In late July 2011, Bosch electric vehicles for official said brake pedal recently developed a series of brake pedal travel sensor PWG (PedalTravelSensor), to help electric cars and hybrid vehicles to achieve regenerative braking system functions.

    Bosch's new series of the PWG and the pedal travel sensor contains PWG12 PWG13 two designs, with the following characteristics: 1, non-contact operation; 2, using the signal output of more than (RedundantSignalRecording), redundant signal recording function, which ensure that the vehicle has high security; 3, equipped with magnetic sensors (MagneticFieldSensor), wear-free pedal travel to fully measure the effect.

    PWG Series pedal travel sensor measuring principle to Hall (Hall) sensor design, based on the magnetic field of the magnetic vector can be recorded. In addition, PWG series of pedal travel sensor can also be carried out according to the different properties of the pedal cut processing. Thus large-scale manufacturers can purchase the product by programming the sensor processing and control unit to implement the corresponding parameters of (Parameterized), which respond to different vehicle needs.

    From the progress of the point of view, two designs are already available test samples, according to the plan in the near future will be put into mass production.
