To provide an abnormal motor temperature detector for an electric vehicle that reduces prevents a normal temperature detection system of a motor from being falsely determined to be abnormal.

An abnormal motor temperature detector includes: a temperature estimation means for estimating the temperatures of driving motors for driving a plurality of wheels independently, a temperature detection means for detecting an actual temperature value of each driving motor, an error detection means for detecting an error between the estimated temperature value estimated by the temperature estimation means and the actual temperature value detected by the temperature detection means for each driving motor, an error difference calculating means for calculating a difference between the errors obtained for each driving motor by means of the error detection means, and an abnormal temperature determination means for determining whether the temperature is abnormal or not in the driving motors based on the difference between the errors calculated by the error difference calculating means.
