Problems solved by technology

[0020] However, the fail-safe device shown in Fig. 5 still needs to use at least two solenoid valves 207, 208, so the competitiveness is still poor in terms of cost, especially when the two solenoid valves 207, 208 are respectively installed in different On-line, and these lines are also connected with connectors, so there are certain limitations in simplifying its composition

Embodiment Construction

[0043] Below, the embodiments of the present invention will be described in detail in conjunction with the accompanying drawings. These embodiments are only an example of the present invention. Anyone with general knowledge in the technical field to which the present invention belongs can realize it in various different forms. Therefore, The invention is not limited to the embodiments described here.

[0044] FIG. 1 shows the composition of an electric power-assisted braking device utilizing a fail-safe safety valve according to this embodiment.

[0045] As shown in the figure, the electric power-assisted braking device is composed of ECU1 connected to the pedal sensor 3 that detects the dynamics of the pedal 2, the sub-cylinder 5 that generates brake oil pressure due to the stroke change of the pedal 2, and the electric booster 7 driven by the control of the ECU1. The master cylinder 8 that generates the brake oil pressure, the fail-safe means 10 that supplies the brake oil p...

Abstract

The invention relates to an electric booster braking device for regenerative braking, which comprises a sub-cylinder (5) hydraulic chamber that generates brake oil pressure through the stroke change of a pedal (2) and an electric booster (7) driven by an ECU (1). The hydraulic chambers of the master cylinder (8) that generate brake oil pressure are connected to each other by a hydraulic linkage line (11), and there is also a solenoid valve (12) installed on the hydraulic linkage line (11) that is switched by the ECU (1). ) to supply the brake oil pressure of the sub-cylinder (5) to the master cylinder (8), so as to provide brake oil pressure to the front wheel and the rear wheel at the same time, and can always generate a braking force of more than 0.4g, Not only can fail-safe safety be realized stably, but even the composition of the fail-safe device only uses one electromagnetic valve (12), which has the characteristics of greatly reducing cost and weight.

Description

technical field [0001] The present invention relates to an electric power-assisted braking device, in particular to an electric power-assisted braking device which can realize fail-safe (Fail-Safe) by using an electromagnetic valve. Background technique [0002] Generally speaking, hybrid vehicles, fuel cell vehicles, or electric vehicles are vehicles that can perform regenerative braking, and the fuel economy of vehicles can be improved through regenerative braking (Regenerative Brake). [0003] A braking device that performs regenerative braking as described above is generally called a braking device for regenerative braking. [0004] The brake device for regenerative braking includes a main master cylinder that uses an electric booster (motor) to form oil pressure and an auxiliary master cylinder that is activated by a pedal to form oil pressure together with it. The main master cylinder and the auxiliary master cylinder Supplement each other's hydraulic pressure to achi...
