Abstract

There is a demand for enhancement of operability when a change of combination of rollers of a chassis dynamometer and the dynamometer is set depending upon a vehicle type of a test vehicle. A status indicating function block that indicates an equipment construction is disposed in a main menu display area that is provided on a console. With this arrangement, a current test status can be recognized. Further, a vehicle type selection window calling function block is disposed in a mode setting function button group in the main menu display area. A vehicle type selection window called by the vehicle type selection window calling function block includes a roller selection section to select rollers corresponding to the test vehicle, a setting display section that indicates a current setting equipment construction, and a setting display section that indicates a setting equipment construction during change of the setting.

First claim

The invention claimed is:

1. A chassis dynamometer system comprising:
a controller configured to control rollers through inverters upon testing a test vehicle loaded on the rollers, and
an operation display device comprising:
an operation window in which setting of the controller is carried out, the operation window comprising a status indicating function block comprising a first icon and a second icon, wherein the first icon indicates a use or a non-use of a front roller and the second icon indicates a use or a non-use of a rear roller as a setting status of the chassis dynamometer system,
wherein the operation window further comprises a main menu display area and a submenu display area, wherein the main menu display area comprises a window that indicates an operation lock function block, a mode setting function button group and an on/off changeover function button group, and the status indicating function block,
wherein the mode setting function button group comprises a vehicle type selection window calling function block that calls a vehicle type selection window displayed in the submenu display area, the vehicle type selection window comprising a vehicle type selection section to select a vehicle type corresponding to the test vehicle and a roller selection section to select the rollers corresponding to the test vehicle, a current setting display section that indicates a current setting status of the rollers, and a setting changing display section that indicates a new setting status of the rollers, and
wherein a user selects the vehicle type and the rollers corresponding to the test vehicle using the vehicle type selection section and the roller selection section, respectively, and the status indicating function block and the setting changing display section are updated, based on the user's selection, to display the new setting status of the rollers.

2. The chassis dynamometer system as claimed in claim 1 , wherein the status indicating function block comprises at least one of an indicator section that indicates an on/off status of a cooling fan and a speed indicator section that indicates a vehicle speed of the test vehicle.

3. The chassis dynamometer system as claimed in claim 1 , wherein the vehicle type selection window comprises a front-wheel drive display section, a rear-wheel drive display section and a four-wheel drive display section which indicate a front-wheel drive, a rear-wheel drive and a four-wheel drive as drive systems of the test vehicle, respectively, and wherein the front-wheel drive display section comprises a front-wheel drive roller selection section and a front-wheel drive-and-rear-wheel follow-up roller selection section which are disposed adjacent to each other, the rear-wheel drive display section comprises a rear-wheel drive roller selection section and a rear-wheel drive-and-front-wheel follow-up roller selection section which are disposed adjacent to each other, and the four-wheel drive display section comprises a fulltime four-wheel drive roller selection section and a rigid four-wheel drive roller selection section which are disposed adjacent to each other.
