Embodiment Construction

[0033] The following are specific embodiments of the present invention, and further describe the technical solution of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0034] Such as Figure 1-2 As shown, the adaptive cruise system based on vehicle-vehicle communication includes a vehicle-mounted controller 1, a satellite positioning system 6 for providing satellite positioning vehicle position information, and a wireless communication module 2 for realizing vehicle-vehicle communication. The satellite positioning system 6 and wireless The communication module 2 is connected to the on-board controller 1 respectively. The on-board controller 1 can be an on-board APP application, a part of the Internet of Vehicles, or a separate ECU which stores the vehicle identification code and other data related to vehicle attributes. The on-vehicle controller 1 receives information on the speed of the vehic...

Abstract

The invention provides a self-adaptive cruise system and a control method based on vehicle to vehicle communication, pertaining to the technical field of cars with the purpose of improving cruise accuracy. The system comprises a vehicle-mounted controller, a satellite positioning system and a wireless communication module. The satellite positioning system and the wireless communication module are connected with the vehicle-mounted controller. The vehicle-mounted controller is used for calculating the time that a car takes to overtake a front car based on information of the front car and the car. When the calculated time is less than the pre-set threshold value and the distance between two cars is larger than or equal to the safety distance threshold value, the car decelerates and determines to cruise at the constant speed based on the speed of the front car. The method comprises following steps of: A, establishing a communication network; B, determining whether a signal is emitted by a front car or not; C, cruising at the constant speed when no signal is emitted by the front car; D, calculating the time that the car takes to overtake the front one based on information of the front car. When the calculated time is less than the pre-set threshold value, the car decelerates and sends a early warning signal to the front car. The system and the method help raise cruise accuracy and self-adaptation.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an adaptive cruise system and a control method based on vehicle-vehicle communication. Background technique [0002] The comfort of driving a car has been paid more and more attention by consumers. The adaptive cruise system can not only make the car run at a set speed when there is no car in front, but also make the car automatically accelerate and decelerate to maintain the speed when there is a car in front. Drive at a safe distance from the vehicle in front, thereby reducing the driver's heavy driving tasks, and to a certain extent, reducing the fatigue of the driver driving on high speed for a long time, thereby reducing the incidence of traffic accidents. Therefore, the adaptive cruise system is a The extremely important driving assistance system will be vigorously promoted and applied. [0003] At present, major automobile OEMs at home and abroad have developed adaptive...
