A vehicle adaptive cruise speed control method, device, processor, vehicle and computer readable storage medium

Abstract

The solution relates to a vehicle adaptive cruising speed control method, a device, a processor, a vehicle and a computer-readable storage medium, so as to adjust the vehicle speed in time when a vehicle in front of an adjacent lane cuts into the lane. The method includes: obtaining the number of motion postures of the target vehicle and the lane parameter information of the lane where the target vehicle is located based on V2V communication; judging whether the target vehicle has a movement tendency to cut into the lane according to the motion posture data of the target vehicle; if so, predicting the target vehicle The cut-in time required for the vehicle to cut into the lane; determine whether the vehicle has a safety risk; if so, determine whether the vehicle exists and the target vehicle exists after the target vehicle cuts into the lane under the premise that the vehicle decelerates at the maximum braking deceleration. The risk of vehicle collision; if it does not exist, determine the target speed of the vehicle, and adjust the adaptive speed of the vehicle according to the target speed.

Description

[0001] Technical field [0002] The present invention belongs to the field of vehicle adaptive cruise control, specifically relates to a vehicle adaptive cruise speed control method, apparatus, processor, automobile and computer-readable storage medium. Background [0003] At present, the adaptive cruise speed control has difficulties in judging the intention of the vehicle in the near lane, because the current adaptive cruise control generally uses millimeter wave radar and camera to perceive the movement trend of the surrounding vehicles, and the environment, perception accuracy and the sampling cycle of the sensor will affect the accurate judgment of the lateral movement trend of the vehicle in front of the lane, and when the vehicle near the lane is cut in, the speed control of the car is not timely, and it is easy to suddenly brake to cause poor user experience or even rear-end collision and other safety accidents. Contents of the Invention [0004] The present invention prov...

AI Technical Summary

Problems solved by technology

[0003] At present, the adaptive cruise control has difficulty in judging the intention of vehicles in the adjacent lane, because the current adaptive cruise control generally uses millimeter-wave radar and cameras to perceive the movement trend of surrounding vehicles, and the environment, perception accuracy and sensor sampling period will affect the detection of vehicles in the adjacent lane. Accurate judgment of the lateral movement trend. When the vehicle in the adjacent lane cuts in, the speed control response of the vehicle is not timely, and it is easy to brake suddenly, causing poor user experience or even rear-end collisions and other safety accidents.
