METHOD AND DEVICE FOR AUTOMATIC CHANGE-SPEED GEARING CONTROL EXPLOITED FUZZY THEORY

摘要

When the state of the vehicle satisfies a certain set condition, to select a shift pattern according to a function of the set fuzzy theory so that the shift operation according to the exact state change of the vehicle can be made and to solve the problems caused by the frequent shift operation; A driving state determination unit for outputting a plurality of corresponding signals due to a change in position of mercury embedded in the plurality of U-shaped tubes according to the driving state of the vehicle; Connected to the driving state determining unit, the vehicle speed signal, the throttle opening signal, the shift stage signal, and the brake signal to determine the position of the current shift stage, compare the speed of the vehicle, and determine whether the state of the vehicle is driving downhill. If the vehicle is traveling downhill, the shifting operation may be performed according to a special shift pattern. If the vehicle is not traveling downhill, it is determined whether the vehicle is traveling on a sloped road, and the vehicle is traveling on a sloped road. In this case, the shifting operation may be performed according to a special shifting pattern. If the vehicle is not driving on a sloped road, it is determined whether the vehicle is driving on a curved road. If you are not driving on a curved road, check whether However, the shift control unit for controlling the shift operation to perform the shift operation according to a special shift pattern when driving on the uneven road, and to be shifted to the corresponding gear according to the control signal applied in connection with the shift control unit The present invention relates to an automatic shift control device and method using a fuzzy theory composed of an automatic shift unit.
