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. 在车辆控制模块上执行的转向应用接收用于控制车辆的转向轮的转向控制输入，并且基于转向控制输入确定转向轮的设置点值。诊断监督程序接收控制属性的测量值和设置点值；其中第诊断监督程序包括车辆的转向系统的第模型。基于设置点值和第模型，诊断监督程序计算控制属性的虚拟值，并且基于控制属性的虚拟值和测量值，第诊断监督程序确定车辆的转向系统的操作状况。
