An abnormal torque evaluation apparatus is applied to an electrically driven vehicle configured to drive left and right driving wheels independently with respective electric motors and also configured to independently drive the left and right driving wheels by means of the electric motors driven responsively to respective torque commands. Also provided are a yaw jerk detection means for detecting a yaw jerk and an abnormal torque evaluator for evaluating, based on the yaw jerk, the presence or absence of the occurrence of abnormal motor torque at the electric motors.

In a continuously variable transmission which varies a speed change ratio based on a target speed change ratio which has been set according to a running condition of a vehicle, a sensor is provided for detecting the temperature of the continuously variable transmission. A shift amount of the speed change ratio due to a thermal expansion difference of parts of the continuously variable transmission is prevented by correcting the target speed change ratio based on the temperature detected by the sensor.
