ELECTRICALLY-DRIVEN VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an electrically-driven vehicle furnished with a substitute means of a steering angle sensor. SOLUTION: Motor generators IWMR, IWML are respectively built in front wheels FR, FL and respectively drive the front wheels FR, FL. An ECU 30 computes motor rotational frequency MRNR, MRNL of the motor generators IWMR, IWML in accordance with signals from rotation sensors 20R, 20L. Additionally, the ECU 30 computes an operation angleΔθof steering by multiplying a differential value of the motor rotational frequency MRNR, MRNL by a previously set conversion coefficient.
