Attention calling system and vehicle seat controlling system

1. An attention calling system for a vehicle seat having one or more drive devices incorporated therein, the attention calling system comprising:

an operating member, and

a controller configured to:

control, in a case where the vehicle is in a non-attention calling state and in response to an operation of the operating member by a seated person, the one or more drive devices so that the vehicle seat or a predetermined part of the vehicle seat moves in both positive and negative directions at a predetermined speed, thereby adjusting a position of the vehicle seat or a position of the predetermined part of the vehicle seat;

acquire vehicle information;

determine whether the vehicle information is indicating an attention state in which the seated person's attention should be called; and

control the one or more drive devices so that the vehicle seat or the predetermined part of the vehicle seat reciprocally moves in both the positive and negative directions with reference to a current position at a speed higher than the predetermined speed, in correspondence to the attention state when it is determined by the controller that the vehicle information is indicating the attention state.

2. The attention calling system according to claim 1 ,

wherein a drive signal that is applied to the one or more drive devices by the controller has a magnitude and a period by which a vibration, which can be physically sensed by the seated person, is generated at the vehicle seat or the predetermined part of the vehicle seat.

3. The attention calling system according to claim 1 ,

wherein the vehicle information comprises collision beforehand detection information, and

wherein when the collision beforehand detection information is acquired, the controller controls the one or more drive devices so that at least the vehicle seat reciprocally moves in a front-rear direction.

4. The attention calling system according to claim 1 ,

wherein the controller is configured to apply a drive signal to each of the one or more drive devices so that a moving amount in the positive direction and a moving amount in the negative direction are the same with reference to the current position.

5. The attention calling system according to claim 1 , further comprising a setting unit configured to change the one or more drive devices to be controlled by the controller in correspondence to a content of the vehicle information.

6. A vehicle seat controlling system comprising:

a vehicle seat for a vehicle;

a drive device incorporated inside the vehicle seat;

an operating member; and

an electronic control unit configured to perform:

controlling, in a case where the vehicle is in a non-attention calling state and in response to an operation of the operating member by a seated person, the drive device so that the vehicle seat or a predetermined part of the vehicle seat moves in both positive and negative directions at a predetermined speed, thereby adjusting a position of the vehicle seat or a position of the predetermined part of the vehicle seat,

acquiring vehicle information,

determining whether the vehicle information indicates an attention state in which the seated person's attention should be called, and

controlling the drive device so that the vehicle seat or the predetermined part of the vehicle seat reciprocally moves in both the positive and negative directions with reference to a current position at a speed higher than the predetermined speed, in response to determining that the vehicle information indicates in the attention state.

7. The attention calling system according to claim 1 ,

wherein the predetermined speed is an adjustment speed at which the position of the vehicle seat or the position of the predetermined part of the vehicle seat is moved when being adjusted to change a seating position for the seated person.
