Abstract: A control device is applied to a vehicle including a steering device changing a tire angle in synchronization with a change in a steering angle while assisting in steering by driving an electric machine. The control device performs a steering support control for controlling a tire angle and a steering angle by driving the electric machine. The control device includes a control drive amount calculation unit calculating a control drive amount based on the target tire angle in a state where the steering support control is executed. The control device includes a steering drive amount calculation unit calculating a steering drive amount being a drive amount of the electric machine related to a steering torque. The control device includes a control unit that controls the electric machine based on the cooperative drive amount, during steering movement of the driver in a state where the steering support control is executed.

Abstract: This vehicle brake device comprises: a simultaneous driving determination section which determines whether it is necessary to simultaneously drive an upstream-side motor and a downstream-side motor; and a PWM control section which, when the determination result by the simultaneous driving determination section is in the affirmative, changes the duty ratio of the PWM signal to be output to the upstream-side motor so as to be smaller than when the determination result by the simultaneous driving determination section is in the negative, and uses PWM control to drive the upstream-side motor.

Abstract: A control device is applied to a vehicle that has a braking device configured to be able to adjust the braking force applied to the vehicle. The control device has a stopping braking force imparting unit that controls the braking device in order to apply a stopping braking force to the vehicle, as a minimum value of the braking force required to keep the vehicle stopped. The control device also has a deviation quantity deriving unit that derives a deviation quantity between a state quantity of the vehicle obtained when the stopping braking force is applied to the vehicle by the stopping braking force imparting unit and an ideal value of the state quantity of the vehicle. The control device also has a stopping braking force updating unit that updates the stopping braking force on the basis of the deviation quantity derived by the deviation quantity deriving unit.
