Problems solved by technology

However, this method cannot avoid the risk of sudden congestion of vehicles in the side lane or vehicles driving out of the intersection. It can only avoid rear-end collisions with vehicles in front, but cannot avoid collisions caused by side vehicles.

Embodiment Construction

[0042] In order to enable those skilled in the art to further understand the features and technical contents of the present invention, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and implementation methods.

[0043] like figure 1 Shown is the first flow chart of the automobile adaptive cruise control method in the embodiment of the present invention, including the following steps:

[0044] Step 101: start.

[0045] Step 102: Enter adaptive cruise.

[0046] The embodiment of the present invention is directed to an adaptive cruise system, and the automobile adaptive cruise control method provided by the present invention can be specifically executed by an adaptive controller.

[0047] Step 103: Obtain the current vehicle speed, and obtain the first vehicle distance value according to the vehicle speed.

[0048] Specifically, the vehicle speed can obtain the current vehicle speed in real time through ...

Abstract

The invention relates to the technical field of car cruise control, in particular to a car self-adaptive cruise control method and system. The car self-adaptive cruise control method comprises the steps that self-adaptive cruise entering is conducted; the current car speed is obtained, and the first car distance value is obtained according to the car speed; whether the car distance between a car and a car in front is smaller than the first car distance value or not is detected; if yes, whether the car distance between the car and a left car or between the car and a right car is larger than thefirst set car distance or not is detected; if yes, whether the car distance between the car and a car behind is larger than the first car distance value or not is detected; and if yes, self-adaptivecruise exiting is conducted. Through the car self-adaptive cruise control method and system, occurring of the accident of collision or tailgating is avoided, so that the safety and flexibility of cruise driving are improved.

Description

technical field [0001] The invention relates to the technical field of automobile cruise control, in particular to an automobile adaptive cruise control method and system. Background technique [0002] Adaptive Cruise Control (ACC) is an intelligent cruise control technology that collects vehicle speed signals through wheel speed sensors to control the vehicle speed, and continuously scans the road ahead of the vehicle through the vehicle distance sensor installed at the front of the vehicle In order to lock the vehicle driving directly in front, and then maintain a constant distance between vehicles. When the vehicle in front accelerates, the vehicle automatically accelerates; when the vehicle in front decelerates, the vehicle automatically decelerates; when the vehicle in front brakes suddenly, the vehicle also decelerates rapidly. [0003] However, for the following three situations, adaptive cruise control can only perform emergency braking. If the distance between vehi...
