DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle operation mode display device used for performing a mode operation test on a vehicle such as an automobile.

[0002]

2. Description of the Related Art For example, a mode driving test of an automobile is generally performed as follows. That is, as shown in FIG. 3, a test driver (not shown) sitting in the driver's seat of an automobile 4 in which, for example, the rear wheel 3 is held by the roller 2 of the chassis dynamometer 1 is operated by a remote control switch 5.
To control the start signal and a data processing device 6 such as a computer having a function of controlling the entire test apparatus.
Send to As a result, the data processing device 6
A start signal is sent to a vehicle operation mode display device (also referred to as a driver's aid) 7 provided at an appropriate position in front of the vehicle and data collection is started. Then, the test driver performs driving to match the speed indicated by the running speed pattern 8 displayed on the display screen 7A of the vehicle operation mode display device 7, and performs analysis based on data collected at that time. .

In FIG. 3, reference numeral 9 denotes a pointer indicating the current vehicle speed, 10 denotes a dynamo controller for controlling the chassis dynamometer 1 in accordance with a command from the data processing device 6, and 11 denotes exhaust gas discharged from the engine of the automobile 4. The output is input to the data processing device 6.

[0004]

By the way, data relating to the vehicle such as speed, engine speed, mileage, engine boost pressure (manifold negative pressure), and atmospheric pressure, ambient temperature, humidity, etc. during the test. For so-called general-purpose data such as data on test conditions,
Each is measured by various sensors (not shown) provided in the automobile 4 and measuring instruments such as a pressure gauge, a thermometer, and a hygrometer.
The data is input to the data processing device 6 through the data processing device 3, but conventionally, the data is not displayed on the vehicle operation mode display device 7, but a plurality of display units 14 provided separately in the vicinity of the data processing device 6 are provided.
a to 14d (only four are shown in the illustrated example) are appropriately displayed on the data display device 14.

However, the display units 14a to 14d
It is necessary to attach an analog / digital meter to a panel, and the general-purpose data is
Each user may be different, and the meter must be replaced to display necessary general-purpose data, which is inconvenient for the user.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide a vehicle operation mode display device capable of displaying general-purpose data in a reasonable and convenient manner. It is in.

[0007]

To achieve the above object, the present invention relates to a vehicle operation mode display device for displaying a traveling speed pattern of mode driving on a display screen. the provided a display unit for analog and / or digitally displayed, and to display the general data graphically by the table <br/> radical 113, further, the display unit, with the various data items
And the display screen
Display items and tables of traveling speed patterns and general-purpose data in
As for the form of presentation, the program in the computer
Therefore, it can be set arbitrarily .

According to the above configuration, data processed by a data processing device such as a computer is simply displayed on a screen by software. Therefore, unlike the related art, there is no need to provide an analog / digital meter, and a necessary general purpose device is provided. The data can be displayed reasonably and easily and the hardware cost for the display can be reduced. Further, since the user can appropriately set the type and area of the general-purpose data to be displayed, the general-purpose data required for each user can be selected, and a screen that is easy to see for each user can be realized.

[0009]

Embodiments of the present invention will be described with reference to the drawings. 1 and 2 show an embodiment of the present invention. First, in FIG. 2, reference numeral 15 denotes a vehicle operation mode display device of the present invention. The vehicle operation mode display device 15 is greatly different from the conventional vehicle operation mode display device 7 in that general-purpose data can be graphically displayed on the display screen 16 in addition to the traveling speed pattern 8.

The vehicle operation mode display device 15 is controlled by a signal from a computer 6 as a data processing device. As shown in FIG. An area 17 for displaying the speed pattern 8 and an area 18 for displaying the general-purpose data D are provided. These two areas 17 and 18 are not fixed, and the user can appropriately set the arrangement relationship and size (area) thereof and display items (contents) in them. Are rewritably stored in a storage unit such as a RAM in the computer 6. Then, the stored contents are appropriately set by a program in the computer 6.

In this embodiment, the area 1
7 includes, as display contents, a WOT (Wide Open Throttle) in addition to the traveling speed pattern 8.
And a message 20 to the driver can be displayed.

An area 18 for displaying general-purpose data D
Is divided into, for example, four 18A to 18D so that various data items can be displayed.
Include Temp (room temperature), RH (humidity), Boost
(Boost pressure), Ref. Pres (reference pressure), Eng
a display unit for digitally displaying data D such as ine Rev (engine speed) is provided.
In the section 18B, Rest time (remaining time),
A display unit is provided for digitally displaying data D obtained by calculation such as Total Error Time (total time traveled out of the pattern) and Distance (travel distance). The third section 18C includes:
Total Time (total time), Phase Time
e (Face time) display unit for digitally displaying each time data D, such as are formed, the fourth compartment 18
D, the display unit for each analog displaying the data D, such as boost pressure and the engine speed is formed.

The display screen 16 of the vehicle operation mode display device 15 uses an LCD (Liquid Crystal Display), but is not limited to this. Even if it is a CRT display, an ELD (Electroluminescence) is used. Display).

In the vehicle operation mode display device 15, a screen 16 for displaying the traveling speed pattern 8
Since various general-purpose data D required for the test driver can be displayed in digital or analog form,
Unlike the conventional one, in addition to the vehicle operation mode display device 15,
There is no need to provide an analog / digital meter, and necessary general-purpose data can be displayed reasonably and easily.

The display items and the display form of the traveling speed pattern 8 and the general-purpose data D on the display screen 16 can be arbitrarily set in accordance with a program in the computer 6, so that the display items and the display items are optimally used by the user. The display mode can be set, the usability is greatly improved as compared with the related art, only necessary items can be displayed without waste, and the hardware cost for display can be reduced.

[0016]

As described above, according to the present invention, the traveling speed pattern and the general-purpose data can be simultaneously displayed on the same screen in parallel, so that it is not necessary to provide an analog / digital meter. The necessary general-purpose data can be displayed reasonably and easily,
Hardware cost for display can be reduced. Then, the data necessary for the test driver can be easily seen, and the fatigue can be reduced.
