Torque Distribution Strategy of Electric Vehicle with In-wheel Motors Based on the Identification of Driving Intention

A driver’s intention is recognized accurately by employing fuzzy identification and a logic threshold including acceleration intention and steering intention. Different torque distribution control strategies are developed for different intentions and the driver’s torque demand is amended by fuzzy identification so that the response of the vehicle is more consistent with the driver’s intention of operation. Finally, a simulation model is built using MATLAB/Simulink to validate the control strategy. Simulation results show that the system accurately identifies the driver’s intention and improves the acceleration performance and steering stability of the vehicle.
