Abstract
A driving controller of electric vehicles. An angular accelerative dimension error calculator calculates error information having a dimension of angular acceleration of a car body. A feedback torque calculator calculates the feedback torque on the basis of the error information according to the sign of a steering angle and the error information, and ON/OFF of an accelerator. A vehicle controller corrects the reference torque, determined according to an accelerator angle and braking force, by the feedback torque, and outputs the corrected reference torque toward motor controllers, thereby improving vehicle running safety.
