Abstract

The invention provides an inquiry system and an inquiry method for highway driving safety information based on a VANET (Vehicular Ad-hoc Network) and relates to the inquiry system and the inquiry method for the highway driving safety information, aiming to effectively obtain information of driving vehicles on a highway in real time. The invention provides an auxiliary driving system which is used for obtaining vehicle information in a certain range based on a vehicular ad-hoc network and providing a direct promotion to a driver through a display screen. The system comprises an information acquisition subsystem, a vehicular ad-hoc network module and a display module. The information acquisition subsystem has the main function of acquiring data related to a current operation state of the vehicle; the vehicular ad-hoc network module is used for establishing a movable ad-hoc network with the vehicles in a certain range, and obtaining the information of the periphery vehicles by carrying out a query. The display module is used for matching the acquired related information of the vehicle and the information of the periphery vehicles obtained by the VANET through an electronic map and directly displaying to the driver. The inquiry system and the inquiry method for the highway driving safety information based on the VANET are applicable to a highway driving process.

Description

technical field [0001] The invention relates to an expressway traffic safety information query system and a query method. Background technique [0002] Our country is in a period of rapid development of expressway construction. The large traffic volume and high driving speed are the salient features of expressways. Therefore, once a major traffic accident occurs, it will bring huge losses to people's lives and property. Knowing the traffic and road environment in time will help the driver to adjust the driving status at any time, adopt corresponding driving strategies, and improve driving safety. Research at the present stage often starts with the relationship between vehicles and people, vehicles and the road environment to inquire about the corresponding information. Such as: through the entry of driver information to obtain the relevant information of the driver, through GPS to obtain the location of the vehicle, according to the connection with the Internet to obtain th...
