Torque Distribution Control Strategy based on Dynamic Axle Load for 8 In-Wheel Motor Drive Vehicle☆

Abstract Compared with conventional internal combustion engine vehicle, the vehicle with multi-wheel independent technology has apparent advantages on vehicle dynamics control and driving force distribution. The target system of this study is the vehicle driven by wheel hub motors (8×8). The model of some key components is built, including the vehicle dynamics, suspension, wheel hub motor, tires. The dynamic system model of 8×8 vehicle is modeled and co -simulated with Matlab/Simulink. The controller takes the vehicle longitudinal velocity and the yaw rate as the observation object. The rules have a greater advantage in the engineering applications. And the algorithm is fast, so it can improve the vehicle maneuverability in a certain extent.
