[Technical field]
[0001] The present invention relates to a safe driving support system and a program for realizing the safe driving support system. [Background technology]
[0002] Safe driving support systems have been proposed (see, for example, Patent Documents 1 and 2).
[0003] The above-mentioned Patent Document 1 discloses a vehicle control system that controls a vehicle taking into consideration the health condition of the driver. The above-mentioned Patent Document 1 describes that the driver's own biometric information is acquired by a wristband-type body-worn device (wearable terminal) worn by the driver, and it is determined from the driver's biometric information whether the driver's health condition is normal or abnormal, and if the driver's health condition is abnormal, control such as deceleration and stopping of the vehicle is performed.

The above-mentioned Patent Document 2 describes that the driver's blood pressure and pulse are measured by a wristwatch-type portable device (wearable terminal) worn by the driver, and it is determined whether the blood pressure and pulse are normal or abnormal. The above-mentioned Patent Document 2 describes that the above-mentioned determination result and an ID code assigned to each driver are transmitted from the portable device to a vehicle-side processing device, and if the above-mentioned determination result is normal and matches the ID code in the vehicle-side processing device, control is performed to start the engine. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] JP 2016-18474 A [Patent Document 2] JP 2008-36354 A Summary of the Invention [Problem to be solved by the invention]
[0006] As described in Patent Documents 1 and 2 above, a technology is disclosed in which, by using biometric information such as blood pressure and pulse rate obtained by a wearable device worn by the driver, if an abnormality in the driver's health condition is detected, control is performed to stop the vehicle, and if the driver's health condition is normal, control is performed to start the vehicle engine.
[0007] However, if a driver who should be wearing a wearable device does not wear one because it is bothersome or because they are not confident about their health, there is a possibility that a healthy passenger may wear the device in place of the driver and "impersonate" the driver. In such cases, it is difficult to provide support for safe driving.
[0008] The present invention has been made to solve the above problems, and aims to provide a safe driving support system that can support safe driving by preventing spoofing, and a program for realizing the safe driving support system. [Means for solving the problem]
[0009] In order to achieve the above object, the present invention is configured as follows.
[0010] (1) A safe driving support system according to the present invention is a safe driving support system that is worn by a driver of a vehicle and has a terminal environment acquisition unit capable of acquiring information regarding vibration and / or angle at a position where the system is worn on the driver, and is realized by utilizing a communication device with an information communication function, and is characterized in that it has a vehicle-side processing device that is mounted on the vehicle and connected to the communication device so as to be able to communicate information, and the vehicle-side processing device has a vehicle control unit that controls the vehicle, a vehicle-side information communication unit that communicates information with the communication device, a driving state acquisition unit that acquires the vibration and / or angle of the steering wheel on condition that it is detected that the steering wheel of the vehicle is being gripped by the driver, and an impersonation determination unit that acquires information regarding the vibration and / or angle acquired by the terminal environment acquisition unit from the communication device via the vehicle-side information communication unit, compares the vibration and / or angle on the communication device side with the vibration and / or angle on the vehicle-side processing device side, and grants the vehicle control unit permission to drive the vehicle on condition that it is determined that these vibrations and / or angles are synchronized.
[0011] According to the above configuration, it is possible to determine whether or not the steering wheel is being held by the driver wearing the communication device by comparing the vibration and / or angle (steering angle) of the steering wheel of the vehicle acquired by the vehicle-side processing device with the vibration and / or angle at the mounting position of the driver acquired by the communication device to determine whether or not there is synchronization. The reason for this is that the acquired signal (acceleration) of the communication device detected when the driver is holding the steering wheel in the driver's seat is different from the signal acquired when, for example, a passenger is wearing the communication device in the passenger seat. More specifically, the signal is acquired in the driver's seat when the steering wheel is mechanically connected to the tires of the vehicle, while the signal is acquired in the passenger seat when the steering wheel is floating due to the suspension, and the vibration modes are different. As a result, it is possible to prevent spoofing driving by a driver who should be wearing a communication device not wearing the communication device. This makes it possible to support safe driving.
[0012] (2) In the safe driving support system according to the present invention, preferably, the vehicle-side processing device further includes a vehicle start permission determination unit, the communication device further includes a biometric information acquisition unit that acquires biometric information of the driver, and the vehicle start permission determination unit may not permit the vehicle control unit to start the vehicle on condition that the driver is determined to be in a predetermined abnormal state based on the biometric information acquired by the biometric information acquisition unit. With this configuration, the driver cannot drive the vehicle if his / her health condition is abnormal, thereby preventing an abnormal driver from causing an accident.
[0013] (3) In the safe driving support system according to the present invention, it is preferable that the vehicle control unit performs stop control of the vehicle on the condition that the spoofing determination unit compares the vibration and / or angle on the communication device side with the vibration and / or angle on the vehicle side processing device side and determines that they are not synchronized. With this configuration, it is possible to determine that the wearer of the communication device is not holding the steering wheel or is highly likely not to be holding it, based on the presence or absence of synchronization between the vibration and / or angle (steering angle) of the steering wheel of the vehicle and the vibration and / or angle acquired by the communication device. As a result, by performing stop control of the vehicle, it is possible to prevent spoofing driving by a person not wearing the communication device.
[0014] (4) In the safe driving support system according to the present invention, preferably, the vehicle-side processing device further includes a steering sensor for detecting whether the driver is gripping the steering wheel. With this configuration, the state in which the driver is gripping the steering wheel can be easily detected by using the steering sensor.
[0015] (5) In this case, it is preferable that the driving state acquisition unit acquires the vibration and / or angle of the steering wheel on the condition that the steering wheel sensor detects that the driver has been holding the steering wheel for a predetermined period of time. With this configuration, for example, when a passenger in the front passenger seat holds the steering wheel for an instant while wearing a communication device, it is possible to prevent the steering wheel from being erroneously detected as being held by the driver.
[0016] (6) In the safe driving support system according to the present invention, the communication device is preferably a wearable terminal that is attached to the wrist of the driver. With this configuration, the driver can easily wear the wearable terminal as the communication device. Also, by wearing the wearable terminal, the driver's biological information such as heart rate can be easily measured.
[0017] (7) In the safe driving support system according to the present invention, the terminal-side information communication unit and the vehicle-side information communication unit are preferably configured with Bluetooth (registered trademark) and / or Wifi (registered trademark). With this configuration, information (data) related to vibration and / or angle can be easily communicated between the communication device and the vehicle-side processing device by using Bluetooth (registered trademark) and / or Wifi (registered trademark).
[0018] (8) A safe driving support system according to the present invention includes a vehicle-side processing device mounted on a vehicle, and a communication device worn by a driver of the vehicle and capable of communicating with the vehicle-side processing device, the communication device having a terminal environment acquisition unit that acquires vibrations and / or angles at a position where the driver is wearing the communication device, and a terminal-side information communication unit that communicates information with the vehicle-side processing device, and the vehicle-side processing device has a vehicle control unit that controls the vehicle, a vehicle-side information communication unit that communicates information with the terminal-side information communication unit of the communication device, a driving state acquisition unit that acquires the vibrations and / or angles of the steering wheel on condition that it is detected that the steering wheel of the vehicle is being gripped by the driver, and an impersonation determination unit that acquires the vibrations and / or angles acquired by the terminal environment acquisition unit via the terminal-side information communication unit and the vehicle-side information communication unit, compares the vibrations and / or angles on the communication device side with the vibrations and / or angles on the vehicle-side processing device side, and grants the vehicle control unit permission to drive the vehicle on condition that it is determined that these vibrations and / or angles are synchronized.
[0019] According to the above configuration, it is possible to determine whether the steering wheel is being held by the driver wearing the communication device based on the presence or absence of synchronization between the vibration and / or angle (steering angle) of the vehicle steering wheel acquired by the vehicle-side processing device and the vibration and / or angle at the driver's mounting position acquired by the communication device. As a result, it is possible to prevent spoofing of driving by a driver who should be wearing a communication device but is not wearing the communication device. This makes it possible to support safe driving.
[0020] (9) A program of the present invention is a program for realizing a safe driving support system in which a vehicle-side processing device mounted in a vehicle and a communication device worn by a driver are connected to each other so that they can communicate information with each other, and is characterized in that it is capable of realizing the steps of: detecting that the steering wheel of the vehicle is being gripped by the driver; acquiring, in the vehicle-side processing device, a vibration and / or angle of the steering wheel; acquiring, in the communication device, a vibration and / or angle at a mounting position of the communication device worn by the driver; comparing the vibration and / or angle acquired in each of the vehicle-side processing device and the communication device to determine whether they are synchronized; and granting permission for the vehicle to travel on the condition that it is determined that the vibration and / or angle acquired in each of the vehicle-side processing device and the communication device are synchronized. .
[0021] According to the program having the above configuration, it is possible to determine whether or not the steering wheel is being held by the driver wearing the communication device by comparing the vibration and / or angle (steering angle) of the vehicle steering wheel acquired by the vehicle-side processing device with the vibration and / or angle at the driver's wearing position acquired by the communication device to determine whether or not there is synchronization. As a result, it is possible to prevent spoofing of driving by a driver who should be wearing a communication device but is not wearing the communication device. This makes it possible to support safe driving. Effect of the Invention
[0022] According to an aspect of the present invention, it is possible to provide a safe driving support system capable of supporting safe driving by preventing spoofing, and a program for realizing the safe driving support system. [Brief description of the drawings]
[0023] [Figure 1] 1 is a block diagram showing an overall configuration of a safe driving support system according to an embodiment of the present invention; [Diagram 2]4 is a flowchart showing the process of the safe driving support system according to the present embodiment. [Diagram 3] 4 is a flowchart showing the process of the safe driving support system according to the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] The safe driving support system according to the present embodiment will be described below with reference to the accompanying drawings. These drawings are schematic diagrams and are not necessarily drawn to exact scale. In the drawings, like components are denoted by like reference numerals.
[0025] (Overall composition) The overall configuration of a safe driving support system according to this embodiment will be described with reference to FIG.
[0026] As shown in FIG. 1, the safe driving support system 100 according to this embodiment includes a vehicle-side processing device 10 and a communication device 20. The safe driving support system 100 is realized by installing a program for operating the control device constituting the vehicle-side processing device 10 and the communication device 20. As a result, in this embodiment, the vehicle-side processing device 10 acquires vibration and / or angle (steering angle) in the steering wheel of the vehicle, and the communication device 20 acquires vibration and / or angle at the mounting position of the communication device 20 on the driver, and it is determined whether these vibrations and / or angles are synchronized. Next, the vehicle is permitted to travel on the condition that these vibrations and / or angles are synchronized, and the vehicle is controlled to stop on the condition that they are not synchronized. In addition, the communication device 20 acquires biological information such as the driver's heart rate, and the vehicle is controlled not to start (not permitted to start) on the condition that the driver's condition is determined to be abnormal.
[0027] (Vehicle side processing device) The vehicle-side processing device 10 is a device mounted on a vehicle. The vehicle-side processing device 10 includes a control unit 11, a sensor unit 12, and a communication unit 13.
[0028] (Control unit of vehicle side processing device) The control unit 11 is a CPU or the like that controls the entire vehicle-side processing device 10. The control unit 11 includes a vehicle control unit 11a, a driving state acquisition unit 11b, a spoofing determination unit 11c, and a vehicle start permission determination unit 11d.
[0029] The vehicle control unit 11a controls the running, deceleration, stopping, and the like of the vehicle.
[0030] The driving state acquisition unit 11b is mainly composed of an acceleration sensor etc. for acquiring vibration information, and a torque sensor etc. for acquiring steering angle information. The driving state acquisition unit 11b acquires the vibration and / or angle (steering angle) of the steering wheel operated by the driver on the condition that it is detected that the steering wheel of the vehicle is being gripped by the driver. In other words, the driving state acquisition unit 11b acquires at least one of the vibration and angle (steering angle) of the steering wheel.
[0031] The spoofing determination unit 11c acquires the vibration and / or angle acquired by the terminal environment acquisition unit 22a of the communication device 20, which will be described later, via the terminal-side information communication unit 23a and the vehicle-side information communication unit 13a. The spoofing determination unit 11c compares the vibration and / or angle on the communication device 20 side and the vehicle-side processing device 10 side.
[0032] The spoofing determination unit 11c functions as a synchronization determination unit that determines whether the vibration and / or angle on the communication device 20 side and the vibration and / or angle on the vehicle-side processing device 10 side are synchronized. Furthermore, the spoofing determination unit 11c gives permission for the vehicle to travel to the vehicle control unit 11a on the condition that the vibration and / or angle on the communication device 20 side and the vibration and / or angle on the vehicle-side processing device 10 side are determined to be synchronized. Note that "synchronization" may refer not only to the case where the vibration and / or angle on the communication device 20 side and the vibration and / or angle on the vehicle-side processing device 10 side are approximately the same, but also to the case where these vibrations and / or angles are within a predetermined numerical range.
[0033] On the other hand, the spoofing determination unit 11c does not give the vehicle control unit 11a permission to drive the vehicle (performs vehicle stop control) if it determines that the vibration and / or angle on the communication device 20 side and the vibration and / or angle on the vehicle-side processing device 10 side are not synchronized.
[0034] The vehicle start permission determination unit 11d prevents the vehicle from starting by not permitting the vehicle control unit 11a to start the vehicle (not permitting start) on the condition that the driver is determined to be in a predetermined abnormal state based on biometric information acquired by a biometric information acquisition unit 22b of the communication device 20 described later. For example, if there is a predetermined abnormality such as suspected dementia in the daily variation of the biometric information acquired by the biometric information acquisition unit 22b of the communication device 20, the vehicle start permission determination unit 11d does not permit the vehicle control unit 11a to start the vehicle.
[0035] (Sensor part of vehicle side processing device) The sensor unit 12 is mainly composed of a steering sensor 12a. The steering sensor 12a detects whether the driver is holding the steering wheel. The driving state acquisition unit 11b acquires the vibration and / or angle of the steering wheel on the condition that the steering sensor 12a detects that the driver is holding the steering wheel for a predetermined time (for example, about 5 seconds).
[0036] (Communication unit of vehicle side processing device) The communication unit 13 is mainly composed of a vehicle-side information communication unit 13a. The vehicle-side information communication unit 13a transmits and receives various information (data) to and from a terminal-side information communication unit 23a of a communication unit 23 of the communication device 20, which will be described later. The vehicle-side information communication unit 13a is composed of Bluetooth (registered trademark) and / or Wifi (registered trademark), etc.
[0037] (Communication Equipment) The communication device 20 is a watch-type wearable terminal that is worn on the arm or wrist of a driver who drives a vehicle. The communication device 20 is connected to the vehicle-side processing device 10 so as to be able to communicate information. The communication device 20 includes a control unit 21, an acquisition unit 22, and a communication unit 23.
[0038] (Control unit of communication device) The control unit 21 is a CPU or the like that controls the entire communication device 20 .
[0039] (Acquisition unit of communication device) The acquisition unit 22 includes a terminal environment acquisition unit 22a and a biometric information acquisition unit 22b.
[0040] The terminal environment acquisition unit 22a is composed of an acceleration sensor and the like capable of acquiring steering trajectory information and vibration information. The terminal environment acquisition unit 22a acquires vibration and / or angle at a mounting position (for example, a wrist) of a driver in the driver's seat of a vehicle. In other words, the biometric information acquisition unit 22b acquires at least one of vibration and angle. An example of vibration is a vibration specific to a vehicle that is transmitted from the steering wheel or the driver's seat to the communication device 20 because the driver is gripping the steering wheel in the driver's seat. An example of angle is an operation angle (steering angle) caused by the driver gripping the steering wheel in the driver's seat and operating it in the left and right directions. Information (data) related to these vibrations and / or angles is transmitted to the vehicle-side processing device 10 (spoofing determination unit 11c) via the terminal-side information communication unit 23a and the vehicle-side information communication unit 13a.
[0041] The bio-information acquiring unit 22b is a variety of sensors for acquiring bio-information such as the driver's heart rate, temperature, and amount of sweat. The bio-information acquiring unit 22b acquires bio-information by measuring the driver's bio-information with a sensor contact surface in contact with the contact surface with the driver (skin of the wrist in this embodiment). Information (data) related to the driver's bio-information is transmitted to the vehicle-side processing device 10 (vehicle start permission determining unit 11d) via the terminal-side information communicating unit 23a and the vehicle-side information communicating unit 13a.
[0042] (Communication unit of communication device) The communication unit 23 is mainly composed of a terminal-side information communication unit 23a. The terminal-side information communication unit 23a transmits and receives various information (data) to and from the vehicle-side information communication unit 13a of the communication unit 13 of the vehicle-side processing device 10. The terminal-side information communication unit 23a is composed of Bluetooth (registered trademark) and / or Wifi (registered trademark), etc.
[0043] (Safety driving support system processing) The process of the safe driving support system according to this embodiment will be described with reference to FIGS.
[0044] 2, in step S10, it is detected that the driver is wearing the communication device 20 (wearable terminal). Also in step S10, it is detected by a steering grip sensor and a steering torque sensor (not shown) that the driver is gripping the steering wheel. Then, the process proceeds to step S11.
[0045] In step S11, biometric information such as the driver's heart rate is acquired by the biometric information acquisition unit 22b of the communication device 20. The communication device 20 transmits the driver's biometric information to the vehicle start permission determination unit 11d via the terminal side information communication unit 23a and the vehicle side information communication unit 13a. The vehicle start permission determination unit 11d determines whether the driver is in a normal state or an abnormal state based on the biometric information acquired by the biometric information acquisition unit 22b.
[0046] If it is determined in step S11 that the driver is in a normal state (Yes), the process proceeds to step S12. On the other hand, if it is determined in step S11 that the driver is in an abnormal state (No), the process proceeds to step S13 (see FIG. 3).
[0047] In step S12, a communication determination is made in the communication device 20 and the vehicle-side processing device 10 (whether or not communication is occurring within the range of the driver's seat). If it is determined in step S12 that communication is occurring within the range of the driver's seat (Yes), the process proceeds to step S14. On the other hand, if it is determined in step S12 that communication is not occurring within the range of the driver's seat (No), the process proceeds to step S13 (see FIG. 3).
[0048] As shown in Fig. 3, in step S13, the vehicle control unit 11a judges whether the vehicle is in a traveling state. If the vehicle control unit 11a judges in step S13 that the vehicle is in a traveling state (Yes), the process proceeds to step S15. In step S15, the vehicle control unit 11a performs control such as an alert and / or vehicle stop. Then, the process returns to step S11 (see Fig. 2).
[0049] On the other hand, if the vehicle control unit 11a determines in step S13 that the vehicle is not in a running state (No), the process proceeds to step S16. In step S16, the vehicle control unit 11a performs control such as starting the I / G (ignition) and / or disabling the vehicle from being unlocked (unlocking not permitted), and the driver enters a standby state. Then, the process returns to step S11 (see FIG. 2).
[0050] 2, in step S14, the vehicle start permission determination unit 11d permits the start of the vehicle, and the vehicle control unit 11a starts the engine when the driver performs an engine start operation. Then, the process proceeds to step S17.
[0051] In this embodiment, in step S17, the vibration and / or angle acquired by the terminal environment acquisition unit 22a of the communication device 20 is compared with the vibration and / or angle (steering angle) acquired by the driving state acquisition unit 11b of the vehicle-side processing device 10, and if it is determined that at least one of these vibrations and angles is synchronized (matches), the process proceeds to step S19. Note that the order of the processes in steps S17 and S18 may be reversed.
[0052] Specifically, prior to the processing in steps S17 and S18, information (data) regarding the vibration and / or angle acquired by the terminal environment acquisition unit 22a of the communication device 20 is transmitted to the impersonation determination unit 11c of the vehicle-side processing device 10 via the terminal-side information communication unit 23a and the vehicle-side information communication unit 13a.
[0053] In step S17, the spoofing determination unit 11c compares the magnitude of the angle on the communication device 20 side with the magnitude of the angle (steering angle) on the vehicle-side processing device 10 side. Permission to drive the vehicle is given to the vehicle control unit 11a on the condition that the magnitudes of these angles are synchronized, specifically, that the amount of change in angle per unit time is substantially the same at a certain timing (Yes), for example. This allows the driver to drive the vehicle. Then, the process proceeds to step S19.
[0054] On the other hand, if the spoofing determination unit 11c determines that the magnitudes of these angles are not synchronized (No), the process proceeds to step S18.
[0055] In step S18, the spoofing determination unit 11c compares the magnitude of the vibration on the communication device 20 side with the magnitude of the vibration on the vehicle-side processing device 10 side. In step S18, on the condition that the spoofing determination unit 11c determines that these vibrations are synchronized (Yes), permission to drive the vehicle is given to the vehicle control unit 11a. This allows the driver to drive the vehicle. Then, the process proceeds to step S19.
[0056] In step S18, if the spoofing determination unit 11c determines that the magnitudes of these vibrations are not synchronized (No), the vehicle control unit 11a is not given permission to drive the vehicle (driving not permitted). Then, the process proceeds to step S20.
[0057] In step S20, the vehicle control unit 11a performs control such as issuing an alert and / or stopping the vehicle, etc. Then, the process returns to step S17.
[0058] In step S19, the vehicle control unit 11a controls the running state of the vehicle (continues running), and then the process proceeds to step S21.
[0059] In step S21, the vehicle control unit 11a determines whether the I / G has been stopped (OFF). If the I / G has not been stopped (No) in step S21, the process returns to step S11. On the other hand, if the I / G has been stopped (Yes) in step S21, the process ends this control.
[0060] According to the embodiment described above, the following advantages (1) to (7) can be obtained.
[0061] (1) In the safe driving support system 100 according to the above embodiment, the vibration and / or angle on the communication device 20 side is compared with the vibration and / or angle (steering angle) on the vehicle side processing device 10 side, and permission to drive the vehicle is given to the vehicle control unit 11a on the condition that the masquerading determination unit 11c determines that these vibrations and / or angles are synchronized.
[0062] According to the above embodiment, it is possible to determine whether the steering wheel is being gripped by the driver wearing the communication device 20, based on the presence or absence of synchronization between the vibration and / or angle (steering angle) of the steering wheel of the vehicle acquired by the vehicle-side processing device 10 and the vibration and / or angle at the mounting position of the driver acquired by the communication device 20 (wearable terminal). The reason for this is that the acquired signal (acceleration) of the communication device 20 detected in a state where the driver is gripping the steering wheel in the driver's seat is different from the signal acquired in a state where the passenger wears the communication device 20 in the passenger seat, for example. More specifically, the signal is acquired in a state where the steering wheel is mechanically connected to the tires of the vehicle in the driver's seat, while the signal is acquired in a state where the steering wheel is floating due to the suspension in the passenger seat, and the vibration modes are different. As a result, it is possible to prevent spoofing driving by a driver who should wear the communication device 20 not wearing the communication device 20. This makes it possible to support safe driving.
[0063] (2) In the safe driving support system 100 according to the above embodiment, the vehicle control unit 11a is not permitted to start the vehicle on the condition that the vehicle start permission determination unit 11d determines that the driver is in a predetermined abnormal state based on the driver's biometric information acquired by the biometric information acquisition unit 22b. This prevents the driver from driving the vehicle if his / her health condition is abnormal, thereby preventing an abnormal driver from causing an accident.
[0064] (3) In the safe driving support system 100 according to the above embodiment, the vehicle control unit 11a performs stop control of the vehicle on the condition that the spoofing determination unit 11c determines that the vibrations and / or angles (steering angle) on the communication device 20 side are not synchronized as a result of comparing the vibrations and / or angles (steering angle) on the vehicle side processing device 10 side. This makes it possible to determine that the wearer of the communication device 20 is not holding the steering wheel (is highly likely not to be holding it) based on the presence or absence of synchronization between the vibrations and / or angles (steering angle) of the steering wheel of the vehicle and the vibrations and / or angles acquired by the communication device 20. As a result, by performing stop control of the vehicle, it is possible to prevent spoofing driving by a person not wearing the communication device 20.
[0065] (4) In the safe driving support system 100 according to the above embodiment, the steering sensor 12a detects whether the driver is holding the steering wheel. This makes it possible to easily detect the state in which the driver is holding the steering wheel by using the steering sensor 12a.
[0066] (5) In the safe driving support system 100 according to the above embodiment, the driving state acquisition unit 11b acquires the vibration and / or angle of the steering wheel on the condition that the steering wheel sensor 12a detects that the driver has been holding the steering wheel for a predetermined period of time. This prevents, for example, a passenger in the front passenger seat holding the steering wheel for an instant while wearing the communication device 20 from being erroneously detected as holding the steering wheel by the driver.
[0067] (6) In the safe driving support system 100 according to the above embodiment, a wearable device attached to the wrist of the driver is used as the communication device 20. This allows the driver to easily wear the wearable device as the communication device 20. In addition, by wearing the wearable device, it is possible to easily measure biological information such as the driver's heart rate.
[0068] (7) In the safe driving support system 100 according to the above embodiment, the terminal-side information communication unit 23a and the vehicle-side information communication unit 13a are configured using Bluetooth (registered trademark) and / or Wifi (registered trademark). This makes it possible to easily communicate information (data) related to vibration and / or angle between the communication device 20 and the vehicle-side processing device 10 by using Bluetooth (registered trademark) and / or Wifi (registered trademark).
[0069] (Modification) The above embodiment can be modified as follows.
[0070] In the above embodiment, an example was shown in which the presence or absence of comparison and synchronization was determined for the vibration and / or angle (steering angle) on the communication device side and the vehicle side processing device side, but the present invention is not limited to this. In the present invention, it is also possible to obtain other information in addition to the vibration and / or angle and determine the presence or absence of comparison and synchronization.
[0071] In the above embodiment, a wearable terminal is used as an example of a communication device, but the present invention is not limited to this. The present invention can be applied to a communication device other than a wearable terminal as long as the communication device can be worn by a driver.
