A method of preventing initial value learning by incorrect learning in the total control method between the shift control unit and the engine control unit

摘要

The present invention provides a method for preventing initial value learning by mis-learning when the ignition delay signal is not input after determining whether a predetermined control signal, for example, an ignition delay signal, is input from the shift control unit (TCU) to the engine control unit (ECU). A first step S1 of terminating the execution; A second step (S2) of detecting the engine speed when the ignition delay signal is input as a result of the determination in the first step (S1); A third step (S3) of detecting the engine speed in the second step (S2) and calculating a rate of change (a) of engine rotation based on the engine speed; A fourth step (S4) of determining whether the calculated change rate (a) of the engine rotation is smaller than the change rate of the normal rotation after calculating the change rate (a) of the engine rotation in the third step (S3); A fifth step (S5) of performing initial value learning and correction when the change rate (a) of the engine rotation is smaller than the change rate of the normal rotation as a result of the determination in the fourth step (S4); As a result of the determination in the fourth step S4, when the change rate a of the engine rotation is not smaller than the change rate of the normal rotation, the sixth step S6 performs only learning of the normal initial value.
