Abstract

In order to efficiently and reliably perform a valid field test, there are provided: a running data acquisition part for sequentially acquiring actual running data of a vehicle under execution of a running test on a road by a driver; and a tendency data output part for sequentially producing and outputting tendency data indicating a tendency as to whether or not the running test is valid, based on the actual running data during the running test.

Claims

1. An on-road running test apparatus for a vehicle comprising:

a running data acquisition part for sequentially acquiring actual running data of the vehicle under execution of a running test on a road by a driver; and

a tendency data output part for sequentially producing and outputting tendency data indicating a tendency as to whether or not the running test is valid, based on the actual running data during the running test.

2. The on-road running test apparatus according to claim 1, wherein, in the case where a running mode of the running test is defined by one or more predetermined running mode definition parameters and the running mode satisfies a predetermined condition, the running test is determined to be valid, and

wherein the tendency data output part sequentially obtains values of the one or more running mode definition parameters based on the actual running data and sequentially outputs the values of the parameters as the tendency data.

3. The vehicle drive system testing apparatus according to claim 2, wherein a speed distribution in a test travel is used as the running mode definition parameters.

4. The vehicle drive system testing apparatus according to claim 2, wherein a two-dimensional amount of a rotational speed of an engine and an engine torque is used as the running mode definition parameters.

5. The vehicle drive system testing apparatus according to claim 2, wherein a two-dimensional amount of an amount of CO2 emission and a vehicle speed is used as the running mode definition parameters.

6. A recording medium mounted on an on-road running test apparatus for a vehicle, having a program recorded therein for allowing the on-road running test apparatus to exhibit functions of:

a running data acquisition part for sequentially acquiring actual running data of the vehicle under execution of a running test on a road by a driver; and

a tendency data output part for sequentially producing and outputting tendency data indicating a tendency as to whether or not the running test is valid, based on the actual running data during the running test.
