VEHICLE AUTOMATIC TRANSMISSION CONTROL SYSTEM |
摘要 |
A system for controlling automatic transmissions equipped a motor vehicle utilizing fuzzy logic. In the system, fuzzy production rules have been prepared based upon an expert driver's judgments and operation made on a vehicle with a manually shifted transmission. Various operating conditions including opening degree of a throttle valve and road speed of the vehicle are detected and from the detected value, various predictions are made such as an appropriateness of vehicle response to a gearshift intended by the driver and engine output change that would occur should the transmission be shifted to a given gear. These measured or estimated value are put on a common scale named universe of discourse and membership values degree of the aforesaid rules are successively calculated. Among the rules, one rule is finally selected and according to a gear position indicated in the selected rule, the current gear is shifted up or down or is held at the present position. |
