Patent number: 11912262Abstract: A vehicle includes an air-conditioning (AC) compressor, an engine, a belt-integrated starter generator (BISG), and a controller. The controller, responsive to detecting a first AC compressor engagement condition, compares a first AC torque demand that is required to engage the AC compressor with an available torque from the BISG. The controller further, responsive to the available torque being insufficient to engage the AC compressor, engages the AC compressor using the available torque from the BISG and an engine torque from the engine to compensate a torque shortfall between the AC torque demand and the available torque by retarding spark timing and increasing air intake.Type: GrantFiled: November 20, 2020Date of Patent: February 27, 2024Assignee: Ford Global Technologies, LLCInventors: Tom Leroy, Nicholas Dashwood Crisp, Athul Raj, Grant Cooper

Patent number: 10243494Abstract: Method and systems are provided for adjusting an engine torque in response to changes in a desired engine torque. In one example, a method may comprise responsive to increasing desired engine torques, monotonically decreasing an alternator torque to a first level from a second level when not injecting fuel to engine cylinders, and stepping up the alternator torque from the first level to the second level while initiating engine combustion, and then monotonically decreasing the alternator torque from the second level to the first level in response to the alternator torque reaching the first level. In this way, a method may comprise adjusting a load exerted on an engine by an alternator mechanically coupled to said engine during both cylinder combustion, and during non-fueling conditions.Type: GrantFiled: February 12, 2018Date of Patent: March 26, 2019Assignee: Ford Global Technologies, LLCInventors: Tobias John Pallett, Christopher John Teslak, Yanan Zhao, Nicholas Dashwood Crisp, Rajit Johri, Jeffrey Allen Doering

Patent number: 10174839Abstract: A method for reducing the fuel used by an engine of a motor vehicle. The method limits the speed at which the engine can rotate when a predefined engine upper speed limit NECOUL for the particular gear in which the motor vehicle is currently operating has been reached or limiting the road speed of the motor vehicle when a predefined vehicle road speed has been reached. The use of engine or road speed limiting combined with the alerting of the driver via an indicator that an upshift is desired to improve fuel economy encourages the driver to execute an upshift.Type: GrantFiled: February 17, 2016Date of Patent: January 8, 2019Assignee: Ford Global Technologies, LLCInventors: Anthemios Philemon Petridis, Nicholas Dashwood Crisp
