Abstract: The authors propose a sensor less hill start assist control method and use the vehicle controller to collect relevant signals to determine whether to enter the hill start assist mode. They design a dual closed-loop PI controller to control the motor drive torque to realize the hill start assist control function and carry out real vehicle tests.
Key words: pure electric vehicle; hill start; assist control
