Abstract—From the perspective of vehicle driving, the relation between driveline efficiency and fuel efficiency is a trade-off. Moreover, there are differences in each driver’s preference in the ranges of driveline efficiency and fuel efficiency. For these reasons, the optimization between driveline efficiency and fuel efficiency is applied considering personal driving characteristics. Study using a Continuously Variable Transmission (CVT) control algorithm has advantageous because continuous gears have a lot of freedom for control. Therefore, the Target Probability, which is related to the driving characteristics, is applied to the CVT gear shifting control algorithm based on a CVT vehicle model and verified.
Index Terms—Controller, CVT, driveline efficiency, economy mode, fuel efficiency, modeling, personal driving characteristic, sporty mode.
