Patent number: 9718454Abstract: Apparatuses, methods and systems for hybrid powertrain control are disclosed. Certain example embodiments control an internal combustion engine and a motor/generator of a hybrid electric powertrain. Example controls may determine a total output demanded of a powertrain based at least in part upon an operator input, a battery output target based upon a battery state of charge and independent of the operator input, and an engine output target based upon the total output demanded and the battery output target. Such example controls may further determine a constrained engine output target, a modified battery output target based upon the total output demanded and the constrained engine output target, and a constrained battery output target based upon the modified battery output target and a battery constraint. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and figures.Type: GrantFiled: November 21, 2013Date of Patent: August 1, 2017Assignee: Cummins Inc.Inventors: Martin T.

Patent number: 7234552Abstract: A method for heating a battery in a hybrid electric vehicle. The hybrid electric vehicle has an engine, a battery, a motor generator powered by the engine or the battery, and a control module. The method includes the steps of determining a battery temperature and determining whether a tip-in event, a tip-out event, or a terminal voltage event has occurred. The polarity of the battery is reversed if the battery temperature is below a predetermined value and if a tip-in event, a tip-out event, or a terminal voltage event has occurred.Type: GrantFiled: September 19, 2003Date of Patent: June 26, 2007Assignee: Ford Global Technologies, LLCInventors: Mukunda V.

Patent number: 7117964Abstract: A control system for a hybrid powertrain for a hybrid electric vehicle with an internal combustion engine and an electric drive system including an electric motor, a battery and a generator. The control system includes a system controller that monitors actual battery power in a closed-loop fashion and detects an error between actual battery power and a request for battery power. The engine power is corrected so that the battery is used at its intended level, thereby avoiding unnecessary charging and discharging.Type: GrantFiled: September 22, 2003Date of Patent: October 10, 2006Assignee: Ford Global Technologies, LLCInventors: Ming Lang Kuang, Fazal U.

Patent number: 6553287Abstract: The invention is a controller for a hybrid electric vehicle (HEV) to meet driver expectation when forward wide open throttle (WOT) acceleration is requested while optimizing the total powertrain system efficiency and performance, especially when the engine is not even running. The controller can consider accelerator position, PRNDL position, and vehicle speed and start the engine if an estimated sum torque of a traction motor and generator motor is less than the calculated sum torque output of the traction motor and the engine at any given speed. Other control variables can include battery condition such as operating capacity, temperature, and state of charge. A constant can be added to allow a prestart of the engine to assure it is available when needed to maintain vehicle WOT acceleration requests.Type: GrantFiled: October 19, 2001Date of Patent: April 22, 2003Assignee: Ford Global Technologies, Inc.Inventors: Joseph Gerald Supina, Ming Lang Kuang, Vincent Freyermuth
