DETAILED DESCRIPTION OF THE INVENTION

[0012] FIG. 1 is a diagram showing an embodiment of a driver's mobile phone use detection device according to the present invention. It is installed and used in front of the driver's seat of a vehicle. The driver's mobile phone use detection device 1000 includes a functional unit 100 and a power supply unit 200 that supplies power to the functional unit 100. The functional unit 100 includes a control means 110, and a moving speed detection means 120 that detects the moving speed (the same as the vehicle's moving speed by mounting) and determines whether the vehicle is moving at a running or a speed equal to or higher than a predetermined value, or is moving at a stop or a speed lower than the predetermined value. When the vehicle is moving at a running or a speed equal to or higher than a predetermined value, a driver's mobile phone use detection means 130 that acquires an image of the driver and detects whether the driver is holding a mobile phone or not (means such as image recognition or artificial intelligence image recognition from the image is preferable), and determines a violation when holding, and no violation when not holding, and a mobile phone use storage means 140 that stores data of the violation image. More preferably, a notification means 150 that performs necessary notifications to the driver, which is controlled by the control means 110, and a call suspension setting means 160 that sets a call suspension time from when the driver's image is acquired by the driver's mobile phone use detection means 130 to when it is stored in the mobile phone use storage means 140 as a violation and gives a suspension at the time of determination. More preferably, when there is no power supply from the power supply unit 200, an internal auxiliary power supply 170 that supplies power to the functional unit 100, and even when there is no power supply from the power supply unit 200 to the functional unit 100, power is supplied from the internal auxiliary power supply 170, a power removal is detected, and a power removal response means 180 that causes the driver's mobile phone use detection means 130 to acquire an image of the driver (in this case, it may be irrelevant to running, stopping, or speed) is provided.

[0013] ​ Furthermore, it is extremely effective to provide a voice acquisition means 130B such as a microphone to acquire the voice of the driver and activate the driver mobile phone use detection means 130 when there is voice. Furthermore, it is preferable to have a communication means 190 for transmitting and receiving data of the violation reflection image in the mobile phone use storage means to / from an external management center or the like. In this figure, the power supply unit 200 preferably obtains power from the vehicle power supply 220 via a power switch 210 that is turned on and off in conjunction with the vehicle driving key, but this is not restrictive. As an example of this example, taking power from a so-called cigarette power inlet can be mentioned. Naturally, it is possible to use another power source as the main power source instead of the vehicle power supply 220 for the power supply unit 200.

[0014] Furthermore, as the moving speed detection means 120, means for obtaining from the movement of the position at each time by GPS (Global Positioning System), means for obtaining the speed by integrating the values from an accelerometer, means using an inclination sensor whose inclination changes according to the speed, etc. can be used. A camera can be used for image acquisition of the driver mobile phone use detection means 130.

[0015] As the power removal countermeasure means 180, the following can be used. FIG. 4 is a diagram showing an embodiment of the power removal countermeasure means for power removal of the driver mobile phone use detection device according to the present invention. The power supply unit 200 has a vehicle power supply 220 as the main power source and always supplies power to the functional unit 100. However, the functional unit 100 has an internal auxiliary power source 170 that substitutes for the supply when the main power source cannot be supplied and a power removal countermeasure means 180 that detects power removal. Always, the power removal countermeasure means 180 is in a state where power is supplied by the internal auxiliary power source 170 and operates. In this example, it is a resistor 421 connected in parallel to the internal auxiliary power source 170 and a switch 422 that connects between electrical terminals by movement due to removal. In this example, when there is no power disconnection, the electrical terminals of the switch 422 are in a non-connected state via the switch connection piece 422b. When there is a power disconnection, the electrical terminals of the switch 422 are in a connected state. Therefore, the potential at the connection point P between the resistor 421 and the switch 422 is equal to the potential of the internal auxiliary power supply 170 when there is no power disconnection, and is equal to the reference zero potential when there is a power disconnection. In this example, the presence or absence of power disconnection is grasped as a change in the potential at the connection point P and is used for subsequent countermeasures. For example, when driving the functional unit 100 with the internal auxiliary power supply 170 instead of the vehicle power supply 220, the gate of the transistor 430 is driven by the signal at the connection point P. In this case, the transistor 430 is turned on by the zero potential at the connection point P, and power is supplied from the internal auxiliary power supply 170 to the functional unit 100 and used. Also, based on the potential at the connection point P or the electrical signal derived and driven thereby, countermeasures against power disconnection violations such as driver video acquisition and audio notification are carried out. Of course, if corresponding to power disconnection, the change in potential may follow the reverse logic. In addition, for example, a cigarette power supply is shown that includes a switch 422 for detecting insertion and removal between a vehicle power output terminal 440 and a plug-in input terminal 450 that is inserted into and removed from it. In Figure 4-A, with the plug-in input terminal 450 inserted into the vehicle power output terminal 440, the electrical terminals of the switch 422 are in a non-connected state via the switch connection piece 422b. In Figure 4-B, due to removal, the electrical terminals 422 are in a connected state via the switch connection piece 422b.

[0016] In addition, the power disconnection countermeasure means 420 can have many countermeasures as follows, in addition to being composed of a resistor and an electrical contact that mechanically moves to connect between terminals as in this example. For example, those using a magnet attached near the vehicle power output terminal 440 and a magnetic sensor provided on the plug-in input terminal 450 side, those using a mark (such as a QR code (registered trademark)) attached to the vehicle power output terminal 440 side and a mark reading means provided on the plug-in input terminal 450 side, those using a light reflecting plate or light projecting means attached to the vehicle power output terminal 440 side and a light projecting / receiving means or a light receiving means provided on the plug-in input terminal 450 side, etc. can be mentioned.

[0017] Figure 2 is a diagram showing an embodiment of the usage state in the driving environment of the driver's mobile phone usage detection device according to the present invention. The driver's mobile phone usage detection device is installed on the driving platform, on the ceiling or side wall in front of the driver's seat in a state where it can acquire the image of the driver, because it acquires the image of the driver when the driver uses the mobile phone while driving, and determines whether it is "driving while" and takes corresponding measures.

[0018] Figure 3 is a diagram showing an embodiment of the operation flow of the driver's mobile phone usage detection device according to the present invention. 1) Turn on the power and operate the device of the driver's mobile phone usage detection device 1000. It is preferable that this is interlocked with the engine start of the vehicle. 2) Compare and determine the traveling speed with the preset conditions If it is stopped or slower than the preset conditions, return to 2) and repeat at a predetermined time interval. If it is traveling or faster than the preset conditions, 3) When passing through the step of determining the presence or absence of speech, if there is no speech, return to 2) and repeat at a predetermined time interval. When there is speech and when not passing through the step of determining the presence or absence of speech, 4) Detect the driver's mobile phone usage (acquire the driver's image), 5) Determine the presence or absence of the driver's use of the mobile phone in the image. If there is no use, return to 2) and repeat at a predetermined time interval. If there is use, 6) Count the remaining call time, 7) After the remaining call time, give a notification such as "Mobile phone use has been confirmed. You are driving. Please do not use the mobile phone." In some cases, 8) Determine whether the number of notifications or the time is within the specified value, If it is within the specified value, return to 2) and repeat at a predetermined time interval. If it exceeds the preset value, 9) Record the violation of mobile phone use, (record the violation time, violation evidence image, violator name, etc. in the mobile phone use recording means 140.) Return to 2) and repeat at a predetermined time interval. In addition, it is also possible to send the memory data for use in analyzing violators and guiding violators.
