Shift Control System Of Hybrid Vehicle With Automatic Transmission And Method Thereof
First Claim
1. A shift control system of a hybrid vehicle with an automatic transmission, comprising:
- a fuzzy function calculator that receives an accel position sensor (APS) signal that is an input variable, and outputs a severity value by determining a driver'"'"'s driving severity value through a plurality of fuzzy rules including a fuzzy function for the APS signal;
a sporty degree calculator that is electrically connected with the fuzzy function calculator and determines a sporty degree corresponding to the severity value; and
a mode determiner that is electrically connected with the sporty degree calculator and determines whether an engine operates in accordance with the sporty degree.

8. A control method of a shift control system of a hybrid vehicle, comprising,
determining a sporty degree by finding a driver'"'"'s driving severity value on the basis of a plurality of fuzzy rules for accel position sensor (APS) signals that are detected input variables; -
ascertaining whether the determined sporty degree is larger than a first reference value; ascertaining whether a vehicle speed is higher than a reference vehicle speed, when the sporty degree is larger than the first reference value; and starting an engine in advance, when the vehicle speed is higher than the reference vehicle speed. - View Dependent Claims (9, 10, 11, 12, 13, 14)
