The area between the garage doors and the driveway has a 1" gap. The

More likely the ground under the driveway has settled and pulled back from the
garage.

How do I fill this gap?

Why do you have to? In the grand scheme of things it isn't harming anything and
you are probably the only one who notices it.

To keep cold air out? The better sheltered it was during the night,
the better the car will start in the morning.

Plus, if you close up the gap, you'll reduce the number of critters
that come inside to take up residence. Notice I said "reduce":
complete interdiction is probably not achievable.
