ABSTRACT:
In a control system for controlling a gear ratio of a multi-step geared or continuously variable automatic transmission, the driver's intention to decelerate is inferred by carrying out a first fuzzy reasoning using a degree of throttle opening or the like and then the target gear ratio is determined by carrying out a second fuzzy reasoning using parameters including the inferred driver's intention to decelerate. The first fuzzy reasoning is carried out using fuzzy production rules classified by operating conditions such as a road profile and a vehicle speed. The inferred driver's intention to decelerate is canceled if braking is discontinued. Thus the control ascertain the intention of the driver and is thus possible to achieve sophisticated shift scheduling well matched to the sensibilities of the driver.
