Abstract: A braking force control apparatus includes a fluid pressure generation mechanism, a braking mechanism and an electric control unit. The fluid pressure generation mechanism causes a braking mechanism to generate a required fluid pressure. The braking mechanism applies a braking force depending on the required fluid pressure to each of wheels through the pressing of a braking member against a rotating rotary member due to the required fluid pressure. The electronic control unit performs, when the required fluid pressure is generated and a vehicle state shifts from a running state to a stopped state at a first time point, stop-time boost control to boost the required fluid pressure at and after the first time point.

Abstract: Vibrations of a hydraulic pressure in an upstream portion due to operations of a slip control device during anti-lock control are transmitted to a control pressure chamber via a pressurizing piston of a master cylinder and a control piston of a regulator. During anti-lock control, in contrast, a pressure-increase linear valve and a pressure-reduction linear valve are opened, allowing change in volume of the control pressure chamber, resulting in reduction in stiffness. This reduction suppresses vibrations of a hydraulic pressure in the control pressure chamber, resulting in suppression of vibrations of a hydraulic pressure in a front pressure chamber. As a result, it is possible to reduce the lowering in control accuracy for a hydraulic pressure in a brake cylinder in anti-lock control using the hydraulic pressure in the front pressure chamber, which can well avoid a long braking distance.

Abstract: A control device for a vehicle includes one or more processors configured to: perform feedback control on an acceleration of the vehicle by controlling a driving force of an internal combustion engine mounted on the vehicle based on a difference between a requested acceleration of the vehicle from an application and an actual acceleration of the vehicle; calculate a first predicted acceleration that is a predicted acceleration of the vehicle on an assumption that the internal combustion engine is controlled into a fuel-cut state; and control the internal combustion engine into the fuel-cut state without performing the feedback control when a coasting condition that is predetermined is satisfied and the first predicted acceleration is equal to or higher than a lower limit value that is predetermined as a negative value.
