Shifting control for automatic power transmission with learning shifting pattern model and selecting shifting pattern model from closed vehicular driving pattern

A control system for controlling transmission gear shifting for an automatic transmission of an automotive vehicle, said control system comprising:

• first means for monitoring a plurality of vehicle driving parameters to provide signals indicative of parameter data representing types and values of monitored vehicle driving parameters;
• second means for shifting a gear ratio of said automatic transmission in one of first and second gear shift modes according to first and second shift schedule maps respectively;
• third means for manually switching between said first and second gear shift modes;
• fourth means, including a matrix provided with a plurality of memory addresses which are variable from first to second address values in response to input of said parameter data, said fourth means being responsive to signals from said first and third means for storing parameter data in corresponding addresses according to types and values of parameter data to provide a data pattern which represents one of said first and second gear shift modes and for determining relations between first and second address values of adjacent addresses which include variables to which a preselected value is added when address values between adjacent addresses are the same and from which said preselected value is subtracted when address values between adjacent addresses are different from each other;
• fifth means responsive to signals from said first means indicative of vehicle driving parameters to input parameter data thereof to corresponding addresses for modifying each address value based on magnitudes of variables between adjacent addresses determined by said fourth means to provide a data pattern corresponding to a data pattern stored in addresses provided by said fourth means to determine a corresponding one of said first and second gear shift modes and for providing a signal indicative thereof;
• and
• sixth means associated with said second means for changing between said first and second shift modes based on said signal from said fifth means.
