Abstract :
Recently, vector control methods without a speed sensor for electric vehicles are under discussion. The authors propose a new method of slip detection without a speed sensor by focusing on the current of each motor. The proposed method makes it easier to detect small slips. Furthermore, the adhesion force is presumed in order to determine the current recovery value based on the behavior of motor current when a slip occurs. Thus the detection of small slip can be compatible with the hold of high motor current. We performed simulation to verify the effectiveness of the proposed readhesion control method that uses the presumed adhesion force
