Embodiment 1

[0103] see figure 1 , figure 1It is a schematic flowchart of a control method for preventing rear-end collision of a vehicle disclosed in an embodiment of the present invention. Such as figure 1 As shown, the method may include the following steps.

[0104] 101. When it is detected that there is a following vehicle behind the target vehicle, the vehicle control system judges whether there is a collision risk between the following vehicle and the target vehicle; if yes, execute step 102; if not, end this process.

[0105] In the embodiment of the present invention, before step 101 is performed, the vehicle control system may detect whether there is a subsequent vehicle behind the target vehicle through an environment detection device provided on the target vehicle. Wherein, the environmental detection device may include sensors and / or camera modules, and the sensors may include but not limited to one of the following types of sensors: millimeter wave radar sensors, ultrasoni...

Embodiment 2

[0127] see figure 2 , figure 2 It is a schematic flowchart of another vehicle rear-end collision prevention control method disclosed in the embodiment of the present invention. Such as figure 2 As shown, the method may include the following steps.

[0128] 201. When detecting that there is a following vehicle behind the target vehicle, the vehicle control system acquires first motion information and second motion information.

[0129] Wherein, the first motion information includes at least the current driving speed and acceleration of the target vehicle; the second motion information includes at least the current driving speed, acceleration and lateral speed of the subsequent vehicle.

[0130] In the embodiment of the present invention, the vehicle control system can obtain the first motion information and the second motion information through the environment detection device installed on the target vehicle, wherein the environment detection device can include a sensor a...

Embodiment 3

[0197] see image 3 , image 3 It is a structural schematic diagram of a vehicle control system disclosed in an embodiment of the present invention. Such as image 3 As shown, the vehicle control system may include:

[0198] The first judging unit 301 is configured to judge whether there is a collision risk between the following vehicle and the target vehicle when it is detected that there is a following vehicle behind the target vehicle.

[0199]In the embodiment of the present invention, before the first judging unit 301 judges whether there is a risk of collision between the following vehicle and the target vehicle, the first judging unit 301 can detect whether there is a following vehicle behind the target vehicle through an environment detection device installed on the target vehicle. Wherein, the environmental detection device may include sensors and / or camera modules, and the sensors may include but not limited to one of the following types of sensors: millimeter wav...

Abstract

The embodiment of the invention relates to the technical field of vehicles and discloses a vehicle rear-end collision prevention control method and a vehicle control system. The method comprises the following steps of: when detecting that a subsequent vehicle exists behind a target vehicle, the vehicle control system judges whether a collision risk exists between the subsequent vehicle and the target vehicle or not; if yes, the vehicle control system judges whether the adjacent area of the target vehicle has a drivable condition or not, and if yes, the vehicle control system plans the expectedtraveling track of the target vehicle and controls the target vehicle to travel according to the expected traveling track so that the target vehicle can avoid the following vehicle. By implementing the embodiment of the invention, rear-end collision accidents can be avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a control method and a vehicle control system for vehicle rear-end collision prevention. Background technique [0002] With the development of modern transportation and the rapid development of the automobile industry, people's travel has been improved, but traffic accidents have become more frequent, especially rear-end collisions. In order to reduce the occurrence of rear-end collision accidents, at present, most vehicles are equipped with a collision warning device, which can provide a collision warning to the driver. However, it has been found in practice that even if the driver is given a collision warning, a rear-end collision will occur due to the driver's untimely response. It can be seen that how to effectively avoid the occurrence of a rear-end collision is one of the hot issues to be solved urgently. Contents of the invention [0003] The embodiment of the inventio...
