Abstract
In a vehicle running control apparatus and method, the change of a difference in frequency between an electromagnetic wave signal transmitted from a vehicle and an electromagnetic wave signal reflected from an object is detected. Information inclusive of a distance between the object and the vehicle and a relative speed of one of the object and the vehicle to the other is generated on the basis of the change in frequency difference. A desired speed is generated on the basis of the generated information and information of the running of the vehicle so that the change in frequency difference is generated. A signal for control of the speed of the vehicle is generated on the basis of the desired speed.
