- the method for establishing a communication connection between vehicles shown in this embodiment is applied to a vehicle-mounted controller, and the vehicle-mounted controller is located in the vehicle.
- the method for establishing a communication connection between the vehicles includes the following steps:
- each on-board controller can find its corresponding target controller. It can be understood that as the vehicle moves, that is, the position of the vehicle changes, its corresponding target controller may change. In other words, each target controller next to a track has its corresponding jurisdiction. Among them, the size of the jurisdiction can be selected and set according to the actual application needs.
- vehicle-mounted controller in each vehicle After the vehicle-mounted controller in each vehicle establishes a communication connection with the target controller in the current jurisdiction, it can receive the target control in the current jurisdiction. Vehicle location broadcast packet sent by the transmitter.
- the vehicle-mounted controller may parse the vehicle location broadcast packet through a preset protocol (such as the RSSP-II protocol, the 802.11 protocol, etc.) to obtain the location information of all vehicles in the area.
- a preset protocol such as the RSSP-II protocol, the 802.11 protocol, etc.
- the vehicle-mounted controller can accurately obtain the specific location information of each vehicle in this jurisdiction. For example, vehicle A is at position X, vehicle B is at position Y, etc., so it can be determined how many meters vehicle A is from the host vehicle, and how many meters vehicle B is from the host vehicle.
- a target vehicle that satisfies the communication conditions can be filtered.
- the preset distance threshold is 50 meters, that is, when the host vehicle needs to establish communication with the vehicle within 50 meters and within the vehicle, so that the host vehicle is the center, the host vehicle is 50 meters away and the The vehicles inside are vehicle C and vehicle D respectively, so that the target vehicle is determined to be vehicle C and vehicle D.
- the preset distance threshold can be selected and set according to actual application requirements.
- the preset distance threshold is determined by the processing cycle of the vehicle controller and the communication time between each vehicle.
- the processing cycle of the vehicle controller is 10ms
- the communication time between each vehicle is 1ms. That is to say, the vehicle-mounted controller can only communicate with 10 vehicles in a processing cycle, that is, this preset distance threshold needs to be set at a distance including the target vehicle of 10 vehicles or less.
- the difference between the preset distance threshold and the distance authorized for vehicle movement is greater than the preset threshold. It can be understood that when the vehicle travels, there will also be a change in the communication area range that results in the need to establish communication with vehicles entering the area and disconnect communication with vehicles leaving the area, but due to the preset distance threshold and vehicle movement authorization The difference in the distance of the vehicle is greater than a preset threshold value, and will not affect the calculation of the distance for vehicle movement authorization.
- the preset distance threshold is 10km, and the vehicle's authorized movement distance is generally several hundred meters in the forward direction. When the vehicle is moving forward, communication has been established with the vehicle, there is no delay effect, and the operation efficiency is improved.
