Automobile automatic parking method based on 5G communication mode

Abstract

The invention discloses an automobile automatic parking method based on a 5G communication mode. The automobile automatic parking method comprises the steps that space information around an automobilebody and posture information of the automobile are collected through a sensor installed on the automobile body; information data is packaged and sent to a cloud server through a 5G communication technology; the cloud server firstly judges whether the obtained data meets a parking requirement or not, and then judges whether a surrounding environment is dynamic or static; and if the surrounding environment is static, an optimal parking path is acquired by the cloud server through the collected data, and then an optimal parking path instruction and a parking instruction are sent to the automobile by the cloud server through 5G communication so that the automobile completes an automatic parking process. Based on a cloud 5G communication mode, real-time performance of data sending during communication can be guaranteed; and the cloud server collects a large amount of parking information so that a parking algorithm can be optimized, the optimal parking path can be obtained, and accuracy canalso be ensured.

Description

technical field [0001] The invention relates to a method for automatic parking of a car in a 5G communication mode, relates to the fields of 5G communication and automatic driving of a car, and has a great auxiliary effect on liberating drivers from parking difficulties. [0002] technical background [0003] The increase in travel demand of residents and the expansion of travel distance stimulate the growth of public demand for car use. The urban population is large and the land area is small, which makes the problem of "difficult parking" a problem that plagues people's daily travel. Limited parking space, complex and changeable parking environment, and uneven levels of drivers all increase the difficulty of manual parking. The development of artificial intelligence control technology and the large-scale use of various high-precision sensors such as lidar, GPS, and inertial navigators have led to the emergence of various intelligent driving assistance systems (ADAS). And ...

Problems solved by technology

[0004] At present, the application of the automatic parking method for industrial application is generally integrated in the ADAS (Advanced Driver Assistance System) of the vehicle, such as figure 1 As shown, the relevant parking algorithm will be integrated into the car system. When parking is required, the vehicle body sensor will be used to collect information, and the path will be calculated and planned by the processing unit ECU. This method can meet most parking scenarios, but Compared with the method of passing through the cloud server under 5G communication, the disadvantage is that the parking algorithm cannot be well optimized, resulting in an unsatisfactory parking path, which may cause the effective parking space to be unable to perform parking operations
