System Interplay
The engine electronics (ME) is used to adjust the drive torque. This system controls the engine by adjusting the position of the throttle valve and by altering the ignition timing. The gear setting is also evaluated by the electronic transmission control (EATC) to calculate the ESP drive torque control.
The ABS and ASR functions are integrated in the ESP electronics of the brake control loop. In the following vehicles it also includes the BAS function (as of 3/99): Model 202 with engines 111, 112, 113. The basic ABS and ASR components are also combined in the ESP hydraulic unit.
The function for the electronic gas pedal (EGP) and cruise control is contained in the engine control unit. Data is exchanged between the ESP control module, the engine control unit and (if fitted) with the transmission control module and BAS control via a CAN data line.
