Patent number: 11060464Abstract: Systems and methods for operating an internal combustion engine are described. In one example, an engine's position is adjusted during engine stopping so that the engine may be less likely to stop at a crankshaft angle where rotating a fuel pump may increase engine cranking torque due to work performed by the fuel pump.Type: GrantFiled: February 8, 2019Date of Patent: July 13, 2021Assignee: Ford Global Technologies, LLCInventors: M. Scott Christensen, Michael Bastanipour, David Hancock, Alexander O'connor Gibson

Patent number: 10968838Abstract: An engine speed control device performing: a first PID gain calculation step of calculating a target engine speed to thereby calculate a first PID gain based on an engine speed deviation between the target engine speed and an engine speed; a target rack position calculation step of correcting the first PID gain based on a cooling water temperature to thereby calculate a target rack position of a fuel injection pump; a second PID gain calculation step of calculating a second PID gain based on a rack position deviation between the target rack position and a rack position; and a rack control signal producing step of correcting the second PID gain based on a lubricating oil temperature to thereby produce a rack control signal. The engine speed control device thus controls an engine speed by controlling the rack position based on the rack control signal.Type: GrantFiled: March 26, 2018Date of Patent: April 6, 2021Assignee: YANMAR POWER TECHNOLOGY CO., LTD.Inventors: Ryosuke Shimomura, Ryota Iwano, Tomoaki Morita

Patent number: 10933876Abstract: A host vehicle includes a combustion engine configured to provide a propulsion torque to satisfy a propulsion demand. The vehicle also includes at least one sensor configured to detect a position of a reference vehicle. A vehicle controller is programmed to determine a path between a current host vehicle location and an upcoming intersection. The controller is also programmed to forecast a path clearance time at which the host vehicle is able to traverse the intersection in response to sensor data indicating the reference vehicle moving within the path ahead of the host vehicle. The controller is further programmed to deactivate the engine prior to a host vehicle stop based on the path clearance time being greater than a time threshold.Type: GrantFiled: January 14, 2019Date of Patent: March 2, 2021Assignee: GM Global Technology Operations LLCInventors: Mohammad Naserian, Allan K. Lewis

Patent number: 10920731Abstract: A method for controlling a vehicle includes: receiving a detection signal to perform an idle stop and go (ISG) function; and controlling the vehicle to enter into an ISG state where a fuel supply to an engine is cut off and the engine stops when the vehicle decelerates or stops in response to the detection signal. The detection signal includes a fuel cut off signal that is in on state when the vehicle decelerates and in off state at a reference revolution per minute (RPM) of the engine, a gear engagement signal, and a brake pedal signal indicating whether the brake pedal of the vehicle is operated. A controller of the vehicle generates an ISG entry signal based on the fuel cut off signal, the gear engagement signal, and the brake pedal signal to enter the vehicle into the ISG state.Type: GrantFiled: June 19, 2018Date of Patent: February 16, 2021Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Jung Hwan Bang, Young Ho Jung, Tae Suk Lee

Patent number: 10906537Abstract: A method of determining a risk situation of a collision of an autonomous vehicle is provided. The method includes recognizing a preceding vehicle and measuring a variable factor including a distance or a relative speed between a traveling vehicle and the preceding vehicle. Whether a collision is capable of being avoided by turning or braking is determined based on the variable factor.Type: GrantFiled: November 14, 2018Date of Patent: February 2, 2021Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Kyun Sang Park, Sang Hyup Lee, Joung Hee Lee

Patent number: 10832870Abstract: Devices and methods are disclosed for reducing vibration and noise from capacitor devices. The device includes a circuit board, and first and second capacitor structures. The second capacitor structure has substantially the same properties as the first and is coupled to the opposite face of a supporting structure substantially opposite of the first capacitor structure. The first and second capacitor structures can receive substantially the same excitation signals, can be electrically connected in parallel or in series. The first and second capacitor structures can be discrete capacitors, capacitor layers, stacks or arrays of multiple capacitor devices, or other capacitor structures. Stacks of multiple capacitor devices can be arranged symmetrically about the supporting structure. Arrays of multiple capacitor devices can be arranged with offsetting capacitors on the opposite face of the supporting structure substantially opposite one another.Type: GrantFiled: November 13, 2017Date of Patent: November 10, 2020Assignee: ALLISON TRANSMISSION, INC.Inventors: Steven D. Slagle, James D. Shaw, George C. Mimms, Kyle E. Erickson

Patent number: 10773720Abstract: Systems and methods for implementing a start-stop feature on a vehicle powered at least in party by an internal combustion engine are described. The method includes receiving, at an electronic control unit (“ECU”) of the vehicle, an indication that the vehicle is in line at a drive-thru. The method further includes determining, by the ECU, a number of start-stop events anticipated during the drive-thru. The method includes determining, by the ECU, an approximate stop time for each of the number of start-stop events. The method further includes determining, by the ECU, that a battery of the vehicle has enough remaining charge to power a plurality of vehicle components during implementation of the start-stop feature. The method includes implementing, by the ECU, the start-stop feature in which the internal combustion engine is turned off for at least a portion of the time when the vehicle is stopped.Type: GrantFiled: September 21, 2018Date of Patent: September 15, 2020Assignee: Cummins, Inc.Inventors: Martin T.

Patent number: 10768075Abstract: A system and method for determining a frequency response of a power steering system is disclosed including a steering assist motor configured to generate an assist torque about an axis of a steering shaft when activated. The method includes monitoring, by a controller, a torque transducer that measures a steering output torque of the steering shaft experienced during a first frequency sweep and a second frequency sweep. The method also includes determining, by the controller, a transfer function based on the steering output torque monitored during the first frequency sweep and the second frequency sweep, where the transfer function indicates the response by the power steering system.Type: GrantFiled: June 14, 2018Date of Patent: September 8, 2020Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Bo Yu, Ian Y.
