Vehicle screening method and device based on self-adaptive cruise control

Abstract

The invention discloses a vehicle screening method and device based on self-adaptive cruise control. The method comprises the following steps that: multiple historical position coordinates of a frontvehicle are acquired; the historical position coordinates are converted into relative position coordinates having relative relationships with the position of a vehicle at the current moment; the driving track of the corresponding front vehicle is predicted by utilizing the relative position coordinates; and whether the driving track of the front vehicle is in the driving lane of the vehicle or notis judged, and if so, the front vehicle is screened as a following target of the vehicle under the self-adaptive cruise control. With the vehicle screening method provided by the embodiment of the invention, a driver can be replaced to execute acceleration and deceleration commands to carry out vehicle following driving, the target screening accuracy of an ACC system is improved, and error control is reduced, and therefore, discomfort brought to the driver by sudden acceleration or deceleration of the vehicle is reduced.

Description

technical field [0001] The present invention relates to the technical field of adaptive cruise control, in particular to a vehicle screening method and device based on adaptive cruise control. Background technique [0002] With the vigorous development of the automobile industry, intelligent driving has gradually entered people's lives. As an important part of assisted intelligent driving, adaptive cruise control (Adaptive Cruise Control, ACC) technology has received extensive attention. So far, the ACC system has been fully proved to have the function of reducing driver fatigue and improving vehicle driving safety, and has been widely used. [0003] However, the ACC system has poor adaptability to the environment. For example, when the vehicle in front left suddenly jams into the lane in which the vehicle is driving, the ACC system will change the following target from the vehicle directly in front to the vehicle in front left, and then cause the vehicle to suddenly deceler...

Problems solved by technology

[0003] However, the ACC system has poor adaptability to the environment. For example, when the vehicle in front left suddenly jams into the lane in which the vehicle is driving, the ACC system will change the following target from the vehicle directly in front to the vehicle in front left, and then cause the vehicle to suddenly decelerate; Or when the vehicle in front left suddenly does not want to block the lane in which the vehicle is driving, the ACC system will change the following target from the vehicle in front left to the vehicle directly in front, and then cause the vehicle to accelerate suddenly, sudden acceleration and deceleration will cause the driver to feel uncomfortable , even highly tense

For another example, when the vehicle in front of you is following a sudden turn, it will cause the ACC system to lose the following target, and then accelerate suddenly, which will also cause the driver to feel uncomfortable.
