Embodiment Construction

[0016] Below, refer to Figure 1 to Figure 6 One embodiment of a brake control device for a vehicle will be described.

[0017] exist figure 1 In FIG. 1 , a vehicle including the brake control device 100 according to the present embodiment is shown. like figure 1 As shown, the vehicle includes a drive motor 10 as a driving source of the vehicle, and a plurality (ie, the same number as the number of wheels) of brake mechanisms 14 provided independently for each of the wheels FL, FR, RL, and RR. Each brake mechanism 14 has a wheel cylinder 12 to which brake fluid is supplied. Furthermore, in the brake mechanism 14, when the hydraulic pressure in the wheel cylinder 12, that is, the WC pressure increases, the friction member presses the disc rotor 13 that rotates integrally with the wheels FL, FR, RL, and RR. As a result, frictional braking forces are applied to the wheels FL, FR, RL, and RR.

[0018] figure 1 The drive system of the illustrated vehicle is front-wheel drive,...

Abstract

The vehicle brake control device is applied to a vehicle including an electric parking brake device, a hydraulic brake device, and a regenerative braking device. The brake control device includes a first brake control unit and a second brake control unit. When the parking brake operation is performed while the vehicle is running, the first brake control unit executes the first braking process for increasing the braking force with respect to the vehicle by the operation of the hydraulic brake device. When there is a request to increase the braking force for the vehicle while the first braking process is being performed, the second brake control unit executes the second braking for increasing the braking force for the vehicle by operating the regenerative braking device deal with.

Description

technical field [0001] The invention relates to a brake control device for a vehicle. Background technique [0002] As a parking brake device, there is known an electric parking brake device that applies a braking force corresponding to the driving amount of an electric motor to rear wheels when a driver performs a parking brake operation. [0003] In Patent Document 1, it is described that when the parking brake is operated while the vehicle is running, the brakes for each of the front wheels and the rear wheels are activated by operating the hydraulic brake device instead of actuating the parking brake device. An example of a brake control device with power augmentation. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2013-112017 [0005] While the vehicle is running, even if the hydraulic brake device is activated when the parking brake operation is performed, the actual braking force may not reach the requested braking force requested by the driver as the bra...
