Problems solved by technology
[0004] However, it is difficult for the DSRC-derived radar function scheme to detect the position and speed of the target in the environment more accurately than the current vehicle-mounted radar sensor, and the communication short message transmission process has low efficiency and high delay, which is difficult to meet the needs of advanced assisted driving or unmanned vehicles. Driving requirements, how to better realize the vehicle's radar communication integration function is still a severe technical challenge

The present application provides a method for realizing vehicle radar communication integration, related equipment and a system. The method includes: the radar device of the first vehicle obtains the first communication message; modulates the first communication message into a first carrier signal, and the working frequency of the first carrier signal is in the working frequency band of the radar device; radar signal, and send the first carrier signal to the second vehicle in the time gap between sending the radar signal of the current cycle and sending the radar signal of the next cycle. By implementing the embodiment of the present invention, the vehicle can not only perform better radar detection, but also interact with other vehicles through communication short messages, improve the efficiency of communication short message delivery, reduce communication delay, and meet the requirements of advanced assisted driving or unmanned driving.
Description
technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a method for realizing vehicle radar communication integration, related equipment and a system. Background technique [0002] During the driving process of the vehicle, the targets in the environment (such as other motor vehicles, non-motor vehicles, pedestrians, etc.) are all non-cooperative targets relative to the vehicle, and non-cooperative targets usually do not actively provide their own motion information (such as motion status) to the vehicle. , spatial location, etc.). If the vehicle can simultaneously acquire the movement information of the target in the environment (such as radar detection) and realize the short message interaction with other vehicles, it will be beneficial to realize the perception, positioning and route planning of the environment for advanced assisted driving or unmanned driving. In this paper, the function of both radar detecti...
