Communication time slot allocation method and device, and server

Abstract

The embodiment of the invention provides a communication time slot allocation method and device and a server. The method comprises the following steps: receiving driving associated information sent bya plurality of vehicles; separately determining the geographical range of each vehicle by adopting the driving associated information; and allocating different radar communication time slots to the plurality of target vehicles in the same target geographical range. According to the communication time slot distribution method provided by the embodiment of the invention, the vehicles with close distances can send and receive the radar signals based on different radar communication time slots, the radar signal interference between the vehicles with close distances is reduced, and the good detection capability of the radar is ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication time slot allocation method, a communication time slot allocation device, and a server. Background technique [0002] With the development of driver assistance technology, more and more vehicles are equipped with radar to measure the speed of the vehicle, the distance between vehicles, etc., to provide assistance to the driver in driving the vehicle. Generally speaking, vehicle radar usually uses 24GHz and 76GHz to 81GHz spectrum. With the increase of the number of radars on the road, mutual interference between radars of the same model and modulation is likely to occur, which affects the detection capability of the radar. [0003] Especially for radars using frequency-modulated continuous wave (FMCW) technology, since they continuously transmit frequency-modulated signals, radars using frequency-modulated continuous wave technology are more likely to interf...

Problems solved by technology

Generally speaking, vehicle radar usually uses 24GHz and 76GHz to 81GHz spectrum. With the increase of the number of radars on the road, mutual interference between radars of the same model and modulation is likely to occur, which affects the detection capability of the radar.

[0003] Especially for radars using frequency-modulated continuous wave (FMCW) technology, because they continuously transmit frequency-modulated signals, radars using frequency-modulated continuous wave technology are more likely to interfere with each other, and it is easier to affect the detection capability of the radar.
