<First Embodiment>
[Configuration of Vehicle Control Device 1]
FIG. 1 is a diagram illustrating a configuration of a vehicle S having a vehicle control device 1. The vehicle S includes a vehicle control device 1, an imaging unit 2, a driving operation unit 3, a reception unit 4, an engine 5, and a communication unit 6. The vehicle control device 1 is a device for ensuring safety by stopping the vehicle S when the driving state by the driver of the vehicle S shows an abnormal pattern peculiar to the driver in advance. Details of the vehicle control device 1 will be described later.

  The imaging unit 2 is a camera having a lens for imaging a driver of the vehicle S and an imaging element. The imaging unit 2 includes a plurality of cameras provided at the lower part of the instrument panel and the handle, etc., and the movement of the driver's hand, the movement of the driver's feet, the movement of the driver's head, A captured image used for grasping the state of the driver, such as the movement of the upper body of the vehicle and the movement of the eyeball of the driver, is generated. The imaging unit 2 notifies the generated captured image to the vehicle control device 1.

  The driving operation unit 3 includes devices for driving the vehicle S, such as a steering wheel, an accelerator pedal, and a brake pedal. Further, the driving operation unit 3 includes an angle sensor that detects the operation amount of the steering wheel, and a sensor that detects the operation amounts of the accelerator pedal and the brake pedal. The driving operation unit 3 notifies the vehicle control device 1 of information indicating the operation amount acquired from these sensors.

The reception unit 4 is a touch panel superimposed on a display in the instrument panel, and receives an operation by a driver or the like.
The engine 5 operates based on control by the vehicle control device 1. The engine 5 stops its operation in response to receiving a stop instruction from the vehicle control device 1.
The communication unit 6 transmits / receives data to / from an external device via a wireless line. For example, based on an instruction from the vehicle control device 1, the communication unit 6 transmits report information indicating that an abnormal state has occurred to a company or a driver's family terminal to which the driver of the vehicle S belongs.

Next, the configuration of the vehicle control device 1 will be described. The vehicle control device 1 includes a storage unit 11 and a control unit 12.
The storage unit 11 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 11 stores a program executed by the control unit 12. Further, the storage unit 11 stores various data used by the control unit 12 to control the operation of the vehicle S. For example, the storage unit 11 stores an operation pattern when the driver performs an abnormal driving in association with the identification information of the driver.

  FIG. 2 is a diagram illustrating an example of an abnormal pattern table stored in the storage unit 11. In the abnormality pattern table, the identification information of the driver, the body state, the steering wheel state, the accelerator state, and the brake state are associated with each other. For example, in the case of a driver who has a history of epileptic seizures, it is known that for each driver, the symptoms when the seizure occurs are constant. Therefore, the vehicle control device 1 operates the driver's body state imaged by the imaging unit 2 when the seizure peculiar to the driver occurs, and the operation of the steering wheel, accelerator pedal, and brake pedal detected by the driving operation unit 3. By comparing the state with the state indicated by the abnormal pattern table, it is possible to detect that a specific seizure has occurred in the driver.

  In the abnormal pattern table shown in FIG. 2, the driver of the identification information 001 operates the steering wheel, the access pedal, and the brake pedal even when the right body becomes stiff when an attack occurs and the operation is indispensable. In other words, it has a characteristic that it does not change (cannot be operated). In addition, the driver of the identification information 002 has a characteristic that the left hand is stiff when a seizure occurs, and the steering wheel is not operated and the steering cannot be performed even in a situation where the operation is indispensable. Show. Further, the driver of the identification information 003 indicates that a seizure occurs when a seizure occurs and the positions of the steering wheel, the access pedal, and the brake pedal vibrate.

  Returning to FIG. 1, the details of the control unit 12 will be described. The control unit 12 is, for example, a CPU (Central Processing Unit), and functions as the specifying unit 121, the abnormal pattern acquisition unit 122, and the travel control unit 123 by executing a program stored in the storage unit 11.

  The identification unit 121 identifies the state of the driver based on the captured image captured by the imaging unit 2 and the operation status of the steering wheel, the accelerator pedal, and the like detected by the driving operation unit 3. The specifying unit 121 specifies the driving state of the vehicle S by the driver based on the specified driver operation state. The specifying unit 121 according to the first embodiment, for example, based on the captured image, the state of the driver's hand, the state of the driver's feet, the state of the driver's head, the state of the driver's upper body, and the driver And the driving state information indicating the specified driving state is notified to the traveling control unit 123.

The abnormal pattern acquisition unit 122 acquires the abnormal pattern of the driver's body associated with the driver of the vehicle S, which is stored in the storage unit 11. The abnormal pattern acquisition unit 122 may acquire an abnormal pattern from an external server.
The abnormal pattern acquisition unit 122 may acquire the driver identification information via the reception unit 4, and may acquire an abnormal pattern associated with the driver based on the acquired identification information. For example, the abnormal pattern acquisition unit 122 displays a screen for inputting identification information on the reception unit 4 and acquires the identification information based on characters or numbers input by the driver. The abnormal pattern acquisition unit 122 may acquire the identification information by wirelessly receiving the identification information stored in the key of the vehicle S, for example.

  The traveling control unit 123 stops the vehicle S when the driving state information acquired from the specifying unit 121 indicates a state corresponding to the abnormal pattern acquired by the abnormal pattern acquisition unit 122. For example, when the driver of the identification information 001 is driving, the driving state information indicates that the right half of the body is stiff and the steering wheel, access pedal, and brake pedal have not changed over a predetermined time. 123 determines that a seizure has occurred in the driver and stops the vehicle S. Even when the driving state information does not indicate a state corresponding to the abnormal pattern, the traveling control unit 123 determines, for example, that the driver is dozing, based on the captured image generated by the imaging unit 2. Stops the vehicle S.

  When symptoms such as epilepsy that may cause a serious accident occur when driving again, it is dangerous for the driver to drive the vehicle S again after the traveling control unit 123 stops the vehicle S. Therefore, the traveling control unit 123 determines whether or not to allow the vehicle S to be restarted after stopping the vehicle S. When the driving state indicates another abnormal state (for example, a dozing state) different from the abnormal pattern, the traveling control unit 123 allows the vehicle S to be restarted without performing a predetermined operation after stopping the vehicle. To do. For example, the travel control unit 123 restarts the travel of the vehicle S by, for example, the restart operation of the driver unless the cause of the stop of the vehicle S is due to the occurrence of an abnormal pattern peculiar to the driver. Allow.

  On the other hand, if the factor that caused the vehicle S to stop is that an abnormal operation pattern specific to the driver has occurred, the traveling control unit 123 may perform an operation of restarting the driver, It is not permitted to resume the traveling of the vehicle S. By dealing in this way, the driver can be prohibited from driving again when a seizure such as epilepsy occurs.

  However, if the vehicle S cannot be moved over a long period of time, it will cause trouble for surrounding vehicles. Therefore, after the vehicle S is stopped, the travel control unit 123 normally restarts the vehicle when the vehicle S is stopped without causing the driving state to indicate a state corresponding to the abnormal pattern. Until the predetermined operation different from the engine start operation is performed, the restart of the vehicle S may be prohibited, and when the predetermined operation is performed, the restart of the vehicle S may be permitted. For example, after the driving control unit 123 stops the vehicle S because the driving state information indicates a state corresponding to the abnormal pattern, an abnormal state occurs in the contact information such as the company to which the driver belongs and the family of the driver. A message for entering the password is displayed on a display (not shown). Then, the traveling control unit 123 permits the vehicle S to be restarted when the password input by the person who has come to the rescue matches a predetermined password.

  In addition to this, the traveling control unit 123 may perform different control based on whether or not the driving state matches the abnormal pattern. For example, when the driving state matches the abnormal pattern, the traveling control unit 123 may stop the vehicle S at an earlier timing than when the driving state indicates another abnormal state different from the abnormal pattern. By doing in this way, when the abnormal pattern which is easy to lead to a serious accident occurs, the traveling control unit 123 has a greater risk due to quickly stopping the vehicle S and suddenly stopping the vehicle S. In the case of an abnormal state that can be considered, it is possible to prevent the vehicle S from stopping unless the abnormal state continues longer than a predetermined time.

  In addition, when the driving state matches the abnormal pattern, the traveling control unit 123 notifies the predetermined contact via the communication unit 6 that the abnormal state has occurred and stops the vehicle S so that the driving state is When another abnormal state different from the abnormal pattern is indicated, the vehicle S is stopped without notifying the contact that the abnormal state has occurred. In this way, when the driver falls into a state where rescue is necessary, such as epilepsy, the driver can be rescued promptly, and the driver himself rests like a dozing drive. If there is a high possibility of recovery (when not sick), it is possible to avoid being notified to the contact information.

[Operation Flowchart of Vehicle Control Device 1]
FIG. 3 is a flowchart showing an operation flow of the vehicle control device 1.
First, the traveling control unit 123 refers to the abnormal pattern table stored in the storage unit 11 and acquires an abnormal pattern corresponding to the driver identification information (S11).

  Subsequently, the traveling control unit 123 acquires information indicating the driving state specified by the specifying unit 121 (S12). The traveling control unit 123 determines whether or not the driving state indicated by the information acquired in S12 matches the abnormal pattern acquired in S11 (S13). When traveling control unit 123 determines that the driving state is not abnormal (NO in S13), it returns the process to S12. When it is determined that the driving state is abnormal (YES in S13), traveling control unit 123 stops vehicle S (S14).

  Thereafter, when the driver tries to restart the vehicle S, the traveling control unit 123 determines whether or not the restart is permitted (S15). If it is determined that the restart may be permitted (YES in S15), traveling control unit 123 restarts vehicle S (S16). On the other hand, when traveling control unit 123 determines that it is a serious abnormal state in which restart cannot be permitted (NO in S15), it notifies the predetermined contact without permitting restart of vehicle S (S17). ).

[Modification]
In the above description, the traveling control unit 123 stops the vehicle S or reports to a predetermined contact when an abnormal state is detected. The driving control unit 123 has the abnormal pattern acquired by the abnormal pattern acquisition unit 122 so that the reported person or the person who has rescued the vehicle S can check the state when the abnormal state occurs. , The image captured by the imaging unit 2 within the predetermined period immediately before is stored in the storage unit 11. And the traveling control part 123 may output the memorize | stored image to a display part (not shown) and another terminal by having received predetermined operation. By doing in this way, the vehicle control apparatus 1 can take appropriate measures after the person who has been informed or the person who has come to the vehicle S for rescue knows the situation when the abnormal state occurs. become.

[Effect in the first embodiment]
As described above, the vehicle control device 1 according to the first embodiment stores the abnormal pattern associated with the identification information of the driver, and the information indicating the driving state indicates the state corresponding to the abnormal pattern. If so, the vehicle S is stopped. By doing so, it becomes possible to prevent a serious accident when a seizure occurs due to a disease such as epilepsy in which symptoms specific to the individual develop.

  Further, the vehicle control device 1 determines whether or not the restart of the vehicle S is permitted after the vehicle S is stopped, and after the vehicle S is stopped until the predetermined operation is performed. S restart is prohibited. On the other hand, when the vehicle S is stopped because the driving state indicates another abnormal state different from the abnormal pattern, the vehicle control device 1 stops the vehicle and does not perform a predetermined operation after the vehicle is stopped. Allow restart. In this way, it is possible to prevent the driver from starting driving again without receiving a doctor's diagnosis after the seizure such as epilepsy has subsided.

  Further, when the driving state matches the abnormal pattern, the vehicle control device 1 stops the vehicle S at an earlier timing than when the driving state indicates another abnormal state different from the abnormal pattern. By doing in this way, the vehicle control device 1 stops the vehicle S promptly in response to the occurrence of the seizure when the possibility that the seizure peculiar to the driver occurs is not zero, and causes a serious abnormality. However, it is possible to prevent the vehicle S from stopping even though it is not.

<Second Embodiment>
In the first embodiment, the case where there is only one abnormal pattern associated with the driver regardless of the environment in which the vehicle S is traveling has been described. However, the state of the road on which the vehicle S is traveling, the weather, etc. The abnormal pattern may vary depending on external factors. Therefore, in the second embodiment, the vehicle control device 1 recognizes the situation around the vehicle S, and an abnormality that can lead to a serious accident such as epilepsy based on the abnormality pattern corresponding to the recognized surrounding situation. It differs from the first embodiment in that it occurs.

  FIG. 4 is a diagram illustrating a configuration of a vehicle S including the vehicle control device 1 according to the second embodiment. The vehicle S shown in FIG. 4 is different from the vehicle S shown in FIG. 1 in that it further includes an ambient condition detection unit 7 and an ambient condition specifying unit 124, and is the same in other respects. FIG. 5 is a table showing the types of external factors. The storage unit 11 stores an abnormal pattern corresponding to the type of external factor.

  The ambient condition detection unit 7 includes a plurality of sensors that detect conditions around the vehicle S. The ambient condition detection unit 7 measures, for example, a sensor that detects temperature and humidity, a sensor that detects brightness, a sensor that detects the slope of a road on which the vehicle S travels, and a distance between the vehicle S and a vehicle traveling ahead. And a sensor for detecting the position of the vehicle S (for example, from a vehicle that captures the location of a vehicle in a wide range, such as a car navigation system, to a level that captures where the vehicle is in the current lane) is there. These sensors output a signal corresponding to the detected surrounding situation as the surrounding situation information.

  The surrounding situation specifying unit 124 specifies the surrounding situation of the vehicle S. Specifically, the surrounding situation specifying unit 124 specifies the surrounding situation based on the result detected by the surrounding situation detection unit 7, and generates the surrounding situation information indicating the specified situation. The surrounding situation specifying unit 124 notifies the traveling control unit 123 of the generated surrounding situation information.

  The traveling control unit 123 stops the vehicle S when the driving state information identified by the identifying unit 121 indicates a state corresponding to an abnormal pattern associated with an external factor corresponding to the surrounding state information. Specifically, the traveling control unit 123 reads out from the storage unit 11 an abnormal pattern corresponding to an external factor corresponding to the ambient condition indicated by the ambient condition information notified from the ambient condition identifying unit 124, and the identifying unit 121 The identified operation state is compared with the read abnormality pattern. And the traveling control part 123 performs the process similar to 1st Embodiment based on the compared result.

[Effects of Second Embodiment]
As described above, the vehicle control device 1 according to the second embodiment acquires an abnormal pattern associated with an external factor, and the driving state information corresponds to an external situation in which the vehicle S is traveling. The vehicle S is stopped when the state corresponding to the abnormal pattern associated with the factor is indicated. By doing in this way, even if it is a case where an abnormal pattern differs for every external factor, the vehicle control apparatus 1 can detect an abnormal state with high precision, and can stop the vehicle S rapidly.

<Third Embodiment>
The specifying unit 121 in the first embodiment and the second embodiment determines the state of the driver based on the captured image captured by the imaging unit 2 and the operation status of the steering wheel, the accelerator pedal, and the like detected by the driving operation unit 3. Identified. On the other hand, the vehicle in the third embodiment is equipped with a measurement unit 8 that measures a driver's pulse wave and brain wave, and the specifying unit 121 applies the pulse wave and brain wave measured by the measurement unit 8. Based on this, it differs from the first embodiment and the second embodiment in that the state of the driver is specified.

  FIG. 6 is a diagram illustrating a configuration of the vehicle S including the vehicle control device 1 according to the third embodiment. As described above, the measuring unit 8 is mounted on the vehicle S, and the measuring unit 8 notifies the specifying unit 121 of the measured pulse wave and brain wave measurement data. The measuring unit 8 includes, for example, a pulse wave sensor unit worn on the driver's wrist and an electroencephalogram sensor unit worn on the driver's head. Although the imaging unit 2 and the driving operation unit 3 are not shown in FIG. 6, the imaging unit 2 and the driving operation unit 3 are mounted on the vehicle S, as in the first and second embodiments. May be. Moreover, the surrounding state detection part 7 may be mounted in the vehicle S similarly to 2nd Embodiment.

  The storage unit 11 stores pulse wave and brain wave data when the driver's state is abnormal in association with the driver's identification information. The pulse wave and brain wave data are, for example, data indicating at least one of the period, amplitude, and waveform of each of the pulse wave and the brain wave. The storage unit 11 is data of a pulse wave and an electroencephalogram within a predetermined time before the time when the driver has an epileptic seizure, measured in a hospital, for example, and is different from a normal state (that is, prodromal symptoms) Is stored as data indicating an abnormal pattern. Such abnormal pattern data is stored in the storage unit 11 via the reception unit 4 and the abnormal pattern acquisition unit 122 using a tool for writing data to the storage unit 11 by an administrator of a company to which the driver belongs, for example. Can write.

  The identification unit 121 identifies the state of the driver's pulse wave and brain wave based on the measurement result of the pulse wave and brain wave measured by the measurement unit 8 while the driver is driving the vehicle S. For example, the specifying unit 121 specifies at least one of the period, amplitude, and waveform of the driver's pulse wave and at least one of the period, amplitude, and waveform of the brain wave, thereby Identify the state.

  The abnormal pattern acquisition unit 122 acquires information indicating the state of the pulse wave and the electroencephalogram specified by the specifying unit 121, and acquires the pulse wave and electroencephalogram data stored in the storage unit 11 as an abnormal pattern. Then, the traveling control unit 123 stops the vehicle S when the state of the pulse wave and brain wave of the driver specified by the specifying unit 121 is similar to the abnormal pattern acquired by the abnormal pattern acquisition unit 122. For example, the traveling control unit 123 calculates a correlation value between the pulse wave and brain wave data of the driver specified by the specifying unit 121 and the abnormal pattern data, and the correlation value is larger than a predetermined value. , It is determined that there is a possibility that the driver may have seizures, resulting in a state of reduced or unconsciousness.

  When it is determined that there is a possibility that the driver may have a seizure, the traveling control unit 123 may perform a preliminary stop operation that sounds a warning sound or prohibits acceleration before stopping the vehicle S. If the abnormalities of the pulse wave and the electroencephalogram are resolved during the stop preliminary operation, the traveling control unit 123 returns to the normal driving state, and the abnormal state of the electroencephalogram and the electroencephalogram is also performed during the preliminary stop operation. The vehicle S may be stopped when the operation continues.

  In addition, the traveling control unit 123 may monitor only the pulse wave during driving, and when the pulse wave is similar to the abnormal pattern, the traveling control unit 123 may perform the preliminary stop operation and start monitoring the brain wave. Then, the traveling control unit 123 stops the vehicle S when it is determined that the brain wave is similar to the abnormal pattern during the stop preliminary operation. In this way, the traveling control unit 123 can determine that an abnormal state has occurred with high accuracy while suppressing the processing amount in the steady state.

  The traveling control unit 123 permits the vehicle S to be restarted when the pulse wave and brain wave data return to a normal state after a predetermined time has elapsed since the vehicle S was stopped. The traveling control unit 123 may permit the restart of the vehicle S on the condition that the driver has performed a predetermined operation. For example, the traveling control unit 123 may use a measuring instrument that measures a pupil state or an operation in which a driver normally holds a ball-shaped sensor, for example, as an operation that is difficult to perform in a state in which a seizure such as epilepsy occurs. When the operation to hit the eyes is normally performed, the restart of the vehicle S is permitted.

  The storage unit 11 stores the operation contents to be performed before restarting in association with the driver identification information in association with the driver identification information, and the traveling control unit 123 corresponds to the driver with the identification information. When the operation to perform is performed normally, restart of the vehicle S may be permitted. By doing in this way, since the driving | running | working control part 123 has a peculiar symptom when a driver | operator had a seizure, it can confirm with high precision whether the driver | operator has not caused the seizure. , Improve safety.

  Note that the measurement unit 8 may notify the travel control unit 123 of mounting information indicating that the driver has detected that the measurement unit 8 is mounted. The traveling control unit 123 permits the traveling of the vehicle S on the condition that the notification of the wearing information is received from the measuring unit 8. By doing in this way, a driver with a disease such as epilepsy can reliably monitor the pulse wave and brain wave while driving.

(Modification)
When the surrounding state detection unit 7 is mounted on the vehicle S, the storage unit 11 may store an abnormal pattern of the driver's pulse wave and brain wave in association with the surrounding state. Then, the traveling control unit 123 resembles the pulse wave and brain wave states of the driver specified by the specifying unit 121 with the abnormal patterns of the pulse wave and brain waves stored in association with the surrounding state detected by the surrounding state detection unit 7. If it is determined that the vehicle S is being operated, the vehicle S may be stopped. By doing in this way, the vehicle control apparatus 1 can improve the precision which detects that a driver | operator is in an abnormal state, when the tendency of a pulse wave or an electroencephalogram changes with temperature or a time slot | zone.

[Effect in the third embodiment]
As described above, the vehicle control apparatus 1 according to the third embodiment detects an abnormal state of the driver based on the pulse wave and the brain wave, so that the driver causes the seizure before the seizure such as epilepsy occurs. Detect that there is a possibility. Therefore, since the vehicle control apparatus 1 can take measures such as stopping the vehicle S before the seizure occurs, safety is improved.

  Moreover, the vehicle control apparatus 1 can improve the precision which estimates that a seizure may occur by using an electroencephalogram with a pulse wave. For example, when only the pulse wave is used, when a person jumps out or is about to collide with a vehicle in front, the pulse may be accelerated, and symptoms similar to prodrome symptoms such as epilepsy may appear. However, since the vehicle control device 1 is also less susceptible to the influence of the surrounding environment by using brain waves, the accuracy is improved.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment.

New embodiments resulting from any combination of these are also included in the embodiments of the present invention. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

  For example, in the above description, epilepsy is exemplified as a disease having an abnormal pattern peculiar to each person, but the type of such disease is not limited thereto. When a driver who has a disease with a specific abnormal pattern is driving, the present invention can be applied even when the driver has a disease other than epilepsy.
