Description

請求項１の発明は、高速道路に付随して設置されているサービスエリアまたはパーキングエリア内の車両の位置を自車位置として検出する自車位置検出手段と、サービスエリアまたはパーキングエリアへ進入するための導入路と高速道路との分岐点を基準に逆走判定範囲を設定する範囲設定手段と、逆走判定範囲内における車両の走行距離を取得する走行距離取得手段と、走行距離の合計が所定の閾値より大きい場合に車両が逆走しようとしていると判断する逆走判定手段と、逆走判定手段によって車両が逆走しようとしていると判定されたとき所定の報知を行う報知手段とを備える車載装置である。 According to the first aspect of the present invention , the vehicle position detecting means for detecting the position of the vehicle in the service area or the parking area installed along with the expressway as the vehicle position, and for entering the service area or the parking area . A range setting means for setting a reverse running determination range based on a branch point between the introduction road and the expressway, a travel distance obtaining means for obtaining a travel distance of the vehicle within the reverse running determination range, and a total of the travel distance is predetermined On-vehicle equipped with reverse running determination means for determining that the vehicle is going to run backward when the threshold is greater than the threshold, and notification means for performing predetermined notification when the reverse running judgment means determines that the vehicle is going to run backward Device.

Claims

Vehicle position detection means for detecting the position of the vehicle in the service area or parking area attached to the expressway as the vehicle position ;
Range setting means for setting a reverse run determination range based on a branch point between the introduction road for entering the service area or the parking area and the expressway;
Mileage acquisition means for acquiring the mileage of the vehicle within the reverse running determination range;
Reverse running determination means for determining that the vehicle is going to run backward when the total of the travel distance is greater than a predetermined threshold;
An in-vehicle device comprising: a notification unit that performs a predetermined notification when the reverse determination unit determines that the vehicle is going to reverse.

The in- vehicle device according to claim 1,
The range setting means is a fan-shaped range centered on the branch point, a predetermined first distance as a radius, and a predetermined first angle as a central angle, wherein the central angle is the above-mentioned at the branch point. A vehicle-mounted device that spreads from a traveling direction of an expressway toward the introduction road.

The in-vehicle device according to claim 2,
The in-vehicle device according to claim 1, wherein the first angle is calculated based on an inferior angle between a traveling direction of the highway and a traveling direction of the introduction path at the branch point.

The in- vehicle device according to claim 1,
The range setting means is a fan-shaped range centering on the branch point, having a predetermined second distance as a radius, and having a predetermined second angle as a central angle, and the central angle at the branch point vehicle device, characterized in that shall spread to the right and left around the traveling direction of the introduction path.

The in-vehicle device according to claim 4,
The in-vehicle device, wherein the second angle is calculated based on a subordinate angle between a traveling direction of the highway and a traveling direction of the introduction path at the branch point.

In the in- vehicle device according to any one of claims 2 to 5,
The on-vehicle apparatus characterized in that the first distance or the second distance is set to a value larger than the length of the introduction path.

In the in- vehicle device according to any one of claims 2 to 6,
The in-vehicle apparatus, wherein the reverse running determination unit sets the threshold based on a value obtained by subtracting a length of the introduction path from the first distance or the second distance .
