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.

Claims

1. An operation display device of a chassis dynamometer system, the chassis dynamometer system including a controller that controls rollers through inverters upon testing a test vehicle loaded on the rollers, the 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 that indicates use/non-use of front and rear rollers as a setting status of the chassis dynamometer system.

2. The operation display device of a 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 operation display device of a chassis dynamometer system as claimed in claim 1, wherein the operation window is constituted of a main menu display area and a submenu display area, the main menu display area comprising a window that indicates an operation lock function block, a mode setting function button group and an on/off changeover function button group in addition to the status indicating function block.

4. The operation display device of a chassis dynamometer system as claimed in claim 3, wherein the mode setting function button group comprises a vehicle type selection window calling function block that calls a vehicle type selection window, the vehicle type selection window as called by the vehicle type selection window calling function block comprising a roller selection section to select the rollers corresponding to the test vehicle, a current setting display section that indicates a setting status of the rollers that are currently used, and a setting changing display section that indicates a setting changing status in which the setting status of the rollers previously used is in the course of change to a setting status of the rollers corresponding to a vehicle type of the test vehicle, the roller selection section, the current setting display section and the setting changing display section being disposed on a same window.

5. The operation display device of a chassis dynamometer system as claimed in claim 3, wherein the mode setting function button group comprises a vehicle type selection window calling function block that calls a vehicle type selection window, the vehicle type selection window as called by the vehicle type selection window calling function block comprising 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, the front-wheel drive display section comprising 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 comprising 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 comprising a fulltime four-wheel drive roller selection section and a rigid four-wheel drive roller selection section which are disposed adjacent to each other.
