Embodiment

[0100] figure 2 Shown is a one-way three-lane (two-way six-lane) highway, which is based on the application scenario of the rear-end collision avoidance control method for autonomous vehicles. We assume an application scenario as shown in Table 2 below:

[0101] Table 2

[0102] vehicle position (x) speed (v) Acceleration (a) Vehicle length (L) ACC vehicle 23m 26m / s -0.5m / s 2

5m Current leader 56m 26m / s -0.5m / s 2

5m Current follower 0m 28m / s 1m / s 2

5m Left follower -4m 30m / s 0m / s 2

5m Left leader - - - - Right follower -2m 24m / s 0.5m / s 2

5m right leader - - - -

[0103] The first step is to calculate δ according to the current situation * value of: Take the positive value, which is Then calculate the collision probability If P>20%, the rear-end anti-collision control system is turned on, and now it is assumed that the collision probability is greater than...

Abstract

The invention discloses a rear-end collision avoidance control method, system, computer, and storage medium of an automatic driving vehicle, wherein the control method includes: S1: Collecting the data of the automatic driving vehicle and the adjacent rear vehicles on the current lane of the automatic driving vehicle Vehicle information, and calculate the critical reaction time based on the vehicle information; S2: Calculate the current collision probability between the rear vehicle and the self-driving vehicle based on the critical reaction time, and if the collision probability is higher than a preset threshold, control The self-driving vehicle is in the rear-end collision avoidance control mode, otherwise, the self-driving vehicle is controlled to be in the original control mode of automatic driving. The present invention effectively reduces the risk of rear-end collisions caused by driver distraction and operational errors in the mixed flow of manual driving and automatic driving in the transitional stage of automatic driving development through the above-mentioned control method, and effectively improves the high-speed driving speed in the transitional stage of automatic driving development. Road traffic safety.

Description

technical field [0001] The invention belongs to the field of intelligent driving, and in particular relates to a rear-end anti-collision control method, system, computer and storage medium of an automatic driving vehicle. Background technique [0002] In recent years, with the rapid development of my country's economy and the improvement of people's living standards, the number of motor vehicles is also increasing. According to relevant data from the Ministry of Public Security, as of the end of 2019, the number of motor vehicles in my country reached 348 million, and it still maintains a rapid growth trend. The rapid increase in the number of motor vehicles has brought about serious safety problems. Self-driving vehicles have the potential to alleviate traffic safety problems, so they are regarded as an important guide for future driving development. However, due to the gradual nature of its development process, it will inevitably face a stage where human-driven vehicles ...
