Abstract(E)	Afault detection mechanism using the tire rotational dynamics is proposed to detect the motor bearing fault for the electric vehicle with four direct-driven wheel motors. If partial fault is detected, fault hiding is implemented by adding feedforward compensation of the estimated bearing damping torque to the wheel motor torque distributed by the control allocation. If complete fault is detected, control allocation is reconfigured to use the other faulty free wheels for torque distribution. Simulation results show that the proposed method can achieve active fault tolerant control while maintaining the performance of electronic stability control for the test maneuvers.

About search

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.
