Adaptive cruise system cornering longitudinal vehicle speed control method, device and computer readable storage medium

Abstract

The invention discloses a method, device and computer-readable storage medium for controlling the longitudinal vehicle speed in cornering of an adaptive cruise system. Curve speed V=Min (tracked front car speed, curve speed limit value, set cruising speed of the car); in response to the disappearance of the front car tracked by the car and no new follow-up target is recognized, the car is controlled The cornering speed V=Min (the instant speed of the vehicle when the vehicle in front disappears, the curve speed limit value, the maximum cornering speed value of the vehicle, and the set cruising speed of the vehicle); in response to the disappearance and identification of the vehicle in front tracked by the vehicle To the new car following target, control the car's cornering speed V=Min (the car's instant speed when the front car disappears, the speed limit value of the curve, the newly recognized car following target speed value, the car's maximum cornering speed value , the vehicle sets the cruising speed). The invention can improve the safety, comfort and rapidity of the adaptive cruise system in the cornering process.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety systems, and in particular relates to a method, a device and a computer-readable storage medium for controlling the longitudinal speed of a cornering vehicle in an adaptive cruise system. Background technique [0002] With the development of automobile intelligent technology, people pay more and more attention to the comfort and safety of automobile driving, and the resulting intelligent driving technology has increasingly become the main direction of the development of the automobile industry. Intelligent driving technology mainly uses specific technologies (including sensor technology, signal processing technology, communication technology, and computer technology) to identify the environment and state of the vehicle, receive and process information from various sensors, and make analysis and judgments to improve driving comfort. , to reduce the danger of some emergencies during...

AI Technical Summary

Problems solved by technology

Straight car-following on highways and fast roads can play a very good role, but it will greatly reduce comfort and safety for car-following situations on curves

The reason is as follows. During the cruise following a curve, the vehicle in front may lose its target due to turning. At this time, if the vehicle does not recognize a new following target and the cruising speed set by the driver is relatively high, Then there may be rapid acceleration, which is extremely dangerous in some cases
