Kickdown, function

The driver's request for maximum acceleration of the vehicle is fulfilled by the kickdown function.

The kick-down function is activated from a pedal travel at the electronic accelerator > approx. 90 %.

Furthermore the driver can detect an increase in pedal effort at the kick-down point. For this purpose a kick-down simulator is integrated in the electronic accelerator.

The "Kick-down" signal is recorded by the accelerator pedal module, read in by the ME-SFI [ME] control unit (on vehicles with M 272) or by the CDI control unit (N3/20) (on vehicles with OM 642) or by the CDI control unit (N3/21) (on vehicles with OM 646) and passed on via the Controller Area Network bus class C (engine compartment) (CAN-C) to the ETC [EGS] control unit.

Based on this information the ETC [EGS] control unit actuates the solenoid valves so that the upshifts and downshifts take place at increased engine speed in order to achieve the maximum performance.
