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 exhaust gas test apparatus for a vehicle comprising:

a processor connected to a display and configured to

sequentially acquire actual running data of the vehicle, via sensors, under execution of a running exhaust gas test on a road by a driver,

sequentially produce tendency data indicating a tendency as to whether or not the running exhaust gas test is valid, based on the actual running data during the running exhaust gas test,

comparably output the tendency data and a predetermined condition for validating the running exhaust gas test on the display, and

sequentially update contents of the display during the running exhaust gas test to indicate state of progress towards meeting requirements for the running exhaust gas test to be valid.

2. The on-road running exhaust gas test apparatus according to claim 1, wherein in the case where a running mode of the running exhaust gas test is defined by one or more predetermined running mode definition parameters and the running mode satisfies the predetermined condition, the running exhaust gas test is determined to be valid, and wherein the processor is further configured to sequentially obtain values of the one or more running mode definition parameters based on the actual running data and to sequentially output the values of the parameters as the tendency data.

3. The on-road running exhaust gas test apparatus according to claim 2, wherein a speed distribution in a test travel is used as the running mode definition parameters.

4. The on-road running exhaust gas test 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 on-road running exhaust gas test 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 exhaust gas test apparatus for a vehicle, having a program recorded therein for allowing a processor of the on-road running exhaust gas test apparatus to exhibit functions of:

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

a tendency data output part for

sequentially producing tendency data indicating a tendency as to whether or not the running exhaust gas test is valid, based on the actual running data during the running exhaust gas test,

comparably outputting the tendency data and a predetermined condition for validating the running exhaust gas test on a display, and

sequentially updating contents of the display during the running exhaust gas test to indicate state of progress towards meeting requirements for the running exhaust gas test to be valid.
