Patent number: 11118952Abstract: In some examples, a system includes an airflow sensor disposed at least partially within an air intake system for an engine. The airflow sensor may be configured to measure a flow rate of air flowing past the airflow sensor in the air intake system, and includes a sensor element and a heater associated with the sensor element. A heater control circuit may control the heater to control a temperature of the sensor element. Further, a processor may be configured by executable instructions to cause the heater control circuit to, in a first operation mode, maintain the sensor element at a higher temperature range, and, in a second operation mode, maintain the sensor element at a lower temperature range that is above an ambient temperature and that is lower than the higher temperature range.Type: GrantFiled: July 23, 2019Date of Patent: September 14, 2021Assignee: HITACHI ASTEMO AMERICAS, INC.Inventors: Frank Warren Hunt, Anthony P. Boone, Prashanth Avireddi, Nicholas Ryan Dal Pra, Zachariah Rabatah

Patent number: 10781775Abstract: In some examples, a mass airflow sensor apparatus includes a housing having a tubular bore for passage of air, with an airflow sensor disposed at least partially within the tubular bore. The airflow sensor may be configured to measure a flow rate of air flowing past the airflow sensor. A focus component may be disposed upstream of the mass airflow sensor, the focus component including a cylindrical tubular focus member suspended within the bore. Further, a nozzle may be disposed upstream of the focus component. The nozzle may include a conical inner surface angled toward a center of the bore. In addition, a grid component may be disposed upstream of the focus component. The grid component may include a mesh grid including a plurality of openings for smoothing a flow of air flowing toward the airflow sensor.Type: GrantFiled: January 31, 2018Date of Patent: September 22, 2020Assignee: HITACHI AUTOMOTIVE SYSTEMS AMERICAS, INC.Inventors: Prashanth Avireddi, Anthony Boone, Frank Hunt, Naoki Oka, Zachariah Rabatah

Patent number: 10480604Abstract: A shock absorber having an outer tube, an inner tube disposed coaxially in the outer tube and a piston reciprocally mounted in the inner tube. The interior of the inner tubes forms a working chamber for hydraulic oil while an annular replenishment chamber is formed between the inner and outer tubes. An improved base plate and base cage assembly facilitates fluid flow from the replenishment chamber to the working chamber during an extension cycle of the shock absorber.Type: GrantFiled: July 27, 2015Date of Patent: November 19, 2019Assignee: Hitachi Automotive Systems Americas, Inc.Inventors: Michael Romano, Jahan Assadi, Prashanth Avireddi, Nikhil Seera

Patent number: 10443595Abstract: A fuel pump having a housing defining a pump chamber and an inlet and outlet fluidly connected to the pump chamber. A one way check valve is disposed fluidly in series between the pump chamber and the outlet and is oriented to allow fluid flow from the pump chamber and to the outlet when the check valve is open. A venturi tube is fluidly connected in series between the pump chamber and the outlet which effectively dampens noise pulsations. An inlet valve to the pump chamber has an anchor attached to a valve member and the stationary core. A conical surface on the core abuts against a complementary conical surface on the anchor when the valve is either in its fully open or fully closed position.Type: GrantFiled: April 20, 2015Date of Patent: October 15, 2019Assignee: Hitachi, Ltd.Inventors: Prashanth Avireddi, Nikhil Seera, Akira Inoue

Patent number: 10259468Abstract: The driver's driving behavior will be recorded and a signature will be created either on vehicle or on a cloud data center. The driver signature can be accessed using secure authentication by any vehicle he will be driving. The data collection is a continuous process monitoring driving behavior of the driver. The guidelines from OEM are used to compare driver signature with ideal driving characteristics. Changes are pushed to the vehicle controller to modify controls of individual automotive components to adjust the efficiency of vehicle and improve the ride comfort for the driver. The changes to be made can be decided on a remote cloud system or on the vehicle.Type: GrantFiled: June 15, 2017Date of Patent: April 16, 2019Assignee: HITACHI, LTD.Inventors: Prashanth Avireddi, Heming Chen

Patent number: 10094349Abstract: A fluid valve assembly having a housing with a valve seat which forms a fluid port. A valve is movable along an axis relative to the port between an open and a closed position. This valve includes a protrusion complementary in shape to, but slightly smaller than, the port. The protrusion is at least partially positioned in the port when the valve is in its closed position at which time a clearance space between the port and the protrusion is sufficiently small to prevent fluid flow through the port. A main spring disposed between the housing and the valve resiliently urges the valve towards its closed position. A second spring is also operatively positioned between the valve and the housing which urges the valve away from the valve seat towards its open position and prevents contact between the valve and the valve seat.Type: GrantFiled: May 8, 2014Date of Patent: October 9, 2018Assignee: Hitachi, Ltd.Inventor: Prashanth Avireddi

Publication number: 20170051715Abstract: A fuel rail for a direct injection engine. The fuel rail includes an elongated tubular housing which defines an elongated main chamber. An elongated tube is disposed in the main chamber of the housing and defines an inlet chamber inside of the tube and an annular outlet chamber between the housing and the tube. The tube has a fuel inlet open to its inlet chamber and adapted for connection with a fuel pump. At least two orifices are formed through the tube which fluidly connects the inlet chamber with the outlet chamber. The orifices are positioned and sized to minimize fuel pressure gradients in the fuel rail caused by fuel injection by the fuel injectors.Type: ApplicationFiled: August 19, 2015Publication date: February 23, 2017Inventors: Donald J. McCune, Prashanth Avireddi
