A motor controlling apparatus for a vehicle is provided to minimize the amount of torque throttle by preventing other shaft from being slid by the movement of load of a shaft. A motor controlling apparatus for a vehicle includes acceleration detecting and controlling units(26a~26f), sliding speed detecting and controlling units(27a~27f), and switching controlling units(28a~28f). The acceleration detecting and controlling units are installed on each inverter(11a~11f), and throttles the torque when detects the increase of time variation of speed signal of motors(12a~12f) over a predetermined value. The sliding speed detecting and controlling units are installed on each inverter, and throttle the torque in correspondence to the increase of the speed signal of the motors at predetermined reference speed. The switching controlling units switch the inverter which controls the motor located on the rear side of each car body(23) along the driving direction of the car to be controlled by the acceleration detecting and controlling unit, and the inverter which controls other two motors to be controlled by the sliding speed detecting and controlling unit. |
