An evolutionary control for a subject such as an engine installed in a vehicle is conducted by the steps of: selecting coefficients, as genes, affecting the control characteristics of the control system; creating plural control units as chromosomes, each being constituted by plural genes; expressing the genes of each chromosome as control characteristics by controlling the subject using the control system having the control characteristics; selecting at least one chromosome from the created chromosomes based on the control characteristics expressed by the genes in view of the user's preference; and causing the at least one chromosome to evolve using a genetic algorithm, thereby obtaining control characteristics suitable for the user. In this method, the characteristics of the product can effectively be adjusted after its purchase based on the user's preference.

[ What is claimed is:] [1.] A method for controlling performance of a motor used by a user, which motor is operable by causative signals, the performance of which motor is indicatable by indicative signals, said motor being controlled by a control system provided with said motor and comprising:(i) a base value output unit to output a base value of a causative signal when receiving pre-selected signals, said base value output unit preventing said motor from malfunctioning; and(ii) an evolution unit comprising a control module programmed to output and add a compensation value to the base value of the causative signal when receiving pre-selected signals, wherein the input-output relationship of the control module is regulated by coefficients; said evolution unit provided with a genetic algorithm unit programmed to select fitted coefficients based on a selection signal when using coefficients as genes, wherein the selected fitted coefficients replace the coefficients used in the control module to update its input-output relationship;said method being conducted without discontinuing performance of said motor comprising the steps of:(a) outputting the causative signals from the base value;(b) outputting and adding a compensation value to the base value of the causative signal to operate said motor;(c) selecting fitted coefficients by the genetic algorithm unit based on a selected selection signal, said selection signal inputted by the user in response to the performance of said motor based on its indicative signals while said motor is in operation; and(d) replacing the coefficients used in the control module to update its input-output relationship to control said motor whereby said control system is updated on a real time basis to adapt performance of said motor to the user.
