Description

  The present invention relates to a control device that controls opening and closing of a passenger door provided in a vehicle.

  For vehicles such as buses, even if the driver inadvertently makes a mistake, the entrance / exit door will not open while the vehicle is running, or the vehicle will not start moving when the entrance / exit door is open. Various control devices have been proposed.

  For example, in Patent Document 1, when there is a vehicle door opening signal during traveling of the vehicle (that is, when the driver performs an operation of opening the vehicle door), the vehicle is traveling by the vehicle speed sensor. Control is performed so that the control device shifts to the prohibit mode, performs a reset operation when the vehicle stops, shifts to the permit mode, and then opens the vehicle door when there is a vehicle door open signal. A scheme is disclosed. In this control method, even if the driver performs an operation of opening the door while the vehicle is running, the door is not opened, and the door is opened only after a reset operation is performed when the vehicle is stopped.

  However, in the control method disclosed in Patent Document 1, for example, if the driver carelessly removes his / her foot from the foot brake while the vehicle is stopped and the door is opened, the vehicle seems to stop on the slope. In some cases, or when a creep phenomenon occurs in an automatic vehicle, the vehicle may start to move.

The inventors of the present invention have proposed a vehicle equipped with a control device that can solve this problem and can fully implement safety measures for opening and closing a door in Patent Document 2.
The vehicle proposed in Patent Document 2 includes a vehicle speed sensor for detecting the speed of the vehicle, a door opening / closing switch for opening / closing the door, a door opening / closing sensor for detecting the opening / closing state of the door, a parking brake, A driving force transmission device that transmits the driving force of the engine to the wheels, and a driving force transmission device that detects that the vehicle is stopped by the vehicle speed sensor and that the door is opened by the door opening / closing sensor. And a control device that prohibits transmission of the driving force and activates the parking brake. With this configuration, it is possible to prevent the vehicle from moving while the door is open when the vehicle starts.

  In Patent Document 2, in addition to the above configuration, a foot brake is further provided, and the control device detects that the door is closed by a door opening / closing sensor in a state where the parking brake is operated, and the foot brake is There is disclosed a vehicle configured to release a parking brake and permit transmission of a driving force by a driving force transmission device when it is determined that the vehicle is operating. With this configuration, when the vehicle starts, it is possible to start traveling safely from a state in which the door is closed.

  As disclosed in Patent Document 2, when the door opening / closing sensor detects that the door is closed and it is determined that the foot brake is operating, the parking brake is released and the driving force transmission device In the door opening / closing control device configured to allow transmission of driving force, a start prohibition lamp is further provided, and when the door is in an open state, the driving force transmission system is determined by a door opening detection signal obtained by the door opening / closing sensor. At the same time as the shut-off, a control method is conceivable in which a start prohibition lamp is turned on to prompt the driver not to start the vehicle. For example, the start prohibition light is turned on when the door is opened, and is turned off several seconds after the door is closed.

  However, in this system, when the foot brake is not depressed even when the door is closed, the start prohibition light is turned off, but the driving force transmission system is not connected. Therefore, the driver tries to start the vehicle because the start prohibition light is turned off, but the driving force transmission system is not connected, so that the driver may not start. In this case, if the stop location of the vehicle is on a slope, there is a problem that the vehicle is displaced against the driver's intention.

Under the condition that the foot brake is operating, connect the driving force transmission system, and after connecting the driving force transmission system, turn off the start prohibition light and release the accelerator interlock simultaneously with the start of the start prohibition light. And a control device.

In the device according to the present invention, even when the driver does not step on the foot brake with the door closed, the start prohibition lamp is lit and the accelerator interlock remains activated. Then, the driver steps on the foot brake, the driving force transmission system is connected, then the start prohibition light is turned off after a set time, and the accelerator interlock is released.
In this way, even if the door is closed, if the driver does not step on the foot brake, the driving force transmission system is not connected, but the start prohibition lamp is lit, so the driver is driven. It can alert or warn that the power transmission system is not connected.

Further, even if the driver overlooks the start prohibition light and starts the vehicle, the accelerator cannot be depressed because the accelerator interlock is activated. Therefore, the driver can be made aware that the driving force transmission system is not connected.
Therefore, it can be avoided that the driver misunderstands that the driving force transmission system is connected and starts the vehicle even though the driving force transmission system is not connected. Therefore, even when the vehicle is stopped on a slope, the vehicle can be prevented from sliding down.

  Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the component parts described in this embodiment are not intended to limit the scope of the present invention to that unless otherwise specified.

(Embodiment)
An embodiment in which the device of the present invention is applied to a route bus will be described with reference to FIGS. In FIG. 1, this route bus 10 is provided with a passenger entrance / exit door 12 provided in the center of the bus body and a door provided near the driver's seat to be switched by the driver to open and close the inner door 12. The open / close switch 14, the door open / close sensor 16 that detects the open / close state of the inner door 12, the vehicle speed sensor 18, the foot brake 20, and the driving force transmission system that connects the engine and the wheels 22 (not shown) are transmitted or cut off. And a driving force transmission device 24.

  Further, in the vicinity of the driver's seat, a start prohibition light 36 is provided that lights up when the inner door 12 of the route bus 10 is open and alerts or warns the driver. Further, an accelerator interlock 38 is provided that operates when the inner door 12 is opened.

  The parking brake 28 is supplied with compressed air from an air tank 32 through a pipe 34 in a state where the electromagnetic valve 30 is closed, and is exhausted from the brake chamber when the electromagnetic valve 30 is opened. When the electromagnetic valve 30 is opened, the compressed air in the brake chamber is exhausted, a brake shoe (not shown) provided inside the wheel 22 is spread outward, and the parking brake 28 is operated. Such a configuration of the parking brake 28 is conventionally known (see FIG. 2 of Patent Document 2 for a detailed configuration).

  The controller 26 opens and closes the middle door 12 according to the switching operation of the door opening / closing switch 14 by the driver, and detects the opened / closed state of the middle door 12 by the door opening / closing sensor 16. Further, the controller 26 detects the speed of the route bus 10 by the vehicle speed sensor 18. Further, the controller 26 stops the route bus 10 according to the foot brake 20 operated by the driver, and switches the electromagnetic valve 30 to operate the parking brake 28.

Further, the controller 26 controls the driving force transmission device 24 so that the inner door 12 is opened, and at the same time the driving force transmission system is shut off, the inner door 12 is closed, and the driver steps on the foot brake 20, and then the setting is made. After time I ₁ (for example, 0.35 seconds), the driving force transmission system is connected.
Further, the controller 26 turns on the start prohibition lamp 36 at the same time when the inner door 12 is opened, the inner door 12 is closed, and the driver steps on the foot brake 20, and then the set time I ₂ (for example, 1.0 second). After I ₁ <I ₂ ), the start prohibition lamp 36 is turned off.

Further, the controller 26 operates the accelerator interlock 38 simultaneously with the opening of the inner door 12, closes the inner door 12, and after the driver steps on the foot brake 20, simultaneously with the start prohibition light 36 (set time I _2). After), the accelerator interlock 38 is released.

  Next, the operation control operation of the route bus 10 by the controller 26 will be described with reference to FIGS. 2 and 3, when the route bus 10 starts traveling (step 1), the controller 26 detects the speed of the vehicle with the vehicle speed sensor 18, and waits until the vehicle stops (step 2). When the route bus 10 stops, the controller 26 detects the open / close state of the middle door 12 by the door open / close sensor 16 (step 3). If it is determined that the inner door 12 is closed, the controller 26 waits for the driver to switch the door opening / closing switch 14 (step 6).

  When the route bus 10 stops and the door opening / closing switch 14 is opened by the driver, the controller 26 determines that the route bus 10 is stopped and is safe, and opens the inner door 12 (step 7). ). That is, the controller 26 is safe because the vehicle speed sensor 18 confirms that the route bus 10 is stopped and opens the inner door 12.

When the inner door 12 is opened (step 7) or when it is determined in step 3 that the inner door 12 is opened, the controller 26 turns on the start prohibition lamp 36 as a safety measure (step 8). At the same time, the accelerator interlock 38 is operated (step 9).
At the same time, the transmission of the driving force by the driving force transmission device 24 is prohibited so that the driving force of the engine is not transmitted to the wheels 22 (step 10). At the same time, the electromagnetic valve 30 is opened and the parking brake 28 is operated. (Step 11). In this state, the route bus 10 can be reliably stopped and passengers can be safely boarded and exited.

  When the driving force transmission system is interrupted by the driving force transmission device 24, if the driver carelessly releases the foot brake 20, the route bus 10 may start to move. However, in this embodiment, since the parking brake 28 is operated, the route bus 10 can be reliably stopped.

  When the passenger gets on and off and the inner door 12 is closed, the opening / closing switch 14 is closed by the driver (step 12), the controller 26 closes the inner door 12 (step 13). Thereafter, the controller 26 closes the electromagnetic valve 30 on condition that the foot brake 20 is stepped on by the driver (step 14). As a result, compressed air is supplied from the air tank 32 to the brake chamber via the pipe 34, and the parking brake 28 is released (step 15).

Further, after the foot brake 20 is stepped on by the driver, transmission of the driving force transmission system is permitted after a set time I ₁ (for example, 0.35 seconds) (step 16).
Further, after the driving force transmission system is connected, that is, after a set time I ₂ (for example, 1.0 second, I ₁ <I ₂ ) after the foot brake 20 is depressed, the start prohibition lamp 36 is turned off ( At the same time, the accelerator interlock 38 is released (step 18).

  In this state, the route bus 10 can be operated. However, since the foot brake 20 is operated, the route bus 10 does not start on its own. After releasing the accelerator interlock in step 18, the controller 26 returns to step 1 and repeats the processing from step 1 to step 18 until the operation of the route bus 10 is terminated.

According to the present embodiment, even when the driver does not step on the foot brake 20 with the inner door 12 closed, the start prohibition lamp 36 is lit and the accelerator interlock 38 is kept operating. Then, the driver steps on the foot brake 20 to connect the driving force transmission system after the set time I ₁ , and then the start prohibition lamp 36 is turned off after the set time I ₂ and the accelerator interlock 38 is released. .
Thus, even if the inner door 12 is closed, if the driver does not step on the foot brake 20, the driving force transmission system is not connected, but the start prohibition light 36 is lit, It is possible to alert or warn the driver that the driving force transmission system is not connected.

Further, even if the driver overlooks the start prohibition light 36 and starts the route bus 10, the accelerator cannot be depressed because the accelerator interlock 38 is operating. Therefore, the driver can be made aware that the driving force transmission system is not connected.
Therefore, it can be avoided that the driver misunderstands that the driving force transmission system is connected and starts the route bus 10 even though the driving force transmission system is not connected. Therefore, even when the vehicle is stopped on a slope, the vehicle can be prevented from sliding down.

  Further, when the route bus 10 is stopped, the parking door 28 is opened when the inner door 12 is opened (step 7) and the driving force transmission system is shut off (step 10) (step 11). Even if one driver forgets to step on the foot brake 20, the parking bus 28 can reliably stop the route bus 10.

  In the present embodiment, the parking brake 28 is operated in step 11 and the parking brake 28 is released in step 15. In particular, even if the parking brake 28 is not operated, the safety of passengers and the like is particularly important. The route bus 10 can be safely operated.

  According to the present invention, when the vehicle starts, it is possible to alert the driver that the driving force transmission system is not connected and start the vehicle safely.
