Abstract: A vehicle controller sets an upper limit request value related to an upper limit of a longitudinal acceleration of a vehicle, a lower limit request value related to a lower limit of the longitudinal acceleration, and an acceleration request value related to the longitudinal acceleration that corresponds to an amount of the operation of the vehicle. The vehicle controller sets a first arbitration request value to a greater one of the lower limit request value and the acceleration request value. The vehicle controller sets a second arbitration request value to a smaller one of the first arbitration request value and the upper limit request value. The vehicle controller sets, to a value that corresponds to the second arbitration request value, a command value sent to an actuator that operates to adjust the traveling speed.

Abstract: A vehicle according to the present disclosure includes a brake device and an electronic control unit. The brake device is configured to change a front-rear distribution ratio of braking force with respect to front and rear wheels. The electronic control unit is configured to: control the brake device such that the front-rear distribution ratio is in accordance with a fixed distribution characteristic in which the front-rear distribution ratio is constant regardless of deceleration of the vehicle in at least a part of a first range being a required deceleration range lower than a lower limit value of the deceleration perceivable by a person in the vehicle; and control the brake device such that the front-rear distribution ratio is biased toward the rear wheel than that in the fixed distribution characteristic in a second range in which the deceleration is higher than that in the first range.

Abstract: A brake fluid pressure supply unit includes a fluid pressure generation device in which a piston that slides in a cylinder is driven by an electric motor to generate fluid pressure in a fluid pressure chamber formed in the cylinder; and a housing in which a fluid path connected to the fluid pressure chamber is formed. The electric motor and the cylinder are both attached to the housing. The electric motor is positioned more on upper side of the brake fluid pressure supply unit than the cylinder in a vertical direction. Thus, even if fluid leaks from the cylinder, the fluid having leaked can be prevented from entering inside of the electric motor. Thus, the operation of the electric motor is not impaired, whereby the reliability of the brake fluid pressure supply unit can be improved.

Abstract: A brake control device is applied to a brake device that controls a front-wheel braking force and a rear-wheel braking force. The brake control device includes a ratio calculation circuit that calculates a target front and rear braking force distribution ratio based on a target pitch angle, and a brake control circuit that performs a stability control by operating the brake device based on the target front and rear braking force distribution ratio during braking.

Abstract: When it is diagnosed that a braking control device 50 functions normally, a command unit 70f transmits a braking force command value to drive units 60a, 60b, and a command unit 70r transmits the braking force command value to drive units 60c, 60d. Then, the drive units 60a, 60b drives braking mechanisms 30a, 30b according to the command value transmitted by the command unit 70f, and the drive units 60c, 60d drives braking mechanisms 30c, 30d according to the command value transmitted by the command unit 70r. Meanwhile, when it is diagnosed that the braking control device 50 does not function normally, at least one of the command units 70f, 70r executes backup control for compensating for a shortage of a braking force of a vehicle 10 for a braking request, which is caused by the braking control device 50 not functioning normally.

Abstract: A vehicle body speed estimation method applied to a four-wheel drive vehicle includes: acquiring an estimated vehicle body speed based on wheel speeds or a longitudinal acceleration of the vehicle; determining whether an operation condition that includes at least a condition that the estimated vehicle body speed is higher than an operation determination speed is satisfied; performing torque limitation to reduce a torque of a portion of wheels of the vehicle when the operation condition is satisfied; determining whether a stop condition that includes a condition that the estimated vehicle body speed is lower than or equal to a stop determination speed or a condition that a duration of a state where a wheel acceleration of the portion of the wheels is higher than zero is longer than or equal to a set period of time; and stopping the torque limitation when the stop condition is satisfied.

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.
