摘要： A control device for an internal combustion engine and a continuously variable transmission of a vehicle according to the present invention comprises the continuously variable transmission disposed between the internal combustion engine and driving wheels and enables controlling the output of the internal combustion engine. In particular, objective driving torque Tet is set according to driving torque Td applied to a vehicle, driving torque correcting amount T.sub.IV which serves as a first running resistance of the vehicle according to vehicle acceleration, transmission torque fluctuation correcting amount Tcv which serves as a second running resistance due to being consumed in the transmission operation mode of the continuously variable transmission, and vehicle body correcting torque Tv, which is necessary for eliminating a deviation .DELTA.v between an objective vehicle speed Vt and an actual vehicle speed Vc, required for eliminating this deviation .DELTA.v to control the output of the internal combustion engine with this objective driving torque. Accordingly, the internal combustion engine can be controlled with the output corresponding to a value of the objective driving torque Tet set by selectively using an optimum torque correcting amount depending on driving conditions. This results in elimination of slip of a transmission steel belt caused by excessive output and shock in the transmission operation.

摘要： A control device for an internal combustion engine and a continuous variable transmission which enables well-responsible transmission control to be carried out at a proper transmission rate without increasing the transmission shock. When engine power corresponding to an engine power torque corrected amount is changeable, then an intake air flow adjusting unit is controlled in response to a corrected engine power torque corrected amount. On the contrary, when the corrected engine power torque corrected amount is not changeable, the amount corrected engine power torque corrected is restricted within a range where the engine power can be changed.

摘要： Described herein is a drive-by-wire vehicle engine output control system. The system permits good-response acceleration by a driver's simple and reasonable operation, i.e., by operating an accelerator pedal and also a prompt response even when a sudden load change occurs. Further, the system permits precise speed control by simple equipment even when the deviation of a vehicle speed from a target vehicle speed is large. Output changes of an engine can be controlled within a permissible output change range by (a) comparing a target autocruise engine output with an acceleration demanding ending output, choosing the larger engine output and then controlling the engine to give the larger engine output, (b) controlling the engine to achieve a target autocruise engine output obtained from a speed correction torque and a running load torque or (c) limiting an engine control quantity on the basis of a permissible output change value.
