Absolute Steering Angle Sensor

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.

Absolute steering angle sensor.

The use of sasa sensor is relevant e g. The steering angle sensor sas is a critical part of the esc system that measures the steering wheel position angle and rate of turn. The sas is located in a sensor cluster in the steering column. To this end the invention proposes featuring two preferably concentric circular tracks 1 2 wherein the first track 1 is used to.

But the steering angle sensor has two or three sensors packaged together. The only other sensors on a vehicle like this are the throttle angle sensor and gas pedal for vehicles with throttle by wire. Steering wheel position the sasa sensor detects the absolute position and speed of the steering wheel. The sensor can be used in electro hydraulic steering systems using danfoss ospe eh or ehps steering valves with programmable controllers.

The invention relates to a steering angle sensor for motor vehicles. 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. There is one crankshaft position sensor one wheel speed sensor per wheel and only one output sensor on the transmission. A method for detecting an absolute steering angle of a steering angle sensor such as encoder for a vehicle wherein the steering angle sensor generates an output signal indicating a relative rotation angle of a steering shaft of the vehicle and at least one reference signal representing a reference position for every one rotation of the steering shaft.

A scan tool can be used to obtain this data in degrees.
