Problems solved by technology

If both volumes decrease due to thermal relaxation, the braking force may decrease because the pressing force decreases even if the requested hydraulic pressure remains constant.
As a result, there is a possibility that the stopped vehicle will roll away against the driver's intention
[0005] In addition to this, there is a possibility that, when the vehicle is stopped due to the driver's own brake pedal operation, the driver accidentally loosens the brake pedal's depressing operation force (depression force) (hereinafter, Also known as "pedaling loose"), resulting in the vehicle rolling

Embodiment Construction

[0026] Such as figure 1 As shown, the braking force control device (hereinafter also referred to as "this embodiment device") 10 according to the embodiment of the present invention constitutes an electronically controlled braking system (ECB) for a vehicle, and controls four The braking force imparted by the wheels. The embodiment device 10 is mounted, for example, on a hybrid vehicle including an electric motor and an internal combustion engine as driving sources. In such a hybrid vehicle, regenerative braking for braking the vehicle by regenerating kinetic energy of the vehicle into electric energy and hydraulic braking according to the present embodiment 10 can be used for braking the vehicle. A vehicle equipped with this embodiment device 10 according to the present embodiment can execute brake regeneration cooperative control for generating a desired braking force using both regenerative braking and hydraulic braking.

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.

Description

technical field [0001] The invention relates to a braking force control device. Background technique [0002] Conventionally, there is known a braking device that applies a braking force to each wheel of a vehicle. The braking device is provided with: a hydraulic pressure generating mechanism that, when there is a braking request, generates hydraulic pressure related to the requested braking force corresponding to the braking request as the requested hydraulic pressure; and a braking mechanism that is provided on each wheel and will depend on the request A hydraulic braking force is applied to each of the aforementioned wheels (see, for example, JP 2015-182639 ). [0003] The braking mechanism includes: a rotating member such as a disc or a drum, which rotates together with a wheel; and a braking member such as a brake pad or a shoe, which can be brought into contact with the rotating member. Such a brake mechanism uses the hydraulic pressure generated by the hydraulic pre...
