Abstract
When a vehicle-to-vehicle time gap is changed from a first level to a second level with a selector switch, a controller determines a desired time gap so that the desired time gap varies from the first level to the second level at such a gradual rate as to prevent an abrupt change in the vehicle speed. The controller further determines a desired vehicle spacing from the controlled vehicle to a preceding vehicle in accordance with the desired time gap and a sensed vehicle speed, and controls the driving force and braking force of the controlled vehicle so as to bring the actual vehicle spacing closer to the desired vehicle spacing.
