  • Control device for vehicular engine having an automatic transmission and its control method
    Patent number: 5403245
    Abstract: A control device for a vehicular engine having an automatic transmission comprising: an inner cylinder pressure sensor for detecting a pressure in a combustion chamber of an engine; means for detecting an output of the inner cylinder pressure sensor at a predetermined crank angle; means for calculating an output torque of the engine based on the detected output of the inner cylinder pressure sensor; means for detecting a rotation speed of an engine; means for detecting a rotation speed of an output shaft of a torque convertor; means for calculating a speed ratio of the rotation speed of the output shaft of the torque converter as compared to the rotation speed of the engine; means for calculating a torque of an output shaft of an automatic transmission based on the output torque of the engine, the rotation speed of the engine, the rotation speed of the output shaft of the torque converter and the speed ratio; and control means for controlling at least one of the output torque of the engine and a hydraulic pre
