DRIVING FORCE CONTROL DEVICE FOR HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve overall efficiency by obtaining target engine torque from target drive torque computed out of an accelerator stepping quantity and the like and generating torque of a motor computed out of a battery charged state, and obtaining target motor torque out of difference portion between the target drive torque and the engine torque estimated value. SOLUTION: For driving force control of a hybrid vehicle running by the driving force of an engine and/or a motor, a controller 16 computes target drive torque based on the detected signals of an accelerator sensor 22 and a vehicle speed sensor 24. Generating torque by a motor is computed based on the detected signal of a charged state detecting device 26 detecting the charged state of a battery 15 giving and receiving power against the motor. The engine is controlled by setting a torque value attaining the target drive torque and the generating torque to be target engine torque, and the motor is controlled by setting the difference portion between the target drive torque and the engine torque estimated value to be target motor torque.
