Problems solved by technology

At this time, if ACC also controls the vehicle to brake or accelerate during the turning process of the curve, the large longitudinal and lateral acceleration, steering angle, load transfer and other factors may cause the dynamic characteristics of the vehicle to enter the nonlinear region. If the tire When the adhesion between the car and the ground reaches the limit value, the car will have dangerous working conditions such as side slipping on the front and rear axles or even sharp rotation, which will reduce the driving safety of the car on the contrary.

Abstract

The invention is a curve control system for an automobile self-adaptive cruise control system, comprising a data acquisition module for acquiring the signals of each sensor from the CAN bus of the automobile in real time; Whether it is in the state of entering a curve; the road curvature calculation module of the vehicle's driving trajectory, used to calculate the road curvature of the vehicle's driving trajectory; the effective target screening module, used to filter the effective targets ahead; the maximum cornering speed calculation module of the vehicle , which is used to calculate the maximum cornering speed that the vehicle can reach through the curve under the turning radius of the vehicle; the vehicle speed control module is used to make reasonable control of the vehicle according to the driving conditions of the vehicle, and improve the adaptive cruise control system. Environmental awareness in cornering conditions.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a curve control system and method for an automobile adaptive cruise control system. Background technique [0002] In recent years, with the vigorous development of the automobile industry, automobiles have provided great convenience for social transportation. With the rapid growth of car ownership, the traffic flow is gradually increasing, and the resulting traffic accidents, road congestion and environmental pollution are becoming more and more serious. Therefore, improving automobile safety performance and reducing road traffic accidents have become a social issue that people pay attention to, and it is also a major issue that Intelligent Transportation System (ITS) should strive to solve. As an important part of the human-vehicle-road traffic system, the driver has become a weak link of the system due to the limitation of his own conditions. According to the stati...
