Perhaps you should try some spelling variations:
"vehicle-based real-time pi measured system" » "vehicle-based real-time pi measures system", "vehicle-based real-time pi unmeasured system", "vehicle-based real-time pi measures systems", "vehicle-based real-time via measured system", "vehicle-based real-time a measured system", "vehicle-based real-time 4 measured system", "vehicle-based real-time pvi measured system", "vehicle-based real-time i measured system", "vehicle-based real-time ii measured system", "vehicle-based real-time pid measured system", "vehicle-based real-time pie measured system", "vehicle-based real-time p measured system"
"vehicle-based real-time _ measured system" » "vehicle-based real-time _ measures system", "vehicle-based real-time _ unmeasured system", "vehicle-based real-time _ measures systems"
"vehicle-based real-time pi measure system" » "vehicle-based real-time pi measuring system", "vehicle-based real-time pi pressure system", "vehicle-based real-time pi closure system", "vehicle-based real-time pvi measure system", "vehicle-based real-time i measure system", "vehicle-based real-time ii measure system", "vehicle-based real-time pid measure system", "vehicle-based real-time pie measure system", "vehicle-based real-time p measure system"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("vehicle-based real-time pi measured system") OR ("vehicle-based real-time pi measure system"))) OR ("vehicle-based real-time _ measured system")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"vehicle-based real-time pi measured system\") OR (\"vehicle-based real-time pi measure system\"))) or (\"vehicle-based real-time _ measured system\"))".
• Removing quotes may allow a broader search: (((( vehicle-based real-time pi measured system ) OR ( vehicle-based real-time pi measure system ))) or ( vehicle-based real-time _ measured system )).
• Adding a wildcard symbol may retrieve word variants: (((("vehicle-based real-time pi measured system") OR ("vehicle-based real-time pi measure system"))) or ("vehicle-based real-time _ measured system"))*.
