Wheel Speed Sensor | HELLA 6PU 012 679-541

Intelligent communication of data between electronic vehicle systems is supported by sensors. When it comes to driving safety, speed sensors play a particularly important role, and this is reflected by their varied use in a number of different vehicle systems. They are used by the control units in driving assistance systems such as ABS, TCS, ESP, or ACC in order to detect the wheel speed.

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. As a result of their varied use, speed sensors contribute directly to the driving dynamics, driving safety, driving comfort, lower fuel consumption, and lower emissions. Wheel speed sensors are often also called ABS sensors as they were used in vehicles for the first time when ABS was introduced.
