Electronic power-assisted braking system with redundancy

Abstract

The invention discloses an electronic power-assisted braking system with redundancy, which mainly comprises a body and the like. A brake pipeline A, a brake pipeline B, a brake pipeline C and a brakepipeline D are connected onto the body, an electric power-assisted brake main system is connected with the body through a main oil inlet pipeline, and brake fluid is distributed to the brake pipelineA and the brake pipeline B through the body. The electric power-assisted brake slave system is connected with the body through a slave oil inlet pipeline, and brake fluid is distributed to the brake pipeline C and the brake pipeline D through the body. Electric power-assisted braking of the vehicle is achieved, a brand-new energy recovery mode is adopted, braking energy recovery can be conducted in cooperation with the whole vehicle under the condition that no ESC support exists, the cost is saved, and the applicability of the product is improved; the energy recovery process is controllable, the foot feeling consistency in the braking process under various conditions can be ensured, the requirement for redundant braking is met, and meanwhile the requirement for the large liquid demand of alarge heavy-duty vehicle can be met.

Description

technical field [0001] The invention relates to the field of electronic power-assisted braking systems, in particular to an electronic power-assisted braking system with redundancy. Background technique [0002] QBS refers to Electric Power Braking System. The electric power-assisted braking system of the existing scheme can generally only be applied to small vehicles, and for large vehicles, a large-scale mechanism usually needs to be specially developed, and the degree of safety redundancy is not high enough. This status quo has greatly increased the cost of R&D and manufacturing of large vehicles, which is not conducive to the competitiveness of products. Therefore, there is a need for a new type of electric power-assisted braking system, which can allow the products used on existing small vehicles to be applied to large vehicles. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an ele...
