Embodiments for Carrying Out the Invention

[0024] Hereinafter, embodiments of a driver monitoring device, a driver monitoring system (hereinafter referred to as a system), a driver monitoring method, and a program according to the present invention will be described with reference to the accompanying drawings.

[0025] As shown in FIG. 1, the system 10 of the present embodiment includes a vehicle 20, an external server (driver monitoring device) (computer) 30, a mobile terminal (terminal device) (computer) 40, and a mobile terminal 50.

[0026] The vehicle 20, which can communicate data with the external server 30 and the mobile terminals 40 and 50 via a network, has an ECU (Electronic Control Unit) 21, a wheel speed sensor 22, an accelerator opening sensor 23, a brake pedal force sensor 24, a steering angle sensor 25, a camera 26, and a GPS (Global Positioning System) receiver 27 as shown in FIG. 1. The wheel speed sensor 22, the accelerator opening sensor 23, the brake pedal force sensor 24, the steering angle sensor 25, the camera 26, and the GPS receiver 27 are connected to the ECU 21.

[0027] Four wheel speed sensors 22 are provided on the vehicle 20. Each wheel speed sensor 22 detects the wheel speeds of the four wheels respectively. The accelerator opening sensor 23 detects the accelerator opening. The brake pedal force sensor 24 detects the brake pedal force input by the driver Dr, who is the person to be monitored, to a brake pedal (not shown). The steering angle sensor 25 detects the steering angle of a steering wheel (not shown). The GPS receiver 27 acquires information regarding the position where the vehicle 20 is traveling (hereinafter referred to as "position information") by receiving GPS signals transmitted from GPS satellites. The detection values detected by the wheel speed sensor 22, the accelerator opening sensor 23, the brake pedal force sensor 24, the steering angle sensor 25, and the GPS receiver 27 every time a predetermined time elapses are transmitted to the ECU 21 via a CAN (Controller Area Network) provided in the vehicle 20 and stored in a storage 21D of the ECU 21 described later while being associated with time information. Furthermore, the camera 26 repeatedly captures the face of the driver Dr sitting in the driver's seat (not shown) of the vehicle 20 every time a predetermined time elapses. The image data acquired by the camera 26 is transmitted to the ECU 21 via a network provided in the vehicle 20 and stored in the storage 21D while being associated with the position information and the time information.

[0028] As shown in FIG. 2, the ECU (computer) 21 is composed of a CPU (Central Processing Unit: processor) 21A, a ROM (Read Only Memory) 21B, a RAM (Random Access Memory) 21C, a storage 21D, a wireless communication I / F (Inter Face) 21E, and an input / output I / F 21F. The CPU 21A, ROM 21B, RAM 21C, storage 21D, wireless communication I / F 21E, and input / output I / F 21F are communicably connected to each other via a bus 21Z. The CPU 21A can acquire information regarding the date and time from a timer (not shown).

[0029] The CPU 21A is a central processing unit that executes various programs and controls each part. That is, the CPU 21A reads a program from the ROM 21B or the storage 21D and executes the program using the RAM 21C as a working area. The CPU 21A performs control of each component and various arithmetic processes (information processing) according to the programs recorded in the ROM 21B or the storage 21D.

[0030] The ROM 21B stores various programs and various data. The RAM 21C temporarily stores a program or data as a working area. The storage 21D is composed of a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs and various data.

[0031] The wireless communication I / F 21E is an interface for wireless communication with various devices. For example, the wireless communication I / F 21E can perform wireless communication with an external server 30 and a mobile terminal 40 via a network (for example, the Internet).

[0032] FIG. 3 shows an example of the functional configuration of the ECU 21 in a block diagram. The ECU 21 includes, as its functional components, a wakefulness estimation unit 201, a PCS control unit 202, and a communication control unit 203. These functions are realized by the CPU 21A reading and executing a program stored in the ROM 21B.

[0033] The wakefulness estimation unit 201 determines the wakefulness of the driver Dr based on the state of the driver Dr's eyes and the like included in the image data captured by the camera 26. The "wakefulness" in this specification includes the wakefulness level when a person is awake and the sleep level (sleep depth) when a person is in a sleeping state. The sleep level (sleep depth) is defined in five levels. The deeper the driver Dr is asleep, the larger the number of the sleep level (sleep depth). Sleep level 1 corresponds to REM sleep. Sleep levels 2 to 5 correspond to non-REM sleep. When the sleep level is equal to or higher than a predetermined level, the wakefulness estimation unit 201 determines that the driver Dr is drowsy driving, and records the drowsiness detection information indicating this determination result in the storage 21D while associating it with the position information and the time information. An example of the predetermined level is sleep level 1.

[0034] The PCS control unit 202 has a function of controlling the PCS (Pre Crash Safety system) mounted on the vehicle 20. That is, when a predetermined condition is satisfied, the brake actuator of the brake device (not shown) of the vehicle 20 is controlled to generate a braking force in the brake device. When the PCS is activated, the PCS control unit 202 records the PCS activation information indicating this in the storage 21D while associating it with the position information and the time information.

[0035] The communication control unit 203 controls the wireless communication I / F 21E. The wireless communication I / F 21E controlled by the communication control unit 203 wirelessly transmits the information regarding each detected value, the image data, the drowsiness detection information, and the PCS activation information recorded in the storage 21D to the external server 30 every predetermined time. Hereinafter, the information regarding each detected value, the image data, the drowsiness detection information, and the PCS activation information may be collectively referred to as vehicle-related information (vehicle information).

[0036] As shown in FIG. 2, the external server 30 includes a CPU 31A, a ROM 31B, a RAM 31C, a storage 31D, a wireless communication I / F (vehicle information acquisition unit) (transmission unit) 31E, and an input / output I / F 31F. The CPU 31A, the ROM 31B, the RAM 31C, the storage 31D, the wireless communication I / F 31E, and the input / output I / F 31F are communicably connected to each other via a bus 31Z. The CPU 31A, the ROM 31B, the RAM 31C, the storage 31D, the wireless communication I / F 31E, and the input / output I / F 31F have functions corresponding to those of the CPU 21A, the ROM 21B, the RAM 21C, the storage 21D, the wireless communication I / F 21E, and the input / output I / F 21F, respectively. Note that map data is recorded in the storage 31D. This map data includes information representing at least one danger area (first area). Note that areas other than the danger area are safe areas.

[0037] FIG. 4 shows an example of the functional configuration of the external server 30 in a block diagram. The external server 30 has, as a functional configuration, a diagnosis unit 301, a special condition determination unit 302, a mode determination unit 303, a mode control unit 304, and a communication control unit (information control unit) 305. These functions are realized by the CPU 31A reading and executing a program stored in the ROM 31B.

[0038] The diagnostic unit 301 performs a driving diagnosis based on the vehicle-related information received by the wireless communication I / F 31E from the vehicle 20. For example, as disclosed in Japanese Unexamined Patent Application Publication No. 2019-12481 and Japanese Unexamined Patent Application Publication No. 2020-95403, the method of performing a driving diagnosis based on the above vehicle-related information is well known. The method of performing a driving diagnosis in the present invention may be any method. For example, the diagnostic unit 301 performs a driving diagnosis on the accelerator operation based on the detected value of the accelerator opening sensor 23 and the detected value of the wheel speed sensor 22, performs a driving diagnosis on the brake operation based on the detected value of the brake pedal force sensor 24 and the detected value of the wheel speed sensor 22, and performs a driving diagnosis on the steering operation based on the detected value of the steering angle sensor 25. Further, the diagnostic unit 301 determines whether or not the vehicle speed of the vehicle 20 exceeds the speed limit based on the information on the speed limit of each road included in the map data recorded in the storage 31D, the position information of the vehicle 20, and the detected value of the wheel speed sensor 22. Further, the diagnostic unit 301 calculates scores for the accelerator operation, the brake operation, and the steering operation based on these driving diagnosis results. Further, the diagnostic unit 301 records these diagnostic results (vehicle information) in the storage 31D. At this time, the diagnostic unit 301 records each diagnostic result in the storage 31D while associating it with the position information and time information of the vehicle 20.

[0039] The special condition determination unit 302 determines whether or not a predetermined special condition is satisfied. The special condition is satisfied when at least one of the following conditions 1 to 3 is satisfied. Condition 1: When a family member (a person other than the driver Dr) Fm of the driver Dr uses the mobile terminal 40 to send an emergency notification request to the external server 30. Condition 2: When at least one of the drowsiness detection information and the PCS activation information is included in the vehicle-related information received by the external server 30 from the vehicle 20. Condition 3: When it is determined based on the position information transmitted from the vehicle 20 that the vehicle 20 is traveling in a danger area preset in the map data.

[0040] The mode determination unit (specific information determination unit) 303 sets the usage mode of the vehicle 20 and determines whether the usage mode is the privacy mode. In the present embodiment, based on the information input using an input device (not shown) provided in the external server 30, the mode determination unit 303 determines the usage mode and the contents of the first list 33 and the second list 35 described later. The usage mode of the vehicle 20 in the present embodiment is set to the privacy mode. In the storage 31D, data indicating that the usage mode of the vehicle 20 is the privacy mode is recorded.

[0041] The mode control unit 304 prohibits the vehicle 20 from entering the privacy mode when a special condition is satisfied. That is, while the special condition is satisfied for the vehicle 20, the mode control unit 304 releases the privacy mode of the vehicle 20. Further, when the special condition is no longer satisfied for the vehicle 20, the mode control unit 304 resets the usage mode of the vehicle 20 to the privacy mode.

[0042] The first list 33 shown in FIG. 5 and the second list 35 shown in FIG. 6 are recorded in the storage 31D. The first list 33 defines the relationship between the content of the vehicle-related information of the vehicle 20 and the attribute of each vehicle-related information. As shown in FIG. 5, the position information and drowsiness detection information is specific information, PCS operation information and the vehicle speed information is general information. The second list 35 defines the relationship between each item of the driving diagnosis generated by the diagnosis unit 301 and the attribute of each item. As shown in FIG. 6, the item related to speed violation is specific information, and the items related to the accelerator operation, the brake operation, and the steering operation are general information.

[0043] The communication control unit 305 controls the wireless communication I / F 31E. The data received by the wireless communication I / F 31E from the vehicle 20 is recorded in the storage 31D. Further, the wireless communication I / F 31E controlled by the communication control unit 305 transmits various data recorded in the storage 31D to the mobile terminal 40 based on the first list 33 and the second list 35. When the vehicle 20 is set to the privacy mode, the wireless communication I / F 31E generally does not transmit the specific information defined in the first list 33 and the second list 35 to the mobile terminal 40. On the other hand, regardless of whether the vehicle 20 is set to the privacy mode or not, the wireless communication I / F 31E transmits the general information defined in the first list 33 and the second list 35 to the mobile terminal 40. Thus, the type of data transmitted from the wireless communication I / F 31E to the mobile terminal 40 changes according to whether the usage mode is set to the privacy mode or not.

[0044] The mobile terminal 40 shown in FIG. 1 includes a CPU, a ROM, a RAM, a storage, a wireless communication I / F, and an input / output I / F. The mobile terminal 40 is, for example, a smartphone or a tablet computer. The CPU, ROM, RAM, storage, wireless communication I / F, and input / output I / F of the mobile terminal 40 are communicably connected to each other via a bus. The mobile terminal 40 can acquire information regarding the date and time from a timer (not shown). The mobile terminal 40 is provided with a display unit 41 having a touch panel. As shown in FIG. 1, the mobile terminal 40 is owned by one of the family members Fm of the driver Dr. A predetermined driving information display application is installed in the mobile terminal 40. Further, map data is recorded in the storage of the mobile terminal 40.

[0045] FIG. 7 shows an example of the functional configuration of the mobile terminal 40 in a block diagram. The mobile terminal 40 has, as a functional configuration, a communication control unit 401 and a display unit control unit 402. The communication control unit 401 and the display unit control unit 402 are realized by the CPU reading and executing a program stored in the ROM.

[0046] The communication control unit 401 controls the wireless communication I / F.

[0047] The display control unit 402 controls the display unit 41. That is, the display control unit 402 causes the display unit 41 to display, for example, information received by the mobile terminal 40 from the vehicle 20 or the external server 30 and information input via the touch panel. The information input by the touch panel of the display unit 41 can be transmitted by the wireless communication I / F to the vehicle 20, the external server 30, and the mobile terminal 50.

[0048] Furthermore, the driver Dr has the mobile terminal (specific information determination unit) 50 shown in FIG. 1. The mobile terminal 50 has the same specifications as the mobile terminal 40 and includes a display unit 51 corresponding to the display unit 41. The above-described driving information display application is installed in the mobile terminal 50.

[0049] (Operations and effects) Next, the operations and effects of the present embodiment will be described.

[0050] First, the flow of processing performed by the CPU 21A of the vehicle 20 will be described using the flowchart of FIG. 8. The CPU 21A repeatedly executes the processing of the flowchart of FIG. 8 every time a predetermined time elapses. In the following description, the processing of the flowcharts of FIGS. 8 to 11 is executed by one processor (CPU), but a plurality of processors (CPUs) may execute the processing of the flowcharts of FIGS. 8 to 11.

[0051] First, in step S10, the CPU 21A determines whether the sleep level of the driver Dr is equal to or higher than a predetermined level. When it is determined to be Yes, the CPU 21A proceeds to step S11 and generates drowsiness detection information. The drowsiness detection information is danger information.

[0052] Subsequently, the CPU 21A proceeds to step S12 and determines whether the PCS has been activated. When it is determined to be Yes, the CPU 21A proceeds to step S13 and generates PCS activation information. The PCS activation information is danger information.

[0053] Subsequently, the CPU 21A proceeds to step S14 and records the vehicle-related information in the storage 21D.

[0054] Subsequently, the CPU 21A proceeds to step S15 and controls the wireless communication I / F 21E to transmit the vehicle-related information recorded in the storage 21D in step S14 to the external server 30.

[0055] When it is determined as No in steps S10 and S12 or when the process of step S15 is completed, the CPU 21A temporarily ends the process of the flowchart in FIG. 8.

[0056] Next, the flow of the process performed by the CPU 31A of the external server 30 will be described using the flowchart in FIG. 9. The CPU 31A repeatedly executes the process of the flowchart in FIG. 9 every time a predetermined time elapses.

[0057] First, in step S20, the CPU 31A determines whether a special condition is satisfied. When it is determined as Yes, the CPU 31A proceeds to step S21 and prohibits the use mode from becoming the privacy mode.

[0058] When the process of step S21 is completed or when it is determined as No in step S20, the CPU 31A proceeds to step S22 and determines whether vehicle-related information has been received from the vehicle 20.

[0059] When it is determined as Yes in step S22, the CPU 31A proceeds to step S23 and records the vehicle-related information in the storage 31D.

[0060] When the process of step S23 is completed or when it is determined as No in step S22, the CPU 31A proceeds to step S24 and determines whether the use mode is the privacy mode.

[0061] When it is determined as Yes in step S24, the CPU 31A proceeds to step S25 and controls the wireless communication I / F 31E to transmit only the general information included in the vehicle-related information recorded in the storage 31D to the mobile terminal 40 while referring to the first list 33.

[0062] When it is determined as No in step S24, the CPU 31A proceeds to step S26 and controls the wireless communication I / F 31E to transmit all the vehicle-related information recorded in the storage 31D to the mobile terminal 40.

[0063] When the processing in step S25 or S26 is completed, the CPU 31A temporarily ends the processing of the flowchart in FIG. 9.

[0064] Next, the flow of processing performed by the CPU 31A of the external server 30 will be described using the flowchart in FIG. 10. The CPU 31A repeatedly executes the processing of the flowchart in FIG. 10 every time a predetermined time elapses.

[0065] The processing in steps S30, S31, and S32 is the same as the processing in steps S20, S21, and S22 described above, respectively.

[0066] When it is determined as Yes in step S32, the CPU 31A proceeds to step S33 and executes a driving diagnosis.

[0067] Subsequently, the CPU 31A proceeds to step S34 and determines whether the driving diagnosis process has been completed.

[0068] When it is determined as Yes in step S34, the CPU 31A proceeds to step S35 and records the driving diagnosis result in the storage 31D.

[0069] When the processing in step S35 is completed or when it is determined as No in step S32, the CPU 31A proceeds to step S36 and determines whether the usage mode is the privacy mode.

[0070] When it is determined as Yes in step S36, the CPU 31A proceeds to step S37 and controls the wireless communication I / F 31E to transmit only the general information included in the operation diagnosis items recorded in the storage 31D to the mobile terminal 40 while referring to the second list 35.

[0071] When it is determined as No in step S36, the CPU 31A proceeds to step S38 and controls the wireless communication I / F 31E to transmit all the operation diagnosis items recorded in the storage 31D to the mobile terminal 40.

[0072] When the processing of step S37 or S38 is completed, the CPU 31A temporarily ends the processing of the flowchart in FIG. 10.

[0073] Next, the flow of processing performed by the CPU of the mobile terminal 40 will be described with reference to the flowchart in FIG. 11. The CPU repeatedly executes the processing of the flowchart in FIG. 11 every time a predetermined time elapses.

[0074] First, in step S40, the CPU determines whether the operation information display application is running.

[0075] When it is determined as Yes in step S40, the CPU proceeds to step S41 and determines whether it has received vehicle-related information or an operation diagnosis result from the external server 30.

[0076] When it is determined as Yes in step S41, the CPU proceeds to step S42. When the mobile terminal 40 receives vehicle-related information in step S41, in step S42, the CPU causes the display unit 41 to display the vehicle-related information.

[0077] For example, when the usage mode is set to the privacy mode, only the general information among the vehicle-related information of the vehicle 20 is displayed on the display unit 41 of the mobile terminal 40. Therefore, in this case, the position information of the vehicle 20 is not displayed on the display unit 41.

[0078] Also, for example, when the external server 30 receives the drowsiness detection information from the vehicle 20, the CPU 31A executes the processes of step S21 and step S26 in FIG. 9. In this case, in step S42, information indicating that the driver Dr is in a drowsy state and the position information of the vehicle 20 are displayed on the display unit 41. Therefore, the family member Fm can recognize that the driver Dr is in a drowsy state and the current position of the vehicle 20 by looking at the display unit 41 of the mobile terminal 40. Therefore, the family member Fm can contact the mobile terminal 50 held by the driver Dr using, for example, the mobile terminal 40.

[0079] Also, for example, when the usage mode is not set to the privacy mode, all vehicle-related information of the vehicle 20 is displayed on the display unit 41 of the mobile terminal 40. Therefore, in this case, the position information of the vehicle 20 and the map data including the position information are displayed on the display unit 41. Therefore, the family member Fm can recognize the driving route and the current position of the vehicle 20 by looking at the display unit 41.

[0080] Also, when the mobile terminal 40 receives the driving diagnosis result in step S41, in step S42, the CPU causes the display unit 41 to display the driving diagnosis result.

[0081] For example, when the usage mode is set to the privacy mode, only the general information in the driving diagnosis result is displayed on the display unit 41. Therefore, even when the vehicle speed of the vehicle 20 exceeds the speed limit, information indicating that the vehicle speed of the vehicle 20 has exceeded the speed limit is not displayed on the display unit 41.

[0082] Also, for example, when the external server 30 receives the drowsiness detection information from the vehicle 20, the CPU 31A executes the processes of step S31 and step S38 in FIG. 10. Here, assume that the vehicle speed of the vehicle 20 exceeds the speed limit. In this case, at step S42, information indicating that the driver Dr is in a drowsy state and information indicating that the vehicle speed of the vehicle 20 has exceeded the speed limit are displayed on the display unit 41. Therefore, by looking at the display unit 41, the family member Fm can recognize that the driver Dr was in a drowsy state and that the vehicle speed of the vehicle 20 exceeded the speed limit.

[0083] Also, for example, when the usage mode is not set to the privacy mode, all the driving diagnosis results of the vehicle 20 are displayed on the display unit 41. Therefore, by looking at the display unit 41, the family member Fm can recognize all the driving diagnosis results.

[0084] When the process of step S42 is completed, or when a No determination is made in step S40 or S41, the CPU 31A temporarily ends the process of the flowchart in FIG. 11.

[0085] As described above, in the present embodiment, general information is transmitted from the external server 30 to the mobile terminal 40. On the other hand, when the privacy mode is set, specific information is not transmitted from the external server 30 to the mobile terminal 40. Therefore, by setting information that the driver Dr does not want the family member Fm to know as specific information, the system 10 can transmit vehicle information (vehicle-related information, driving diagnosis results) regarding the vehicle 20 to the mobile terminal 40 while suppressing giving discomfort to the driver Dr.

[0086] Furthermore, when the privacy mode is set and the external server 30 receives danger information indicating that the driver Dr is in a dangerous situation, the privacy mode is released. Therefore, in this case, the family member Fm can recognize the vehicle information of the vehicle 20 by using the mobile terminal 40.

[0087] Furthermore, when the vehicle 20 is traveling in a predetermined dangerous area (first area), it is prohibited to set the privacy mode. Therefore, the family member Fm can recognize the vehicle information of the vehicle 20 traveling in the dangerous area by using the mobile terminal 40.

[0088] Furthermore, when the privacy mode is set, the restriction is applied only to the information received from the external server 30 by the mobile terminal 40, and this restriction is not applied to the mobile terminal 50. Therefore, for example, after getting off the vehicle 20, the driver Dr can recognize all the diagnosis items of the driving diagnosis result and all the vehicle-related information received from the external server 30 by looking at the display unit 51 of the mobile terminal 50 in which the driving information display application is running.

[0089] As described above, the driver monitoring device, the driver monitoring system, the driver monitoring method, and the program according to the embodiment have been described. However, the driver monitoring device, the driver monitoring system, the driver monitoring method, and the program can be appropriately designed and changed without departing from the gist of the present invention.

[0090] For example, at least one of the mobile terminal (specific information determination unit) 40 and the mobile terminal (specific information determination unit) 50 may have a function of setting an operation mode. Further, the driver Dr may change the contents of the first list 33 and the second list 35 by operating the display unit 51 (touch panel) of the mobile terminal 50. For example, the vehicle speed information in the first list 33 may be set as specific information, or the driving diagnosis item related to the brake operation in the second list 35 may be set as specific information.

[0091] Also, the specific information may include a plurality of specific information with different degrees of freedom of viewing by the family member Fm. For example, assume a case where the specific information includes first specific information and second specific information. The degree of freedom of viewing the first specific information is lower than the degree of freedom of viewing the second specific information. In this case, for example, when the above special condition is satisfied, the external server 30 may transmit the second specific information to the mobile terminal 40, and even when the above special condition is satisfied, the external server 30 may not transmit the first specific information to the mobile terminal 40.

[0092] For example, the system 10 may be configured so that the use mode cannot be set, and the external server 30 may restrict the information transmitted to the mobile terminal 40 according to a predetermined rule. That is, in this modification, the vehicle 20 does not enter the privacy mode. For example, the external server 30 may not transmit the specific information defined in the first list 33 and the second list 35 to the mobile terminal 40, and may transmit only general information to the mobile terminal 40. Note that also in this case, when special conditions are satisfied, the external server 30 may transmit the specific information to the mobile terminal 40. Further, in this case, the system 10 may be configured such that information regarding a dangerous area included in the map data is displayed on the display unit 41 of the mobile terminal 40.

[0093] The terminal device used by the family Fm may be a personal computer and a display connected to the personal computer.
