Engine controlling apparatus and method for a car

摘要

An engine output is controlled by controlling an electronically controlled throttle valve based upon an objective engine torque that is set by referring to an engine torque map having data of an accelerator opening degree and an engine rotating speed. A torque correction rate of the objective engine torque is calculated by a surface interpolation with each direction interpolation of a speed change ratio for a transmission and the engine rotating speed based upon a map having the speed change ratio and the engine rotating speed as lattice axes. The objective engine torque is corrected corresponding to the torque correction rate thereof.
