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 vehicle which adopts a control device as a braking control device includes a sensor that acquires a rotation angle of a wheel. The control device includes a first distance calculation unit, a second distance calculation unit, and a braking control unit. The first distance calculation unit sets a braking force corresponding to a braking operation member operation amount as a reference braking force, estimates vehicle longitudinal acceleration based on the reference braking force, and calculates a braking force reference distance estimating a moving distance until the vehicle stops based on the longitudinal acceleration. The second distance calculation unit calculates a wheel reference distance estimating the vehicle moving distance based on a detection signal of the sensor and a wheel diameter. The braking control unit executes feedback control for controlling the vehicle braking force so that a difference between the braking force reference distance and the wheel reference distance decreases.

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 motion manager that is mounted on a vehicle includes a processor and a memory. The processor receives a motion request that corresponds to an application from individual applications. The processor arbitrates the received motion request. The processor generates, based on an arbitration result, an instruction value of an operation request to be output to a brake control unit. The memory stores, in advance, type information of an actuator to be controlled by the brake control unit. The processor generates the instruction value of the operation request using the type information.
