MSR engine-drag torque control prevents the driven wheels from locking due to the braking effect of the engine on slippery surfaces when the driver suddenly takes his foot off the accelerator or rapidly shifts down a gear. The braking effect of the engine may cause the driven wheels to skid. They temporarily lose traction and the vehicle becomes unstable. In such situations, engine-drag torque control maintains directional stability and boosts safety. The control unit of the engine-drag torque control system receives all the necessary information from the wheel-speed sensors and the engine control unit or transmission control unit via the CAN data bus. If the control unit detects that the driven wheels are slipping, the engine-drag torque control system sends a signal via the CAN data bus to the engine control unit indicating that engine torque should be increased, until the driven wheels are once again turning at a rate appropriate to the speed of the vehicle. This keeps the vehicle steerable and ensures that directional stability is maintained. Engine-drag torque control functions across the entire speed range.
