FIG. 4 is a schematic flow chart showing the first embodiment of the processing procedure of the doze accident prevention system.

First, the driver actuates the drowsiness prevention device with the start button provided on the shift lever, and during operation, randomly emits a sound (can be muted) from the light emitter and speaker of the drowsiness prevention device at predetermined intervals. The perceptual signal is emitted (step 101). The driver responds to these perceptual signals with a confirmation button, and based on the reaction time measured by the measurement processing unit (step 102),
The determination processing unit determines the degree of dozing (step 10
3).

When it is determined in step 103 that the driver's reaction is normal, steps 101 to 103 are repeated until the driver arrives at a rest place (parking or the like), and the driver's condition is continuously monitored.

If there is a reaction from the driver, but the reaction speed is slow and it is determined that there is a high possibility of falling asleep, the time until the next signal (interval of signal transmission) is shortened and the driver is in a dozing state. A caution mode is entered to check more carefully whether or not (step 104). The attention mode is set in multiple stages, and as the reaction speed is slower and the risk of falling asleep is determined to be higher, the signal interval is shortened, more signals are output, and the drowsiness level is determined based on the reaction. This is a mode for examining in more detail.

In step 103, there is no driver's reaction (no confirmation operation), or in step 105
If it is determined that the reaction time is slow and the drowsiness risk is very high, the pre-stored voice warning message, such as "There is a drowsiness risk. Contact the operator. Please wake up "from the speaker to wake up the driver (Step 10
6).

Thereafter, similarly, a sensory signal is transmitted and the reaction speed thereof is measured. If the reaction is normal in the determination in step 107 and there is no possibility of falling asleep, the process returns to step 101 and the sound and light are transmitted to the resting place by the above-mentioned sound and light. The signal is repeated.

If it is judged in step 107 that there is no reaction despite the above-mentioned call and the danger of falling asleep is high, a warning sound from a speaker, vibration by an oscillator,
The driver is awakened by a warning light from the light emitting device or the like (step 108), and in parallel with this, the notification processing unit of the doze prevention device automatically dials the security center together with the danger information (step 109). Information on the current position measured by the current position measuring unit of the doze prevention device is added to the danger information.

The support computer of the security center which has received the danger information displays the vehicle position grasped by the position recognition processing unit on the basis of the position information and the resting place in the vicinity thereof (step 110), and by both call means. Allows interaction between the operator and the driver.

The operator confirms the physical condition of the driver, for example, "Hello, Mr. XX (driver), how are you?", And confirms with the driver based on the rest place displayed on the display. Smoothly guides the vehicle to an appropriate resting place such as parking (step 111). Such a dialogue with the operator has a wakefulness effect from a dozing,
The effect of the security and flexibility that the other person is a human being,
It is possible to guide and support safer driving in dangerous situations such as dozing.

Before driving, it is preferable that the driver is provided with a driving schedule and necessary information created in advance by the support computer of the security center, and the contact time is set according to the health condition of the driver.
Further, in the flow chart of this example, the call with the operator is made after step 109 where the risk of drowsiness is high. However, even when the driver is awake, the driver realizes that he / she is tired and takes a rest place. When you want to know or get other information, you can voluntarily talk with the operator at the center using the call button. Conversely, the operator will provide various information such as road traffic information as appropriate. It is also preferable to Furthermore, after arriving at the resting place,
It is preferable that the center contact the driver at an appropriate wake-up time.

Next, a second embodiment of the processing procedure of the doze accident prevention system will be described.

In the above-mentioned first embodiment, basically, the procedure in which the operator of the security center can safely guide the user to the resting place while interacting with the driver by receiving the danger information from the drowsiness prevention device has been explained. In addition to this, the example is an example in which an operation schedule from departure to arrival at the destination is assembled, and operation is generally supported according to the operation schedule by a call with an operator.

The driver operates the drowsiness prevention device with the start button provided on the shift lever, and first, before the operation, talks with the operator of the security center using the call button to make a schedule meeting. This driving schedule is created based on the driving schedule and physical condition of the driver of the day, as will be described later.

As shown in FIG. 5, the call button is pressed to connect to the security center, and the driver's name, telephone number, personal information such as affiliated company, and scheduled operation schedule (destination, etc.) are guided by the operator. , The physical condition (“especially sleepy”, “still OK”, “normal”, etc.) is transmitted (step 201), and the operator creates an operation schedule. Specifically, the operation schedule data and the information on the health condition obtained from the driver are input to the support computer from the input device (step 20).
2), the support computer causes the schedule processing unit to create a driving schedule based on the input data and the road condition managed by the road information storage unit (step 203).

The created driving schedule is output to the display (step 204), and the operator gives the following voice guidance based on the displayed driving schedule (step 205), and at the same time provides road traffic information (step 205). Step 206). "How about a break at XX parking after XX minutes?""I will call you at XX.""There is no accident or construction at this time.""If there is a sign of dozing, the operation button Please press to contact us. "" Any other questions etc. "" Then, please drive safely. "

During operation, step 1 shown in FIG. 4 described above.
Similar to 01-111, the drowsiness prevention device mounted on the vehicle determines the drowsiness level of the driver, wakes up based on the result, notifies the center of the danger information, and the above-mentioned guidance of the operator is performed to this. . In addition, during the operation of the vehicle, the operator contacts the driver based on the created driving schedule, the course, and the current position of the vehicle when the break time approaches, and appropriately provides information such as road traffic information.

That is, before the break time, the operator at the center talks with the driver to prompt a break and guide a proper parking area as follows, for example. "It's time for a break.""I'm currently driving in ○○, so how about a break in the ○○ parking area?"

The current position of the vehicle can be grasped by receiving the vehicle position information measured by the GPS receiving device from the doze prevention device to the supporting computer of the center at all times or periodically, and the supporting computer can grasp the grasped vehicle position. Is managed by the vehicle information storage unit, and the vehicle position and a resting place in the vicinity thereof are displayed on the display, and the operator is guided based on this.

If the arrival of the vehicle at the resting place is confirmed by a call or position information, the support computer sets the time of wake-up or the end of the rest according to the operation schedule of the vehicle, and the operator based on this set the driver. For example, the rest guidance is given as follows. "Turn off the snooze prevention device.""Then, I will contact you at XX."

When it is time to wake up or end the break, the operator communicates with the driver to make a contact to that effect and to make a schedule meeting regarding the subsequent operation, and also provides road traffic information. , The drowsiness prevention device is started again, and the above procedure is repeated.

As described above, in this example, not only when there is a high risk of drowsiness, but also safe driving is always supported in accordance with the driving schedule created based on the physical condition of the driver from the start to the destination. Dozing driving which causes an accident is prevented.
