Patent number: 11053872Abstract: Methods and systems are provided for coordinating operation of a high pressure EGR control loop with a boost pressure control loop. In one example, following a tip-in, turbine vane position may be adjusted as a function of a maximum permissible exhaust pressure upstream of a turbocharger turbine. The maximum permissible exhaust pressure may be determined as a function of a HP EGR valve position at the time of the tip-in.Type: GrantFiled: April 9, 2020Date of Patent: July 6, 2021Assignee: Ford Global Technologies, LLCInventors: Jon Dixon, Ian Halleron, Andres Arevalo

Patent number: 10247115Abstract: A system and method for increasing engine heating rate to facilitate early introduction of exhaust gas recirculation after a cold start include operating an electric machine connect to the engine to apply a load to the engine. The electric machine may be operated as a generator to produce an increased engine torque demand and increase the rate of engine heating until an engine temperature and an exhaust temperature exceed corresponding thresholds. Operation of the electric machine as a generator may be stopped in response to a battery state of charge exceeding a threshold, or engine load exceeding a threshold.Type: GrantFiled: August 10, 2016Date of Patent: April 2, 2019Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Paspuleti Ashish Kumar Naidu, Ian Halleron, Peter George Brittle, James Wright

Patent number: 10072625Abstract: A vehicle start-stop system includes an engine and a controller. The controller is programmed to operate the system in a first mode when a first input is selected, and in a second mode when a second input is selected. The controller is further programmed to inhibit engine stop in response to being in the first mode and an evaporator temperature having a first value, and stop the engine in response to being in the second mode and the evaporator temperature having the first value.Type: GrantFiled: May 30, 2017Date of Patent: September 11, 2018Assignee: Ford Global Technologies, LLCInventors: David Hesketh, Themi Philemon Petridis, Ian Halleron, Christopher Edward Pedlar

Patent number: 9878713Abstract: A method and apparatus for controlling the operation of an engine of a motor vehicle is disclosed in which the engine is restarted while the vehicle is in motion by bump starting it if the speed of the vehicle falls within predetermined speed limits but is otherwise restarted using a starter motor. The number of starts for which the starter motor is used is thereby reduced advantageously reducing wear of the starter motor and increasing the life and/or reducing the duty cycle of the battery or source of power used for the starter motor.Type: GrantFiled: March 22, 2012Date of Patent: January 30, 2018Assignee: Ford Global Technologies, LLCInventors: Themi Philemon Petridis, Peter George Brittle, Ian Halleron
