The oxygen partial pressure for internal combustion engines is a major factor that affects engine performance. At high altitudes, engine performance is degraded because the reduction of oxygen partial pressure makes less air flow into the combustion chamber. This is a general characteristic of high-altitude driving conditions. The ambient pressure is a required input for engine management system(EMS). Functions such as fuel injection, exhaust gas recirculation (EGR) and canister purge need to know the ambient pressure to perform the necessary control functions. For the purpose, some of local testing at the real high altitude inevitably has to perform to obtain reliable EMS calibration data, although it requires much time and cost. Instead of the local testing, special facility (chassis dynamometer as Super Wind Tunnel) which can control the ambient pressure may be used but, there is a limit to simulate all possible actual road driving conditions. Therefore, the present research was designed for a vehicle simulator which can reproduce vehicle driving conditions by altitude at a sea level or available altitudes in Korea, to enable the optimization of engine control parameters. This design was examined as an effective countermeasure enough to obtain minimum EMS calibration data required at each altitude, save local testing cost and shorten vehicle development lead time.
