■WLTP(Worldwide harmonized Light vehicles Test Procedure)
Until now, fuel efficiency measurement methods differed in each country, such as JC08 in Japan and NEDC in Europe, but WLTP is the common measurement method worldwide.
WLTC is the driving cycle specified by WLTP.
＜Class＞
The driving cycle changes depending on the class divided by the vehicle's maximum speed and PMR (ratio of rated output to empty vehicle weight).
＜Test vehicle weight＞
The test vehicle weight is defined as follows.
＜Driving cycle＞
The driving cycles are different for Class 1, Class 2, and Class 3, and the following is the driving mode for Class 3b. The driving cycles are Low, Medium, High, and Extra High.
＜Driving cycle data＞
The csv files of time series data for each mode are below. The data is originally in 1 second increments, but for detailed simulations we have also included data in 0.1 second increments (I just linearly interpolated the 1 second data).
＜Application contents＞
Application details for fuel efficiency or electrical energy consumption vary depending on the engine, hybrid, or electric vehicle. It differs depending on the country, and in Japan, the fuel efficiency of an engine is ○○ km/L (converted from CO2 emissions g/km), but for electric vehicle it is △△Wh/km.
Plug-in hybrids apply for a cycle in which the vehicle runs only on the battery (CD cycle) and a mode in which it runs using both the battery and the engine (CS cycle).
