ABSTRACT:
A system for controlling an internal combustion engine for motor vehicles equipped with an automatic transmission. In the system, engine torque is calculated from an engine speed and an engine load. Similarly, transmissible torque of the transmission is computed from an hydraulic pressure exerted on a gear clutch and a friction coefficient and an entire surface area of the clutch engageable with each other. The two torque values are then compared with each other and if it is found that the engine torque exceeds the transmissible torque, the engine torque is restricted to the transmissible torque. As a result, a shock or jolting caused by clutch slippage occurred at gear shifting or the like can be avoided and unpleasantness resulted to the vehicle occupant and undue wear to the clutch plates are thus prevented.
