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.

First claim

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,
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,
wherein, when a shift signal is transmitted by 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, and
wherein when another 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 another shift signal and performs a control of the transmission according to the another shift signal.

2. The method of claim 1 , wherein, when another shift signal is transmitted after the transmitting of the shift signal is stopped, the TCU accepts the another shift signal transmitted after the transmitting of the shift signal is stopped and performs a control of the transmission according to the another shift signal transmitted after the transmitting of the shift signal is stopped.

3. The method of claim 1 , wherein the shift operation device includes one of a button type, a dial type, and a lever type.

4. A method for transmitting shift signals of an electronic shift system including a transmission control unit (TCU), the method comprising:
receiving, by the transmission control unit (TCU), the shift signals transmitted by a shift operation device, wherein the shift signals are generated and individually separated according to shifting stages by the shift operation device at a time of operation of the shift operation device which is configured so that one shift stage and one shift signal among the shift signals are matched one to one; and
performing, by the TCU, a shifting of a transmission, according to the received shift signals,
wherein, when a shift signal among the shift signals which are individually separated according to the shifting stages is received, 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,
wherein, when a shift signal is transmitted by the operation of the shift operation device when a shift condition is not satisfied, the TCU is configured for forcibly stop the transmitting of the shift signal after the predetermined time period elapses, and
wherein when the TCU receives another shift signal within the predetermined time period after the transmitting of the shift signal is stopped when the shift condition is satisfied, the TCU accepts the another shift signal and performs a control of the transmission according to the another shift signal.

5. A method for transmitting shift signals of an electronic shift system including a shift operation device, the method comprising:
transmitting, by the 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 is configured to transmit the shift signals which are each individually separated according to shifting stages; and
stopping, by the shift operation device, the transmitting of the shift signal according to a control of the TCU after a predetermined time period determined by TCU's counting a time from a point of time of transmitting the shift signal generated at the time of operating the shift operation device when a shift signal among the shift signals which are individually separated according to the shifting stages is received by the TCU,
wherein, when the shift operation device transmits a shift signal when a shift condition is not satisfied, the shift operation device is configured to stop transmitting of the shift signal according to a control of the TCU after the predetermined time period elapses, and
wherein the shift operation device transmits another shift signal within the predetermined time period after stopping the transmitting of the shift signal when the shift condition is satisfied, so that the TCU accepts the another shift signal and performs a control of a transmission according to the another shift signal.
