VEHICLE RUNNING CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To selectively execute the constant speed running control or inter-car distance control using a vehicle running control device and eliminate any complicated switch operation at resuming the car speed control including the both controls. SOLUTION: When a judging part 20 judges that the requisite conditions for car speed control are met in association with stamping of an accel. pedal, a target car speed setting part 30 selects either of the constant speed running target car speed Vctar equal to the previous constant speed running target car speed or the follow-up target car speed Vfol determined from the actual inter-car distance Lact whichever is the smallest and sets the selected value as the target car speed Vtar. In conformity to a car speed control execute instruction given by a car speed control instruction part 40, a car speed control part 50 controls a throttle actuator 60 so that the constant speed running or a pursuit run is conducted at the target car speed.
