Engine drag torque control
The engine drag torque control ( MSR ) is a driver assistance system that is usually part of the electronic stability program ( ESP ) and traction control ( ASR ).
The MSR prevents the drive wheels from slipping, especially on slippery roads , if the driver suddenly takes off the accelerator or lets the clutch come too quickly when downshifting. According to Kamm's circle , the maximum power transmission capacity of the tires between vehicle and road may be exceeded here due to the braking effect of the engine. The control unit of the engine then controls, if necessary, the engine speed corresponding to the short term high to keep stable and steerable about the vehicle.
