or press the clutch) before starting, and I'll know I can't just let the clutch up blindly after stopping and as I'm about to turn off. Saves the embarrassing (and maybe costly) mistake of the car unexpectedly lurching forward. Completely unnecessary, just start the car with the clutch pedal pushed in. |

Maybe they stopped it. That would take ages!! I never heard of that and did not have to practice it or do it for the drivers test back in 1966. We had several weeks of drivers ed and it was with a manual transmission. The car I took my test in was an automatic. Maybe it's different in the US, but in the UK if you pass your test in an auto, you can't legally drive a manual. We did have to give hand signals,however it was cold when I took the test and the lady giving the test told me she was not feeling well and I could use the electricl signals. You would have had to use hand signals in a car with electrical ones? What purpose would that serve? Then you'd have passed your test unable to use newer cars. |

In the US the type of transmission for the test does not matter. Kinda insane, since if you've never driven a manual, you're gonna be a bit dangerous. IN NC there is a seperate test for motocycles now. However for anything under so many thousand pounds other than the motocycle it is just one license no mater what you take the test in. Above that I think you get into the comercial license that lets you drive the tractor tralier type rigs. There's some funny rules here about weight. If I hire a van and put more than a certain amount in the back, technically I'm breaking the law. I think. The three wheel bikes (usually clled a trike) just need the regular drivers license. Told you the hand signals were a thing back in 1966. Lots of cars on the road back then did not have electrical turn signals. So the test should have covered both. |

More likely the driver would overtake closer than the legal 1.5m distance and knock it off themselves. If you're wobbling by 1.5m in each direction, you need to take a cycling proficiency test. I cycle on the road, and I'm quite happy for cars to leave 1 cubit between me and them. Do you seriously expect a queue of 10 cars stuck behind you to wait until nothing is coming the other way?

I learned to drive on my mum's little Renault and that had such a small petrol engine that if you brought the clutch up to the bite point so the car didn't roll back, the engine would stall with no accelerator (ie until I'd moved my foot from the footbrake to the accelerator). So I got into the habit of always using the handbrake to hold the car during that time, as I was taught for the driving test, and I still do it even in modern diesel cars which have enough torque to allow the clutch to slip and hold the car stationary, with no throttle. I've never had a car that would do that, even a 1 litre petrol. Maybe I have more agile feet. If you move your feet quicker, you don't need so much non-throttle power. I soon dropped some of the other pedantic things that the driving test teaches you, like applying the handbrake after every forward and backward cycle of a three-point turn, Wow, I don't remember being told to do that when I took my test in 1997. Maybe they stopped it. That would take ages!! and changing down through every gear when braking to a halt. I don't recall having to do that either. I think I was told to change down SOME gears, but not every one, and definitely not into 1st, that would cause a jerk. When I took my advanced test about 10 years after the normal test, *not* changing down gear-by-gear was normal IAM practice - and that's what I do nowadays: brake almost to a halt in 6th gear I do that, but am probably wearing out the brakes. I'm talking about planned stopping for a roundabout, not an emergency. Mind you, I'm also not wearing out the gears and clutch. and then go straight into whatever gear I need to accelerate out of the hazard once I see whether or not I need to stop completely at the give-way line. I gather that the normal test has now abandoned the change-down-through-every-gear advice. My nephews were saying that they were told not to change down at all when going down a steep hill, but to rely *only* on the brakes, without the assistance of engine braking. I'm talking about a long 1:3 hill, not every puny 1:100 slight slope. Bad idea if it's a lot of slope. I think I've only used gears on a hill once though, in the French alps. It was when the brakes started smelling hot. I was descending a winding road at about 10mph (sharp corners) to 30mph (the straight bits), the hill continued for at least 10 minutes. So I dropped into the manual equivalent of 3rd and sometimes 2nd (it was an auto so 2nd and 1st) to limit the speed to something more reasonable, then used the brakes to adjust the speed for each corner. If the indicator had 2 and 3 on it, then, rest assured, there was a 1st below that but it just didn't have a *lock* control on it so no indicator at the selector. It had 123DNRP. I call it "2nd" instead of the "1" marked on it, as it had 4 gears, roughly lined up with a manual's 2/3/4/5. That is all those numbers indicate - the ability to lock into either 2nd or 3rd without the trans doing auto upshifts. This was a 1998 car, not one of those old mechanical gearshifts. All the lever did was electronically request the gear you prefer. If I selected 1st at 100mph, nothing happened. If I selected 1st at 60, it would drop to 3, then as the car slowed, 2, then eventually 1. I tried it once at high speed and alarmed a passenger who'd never seen an auto before. The car very neatly slowed down rapidly, dropping gears at precisely the right time to make the revs just touch the red line. Accelerating with it in 3 would keep it in 3 until it was bad to do so, as in overrevving, then go into 4th. |

Preventing any gear change at all. Starting off in a high gear could be useful on ice, etc. Every auto I've driven (3 of them) was perfectly good in ice and snow using D. Press the gas gently and it would stay in the highest gear possible. One of them (a 1988 3.5L V8 4WD Range Rover) didn't have so many safety measures on it. I could rev it up fully in N, then select D. All 4 wheels spun briefly and the vehicle shot forwards. Scared the **** out of any nearby pedestrians. |

More likely the driver would overtake closer than the legal 1.5m distance and knock it off themselves. If you're wobbling by 1.5m in each direction, you need to take a cycling proficiency test. I cycle on the road, and I'm quite happy for cars to leave 1 cubit between me and them. Do you seriously expect a queue of 10 cars stuck behind you to wait until nothing is coming the other way? You're as bad as a caravaner. I am happy to sit behind a horse rider until I can overtake them on the opposite side of the road, as I also am for a cyclist. A horse gets spooked, a cyclist does not. After all, I spend more time in traffic jams behind cars than waiting to overtake cyclists safely. I'm not talking about traffic jams, I'm talking about when the road has plenty of room to go at full speed, but there's something like a tractor or caravan going too slowly, but too much coming the other way to overtake it. Why the **** don't they pull into laybys?! As for cyclists, there's loads of room for 2 cars and a bicycle on most roads, so you can overtake with oncoming traffic. If they're too far out (like your sort) they soon move in when you threaten to nudge them. |

Troll-feeding Senile AUSTRALIAN ASSHOLE Alert!
On 11 Aug 2020 01:21:50 GMT, Beno, another brainless, troll-feeding,
senile Australian idiot, blathered: You cannot arbitrarily assign your own numbering system to the ratios. He CAN! He's clinically insane, you demented, troll-feeding, senile asshole! Some examples of Birdbrain Macaw's (now "James Wilkinson" LOL) sociopathic "mathematics": "100 is 5 times more than 20. "5 times less" is the opposite of "5 times more", so this makes 100 back to 20 again. 20 is 5 times less than 100, the same as dividing by 5. An elephant is 5 times bigger than a tiger, a tiger is 5 times smaller than an elephant." MID: ---------------------------------------------------------------------------------------------------------- "I'm comparing being able to tell the difference between 21 and 12 to being able to tell the difference between 21 and 12. If you think that it's easy to think a 12 year old is 21, it's only fair to use it as a reason when you get caught ****ing a 12 year old, which you mistook to be 21." MID: ---------------------------------------------------------------------------------------------------------- "50 watts is ten times more than 5 watts. Likewise 5 watts is ten times less than 50 watts." MID: ---------------------------------------------------------------------------------------------------------- "The answer is 9. The 0.5 chicken is dead, so basically it's 1 chicken laying 1 egg per day. The half egg was one halfway out, the only egg for that day." MID: ----------------------------------------------------------------------------------------------------------- "let's say you prefer 20C water. If you go in 10C water you'd say that was cold (10C colder than you want). Now you go in 0C water, that's twice as cold, because it's now 20C colder than you want." MID: ------------------------------------------------------------------------------------------------------------ "Even if only 25% of people want it legalised, and let's say LibDems already have 15% of the vote. If 75% of that 15% stop voting for them because they don't want it legalised, they're down to 3.75%. But 25% of the 85% who didn't previously vote for them, change their mind due to this policy, they gain 21.25%, giving them a total of 25%, well up from 15%." MID: -------------------------------------------------------------------------------------------------------------- "If I say 1, then "or so", the "or so" means another 1. If I say 5, then "or so", the "or so" means up to another 5. Is English not your first language?" MID: ---------------------------------------------------------------------------------------------------------------- "If you live for 4 years and die, you wasted 4 years. If you live for 20 years and die, you wasted 20 years, that's 5 times worse." MID: |

If 1 is the lowest ratio, then it is 1 not 2 or any other notation you might dream up. I see it went right over your head. Let me try to explain simply for you. In a manual, the gears are approximately equal ratios - eg 2nd is twice 1st, 3rd is three times first, etc. In an auto, it's the 1st that's missing. They may be called 1234 by the manufacturer to make it simpler for the driver, but that's not what they are. The 1, 2 & 3 indications on the shift indicator are Lock Ratios indicating the trans wont upshift beyond that ratio. Wrong, it will to avoid overrevving.

It matters a lot what the mechanism is. If it's mechanical, it's no longer overrideable by the computer. The difference here is the electronics are much more adept in the foolproofing department - as you clearly make apparent. Nothing to do with foolproofing, it's making it easier to use. I want the car to slow rapidly in an emergency without having to select 3 2 1 in order, just select 1 and let the car sort the gears while you concentrate on braking and steering to avoid what you might be going to hit. |

So I got into the habit of always using the handbrake to hold the car during that time, as I was taught for the driving test, and I still do it even in modern diesel cars which have enough torque to allow the clutch to slip and hold the car stationary, with no throttle. I've never had a car that would do that, even a 1 litre petrol. Maybe I have more agile feet.Â* If you move your feet quicker, you don't need so much non-throttle power. I soon dropped some of the other pedantic things that the driving test teaches you, like applying the handbrake after every forward and backward cycle of a three-point turn, Wow, I don't remember being told to do that when I took my test in 1997.Â* Maybe they stopped it.Â* That would take ages!! and changing down through every gear when braking to a halt. I don't recall having to do that either.Â* I think I was told to change down SOME gears, but not every one, and definitely not into 1st, that would cause a jerk. When I took my advanced test about 10 years after the normal test, *not* changing down gear-by-gear was normal IAM practice - and that's what I do nowadays: brake almost to a halt in 6th gear I do that, but am probably wearing out the brakes.Â* I'm talking about planned stopping for a roundabout, not an emergency.Â* Mind you, I'm also not wearing out the gears and clutch. and then go straight into whatever gear I need to accelerate out of the hazard once I see whether or not I need to stop completely at the give-way line. I gather that the normal test has now abandoned the change-down-through-every-gear advice. My nephews were saying that they were told not to change down at all when going down a steep hill, but to rely *only* on the brakes, without the assistance of engine braking. I'm talking about a long 1:3 hill, not every puny 1:100 slight slope. Bad idea if it's a lot of slope.Â* I think I've only used gears on a hill once though, in the French alps.Â* It was when the brakes started smelling hot.Â* I was descending a winding road at about 10mph (sharp corners) to 30mph (the straight bits), the hill continued for at least 10 minutes.Â* So I dropped into the manual equivalent of 3rd and sometimes 2nd (it was an auto so 2nd and 1st)Â* to limit the speed to something more reasonable, then used the brakes to adjust the speed for each corner. If the indicator had 2 and 3 on it, then, rest assured, there was a 1st below that but it just didn't have a *lock* control on it so no indicator at the selector. It had 123DNRP.Â* I call it "2nd" instead of the "1" marked on it, as it had 4 gears, roughly lined up with a manual's 2/3/4/5. You cannot arbitrarily assign your own numbering system to the ratios. If 1 is the lowest ratio, then it is 1 not 2 or any other notation you might dream up. I see it went right over your head.Â* Let me try to explain simply for you.Â* In a manual, the gears are approximately equal ratios - eg 2nd is twice 1st, 3rd is three times first, etc.Â* In an auto, it's the 1st that's missing.Â* They may be called 1234 by the manufacturer to make it simpler for the driver, but that's not what they are. It has become quite clear to me that all this is going right over *your* head. Your idea that gears are approximately equal ratios is wrong. The gear ratios are selected at the design stage to suit the torque and power curves of the engine countered by the mass of the vehicle. Get this, the torque converter does not endow an auto with a magical low gear. It simply multiplies torque through a regenerative process. It does this at any time the engine is under power acceleration and in any and every gear. The 1, 2 & 3 indications on the shift indicator are Lock Ratios indicating the trans wont upshift beyond that ratio. Wrong, it will to avoid overrevving.Â* Again, what you select with the lever is simply a suggestion to the car's computer. Like I've said, that is but an attempt to make the trans foolproof. I have noted, however, fools are very ingenious and can wreck anything they turn their hands to. A lock is not required on 4th which is, should you care to investigate, an overdrive ratio. The direct drive (1:1) is usually on 3rd in a 4 speed auto. As well, the trans is likely set up so TC lockup is only enabled on overdrive 4th. A lock on 4th would be handy if you wanted to drive more economically. Not at all. You would be surprised at the number of people out there who fail miserably to understand the concept of economical driving. You have indicated by your response above that you are one such person. But then you can always just use a lighter foot. It ain't that simple. That is all those numbers indicate - the ability to lock into either 2nd or 3rd without the trans doing auto upshifts. This was a 1998 car, not one of those old mechanical gearshifts.Â* All the lever did was electronically request the gear you prefer.Â* If I selected 1st at 100mph, nothing happened.Â* If I selected 1st at 60, it would drop to 3, then as the car slowed, 2, then eventually 1.Â* I tried it once at high speed and alarmed a passenger who'd never seen an auto before.Â* The car very neatly slowed down rapidly, dropping gears at precisely the right time to make the revs just touch the red line.Â* Accelerating with it in 3 would keep it in 3 until it was bad to do so, as in overrevving, then go into 4th. It matters not one whit what the selection mechanism is. It matters a lot what the mechanism is.Â* If it's mechanical, it's no longer overrideable by the computer. The difference here is the electronics are much more adept in the foolproofing department - as you clearly make apparent. Nothing to do with foolproofing, it's making it easier to use.Â* I want the car to slow rapidly in an emergency without having to select 3 2 1 in order, just select 1 and let the car sort the gears while you concentrate on braking and steering to avoid what you might be going to hit. If you drive in a manner that would cause you to require first whilst at a speed where you are rolling along in 4th, I'd suggest it might be time to hand in your driver's licence. -- Xeno Nothing astonishes Noddy so much as common sense and plain dealing.
