Kickdown, function
The driver's wish for the maximum vehicle acceleration is met 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. A kick-down simulator (100) is integrated in the electronic accelerator for this purpose.
The "kick-down" signal is recorded by the accelerator pedal sensor (B37), read in by the ME control unit (N3/10) or the CDI control unit (N3/9) and relayed via the class C controller area network bus (engine compartment) (CAN-C) to the fully integrated transmission control (VGS) control unit (Y3/8n4).
On the basis of this information, the fully integrated transmission control (VGS) control unit (Y3/8n4) actuates the control solenoid valves such that upshift and downshift operations take place at increased engine speed to achieve maximum performance.
