BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device mounted on a moving body such as a vehicle, and a management organization device installed in a management center for managing the moving body, and more particularly to driving for driving the moving body. The present invention relates to a terminal device for grasping a driving tendency of a person and a management organization device.

2. Description of the Related Art Conventionally, various devices have been developed for supporting safe driving of vehicles. For example, there is a method of monitoring a steering wheel operation or a braking operation of a driver, detecting a sudden steering wheel or a sudden braking, and calling attention to a driver who frequently performs such an operation (Japanese Patent Laid-Open No. 2000-1).
No. 85676).

When an operation such as a sudden steering wheel or a sudden braking is performed, it may directly cause an accident, or a situation where a sudden steering wheel or a sudden braking has to be performed (for example, too high speed). ) Is sometimes the cause of an accident.

Therefore, it seems very meaningful to monitor steering wheel operation and brake operation, detect sudden steering wheel and sudden braking, and pay attention to the driver who frequently performs these operations.

[0005]

As described above, it is very meaningful to detect a sudden steering wheel or a sudden braking and give caution to a driver who often performs these operations, but it is natural. However, sudden steering and braking are not the only causes of an accident.

For example, an intersection and its vicinity are places where there are many accidents. As a cause of the accident there, when trying to enter an intersection, the speed of the vehicle is suddenly increased or the signal state of the traffic signal is not obeyed. And so on.

Therefore, as a caution for a driver who often operates a sudden steering wheel or a sudden braking, when he or she tries to enter an intersection, the speed of the vehicle is not suddenly increased or the signal state of the traffic signal is not obeyed. It is better to pay attention to the driver as well.

[0008] However, there has been no technique for detecting that the speed of the vehicle is suddenly increased or the vehicle does not follow the signal condition of the traffic signal when entering an intersection.

The present invention has been made in view of the above problems, and a terminal device capable of detecting a sudden increase in the speed of a vehicle at or near an intersection or not following a signal from a traffic signal, and It is intended to provide a management device.

Means for Solving the Problems and Effects Thereof In order to achieve the above object, a terminal device (1) according to the present invention is a terminal device mounted on a mobile body, wherein the position information of the mobile body and the intersection information Based on the map information where the position is shown,
Based on the calculation result of the first positional relationship calculating means for obtaining the positional relationship between the moving body and the intersection, and the speed information of the moving body, the traveling of the moving body in the intersection and in the vicinity of the intersection. It is characterized in that it is provided with a first analysis means for analyzing the state.

According to the terminal device (1), the calculation result (that is, the positional relationship between the moving body and the intersection) by the first positional relationship calculating means (for example, the navigation function) and the moving body Since the mobile body is provided with the first analyzing means for analyzing the traveling state of the moving body in the intersection and in the vicinity of the intersection based on the speed information, the moving body is in the intersection or in the vicinity of the intersection. It is possible to determine whether or not the speed is suddenly increasing. Therefore,
Since it becomes possible to give appropriate advice to the driver who drives the moving body based on the analysis result by the first analyzing means, it is possible to reduce accidents at intersections and It is possible to improve morals.

The terminal device (2) according to the present invention is a terminal device mounted on a moving body, which corresponds to a signal state of a traffic signal to be followed by a driver of the moving body and the moving body and the traffic signal. Based on the positional relationship with the stop position and the speed information of the moving body, when the signal state of the traffic signal is in a predetermined state, traveling of the moving body near the stop position corresponding to the traffic signal It is characterized in that it is provided with a second analysis means for analyzing the state.

According to the terminal device (2), the state of the signal of the traffic light (that is, the traffic light in front of the mobile body) to be followed by the driver of the mobile body and the stop state corresponding to the mobile body and the traffic light. Based on the positional relationship with the position (for example, the position immediately before the traffic light where the signal of the traffic light is visible) and the speed information of the moving body, the signal state of the traffic light is in a predetermined state (for example, red). Is in the state of being lit or in the state of being lit in yellow), since the second analysis means for analyzing the running state in the vicinity of the stop position is provided, the driver of the moving body is provided. It is possible to determine whether the vehicle is traveling according to the state of the signal of the traffic light.

For example, if the speed of the moving body is not slowing down even though the moving body is approaching the traffic light that is lit in red, it is determined that the driver is not following the signal from the traffic light. If the speed of the moving body is increasing in spite of the moving body approaching the traffic light that is lit yellow, the driver can give a signal of the traffic light. Can be determined not to comply. Therefore, it becomes possible to give appropriate advice to the driver who drives the moving body based on the analysis result by the second analysis means, so that accidents at intersections can be reduced and driving can be performed.

Further, since the state of the signal of the traffic light and the positional relationship are obtained based on the image acquired by the image acquisition means (for example, CCD camera) for acquiring the image in front of the moving body, The signal state of the traffic light and the distance to the traffic light can be accurately obtained.

For example, by using a filter that does not pass colors other than red, it is determined whether or not the traffic light to be followed by the driver of the moving body is lit in red based on the position of a point shining above a predetermined brightness. In addition, it is possible to determine whether or not the moving body is approaching the traffic light based on the movement of the bright point.

It can be caught accurately. Therefore, it is possible to more accurately determine whether or not the speed of the moving body is rapidly increasing at or near the intersection, or, for example, the moving body is lit in red. When the moving body is approaching a traffic signal, it is determined whether the speed of the moving body is slowing down, or when the moving body is approaching a traffic light that is lit yellow, The determination as to whether or not the speed is increasing can be made even more accurately.
