Abstract
Abstract In an engine output control apparatus including an engine output control means for controlling the output of an engine, an electric motor for driving the means, and a motor control means for controlling the electric motor commensurate with the state of operation of an accelerator pedal, a method of controlling the output of the engine, comprising: obtaining an engine torque target (Te) commensurate with the state of operation of the accelerator pedal; calculating a target amount of engine control (θt) based on the engine torque target (Te) and an engine speed (Ne); and controlling the engine output control means by the electric motor so as to meet with the target amount of engine control (θt).

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
131 words
A method of controlling output of an engine using an engine output control apparatus including an engine output control means for controlling the output of the engine, an electric motor for driving the control means, motor control means for controlling the electric motor commensurate with a state of operation of an accelerator pedal, and means for determining the engine speed, said method comprising the steps of: calculating a target amount of intake air per engine rotation representative of a target engine torque based on the state of operation of the accelerator pedal; calculating a target engine control amount from said target amount of intake air per engine rotation and the engine speed; and controlling the engine output control means using the electric motor in accordance with the target engine control amount.
Claim 2
Independent Claim
131 words
A method of controlling output of an engine using an engine output control apparatus including an engine output control means for controlling the output of the engine, an electric motor for driving the control means, motor control means for controlling the electric motor commensurate with a state of operation of an accelerator pedal, and means for determining the engine speed, said method comprising the steps of: calculating a target amount of intake air per engine rotation representative of a target engine torque based on the state of operation of the accelerator pedal; calculating a target engine control amount from said target amount of intake air per engine rotation and the engine speed; and controlling the engine output control means using the electric motor in accordance with the target engine control amount.
Claim 3
Dependent Claim
27 words
An engine output controlling method according to claim 1, wherein the state of operation of said accelerator pedal is the position of operation of said accelerator pedal.
