Document Type and Number:
WIPO Patent Application WO/2020/027066
Kind Code:
A1
Abstract:
A control device 10 is applied to a vehicle which is provided with a steering device 30 that changes a tire angle in synchronization with a change in steering angle while assisting in steering by driving an electric motor 31. The control device 10 performs steering assistance control for changing the tire angle and the steering angle by driving the electric motor 31 on the basis of a target tire angle. The control device 10 is provided with a control drive amount calculation unit 23 that calculates a control drive amount based on the target tire angle while the steering assistance control is being executed. The control device 10 is provided with a steering drive amount calculation unit 24 that calculates a steering drive amount that is the drive amount of the electric motor 31 according to the steering torque. The control device 10 is provided with a control unit 25 that, when steering is performed in a state in which the steering assistance control is being executed, calculates the sum of the control drive amount and the steering drive amount as a cooperative drive amount and controls the electric motor 31 on the basis of the cooperative drive amount.
