Although the news about Huawei's car manufacturing has appeared many times, Huawei's response has also emphasized that Huawei's positioning is not to directly build cars, but to become a supplier of smart auto parts and help car companies build cars.
With the gradual advancement of Huawei's plan, there are also automotive-related technology patents that appear in the exposure.
The latest news shows that a patent under Huawei's umbrella called "a braking system and autonomous vehicle for vehicle braking" was recently exposed.
The applicant (patent right) is Huawei Technologies Co., Ltd., the application date is July 10, 2020, and the date of the authorization announcement is February 11, 2022.
The patent abstract shows that the present application relates to the field of autonomous driving technology, specifically a braking system for vehicle braking. The system provides long-term, high-precision redundant braking.
The system includes: at least one brake wheel cylinder; a main brake module to provide brake pressure to brake the vehicle; an auxiliary brake module, including an electric linear pump, a first line, and a second line; and an electric linear pump consisting of a piston and a pump cavity.
Wherein, the pump cavity is connected to the reservoir through the second line; when the piston moves away from the first interface, the pump cavity receives brake fluid from the reservoir through the second line, and the first interface is the interface between the pump cavity and the first line; the pump cavity is connected to at least one brake wheel cylinder through the first line; the piston may move towards the first interface and make the brake fluid in the pump cavity enter the first line to provide brake pressure.
In addition to vehicle-related, Huawei has also exposed a lot of patent information in other aspects in recent days.
This week, Huawei's patent, dubbed "augmented reality or mixed reality headsets," was also officially announced. The abstract shows a headset for wearing on a user's head, providing virtual reality, augmented reality, and mixed reality.
In addition, Huawei has also published a patent for "blind guidance methods, devices, and wearable devices".
The abstract shows that the present application is suitable for the field of blind guidance technology, providing a blind guidance method, device and wearable device.
Even if the posture of the wearable device changes, it can still determine the orientation information of the obstacle relative to the wearer according to the first orientation information of the wearable device and the wearer, so that more accurate obstacle position information can be obtained, and the wearable device does not need to be held, which can free the hands and improve the convenience of the user.
