Control system for electric vehicle

A control system for an electric vehicle, comprising:

• at least two electric motors for independently driving left and right wheels of the vehicle;
• power supply means for supplying power to said motors;
• means for detecting command entered by a driver of the vehicle and driving operational amount provided for said vehicle;
• means for detecting a vehicle speed of the vehicle;
• means for detecting a steering angular position;
• means for calculating torque difference command signals of said left and right motors on the basis of the detected vehicle speed and said steering angular position;
• means for detecting output torques of said two motors and calculating a difference therebetween;
• means for calculating a motor speed difference command signal for making the difference of said two output torques consistent with said torque difference command signals;
• means for calculating a vehicle speed command signal for said vehicle on the basis of detected command and said driving operational amount;
• means for calculating motor speed command signals for respective of said motors on the basis of calculated motor speed difference command signal and said vehicle speed command signal;
• means for detecting actual speeds of said two motors;
• and
• control means for voltage controlling supply power from said power supply means to said motors so that the detected actual speeds of said motors become consistent with said motor speed commands for respective motors.
