Embodiment
[0076] Such as figure 1 As shown, the present invention provides a four-wheel torque distribution control system for distributed drive electric vehicles. The system includes a motor controller and a motor torque distributor. The motor controller is provided with 4 drive motors respectively connected to the corresponding 4 wheels. The system also includes a vehicle state measurement unit, a control output constraint calculation unit, a torque control mode unit, a drive anti-slip control unit and a four-wheel torque distribution unit.
[0077] The four-wheel torque distribution control system calculates the control output constraints based on the obtained vehicle state information, and then judges the working mode according to the degree of wheel slippage. The torque distribution unit converts the expected total driving force and additional yaw torque required by the upper motion control layer into torque commands for the four drive motors, and the motor controller controls the ...
