Abstract(E)This paper proposes a slip detection method for inverters of a BEV (Battery Electric Vehicle), which drives a vehicle by one traction motor with a differential gear and driveshafts. It is observed that the sign (positive/negative) of motor rotation jerk differs when tire slip happens. Based on this phenomenon, the proposed slip detection method determines the start of tire slip when motor rotation jerk of a while after oscillation occurs is positive values dominantly. According to vehicle dynamics simulation, it is verified that the method can detect slip start after actual slip occurs earlier than the former slip detection method.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
