  The seat actuator 12 is a member for actuating a seat on which an occupant is seated, that is, a seat back (back) of the seat, a side support of a side portion of the seat surface, and the like. It may be an actuator for actuating the part, or an actuator using any driving energy such as electricity, pressurized oil, compressed air, or the like. Further, the seat actuator 12 may be one that periodically or entirely changes the position of the seat as an awakening operation, that is, that that vibrates or shakes. In the embodiment of the present invention, the seat actuator 12 will be described mainly as an electric actuator incorporated in a reclining mechanism that changes the angle of the seat back. It is desirable that the seat actuator 12 can change the angle of the seat back with respect to the seating surface, for example, in the range of about 90 to 180 degrees. Furthermore, in the embodiment of the present invention, it is assumed that the seat back of the seat on which the driver is seated is excluded.

  The camera 13 includes an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS), and is disposed inside the vehicle to photograph the occupant. In this case, it is desirable to irradiate the occupant with infrared light and acquire images of the occupant's posture, face, and the like by the camera 13.

  Further, the seat sensor 14 is disposed on each seat, and measures the weight of the occupant sitting on the seat, for example, by measuring the weight, or measures the heart rate for the wakefulness determination of the occupant. You can also.

  In the embodiment of the present invention, the seat actuator 12, the camera 13, and the seat sensor 14 are communicably connected to the navigation device 11, and the navigation device 11 is based on signals received from the camera 13 and the seat sensor 14. If it is determined that the occupant is sleeping, the operation of the seat actuator 12 is controlled so that when the vehicle arrives at the destination, the awakening level corresponding to the destination attribute and the time zone is obtained. The occupant is awakened.

  Therefore, the navigation device 11 has a destination attribute acquisition unit that acquires a set destination attribute, an occupant presence / absence determination unit that determines the presence / absence of an occupant, and a current position acquisition that acquires the current position of the vehicle from the viewpoint of functions. Section, a route acquisition unit that acquires a route from the current position of the vehicle to the destination, an estimated arrival time acquisition unit that acquires the predicted arrival time to the destination, the timing, strength, etc. Awakening action content determination section for determining, awakening action timing determining section for determining the start timing of the awakening action, an awakening action intensity determining section for determining the intensity of the awakening action, and awakening action start for setting a point at which the wakeup operation is started A point setting unit, a sleep determination unit that determines whether or not the occupant is asleep, an awakening determination unit that determines whether or not the occupant has awakened, and an awakening motion that controls the operation to awaken the occupant The control unit 17, a time zone determination unit that determines what time zone the current time acquired from the time measuring means belongs to, a destination attribute storage unit that stores an awakening action target attribute as a destination attribute, and a destination An awakening action content storage unit that stores the contents of the awakening action corresponding to the attribute of the ground and the time zone.

  Here, the awakening action target attribute is an attribute indicating that the destination is a destination where the awakening action is to be performed, and is classified into several types from the viewpoint of the required degree of awakening. It is classified. In the embodiment of the present invention, for example, a case will be described in which a first attribute that requires a relatively high arousal level and a second attribute and a third attribute that do not require a relatively high arousal level are described. .

  As the place included in the first attribute, for example, a school, a workplace, and the like are conceivable. Here, as illustrated in FIG. 2, the place included in the first attribute is referred to as “company”. In addition, as a place included in the second attribute, for example, a place where the user can rest or sleep again after arrival, such as a home, can be considered. Here, the place included in the second attribute is Called “Home”. Further, as a place included in the third attribute, for example, when arriving in the morning, such as an inn or a hotel in a tourist spot, a high arousal level is required for sightseeing, etc., and it arrived at night In some cases, a place where the person can rest or sleep again is considered, and the place included in the third attribute is referred to as “accommodation facility”.

  In the awakening action content storage unit, a table in which the awakening action target attribute of the destination as shown in FIG. 2 and the awakening action pattern corresponding to the time zone of arrival at the destination are stored is prepared. Remember. Note that S (Standard), Fa (Fast), Sl (Slow), Fo (Forte), and So (Soft) shown in the table indicate wake-up action patterns, and S, Fa, and Sl indicate timing. In the figure, Fo and So indicate strength. That is, S means normal timing, Fa means early timing, and S1 means late timing. Also, Fo means stronger, that is, abrupt wakeup, and So weaker, that is, wakes up slowly.

  The table shown in FIG. 2 wakes up early strongly when it is important to require a relatively high degree of wakefulness, and weakly wakes up late when it is not important when a relatively high degree of wakefulness is not required. It is created based on the basic idea.

  The awakening action target attribute is set in advance for various facilities included in the facility data of the data storage unit and stored in the destination attribute storage unit, and the destination attribute acquisition unit is It is assumed that the destination attribute storage unit is accessed and an attribute set for the facility as the set destination is acquired. When the awakening action content determination unit determines that the acquired destination attribute includes the awakening action target attribute, the acquired awakening action target attribute and the acquired destination awakening action target attribute are obtained. The content of the awakening action is determined based on the time zone where it is predicted to arrive at the destination. The awakening action content determination unit includes a waking action timing determination unit and a waking action intensity determination unit, and the awakening action timing determination unit and the awakening action intensity determination unit respectively determine the start timing and intensity of the awakening action.

  Then, the awakening operation start point setting unit reversely calculates a point from which to start the awakening operation from the destination based on the predicted arrival time to the destination acquired by the predicted arrival time acquisition unit and the start timing of the awakening operation. Set. In the table as shown in FIG. 2, for example, Fa is 10 minutes before the arrival of the wake-up action, S is 5 minutes before the start of the wake-up action, and S1 is the start timing of the wake-up action. Suppose it is defined as one minute before arrival. For example, when the destination attribute is home and the predicted arrival time is, for example, 21:00, that is, when the predicted time zone is night, the pattern of the awakening action is “ S / So ”, the start timing of the awakening action is 5 minutes before arrival, and a point predicted to pass 5 minutes before the predicted arrival time on the route to the destination, that is, home is Set as awakening start point.

  The occupant presence / absence determination unit determines whether an occupant is seated on a seat other than the driver's seat based on a signal from the seat sensor 14. The occupant presence / absence determination unit may process the image inside the vehicle acquired by the camera 13 to determine the presence / absence of the occupant.

  The sleep determination unit determines whether the occupant is sleeping based on the occupant image acquired by the camera 13. For example, the image of the occupant's face is processed to extract the area around the eyes. If the eyelid is closed, it is determined that the person is sleeping, and if the eyelid is open, the person is awakened, that is, sleeps. Judge that it is not. Further, for example, it can be determined that the occupant is lying down if the posture is lying down, and it can be determined that the occupant is not sleeping if the upper body of the occupant is nearly upright. Further, the sleep determination unit obtains the angle of the seat back from the seat actuator 12, determines that the seat back is tilted and the angle with the seat surface is close to 180 degrees, determines that it is sleeping, and the seat back stands up and sits down. If the angle with the surface is close to 90 degrees, it may be determined that the person is not sleeping. In addition, since a person tends to have a lower heart rate than a sleepless person when the person becomes sleepy, the increase / decrease in the heart rate may be added to the sleep determination condition to improve the determination accuracy of whether or not the person is asleep. .

  And the said awakening determination part determines whether the said passenger | crew is awakening based on the passenger | crew's image which the camera 13 acquired similarly to the said sleep determination part. For example, the image of the occupant's face is processed to extract the area around the eyes, and if the eyelid is closed, it is determined that it is asleep, that is, it is not awake, and if the eyelid is open, it is awake Is determined. Further, for example, it can be determined that the passenger is not awake if the occupant's posture is lying, and can be determined to be awake if the upper body of the occupant is in an upright state. Further, the sleep determination unit obtains the angle of the seat back from the seat actuator 12, determines that the seat back is tilted and is not awake if the angle with the seat surface is close to 180 degrees, and the seat back stands up. If the angle with the seat is close to 90 degrees, it may be determined that the user is awake.

  In addition, the awakening action control unit 17 controls the seat actuator 12 of the seat on which the occupant is seated when the vehicle reaches the point set by the awakening action start point setting unit, and the awakening action intensity determination unit determines Causes a strong awakening action. In the present embodiment, the operation for changing the angle of the seat back and the operation for vibrating or swinging all or part of the seat are described as the awakening operation. Note that the awakening action strength determination unit determines the strength of the awakening action based on the pattern of the awakening action in the table as shown in FIG. Here, when the seat actuator 12 changes the angle of the seat back, the awakening operation is an operation of raising the seat back, that is, the seat back that is tilted until the angle with the seat surface is close to 180 degrees. This is an operation of raising the angle until the angle approaches 90 degrees. Further, when the seat actuator 12 vibrates or shakes all or part of the seat as an awakening operation, the intensity of the awakening operation is changed by changing the period, amplitude, and the like. If the seat actuator 12 vibrates or swings the seat with a plurality of motors, the awakening action pattern is strengthened, that is, when it is Fo, all the motors are activated, and the awakening action pattern Is weak, that is, when it is So, only some motors are operated. In the example shown in FIG. 2, the intensity of the awakening action is set to two levels of Fo and So, but can be set to three or more levels as necessary.

  The current position acquisition unit acquires the current position of the vehicle detected by a normal current position detection process executed by the navigation device 11, and the route acquisition unit performs a normal navigation process executed by the navigation device 11. The route searched by one route search process is acquired. Similarly, the predicted arrival time acquisition unit also acquires the predicted arrival time predicted based on the route searched by the route search process.

  Next, the operation of the passenger awakening system 10 having the above-described configuration will be described. First, the operation for setting the awakening operation will be described.

  FIG. 3 is a flowchart showing an operation for setting the awakening operation of the occupant awakening system in the first embodiment of the present invention.

  First, when the engine of the vehicle is activated and the navigation device 11 starts operating, the navigation device 11 determines whether or not a destination is set by an occupant such as a driver. When the destination is not set, the operation flow for setting the awakening operation is exited. If the destination is set, the attribute of the set destination is acquired.

  Subsequently, the navigation device 11 determines whether the attribute of the destination includes the awakening action target attribute, that is, whether one of the acquired attributes is the awakening action target attribute. If the attribute is not the awakening action target attribute, the operation flow for setting the awakening action is exited.

  When the attribute is the awakening action target attribute, the navigation device 11 determines whether there is an occupant other than the driver. When there is no occupant, the operation flow for setting the awakening operation is exited. Further, when there is an occupant, the navigation device 11 acquires the current position of the vehicle. Subsequently, a route from the current position to the destination is acquired, and further, an estimated arrival time at the destination is acquired.

  And the said navigation apparatus 11 sets the point which starts a wake-up operation | movement, determines the intensity | strength of a wake-up operation | movement, and complete | finishes the operation | movement flow which sets a wake-up operation | movement.

Next, a flowchart will be described.

Step S2: Exit from the operation flow for setting the awakening operation.
Step S3: The set destination attribute is acquired.
Step S4: It is determined whether or not the attribute is an awakening action target attribute. If it is an awakening action target attribute, the process proceeds to step S6, and if it is not an awakening action target attribute, the process proceeds to step S5.
Step S5: Exit from the operation flow for setting the awakening operation.
Step S6: Determine whether there are passengers other than the driver. If there is an occupant other than the driver, the process proceeds to step S8, and if there is no occupant other than the driver, the process proceeds to step S7.
Step S7: Exit from the operation flow for setting the awakening operation.
Step S8: Obtain the current position.
Step S9: Obtain a route from the current position to the destination.
Step S10: Obtain an estimated arrival time at the destination.
Step S11: A point for starting the awakening operation is set.
Step S12: The intensity of the awakening action is determined, and the operation flow for setting the awakening action is terminated.

  Next, the operation for executing the awakening operation will be described.

  FIG. 4 is a flowchart showing an operation of executing the awakening operation of the occupant awakening system in the first embodiment of the present invention.

  The navigation device 11 starts an operation flow for executing a wake-up operation every predetermined cycle (for example, every 100 [msec]). Then, the current position of the vehicle is acquired, and it is determined whether or not the current position is a point for starting the awakening operation set in the operation flow for setting the awakening operation. Here, when it is not the point where the awakening operation is started, the operation flow for executing the awakening operation is exited.

  In addition, when the point is where the awakening operation is started, the navigation device 11 determines whether an occupant other than the driver is sleeping. And when the said passenger | crew is not sleeping, it escapes from the operation | movement flow which performs an awakening operation | movement.

  When the occupant is asleep, the navigation device 11 controls the operation of the seat actuator 12 to start the awakening operation. Thereby, the seat actuator 12 executes the awakening operation with the intensity determined in the operation flow for setting the awakening operation.

  Then, the navigation device 11 determines whether or not the occupant is awake. Here, if the occupant is not awake, the seat actuator 12 is made to continue the awakening operation, and the determination as to whether the occupant is awake is repeated. When the occupant is awake, the operation flow for executing the awakening operation is terminated.

Next, a flowchart will be described.
Step S21: It is determined whether or not it is a point for starting the set awakening action. If it is a point to start the set awakening action, the process proceeds to step S23, and if it is not a point to start the set awakening action, the process proceeds to step S22.
Step S22: Exit from the operation flow for executing the awakening operation.
Step S23: It is determined whether an occupant other than the driver is sleeping. If an occupant other than the driver is sleeping, the process proceeds to step S25, and if an occupant other than the driver is not sleeping, the process proceeds to step S24.
Step S24: Exit from the operation flow for executing the awakening operation.
Step S25 The awakening operation is started.
Step S26: It is determined whether or not the occupant is awake. If the occupant is awake, the operation flow for executing the awakening operation is terminated, and if the occupant is not awake, the process returns to step S25.

  As described above, in the embodiment of the present invention, the occupant awakening system 10 controls the operation of the seat according to the destination and the time zone, and awakens the sleeping occupant. Thereby, the wakefulness level of the passenger can be set to an appropriate level corresponding to the destination and the time zone.

  For example, if the destination is a workplace such as a company and it is in the morning, by executing a strong awakening operation at an early timing, when the vehicle arrives at the destination, the occupant becomes a high awakening degree and arrives Enough activities can be performed immediately afterwards. Further, for example, when the destination is at home and is in the afternoon time zone, the occupant can walk at least when the vehicle arrives at the destination by executing a weak awakening operation at a normal timing. The degree of awakening can be adjusted to suit home activities. Furthermore, for example, if the destination is an accommodation facility and is in the night and late night hours, a weak awakening operation is performed at a later timing, so that the vehicle is sufficiently awakened even when it arrives at the destination. It's not easy to go to bed at the accommodation.

  Therefore, the occupant can perform an efficient operation at the destination, maintain a good health condition, and obtain satisfaction.

  In the embodiment of the present invention, the navigation device 11 includes a complete awakening achievement unit and an incomplete awakening achievement unit. When the awakening action content determination unit determines that the awakening action content should achieve complete awakening, the complete awakening achievement unit sets the start timing of the awakening action 30 minutes before the predicted arrival time at the destination. Set to, and set the intensity of the awakening action weaker. As a result, the awakening operation is started 30 minutes before the predicted arrival time at the destination and is performed slowly, so that the occupant is completely awakened when it arrives at the destination.

  In addition, when the awakening action content determination unit determines that the awakening action content is to achieve incomplete awakening, the incomplete awakening achievement unit sets the start timing of the awakening action to the time of arrival at the destination. , Set the intensity of the awakening action stronger. As a result, the awakening operation is started at the time of arrival at the destination and is abruptly performed. Therefore, the user does not get up and the passenger wakes up rapidly at the time of arrival at the destination, but becomes easy to go to bed again.
