Abstract: A braking control device includes a braking control unit that controls a braking device, a load reduction amount derivation unit that derives a reduction amount of a load input from a vehicle body to a suspension for a second wheel, and an anti-force derivation unit that derives an anti-lift force. The braking control unit performs posture braking processing of adjusting the second braking force so that the difference between the reduction amount of the load and the anti-lift force is less than or equal to a difference determination value, and adjusting the first braking force so that the vehicle braking force becomes the required value.

Abstract: The braking control device includes a control amount derivation unit that derives a target vehicle braking force representing a target value of a vehicle braking force applied, and a braking control unit that controls a regenerative braking device and a frictional braking device based on the target vehicle braking force. When the target vehicle braking force is increased, the braking control unit executes a braking force application process of increasing the frictional braking force applied to the wheel so that such frictional braking force becomes larger than the regenerative braking force applied to the wheel. When the target vehicle braking force is increased, the braking control unit executes a switching process of switching at least a part of the frictional braking force applied to the wheel to the regenerative braking force to increase the regenerative braking force applied to the wheel after execution of the braking force application process.

Abstract: The control device includes a vehicle required braking force acquisition unit that acquires a vehicle required braking force that is a required value of the braking force applied to the vehicle, and a roll control unit that controls the rolling motion of the vehicle by adjusting a distribution ratio of the braking force with respect to a target wheel including at least one of a rear wheel on an inside during turning and a front wheel on an outside during turning of the vehicle when the braking force is applied to the vehicle according to the vehicle required braking force under a situation where the vehicle is turning.

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 braking control device, when stopping a vehicle in a state where a braking force is being applied to the vehicle, executes a reducing control of reducing the braking force corresponding to a braking request before the vehicle stops and executes an increasing control of increasing the braking force corresponding to the braking request before the reducing control in order to suppress vehicle pitching behavior generated when the braking force is applied to the vehicle. The control device sets braking force increase amount in the increasing control based on a difference distance that is a difference between a first distance correlated with a vehicle traveling distance from a reduction start timing when the reducing control is executed until the stopping of the vehicle and a second distance correlated with a vehicle traveling distance from the reduction start timing when the reducing control is not executed until the stopping of the vehicle.

Abstract: A brake control device includes: a decrease determination unit that determines whether a requested braking force for a vehicle is decreasing; and a brake control unit which, on the condition that the decrease determination unit determines that the requested braking force is decreasing during deceleration of the vehicle, executes ratio change decrease control of reducing the braking force of the vehicle according to the decrease of the requested braking force, while making a braking force distribution ratio smaller than a reference braking force distribution ratio. The reference braking force distribution ratio is the braking force distribution ratio at a time point when the requested braking force starts to decrease.
