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

Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] Such as Figure 6 As shown, a method for controlling the longitudinal speed of an adaptive cruise system in cornering according to the present invention comprises the following steps:

[0037] When passing through a curve, when judging whether the vehicle in front that the vehicle is tracking remains within the field of vision of the vehicle;

[0038] In response to the vehicle in front tracked by the vehicle has been kept within the field of vision of the vehicle, the vehicle is controlled to follow the vehicle at the cornering speed V=Min (the speed of the vehicle in front tracked, the speed limit value of the curve, and the set cruising speed of the vehicle) The vehicle in front is cornering;

[0039] In response to the vehicle in front tracked by the vehicle is out of the field of view of the vehicle, and no new follow-up target is recognized, the vehicle is co...

Abstract

The invention discloses a cornering longitudinal vehicle speed control method and device of an adaptive cruise system and a computer-readable storage medium. The method includes the steps that in response to the fact that a front vehicle tracked by a current vehicle is always kept in the field of view of the current vehicle, the cornering speed of the current vehicle is controlled to meet the formula V=Min (the speed of the tracked front vehicle, the corner speed limit value, and the set cruising speed of the current vehicle); in response to the fact that the front vehicle tracked by the current vehicle disappears and no new tracking target is recognized, the cornering speed of the current vehicle is controlled to meet the formula V=Min (the instant speed of the current vehicle when the front vehicle disappears, the corner speed limit value, the maximum cornering speed value of the current vehicle, and the set cruising speed of the current vehicle); in response to the fact that the front vehicle tracked by the current vehicle disappears and a new tracking target is recognized, the cornering speed of the current vehicle is controlled to meet the formula V=Min (the instant speed of the current vehicle when the front vehicle disappears, the corner speed limit value, the speed of the newly recognized tracking target, the maximum cornering speed value of the current vehicle, and theset cruising speed of the current vehicle). The method 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...
