Title:
ROAD RUNNING TEST APPARATUS, ROAD RUNNING TEST METHOD, AND PROGRAM FOR ROAD RUNNING TEST APPARATUS
Document Type and Number:
Japanese Patent JP2020046175
Kind Code:
A
Abstract:
To provide a road running test apparatus capable of evaluating in real time whether a predetermined running mode is realized at the time of a road running test by using an alternative index having a smaller calculation load than in the past.SOLUTION: The road running test apparatus includes: an exhaust gas analyzer 3 mounted on a vehicle V, for analyzing components of exhaust gas emitted from the vehicle V traveling on a road; a traveling data acquisition unit 51 for acquiring at least a vehicle speed or an acceleration from the vehicle V traveling on the road; an acceleration number of times calculation unit 52 for calculating an acceleration number of times during traveling on the road of the vehicle from the vehicle speed or acceleration acquired by the traveling data acquisition unit; a reference acceleration number of times storage unit 53 for storing a reference acceleration number of times when traveling in a predetermined traveling mode on a chassis dynamo; and a comparison data outputting comparison output unit 54 for outputting the reference acceleration number of times and the acceleration number of times during road running calculated by the acceleration number of times calculation unit in a comparable manner.SELECTED DRAWING: Figure 1
