Controller for vehicle steering apparatus and method for detecting abnormality in the controller |
摘要 |
A vehicle steering apparatus controller that enables a sub-computer having a capacity lower than that of a main computer to recognize computation results in the same control cycle as the main computer. A main computer of the controller computes an auxiliary torque command value of a steering motor based on the torque of a steering wheel and the velocity of the vehicle in a main control routine. A sub-computer of the controller computes a value equivalent to the command value based on the torque and the vehicle velocity in each cycle of a sub-control routine, which is longer than that of the main control routine. The sub-computer includes a first comparison circuit for comparing the command value and the torque in each cycle of the main control routine and a second comparison circuit for comparing the command value and the equivalent value in each cycle of the sub-control routine.
