  • Hi-resolution digital steering sensor fault detection
    Patent number: 6721639
    Abstract: A system and method for digital steering sensor fault detection comprises monitoring steering wheel position information from a digital steering wheel position sensor at set time intervals, determining steering wheel position information for the current time interval and the previous time interval, and advancing a value change counter if the steering wheel position information for the current time interval is the same as for the previous time interval; monitoring vehicle speed, and advancing a speed cycle counter when the vehicle speed crosses a first threshold speed after crossing a second threshold speed; and setting fault bit information if the value change counter is zero after the speed cycle counter reaches a speed cycle limit. The steering wheel position information can be for a plurality of digital steering wheel position sensor outputs and provide corresponding fault bits, which can be compared to a fault table to diagnose a particular fault.
