PROBLEM TO BE SOLVED: To provide a motor output controller for an electric vehicle which can reduce the operation load of a driver by suppressing the change of the vehicle action of a vehicle caused by the change of the longitudinal position of the center of gravity, without mounting special hardware, in an electric vehicle whose wheels on one side are in such form that they do not generate lateral forces such as casters or the like out of either front or rear wheels, and which enables turn motion by the difference of driving forces between right and left wheels on the other side. SOLUTION: This motor output controller is equipped with a vehicle velocity detection step S402 which detects the velocity of a vehicle, a turn command detection means 21 which detects the turn command of the vehicle, acceleration/deceleration command detection means 22 and 23 which detect acceleration/deceleration commands of the vehicle, a step S705 for estimating the longitudinal position of the center of gravity of the vehicle which estimates the longitudinal position of the center of gravity of the vehicle, and a motor output calculating means 30(integrated controller ) which calculates outputs of motors 3RL, 3RR, according to the vehicle velocity V and the longitudinal position of the center of gravity cLr so as to obtain the turn command and the acceleration/deceleration command.
