An engine control system reduces thermal deterioration of a torque converter. Maximum torque down control is provided, using simple processing and a minimum number of required signals, to reduce thermal deterioration. A maximum fuel injection amount QFULL is reduced when vehicle speed is less than a predetermined value that is close to zero, thereby lowering maximum engine torque. Also, the presence or absence of an abnormal vehicle speed sensor is diagnosed and maximum engine torque is also lowered during occurrence of an abnormality. |
