Embodiment 1

[0052] This embodiment provides a redundant power supply system for a braking system. First, a schematic diagram of a redundant power supply system for a braking system provided by this embodiment is introduced. Refer to figure 1 , the redundant power supply system includes a first power input unit 101, a second power input unit 201, a first brake execution unit 102, a second brake execution unit 202, a redundant execution unit 301; the first power input unit 101 It communicates with the first brake execution unit 102 through the first power supply path 100, and the second power input unit 201 communicates with the second brake execution unit 202 through the second power supply path 200; between the first power supply path 100 and the second power supply path 200 are connected via a redundant branch 300, and a redundant execution unit 301 is arranged on the redundant branch 300 for connecting or disconnecting the redundant branch 300;

[0053] The redundant power supply system...

Embodiment 2

[0095] This embodiment further provides a redundant power supply control method for the brake system on the basis of Embodiment 1, please refer to Figure 11 ,include:

[0096] S100, acquiring voltage signals of the first detection unit and the second detection unit, and judging whether there is an abnormal voltage signal;

[0097] S101. When there is an abnormal voltage signal, acquire a corresponding relationship between the abnormal voltage signal and the first detection unit and the second detection unit;

[0098] S102. According to the corresponding relationship between the abnormal voltage signal and the first detection unit and the second detection unit, and the first detection unit, the second detection unit and the first power supply path and the second power supply path Path correspondence, obtain abnormal power supply path information;

[0099] S103, according to the abnormal power supply path information, connect the redundant branch and the path between the redu...

Abstract

The invention provides a redundant power supply system for a braking system, a redundant power supply control method and a vehicle, and the system comprises a first power input unit which is communicated with a first braking execution unit through a first power supply path; a second power input unit which is communicated with the second brake execution unit through a second power supply path; a first braking execution unit which is used for executing service braking; the second braking execution unit which is used for executing parking braking; a redundancy execution unit which is used for providing a redundancy power supply path when the power supply is abnormal; a power supply detection device which is used for sampling voltage signals; and a control device which is used for acquiring a voltage signal of the power supply detection device, judging whether an abnormal power supply path exists according to the voltage signal, judging whether redundant power supply control is carried out or not according to a judgment result, and judging whether redundant power supply failure exists. According to the redundant power supply system, redundant power supply can be provided when power input is abnormal, a power access is cut off when redundant power supply fails, and the power supply reliability of the braking system is improved.

Description

technical field [0001] The invention relates to the field of vehicle braking control, in particular to a redundant power supply system for a braking system, a redundant power supply control method and a vehicle. Background technique [0002] In the automotive electronic system, especially the electronic system of the brake system, in order to ensure its stability and reliability, the first thing to consider is the high reliability of the power supply system. Therefore, in the design of the automotive electronic braking system, the power supply design needs to have high redundancy to ensure its reliability. [0003] The power supply circuit applied to the vehicle braking system mainly includes two parts, one is to supply power to the executive motor of the driving brake system; the other is to supply power to the parking brake executive motor; in order to improve the reliability of the power supply system of the braking system, The conventional practice is to carry out a sep...
