Abstract:
The system (10) is configured to detect high friction in a steering gear used with a vehicle. The system (10) has a speed sensor (17), a steering angle sensor (17, 108), a plurality of vehicle sensors (23, 112) to monitor vehicle parameters and a plurality of steering system sensors (17, 108) to monitor steering system parameters. A repository stores (27, 120) the normal operating values for the vehicle and steering system sensors (17, 108). A correlation block (21, 130) compares the vehicle and steering system values with the values in the repository (27, 120). A trigger block (15) receives signals from the speed and steering angle sensors, and activating the correlation block (21, 130) when the speed and steering angle sensors are in a select range. The correlation block (21, 130) sends a warning signal if the values from the repository (27, 120) and the signal from the speed and steering angle sensors (17, 108) exceed a predetermined value.
