Embodiment 1

[0034] This embodiment provides a millimeter-wave radar active obstacle avoidance method based on vehicle-to-vehicle communication, such as figure 1 shown, including the following steps:

[0035] Select any vehicle on the road as the current vehicle, and obtain the driving data collected by the vehicle-mounted radar of the current vehicle, the driving data including the obstacle information of the driving path;

[0036] Obtain the driving data of all vehicles within the detection range of the current vehicle;

[0037] Fuse the driving data of the current vehicle with the driving data within the detection range of the current vehicle to obtain the position and speed information of all vehicles within the detection range of the current vehicle, and calculate whether there is a vehicle based on the position and speed information of all vehicles within the detection range of the current vehicle possibility of collision;

[0038] If there is a possibility of collision, control th...

Abstract

The invention provides a vehicle to vehicle communication-based millimeter wave radar active obstacle avoidance method. The method comprises the following steps any vehicle on a road is chosen as a current vehicle, driving data collected by a vehicle-borne radar device of the current vehicle is obtained, the driving data includes obstacle information of a driving path, driving data of all vehiclesin a detection range of the current vehicle is obtained, and the driving data of the current vehicle and the driving data in the detection range of the current vehicle are fused to obtain position and speed information of all the vehicles in the detection range of the current vehicle; whether possibility of collision exists is calculated according to the position and speed information of all thevehicles in the detection range of the current vehicle; if yes, the current vehicle is controlled to turn or decelerate to avoid an obstacle. Via the method, total range detection can be realized, possibility of collision is calculated, and obstacle avoidance of the an automobile is controlled; the vehicle is enabled to be high in safety, comfort, stability, real-time performance and timeliness.

Description

technical field [0001] The invention belongs to the field of automobile control, and in particular relates to an active obstacle avoidance method of millimeter-wave radar based on vehicle-vehicle communication. Background technique [0002] In recent years, with the improvement of people's quality of life, the number of car ownership has increased rapidly, which has promoted the vigorous development of transportation and brought convenience to our lives, but there are advantages and disadvantages. The frequency of automobile traffic accidents is increasing day by day. Because the number of traffic accidents accounts for the largest proportion of accidental deaths, traffic safety issues are increasingly attracting people's attention. In recent years, as people pay more and more attention to the safety of automobiles and the development trend of automobile intelligence, millimeter wave radar technology represented by frequency modulated continuous wave (FMCW) technology has be...
