Different traffic participants can be identified by identification ID, such as vehicles and roadside facilities, while the same type of traffic participants, such as vehicles, cannot be identified by identification ID, so the self-vehicle will receive a large number of traffic signals on the road. The information of other vehicles, only some of which are useful information related to the own vehicle, and the rest are irrelevant information, and the information is redundant, occupying communication resources

Embodiment Construction
[0029] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0030] This application discloses a data screening method for intelligent networked vehicles, please refer to figure 1 As shown in the flowchart, the method mainly includes the following steps:
[0031] First of all, before using this method, the establishment of a road section database that needs to be divided into road sections is usually preferred, mainly including the following two parts:
[0032] (1) Road sections are divided according to the roads that vehicles actually drive. The basis for division includes but is not limited to: dividing road sections according to natural intersections, which is mainly applicable to areas with dense intersections of urban roads. Alternatively, road sections are divided according to road characteristic points such as entrances and exits, which is mainly applicable to express lanes at intersections of...

The invention discloses a data screening method for an intelligent networked automobile, and relates to the field of intelligent networked automobiles. In the method, the first vehicle determines a corresponding position screening condition according to the driving states of the preset driving path at the previous moment and the next moment; screening out second vehicle information which meets a position screening condition and is closest to the first vehicle coordinate as target information according to a second vehicle yaw angle and a second vehicle coordinate in all the received second vehicle information, reserving the target information and filtering out other second vehicle information; according to the method, useful information related to the vehicle can be effectively filtered andscreened out, irrelevant information is removed, information redundancy is avoided, and the effective information extraction efficiency is high.
Description
technical field [0001] The invention relates to the field of intelligent networked vehicles, in particular to a data screening method for intelligent networked vehicles. Background technique [0002] It is an important direction for the development of intelligent transportation to achieve the goal of safer, more efficient and green driving by establishing extensive data connections between vehicles. With the development of vehicle intelligence and networking, more and more vehicles are connected to the network. The existing vehicle networking data transmission method is broadcast transmission, that is, the vehicle will receive all vehicles, roadside facilities, and other traffic participants within the communication range. information sent by the Different traffic participants can be identified by identification ID, such as vehicles and roadside facilities, while the same type of traffic participants, such as vehicles, cannot be identified by identification ID, so the self-...
