US Patent:

20130173666, Jul 4, 2013

Filed:

Dec 29, 2011

Appl. No.:

13/340335

Inventors:

Yan Qi - Fremont CA, US
Yu Xu - Burlingame CA, US
Olli Pekka Kostamaa - Santa Monica CA, US
Jian Wen - Irvine CA, US

International Classification:

G06F 17/30

US Classification:

707798, 707E17011, 707E1701

Abstract:

Techniques for data assignment from an external distributed file system (DFS) to a database management system (DBMS) are provided. Data blocks from the DFS are represented as first nodes and access module processors of the DBMS are represented as second nodes. A graph is produced with the first and second nodes. Assignments are made for the first nodes to the second nodes based on evaluation of the graph to integrate the DFS with the DBMS.

G05D 1/02
B60W 60/00
G08G 1/0968

Abstract:

Various examples are directed to systems and methods for controlling an autonomous vehicle. For example, a navigator system at an autonomous vehicle may generate a plurality of local routes beginning at a vehicle location and extending to a plurality of local route end points. The navigator system may access general route cost data, the general route cost data describing general route costs from the plurality of local route end points to a trip end point. The navigator system may select the first local route of the plurality of routes based at least in part on the general route cost data. A vehicle autonomy system at the autonomous vehicle may begin to control the autonomous vehicle along the first local route.
