Patent number: 9695760Abstract: A method/system for maintaining the energy efficiency history of predicted route segments in a database, providing adaptive feedback to hybrid vehicle controls, and displaying the energy efficiency history to the driver. As the vehicle travels on a route, the system stores energy efficiency information for route segments. The system may include sensors, a memory, and a processor to learn energy efficiency information based on how fuel and battery power are used over a route segment and/or route. The method/system may utilize energy efficiency information to adjust a start/stop engine threshold of a hybrid vehicle. When the processor predicts that the vehicle will travels on the predicted route segment again, the vehicle may optimize powertrain parameters such as the start/stop engine threshold during traveling on the predicted route segment and/or before reaching the predicted route segment.Type: GrantFiled: March 31, 2014Date of Patent: July 4, 2017Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Mohammad E.

Patent number: 9539997Abstract: A system and method are disclosed for controlling a power split in a hybrid powertrain having an engine and a motor. According to at least one aspect of the present disclosure, the method includes selecting a displaced fuel consumption value for the engine based on a quantity of available reclaimed energy in a battery, where the displaced fuel consumption value favors using the quantity of available reclaimed energy at relatively high load conditions, operating the engine at a condition based on the displaced fuel consumption value to generate engine power to meet at least a portion of a power demand, and operating the motor to generate motor power sufficient to supply a remaining power demand not met by the engine power. The system includes a controller configured to perform the operations of the method.Type: GrantFiled: July 29, 2014Date of Patent: January 10, 2017Assignee: Cummins Inc.Inventors: Zhen Sun, Morgan MacKenzie Andreae, Martin T.
