Problems solved by technology

[0005] However, in the test device, in order to study whether the actual driving can be reproduced by the testing device, and to confirm whether the test can be performed by the testing device in a manner free from failure, it is necessary to compare the actual driving data obtained by the actual driving with the test device. The test result data obtained by the test, or the test result data obtained by the test, are compared, but because the data are output separately, data omission may occur in the middle of the comparison

Embodiment Construction

[0044] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

[0045] The vehicle test system 1 of the present embodiment includes: an actual driving data acquisition device 2 for acquiring actual driving data, the actual driving data being data of the internal and external states of the vehicle running on the road; and a test bed 3 for testing the vehicle and a part thereof; And the test management apparatus 4 sets the test conditions of the test stand 3, and performs test management. The vehicle test system 1 is an integrated system for newly developing a vehicle, correcting a malfunction of the vehicle, and the like.

[0046] Each part is explained.

[0047] The actual travel data acquisition device 2 is mounted on, for example, a vehicle. The actual driving data here refers to data representing the internal and external states of the vehicle, and the following states can be exemplified as the internal and exte...

Abstract

The present invention mainly intends to provide a vehicle test system and the like that can easily mutually compare actual running data and test result data obtained from a test apparatus, or pieces of test result data. The vehicle test system 1 includes: an actual running data acquisition apparatus 2 that acquires actual running data that is data related to states inside and outside of a vehicle in running on a road; a test apparatus 3 each of which performs a drive test or an operation test of a vehicle or a part of the vehicle in accordance with a set test condition; and a test management apparatus 4 that reproduces a part or all of the running states indicated by the actual running data in the test apparatus 3. Further, the test management apparatus 4 receives test result data that is data indicating a test result by the test apparatus 3, and comparably outputs the test result data and the actual running data.

Description

technical field [0001] The present invention relates to a vehicle test system and the like for testing a vehicle such as an automobile or a part of the vehicle. Background technique [0002] In the past, in order to develop vehicles and solve problems of vehicles, various test devices such as chassis dynamometers for testing the entire vehicle and transmitter dynamometers for testing the engine unit as a part of the vehicle have been used. [0003] In such a test device, by setting predetermined test conditions, it is possible to generate a simulated or imaginary load and environment, which is considered to be generated by actual driving, and to act on each part of the vehicle. [0004] For example, the load and environment can also be obtained by actually driving a car on the road. In Patent Document 1, a chassis dynamometer is set in a chassis dynamometer in which a test condition such that a load equivalent to the measured gradient is applied to the vehicle is preliminar...
