TCS/ESP

TCS/ESP





TCS/ESP request, general
In the event of wheel spin, TCS can request a limitation of engine torque (negative request) to counteract it. Likewise, ESP can request a limitation of engine torque if the car skids. TCS, but above all ESP, can request an increase in engine torque (positive request) to counteract a skid, for example.

Function principle, torque limitation during TCS/ESP control
ECM works with the throttle area and ignition timing control to reduce engine torque during TCS/ESP control. In the event of large limitations, turbo control will also be actuated to reduce engine torque.

Ignition timing control generates quicker torque changes, while regulating the throttle area is slower. Turbo control is the slowest.
