Vehicle self-adaptive cruise speed control method and device, processor, vehicle and computer readable storage medium

Abstract

The invention relates to a vehicle self-adaptive cruise vehicle speed control method and device, a processor, a vehicle and a computer readable storage medium, and aims to adjust the vehicle speed intime when a front vehicle on a close lane is cut into the lane. The method comprises the steps of acquiring the number of moving postures of a target vehicle and lane parameter information of a lane where the target vehicle is located based on V2V communication; according to the moving posture data of the target vehicle, judging whether the target vehicle has a moving trend of cutting into the lane or not; if so, predicting the cut-in time required for the target vehicle to cut in the lane; determining whether the vehicle has a safety risk or not; if so, determining whether the vehicle has therisk of colliding with the target vehicle or not after the target vehicle cuts into the lane on the premise that the vehicle decelerates at the maximum braking deceleration; and if not, determining the target vehicle speed of the vehicle, and adjusting the self-adaptive vehicle speed of the vehicle according to the target vehicle speed.

Description

[0001] Technical field [0002] The invention belongs to the field of vehicle adaptive cruise control, and in particular relates to a vehicle adaptive cruise speed control method, device, processor, automobile and computer-readable storage medium. Background technique [0003] At present, adaptive cruise speed control has difficulty in judging the intention of vehicles in the adjacent lanes, because currently adaptive cruise control generally uses millimeter-wave radar and cameras to sense the movement trend of surrounding vehicles. Accurate judgment of the lateral movement trend, when the vehicle in front of the adjacent lane cuts in, the vehicle speed control response is not timely, and it is easy to suddenly brake, resulting in poor user experience or even rear-end collisions and other safety accidents. SUMMARY OF THE INVENTION [0004] The present invention provides a vehicle adaptive cruise speed control method, device, processor, automobile and computer-readable storag...

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.
