If i were to guess it would be this:

Newtons first law states that a body will remain at a constant speed and remain in a straight line unless acted upon by a resultant force.

Now, with auto braking, I think it just means that the car/wheels will carry on going at a constant speed. Now when you apply the brakes the disk brakes use brake pads which make contact with the rotor (the thing causing the wheels to rotate). This causes friction and slows down the rotation and hence lowers the speed of the car until the speed is 0. Here the friction is the resultant force.
