Huawei is granted a patent for autonomous vehicle braking, which provides long-term redundant braking

Driving China on February 11, 2022, the information shows that on February 11, Huawei Technologies Co., Ltd. obtained a patent authorization for "a braking system and autonomous vehicle for vehicle braking".

The abstract shows that the present application involves the field of automatic driving technology, the system comprises: at least one brake wheel cylinder, the main brake module, the auxiliary brake module, the electric linear pump. The system provides long-term, high-precision redundant braking.

It is understood that the present application involves the field of automatic driving technology, specifically involving a braking system for vehicle braking. The system comprises: at least one brake wheel cylinder; a main brake module for providing brake pressure to brake the vehicle; an auxiliary brake module, comprising an electric linear pump, a first line and a second line; an electric linear pump comprising a piston and a pump cavity; wherein the pump chamber is connected to the reservoir via a second line; when the piston moves away from the first interface, the pump chamber receives brake fluid from the reservoir through a second line, the first interface is the interface between the pump chamber and the first line; the pump cavity is connected to at least one brake wheel cylinder through the first line The piston can be moved towards the first interface and allows the brake fluid in the pump cavity to enter the first line to provide brake pressure. The system can provide long-term, high-precision redundant braking.
