MODEL BASED DIAGNOSTICS BASED ON STEERING MODEL

摘要

A steering application executing on a vehicle control module receives a steering control input to control a steered wheel of a vehicle and, based on the steering control input, determines a setpoint value for the steered wheel. A diagnostic supervisor receives a measured value of the control attribute and the setpoint value; wherein the first diagnostic supervisor comprises a first model of a steering system of the vehicle. Based on the setpoint value and the first model, the diagnostic supervisor calculates a virtual value of the control attribute and, based on the virtual value and the measured value of the control attribute the first diagnostic supervisor determines an operating condition of the steering system of the vehicle.
