This Embodiment
[Configuration of Vehicle S]
FIG. 1 is a view showing the configuration of a vehicle S having a vehicle control device 1.
The vehicle S includes a vehicle control device 1, an operation unit 2, a position detection unit 3, a seat belt operation unit 4, an internal notification unit 5, an automatic steering unit 6, and an external notification unit 7.

  The vehicle control device 1 is a device that determines whether or not the driver of the vehicle S is in a physical condition change, and controls the vehicle S so as to safely protect the driver of the vehicle S based on the determination result. The operation unit 2 is a device for the driver of the vehicle S to drive the vehicle S. The operation unit 2 is, for example, a steering wheel, an accelerator pedal, or a brake pedal. In addition to the device for driving the vehicle S, the operation unit 2 may include, for example, an operation switch.

  The position detection unit 3 is a device having a function of detecting the position of the vehicle S. The position detection unit 3 includes, for example, a GPS receiver that receives a GPS (Global Positioning System) signal. The position detection unit 3 notifies the control unit 11 of information indicating the detected position.

  The seat belt operating unit 4 has a function of moving the seat belt of the vehicle S. The seat belt operating unit 4 has an actuator (not shown) connected to the seat belt, and moves the position of the seat belt in the longitudinal direction by the actuator. The seat belt operating unit 4 moves the seat belt in a longitudinal direction so as to be wound up or relaxed while the driver is seated on the seat and wearing the seat belt. The seat belt operating unit 4 may move the seat belt only when the driver wears the seat belt. For example, the seat belt operating unit 4 moves the seat belt on condition that a sensor (not shown) for detecting that the seat belt is worn is detecting that the driver is wearing the seat belt. .

  The internal notification unit 5 has a function of notifying the driver of the vehicle S that a physical condition change has occurred. The internal notification unit 5 is, for example, a display in an instrument panel or a speaker provided in the vehicle S. The physical condition change that occurs to the driver includes, for example, seizures, impaired consciousness, or a state in which the consciousness is depressed due to severe pain in the chest or belly.

  The automatic steering unit 6 has a function of automatically steering the vehicle S in a state where the driver of the vehicle S does not steer the vehicle S. The external notification unit 7 has a function of notifying the outside of the vehicle S that the driver's physical condition has changed. The external notification unit 7 is, for example, a hazard lamp or a horn.

Configuration of Vehicle Control Device 1
Next, the configuration of the vehicle control device 1 will be described. The vehicle control device 1 includes a control unit 11 and a storage unit 12. The control unit 11 is, for example, a central processing unit (CPU), and functions as a reaction detection unit 111, a traveling state determination unit 112, and a vehicle control unit 113 by executing a program stored in the storage unit 12. Details of the control unit 11 will be described later.

  The storage unit 12 includes a read only memory (ROM) and a random access memory (RAM). The storage unit 12 stores a program that the control unit 11 executes. The storage unit 12 stores various data used by the control unit 11 to control the driving of the vehicle S.

  The storage unit 12 also stores an abnormal driving pattern of the vehicle S. As an abnormal driving pattern, for example, when it is detected that the vehicle S is traveling around the station in the commuting time zone by GPS, the vehicle S approaches the vehicle ahead of the vehicle S at a turn of a signal or the like, There is a driving pattern in which S leaves the lane early at the junction.

  The reaction detection unit 111 detects a reaction of the driver of the vehicle S. Specifically, the reaction detection unit 111 detects that the driver operates the operation unit 2. The reaction detection unit 111 detects, for example, that the driver has operated the brake pedal. Then, reaction detection unit 111 notifies vehicle control unit 113 of operation information indicating that an operation has been performed by operation unit 2.

  The traveling state determination unit 112 determines whether the traveling state of the vehicle S is abnormal based on the detection result of the position of the vehicle S by the position detection unit 3. The traveling state determination unit 112 compares the position information obtained by the position detection unit 3 and the operation information obtained by the operation unit 2 with the abnormal operation pattern indicating the abnormal operation of the vehicle S stored in the storage unit 12. By doing this, it is determined whether the traveling state of the vehicle S is abnormal. Then, the traveling state determination unit 112 notifies the vehicle control unit 113 of the determination result as to whether or not the traveling state of the vehicle S is abnormal.

  The vehicle control unit 113 has a function of controlling the vehicle S based on the detection result of the reaction detection unit 111 and the determination result of the traveling state determination unit 112. The vehicle control unit 113 acquires the determination result as to whether or not the traveling state of the vehicle S is abnormal from the traveling state determination unit 112, and when the determination result that the traveling state of the vehicle S is abnormal is acquired, the seat The belt operating unit 4 is operated. Then, after activating the seat belt operating unit 4, the vehicle control unit 113 acquires the detection result as to whether or not there is a reaction of the driver of the vehicle S from the reaction detection unit 111, and the reaction of the driver of the vehicle S When the detection result that there is no is acquired, each part of the vehicle S is controlled.

[Operation Flowchart of Vehicle Control Device 1]
FIG. 2 is a flowchart showing the flow of the operation of the vehicle control device 1.
First, the traveling state determination unit 112 detects the traveling state of the vehicle S (S11). Next, the traveling state determination unit 112 determines whether the traveling state of the vehicle S detected in S11 is abnormal (S12). If the traveling state determination unit 112 determines that the traveling state of the vehicle S is abnormal (YES in S12), the vehicle control unit 113 operates the seat belt operating unit 4 (S13).

  Specifically, for example, although the traveling state determination unit 112 detects that the vehicle S is in a city where there are many other vehicles and traveling vehicles expected to be around by GPS, the accelerator pedal of the vehicle S is In some cases, it may be detected that the door is fully opened. In this case, the vehicle control unit 113 operates the seat belt operating unit 4. When the traveling state determination unit 112 determines that the traveling state of the vehicle S is not abnormal in S12 (NO in S12), the process returns to S11.

  Next, the reaction detection unit 111 detects a reaction of the driver of the vehicle S after the seat belt operating unit 4 operates the seat belt (S14). Specifically, the reaction detection unit 111 detects whether or not the driver of the vehicle S operates the operation unit 2 within a predetermined first time after the seat belt operation unit 4 operates the seat belt. Do. The predetermined first time is, for example, a time based on the time when a human can start an action in response to an external instruction, and is, for example, one second. When there is no reaction of the driver of the vehicle S within the predetermined first time (YES in S15), the vehicle control unit 113 operates the internal notification unit 5 (S16).

  Then, the vehicle control unit 113 operates the automatic steering unit 6 (S17). The vehicle control unit 113 operates the automatic steering unit 6 when, for example, the driver does not operate the operation unit 2 within a predetermined second time after the internal notification unit 5 is operated, so that the vehicle S can be Automatic driving can be performed without the need for driving operation by a driver who has lost consciousness.

  In addition, when there is no reaction of the driver in S15 (YES in S15), the vehicle control unit 113 operates the external notification unit 7 to cause an abnormality due to a physical condition change in the driver of the vehicle S outside the vehicle S. May be notified. In this case, specifically, the vehicle control unit 113 may notify the outside of the vehicle S visually or aurally by turning on a hazard lamp or sounding a horn.

  The vehicle S that is automatically steered at S17 travels, for example, at a reduced speed, and stops at a safe place. Then, the door lock of the vehicle S is released to allow the surrounding people to rescue the driver after the vehicle S is stopped.

  In addition, for example, when the vehicle control unit 113 determines that there is no reaction from the driver due to the driver's nap or the like although the driver has a normal awareness (YES in S15), for example, from the display unit When the instruction sound "Please operate the blinker switch left, right, left or right." Or "Please push the horn switch 3 times." Is output, and it is determined that the driver's operation matches the instruction. The automatic steering of the vehicle S may be interrupted.

  If the driver of the vehicle S responds to the operation of the seat belt (NO in S15), the process returns to S11. When there is a reaction of the driver of the vehicle S, the control unit 11 stores in the storage unit 12 that there has been a reaction of the driver each time. Then, when the frequency of operating the seat belt is increasing, the vehicle control unit 113 causes a warning to be displayed on the internal notification unit 5 in the instrument panel or the like, or causes the automatic steering unit 6 to start automatic steering. You may

  For example, when the number of times the seat belt is operated within a predetermined period becomes equal to or more than a predetermined first threshold, the vehicle control unit 113 says, "Please feel free because it seems to be tired." A warning is displayed, and the automatic steering unit 6 starts automatic steering when the number of times of actuation of the seat belt becomes a second threshold larger than the first threshold. By doing this, the vehicle S can ensure that the driver himself / herself is aware of the dangerous state and by starting the automatic driving when the state is not improved, safety can be secured.

[Modification]
In the above embodiment, the vehicle control unit 113 operates the seat belt operating unit 4 to operate the seat belt of the driver of the vehicle S. However, the seat belt operating unit 4 operates the seat belts of other occupants. You may Further, the seat belt operating unit 4 may first operate the driver's seat belt, and may operate the seat belts of other occupants when there is no driver's reaction within a predetermined time. By having such a configuration, the vehicle control device 1 can call attention to other occupants, for example, even when the driver of the vehicle S loses consciousness and can not react.

  In the above embodiment, the vehicle S has the position detection unit 3, and the traveling state determination unit 112 determines whether the traveling state is abnormal based on the position information acquired from the position detection unit 3. However, it is not limited to this. The vehicle S has, for example, a lane departure warning device or a collision prevention device, and the traveling state determination unit 112 determines whether the traveling state is abnormal based on the signals acquired from these devices. May be When the vehicle S has a lane departure warning device, the traveling state determination unit 112 determines that the traveling state is abnormal, for example, when detecting that the vehicle S is out of the lane. When the vehicle S has a collision prevention device, for example, when it is detected that the distance between the vehicle S and the vehicle located in front of the vehicle S is within a predetermined distance, the traveling state is abnormal. judge.

  In the above embodiment, the seat belt operating unit 4 operates the seat belt. However, the seat belt operating unit 4 strengthens the driving of the seat belt in a stepwise manner. The reaction may be determined. In this case, at first, the seat belt operating unit 4 operates the seat belt in a small size, and the reaction detection unit 111 detects a reaction of the driver. Then, when the driver's reaction is not detected, the seat belt operating unit 4 operates the seat belt more largely, and the reaction detection unit 111 detects the driver's reaction. This can prevent the seat belt from moving suddenly and the driver being surprised.

[Effects of the vehicle control device 1 according to the present embodiment]

And a vehicle control unit 113 that controls the vehicle S based on the result of the reaction detection unit 111.

  In the vehicle control device 1 according to the present embodiment, the reaction detection unit 111 detects the reaction of the driver of the vehicle S after the seat belt operating unit 4 operates the seat belt as described above, and the result of the reaction detection unit 111 Based on the control of the vehicle S. Therefore, the vehicle control device 1 can specify the driver's state by directly detecting the reaction of the driver of the vehicle S, and can control the vehicle S appropriately according to the driver's state. As a result, the vehicle control device 1 can improve the accuracy of determining whether or not the physical condition change has occurred in the driver of the vehicle S, and can safely protect the driver having the physical condition change.
