This Steering wheel angle sensor is most important component in automotive vehicle. For +/-720°-degree rotation measurement of steering wheel need a special design, since conventional sensors measuring angle of rotation can measure only 360°. The steering wheel angle has to be resolved over the complete range at any time and the data should be available to the other subsystems which use this angle data available immediately after the system power on. In this paper describe a Steering Angle Sensor for a +-720° (a total of 4 complete turns) acquisition with the application of Giant Magnetic Resistance (GMR) sensors. For control tasks and further applications, the angle data need to be provided over a Binary Unit System (BUS) like Controlled Area Network to other system participants. This set-up provides reliable and fast angle values. © 2017 IEEE.
