Absolute Steering Angle Sensor

The use of sasa sensor is relevant e g.

Absolute steering angle sensor.

The invention relates to a steering angle sensor for motor vehicles. The cluster always has more than one steering position sensor for redundancy and to confirm. The sas is located in a sensor cluster in the steering column. The only other sensors on a vehicle like this are the throttle angle sensor and gas pedal for vehicles with throttle by wire.

A scan tool can be used to obtain this data in degrees. The object of the invention is to be able to provide the absolute value of the steering angle position of the steering wheel within a relatively short angle of rotation of the steering wheel. There is one crankshaft position sensor one wheel speed sensor per wheel and only one output sensor on the transmission. For variable steering ratio and closed loop set ups where steering.

To this end the invention proposes featuring two preferably concentric circular tracks 1 2 wherein the first track 1 is used to. The sensor can be used in electro hydraulic steering systems using danfoss ospe eh or ehps steering valves with programmable controllers. But the steering angle sensor has two or three sensors packaged together. Detecting the absolute position and speed of the steering wheel is important in variable steering ratio and closed loop set ups where steering wheel position and steering angle have to match.

The steering angle sensor sas is a critical part of the esc system that measures the steering wheel position angle and rate of turn.
