Problems solved by technology

The safety distance model is widely used in computer simulation, because in the research process, the calibration model can be calibrated with the general perceptual assumptions of driving behavior, but the model is only well used in simulation software, and it is complex in practice. It is difficult to match the maximum traffic volume and does not consider the psychological state of the driver

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] The present invention is based on the vehicle-vehicle coordination car-following auxiliary control system. The system is mainly based on vehicle-to-vehicle communication. Through the wireless communication device set up on the vehicle, the motion state parameters of the own vehicle are sent to the surroundings. Motion state parameters, to determine the target object that needs to take the car-following behavior. If car-following behavior is required, the system will enter the car-following mode and control the vehicle so that it can follow the vehicle in front within a certain safe car-following distance and safety car-following margin to prevent rear-end collision accidents.

[0031] Such as figure 1 The two-way four-lane road section shown is a typical application scenario of the car-following assistance control system based on vehi...

Abstract

The invention discloses a following auxiliary control system based on inter-vehicle cooperation. The system is mainly composed of an inter-vehicle wireless local area network communication core system and a following auxiliary control core system. As for the inter-vehicle wireless local area network communication core system, motion state information of each vehicle is sent to the periphery in a packed mode mainly by means of wireless local area networks installed on various vehicles, and therefore surrounding vehicles can receive the motion state information of each vehicle. The following auxiliary control core system is composed of two control modules, one control module is used for searching vehicles needing to be followed for a rear vehicle, and the other control module is a following control module. By means of cooperative control of the two control modules, the system can complete searching of a target object needing to be followed and complete acceleration and deceleration actions needing to be adopted for auxiliary following actions, the purpose of safe following is achieved, and rear-end collision accidents are prevented.

Description

technical field [0001] The invention relates to a car-following auxiliary control system based on vehicle-vehicle coordination. The system is mainly based on vehicle-to-vehicle communication, by obtaining the motion state parameters of the own vehicle and the motion state parameters of the surrounding vehicles to determine the target object that needs to take the car-following behavior. If car-following behavior is required, the system will enter the car-following mode and control the vehicle so that it can follow the vehicle in front within a certain safe car-following distance and safety car-following margin. Background technique [0002] According to the statistics of the Traffic Management Bureau of the Ministry of Public Security, in 2010, 3,906,164 road traffic accidents were reported nationwide, a year-on-year increase of 35.9%. Among them, there were 219,521 road traffic accidents involving casualties, resulting in 65,225 deaths, 254,075 injuries, and direct propert...
