Publication number: 20220412755Abstract: 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.Type: ApplicationFiled: September 2, 2022Publication date: December 29, 2022Inventors: Bryan John Nagy, Michael Voznessensky, Brent Goldman, Robert Michael S Dean, Jian Wen, Yanbo Zhao

Patent number: 11480171Abstract: The present invention provides a vertical, axial flow oil pump (10). The oil pump includes: a casing (11), the casing having a cylindrical shape as a whole and being able to rotate around its own central axis (O); a suction port (12), located at a lower end of the casing in an axial direction, and configured to suck oil into the oil pump; a discharge port (13), located at an upper end of the casing in the axial direction, and configured to discharge the oil from the oil pump to outside; and an impeller (14), provided in and formed integrally with the casing. The impeller rotates together with the casing when the casing rotates, so that the oil is flowed from the suction port to the discharge port. The present invention also provides a scroll compressor having the oil pump.Type: GrantFiled: December 28, 2020Date of Patent: October 25, 2022Assignee: Danfoss (Tianjin) Ltd.Inventors: Liqian Ren, Jian Jin, Jing Zhao, Yanbo Zhao

Publication number: 20210115913Abstract: A flow regulating valve and a compressor with the flow regulating valve are disclosed. The flow regulating valve includes: a valve seat in which a passage is formed to allow fluid to enter; a guide member protruded outwards from the valve seat; a piston which is disposed on the outside of the valve seat, forms a fluid inlet with the valve seat, and is capable of being reciprocated along the guide member; and a biasing member biasing the piston in a direction away from the valve seat. A force exerted by the incoming fluid on the piston is opposite in direction to a biasing force exerted by the biasing member on the piston. The piston is able to be moved to different positions under the action of different forces to form fluid inlets of different widths with the valve seat, thereby controlling the mass flow rate of the incoming fluid (especially liquid).Type: ApplicationFiled: October 1, 2020Publication date: April 22, 2021Inventors: Lixin Han, Xiaodong Wang, Kun Qian, Haiyun Ma, Wenhu Yao, Yanbo Zhao, Kang Zheng
