DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a schematic block diagram of a moving object detection alarm device 1 according to the present embodiment. Each driver carries an IC card 2 which also serves as his / her own driver's license.
An IC card reader 11 is installed in a vehicle on which is mounted.

In the IC card 2, driving skill information is written together with the personal identification code of the driver who carries the IC card.
The driving skill information includes driving level information based on the driving history, as well as information such as the driving skill of the driver in a situation where an alarm may be required, such as the required time for a right turn, the required time for a left turn, and the median value of the braking time. included.

The driving skill information read by setting the IC card 2 in the IC card reader 11 is input to the alarm control means 10. The vehicle also has running state detecting means 12 for detecting a running state such as a time required for a right turn or a braking time, and the running state information detected by the running state detecting means 12 is used as a driving skill determining means. Entered into 13,
The driving skill discriminating means 13 includes an IC card reader 11
The driving skill information of the card 2 is input.

The driving skill discriminating means 13 accumulates and analyzes the driving state information for a predetermined time to discriminate the driving skill rank, and
When it is determined that the driving skill rank is improved as compared with the driving skill information of the card 2, an instruction is given to the updating device 14 to update the driving skill information of the IC card 2 by the updating device 14.

Further, the moving body detection alarm device 1 is provided with a vehicle performance memory 21 for storing vehicle performance such as braking, acceleration, and cornering performance of the vehicle as data. It is input to the alarm control means 10. On the other hand, it has a surrounding environment detecting means 22 for detecting surrounding environment such as weather such as sunny, rain, snow, etc., day / night, road surface friction coefficient, etc., and the surrounding environment information is inputted to the vehicle performance correction determining means 23. Is done.

When the vehicle performance correction determining means 23 determines that it is better to correct the vehicle performance information in the vehicle performance memory 21 from the surrounding environment information, the vehicle performance correction determining means 23 instructs the correcting means 24 to correct the vehicle performance information in the vehicle performance memory 21. Correct the performance information.

As described above, the driving skill information updated when the driving skill is improved is input from the IC card reader 11 to the alarm control means 10, and the vehicle performance information corrected based on the surrounding environment is input from the vehicle performance memory 21. .

The alarm control means 10 includes a margin setting means.
Margin information is input from 25, and the margin setting means 25 determines whether the driver should drive carefully or normally based on his / her physical condition etc. and sets it himself. Therefore, if you are tired, etc., drive carefully.

On the other hand, the vehicle is provided with a communication control device,
The communication control circuit 31 gives a transmission instruction to the transmission circuit 32, inputs a signal received by the reception circuit 33, inputs distance / speed information from the distance / speed measurement circuit 34, and displays a signal processing result as a display signal. As well as the distance / speed information to the alarm control means 10.

The transmission circuit 32 receives a transmission instruction from the communication control circuit 1 and transmits a detection signal with directivity in a predetermined direction from the transmission antenna 32a. The receiving circuit 33 receives the ID code signal and outputs the response signal to the receiving antenna 33.
a and outputs it to the communication control circuit 31.

The distance / velocity measuring circuit 34 inputs a signal at the time of transmission of a detection signal from the transmission circuit 32, inputs a signal at the time of arrival of a response signal from the reception circuit 33, and detects a time difference between the two signals and a change in the arrival signal. , The distance between the detection-side moving body and the detection-side moving body and the speed of the detection-side moving body are measured, and the distance / speed information of the measurement result is output to the communication control circuit 31.

The communication control circuit 31 outputs the detection of the detected moving body and information on the distance and speed of the detected moving body to the alarm control means 10. Note that the vehicle has a driving state detecting means 8.
And detects the shift state of the transmission and the ON / OFF state of the turn signal switch together with the vehicle speed and the like, and this operating state information is output to the alarm control means 10 and the communication control circuit 31.

The communication control circuit 31 determines whether or not to transmit a detection signal based on the operation state information. The alarm control means 10 determines whether or not to issue an alarm based on driving state information in addition to the driving skill information, vehicle performance information, margin information, distance / speed information, and the like. A signal is output to the alarm 9.

Hereinafter, how the alarm control is performed will be described for a specific example. As shown in FIG. 2, it is assumed that the vehicle A is about to turn right at the intersection, and the oncoming vehicle B is traveling straight in the oncoming lane. The driver of the vehicle A sets and reads the IC card reader 11 of the vehicle A before driving the IC card 2 which also serves as a license.

When the driver of the vehicle A operates the turn signal lever to make a right turn, the right turn signal switch is turned on and the driving state detecting means 8 detects this, and the communication control circuit 31
Output the detection signal. Upon receiving the signal, the communication control circuit 31 instructs the transmission circuit 32 to transmit a detection signal, and the detection signal is transmitted.

When the oncoming vehicle B receives the detection signal, it returns a response signal. Therefore, the receiving circuit 33 receives the response signal, and the distance / speed measurement circuit 34 determines the oncoming vehicle B based on the detection signal and the response signal. And the speed of the oncoming vehicle B are measured and output to the communication control circuit 31. The communication control circuit 31 outputs distance / speed information of the oncoming vehicle B to the alarm control means 10.

The alarm control means 10 displays the distance / speed information on the display device 35,
From the driving skill information, the vehicle performance information from the vehicle performance memory 21, the driving state information from the driving state detecting means 8, and the margin information from the margin setting means 25, and it is determined whether or not an alarm is issued based on these information. to decide.

If the driver is going to make a right turn, the time required for the right turn to be actually required is calculated from the right turn time of the driver in the driving skill information and the cornering performance of the vehicle in the vehicle performance information. Further, a sufficient right turn request time required for a right turn is calculated by adding an appropriate margin time and the like in consideration of a case where a pedestrian jumps to the right turn destination without depressing the brake on the oncoming vehicle.

On the other hand, the arrival time until reaching the intersection is calculated from information on the distance and the speed to the oncoming vehicle B,
Compare the two.

If the right turn request time is shorter than the arrival time, no alarm is issued because it is possible to make a right turn with a margin, but if the right turn request time is longer than the arrival time, an alarm is issued.

Therefore, the driver of the vehicle A executes a right turn when no alarm is issued, but has no problem, but does not turn right when an alarm is issued. As described above, it is sufficient to drive the vehicle according to the presence or absence of the alarm, and it is possible to prevent the vehicle from driving based on its own probable judgment.

An alarm is not issued except when it is necessary, and an alarm can be issued only when it is really necessary, and the importance of the alarm can be maintained without lowering the recognition of the alarm. For the driver, an alarm is issued by appropriate alarm control in consideration of his / her own driving skills, so that the driver does not deviate from the sense of the driver at all, and the alarm is not bothersome or lost. In addition, since the individual driver's margin information is also taken into account, the driver does not feel uncomfortable following the warning.

The driving skill information is an IC card 2 which is also used as a license.
, The driver can always carry it and use it for different vehicles. Also, the driving skill information stored in the IC card 2 is automatically updated by the updating device 14 when the driving skill increases, so that it is convenient and convenient.

Vehicle performance information includes time of day / night, rain / night, etc.
The correction is performed by the correction unit 24 based on the surrounding environment such as the weather such as fine weather, the road surface friction coefficient, and the like, so that a more appropriate alarm control that always matches the surrounding environment is performed.

The vehicle performance information differs depending on the type of vehicle. The cornering performance and the like differ greatly between a large vehicle and a small vehicle, and even when the vehicle turns a corner at the same vehicle speed, the difference between the entry and the exit of the intersection depends on the total length of the vehicle. The time required is significantly different.

A more specific example is shown in Table 1 below.

[Table 1] Table 1 shows a simplified example of obtaining a right turn request time when making a right turn.

In Example 1 of Table 1 (second column), if the driver's skill is normal and he / she rides in a car and the weather is fine, first, the time required for a right turn is 4 seconds, and the margin set by the driver is Normally, the time required to make a right turn is 8 seconds, which is a total of 3 seconds to allow for the pedestrian to jump right ahead and 1 second to determine the speed of the other vehicle. Is calculated.

If it is rainy, the time required for a right turn is increased by 2 seconds to 6 seconds as in Example 2 of Table 1, and the total time required for a right turn is 10 seconds. In the case of a large vehicle such as a truck, the time required to make a right turn is longer than that of a passenger vehicle (Table 1).
If the careful operation is set, the allowance time is increased by 1 second to 4 seconds (see Example 4 in Table 1).

Although the specific example described above is the alarm control at the time of a right turn, various other alarm controls such as an inter-vehicle distance alarm control and a pop-up alarm control may be executed. In the case of the inter-vehicle distance alarm control or the pop-up alarm control, the control is performed based on the braking time information in the driving skill information.

It should be noted that the alarm by the alarm 9 may be of a type that sounds, a flashing lamp, or a visual appeal.
