System and method for controlling a hybrid power propulsion device for constant four-wheel drive mode operation

摘要

The system has an electrical motor unit (3a) and thermal motor unit (5) independently driving front powered axle (12) and a back powered axle (13) of a motor vehicle (1). A determination unit (9) determines a total torque set from the demand of a driver, and an optimization unit (11) optimizes an operating point for dynamically determining the torque to be applied to each of the powered axle and optimizing the function of a hybrid powertrain (2) based on the driveability demanded by the driver and the rolling conditions. An independent claim is also included for a method for controlling a hybrid powertrains of a motor vehicle having a four driving wheel.
