Abstract: The braking device for vehicles includes a reduction amount setting part for setting the amount by which to reduce the revolution of a pump motor during maintenance or reduction of controllable differential pressure so that the reduction amount decreases as the probability increases of needing to discharge the brake fluid by pumps, during a period from when a brake controller begins reducing the revolution until the lapse of prescribed time.

Abstract: A braking control device includes: a control unit that is configured to control front-wheel braking power and rear-wheel braking power based on braking power distribution and requested braking power; a distribution setting unit that is configured to set the braking power distribution; and a slip judgment unit that is configured to judge whether or not the vehicle is in a rear-wheel-led slip state. If it is judged that the vehicle is in the rear-wheel-led slip state when the braking power distribution is first braking power distribution, the distribution setting unit executes a distribution shifting process of shifting the braking power distribution to second braking power distribution within a predetermined period. The second braking power distribution is such distribution that the rear-wheel braking power is reduced relative to that observed when the first braking power distribution is set as the braking power distribution.

Abstract: A control device of a vehicle controls an actuator of the vehicle to cause the vehicle to travel based on a follow-up route. The control device includes a width information obtaining unit that obtains a road width in which the vehicle can pass on a road on which the vehicle travels. The control device includes a locus follow-up control unit that creates a follow-up route based on the obtained road width. The locus follow-up control unit derives a control amount for causing the vehicle to travel along the follow-up route.

Abstract: A control device of a vehicle controls an actuator to cause the vehicle to travel based on a target locus. The control device includes a travel assisting unit that generates a target locus and sets a point on the target locus as a target position. The control device includes a braking control unit capable of communicating with the travel assisting unit. The braking control unit executes a process of calculating a control amount for causing the vehicle to follow the target position received from the travel assisting unit. The braking control unit executes a process of instructing the actuator to perform driving based on the control amount.

Abstract: A travel assist device includes: a creation unit configured to create a traveling profile based on a total traveling distance; and an output unit configured to output an operation amount according to a target state amount, which is a target value of a state amount indicated by the traveling profile, to at least one of a driving device and a braking device. In a state in which a vehicle travels by the driving of at least one of the above devices based on the operation amount, the creation unit re-creates a traveling profile so that the acceleration of the vehicle does not exceed a predetermined limit value if the difference between an actual value of the state amount and the target state amount is equal to or larger than a judgment difference.

Abstract: A brake control device of a brake device includes a first acquisition unit acquiring an operating force PF inputted to a brake pedal, a second acquisition unit acquiring a stroke amount SS of the brake pedal, a target derivation unit deriving a target braking power BPTr based on the operating force PF and the stroke amount SS, and a brake controller controlling a vehicle braking power based on the target braking power BPTr. The target derivation unit increases or holds the target braking power BPTr when the operating force PF decreases while the stroke amount SS increases.

Abstract: A brake operation unit includes, for example, a master cylinder that movably houses a piston moving in connection with an operation member; an electric discharging unit including a motor and a discharging mechanism that is caused to discharge a working fluid by operation of the motor; and a reaction force applying mechanism that applies a reaction force to the operation member. A second central axis of the motor is separated from a first central axis of the master cylinder, and intersects a direction parallel to the first central axis. When viewed in a direction parallel to the second central axis, the first central axis is located between the second central axis and the reaction force applying mechanism.

Abstract: The present disclosure provides a brake control device applied to a vehicle including a hydraulic brake device that generates a hydraulic braking force by pressing a braking member with hydraulic pressure toward a member-to-be-braked that rotates integrally with a wheel; and an electric brake device that generates an electric braking force by pressing the braking member by driving a motor toward the member-to-be-braked. A controller that controls the electric brake device is provided. The controller executes, when a predetermined condition is satisfied, a positional control for driving a motor and moving a propeller shaft that transmits the driving force of the motor to the braking member toward the member-to-be-braked as compared to when the predetermined condition is not satisfied.
