Description

  The present invention relates to a display method of a driver's aid display device and a method of creating a travel speed pattern in a driver's aid device used for performance evaluation of an automobile performed on a chassis dynamo.

  Chassis dynamometers used for vehicle performance tests (running resistance, climbing board, vehicle weight, etc.) can easily perform experiments equivalent to running on real roads indoors with high reproducibility, so fuel consumption measurement It is widely used for tests such as tests, exhaust gas characteristics tests or general high-speed, acceleration / deceleration or durability tests.

  In the vehicle running test using the chassis dynamometer, the vehicle performance evaluation is performed on a monitor (driver aid display device) such as a CRT display device so that the driver can perform a reproducible operation. The driving pattern (traveling speed pattern) is displayed.

  The driver's aid displays what speed the vehicle under test is driven, and is exemplified by a graph (running speed pattern) displaying the speed of the vehicle under test with respect to the test time. Specific examples of the traveling speed pattern include driving patterns such as “10/15 mode” and “US06 mode” (for example, Patent Documents 1 and 2). .

  The vehicle performance is evaluated by the driver driving the vehicle under test on the chassis dynamometer so as to follow the traveling speed pattern.

  Thus, when driving the vehicle under test so as to follow the travel speed pattern, the driver of the vehicle under test must be careful mainly to always match the travel speed pattern and the speed of the vehicle under test. .

  Therefore, the vehicle performance can be checked so that the driver of the vehicle under test can check other information (for example, throttle opening, road gradient, etc.) while checking the traveling speed pattern information and the actual vehicle speed of the vehicle under test. Information necessary for the test is displayed on the driver aid display device (for example, Patent Documents 1 to 5).

  Currently, vehicle performance evaluation methods are diversified, and it is required that not only the exhaust gas test as described above but also a running test on an actual road is reproduced on a chassis dynamometer.

  When reproducing a running test on an actual road, road surface data is collected by actually running on the road on which the running test is performed (for example, Patent Documents 6 and 7), and a running speed pattern is determined based on the collected data. Created and displayed on the driver's aid display. The road surface data is collected a plurality of times, and the average is taken to improve the accuracy of the traveling speed pattern.

Japanese Patent Laid-Open No. 8-170938 JP 11-160203 A Japanese Patent Laid-Open No. 11-37902 JP-A-11-153519 JP-A-11-160204 JP-A-63-215936 JP-A-8-304237

  However, even with the same speed command, the accelerator operation differs depending on the road surface information (gradient information, curve information, etc.), so the driver of the vehicle under test receives the road surface information while observing the travel speed pattern. It was necessary to convey it in an easy-to-understand (easy to recognize) way to the driver of the test vehicle.

  That is, even in the prior art, there is a driver aid device that displays a traveling speed pattern and gradient information (for example, Patent Document 1), but the driver of the vehicle under test operates following the traveling speed pattern. He had to drive while watching the speed pattern.

  In other words, even if the driver's aid device displays the driving speed pattern and gradient information on the same screen, if the position where the driving speed pattern is displayed and the position where the gradient information is displayed are different, watch the driving speed pattern. In this state, the gradient information (or curve information etc.) cannot be confirmed. Therefore, there is a need for a display method that allows the driver of the vehicle under test to recognize gradient information (or curve information) while paying attention to the traveling speed pattern.

  In addition, a method for acquiring travel data when performing a travel performance test on an actual road that is not determined by the standard is performed based on the travel data by traveling a plurality of times on the road on which the performance test is actually performed. The operation of actually traveling on the road where the performance test is performed and collecting data a plurality of times is time-consuming, and it is necessary to collect data again when changing the road where the performance test is performed. In addition, when an environmental test is performed on a cold or highland road, the time and effort required to actually run on the road are considerable. Furthermore, it has been difficult to improve the accuracy of the traveling speed pattern by the conventional method of collecting the data on the road for performing the performance test a plurality of times and taking the average. This is because, even when traveling on the same road, it is difficult to obtain reproducible data due to traffic jams, weather effects, and the like.

  Accordingly, the present invention provides a driver aid apparatus that presents information necessary for a driver aid display device in an easy-to-understand manner so that the driver of the vehicle under test can follow the traveling speed pattern, and a highly accurate traveling test pattern. It aims at providing the driver's aid display device which can produce.

  A driver aid apparatus according to the present invention that achieves the above object is provided with display control means for displaying a traveling speed pattern, which is a driving pattern for performing performance evaluation of a test vehicle in a chassis dynamometer, on a display device. In the apparatus, the display control means causes a marker indicating the inclination of the vehicle to be displayed in an inclined manner in an area for displaying the traveling speed pattern on the screen of the display device based on slope information of a road surface on which a traveling test is performed. It is said.

  In addition, the driver aid apparatus of the present invention that achieves the above object is a driver comprising display control means for displaying on a display device a traveling speed pattern that is a driving pattern for performing performance evaluation of a test vehicle in a chassis dynamometer. In the aid device, the display control means displays the curve information of the road surface on which the running test is performed in a region where the running speed pattern is displayed on the screen of the display device, and the display is performed according to the angle of the curve. It is characterized by changing the color of the curve information.

  Furthermore, the driver aid apparatus of the present invention that achieves the above object is a driver comprising display control means for displaying a traveling speed pattern, which is a driving pattern for performing performance evaluation of a test vehicle in a chassis dynamometer, on a display device. In the aid apparatus, the display control means displays terrain information based on the altitude of the road surface on which the running test is performed in a region where the running speed pattern is displayed on the screen of the display device.

  The display control means and the traveling speed pattern creation means of the driver aid apparatus described above can be realized by a computer and a program, and the program can be recorded on a recording medium and provided through a network. Examples of the program include a program for causing a computer to function as display control means and traveling speed pattern creation means of a driver aid device.

  According to the above invention, the accuracy of vehicle performance evaluation by the chassis dynamometer is improved.

  A chassis dynamometer apparatus provided with a driver aid apparatus according to a first embodiment of the present invention will be described in detail with reference to FIGS.

  As shown in FIG. 1, a chassis dynamometer device 1 according to an embodiment of the present invention includes a chassis dynamometer 3 on which driving wheels of a vehicle under test 6 are mounted, a driver aid device 5, and a driver aid display device 4. Consists of

  The chassis dynamometer 3 is controlled by the chassis dynamo control computer device 21 via the operation measurement board 22 and the dynamo control board 23.

  The computer device 21 for chassis dynamo control calculates the running resistance to be applied to the vehicle under test 6 based on the test schedule information input from the driver aid device 5, the vehicle speed acquired from the vehicle under test 6, and the like. The torque of the dynamometer 3 for simulating the calculated running resistance is calculated as the running resistance torque.

  Further, the chassis dynamo control computer device 21 estimates the acceleration in the running that the vehicle under test 6 is simulating, and the chassis dynamometer for simulating the inertia of the vehicle under test 6 at the estimated acceleration. 3 is calculated as the inertia torque.

  In the operation measurement panel 22, the calculated running resistance torque and inertia torque are added, and this control signal is output to the dynamo control panel 23. The dynamo control panel 23 controls the chassis dynamometer 3 based on this control signal.

  The driver's aid apparatus 5 includes a display control unit 51 and a traveling speed pattern creation unit 52.

  The traveling speed pattern creating means 52 receives data of the vehicle 9 actually traveling on the road where the traveling test is performed, and a traveling speed pattern is created based on this data.

  As shown in FIG. 1, when a vehicle 9 on which a GPS (Global Positioning System) receiver 8 is mounted runs on a road where a running test is performed and travel data is acquired, a travel speed pattern is obtained as shown in FIG. Information (for example, latitude, longitude, altitude, time) received by the GPS receiver 8 is input to the creation unit 52. Therefore, the traveling speed pattern can be created using the data collected by the vehicle 9 actually traveling on the road where the traveling speed pattern is performed and the information received by the GPS receiver 8. Based on the information received by the GPS receiver 8, the traveling speed pattern can be corrected, and a more accurate traveling speed test can be performed.

  For example, as shown in FIG. 3, since the position of the vehicle 9 and the vehicle speed information at the position can be obtained only from the information acquired by the GPS receiver 8, the vehicle 9 on the road where the running test is performed is obtained. The travel distance can be obtained only from the information received by the GPS receiver 8. Therefore, it is possible to easily create a travel speed pattern with the horizontal axis of the travel speed pattern as the travel distance and a travel speed pattern with the horizontal axis of the travel speed pattern as the time.

  The display control means 51 causes the driver's aid display device 4 to display the traveling speed pattern created by the traveling speed pattern creating means 52. Further, the display control means 51 displays information (gradient information, curve information, etc.) necessary for the driver of the vehicle under test 6 to drive the vehicle under test 6 following the travel speed pattern. To display.

  The functions of the display control means 51 and the traveling speed pattern creation means 52 can be realized by a computer and a program. The program can be stored in a known recording medium or provided through a network (the same applies to the second embodiment).

  The driver's aid display device 4 is a CRT display device or the like, and displays a traveling speed pattern output from the driver's aid device 5. Then, the driver of the vehicle under test 6 drives the vehicle under test 6 on the chassis dynamo 3 so as to follow the travel speed pattern while checking the travel speed pattern.

  4 to 7 show display examples of the driver aid display device 4.

  In the driver's aid display device 4, a traveling speed pattern 12 is displayed on the main screen 11. The driver of the vehicle under test 6 operates so that the vehicle speed of the vehicle under test 6 follows the traveling speed pattern 12. Further, the driver's aid display device 4 includes a sub-screen 11a for displaying the entire process of running test, analog speed information 17, analog gradient information 18, driving time 19 of the vehicle under test, travel distance of the vehicle under test. 20 etc. may be displayed. The analog speed information 17 may display the current vehicle speed and the target vehicle speed.

  As shown in FIG. 4, the display control unit 51 may cause the main screen 11 of the driver's aid display device 4 to display terrain information 13 and gradient information 16 in addition to the traveling speed pattern 12. Further, a reference line 15 is displayed on the main screen 11 as a line indicating the current position of the vehicle under test 6.

  The terrain information 13 displays information related to the altitude of the road surface on which the running test is performed. The topographic information 13 is displayed based on altitude information obtained from GPS, for example.

  The gradient information 16 indicates information on the gradient (angle) of the road surface on which the driving test is performed. If the gradient information 16 is displayed above the gradient 0 reference line 16b, the gradient information 16 is an upward gradient, and is displayed below the gradient 0 reference line 16b. Indicates a downward slope.

  FIG. 5 is an enlarged view of the sub-screen 11a. The travel speed pattern 12a for the entire travel speed test, the topographic information 13a for the entire travel, the gradient information 16a for the entire travel, the gradient 0 reference line 16c, and the vehicle under test 6 are shown. A reference line 15a indicating the current position is displayed.

  In the present embodiment, as shown in FIG. 4, the vertical axis of the traveling speed pattern 12 displayed on the main screen 11 is the vehicle speed, and the horizontal axis is the traveling distance.

  In the exhaust gas operation mode such as the US06 mode, the horizontal axis of the travel speed pattern 12 is time. That is, when performing a speed test determined by the standard, it is required to drive the vehicle under test 6 in accordance with a speed command for maintaining the vehicle speed for a certain time or a speed command for changing the vehicle speed for a certain time. In other words, when the running test is performed, the scroll speed of the screen is constant even if the vehicle speed changes, and the driver of the vehicle under test 6 cannot grasp the driving state in a realistic manner.

  On the other hand, when a test is performed in which the horizontal axis of the travel speed pattern is a distance and the vehicle travels in a simulated manner, the speed at which the screen scrolls changes according to the vehicle speed. Can be reproduced realistically. Furthermore, by setting the horizontal axis of the travel speed pattern 12 as the travel distance, the driver of the vehicle under test 6 can be informed of the route information for the travel test and the distance for the travel test.

  Further, since the actual road travel data, which is data for creating the travel speed pattern 12, is vehicle speed-distance data, there is an advantage that the actual road travel data can be used as it is by setting the horizontal axis as the travel distance. . Therefore, it is possible to omit the operation of converting the vehicle speed-distance into the vehicle speed-time, which has been performed when the travel speed pattern 12 is produced.

  If the display method in which the horizontal axis of the travel speed pattern is the test time and the display method in which the horizontal axis of the travel speed pattern is the distance traveled by the vehicle under test 6 can be switched as in the prior art, the vehicle under test 6 Drivers can select a display method that is easy to drive.

  As described above, when the horizontal axis of the traveling speed pattern 12 is displayed as the distance traveled by the vehicle under test 6, the traveling speed of the traveling speed pattern 12 changes according to the speed of the vehicle under test 6. Therefore, it may be easier for the driver of the vehicle under test 6 to grasp the traveling state when the reference line 15 is moved and displayed.

  The reference line 15 may be displayed on the screen 11 so as to be fixed or movable. That is, conventionally, the reference line 15 is fixed, and the traveling speed test is performed by scrolling the screen on which the traveling speed pattern 12 is displayed. The line 15 may be moved and displayed. At this time, the screen may be switched before the reference line 15 goes to the right end of the screen, and a state in which the reference line 15 is moved to the left end may be displayed.

  In the example shown in FIG. 4, a marker 14 indicating the state of the vehicle is displayed at the intersection of the reference line 15 and the terrain information 13 on the main screen 11. The marker 14 may display an object that can be recognized as a vehicle, such as a vehicle silhouette or a vehicle picture, or an arrow that represents the state of the vehicle.

  The marker 14 is displayed at either the intersection of the reference line 15 indicating the position of the test vehicle 6 displayed in the area for displaying the traveling speed pattern and the traveling speed pattern 12 or the intersection of the reference line 15 and the terrain information 13. do it.

  FIGS. 6A and 6B are examples of enlarged views of the marker 14 display area of the main screen 11.

  As shown in FIG. 6A, the marker 14 is displayed at the current position of the vehicle under test on the terrain information 13. Therefore, the driver of the vehicle under test 6 can easily confirm the marker 14 while gazing at the traveling speed pattern 12. The marker 14 may be displayed at the current position of the vehicle under test on the traveling speed pattern 12, that is, at the intersection of the reference line 15 and the traveling speed pattern 12.

Further, as shown in FIG. 6B, when the marker 14 is displayed in an inclination according to the slope of the road surface to be tested, the driver of the vehicle under test 6 is displayed on the main screen 11 due to the inclination of the marker 14. Gradient information can be grasped while gazing at the traveling speed pattern 12. At this time, the color is displayed in different colors depending on whether the road surface is up or down, and the shade of the color is changed according to the angle of the road surface gradient. If it is changed and displayed, more detailed gradient information can be transmitted to the driver of the vehicle under test 6. For example, it is preferable to display red as the up and blue as the down, and to increase the darkness of red or blue as the gradient angle increases. However, the display method is not limited to this example, and the color may be set to an easily understandable color as appropriate. Furthermore, when the color of the marker 14 is displayed translucently, it does not hinder the driver of the vehicle under test 6 from driving following the traveling speed pattern 12.

  FIG. 7 is an enlarged view of the display area of the travel route 27 showing the planar travel locus of the road surface on which the travel test is performed, displayed in the display example of FIG.

  By displaying the traveling route 27 of the road surface on which the traveling test is performed, the driver under test 6 can instantly understand the route for performing the traveling test and the remaining distance of the traveling test. When the driving route 27 on the road surface on which the driving test is performed is scrolled with the progress of the driving test or when the driving route after the driving test is changed in color, the driver of the vehicle under test 6 determines the degree of progress of the driving test. Can understand.

  Next, a chassis dynamometer device including a driver aid device according to a second embodiment of the present invention will be described in detail with reference to FIGS.

  In the chassis dynamometer device 2 according to the second embodiment of the present invention shown in FIG. 8, the same components as those of the chassis dynamometer device 1 according to the first embodiment shown in FIG. Detailed description is omitted.

  In the dynamometer device 2 according to the second embodiment, the driver aid device 5 includes a traveling speed pattern creating unit 53 that creates a traveling speed pattern based on the map data 10. The travel speed pattern creating means 53 has a travel simulation function (not shown).

  The traveling speed pattern creating unit 53 creates a traveling speed pattern based on the map data 10. In this case, the road surface on which the running test is performed may be run with an actual vehicle, and a running speed pattern may be created using the running data and the map data 10.

  That is, according to the driver aid apparatus according to the second embodiment, as shown in FIG. 9, the traveling speed pattern creating means 53 creates a traveling speed pattern based on the map data 10, so that a traveling test is performed. A traveling speed pattern can be obtained without traveling on the road surface with an actual vehicle. For example, when creating a traveling speed pattern, the acceleration method, deceleration method, and curve speed of the vehicle under test are set in the traveling simulation function with the legal speed limit set on the road surface where the traveling test is performed as the upper limit. Thus, a traveling speed pattern of an arbitrary road surface on the map can be created. The map data 10 does not include at least data for calculating the distance (for example, information on latitude and longitude) and data for calculating the gradient of the road surface (for example, information on altitude). Must not.

  Further, even when traveling on a road surface to be tested with a real vehicle equipped with a GPS receiver 8 as in the first embodiment, a more accurate traveling speed pattern is created by adding information from the map data 10 It is possible to reduce the number of times the vehicle is driven.

  In the chassis dynamometer device 2 according to the second embodiment, a display example of a running speed pattern on the driver aid display device 4 is shown in FIGS.

  In the display examples of FIGS. 10 and 11, the same reference numerals are assigned to the same display examples as the driver aid display device 4 of the chassis dynamometer device 1 according to the first embodiment shown in FIG. Detailed description thereof will be omitted.

  In the display example of FIG. 10, a curve band 28 is displayed on the main screen 11 as curve information of a road surface on which a running test is performed.

  The curve band 28 may be displayed by a method of changing the background color of the main screen 11 according to the angle of the curve. For example, if a color according to the angle of the curve is displayed, such as red for a steep curve and green for a gentle curve, detailed curve information can be obtained with the driver of the vehicle under test 6 gazing at the traveling speed pattern 12. Can be confirmed.

  In the display example of FIG. 10, the gradient information 16a of the entire running test is displayed on the sub screen 11a, and the analog gradient information 18 is also displayed.

  In addition, the altitude information 24, the atmospheric pressure information 25, the air temperature information 26, and a road route 27 on which the road test is performed are displayed.

  The altitude information 24 may be displayed based on the map data 10. Note that the temperature and pressure may be changed based on the altitude information 24.

  The temperature information 26 includes displaying the outside temperature of the vehicle that actually traveled on the road where the driving test is performed, or inputting the local temperature. The temperature information 26 can be set as appropriate during the test running of the vehicle under test 6.

  In the display example of FIG. 11, a travel route 27 on the road surface on which the travel test is performed is displayed, and a map (road information) on which the travel test is performed is displayed on the travel route 27. Therefore, the driver of the vehicle under test 6 can confirm the place where the running test is performed and how much the running test has been performed.

  This map is a part of the map 10 used when the traveling speed patterns 12 and 12a shown in FIG. 5 are created, and includes gradient information and curve information. Therefore, the gradient information and curve information of the map 10 may be synchronized with the main screen 11 and the terrain information 13 and 13a and the gradient information 16 and 16a of the sub screen 11a.

  In addition, in the display example of FIG. 11, driving force, intake pressure, and analog gradient information 18 are displayed.

  As described above, according to the driver aid apparatus according to the present invention, it is possible to recognize the curve information and the gradient information of the road surface to be tested while the driver of the vehicle under test is gazing at the traveling speed pattern.

  Even if the speed command is the same, the accelerator operation is different when the gradient is up or down. Therefore, by making it easier for the driver of the vehicle under test to recognize the curve information and the gradient information while looking at the traveling speed pattern, it is possible to perform driving along the traveling speed pattern.

  Then, by displaying a map of the road surface on which the running test is performed, it is possible to accurately convey the overall image of the running test and the progress of the running test.

  Note that the curve information, the gradient information, the map, and the like of the driver aid apparatus according to the present invention may be displayed as necessary, or may be displayed in combination.

  According to the driver aid apparatus according to the present invention, the travel speed pattern is created based on the map data (including the height information), so that the data on the road travels on the road on which the travel test is performed with the actual vehicle. It is possible to create a traveling speed pattern on an arbitrary road surface without collecting the vehicle.

  In addition, even when driving the actual vehicle on the road where the driving test is performed and creating a driving speed pattern, the driving data of the actual vehicle is supplemented with map data and GPS data, so that the driving test is repeated several times in order to obtain an average. Although the vehicle was traveling on the road where the vehicle is operated, the number of times of traveling can be reduced.

  For example, by creating a traveling speed pattern using actual measurement data that has traveled once on a road on which a traveling test is performed, and map data that is not changed by the actual vehicle driver (or information acquired from GPS), The accuracy of the traveling speed pattern can be improved.

  In particular, when conducting environmental tests in highlands and cold regions, it is necessary to carry a vehicle to create a running speed pattern in highlands and cold regions (for example, Kilimanjaro and South America) far from the city center, and in highlands and cold regions. The effort to perform a test run many times and create a running speed pattern is considerable. Therefore, according to the driver aid apparatus according to the present invention, the traveling speed pattern can be easily generated from the map data, so that the convenience of testing the vehicle under test is improved.

  That is, according to the driver aid apparatus according to the present invention, it is possible to easily display information for the driver of the vehicle under test to drive following the traveling speed pattern.

  Further, when creating a travel speed pattern on the road where the travel test is performed, an error caused by each driver traveling on the road where the travel test is performed can be corrected based on the map data and the GPS data.

  Therefore, the accuracy of vehicle performance evaluation by the chassis dynamometer can be improved. Note that it is preferable that the horizontal axis of the travel speed pattern is the travel distance because the travel test can be reproduced, but the travel speed pattern may be displayed as time as in the prior art.
