Abstract:
A hybrid system for a vehicle having a first set of road wheels and a second set of road wheels, comprising:an engine controller for receiving a torque request for an engine driving torque (vRTRQe) and combining an idle speed torque and the engine driving torque (vRTRQe) to generate an engine torque command signal; an engine drivingly coupled with the first set of road wheels to apply a first driving torque to the first set of road wheels in response to the engine torque command signal; a hybrid controller, in communication with the engine controller, for generating the torque request and a motor torque command signal taking into account a creep torque portion (CREEP_TRQ) of the first driving torque applied to the first set of road wheels and a desired driving torque (tTRQ1) during starting the vehicle from standstill; and a motor drivingly coupled with the second set of road wheels to apply a second driving torque to the second set of road wheels in response to the motor torque command signal.
