Huawei has obtained patent authorization for “a braking system for vehicle braking and an autonomous vehicle”. The information indicates that the present application relates to the technical field of autonomous driving, the system includes at least one wheel brake cylinder, the main brake module, an auxiliary brake module, and an electric linear pump. The system can provide long-term, high-precision redundant braking.
Specifically, the present application relates to the technical field of automatic driving, and in particular, to a braking system for vehicle braking. The system includes: at least one brake wheel cylinder; the main brake module for providing brake pressure to brake the vehicle; an auxiliary brake module including an electric linear pump, a first pipeline, and a second pipeline.
An electric linear pump includes a piston and a pump chamber; wherein the pump chamber is connected to the fluid reservoir through a second pipeline; when the piston moves away from the first interface, the pump chamber receives brake fluid from the fluid reservoir through the second pipeline, and the first interface is the interface between the pump cavity and the first pipeline.
