Abstract
A motor torque control system for a vehicle equipped with a drive torque generating motor is comprised of a vehicle speed detector, an accelerator opening detector, a brake depression detector and a control unit. The control unit rapidly brings a motor torque to zero when a vehicle speed is lower than a predetermined speed, when an accelerator opening is substantially zero, and when a brake depression quantity is increasing, and generates the motor torque according to the brake depression quantity when the brake depression quantity is deceasing.
