Control system for electric vehicle
In an electric vehicle including a transmission provided between a motor and driven wheels, if a shift change detecting means has detected the shift change from a "D" range or an "R" range to an "N" range or a "P" range when a stoppage detecting means has detected that the vehicle is in its substantially stopped state, a torque command value gradually-decreasing means gradually decreases the torque command value for the motor toward zero. This causes the face pressure of meshed portions of gears within the transmission to be moderately decreased, thereby preventing the generation of a striking sound due to a repulsion of the gear.
