Description
What does the ABS sensor do and how?
In short the ABS sensor, monitors the wheel’s speed and rotation to optimize both brake and traction control via the ABS. Typically installed at the wheel, it consists of two components: a reluctor wheel or tone ring positioned on the axle, which rotates with the wheel, and either a magnetic or hall effect sensor which sends the data to the ABS control module. The wheel speed data is used to determine when to activate the ABS and how much pressure it should safely apply to stop the vehicle without locking up the brakes. The wheel speed information is also provided to other systems (engine, transmission, navigation, and chassis control systems) via data lines by the ABS control unit.
