  • System and method for engine driveline disconnect during regeneration in hybrid vehicles
    Patent number: 10562519
    Abstract: A system and method for operating a hybrid vehicle having an engine and an eMachine coupled by a clutch using a hybrid controller is presented. The method determines an idle fuel rate of the engine, determines a hybrid efficiency index for the hybrid vehicle, determines an expected energy storage rate increase for an operating condition where the engine is decoupled from a vehicle transmission using said clutch, multiplies the expected energy storage rate increase by the hybrid efficiency index to determine an expected fuel rate reduction of the engine in the operating condition; and decouples the engine from the vehicle transmission using the clutch if the expected fuel rate reduction is greater than the idle fuel rate.
    Type: Grant

  • System and method for optimizing hybrid vehicle battery usage constraints
    Patent number: 9555719
    Abstract: A hybrid system including a hybrid control module for operating the hybrid system to as to have its energy storage device meet a predetermined service life metric is disclosed. The hybrid control module stores experimental information indicative of the impact of certain usage parameters on the service life of the energy storage device, monitors the actual usage parameters observed during operation of the hybrid system, and dynamically determines a maximum operating temperature for the energy storage device in order to increase or decrease its utilization by the hybrid system.
