In each figure, the arrow FR indicates the front of the vehicle, the arrow W indicates the vehicle width direction, and the arrow UP indicates the upper part of the vehicle.

[Constitution]
(Composition of the passenger compartment (front seat))
As shown in FIG. 1, a front seat 14 and a rear seat 16 which are driver's seats are arranged in the passenger compartment 12 of the vehicle 10. The front seat 14 has a seat cushion 18, a seat back 20, and a headrest 22.

As shown in FIG. 2, inside the seat back 20, a first air bag 24A and a second air bag 24B (hereinafter, may be referred to as "air bags 24A, 24B") expanded by a predetermined pressure are provided. Two are arranged in parallel. The air bags 24A and 24B extend vertically inside the seat back 20, respectively, and are arranged side by side in the vehicle width direction. Further, the positions of the air bags 24A and 24B in the seat back 20 are set to positions where the backs of the occupants P seated on the front seat 14 (seat cushion 18) are brought into contact with each other.

(Structure of exercise support device for vehicles)
As shown in FIG. 3, the vehicle motion support device 26 including the air bags 24A and 24B has a first pressure sensor 28A and a second pressure sensor 28B (hereinafter, “pressure”) for detecting the internal pressures of the air bags 24A and 24B, respectively. Sensors 28A, 28B ”), a seat ECU 30 that generates a control signal output to an application described later based on the internal pressure change of the air bags 24A, 24B detected by the pressure sensors 28A, 28B, and the sheet ECU 30. It is equipped with.

In the seat ECU 30, the internal pressure values of the air bags 24A and 24B are read from the pressure sensors 28A and 28B at predetermined time intervals. When a request signal from an application described later is input, the seat ECU 30 takes a difference between the internal pressure value immediately after the input and the internal pressure value read last time, and detects the amount of change in the internal pressure of each of the air bags 24A and 24B. Based on this amount of change in internal pressure, a control signal in which either the left or right displacement direction and the displacement speed are set is output to the application side.

The air bags 24A and 24B and the pressure sensors 28A and 28B correspond to the body motion detecting means. Further, the seat ECU 30 corresponds to the control means.

(Car navigation device)
The car navigation device 32 has a car navigation ECU 34 and a monitor 36. The monitor 36 corresponds to the display means.

An exercise application (hereinafter, may be referred to as an "application") is installed in the car navigation ECU 34. This application is a game in which the character aims at the goal while avoiding obstacles on the game screen, and the character performs an operation of avoiding obstacles to the left and right based on a control signal from the seat ECU 30.

When the exercise application is started, the game screen is displayed on the monitor 36.

Further, the car navigation ECU 34 and the seat ECU 30 are connected by a signal line 38 of a CAN (Controller Area Network). Therefore, when the application is started by the car navigation ECU 34, the displacement direction of the character from the car navigation ECU 34 to the seat ECU 30 and at the timing when the character avoids the obstacle on the game screen (the obstacle approaches the character on the game screen). The configuration is such that a request signal requesting a displacement speed (control signal) is output. By inputting this request signal, the seat ECU 30 generates a control signal based on the movement of the body of the occupant P and outputs it to the car navigation ECU 34.

On the other hand, the application installed in the car navigation ECU 34 moves the character on the game screen based on this control signal. In the case of an appropriate control signal, the character avoids obstacles on the game screen and shifts to a new game screen. On the other hand, in the case of an inappropriate control signal, the character stops at a scene where the character collides with an obstacle.

[Action]
Next, the operation of the motion support device 26 for a vehicle configured in this way will be described.

When the occupant P selects an exercise application on the car navigation device 32, the application installed on the car navigation ECU 34 is activated, and the game screen of the application is displayed on the monitor 36 of the car navigation device 32.

Specifically, the monitor 36 displays a game screen in which an obstacle approaches the character. When the obstacle approaches the character on the game screen and the character needs to take measures to avoid the obstacle, the application (car navigation ECU 34) outputs a request signal to the seat ECU 30.

On the other hand, the occupant P seated on the front seat 14 presses the seat back 20 in order to cause the character to perform a predetermined operation at a timing that can avoid obstacles. For example, when the occupant P wants to move the character to the right on the game screen, the occupant P strongly presses the right side of the seat back 20.

Hereinafter, the control signal creation control in the seat ECU 30 will be described with reference to the flowchart shown in FIG.

When the request signal from the car navigation ECU 34 is input to the seat ECU 30 (FIG. 5, step S10 (hereinafter, “FIG. 5” is omitted)), the internal pressure change amount ΔP1 of the first air bag 24A is detected. Specifically, the seat ECU 30 reads the internal pressure value of the first air bag 24A detected by the first pressure sensor 28A at predetermined time intervals. Therefore, when the request signal is input, as shown in FIG. 4A, the difference between the internal pressure value P11 of the first air bag 24A immediately after the input and the internal pressure value P12 of the previous first air bag 24A is taken. Then, the internal pressure change amount ΔP1 of the first air bag 24A is detected (step S12).

Similarly, in the seat ECU 30, when the request signal is input, as shown in FIG. 4B, the internal pressure value P21 of the second air bag 24B immediately after the input and the internal pressure value P22 of the previous second air bag 24B By taking the difference between the above, the amount of change in the internal pressure ΔP2 of the second air bag 24B is detected (step S14).

Subsequently, the seat ECU 30 determines whether or not the internal pressure change amount ΔP1 of the first air bag 24A is larger than the internal pressure change amount ΔP2 of the second air bag 24B (step S16).

If the internal pressure change amount ΔP1 of the first air bag 24A is larger than the internal pressure change amount ΔP2 of the second air bag 24B (Y in step S16), the displacement direction corresponds to the right direction and the displacement speed corresponds to the internal pressure change amount ΔP1. A control signal set to the speed V1 is generated and output to the car navigation ECU 34 (step S18).

If the internal pressure change amount ΔP1 of the first air bag 24A is equal to or less than the internal pressure change amount ΔP2 of the second air bag 24B (N in step S16), the internal pressure change amount ΔP2 of the second air bag 24B is the internal pressure of the first air bag 24A. It is determined whether or not the amount of change is larger than ΔP1 (step S20).

If the internal pressure change amount ΔP2 of the second air bag 24B is larger than the internal pressure change amount ΔP1 of the first air bag 24A (Y in step S20), the displacement direction corresponds to the left direction and the displacement speed corresponds to the internal pressure change amount ΔP2. A control signal set to the speed V2 is generated and output to the car navigation ECU 34 (step S22).

If the internal pressure change amount ΔP2 of the second air bag 24B is not larger than the internal pressure change amount ΔP1 of the first air bag 24A (if ΔP1 = ΔP2) (N in step S20), it is immovable as it does not move to the left or right. A control signal to that effect (displacement direction pear, displacement speed 0) is generated and output to the car navigation ECU 34 (step S24).

When any of the control signals is generated as described above, the process waits until the request signal is input again (step S10).

On the other hand, in the car navigation ECU 34 to which the control signal is input from the seat ECU 30, the character is moved based on the control signal input on the application. For example, when the displacement direction is to the right and the displacement speed is set to the speed V1 and the control signal, the character is moved to the right at the speed V1 on the game screen. If this displacement direction (here, the right direction) and the displacement speed are appropriate, the character avoids obstacles on the game screen and moves to the next game screen.

When it is time for the character to avoid a new obstacle on the next game screen, a request signal is output again from the car navigation ECU 34 to the seat ECU 30, and the above control is repeated.

On the other hand, if the displacement direction or displacement speed set by the control signal is not appropriate, the character collides with an obstacle on the game screen. In this case, for example, it is conceivable to restart the game from the scene where the colliding obstacle approaches, or restart the game from the initial screen as the game is over.

As described above, in the vehicle exercise support device 26 according to the present embodiment, the game screen of the exercise application is displayed on the monitor 36 of the car navigation device 32. As a result, the occupant P presses his back against the seat back 20 (moves his body) so that the character on the game screen avoids obstacles. As a result, in the seat ECU 30, the displacement direction of the character in the game and the displacement direction of the character in the game are based on the difference in the amount of change in the internal pressure of the air bags 24A and 24B arranged on the left and right of the seat back 20 and the amount of change in the internal pressure of the larger air bag. A control signal for which the displacement speed is set is generated and output to the car navigation ECU 34. By this control signal, the character moves in the displacement direction set in the control signal at the displacement speed on the game screen, and if the obstacle on the game screen can be avoided, the character moves to the next game screen.

In this way, the occupant P moves the character on the game screen in a desired displacement direction and displacement speed by pressing the back against the seat back 20 according to the game content of the application, and avoids obstacles on the game screen. be able to. Since the movement of the body must be changed according to the size of the obstacle, the approaching speed, and the like, the occupant P can repeat the exercise without getting tired.

In addition, since the application is set so that the character on the game screen avoids obstacles, the occupant P concentrates on making the character avoid obstacles, and compares it with the one that moves the body as displayed on the screen of the monitor 36. The setting is such that you won't get bored.

It is not something that will be done. For example, the seat cushion 18 is also provided with air bags on the left and right, and the vertical direction (displacement direction) and the displacement speed of the character can be set based on the difference in the amount of change in the internal pressure of the left and right air bags and the amount of change in the internal pressure. As a result, the character can move not only left and right but also up and down, and the variation of the game increases and the variation of the movement content of the occupant P also increases.
