Control method of automatic driving vehicle

Abstract

The invention relates to a control method of an automatic driving vehicle. The method comprises the following steps of when a to-be-driven road section of the vehicle is confirmed to contain a bridgeopening, judging a lane where the vehicle is positioned, and taking the corresponding measures, such as lane changing, deceleration, etc., in advance according to the condition of the lane, so that the vehicle can safely and stably pass through the road section.

Description

technical field [0001] The invention belongs to the field of vehicle engineering, and in particular relates to a control method for an automatic driving vehicle passing through a bridge opening. Background technique [0002] On the auxiliary roads of ring roads, elevated roads, and expressways in some cities, bridge openings (or called bridge openings) are provided, and this opening is provided for the vehicle to realize turning around to the opposite lane on the auxiliary roads. For vehicles going straight or turning through intersections or T-junctions, there are traffic lights as traffic instructions, but for vehicles making U-turns on auxiliary roads, there are often no special traffic lights, as long as they do not affect the normal driving of other vehicles. can pass. [0003] According to traffic rules, the right of way of vehicles going straight is higher than the right of way of vehicles turning around on the auxiliary road. Therefore, the normal straight-going ve...

Problems solved by technology

However, vehicle drivers who are not experienced enough or do not obey traffic rules or pedestrians, electric vehicles or bicycles often do not consider the distance and speed of straight vehicles when passing, which leads to the need for straight vehicles to slow down, and even sudden braking, Collision etc.

In addition, because the light inside the bridge opening is very dark, it is more difficult for vehicles going straight to observe other traffic participants in the bridge opening, which exacerbates the degree of unsafety

[0004] Although vehicle autonomous driving technology has been gradually put into practical use, there is currently no solution for this road condition

The current vehicles with automatic driving function have been equipped with anti-collision function, but due to the visual blind spot at the bridge opening to the oncoming straight vehicles, it is difficult to identify in advance, and sudden braking is prone to occur when passing the bridge opening, even if it can be avoided Collisions can also lead to reduced comfort
