ABSTRACT:
A method and system to capture energy during regenerative braking while managing driveline disturbances by controlling locking and unlocking of a torque-converter clutch based upon operator input, typically throttle position or accelerator pedal position, vehicle speed, and engine load is offered. The exemplary vehicle has an engine, a torque converter with a clutch, and a transmission device. Vehicle kinetic energy is transmittable to an electrical machine using the transmission device and the torque converter. It includes monitoring an operator demand for power, engine operating speed, and, engine load; and, actuating the locking clutch for the torque converter based upon the operator demand for power, the engine operating speed, and, the engine load.
