Shift control system of hybrid vehicle with automatic transmission and method thereof |
摘要 |
A shift control system of a hybrid vehicle with an automatic transmission may include a fuzzy function calculator that receives an accel position sensor (APS) signal that may be 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 may be electrically connected with the fuzzy function calculator and determines a sporty degree corresponding to the severity value, and a mode determiner that may be electrically connected with the sporty degree calculator and determines whether an engine operates in accordance with the sporty degree. |

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; wherein the sporty degree calculator includes a configuration that divides the severity values for the fuzzy rules by severity values for eco-, medium, and sporty traveling states, and determines the sporty degree by using a center of an area obtained by summing up the areas for the minimum values in the severity values for eco-, medium and sporty traveling states; and wherein the mode determiner includes a configuration that starts the engine in advance to facilitate acceleration of the engine, if acceleration is required, when the sporty degree is above a first reference value and the vehicle speed is above a reference vehicle speed. |
