Wheel Speed Sensors (WSS) provide essential wheel rotational information to safety relevant control systems as anti-lock system (ABS), traction control (TCS) or electronic stability control (ESC) as well as to a large number of comfort functions and systems in modern vehicles. Even electric driven cars utilize wheel speed information to control and plausibilize electric motor motion.

Redundant Wheel Speed SensorThe dual signal wheel speed sensor is a product providing two electrically isolated wheel speed sensor signals (ISO26262 compliant) to the vehicle systems. Redundant brake systems for Highly Automated Driving applications with L3 or higher driving functions can be achieved.

The AUMOVIO High Resolution Wheel Speed Sensor is providing a finer resolution of wheel rotation information as current existing Wheel Speed Sensors.

The integration of both functions (wheel speed signal transmission) and EPB power transmission is assured by a special 4 wire cable design having high bending durability performance, less connector interfaces and low electric resistance. The integrated WSS cable and its functions are a carry-over of the single WSS cable technology.

The control systems for ABS, TCS and ESC determine the wheelspeed based on signals supplied by the wheel speed sensors. This information is used to prevent the wheels from locking or slipping, taking appropriate control action to maintain the vehicle’s stability and steering responses.

Stand-alone, contactless sensor providing the position of the camshaft and the crankshaft by reading a ferromagnetic or magnetic encoder wheel mounted on the engine camshaft and crankshaft respectively.

Stand-alone contactless active sensor providing exact position ofthe camshaft by detecting the rotation of a ferromagnetic ormagnetic encoder wheel.Output signal is used by the Engine Management System (EMS) todetermine the engine position at start and to control the VVT (Variable Valve timing) actuator.

Stand-alone, contactless sensor providing the position and rotation direction of the crankshaft by reading a ferromagnetic or magnetic encoder wheel mounted on the engine crankshaft.
