Embodiment Construction

[0016] figure 1 A functional block diagram of a vehicle front road information transmission system 1 according to an embodiment of the present invention is shown. The vehicle ahead road information transmission system 1 is installed on a target vehicle to transmit road information ahead of the target vehicle. The system 1 includes a GPS receiver 2 , a current position indication unit 3 , a road map database 4 as a road map data storage unit, a travel estimated road calculation unit 5 , a vehicle ahead road information generation unit 6 , and a control unit 7 .

[0017] The GPS receiver 2 receives GPS radio waves from GPS satellites, extracts parameters from the received GPS radio waves, and outputs the parameters to the current position indicating unit 3 .

[0018] The current position indication unit 3 processes the output parameters, indicates the current position of the vehicle, and outputs the indicated current position to the travel estimated road calculation unit 5 .

Abstract

The present invention provides a transmission system for supplying information on a road ahead in the vehicle. Advance supposition road is computed by executing map match between current position and stored road map as supposed advance road of vehicle. Road information ahead vehicle are generated as information relative to advance direction of vehicle and about advance supposition information. The control unit make the vehicle advance control unit or prewarning unit to control and prewarn the vehicle. Herein, when information on a road ahead comprise a plurality of information items, the control unit whether similarity among a plurality of information items satisfies given qualification, the control unit transmits any one of plurality of information items to the vehicle advance unit or the prewarning unit.

Description

technical field [0001] The invention relates to a transmission system for vehicle front road information. The system calculates the road the vehicle is traveling on, generates the road information ahead of the vehicle related to the calculated traveling road, and then transmits the road information to the vehicle travel control unit or early warning unit. Background technique [0002] Patent Document 1 describes the following: by map matching between the current position and road map data, calculating a traveling estimated road, which is estimated to be a road on which a target vehicle will travel; generating vehicle-ahead road information on the traveling estimated road; The information is transmitted to the vehicle travel control unit or the early warning unit, respectively, so that they can perform vehicle travel control and early warning. Here, the road information ahead of the vehicle includes (i) road shape information, such as road curvature and road gradient, and (i...
