Pedal Value Sensor Characteristic Curve When Reversing Function




B37 Accelerator pedal sensor
M16/1 Actuator EFP/TPM/LLR (further designation: M16/6 Throttle valve actuator)
N3/10 Motor electronics control unit
N15/3 ETC control unit (with automatic transmission)
S16/2 Backup lamp switch (with manual transmission)
CAN Data bus

Task
Optimizing driving comfort and safety when reversing.

Design/function
The pedal value sensor charcteristic curve is changed if reverse travel is recognised by the ME control unit. The throttle valve opens more slowly. The entire opening angle in this case is approx. 50%.
Reversing is detected:
- if a manual transmission fitted, the ME control unit is connected parallel to the reversing light switch.
- if an automatic transmission is fitted, the information is supplied over the CAN by the ETC control unit.
