General
The accelerator pedal sensor (1) converts the mechanical actuation of the accelerator pedal into a voltage signal that corresponds to the accelerator pedal position.
Function
The accelerator pedal sensor (1) is integrated on the accelerator pedal pivot. The accelerator pedal sensor (1) consists of a shaft with ring magnet. The ring magnet rotates in a printed circuit board with stator in two fixed Hall elements. This produces a change in the voltage.
The accelerator pedal sensor (1) is integrated in the accelerator pedal module. Depending on the equipment, either a passive or a haptic accelerator pedal module is installed.
Passive accelerator pedal module
The passive accelerator pedal module is used with all conventional drives. The driver's request is determined as a digital signal on the basis of the accelerator pedal position by means of two redundant sensors that operate inductively and record angles, and transmitted to the electronics.
Haptic accelerator pedal module
The haptic accelerator pedal module is installed in plug-in hybrids.
The haptic actuator is used to generate an additional surge in power. The additional surge in power can be switched in and off via the actuator integrated in the haptic module. When the additional surge in power is switched off, the haptic accelerator pedal behaves like a passive drive module.
In the ("ELECTRIC") drive program in the plug-in hybrid, the surge in power is activated and enables fully electric operation of the vehicle up to the additional pressure point.
If the pressure point is overpressed, the combustion engine is switched in and supplies additional drive torque.
The haptic accelerator pedal can help to reduce fuel consumption and the exhaust gas emissions of the hybrid vehicle.
Limp-home mode
If the signal voltage of a Hall element fails, the signal voltage of the second Hall element is used and the engine enters limp-home mode.
