Tianyancha shows that on July 8, the patent for "assisted driving method and device" applied by Huawei Technologies Co., Ltd. was published. The abstract shows that the assisted driving method of this application includes: obtaining multimodal perception information, the multimodal perception information is collected by a variety of sensors arranged on the vehicle; obtaining multiple sets of display information, the display information includes the target area to be displayed and the grid granularity; performing perception prediction based on the multimodal perception information and the multiple sets of display information to obtain multiple occupied grid information, the occupied grid information is used to describe the distribution of obstacles around the vehicle; and displaying multiple occupied grid images on the human-computer interaction interface based on the multiple occupied grid information. This application can not only enhance the driver's panoramic perception ability of obstacles in a large range, but also enhance the driver's refined perception ability of obstacles in a close range. The combination of the two can enhance the driver's perception of the surrounding environment and avoid scratches.
