Torque Vectoring Control Strategies Comparison for Hybrid Vehicles with Two Rear Electric Motors

In today’s automotive industry, electrification is a major trend. In-wheel electric motors are among the most promising technologies yet to be fully developed. Indeed, presence of multiple in-wheel acting as independent actuators allows for implementation innovative active systems and control strategies. This paper analyzes different design possibilities torque vectoring system applied an originally compact front-wheel drive hybrid vehicle with one internal combustion engine front axle two added integrated in wheels rear axle. A 14 degrees freedom model present o accurately reproduce nonlinearities dynamic phenomena exploited obtain high-fidelity numerical simulation results. Different methods compared, PID, LQR, four sliding mode All controllers achieve sufficiently good results terms lateral dynamics compared basic version. The various aspects features strategies analyzed discussed. Chattering reduction developed improve performance controllers. For complete overview, using factor that weighs accuracy effort driving maneuvers, i.e., ramp step steering maneuvers performed under quite conditions ranging up limits.
