Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a display device for a vehicle that uses a door for handling passengers, such as a general railway vehicle, a monorail, a track running vehicle such as a new transportation system, or a route bus. The present invention relates to a vehicle display device suitable for use in a vehicle for transporting passengers.

0002

[Prior Art] Conventionally, in a railway vehicle for transporting passengers, the doors for passengers to board and exit the train are operated by the conductor, and the door close signal is output only when all the doors are closed. has been done. When a door close signal is output, a lamp located in the driver's seat that indicates door close lights up, and a security lock that prevents power supply to the electric motor for starting operation is released. has been done.

[0003] While the railway vehicle is running, the driver of the vehicle must check the current time, the scheduled arrival time (scheduled arrival time or scheduled passing time) of the next destination station (stopping station or passing station), vehicle speed, and brake. Pressure (brake cylinder air pressure)
It is necessary to constantly recognize such information, that is, driving information. Additionally, when the train is stopped or running at extremely low speeds, the driver checks information other than the above travel information, such as the temperature of the train's air conditioner outlet, the opening/closing status of the doors, and the detailed timetable of the travel section. In some cases, a variety of verification information may be required to complete the process.

[0004] In order to enable the driver to perform comfortable driving operations, it is necessary to reduce the driver's effort and provide an ergonomically excellent driving environment. One possible way to improve the current driving environment is to adopt an MFD (multi-function display) that displays information such as a conventional speedometer, pressure gauge (Berke pressure gauge), ATS signal, etc. on a single display.

[0005]

[Problems to be Solved by the Invention] By the way, in a vehicle such as a railway vehicle that runs on the ground, the driver of the vehicle while it is running monitors the road ahead and receives accurate running information such as speed, time, and brake pressure. It is necessary to confirm. In such a moving vehicle, if information other than information directly necessary for driving such as the speed and time, that is, information that is unnecessary while driving is displayed on the MFD, the driver may check the necessary information. It becomes a hindrance to doing so. Therefore, when the vehicle is running, it is desirable to display only the driving information that the driver needs while driving. It is necessary for the driver to be able to confirm information (confirmation information) other than the travel information that requires confirmation when the vehicle is stopped or traveling at extremely low speeds. In this way, in a vehicle display device using an MFD that can display travel information and confirmation information, no matter what information is displayed while the vehicle is stopped, the travel information is automatically displayed when the vehicle starts traveling. If you make it appear,
There is no need for the driver to switch the display.

However, as described above, when the display is automatically switched by detecting the running drive source power switch or the running speed value at the start of running, for example, in a railway vehicle, the When performing an operation to release the brake and an operation to turn on power (operation to start acceleration), the display is not yet in the driving mode (no driving information is displayed). Therefore, until the brake pressure is lowered and the drive power source is turned on, the driver does not feel that the vehicle is in a running state through the display, which causes a great sense of discomfort to the driver.

[0007] In view of the above-mentioned circumstances, the present invention automatically displays running information on a display when a parked vehicle is ready to depart, thereby allowing the driver to perform an operation to start running without feeling any discomfort. The challenge is to do so.

[0008]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the display device for a vehicle of the present invention has a screen that displays driving information required by the driver while the vehicle is running, and a screen that displays travel information required by the driver while the vehicle is running. a display (MFD) that can display a screen that displays confirmation information that requires hand confirmation, a driving information display signal that causes the display (MFD) to display the driving information, and a confirmation information display that causes the confirmation information to be displayed. In a vehicle display device comprising a display signal output means (C) for outputting a signal and a door close signal output means for outputting a door close signal when all doors of the vehicle are closed, the display signal output means (C) ) is characterized by comprising means for outputting a travel information display signal when the door close signal is output.

Note that the display signal output means (C
) can be configured to output a travel information display signal whenever the door close signal is output. In addition, when the display signal output means (C) is set to display driving information with priority over display of other information when the door close signal is output (driving information priority display mode is set). The driving information display signal can also be configured to be output only when the vehicle is selected.

0010

[Operation] In the vehicle display device of the present invention having the above-mentioned configuration, when the display signal output means (C) is configured to output a travel information display signal whenever the door close signal is output. When all the doors of the vehicle are closed and the door close signal output means outputs the door close signal, the display signal output means (C) outputs the travel information display signal to the display (MDF). At this time, the display (MDF)
) displays driving information. Further, when the display signal output means (C) is set to display driving information with priority over other information when the door close signal is output (driving information priority display mode is selected). If the driving information display signal is configured to be output only when the door close signal is output (when the door close signal output means outputs the door close signal), if the travel information priority display mode is selected, the display will be displayed when the door close signal output means outputs the door close signal ( MDF) displays driving information. Therefore, when all the doors of the vehicle are closed and preparations are made for departure, the traveling information will be displayed on the display device (U).
At that time, the driver can naturally perform the operation to start driving the vehicle.
