Method for transmitting shift signal of electronic shift system

Abstract

A method for transmitting a shift signal of an electronic shift system, may include transmitting the shift signal generated at the time of operating a shift operation device, wherein the shift operation device is configured so that one shift stage and one shift signal are matched one to one and transmits shift signals which are each individually separated according to the shift stage.

What is claimed is: 
     
         1 . A method for transmitting shift signals of an electronic shift system, the method comprising:
 transmitting, by a shift operation device, a shift signal generated at a time of operating the shift operation device, to a transmission control unit (TCU), wherein the shift operation device is configured so that one shift stage and one shift signal among the shift signals are matched one to one and transmits the shift signals which are each individually separated according to shifting stages; and   performing, by the TCU, a shifting of a transmission, according to the transmitted shift signal.   
     
     
         2 . The method of  claim 1 , wherein, when the shift signals which are each individually separated according to the shifting stages are transmitted to the TCU, a signal of a selected one shift stage is transmitted to the TCU, and signals of remaining shifting stages which are not selected are not transmitted to the TCU. 
     
     
         3 . The method of  claim 1 , wherein, when a shift signal among the shift signals which are individually separated according to the shifting stages is transmitted within a predetermined time period, the TCU accepts the transmitted shift signal and performs a control of the transmission according to the one transmitted shift signal. 
     
     
         4 . The method of  claim 1 , wherein, when two or more shift signals among the shift signals which are individually separated according to the shifting stages are simultaneously transmitted to the TCU within a predetermined time period, the TCU accepts a shift signal transmitted last to the TCU and performs a control of the transmission according to the shift signal transmitted last to the TCU, and rejects remaining shift signals which are previously transmitted to the TCU. 
     
     
         5 . The method of  claim 1 , wherein, when a shift signal among the shift signals which are individually separated according to the shifting stages is transmitted, the TCU counts a time from a point of time of transmitting the shift signal generated at the time of operating the shift operation device and stops the transmitting of the shift signal after a predetermined time period elapses. 
     
     
         6 . The method of  claim 5 , wherein, when another shift signal is transmitted after the transmitting of the shift signal is stopped, the TCU accepts the another shift signal and performs a control of the transmission according to the another shift signal. 
     
     
         7 . The method of  claim 6 , wherein, when a shift signal is transmitted by the operation of the shift operation device when a shift condition is not satisfied, the transmitting of the shift signal is forcibly stopped after the predetermined time period elapses. 
     
     
         8 . The method of  claim 7 , wherein when the other shift signal is transmitted within the predetermined time period after the transmitting of the shift signal is stopped when the shift condition is satisfied, the TCU accepts the other shift signal and performs a control of the transmission according to the other shift signal. 
     
     
         9 . The method of  claim 1 , wherein the shift operation device includes a button type, a dial type, and a lever type.
