Embodiment 1

[0035] This embodiment discloses an automatic driving control method at a special-shaped intersection, including the following steps:

[0036] S1. Obtain the avoidance zone in front of the vehicle;

[0037] S2. Obtain the travel map of the vehicle, the travel map takes the vehicle as the coordinate center and is located in front of the vehicle;

[0038] S3. Detect whether there is an overlapping area between the traveling map and the avoidance area;

[0039] S4. When an overlapping area is detected in step S3, detect whether there is a moving object in the overlapping area;

[0040] S5. Control whether the vehicle enters the avoidance area according to the detection result of step S4.

[0041] Obtain the avoidance area and travel map in front of the vehicle, and detect whether there is an overlapping area between the two. When there is an overlapping area between the two, detect whether there is a moving object in the overlapping area, and then control the movement of the ve...

Embodiment 2

[0043] Such as figure 2 and image 3 As shown, the present embodiment discloses an automatic driving control method at a special-shaped intersection, including the following steps:

[0044] S1. Obtain the avoidance area 3 in front of the vehicle 2, and obtain the stop line in front of the vehicle 2 at the same time;

[0045] S2. Obtain the travel map 4 of the vehicle 2. The travel map 4 takes the vehicle 2 as the coordinate center and is located in front of the vehicle 2; wherein the travel map 4 and the avoidance area 3 have the same shape and are both rectangular; and the travel map 4 is slightly larger than The area of ​​the avoidance zone 3.

[0046] S3. Detect whether there is an overlapping area between the traveling map 4 and the avoidance area 3;

[0047] S4. When an overlapping area is detected in step S3, detect whether there is a moving object 1 in the overlapping area; the moving object 1 mainly refers to pedestrians, animals, other vehicles 2, bicycles or elec...

Abstract

The invention relates to the technical field of automatic driving, and particularly relates to an automatic driving control method of a special-shaped road intersection, and a vehicle. The automatic driving control method of the special-shaped road intersection comprises the following steps: S1, acquiring an avoidance region in front of the vehicle; S2, acquiring a marching map of the vehicle, wherein the vehicle is taken as a coordinate center of the marching map, and the marching map is located in front of the vehicle; S3, detecting whether the marching map is overlapped with the avoidance region; S4, when an overlapped region is detected in the step S3, detecting whether a moving object is in the overlapped region; S5, according to the detection result of the step S4, controlling the vehicle to enter into the avoidance region or not. The avoidance region and the marking map in front of the vehicle are acquired, and whether the avoidance region and the marching map are overlapped isdetected, when the overlapped region is formed by the avoidance region and the marching map, whether the moving object exists in the overlapped region is detected, and then, operation of the vehicle is controlled according to whether the moving object exists in the overlapped region, thus, situations of the special-shaped road intersection and vehicles arising can be accurately and quickly judged,safe driving can be realized.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to an automatic driving method and a vehicle at a special-shaped intersection. Background technique [0002] With the advent of 5G technology, unmanned autonomous driving is gradually becoming possible. Unmanned driving requires high-precision maps to accurately judge and compare road conditions, but the penetration rate of high-precision maps is still very low, and the complex heterogeneous road information is even rarer. but if figure 1 As shown, the unmanned vehicle 20 needs to make accurate and fast judgments on the situation of the irregular intersection and the vehicles appearing at the irregular intersection, so as to avoid the occurrence of safety accidents and ensure safe driving. When the unmanned vehicle 20 is driving to a special-shaped intersection, the opponent's first vehicle 10 is driving. According to the traffic regulation "turn and go straight", if the...
