Brake pedal sensor: movement converted to request

Useful to know

The angle sensor of the brake pedal takes into account its movement and position. Bosch describes contactless magnetic measurement and reserved reading of the driver's desired braking. Information may be involved in the control of various braking systems. [1]

It is important to distinguish measurement and performance. The sensor communicates what is happening to the pedal; other components and control logic determine how to realize the braking. This is not the same sensor as the one for the steering wheel angle.

When describing a malfunction, record the exact symptom and message on the scoreboard. The mere presence of an electronic sensor does not allow remote diagnosis of one sentence. The reserved signal is a constructive feature of the described solution, not a promise that any possible failure is without consequences. The specific vehicle and its service documentation determine the checks.
