Embodiment Construction

[0054] The present invention transmits the posture of the self-vehicle to the surrounding vehicles through the vehicle-vehicle information interaction, and according to the posture parameters between the self-vehicle and the front and rear vehicles, warns the driver of danger in the process of changing lanes and eliminates such danger. The method of real-time acquisition of attitude is an existing technology. During implementation, the real-time acquisition of the on-board vehicle information collection equipment can be used to collect the front of the vehicle and the rear of the front vehicle, and the projected distance l (unit m) between the rear of the vehicle and the front of the rear vehicle in the direction of the road. , collect the instantaneous velocity v (unit m / s) and acceleration a (unit m / s) of the vehicle through the vehicle CAN bus 2 ). Through vehicle-to-vehicle information interaction, the information of this vehicle is transmitted to other vehicles. The on-b...

Abstract

The invention provides a vehicle lane change conflict resolution method under a vehicle information interaction condition. The vehicle lane change conflict resolution method comprises the following steps of: judging whether a safe lane change distance is satisfied according to attitude information of a target vehicle and vehicles in front of and behind the target vehicle, and then predicting a safe lane change time range; judging whether a driver has enough time to change lane according to the habits and reaction time of the driver and by taking the safe lane change time range of the target vehicle as a conflict measuring standard, and giving 3 types of prompts to the driver; and if collision danger exists, continuously carrying out braking intervention on the vehicle so as to achieve the aim of eliminating conflict. According to the invention, the possible conflicts can be efficiently and correctly judged in real time through comprehensively analyzing and predicting the state information of a plurality of vehicles; and through giving the direct visual prompt to the driver and performing braking intervention on the vehicle, the life safety and property safety of the driver in the lane change process are ensured.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a vehicle lane-changing conflict resolution method based on vehicle-vehicle information interaction conditions. Background technique [0002] Vehicle lane-changing conflict resolution under the condition of vehicle-vehicle information interaction is an important means to improve the level of active safety assurance in the process of lane changing. The United States, Japan, and the European Union have carried out exploratory research on vehicle-vehicle interactive collaborative control through projects such as IntelliDriveSM, SmartWay, and CVIS, and have achieved a series of research results in the fields of road section collaborative lane changing. Vehicle lane-changing conflict resolution under the condition of vehicle-vehicle information interaction Utilizes vehicle-mounted equipment independent detection information and vehicle-vehicle interaction information, based o...
