Reconfiguration control of in-wheel electric vehicle based on battery state of charge
2018 European Control Conference (ECC)
12-15 June 2018
The paper deals with reconfiguration control of electric vehicles operated by in-wheel motors and steer-by-wire steering system. The control reconfiguration is based on a power management method considering battery state of charge (SOC). In case the condition of the battery is critical and the vehicle is traveling on a slope, a high level reconfiguration is applied preferring yaw moment generation over steering actuation, by which energy recuperation can be improved and battery state of charge can be enhanced. The proposed control reconfiguration is implemented based on Linear Parameter Varying (LPV) framework, where a monitoring signal related to battery SOC scales the actuator selection. The operation of the presented power management method based on control reconfiguration is demonstrated in CarSim simulation environment.
