The present invention solves the above problems by the following means.
The invention of claim 1 includes a positioning unit that acquires navigation information including vehicle position information , speed information, and angular velocity information , and each vehicle-mounted device that is mounted for each vehicle having an output unit that displays and outputs information. A vehicle information transmission system comprising a server for managing information from each in-vehicle device via a communication network, wherein each in-vehicle device detects vehicle navigation information through the positioning unit, and A communication unit that transmits and receives information including the navigation information to and from a server, and an output unit that outputs information from the server received by the communication unit to the output unit. flat rate information of said the server communication means for transmitting and receiving information including the navigation information with each vehicle device, for each road section, the navigation information which the previously received through the server communication means A storage means for storing a specified speed of the normal running is a value, detected for each vehicle, the navigation information for all vehicles located in front of the predetermined road section by the vehicle as a reference via the server communication means Forward information detecting means, average speed calculating means for calculating an average speed for each road section from the navigation information detected by the forward information detecting means, and an average speed calculated by the average speed calculating means, A determination unit that determines whether the road speed is lower than a specified speed during normal driving for each road section, and when the determination unit determines that the average speed is lower than the specified speed, generates warning information that prompts a traffic jam, to the in-vehicle device of the vehicle as a reference in the front information detecting means, and warning means for transmitting the warning information through the server communication means, for each of the road section, the Uphill judgment means for judging whether or not the road section is an uphill based on the navigation information received through the communication means, and the storage means for each of the road sections during the normal driving Is stored in association with the determination result by the uphill determination means, and the warning means, when the determination means determines that the average speed is below the specified speed in the road section, When the road section is determined to be an uphill by the uphill determination means, warning information that prompts a traffic jam based on the uphill information is generated .
さらに、記憶手段により、サーバにおいて取得した所定の道路区間を走行する車両の航法情報、特に速度情報を予め記憶することができるので、一定期間記憶した速度情報から、その平均値を算出することで、当該道路区間が渋滞か否かを判定する上で規準となる規定速度を適切に設定することが可能となる。これにより、高精度の渋滞判定を実現することができる。
Further , since the navigation means of the vehicle traveling on the predetermined road section acquired in the server, particularly the speed information, can be stored in advance by the storage means, the average value can be calculated from the speed information stored for a certain period. Therefore, it is possible to appropriately set a prescribed speed as a standard for judging whether or not the road section is congested. Thereby, highly accurate traffic jam determination can be realized.
さらに、渋滞が生じている道路が上り坂であるかを判定することができるので、渋滞情報に加え、この上り坂の情報もユーザに対して報知することが可能となる。これにより、上り坂において無意識のうちに減速してしまう渋滞の要因となる事態を防ぐことができ、渋滞発生の抑制に貢献する。 Furthermore , since it is possible to determine whether the road in which the traffic jam occurs is an uphill, this uphill information can be notified to the user in addition to the traffic jam information. As a result, it is possible to prevent a situation that causes a traffic jam that unintentionally decelerates on an uphill, contributing to the suppression of the occurrence of the traffic jam.
