Fail operational steering angle sensor

A fail operational redundant steering angle sensor (100) comprising

• two functional blocks, functional block A (60) and functional block B (70);
• a galvanic insulation connection bridge (80) adapted to connect the two functional blocks;
• and
• at least two independent angling sensing devices, connected to both of the two functional blocks providing independent rotation angles;
• wherein the two functional blocks are adapted to determine the absolute angle of the at least two angling sensing devices and detect systematic and/or random failures of the at least two angling sensing devices.
