Fail operational steering angle sensor

A Fail Operational Steering Angle Sensor (10) for vehicles, comprising

• a disk-shaped hub (130) comprising a central circular opening;
• at least two disk-shaped outer gears, gear A (150) and gear B (140), mechanically connected to the disk-shaped hub (130) by means of protruding teeth in an outer rim of the disk-shaped hub (130) and an outer rim of the at least two disk-shaped outer gears;
• a disk-shaped rotor (120);
• and
• a printed circuit board (110) arranged over the disk-shaped hub (130), the at least two disk-shaped outer gears, and the disk-shaped rotor (120);
• wherein
• the disk-shaped rotor (120) is arrangede between the printed circuit board (110) and saiddisk-shaped hub (130)
• the disk-shaped hub (130) comprises a drive key (131) located in the central circular opening to mechanically connect to a Steering Wheel Actuator (SWA) shaft (125) by a first connection;
• and
• the disk-shaped rotor (120) is independently connected against the SWA shaft (125) by a set of punches forming a second connection different from the first connection, whereby the first connection of the disk-shaped hub (130) and the second connection of the disk-shaped rotor (120) provide two different and independent mechanical paths between the SWA shaft (125) and the seosnr (10).
