Embodiment Construction

[0067] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0068] Intelligent driving vehicles are equipped with various sensors such as cameras, millimeter-wave radars, ultrasonic radars, vehicle speed sensors, and navigation and positioning systems. Through the sensory information fusion module, the original information obtained from the sensors can be fused, analyzed, and processed to extract lane lines. , road speed limit, obstacle information, vehicle speed, acceleration, gear and other information. Then through ...

Abstract

The invention provides a vehicle following control system and method for an intelligent driving vehicle. The corresponding vehicle following time interval and the safe parking distance are obtained according to the real-time vehicle speed of the intelligent driving vehicle and the real-time traffic state of the road where the intelligent driving vehicle is located, and then the vehicle following speed and the distance with the front vehicle are automatically adjusted. The real-time traffic state of the road, the real-time vehicle speed of the vehicle, the consistent vehicle following time interval and the safe parking distance are adopted, and compared with the existing fixed time interval control strategy, the behavior of the intelligent driving vehicle is enabled to better accord with the driving habit of human beings. Furthermore, the real-time traffic state of the road where the intelligent driving vehicle is located is calculated through the speed information of the vehicle in front of the intelligent driving vehicle, and compared with a traditional fixed-point traffic state monitoring method, the method is low in cost and good in real-time performance.

Description

technical field [0001] The present invention relates to the field of intelligent driving vehicles, and more specifically, relates to a vehicle following control system and method for intelligent driving vehicles. Background technique [0002] At present, the intelligent driving technology for car-following scenarios mainly includes ACC (Adaptive Cruise Control, adaptive cruise control) and TJA (Traffic Jam Assistant, traffic jam assistance) control. Both of the existing technologies adopt a timed distance control strategy when following the vehicle in front, which makes it difficult for intelligent driving vehicles to achieve human-like driving in car-following scenarios, let alone satisfying a more comfortable driving experience. Therefore, there is an urgent need for a new car-following control method. Contents of the invention [0003] In view of this, the present invention proposes a follow-up control system and method for an intelligent driving vehicle, in order to a...
