US Patent 7983826 Control apparatus and control method for drive source

Static demand engine torque set in a static torque setter is converted into dynamic demand engine torque in a converter using an engine model C (s) represented by a first-order lag function. A time constant T of engine model C (s) is calculated by a time constant calculator. The time constant calculator calculates time constant T in accordance with the static demand engine torque set in the static torque setter and dynamic demand engine torque set in a dynamic torque setter. The dynamic demand engine torque set in the dynamic torque setter is added to the dynamic demand engine torque converted from the static demand engine torque in the converter.
