Gesamtsteuerungssystem für eine Fahrdynamikregelung und CVT-Getriebe in einem Kraftfahrzeug

摘要

A vehicle includes a continuously variable transmission whose gear ratio can be steplessly changed and a posture control apparatus that controls vehicle posture in a yaw direction during cornering by controlling output of the engine and the braking forces. When understeer of a preset extent or greater is detected for the vehicle during cornering, the vehicle driving torque is reduced by controlling a reduction in the engine output and by controlling the gear ratio of continuously variable transmission so as to suppress the change in vehicle driving torque that accompanies the controlled reduction in engine output. As a result, understeer can be favorably avoided.
