　　It is reported that "Autoware" is the world's first "integrated" open source software for self-driving cars.

　　2. Disclosure of a patent related to an automatic driving method

　　On July 16, Huawei Technologies Co., Ltd. published a patent for "An Autonomous Driving Method, Related Equipment, and Computer-readable Storage Medium", with the publication number CN113128303A.

　　The patent abstract shows that the application provides an automatic driving method, related equipment, and computer-readable storage medium. The method is applied to a cloud server. The implementation of this application can reduce the risk of automatic driving.

　　The specific methods include:

　　(1) Receive vehicle attribute information reported by the target vehicle and the travel information of the target vehicle, where the vehicle attribute information of the target vehicle is used to generate an automatic driving strategy;

　　(2) Obtain the layer information of the first road segment driven by the target vehicle in the automatic driving strategy layer according to the trip information;

　　(3) Acquire the first driving strategy according to the layer information of the first road section and the vehicle attribute information of the target vehicle;

　　(4) Send the first driving strategy to the target vehicle.

　　3, "Autonomous driving navigation method" related patents were authorized

　　On June 1, Huawei Technologies Co., Ltd. was granted a patent for "Autonomous Driving Navigation Method, Device, System, Vehicle Terminal and Server", the publication number is CN108027242B.

　　The patent summary shows that the present invention is an automatic driving navigation method, device, system, vehicle terminal and server. It adopts satellite differential positioning technology based on wireless network assistance to realize automatic driving navigation in all weather and road conditions, and the positioning accuracy does not need to depend on With 3D high-precision maps, the adaptability and reliability of the solution are significantly increased.

　　The patent abstract also shows that the method of the present invention includes:

　　(1) The wireless base station in the wireless network sends the differential positioning correction number to the vehicle-mounted terminal (202);

　　(2) The vehicle terminal obtains the satellite positioning data of the vehicle, receives the differential positioning correction data from the wireless base station of the wireless network, and uses the differential positioning correction number to correct the satellite positioning data to obtain the high-precision position of the vehicle. Location (204);

　　(3) The server receives the high-precision location from the vehicle-mounted terminal, determines the lane-level planned driving path based on the high-precision location and combined with high-precision map information, and the server sends the lane-level planned driving path to the vehicle terminal (206);

　　(4) The vehicle-mounted terminal receives the lane-level planning driving path from the server, and according to the acquired high-precision position, controls the vehicle to automatically drive according to the lane-level planning driving path (208).

　　4. Patent related to "self-learning method of automatic driving system"

　　Huawei Technology Co., Ltd. published a patent "Self-learning method, device, equipment and storage medium of automatic driving system", the patent publication number is CN112805199A, and the publication date is May 14.

　　It is understood that the patent is a method and device for adaptively optimizing the automatic driving system, which relates to the field of automatic driving technology. It solves the problem of conflict between the driving behavior of the vehicle under the control of the automatic driving system and the driving intention of the driver. It can be applied In smart cars and connected cars. It can ensure that the self-learning data of the automatic driving system conforms to the design operating domain, traffic rules and safe driving rules of the vehicle, so that the automatic driving system parameters obtained by self-learning can not only conform to the user's driving habits, but also improve the safety and user experience .

　　The patent summary shows that the specific implementation of the patent is: obtain driving data (S201); remove abnormal data in the driving data to obtain the data to be processed (S202); select the driving parameters to be learned based on the data to be processed, and follow the driving parameters The corresponding calculation rule calculates the data to be processed to obtain the learning result of the driving parameter (S203), and the learning result is used to instruct the automatic driving system to set the driving parameter according to the learning result during the automatic driving journey.

　　It is reported that Huawei's autonomous driving ADS system has 3 96-line car-gauge lidars, 6 millimeter wave radars, 12 cameras, 13 ultrasonic radars, and is equipped with a Huawei chip with a computing power of up to 352 Tops, which can meet the needs of automatic urban scenes. Driving, realize functions such as "valet parking + remote call".
