Embodiment Construction

[0054] 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.

[0055] The embodiment of the present invention provides an automatic car following method, such as figure 1 As shown, the method includes:

[0056] Step 101. Obtain n enhanced signal values, which are used to indicate the reliability of the own vehicle from the preceding vehicle. The n enhanced signal values ​​are obtained by dividing the vehicle-following distance into n segments at equal intervals, and determining the enhanced signal value for a sub-region corresponding to each segment distance. The following distance is the preset distance that the vehicle follows the preceding vehicle, and the area corresponding to the following distance is a reliable area, which is composed of n sub-areas, where n is an integer greater than 2.

Abstract

The invention discloses a method and device for automatically following a car, belonging to the field of active safety of automobiles. The method includes: obtaining n enhanced signal values, the n enhanced signal values ​​are obtained by dividing the vehicle following distance into n sections at equal intervals, and determining the enhanced signal value for each sub-area corresponding to the distance, and the following vehicle distance is preset The driving distance of the vehicle following the vehicle in front, the area corresponding to the following distance is the reliable area, and n is an integer greater than 2; n normalized values ​​are obtained, and n normalized values ​​are normalized to n enhanced signal values According to the n enhanced signal values, n normalized values ​​and the current driving position of the vehicle, it is judged whether the vehicle is in the reliable area; when the vehicle is in the reliable area, the machine learning method is used to control the vehicle The car completes the automatic follow-up action. The invention solves the problem of low reliability of automatic car following, realizes the effect of improving the reliability of automatic car following, and is used for automatic car following.

Description

technical field [0001] The invention relates to the field of automobile active safety, in particular to an automatic car following 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 quickly entered ordinary families. Traffic congestion is becoming more and more serious due to the increasing number of vehicles on the road. In the case of long-term congestion, the vehicle is driving very slowly, and the vehicle is constantly switching between the two states of stop and go. At this time, the driver needs to pay great attention to the distance between the vehicle and the vehicle in front, otherwise it will Cause traffic accidents such as rear-end collision, in this way, it is easy to make the driver be in a fatigue driving state, and traffic accidents are prone to occur. As one of the key technologies of automotive safety assistance systems, automat...
