Embodiment 1

[0044] refer to figure 1 As shown, the present invention provides a lane recognition and lane keeping method, comprising the following steps:

[0045] S1: Identify the relevant lanes in the road where the vehicle is located, and identify the vehicle information of the adjacent vehicles of the vehicle on the relevant lanes.

[0046] The "relevant lane" mentioned here refers to the lane related to the driving demand according to the type of the road where the vehicle is located and the position of the vehicle on the road. For example, in this embodiment, the vehicle is currently in a road type with at least three lanes, and the position of the vehicle in the road is the middle lane (not the sidemost lanes on both sides), and the relevant lane is the lane where the vehicle is currently located. The lane to the left of the vehicle and the lane to the right of the vehicle. In other cases, such as a vehicle driving on a two-lane road and driving along the right side, the relevant ...

Embodiment 2

[0114] The present invention also provides a lane identification and lane keeping terminal equipment, such as Figure 6 As shown, it includes a memory, a processor and a bus, the memory stores at least one program, and the program is executed by the processor to implement the lane recognition and lane keeping method according to Embodiment 1 of the present invention.

[0115] The processor includes one or more processing cores, the processor is connected to the memory through a bus, and the memory is used to store program instructions. When the processor executes the program instructions in the memory, the lane recognition and lane keeping described in Embodiment 1 of the present invention are realized. method.

Abstract

The invention relates to a lane recognition and lane keeping method and terminal equipment. The lane recognition and lane keeping method comprises the following steps of S1, recognizing a related lanein a road of a vehicle and recognizing vehicle information of an adjacent vehicle of the vehicle on the related lane; S2, judging a safety grade of the related lane of the adjacent vehicle accordingto the vehicle information of the adjacent vehicle, wherein the safety grade comprises safety and danger; S3, judging the type of a forward lane of the vehicle according to the vehicle information ofthe adjacent vehicle, wherein the type comprises a straight lane and a curve; and S4, according to the safety grade of the related lane and the type of the forward lane, controlling the vehicle to runaccording to a corresponding target steering angle. According to the lane recognition and lane keeping method, by recognizing the types of the adjacent lane and the forward lane and combining the adjacent vehicle on the adjacent lane, corresponding vehicle controls are carried out for different road conditions so that the vehicle running is safer and more comfortable.

Description

technical field [0001] The invention relates to the technical field of lane recognition, in particular to a lane recognition and lane keeping method and a terminal device. Background technique [0002] Lane keeping is a very important research aspect of autonomous vehicles. Lane keeping is to keep the vehicle in the current lane. The function of lane keeping in automatic driving plays a vital role in reducing the occurrence of traffic accidents. With the development of vehicle intelligence and automatic driving technology, lane keeping technology has received more and more attention. For self-driving vehicles, the driver's burden is relieved by completely taking over the driving task, and its lane keeping system needs to control the vehicle to drive in the lane. [0003] The patent for invention with the publication number CN106515730A "Lane Keeping Assist System and Its Method" discloses a lane keeping assist system that can ensure reliable lane recognition even on congest...
