WebApr 1, 2024 · An indirect TPMS typically relies on wheel speed sensors that the anti-lock brake system uses. These sensors measure the rate of revolution each wheel is making and can be used by on-board computer systems to compare with each other and to other vehicle operation data such as speed. WebMagnetic wheel speed sensors It used to be that only antilock braking systems (ABS) needed to know if a wheel was blocked, and only electronic stability control (ESC) used the speed of all four wheels to course correct vehicles veering away from their intended path.

WebThis sensor is mounted a fixed distance from a ferromagnetic rotor with teeth. As the rotor turns and a tooth comes into the proximity of the rod, the magnetic flux in the coil changes. This change in flux results in a voltage pulse across the coil. The vehicle's engine control module counts these voltage pulses and computes the vehicle's speed. WebFeb 28, 2024 · 2. The sensor has no need to know the wheel size. Both ANT+ and BTLE protocols the sensor only transmits the wheel revolution count and the time taken for the last revolution. The head unit converts this to speed and it's the head unit that need to know the wheel size. In practice the wahoo sensor has some filtering on the last revolution time ... WebThis drop in hydraulic pressure allows the wheel to spin instead of skidding. Four-channel ABS systems found on today's vehicles have a wheel speed sensor (WSS) at each wheel.
