Torque Vector Control

Torque vectoring control applies the brakes on the inner driven wheel while in a curve for better traction to avoid an understeer or oversteer situation. Unlike ESC, torque vectoring control does not reduce engine RPM or slow the vehicle. It aids in controlling excessive wheel slip giving the vehicle improved cornering ability.

The ABS module continuously monitors and compares the rotational speed of the drive wheels in relation to the non-driven wheels. When torque vectoring control is needed, the ABS module modulates brake pressure to the appropriate brake calipers by opening and closing the appropriate solenoid valves while activating the hydraulic pump motor. At the same time, the ABS module sends a stability event message to the GWM over the FD-CAN which relays this message to the IPC over the HS-CAN3. When the IPC receives the traction event message, it flashes the stability-traction control indicator (sliding car icon).

Once the stability event is over, the ABS module deactivates the hydraulic pump motor and solenoid valves, and stops sending the traction event and torque reduction messages. The IPC extinguishes the stability-traction control indicator (sliding car icon).
