Description

  The present invention relates to a driving posture adjusting device capable of adjusting a driving posture of a driver by moving a seat body and a brake pedal of a vehicle in the front-rear direction separately by control means.

Some vehicles include a driving posture adjusting device that changes the front and rear positions of a seat body or a brake pedal, a reclining angle, and the like by driving a motor.
For example, the position of the seat body includes a driving position when the driver drives and a boarding position when the driver gets on.
The driving position is a position set so that the steering wheel, the brake pedal, and the like can be operated in a natural posture. However, when getting on and off, since the steering wheel extends on the seat body, it may not be easy to get on and off.
Therefore, it is preferable to set the boarding position behind the driving position so that the driver can easily board.

Patent Document 1 describes a technique for detecting the driver's getting-on / off operation and controlling the position of the seat body. The detection of getting on and off is determined by the position of the shift lever.
That is, when the shift lever is switched to the parking position, the getting-off operation is detected, and the seat body is changed from the driving position to the boarding position. On the other hand, when the shift lever is switched from the parking position to another position, the boarding operation is detected, and the seat body is changed from the boarding position to the driving position.

JP-A-5-338482

According to the technique of Patent Document 1, the seat position is changed by the shift lever switching operation. As a precondition, it is necessary to start the engine at the boarding position.
However, generally, when starting the engine, there is one that performs the engine starting operation with the brake pedal depressed. At this time, if the boarding position is located behind the driving position, the seat body and the brake pedal are separated from each other than in the driving position, and the driver starts the engine with a posture such as forcibly extending the foot. It becomes. As described above, when the boarding position is set to the rear, there is a problem in that an engine starting operation such as a brake pedal operation cannot be performed smoothly unless an unnatural posture is taken.

  Accordingly, an object of the present invention is to provide a driving posture adjusting device that can smoothly perform an engine starting operation without impairing the riding performance.

  In order to achieve the above object, the first characteristic configuration of the driving posture adjusting apparatus according to the present invention is capable of adjusting the driving posture of the driver by moving the vehicle seat body and the brake pedal in the front-rear direction separately by the control means. In the driving posture adjusting device, when the engine is started, the seat body is positioned behind the normal driving position, and the brake pedal is set at a boarding position separated from the seat body by a preset distance. is there.

This configuration enables the driver to start the engine with a natural posture when the driver is seated. Usually, the position of the seat body on which the driver can easily get on is when the seat body is located behind the driving position.
On the other hand, the driver can easily start the engine when the seat body is in the driving position. At this time, the brake pedal is located at a preset distance from the seat body, and the driver can operate the brake pedal without difficulty.

The brake pedal is movable in the front-rear direction independently of the seat body. Therefore, even when the seat body is located behind the driving position, the brake pedal can be set to be located at the preset distance from the seat body. Thus, in the present invention, the boarding position refers to a state in which the seat body is located behind the driving position and the distance between the seat body and the brake pedal is set to a preset distance.
With this configuration, the driver can operate the brake pedal without difficulty without impairing the riding performance, so that the engine can be started smoothly from the riding operation.

  The second characteristic configuration of the driving posture adjusting apparatus according to the present invention is that the movement of the seat body to the riding position and the movement of the brake pedal are performed at different timings.

  In this configuration, the seat body is moved to the boarding position, and the brake pedal is moved after the driver is seated, so that the seat body and the brake pedal can be set to the boarding position having the preset distance. At this time, since the driver can sit on the seat body before the brake pedal moves, it is difficult for the driver to be interfered by the brake pedal at the time of sitting. Therefore, with this configuration, the operability for starting the engine is improved and the ride quality is excellent.

  A third characteristic configuration of the driving posture adjusting apparatus according to the present invention is that when the engine is stopped, only the seat body is changed from the driving position to the riding position.

If the seat body is changed to the position where the passenger gets on / off in advance when the engine is stopped as in this configuration, it is easier to get off and the next boarding operation becomes easier.
Further, if the position of the seat body is changed immediately before the engine is started, the engine cannot be reliably started if the electromotive force of the battery decreases after the position change. However, it can be considered that the battery is fully charged when the engine is stopped. In this way, when the battery state is good, if the seat body is moved, the load on the battery can be reduced.

  A fourth characteristic configuration of the driving posture adjusting apparatus according to the present invention includes a portable device having unique identification information, and when the portable device enters a predetermined range from the vehicle, the boarding position of the seat body is identified. The point is to adjust according to the information.

  In this configuration, for example, when the driver holding the portable device approaches the vehicle and the portable device enters the predetermined range with respect to the vehicle, the position of the seat body is changed. In that case, since it is set as the boarding position according to identification information, even if it is a case where a plurality of drivers share the same vehicle, the seat body can be positioned at a position according to the body shape of each driver. Therefore, with this configuration, the seat body and the brake pedal can be set to the optimal boarding position for each driver.

Embodiments of the present invention will be described below with reference to the drawings.
The present invention is a driving posture adjusting device that can adjust a driving posture of a driver by moving a seat body of a vehicle, and is configured so that an engine starting operation can be smoothly performed without impairing the riding performance.

Since the seat body is positioned behind the driving position when the driver gets on, the driver can get on smoothly and has excellent riding performance.
When starting the engine, an engine start operation such as an ignition key operation may be performed with the brake pedal depressed. If the engine starting operation is performed at a seat position with excellent rideability, the engine starting operation is performed in a state where the seat body is located behind the driving position. For this reason, it is difficult for the driver to perform engine starting operation such as operation of a brake pedal.

  Therefore, the driving posture adjusting device Y is configured so that the driver can easily operate the brake pedal when starting the engine without impairing the rideability (see FIG. 1).

  As shown in FIG. 1 (a), a vehicle seat apparatus X includes a seat back 11, a headrest 12, and a seat main body 1 having a seating surface on which a driver is seated. And a slide mechanism 2 that slides the seat body 1 in the front-rear direction of the vehicle. The seat device X of the present embodiment is a so-called power seat that electrically slides the seat body 1.

The slide mechanism 2 includes a position adjusting means 21 for setting the position of the seat body 1, a pair of lower rails 22 fixed to the floor of the vehicle, and a pair of movable along the lower rail 22 in the longitudinal direction of the vehicle. And an upper rail 23.
The position adjusting unit 21 includes a storage unit 24 that stores the position of the seat body 1, a motor that serves as power for adjusting the position of the seat body 1 in the front-rear direction, a control unit 25 that controls driving of the motor, and the like.

The driving position can be adjusted according to each driver. Each driver can perform a steering operation, a brake operation, an ignition key operation, etc. in a natural posture within the range to be adjusted. At this time, the brake pedal 3 is located at a preset distance D from the seat body 1. The preset distance D is a distance at which the driver can operate the brake pedal with a natural posture without taking an unnatural posture such as the driver forcibly extending his / her foot.
The preset distance D is, for example, a distance from the approximate center of the seat body 1 to the brake pedal 3.

  As shown in FIG. 1B, in the driving posture adjusting apparatus Y of the present invention, the distance between the seat main body 1 and the brake pedal 3 is set in advance even when the seat main body 1 is located behind the driving position. The distance is set to be separated by the set distance D.

The brake pedal 3 is configured to be movable in the front-rear direction independently of the seat body 1 by a pedal moving mechanism 31. The pedal moving mechanism 31 may have any configuration as long as the mechanism moves the brake pedal 3 in the front-rear direction with respect to the traveling direction of the vehicle. In the case of positioning from the driving position to the boarding position, the pedal moving mechanism 31 moves the brake pedal 3 backward.
The operation of the seat body 1 in the front-rear direction may include a certain amount of vertical movement. Accordingly, the pedal movement mechanism 31 is configured to move the brake pedal 3 diagonally backward, for example. Also good.
The pedal moving mechanism 31 is connected to the position adjusting means 21 for setting the position of the seat body 1 and controls the movement of the seat body 1 and the brake pedal 3 independently or simultaneously. However, a position adjusting means for controlling only the pedal moving mechanism 31 may be provided separately.

  In the device of the present invention, the driver can operate the brake pedal without difficulty at the driving position, while the driver can operate the brake pedal without difficulty when starting the engine even at the riding position. .

  The movement of the seat body 1 to the boarding position and the movement of the brake pedal 3 may be performed simultaneously. However, in view of a state in which the driver can easily get on and off, the movement of the seat body 1 to the boarding position and the movement of the brake pedal 3 can be performed at different timings.

That is, the seat body 1 is moved to the boarding position, and the brake pedal 3 is moved after the driver is seated, so that the seat body 1 and the brake pedal 3 can be set to the boarding position having the preset distance D. . At this time, since the driver is seated on the seat body 1 before the brake pedal 3 moves, the driver is less likely to be interfered with the brake pedal 3 during the seating.
The brake pedal 3 can be moved after the driver is seated and after the door is closed (FIG. 2: # 11 to # 13). Normally, when the door is closed, the driver is seated and immediately enters a driving state. When this state is detected, it is reasonable for the brake pedal 3 to move and the seat body 1 and the brake pedal 3 to be in the boarding position having the preset distance D.
In FIG. 2, the driver's recognition of the seating is determined based on whether or not the ignition key is inserted.

Further, when the engine is stopped, only the seat body 1 can be changed from the driving position to the boarding position (FIG. 3: # 21 to # 23). As described above, when the seat body 1 is changed to the position where the passenger gets on and off in advance when the engine is stopped, it is easy to get off and the next boarding operation becomes easy.
The seat body 1 and the brake pedal 3 may be in the boarding position when the engine is stopped.
When the engine is stopped, the battery can be considered fully charged. Thus, when the battery condition is good, the load of the battery can be reduced by moving the seat body 1 which is heavy and has a high moving load.
The engine stop in this case refers to a case where the driver intentionally stops the engine, and excludes a natural engine stop state such as an idling stop, for example.

The brake pedal 3 is set to a preset distance D from the seat body 1, and this distance D differs depending on the body shape of each driver. When a plurality of drivers share the same vehicle, it is convenient if the boarding position can be set at the seat position corresponding to each driver.
Therefore, this apparatus can use a wireless remote control system using the portable device 4 having unique identification information. This is because the portable device 4 recognizes the portable device 4 when, for example, the driver touches the door handle or operates the operation unit provided in the portable device while the portable device 4 is within a predetermined range from the vehicle. The door is unlocked.

The vehicle is provided with a recognition means 41 that receives a signal from the portable device 4 and recognizes the presence of the portable device 4.
The portable device 4 holds identification information for identifying each driver. When the recognition unit 41 recognizes the portable device 4, the position adjustment unit 3 determines the boarding position of the seat body 1 according to the identification information. Adjust (FIG. 4: # 31 to # 33). For this reason, even when a plurality of drivers share the same vehicle, the positions of the seat body 1 and the brake pedal 3 are set to the optimal boarding position for each driver according to the body shape of each driver. be able to. Even in this case, as described above, the movement of the seat body 1 and the movement of the brake pedal 3 may be performed at different timings.
Therefore, the driver can operate the brake pedal without difficulty when starting the engine, and can smoothly start the engine.

  The present invention can be applied to a vehicle that can adjust the driving posture of the driver by moving the seat body.
