Abstract
A hybrid system or a control method for a vehicle having a first set of road wheels and a second set of road wheels is disclosed. The system comprises an engine controller for receiving a torque request for an engine driving torque and combining an idle speed torque and the engine driving torque to generate an engine torque command signal. An engine, drivingly coupled with the first set of road wheels, applies a first driving torque to the first set of road wheels in response to the engine torque command signal. A hybrid controller is in communication with the engine controller. The hybrid controller generates the torque request and a motor torque command signal taking into account a creep torque portion of the first driving torque and a desired driving torque during starting the vehicle from standstill. A motor is drivingly coupled with the second set of road wheels. The motor applies a second driving torque to the second set of road wheels in response to the motor torque command signal.
