Perhaps you should try some spelling variations:
"vehicle-based real-time pi measured system" » "vehicle-based real-time pi measure system", "vehicle-based real-time pi measures system", "vehicle-based real-time pi unmeasured system", "vehicle-based real-time via measured system", "vehicle-based real-time a 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 _ measure system", "vehicle-based real-time _ measures system", "vehicle-based real-time _ unmeasured system"

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

• 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 _ measured system\"))*".
• Removing quotes may allow a broader search: (( vehicle-based real-time pi measured system ) OR ( vehicle-based real-time _ measured system ))*.
