Abstract

A drive force control system for a vehicle configured to change a torque to propel a vehicle certainly in a required amount by controlling output torques of an engine and a motor. A controller is configured to: calculate a required amount of change in synthesized torque of an engine torque and a motor torque; calculate a required amount of change in the engine torque and a required amount of change in the motor torque based on the required amount of change in the synthesized torque; select one of the engine and the motor whose torque will be changed further than a limit value; and adjust the torque of the selected prime mover by a counter torque.
