How can I detect the reverse rotation of the Car wheel? I know that vehicles have VRS (Variable reluctance sensor) or Hall sensor for wheel speed sensing. I think, the voltage from the sensor will be the same, for both directions(since the trigger wheel in shaft will cut the flux). Is there any other way say like a algorithm to identify this? for eg, by looking at the gear position and the clutch pedal input, or with brake pedal input.
I didn't find the right solution from the Internet.
