Abstract: An exhaust gas analysis system is adapted to include an exhaust gas circulation line through which exhaust gas flows, an exhaust gas collection line adapted to collect the exhaust gas from the exhaust gas circulation line and introduce the collected exhaust gas into an exhaust gas analysis device, a continuous analysis line adapted to, separately from the diluted exhaust gas collection line, collect the exhaust gas from the exhaust gas circulation line for continuous analysis, a continuous analyzer provided in the continuous analysis line, and an information processing unit adapted to, on the basis of an analysis result by the continuous analyzer at the time of the collection into the exhaust gas analysis device, determine whether a measurement result of the exhaust gas introduced into the exhaust gas analysis device falls within a preset range, or determine a measurement range used to measure the exhaust gas introduced into the exhaust gas analysis device.

Abstract: A driving mode display device of this invention makes it possible to more smoothly and efficiently conduct a vehicle exhaust gas measurement test using a chassis dynamometer and also makes it possible to further improve the security. The driving mode display device comprises an operational state display part that displays an operational state of equipment that is necessary for an exhaust gas measurement test to a test driver and an input receive part that receives an input that is for the test driver to control an operation of the equipment.

Abstract: A vehicle driving mode display device judges whether or not a following first condition or a following second condition is satisfied in a case that a vehicle is driven within a tolerance range, and if satisfied, issues a warning. The first condition is a case in which a difference between a standard speed indicated by the running speed pattern and the vehicle speed is gradually widened as time elapses. The second condition is a case in which the vehicle speed exceeds the tolerance range within a predetermined allowable time period when an acceleration at the moment is presumed to be kept.
