[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] [Embodiment] 1 is a block diagram showing a schematic configuration example of a driving support system including a driving support device according to an embodiment. The driving system including the driving support device according to the present embodiment shown in FIG. 1 includes a vehicle 1, a terminal device 100, and a server 200.

[0011] The vehicle 1 is a vehicle driven by a driver, and is equipped with a driving assistance function that assists the driver in driving. The terminal device 100 is a personal terminal device used by the driver, or an administrator terminal used by an administrator who manages the operation of the vehicle 1. The server 200 collectively stores data of each terminal device 100. The vehicle 1, the terminal device 100, and the server 200 each have a communication function, and are configured to be able to communicate with each other through a network NW. This network NW is composed of, for example, an Internet line network, a mobile phone line network, etc.

[0012] Fig. 2 is a block diagram showing an example of a schematic configuration of the vehicle shown in Fig. 1. As shown in Fig. 2, the vehicle 1 includes an input unit 2, an output unit 3, a communication unit 4, a control unit 5 as a driving support device, and a storage unit 7.

[0013] The input unit 2 includes a camera 21, a heart rate measuring device 22, a microphone 23, and a switch 24.

[0014] The camera 21 generates image data capturing an image of the driver of the vehicle 1. The camera 21 includes, for example, a complementary metal oxide semiconductor (CMOS) image sensor. The camera 21 may be another type of image sensor, such as a charge-coupled device (CCD) image sensor.

[0015] The heart rate measuring device 22 measures the heart rate of the driver of the vehicle 1. The heart rate measuring device 22 may be mounted on the steering wheel, or may be a wearable device such as a smart watch that can be worn by the driver. The pulse wave measurement may be a non-contact measurement using the Doppler effect using radio waves, a measurement that detects the pulse from the color of the face, or a measurement that measures the pressure generated by the pulse using a piezoelectric element. The heart rate measuring device 22 may also have a function of measuring the breathing of the driver of the vehicle 1 using the Doppler effect using radio waves.

[0016] The microphone 23 captures the voice of the driver of the vehicle 1 and generates voice data.

[0017] The switch 24 has, for example, a push button, and outputs a predetermined signal when the driver presses the push button.

[0018] The output section 3 includes a speaker 31 and an actuator 32 .

[0019] The speaker 31 outputs various sounds under the control of the control unit 5 .

[0020] The actuator 32 outputs various operations under the control of the control unit 5. The actuator 32 generates vibrations in, for example, a seat or a steering wheel.

[0021] The communication unit 4 is wirelessly connected to the network NW and transmits and receives information, signals, etc. to and from various terminals connected to the network NW by wire or wirelessly. The communication unit 4 is provided outside the vehicle 1 and acquires health checkup information from an external device such as a terminal device 100 or a server 200 connected to the network NW.

[0022] The control unit 5 includes an electronic circuit mainly made up of a known microcomputer including a central processing unit such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), a ROM (Read Only Memory), a RAM (Random Access Memory), and an interface. The control unit 5 includes a face detection unit 511, a facial expression detection unit 512, a body part detection unit 521, a motion analysis unit 522, a heart rate detection unit 53, a respiration detection unit 54, a voice detection unit 55, a response detection unit 56, a driver assistance control unit 57, a first sign detection unit 58, a second sign detection unit 59, an abnormal state detection unit 60, an abnormality determination unit 61, and a vehicle control unit 62.

[0023] The face detection unit 511 performs face detection in the image data captured by the camera 21 .

[0024] The facial expression detection unit 512 extracts the facial feature points detected by the face detection unit 511, and detects various facial expressions of the driver of the vehicle 1. Specifically, the facial expression detection unit 512 detects facial expressions such as repeatedly opening and closing the mouth widely, keeping the mouth half-open or wide open, repeatedly looking down intermittently, coughing violently, coughing frequently, keeping the eyes rolled back or closed, paleness, a distorted face (a facial expression of enduring pain), a painful expression, and the like.

[0025] The body part detection unit 521 detects the joints and bones of the human driver, and detects various body parts.

[0026] The motion analysis unit 522 analyzes various motions of the driver of the vehicle 1 based on the motions of the body parts detected by the body part detection unit 521. Specifically, the motion analysis unit 522 detects motions such as touching the head due to discomfort, driving with one hand for a long time, placing a hand firmly on the chest, touching the chest with both hands in a groping manner, rubbing the stomach, loosening the necktie or shirt collar, breathing with the shoulders, pushing out the chest, repeatedly shifting in a sitting position, staggering, poor posture (leaning face down, leaning back, falling to the side, etc.), convulsions, etc.

[0027] The heartbeat detection unit 53 detects the heartbeat of the driver of the vehicle 1 based on the measurement result of the heartbeat measuring device 22. Specifically, the heartbeat detection unit 53 detects a sudden increase or decrease in the heartbeat, arrhythmia, tachycardia, a decrease in blood pressure, and the like based on the measurement result of the heartbeat measuring device 22.

[0028] When the heart rate measuring device 22 has a function of measuring respiration, the respiration detection unit 54 detects the respiration of the driver of the vehicle 1 based on the measurement result. Specifically, the respiration detection unit 54 detects irregular breathing, etc. based on the measurement result of the heart rate measuring device 22.

[0029] The voice detection unit 55 detects the voice of the driver of the vehicle 1 from the voice data generated by the heartbeat detection unit 53. Specifically, the voice detection unit 55 detects the driver's screaming, groaning, slurred speech, loud breathing, and the like.

[0030] The response detection unit 56 detects the response of the driver to the call to the driver. The driver's response may be a voice response or a response by pressing the switch 24.

[0031] The driver assistance control unit 57 changes control related to driving assistance of the vehicle 1 in accordance with medical examination information including the results of a medical examination performed by a doctor on the driver of the vehicle 1. The driver assistance control unit 57 automatically starts the driving assistance function of the vehicle 1 in accordance with the medical examination information. The driver assistance control unit 57 changes parameters used for the driving assistance function of the vehicle 1 in accordance with the medical examination information.

[0032] The first sign detection unit 58 and the second sign detection unit 59 detect, based on information about the driver of the vehicle 1 acquired by the input unit 2, a sign state that indicates a sign that the driver will become unable to drive.

[0033] The first sign detection unit 58 detects a first sign state in which the driver may be unable to drive. For example, when the first sign detection unit 58 detects an unconscious behavior of the driver in response to a physical discomfort of the driver, the first sign detection unit 58 determines that the first sign state exists.

[0034] The second sign detection unit 59 detects a second sign state in which the possibility that the driver will become unable to drive is higher than the first sign state. When the second sign detection unit 59 detects a driver behavior of dealing with or alleviating the driver's physical abnormality, it determines that the second sign state exists.

[0035] The abnormal state detection unit 60 detects an abnormal state indicating that the driver is unable to drive, based on information about the driver of the vehicle 1. When the abnormal state detection unit 60 detects that the driver is unable to drive, it determines that an abnormal state exists. When the abnormal state detection unit 60 detects an abnormal state, it calls out to the driver, and when the driver does not respond to the call within a predetermined period of time, it performs control to avoid a vehicle accident. The call may be a voice call from the speaker 31, or a notification by vibration from the actuator 32. Furthermore, the driver may respond by voice and the response may be detected by the microphone 23, or the driver may respond by pressing the switch 24.

[0036] The first sign detection unit 58, the second sign detection unit 59, and the abnormal condition detection unit 60 detect a first sign condition, a second sign condition, and an abnormal condition, respectively, by different sets of condition detection operations.

[0037] When a predetermined input is received from the communication unit 4, the abnormality determination unit 61 determines that an abnormality has occurred and performs control to avoid a vehicle accident. When an external operator determines that the driver is unable to drive based on information from the camera 21 and microphone 23, he or she transmits a predetermined signal to the vehicle 1.

[0038] The vehicle control unit 62 controls the driving of the vehicle 1. The vehicle control unit 62 may be provided as an ECU separate from the control unit 5. The vehicle control unit 62 performs different controls on the vehicle 1 in the first predictive state, the second predictive state, and the abnormal state. Specifically, the vehicle control unit 62 shortens the time threshold for starting the driving support function for decelerating or stopping the vehicle 1 in the first predictive state. In addition, the vehicle control unit 62 further shortens the time threshold for starting the driving support function for decelerating or stopping the vehicle 1 in the second predictive state compared to the first predictive state. In addition, the vehicle control unit 62 calls out to the driver in the second predictive state and requests the driver to respond. In addition, the vehicle control unit 62 may perform preliminary control for safely stopping the vehicle 1, such as limiting or reducing the speed of the vehicle 1 and maintaining the driving lane, in the second predictive state. In addition, the vehicle control unit 62 further shortens the time threshold for starting the driving support function for decelerating or stopping the vehicle 1 in the abnormal state compared to the second predictive state. Furthermore, the vehicle control unit 62 shortens the time threshold for waiting for a response in an abnormal state. Furthermore, when the abnormality determination unit 61 determines that there is an abnormality, the vehicle control unit 62 performs control to avoid an accident involving the vehicle 1, such as slowing down and stopping the vehicle 1.

[0039] The storage unit 7 may be, for example, a relatively large-capacity storage device such as a hard disk, a solid state drive (SSD), or an optical disk, or a semiconductor memory in which data can be rewritten such as a RAM, a flash memory, or a non-volatile static random access memory (NVSRAM). The storage unit 7 stores conditions and information necessary for various processes in the control unit 5, various programs and applications executed by the control unit 5, control data, and the like. The storage unit 7 also stores personal data 71, detection result data 72, and driving data 73.

[0040] The personal data 71 is information about the individual driver of the vehicle 1, such as name, sex, age, weight, blood pressure, driving history, medical history, etc. The personal data 71 may be the same data as the personal data 2021, which is acquired by the communication unit 4 from the server 200 via the network NW and stored in the memory unit 7.

[0041] The detection result data 72 is information regarding the detection results by the input unit 2 and the control unit 5, and is information such as image data generated by the camera 21, the heart rate measured by the heart rate measuring device 22, audio data generated by the microphone 23, and the detection results in the first precursor detection unit 58, the second precursor detection unit 59, and the abnormal condition detection unit 60.

[0042] The driving data 73 is information related to the driving of the vehicle 1, such as the history of the driver's operation of the vehicle 1, the history of the control of the vehicle 1 by the vehicle control unit 62, and the like.

[0043] Returning to FIG. 1, the terminal device 100 includes an input unit 101, a communication unit 102, and a storage unit 103. The input unit 101 acquires measurement information obtained by measuring the driver's biological information such as blood pressure and weight measured by a wearable device 300 such as a smart watch or a home medical device 400 such as a blood pressure monitor or a weight scale, and stores the information as measurement data 1031 in the storage unit 103. The input unit 101 also accepts input of regular health checkups and other diagnostic and medical examination results by a doctor, and stores the results as medical checkup data 1033 in the storage unit 103. The input unit 101 also acquires roll call information such as check items and working conditions acquired in roll calls performed before, during, and after work from the operation management system 500, and stores the roll call information as roll call data 1032 in the storage unit 103.

[0044] The server 200 includes a communication unit 201 and a storage unit 202. The communication unit 201 acquires the measurement data 1031, the roll call data 1032, and the medical checkup data 1033 via the network NW, and stores them in the storage unit 202 as personal data 2021. In other words, the personal data 2021 includes the measurement data 1031, the roll call data 1032, and the medical checkup data 1033.

[0045] Next, a driving support method by the control unit 5 will be described. Fig. 3 is a flowchart showing an example of processing in the driving support method. First, as shown in Fig. 3, the communication unit 4 acquires personal data 2021 from the server 200 via the network NW (step S1), and stores it in the storage unit 7 as personal data 71. The personal data 71 includes measurement data 1031, roll call data 1032, and medical examination data 1033.

[0046] Next, the control unit 5 judges whether or not there is an abnormality in the medical checkup data 1033 included in the personal data 71 (step S2). For example, when the result of the regular medical checkup shows a problem, the control unit 5 judges that there is an abnormality in the medical checkup data 1033.

[0047] When the control unit 5 determines that there is no abnormality in the medical checkup data 1033 (step S2: No), the control unit 5 determines whether there is an abnormality in the measurement data 1031 and the roll call data 1032 included in the personal data 71 (step S3). For example, when the blood pressure, etc. included in the measurement data 1031 and the roll call data 1032 is equal to or higher than a threshold, the control unit 5 determines that there is an abnormality.

[0048] When the control unit 5 determines that there is no abnormality in the measurement data 1031 and the roll call data 1032 (step S3: No), it executes an abnormality detection process during driving (step S4). The abnormality detection process during driving will be described later.

[0049] Thereafter, the control unit 5 stores data such as the history of the driver's operations on the vehicle 1 while driving, and the history of the control of the vehicle 1 by the vehicle control unit 62 while driving, in the storage unit 7 as driving data 73 (step S5).

[0050] Then, the control unit 5 judges whether or not a predetermined control signal indicating the end of the series of processes is detected (step S6). If the control unit 5 judges that a predetermined control signal indicating the end of the series of processes is detected (step S6: Yes), the series of processes is ended.

[0051] On the other hand, if the control unit 5 determines that the predetermined control signal indicating the end of the process has not been detected (step S6: No), the process returns to step S1 and continues the process.

[0052] In step S2, when the control unit 5 determines that there is an abnormality in the medical examination data 1033 (step S2: Yes), the driver assistance control unit 57 changes the control related to the driving assistance of the vehicle 1. Specifically, the driver assistance control unit 57 adjusts a threshold value used for the driving assistance function of the vehicle 1, or automatically starts the driving assistance function of the vehicle 1 (step S7). For example, in the abnormality detection process during driving described below, when a first predictive state is detected, the driver assistance control unit 57 shortens a time threshold value at which the vehicle control unit 62 starts the driving assistance function of decelerating or stopping the vehicle 1. In addition, the driver assistance control unit 57 may automatically start, for example, the driving assistance function of the vehicle control unit 62 decelerating or stopping the vehicle 1.

[0053] In step S3, if the control unit 5 determines that there is an abnormality in the measurement data 1031 and the roll call data 1032 (step S3: Yes), the driver assistance control unit 57 shortens the time threshold for waiting for a response to the buzzer sound from the speaker 31, for example, when a second premonitory state is detected in the abnormality detection process during driving described below.

[0054] Next, the abnormality detection process during driving will be described. FIG. 4 is a flowchart showing an example of the abnormality detection process during driving. First, as shown in FIG. 4, the first sign detection unit 58 judges whether or not the vehicle is in the first abnormality state (step S11). For example, when the first sign detection unit 58 detects a group of state detection actions such as the driver of the vehicle 1 touching his / her face, chest or shoulders, opening his / her mouth, opening and closing his / her mouth, or coughing frequently as an unconscious behavior of the driver in response to a physical discomfort of the driver in the image data captured by the camera 21, the first sign detection unit 58 judges that the vehicle is in the first abnormality state. In addition, the first sign detection unit 58 may judge that the vehicle is in the first abnormality state when the heart rate of the driver of the vehicle 1 is rapidly increasing or decreasing as measured by the heart rate measuring device 22.

[0055] When the first sign detection unit 58 determines that the vehicle is not in the first sign state (step S11: No), the second sign detection unit 59 determines whether the vehicle is in the second sign state (step S12). For example, when the second sign detection unit 59 detects a group of state detection actions such as the driver of the vehicle 1 firmly placing his / her hands on his / her chest, having a pained expression, or a change (worsening) in facial color as driver behavior to deal with or alleviate the driver's physical abnormality in the image data of the driver captured by the camera 21, the second sign detection unit 59 determines that the vehicle is in the second sign state when the driver is groaning in the voice data of the driver acquired by the microphone 23. The second sign detection unit 59 may also determine that the vehicle is in the second sign state when the heart rate measuring device 22 detects that the driver has an irregular heartbeat, tachycardia, or irregular breathing.

[0056] When the second sign detection unit 59 determines that the vehicle is not in the second sign state (step S12: No), the abnormal state detection unit 60 determines whether the vehicle is in an abnormal state (step S13). For example, when the abnormal state detection unit 60 detects a group of state detection actions such as the driver of the vehicle 1 having closed eyes, white eyes, convulsing, or poor posture in the image data of the driver captured by the camera 21 as a state indicating that the driver is unable to drive, the abnormal state detection unit 60 determines that the vehicle is in an abnormal state. In addition, the abnormal state detection unit 60 may determine that the vehicle is in an abnormal state when the driver of the vehicle 1 is not operating the steering wheel based on the driving data 73. In addition, the abnormal state detection unit 60 may determine that the vehicle is in an abnormal state when the blood pressure of the driver of the vehicle 1 is reduced by the heart rate measuring device 22.

[0057] If the abnormal state detection unit 60 determines that there is no abnormal state (step S13: No), the control unit 5 determines whether or not a predetermined control signal indicating the end of operation has been detected (step S14). If the control unit 5 determines that a predetermined control signal indicating the end of operation has been detected (step S14: Yes), the series of processes ends.

[0058] On the other hand, when the control unit 5 determines that the predetermined control signal indicating the end of operation has not been detected (step S14: No), the process returns to step S11 and continues the process.

[0059] In step S11, when the first sign detection unit 58 determines that the vehicle is in the first sign state (step S11: Yes), the control unit 5 adjusts various thresholds used by the vehicle control unit 62 to control the vehicle 1 (step S15). For example, the control unit 5 shortens the time threshold at which the vehicle control unit 62 starts a driving assistance function to decelerate or stop the vehicle 1.

[0060] In step S12, when the second sign detection unit 59 determines that the vehicle 1 is in the second sign state (step S12: Yes), the control unit 5 adjusts various thresholds used by the vehicle control unit 62 to control the vehicle 1 and starts calling the driver of the vehicle 1 (step S16). For example, the control unit 5 further shortens the time threshold at which the vehicle control unit 62 starts a driving assistance function to decelerate or stop the vehicle 1, compared to the first sign state. In addition, the control unit 5 calls the driver by voice, such as a buzzer sound from the speaker 31, and requests a voice response from the driver. In addition, the control unit 5 may notify an external operator via the communication unit 4 that the second sign state has been detected. This makes it possible to notify the external operator earlier than notifying the operator after detecting the abnormal state. In addition, the control unit 5 may perform preliminary control for safely stopping the vehicle 1, such as limiting or reducing the speed of the vehicle 1 and maintaining the driving lane, at this stage.

[0061] Next, the control unit 5 determines whether or not there is a response from the driver (step S17). For example, when the control unit 5 detects a predetermined response from the driver by the microphone 23, it determines that there is a response from the driver.

[0062] When the control unit 5 determines that there is a response from the driver (step S17: Yes), the process proceeds to step S13 and continues. At this time, the control unit 5 resets various thresholds used by the vehicle control unit 62 to control the vehicle 1 to their initial values.

[0063] On the other hand, if the control unit 5 determines that there is no response from the driver (step S17: No), the control unit 5 causes the vehicle control unit 62 to execute a process of safely decelerating and stopping the vehicle 1 (step S18). The control unit 5 outputs a sound from the speaker 31 to notify the outside of the vehicle of an abnormality, blinks the emergency flasher indicator light to decelerate the vehicle, stops the vehicle 1 on a safe roadside or the like, and ends the process.

[0064] In step S13, when the abnormal state detection unit 60 determines that an abnormal state exists (step S13: Yes), the control unit 5 adjusts various thresholds used by the vehicle control unit 62 to control the vehicle 1, and increases the volume of a buzzer sound that calls the driver of the vehicle 1 (step S19). For example, the control unit 5 further shortens the time threshold at which the vehicle control unit 62 starts a driving assistance function that decelerates or stops the vehicle 1, compared to the second predictive state. Also, the control unit 5 increases the volume of the buzzer sound from the speaker 31, and shortens the time threshold for waiting for a response. Also, the control unit 5 may notify an external operator via the communication unit 4 that an abnormal state has been detected.

[0065] Next, the control unit 5 determines whether or not there is a response from the driver (step S20). If the control unit 5 determines that there is a response from the driver (step S20: Yes), the control unit 5 proceeds to step S14 and continues the process. At this time, the control unit 5 resets various thresholds used by the vehicle control unit 62 to control the vehicle 1 to their initial values.

[0066] On the other hand, if the control unit 5 determines that there is no response from the driver (step S20: No), the process proceeds to step S18 and continues.

[0067] According to the driving assistance device described above, the control unit 5 changes the control related to the driving assistance of the vehicle 1 in accordance with the health check information, so that driving can be supported in consideration of the health condition of the driver. For example, if the health check reveals a problem, the driver assistance control unit 57 can improve safety by shortening in advance the time threshold at which the vehicle control unit 62 starts the driving assistance function of decelerating or stopping the vehicle 1 when a first predictive state is detected.

[0068] Furthermore, according to the driving assistance device, the control unit 5 automatically starts the driving assistance function of the vehicle 1 in response to the medical examination information, so that driving can be assisted in consideration of the driver's health condition. For example, if the medical examination reveals any abnormalities, the driver assistance control unit 57 can improve safety by having the vehicle control unit 62 automatically start the driving assistance function to slow down or stop the vehicle 1.

[0069] In addition, according to the driving assistance device, the communication unit 4 acquires the health check information from an external device connected to the network NW, so that the effort of inputting the health check information when starting to drive the vehicle 1 can be eliminated.

[0070] Furthermore, according to the driving assistance device, the control unit 5 changes parameters used for the driving assistance function of the vehicle 1 in accordance with the health check information, so that driving can be assisted in consideration of the driver's health condition.

[0071] Furthermore, according to the driving assistance device, the control unit 5 changes control relating to driving assistance for the vehicle 1 in response to the measurement information, so that driving can be accurately assisted in consideration of daily changes in the driver's physical condition.

[0072] Furthermore, according to the driving assistance device, the control unit 5 changes the control related to the driving assistance of the vehicle 1 in response to the roll call information, so that driving can be accurately assisted in consideration of the situation at the time of the driver's roll call.

[0073] The driving assistance device according to the embodiment of the present invention described above is not limited to the above-described embodiment, and various modifications are possible within the scope of the claims.

[0074] In the above description, an example has been described in which the vehicle 1 is equipped with the control unit 5 that is a driving assistance device, but a terminal outside the vehicle 1 may have the function of the driving assistance device.

[0075] The driving assistance device according to this embodiment may be configured by appropriately combining the components of the embodiment and modified examples described above. [Explanation of symbols]
