Abstract:
1. An engine torque control apparatus comprising: a continuously variable transmission comprising a torque converter and a transmission mechanism, wherein said transmission mechanism includes a primary pulley, a secondary pulley, and a belt for transmitting power from the primary pulley to the secondary pulley; an engine connected to an input shaft of said torque converter; an engine torque control section that controls torque output from said engine; discharged torque calculating means for calculating a discharged torque of at least one of said engine and said transmission; and rotational speed detecting means for detecting a rotational speed of said primary pulley, wherein said engine torque control section controls torque of said engine according to the discharged torque calculated by said discharged torque calculating means, wherein said discharged torque calculating means calculates a friction discharged torque produced by contact frictional force, generated when the pulleys sandwich the belt therebetween, wherein said engine torque control section controls torque of the engine based on the calculated friction discharged torque, wherein said discharged torque calculating means comprises inertia discharged torque calculating means for calculating an inertia discharged torque of said engine or said transmission, wherein said engine torque control section controls torque of said engine according to the inertia discharged torque calculated by said inertia discharged torque calculating means, and wherein said inertia discharged torque calculating means calculates an inertia discharged torque produced by rotation of said transmission mechanism according to the rotational speed detected by said rotational speed detecting means.
