Embodiment 1

[0098] Embodiment 1: When the vehicle has a high-precision map, the road width data is obtained from the map data, and the width of the backward road is searched to obtain the width of the road behind the vehicle.

Embodiment 2

[0099] Embodiment 2: When the vehicle does not have a high-precision map, the vehicle itself continuously measures the width of the road, and in combination with the map route, continuously records the route for a certain period of time (for example, 30 minutes) or within a certain distance range (for example, within 800 meters). road width data. The recorded data includes the driving route map, the GPS position of the route where the width changes, and the road width value, so as to obtain the width of the road behind the vehicle from the recorded data.

[0100] S202. Based on the width of the road behind, it is judged whether there is a possible meeting point on the road behind.

[0101] Compare the road width L with the sum C1+C2 of the widths of two-way vehicles, if L-C1-C2 is greater than the safe width.

[0102] S203, if it exists, calculate the distance between the position of the possible meeting point and the position of the own vehicle;

[0103] S204, obtaining the...

Abstract

The invention discloses an unmanned vehicle avoidance method and an unmanned vehicle avoidance device and belongs to the unmanned driving technical field. The method comprises the following steps that: a detection result of a road condition is obtained; when the detection result does not satisfy a preset vehicle meeting condition, avoidance information is generated according to the detection result and a preset avoidance rule, wherein the avoidance information contains the avoidance rule; and the avoidance information is sent to at least one surrounding vehicle, so that the at least one surrounding vehicle performs vehicle meeting according to the avoidance information. According to the unmanned vehicle avoidance method and the unmanned vehicle avoidance device of the invention, whether aroad can satisfy the condition of vehicle meeting can be judged by means of road condition recognition; and when the road does not satisfy the condition of vehicle meeting, an automatic negotiation mechanism is provided, so that vehicles which will meet each other can avoid each other through negotiation.

Description

technical field [0001] The invention relates to the technical field of unmanned driving, in particular to an avoidance method, device and electronic equipment for an unmanned vehicle. Background technique [0002] Driverless car is a kind of smart car, also known as wheeled mobile robot, which mainly relies on the computer system-based smart driver in the car to achieve the goal of driverless driving. [0003] There are two scenarios for unmanned vehicle avoidance. One is that driving errors lead to possible frontal collisions or rear-end collisions, and the other is that the road itself is not wide enough to meet the meeting of vehicles on both sides or there are obstacles on the road. The original road narrowed so that cars could not pass. [0004] Since the development of unmanned driving technology is still in the experimental stage, it has not been put into use. And in the prior art, most unmanned driving technologies are to study the problem of how to prevent vehicle...
