DSRC-based (dedicated short-range communications based) intelligent vehicle map fusion system and method

Abstract

The invention claims a DSRC-based (dedicated short-range communications based) intelligent vehicle map fusion system and method; the system comprises a vehicle positioning module, a local map generating module, a DSRC module, an ADAS (advanced driver assistance systems) map interface, a target vehicle screening module and a map fusion module; the vehicle positioning module is used for acquiring position and attitude of a main vehicle, the local map generating module is used for generating a local map corresponding to the current position of the main vehicle according to data of a vehicular sensor, the DSRC module is used for receiving position, attitude and local map information issued by a target vehicle within a communication range, and transmitting the position, attitude and local mpa of the main vehicle itself, the ADAS map interface module is used for providing protocols and interfaces to access an ADAS map, the target vehicle screening module is used for screening a target vehicle on the same lane as the main vehicle, and the map fusion module is used for fusing the local map of the main vehicle and that of the screened target vehicle to generate an extended local map of the main vehicle. The DSRC-based intelligent vehicle map fusion system and method can provide multi-vehicle sensing capacity sharing to extend the ambient sensing range, helping improve intelligent vehicle assisted driving/automatic driving performance.

Description

technical field [0001] The invention belongs to the field of automation, communication and computer technology, and in particular relates to an intelligent vehicle map fusion system and method based on DSRC (Dedicated Short Range Communications, dedicated short-range wireless communication). Background technique [0002] Environmental perception and map generation are one of the key technologies of intelligent vehicles. In order to improve the performance of intelligent vehicle assisted driving safety warning and automatic driving path planning, intelligent vehicles need to have as large a range of environmental perception as possible. However, traditional methods generally only rely on vehicle The on-board sensor itself makes the vehicle's perception ability extremely limited. [0003] Chinese patent application: vehicle navigation system and vehicle navigation method (application number: CN201010110837.3) discloses a vehicle navigation system and vehicle navigation method,...
