A study on the performance simulation and control scheme for in-wheel motor driven vehicles

An in-wheel motor drive system is designed for the land driving of multi-domain vehicle. A vehicle model is set up based on the in-wheel drive system and the drive control method is studied. On the basis of the theoretical analysis on steering dynamics, a multi-body dynamic model for vehicle is established with ADAMS. The driving and steering control strategies are proposed and the control model is developed with Matlab/Simulink. By using co-simulation scheme the driving performances of vehicle in typical working conditions including accelerating, steering and braking are validated. The results show that the basic performances of vehicle meet the expected objectives and the driving control strategy is effective.
