Abstract

The invention is suitable for the technical field of vehicle-mounted radars, and provides a radar detection method, device and equipment for vehicle, and a storage medium. The method comprises the steps: starting a 77GHz millimeter-wave radar sensor on a vehicle of a user when a radar detection request is detected; collecting the surrounding information of the vehicle of the user through the 77GHzmillimeter-wave radar sensor, and transmitting the drive information of the vehicle of the user to a surrounding vehicle; processing the surrounding information of the vehicle of the user through a radar signal processor on the vehicle of the user, so as to obtain the relative distance and relative speed of the vehicle of the user and a surrounding target object; giving a driving prompt to the user according to the relative distance and relative speed, thereby effectively reducing the hardware size of the radar detection device, and improving the convenience of radar detection of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of vehicle radar, and in particular relates to a vehicle radar detection method, device, equipment and storage medium. Background technique [0002] Nowadays, autopilot technology is developing rapidly, and radar technology is an essential key technology in autopilot technology. In autonomous driving technology, 24GHz millimeter-wave radar and 77GHz millimeter-wave radar are often used together. Among them, 24GHz millimeter-wave radar is usually used to detect objects in the short range of the vehicle, including other vehicles and pedestrians in front of and behind the vehicle, and 77GHz millimeter-wave radar is used To detect objects in the long-distance forward range, compared with the 24GHz millimeter radar, the 77GHz millimeter radar has a narrower target detection range and a longer distance. [0003] However, the 24GHz millimeter-wave radar receiving and transmitting devices are subject to technical r...
