Abstract
An automatically driven motor vehicle is controlled to automatically follow a front motor vehicle while controlling an intervehicular distance up to the front motor vehicle. A speed of the motor vehicle and an intervehicular distance up to the front motor vehicle are recognized, and acceleration/deceleration correcting data for the motor vehicle to adjust the recognized intervehicular distance depending on the recognized speed of the motor vehicle are generated. The acceleration/deceleration correcting data are generated based on a first correlation determined between the speed of the motor vehicle and the intervehicular distance such that the intervehicular distance increases as the speed of the motor vehicle increases when the speed of the following motor vehicle is greater than a predetermined speed. The acceleration/deceleration correcting data are generated based on a second correlation determined between the speed of the following motor vehicle and the intervehicular distance such that the intervehicular distance increases at a rate smaller than the first correlation as the speed of the following motor vehicle increases when the speed of the following motor vehicle is smaller than the predetermined speed. Acceleration and deceleration of the motor vehicle are controlled depending on the acceleration/deceleration correcting data.
