System and method for improving curve performance of adaptive cruise system

Abstract

The invention discloses a system and method for improving the curve performance of an adaptive cruise system, including an information perception unit, an information decision-making unit, and an information execution unit; the information perception unit includes a target detection module, a vehicle information monitoring module, and a steering control monitoring module. The target detection module obtains the motion state information and road information of the vehicle and the vehicle in front; the vehicle information monitoring module obtains the vehicle motion related information of the vehicle, and the steering control monitoring module is used to obtain whether the steering wheel of the vehicle has steering angle information; the information decision-making unit is based on The information obtained by the information sensing unit determines the expected acceleration, expected speed and torque information of the vehicle; the information execution unit includes a vehicle speed control execution module and a steering control execution module, based on the expected acceleration, expected speed and torque information output by the information decision-making unit. Bend longitudinal and corner lateral control. 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 system and method for improving the curve performance of 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 driving. [0003] As an important part of the intelligent driv...

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

In addition, when the driver fails to manipulate the steering wheel for steering control in time due to short-term inattention, the vehicle may deviate from the normal lane and drive to the adjacent lane. In this case, there may be a risk of collision with vehicles in the adjacent lane
