Embodiment Construction

[0072] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0073] Embodiments of the present invention provide a vehicle obstacle avoidance method, such as figure 1 As shown, the method may include:

[0074] Step 101. Detect the first longitudinal distance between the vehicle and the obstacle vehicle. The first longitudinal distance is the distance from the midpoint of the rear of the obstacle vehicle to the first straight line when the vehicle is in the obstacle avoidance state. A straight line that is the midpoint of the vehicle's front and is perpendicular to the direction of travel of the vehicle.

[0075] Step 102, when the first longitudinal distance is less than the first preset distance, detect the current distance between the own vehicle and the obstacle vehicle, the current distance...

Abstract

The invention discloses an obstacle avoidance method and device for a vehicle, and belongs to the active safety of vehicles. The method comprises the steps: detecting a first longitudinal distance from the vehicle to an obstacle vehicle; detecting the current distance from the vehicle to the obstacle vehicle when the first longitudinal distance is less than a first preset distance; inquiring the corresponding relation between preset lateral and longitudinal distances and a first enhanced signal value, and determining the first enhanced signal value corresponding to the current distance; Determining first motion control parameters through an enhancement learning method according to the current distance when the first enhanced signal value is greater than a first preset value, wherein the first motion control parameters comprises a reference force value of an accelerator or a brake and a rotation reference angle of a steering wheel; and controlling the vehicle to complete the obstacle avoidance operation according to the first motion control parameters. The method and device solve problems of poorer stability, lower reliability and poorer flexibility in an obstacle avoidance process, improve the stability, reliability and flexibility, and are used for vehicle control.

Description

technical field [0001] The invention relates to the field of automobile active safety, in particular to a vehicle obstacle avoidance method and device. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living standards, automobiles have replaced traditional means of transportation. As there are more and more vehicles on the road, if the vehicle obstacle avoidance is not effectively controlled, traffic safety accidents may occur. As one of the key technologies of automotive active safety systems, vehicle obstacle avoidance methods have received extensive attention. [0003] In the related technology, the vehicle obstacle avoidance method uses the camera and radar to detect the position of the obstacle vehicle, obtains the lateral distance between the vehicle and the vehicle in front, the longitudinal distance between the vehicle and the vehicle in front, and the distance between the vehicle and the ...
