Abstract
An engine controlling system for a vehicle suitable for use with an automobile. When a running condition change-over means develops a constant speed running designating signal, an aimd torque calculating means calculates an aimed output torque of an engine of the vehicle in accordance with an aimed speed, but when the running condition change-over means develops an accelerated running designating signal, the aimed torque calculating means calculates an aimed output torque of the engine in accordance with an aimed acceleration. Meanwhile, an engine output torque detecting means calculates an output torque of a torque converter in accordance with characteristics of the torque converter and an engine rotational speed detection signal detected by an engine rotational speed detecting means and outputs the output torque as a measured value of the output power of the engine. A control amount setting means sets the control amount of an engine output adjusting means so that the engine output torque detected by the engine output torque detecting means may be equal to the aimed torque, and the engine output adjusting means adjusts the output of the engine by control of an engine output contro…
