Abstract

An information presentation system includes a road identification portion specifying a road that a vehicle goes through, a road usage information storage portion storing road usage information, which associates with and indicates usage status of a road, a traffic hazard information storage portion storing traffic hazard information, which indicates a caution point in road travelling, an information presentation portion presenting the traffic hazard information of the road specified by the road identification portion, and a presentation suppression portion suppressing presentation of the traffic hazard information of the road, which is specified by the road identification portion, when the usage status of the road indicated by the road usage information satisfies a presentation suppression condition.

What is claimed is: 
     
         1 . An information presentation system comprising:
 a road identification portion specifying a road that a subject vehicle is going through;   a road usage information storage portion storing road usage information, which associates with and indicates usage status of a road;   a traffic hazard information storage portion storing traffic hazard information, which indicates a caution point in road travelling;   an information presentation portion presenting the traffic hazard information of the road specified by the road identification portion; and   a presentation suppression portion suppressing presentation of the traffic hazard information of the road, which is specified by the road identification portion, when the usage status of the road indicated by the road usage information satisfies a presentation suppression condition.   
     
     
         2 . The information presentation system according to  claim 1 , wherein
 the presentation suppression portion determines that the presentation suppression condition is satisfied and suppresses the presentation of the traffic hazard information as a usage frequency of the road by the subject vehicle is increased.   
     
     
         3 . The information presentation system according to  claim 1 , wherein
 the presentation suppression portion presents the traffic hazard information when the traffic hazard information has not been presented predetermined times.   
     
     
         4 . The information presentation system according to  claim 1 , wherein
 the presentation suppression portion presents the traffic hazard information on a specified day.   
     
     
         5 . The information presentation system according to  claim 1  further comprising
 a driver status estimation portion estimating a driver status, wherein 
 the presentation suppression portion presents the traffic hazard information when the driver status estimation portion determines that the driver status is in a wrong condition. 
 
     
     
         6 . The information presentation system according to  claim 1  further comprising
 a driving environment estimation portion estimating a driving environment at a position of the subject vehicle, wherein 
 the presentation suppression portion presents the traffic hazard information when the driving environment estimation portion determines that the driving environment is in a wrong condition. 
 
     
     
         7 . The information presentation system according to  claim 1 , wherein
 a travelling frequency indicating the usage status of the road is reduced when a driver does not use sequentially for a predetermined period.   
     
     
         8 . The information presentation system according to  claim 1  further comprising
 a driver identification portion identifying a driver, wherein 
 the presentation suppression portion suppresses the presentation of the traffic hazard information with respect to the road specified by the road identification portion when the usage status of the road by the driver specified by the driver identification portion satisfies the presentation suppression condition. 
 
     
     
         9 . A presentation apparatus used in an information presentation system, wherein
 the information presentation system including:
 a road identification portion specifying a road that a vehicle goes through; 
 a road usage information storage portion storing road usage information, which associates with and indicates usage status of a road; 
 a traffic hazard information storage portion storing traffic hazard information, which indicates a caution point in road travelling; 
 an information presentation portion presenting the traffic hazard information of the road specified by the road identification portion; and 
 a presentation suppression portion suppressing presentation of the traffic hazard information of the road, which is specified by the road identification portion, when the usage status of the road indicated by the road usage information satisfies a presentation suppression condition, and 
   the presentation apparatus includes at least the information presentation portion.   
     
     
         10 . The information presentation system according to  claim 3 , further comprising:
 a driver status estimation portion estimating a driver status;   a driving environment estimation portion estimating a driving environment at a position of the vehicle; and   a driver identification portion identifying a driver, wherein   the presentation suppression portion presents the traffic hazard information when the driver status estimation portion determines that the driver status is in a wrong condition,   the presentation suppression portion presents the traffic hazard information when the driving environment estimation portion determines that the driving environment is in a wrong condition, and   the presentation suppression portion suppresses the presentation of the traffic hazard information with respect to the road specified by the road identification portion executed by the information presentation portion when the usage status of the road by the driver specified by the driver identification portion satisfies the presentation suppression condition.
