Document Type and Number:
WIPO Patent Application WO/2022/028519
Kind Code:
A1
Abstract:
A bypass energy accumulating device for an electronically controlled hydraulic braking system, relating to the field of new energy automobile braking systems. A first pipeline and a second pipeline are provided at an outlet end of a brake master cylinder (1), a fourth isolation valve (5) for controlling the on/off of the first pipeline is connected to the other end of the first pipeline, and a fifth isolation valve (6) for controlling the on/off of the second pipeline is connected to the other end of the second pipeline; a first branch is connected to the first pipeline, the other end of the first branch is communicated with an energy accumulator (7), and a first inflow valve (2) for controlling the on/off of the first branch is connected to the first branch; a second branch is further connected to the second pipeline, the other end of the second branch is also communicated with the energy accumulator (7), and a second inflow valve (3) for controlling the on/off of the second branch is connected to the second branch; a third branch is further connected to the energy accumulator (7), and the other end of the third branch is communicated with the second pipeline. The effects that the energy consumption can be reduced, the foot feeling can be well controlled, and the comfortability and safety of the product are improved are achieved.
