The distance to the warning point is set in the safety operation system, and this distance can be changed automatically or as required by the driver in the safety operation system. Here, it is assumed that the distance to the warning point is set to 700m.

As shown in FIG. 4, there is a tunnel in front of the vehicle 70. After the vehicle (70) continues and reaches 700m in front of the tunnel (75), it is the 'tunnel, tunnel area' in this safe operation system. Please take off your sunglasses. ' After that, the selected warning chime such as 'beep-beep' lasts for about 3 seconds as an example.

The distance to the warning point in front of the danger zone may be determined automatically by this safe operating system, and may be set by the operator in particular. And the distance of this warning point is automatically converted according to the driving speed. For example, in the tunnel area, warning messages and warning chimes will be heard at a point farther than 700m at high speeds, and at shorter distances at low speeds.

In addition to tunnels, warning messages and warning chimes will be sounded for each danger zone when a designated warning point in front of the relevant danger zone, such as a foggy area, an accident-prone area, a sharp curve area, etc., is reached. It is possible to do

The data stored in the storage data unit 603 of the safety operation system includes information on a warning point, a danger zone start point, a danger zone end point, and the like, so that necessary data can be selectively used.

It rings. And if the driver changes this basic setting, the changed warning point is calculated using the location data for the basic warning point, and the warning message and the warning chime are generated based on the changed warning point.

Information about warning points, hazardous area start points, and hazardous area end points can also be used to identify each point. In other words, if the warning points calculated by considering the speed of the vehicle from the starting point of the danger zone and the slope of the road do not coincide with each other, the warning message and the warning chime will be sounded only if they match again after performing the calculation to check for them. do.

In addition, the stored data includes information on the location of the road, so that it is possible to check whether the vehicle is running on the road while driving. For example, if the maximum speed limit of a running highway is 100 km / h, a warning message and a warning chime will sound when the vehicle speed reaches 80 km, indicating that it is approaching the maximum speed limit. In addition, if the headlights are not turned on when running in a foggy area, a warning message and a warning chime will sound.

As described above, the safety operation system uses a plurality of channels and about 10 to about 9 to 12 channels to determine the position of each of them. This is different from the way satellites are used. Since the use of such a plurality of channels, as described above, the GPS engine unit 602 for processing a plurality of position information is included in the configuration of the present safety operation system, each GPS satellites 71S, 72S, 73S Processing location information from.
