According to the Tianyancha App, Huawei Technologies Co., Ltd. has obtained a patent authorization for “a braking system for vehicle braking and an autonomous vehicle”. The abstract shows that the present application relates to the technical field of autonomous driving, and the system includes: at least one wheel brake cylinder, a 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; a 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 pumps include a piston and a pump chamber.

Wherein, the pump chamber is connected to the fluid storage tank through the second pipeline; when the piston moves away from the first interface, the pump chamber receives the brake fluid from the fluid storage tank through the second pipeline, and the first interface is the pump chamber and the first pipeline; the pump chamber is connected to at least one brake wheel cylinder through the first pipeline; the piston can move toward the first interface and make the brake fluid in the pump chamber enter the first pipeline to provide brake pressure. The system can provide long-term, high-precision redundant braking.
