Problems solved by technology

In related technologies, ACC is aimed at several typical driving conditions, and the preset distance is a fixed value. However, in scenes with high traffic flow density such as congestion, ACC maintains a preset distance between the control vehicle and the vehicle ahead in the same lane. The distance will make the vehicle accelerate and decelerate frequently, reducing the energy efficiency of the vehicle

Abstract

The embodiment of the invention discloses a self-adaptive cruise control method and device, equipment and a storage medium. The method comprises the steps that the current driving speed and the historical driving speed of a target vehicle and the actual distance between the target vehicle and a front vehicle in the driving direction of the target vehicle are obtained; obtaining a target car following distance according to the first distance, the preset acceleration and the current driving speed; obtaining a first target speed according to the actual distance and the target vehicle following distance; obtaining a second target speed according to the historical driving speed and the current driving speed; according to the preset cruise vehicle speed, the first target speed and the second target speed, the self-adaptive cruise target speed is obtained; and adjusting the driving speed of the target vehicle based on the adaptive cruise target speed. By the adoption of the method, the running speed of the target vehicle is adjusted based on the self-adaptive cruise target speed associated with the historical running speed of the target vehicle, frequent acceleration and deceleration in the running process of the target vehicle are avoided, and therefore energy consumption is effectively reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of intelligent transportation, and more particularly, to a method, apparatus, device, and storage medium for adaptive cruise control. Background technique [0002] With the development of the field of intelligent transportation, autonomous vehicles have gradually entered people's lives. Adaptive Cruise Control (ACC) is a car function that allows the vehicle cruise control system to adjust the speed to adapt to traffic conditions. The basic function of ACC is to control the vehicle to maintain a predetermined distance from the driver with the preceding vehicle in the same lane. In the related art, ACC is aimed at several typical driving conditions, and the preset distance is a fixed value. However, in scenarios with high traffic flow density such as congestion, ACC is used to control the vehicle to maintain a preset value with the vehicle ahead in the same lane. The distance will cause the ...
