ELECTRONIC CONTROLLER OF AUTOMATIC TRANSMISSION

PROBLEM TO BE SOLVED: To realize adequate multiple shift control in an electronic controller for controlling an automatic transmission according to a program on the basis of an object-oriented idea. SOLUTION: A shift controlling portion SQM informs a domain controller provided for each driving component (linear solenoid valve SLN, SLU, SLT) of a transmission pattern ID indicating a switch from which shift stage to which shift stage using a driving control requiring message. In the case of the multiple shift, a multiple shift pattern ID indicating progression degree of the current shift control as well as the shift pattern ID are informed using the driving control requiring message, and based on this message, adequate shift control process for the driving components are performed. Therefore, independency and reclamation of the program are improved, and simultaneously the plurality of driving components required for the shift control can be at an adequate timing even in the case of the multiple shift.
