Abstract

A vehicle test system according to the present invention intends to comprehensively manage and operate multiple types of test apparatuses to smoothly perform vehicle development, problem correction, and the like. For this purpose, the vehicle test system includes an actual running data acquisition apparatus that acquires actual running data that is data related to states inside and outside of a vehicle in running on a road; multiple types of test apparatuses each of which performs a drive test or an operation test of a vehicle or a part of the vehicle in accordance with set test conditions; and a test condition data generation apparatus that from the actual running data, generates test condition data indicating test conditions necessary to reproduce a part or all of the running states indicated by the actual running data in a test apparatus specified from among the multiple types of test apparatuses.

First claim

What is claimed is:

1. A vehicle test system comprising:
an actual running data acquisition apparatus that acquires actual running data related to states inside and outside of a vehicle running on a road;
multiple types of test apparatuses each of which includes a dynamometer, and performs a drive test or an operation test of a vehicle or a part of the vehicle in accordance with a test condition; and
a test condition data generation apparatus adapted to generate, from the actual running data, test condition data indicating the test condition for reproducing a part or all of running states indicated by the actual running data, and performs a drive test or an operation test of a vehicle or a part of the vehicle in accordance with a set test condition, wherein
the test condition data generation apparatus comprises a simulation preference order setting part adapted to specify actual running data content to be preferentially simulated among contents of actual running data,
a test apparatus specifying part adapted to specify one or more of the dynamometers by receiving input, and
a test condition data generation part adapted to generate the test condition data from the actual running data content specified in the simulation preference order setting part, and to transmit the test condition data to one or more of the dynamometers specified in the test apparatus specifying part.

2. The vehicle test system according to claim 1 , wherein
the actual running data acquisition apparatus transmits the actual running data to the test condition data generation apparatus in real time, and
the test condition data generation apparatus is configured to transmit the test condition data to the multiple types of test apparatuses specified by the test apparatus specifying part.

3. A test condition data generation apparatus configured to receive data from an actual running data acquisition apparatus that acquires actual running data related to running states inside and outside of a vehicle running on a road,
the test condition data generation apparatus generating, from the actual running data, test condition data indicating a test condition for reproducing a part or all of the running states indicated by the actual running data in a test apparatus specified from among multiple types of test apparatuses each of which comprises a dynamometer, and performs a drive test or an operation test of a vehicle or a part of the vehicle in accordance with the test condition, wherein
the test condition data generation apparatus comprises a simulation preference order setting part adapted to specify actual running data content to be preferentially simulated among contents of actual running data,
a test apparatus specifying part adapted to specify one or more of the dynamometers by receiving input, and
a test condition data generation part adapted to generate the test condition data from the actual running data content specified in the simulation preference order setting part, and to transmit the test condition data to one or more of the dynamometers specified in the test apparatus specifying part.

4. A vehicle test method comprising:
acquiring actual running data related to states inside and outside of a vehicle running on a road, wherein the actual running data includes dependent contents that are dependent on each other;
generating on a basis of the actual running data, test condition data indicating a test condition for reproducing a part or all of running states indicated by the actual running data in a test apparatus specified from among multiple types of test apparatuses each of which comprises a dynamometer, and performs a drive test or an operation test of a vehicle or a part of the vehicle in accordance with the test condition;
specifying one or more of the dynamometers by receiving input;
specifying actual running data content to be preferentially simulated among contents of actual running data;
generating the test condition data from the actual running data content specified; and
transmitting the test condition data to one or more of the specified dynamometers.
