Abstract: A brake control device includes a control unit configured to calculate a target current value, which is a target current value to the motor, based on master cylinder hydraulic pressure, and reduce an energization level to the motor when an actual current value, which is an actual current value to the motor, reaches the target current value, set a hydraulic pressure threshold value, which is a threshold value of the master cylinder hydraulic pressure corresponding to a braking force necessary for the vehicle to stop based on an inclination angle of a road on which the vehicle is stopped, and calculate a time change amount of the master cylinder hydraulic pressure, and in a case where the time change amount exceeds a predetermined change amount, increase an energization level to the motor when the master cylinder hydraulic pressure subsequently becomes less than or equal to the hydraulic pressure threshold value.

Abstract: A vehicle speed control device executes a reverse speed control that controls the speed of the vehicle when reversing, on the basis of a target speed that is set in accordance with a control operation when the reverse range is selected using the shift device of the vehicle. During the reverse speed control, the vehicle speed control device calculates so as to reduce a target acceleration. which is a target value for acceleration of the vehicle when the vehicle speed when reversing is increased toward the target speed, as the operation amount of the steering wheel increases.

Abstract: This vehicle brake device performs raising processing for raising, by a predetermined raising amount, the target hydraulic pressure of hydraulic fluid when the pressure of the hydraulic fluid starts increasing in order to suppress a delay in response to the increase in the pressure of hydraulic fluid during switching processing for gradually switching at least part of regenerative braking force to hydraulic braking force, and includes a judging portion which judges whether or not required braking force or deceleration is reduced during cooperative control; and a raising amount setting portion which during the raising processing, sets a second predetermined pressure as a raising amount if the judgement result of the judging portion is positive, the second predetermined pressure being smaller than a first predetermined pressure that is the raising amount when the determination result of the determination result is negative.
