Embodiment Construction

[0065] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] One of the core concepts of the embodiments of the present invention is to determine the geographic range of each vehicle, and allocate different radar communication time slots to multiple target vehicles within the same target geographic range, so as to ensure that the radars of vehicles with similar distances are not separated from each other. They will interfere with each other to ensure that the vehicle radar has a good detection ability.

[0067] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a method for allocating communication time slots according to the present invention. The method is applied to a server, and may specifically include the following steps:

[0068] Step 101, receiving...

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...
