ABSTRACT:
The technique of the invention sets a relationship between the throttle opening (corresponding to the accelerator opening), the vehicle speed, and the target torque of a drive shaft, so as to enable a greater braking torque to be output in a working status of a cruise control system than a braking torque, which is output to the drive shaft in a full closed position of the accelerator opening in a non-working status of the cruise control system. This arrangement ensures output of a sufficient braking force to the drive shaft even under the condition of a relatively large drive load applied to the drive shaft, for example, during a downslope run, thus enabling the vehicle speed to be certainly kept at a preset level under the control of the cruise control system.
