ABSTRACT:
A running state control system for a motor vehicle comprises engine output torque control means, shift detecting means, and a valve timing control system (VTC). When detecting a shifting, the shift detecting means outputs a torque cutoff command signal to the engine output torque control means so as to actuate the valve timing control system. An opening timing of intake valves is changed thereby in a direction such to decrease an engine output torque. In another aspect of the invention control is exercised over a braking torque applied to the driving wheels of the vehicle in correspondence with a traction loss or skid detected thereat.
