Abstract
The first report showed the correlation between the meteorological environment and the temperature environment inside the exposed vehicle in Okinawa, and proposed a method for estimating the temperature inside the vehicle from the meteorological data by using the relation Ci in the invehicle environment specific heat. In this second report, meteorological data from arbitrary areas other than Okinawa were used to increase the versatility of the method for estimating the temperature inside the exposed vehicle. The enhanced in-vehicle environmental specific heat Ci was determined to be unique to the vehicle and not to change depending on the area. The Ci value calculated from a short-term exposure test can be expanded to the in-vehicle temperature history of a one-year exposure test that is not actually performed. In addition, the yearly in-vehicle temperature history can be estimated from the yearly weather data in any area of the world without actually performing an exposure test in that area. By estimating the in-vehicle temperature history from the meteorological data of various areas around the world, the base in-vehicle temperature history can be obtained for selecting the accelerated deterioration test conditions.
