Device for controlling engine intake throttle for turn stability control of vehicle

摘要

A device for controlling intake throttle of an engine of a vehicle having: a means for estimating an instability quantity representative of turning instability of the vehicle; a means for estimating lateral acceleration of the vehicle; a means for estimating friction coefficient of road surface; a means for estimating a brake limit of a pair of drive wheels based upon the lateral acceleration and the road surface friction coefficient; a means for estimating an engine brake torque limit based upon the brake limit of the pair of drive wheels of the vehicle and the instability quantity; a means for estimating a target intake throttle value corresponding to the engine brake torque limit; and a means for attenuating intake throttling of the engine to the target intake throttle value when the intake throttling is tighter than the target intake throttle value.
