A vehicle screening method and device based on adaptive cruise control

Abstract

The invention discloses a vehicle screening method and device based on adaptive cruise control. The method includes: acquiring multiple historical position coordinates of vehicles in front; respectively converting the historical position coordinates into the current position of the vehicle Relative position coordinates with a relative relationship; using the relative position coordinates to predict the trajectory of the corresponding vehicle in front; judging whether the trajectory of the vehicle in front is within the driving lane of the vehicle, and if so, the vehicle in front is Filtered as the following target of the vehicle under adaptive cruise control. Through the vehicle screening method provided by the embodiment of the present application, it can replace the driver to perform acceleration and deceleration commands to follow the vehicle, improve the accuracy of the target screening of the ACC system and reduce miscontrol, so as to reduce the sudden acceleration or deceleration of the vehicle to the driver. discomfort caused by staff.

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.
