Abstract: Anti-lock and intelligent braking systems have become ubiquitous in modern vehicles, which employ wheel speed sensors or WSSs. These WSSs generally uses current-domain signals (transmitted through power wires) to reduce the size of the vehicle's wiring harness, but because a vehicle is an inherently noisy environment, mixed signal circuit or MSC (used to decode these signals for a microcontroller) should be able to filter out or compensate for noise. However, traditional MSCs have been plagued with problems, partly due to errors in time base measurement due to noise (as well as other factors). Here, an MSC is provided that accurately calculates a wheel speed pulse width (which is used for time base measurements) by observing the wheel speed pulse as it passes through several thresholds.
