[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle operation mode display device used when a mode operation test of a vehicle such as an automobile is performed.
[0002]
[Prior 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 the automobile 4 with the rear wheel 3 held by the roller 2 of the chassis dynamometer 1 operates the remote control switch 5 to start. The signal is sent to a data processing device 6 such as a computer having a function of controlling the entire test apparatus. As a result, the data processing device 6 sends a start signal to a vehicle operation mode display device (also referred to as a driver aid) 7 provided at an appropriate position in front of the automobile 4 and starts collecting data. Then, the test driver operates to match the speed indicated by the traveling speed pattern 8 displayed on the display screen 7A of the vehicle operation mode display device 7, and analyzes based on the data collected at that time. .
[0003]
In FIG. 3, 9 is a marker representing the current vehicle speed, 11 is a dynamo controller that controls the chassis dynamometer 1 in accordance with a command from the data processing device 6, and 12 analyzes exhaust gas discharged from the engine of the automobile 4. The output of the exhaust gas analyzer is input to the data processor 6.
[0004]
Also, input data related to the vehicle 4 such as speed, engine speed, travel distance, engine boost pressure (manifold negative pressure) in the vehicle 4 and input data related to test conditions such as atmospheric pressure, ambient temperature, and humidity at the time of the test. The general-purpose data 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 general-purpose data is sent via the interface 13. Although it is input to the data processing device 6, conventionally, it is not displayed on the vehicle operation mode display device 7, but a plurality of display units 14 a to 14 d (separately four in the illustrated example) provided in the vicinity thereof. The data is displayed on the data display device 14 having (not shown) as appropriate.
[0005]
[Problems to be solved by the invention]
However, in recent years in the United States WOT on the content of the mode operation test of the vehicle (Wide Open
It is regulated by law (for example, US06 mode) to include control of “Throttle” (value indicating throttle opening), and the conventional apparatus shown in FIG. 3 has nothing to display WOT.
[0006]
In the conventional configuration, the general-purpose data input to the data processing device 6 is not displayed on the vehicle operation mode display device 7, but a plurality of displays 14a to 14d (four in the illustrated example) provided separately in the vicinity thereof. However, even if the WOT is input to the data processing device 6, it is necessary to separately attach an analog / digital meter indicating the WOT. Alternatively, it is necessary to display the WOT to one of a plurality of display portions of the existing data display device 14.
[0007]
In addition, it is difficult to perform a test while constantly looking at the WOT meter or the data display device 14 at a position distant from the vehicle operation mode display device 7, and when the test driver notices, it runs for a long time with the WOT exceeding the specified value. There was also. In other words, with a simple analog / digital meter, the test driver had to determine whether the WOT exceeded the specified value. Furthermore, it was difficult for the test driver to recognize the cumulative total of overtime when the WOT exceeded the specified value.
[0008]
In addition, depending on the vehicle type of the automobile 4 to be tested, when the vehicle is driven according to the prescribed travel speed pattern, the total time that the WOT exceeds the prescribed value may exceed the prescribed time. In order to avoid this, it has become necessary to lighten the load applied to the automobile 4 by the chassis dynamometer 1. In this case, simply displaying the WOT with an analog / digital meter may cause an overspeed because the moment when the load is reduced is not transmitted to the test driver.
[0009]
The present invention has been made in consideration of the above-mentioned matters, and the object of the present invention is to comply with the provisions of WOT by displaying the display contents of the vehicle operation mode display device rationally and conveniently. Another object of the present invention is to provide a vehicle driving mode display device that allows a test driver to easily and accurately perform a mode driving test.
[0010]
[Means for Solving the Problems]
To achieve the above object, the present invention includes a display unit for displaying the general data from the data processing device, and a display unit for displaying a marker indicating the traveling speed pattern and the current vehicle speed state of the mode operation In the vehicle operation mode display device having the same display screen , the display part for displaying the travel speed pattern and the marker, the part for displaying the numerical value of the throttle opening , and the cumulative excess time when the throttle opening exceeds the specified value Is provided with a display portion of a throttle opening having a portion for graphically displaying .
[0011]
According to the above arrangement, the display part for displaying a value indicative of throttle opening (WOT) on a display portion for that displays a marker indicating the traveling speed pattern and the current vehicle speed state of the mode operation on the display screen of the display device Therefore, the test driver can confirm the WOT without taking his eyes off the marker .
[0012]
In addition, since the display part of the throttle opening is provided with a display part that graphically displays the cumulative amount of excess time when the throttle opening exceeds the specified value, the amount of excess time when the throttle opening has exceeded the specified value is displayed. total also, test driver can be easily confirmed. Therefore, even if the load decreases when this excess time is likely to exceed the specified range, the test driver can predict this change and continue the mode driving test without overspeeding. Can do.
[0013]
Moreover, as of claim 2, when configured to change when the color of the portion that displays a numerical value of the throttle opening in the display portion of the throttle opening value of the throttle opening is greater than the specified value , test driver, not to transfer the eye to numeric display content of the throttle opening degree can be easily confirmed whether within the current throttle opening is defined. Therefore, fatigue of the test driver can be suppressed. Note that the setting of the color to be displayed is arbitrarily set by each user.
[0014]
Furthermore, as according to claim 3, when configured to part component for displaying the cumulative of the overtime in the display portion of the throttle opening is sequentially colored according to the length of the excess time, the excess time length Since the height can be determined by the color, the test driver can predict the time when the load becomes small without moving to the display portion indicating the excess time, and can perform the mode driving test more comfortably.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 and FIG. 2 show one embodiment of the present invention. First, in FIG. 2, 15 is 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, in addition to the travel speed pattern 8 and the marker 9 indicating the current state, the display screen 16 includes general-purpose data D and its contents. One of them is that the WOT data Dw can be displayed.
[0016]
The vehicle operation mode display device 15 is controlled by a signal from a computer 6 as a data processing device. A display screen 16 of the vehicle operation mode display device 15 has a traveling speed pattern 8 as shown in FIG. And a window (display unit) 17 for displaying the marker 9 and a window (display unit) 18 for displaying the general-purpose data D. These windows 17 and 18 are not fixed, and the user can appropriately set their arrangement relation and size (area) by dragging and dropping the windows, and display items (contents) displayed on the window 18. Can also be selected freely according to the detailed settings.
[0017]
In addition to the traveling speed pattern 8 and the marker 9 , the window 17 is provided with a window 19 for separately displaying the WOT displayed on the window 18 as a display content. The WOT window 19 has a portion 19a for displaying the WOT measurement number value Dw, and a portion 19b the WOT measurement numerical Dw is to graphically display the cumulative excess time exceeds the specified value.
[0018]
The background of the portion 19a displaying the WOT measurement numerical value Dw is displayed in red when the WOT exceeds, for example, a prescribed value of 85%. Further, in accordance with the excess time , the portion 19b for graphically displaying the accumulated excess time is lit in order from the left side. The display portion 19b of the excess time is composed of, for example, a 4-second portion a displayed in green from the left side, a 2-second portion b displayed in yellow, and a 2-second portion c displayed in red. For example, an overtime of 8 seconds can be displayed as a whole.
[0019]
The change in the color of the portion 19a that displays the WOT measurement value Dw is not limited to changing the background color to red, and the character that displays the WOT measurement value Dw may be red. In addition, if the color is conspicuous, it does not have to be red. Even in the case of monotone, it is possible to change the color depending on the brightness. Similarly, the colors of the respective parts a to c constituting the display part 19b for the excess time are not limited to green, yellow and red. Furthermore, the specified value of WOT can be set to other than 85%, and the excess time can be selected to other than 8 seconds. These settings are determined in accordance with the contents of the mode operation test to be executed.
[0020]
By disposing the display position of the WOT window 19 immediately below the side of the marker 9 (near) can be test driver confirms the contents of the WOT window 19 without removing the eye from marker 9. When performing a mode operation test without WOT control, if the WOT window 19 is not displayed, other display will not be disturbed.
[0021]
The window 18 for displaying the general-purpose data D is divided into, for example, five sections. That is, 18a is an input signal window for displaying general-purpose data D indicating the measurement value input from the automobile 4. For example, Boost Pressure, Engine Rev. (Engine rotation), Barometric pressure (atmospheric pressure), Dry Temp (dry bulb temperature), Wet Temp (wet bulb temperature), WOT, etc. are displayed as text. 18b is a test data window for displaying general-purpose data D representing values used for the test run calculated by the computer 6 based on these measured values, and 18c is a total time (total time) of them. It is a time window which displays the general-purpose data D showing time, such as Phase Time (phase time).
[0022]
Reference numeral 18d is a window that is arbitrarily selected from the general-purpose data D displayed in the windows 18a to 18c and displayed as an analog meter. Reference numeral 18e is a graph showing total traveling speed data indicating the speed change in all steps of the test traveling. a window to display the traveling data becomes non-traveling speed data already running already by displaying by color coding, and to understand the current travel position P instantaneously.
[0023]
Further, in this embodiment, the windows 18a to 18e displayed outside the window 17 may be displayed so as to overlap the window 17 as long as the size does not interfere with the traveling speed pattern 8. . In this case, when the overlapped windows 18a to 18e overlap the travel speed pattern 8, the windows 18a to 18e are automatically adjusted so as to be shifted.
[0024]
In the example described above, all of the window names and messages are written in English, but the present invention is not limited to this. That is, by storing the character string of the message to be displayed in a separate file, it is possible to display messages in various national languages just by switching the file. In this case, even if the user speaks any language such as English, Japanese, German, or French, the display screen 16 can be more easily seen by performing the display corresponding to the language.
[0025]
Since the various settings described above are all stored in the RAM in the computer 6, it is not necessary to reset each time the mode driving test of the automobile 4 is performed.
[0026]
The display screen 16 of the vehicle operation mode display device 15 is an LCD (liquid crystal display), but is not limited to this, and may be a CRT display or an ELD (display using electroluminescence). There may be.
[0027]
In the vehicle driving mode display device 15, the WOT measurement value Dw is displayed in the window 17 for displaying the traveling speed pattern 8 and the marker 9 on one display screen 16. The WOT can be confirmed without taking the eyes off. In particular, when the WOT exceeds the specified value, the color of the portion 19a for displaying this numerical value is changed, so that the test driver can easily check whether the WOT is within the specified range. it can.
[0028]
In addition, since the WOT is provided with a display unit worth 19b that total to graphic display of lasted overtime state that exceeds the specified value, sense of whether the test driver is over the extent to which the specified value in the running up to now Can know. Therefore, even when the load on the chassis dynamometer 1 is reduced by the computer 6 in order to prevent the WOT from exceeding the specified value beyond the range of the specified time (8 seconds in this example), the test driver Since it can be predicted that the load will be reduced by seeing that the display unit 19b for the excess time is all lit, it is possible to perform accurate speed control without causing overspeed.
[0029]
Especially, when the display unit fraction 19b of the cumulative over time are displayed in color-coded, without even looking at the display unit component 19b, it is possible to know the length of the excess time by color approximately vehicle driving mode display device so to speak so after receiving a warning is to adjust the load by 15, test driver is may not pay attention more than necessary on the display unit fraction 19b. That is, the fatigue of the test driver can be minimized.
[0030]
Since the display items and display forms of the traveling speed pattern 8 and the general-purpose data D on the display screen 16 can be arbitrarily set according to the program in the computer 6, the display items and display forms are optimally used by the user. It can be set, and usability is greatly improved as compared with the prior art. Only necessary items can be displayed without waste, and the hardware cost for display can be reduced.
[0031]
【The invention's effect】
As described above, according to the present invention, the traveling speed pattern, the marker, and the WOT can be simultaneously displayed in parallel in the same display section on one display screen, so that it can be displayed rationally and easily. can be test driver without removing your eyes from the marker, Rutotomoni it is possible to easily confirm the WOT, it is possible to reduce the cost because it does not require special hardware for display.
[0032]
In addition , the display part of the throttle opening that displays the cumulative total of the excess time exceeding the specified value is provided in the display part of the throttle opening, so the cumulative excess time that the WOT has exceeded the specified value is tested. The driver can easily check. Therefore, even if the excess time is likely to exceed the specified range and the load on the chassis dynamometer is reduced by a command from the data processing device, the test driver can predict this change, resulting in overspeed. The mode operation test can be accurately continued without any problem. Therefore, it is easy for the test driver to see the necessary data, and the fatigue can be reduced.
[0033]
Further, when configured to change when the color of the portion that displays a numerical value of the throttle opening in the display portion of the throttle opening value of the throttle opening is greater than the specified value, the display test driver WOT Needless to move the eye in part, because whether it is within the range of current WOT is a provision can be easily confirmed by the color, more user-friendly Ri is good, it is possible to suppress the fatigue of the driver.
[0034]
Further, when the display unit amount indicating the overtime is configured to be colored according to the length of the excess time, the test driver can know the moment when the load of the chassis dynamometer is reduced to sensory, The fatigue can be suppressed.
