Description
Summary:The wheel torque arbitration and coordination strategy of the P2.5 hybrid system is based on the stability limitation control, the regen torque and the motor shift torque coordination. The specific contents are as below: 1)The wheel torque arbitration control. The driver acceleration torque request and regen torque request are arbitrated in this part.2)The stability limitation control. The torque request from the chassis system is arbitrated in the stability limitation. There are 3 main torque requests from the stability controller: the dynamic stability control, slip regulation and crash control.3)The wheel torque coordination control. The wheel torque coordination is basically responsible for handling the motor assist torque, the regen torque and the motor shift torque to the propulsion actuators. This torque request is distributed to the crankshaft torque and motor torque.The vehicle results are conducted and show that the wheel torque strategy can follow the driver torque and the good drivability performance can be achieved.
