A new dynamic hysteresis assessment process for hybrid vehicles based on an optimal power loss control strategy

摘要

A hybrid control system comprises a power loss (PL) determination module, a hysteresis estimation module, and a mode determination module. The PL determination module determines a power loss of a hybrid drivetrain based on an engine speed, a motor speed, and a vehicle speed. The hysteresis estimation module determines an average power loss of the hybrid drivetrain based on the power loss and determines a hysteresis power loss of the hybrid drivetrain based on the average power loss. The mode determination module selects an operation mode of the hybrid drivetrain based on the hysteresis power loss. The hybrid control system controls the hybrid drivetrain based on the operation mode.
