Method of controlling vehicle washing mode for vehicle equipped with shift-by-wire shifting device

Abstract

A method of controlling a vehicle washing mode for a vehicle equipped with shift-by-wire shifting device, may include performing an N-range-off determining step that determines whether a shift lever is in an N-range when an engine stops, performing an ACC determining step that determines whether the vehicle is in an ACC state, and performing a shifting step that shifts a P-range state of a transmission to a N-range state thereof by operating an actuator, when the N-range-off determining step determines that the shift lever is in the N-range when the engine was stopped, and when the ACC determining step determines that the vehicle is in the ACC state.

What is claimed is: 
     
         1 . A method of controlling a vehicle washing mode for a vehicle equipped with shift-by-wire shifting device, the method comprising:
 performing an N-range-off determining step that determines whether a shift lever is in an N-range when an engine stops;   performing an ACC determining step that determines whether the vehicle is in an ACC state; and   performing a shifting step that shifts a P-range state of a transmission to an N-range state thereof by operating an actuator, when the N-range-off determining step determines that the shift lever is in the N-range when the engine was stopped, and when the ACC determining step determines that the vehicle is in the ACC state.   
     
     
         2 . The method as defined in  claim 1 , further comprising:
 performing a TCU (Transmission Control Unit)-off checking step that checks whether a controller that controls the transmission is turned off is operated, after the ACC determining step and before performing of the shifting step, and   performing the shifting step when the TCU-off checking step determines that the controller that controls the transmission is turned off.   
     
     
         3 . The method as defined in  claim 2 , wherein the N-range state of the transmission is maintained for a predetermined time for vehicle washing, and then after the predetermined time passes, the controller automatically performs shifting the N-range state to the P-range state and after a predetermined time passes again, cuts the power when there is no operation to the vehicle. 
     
     
         4 . The method as defined in  claim 2 , wherein the N-range state of the transmission is maintained for a predetermined time for vehicle washing and the power is cut with the N-range state of the transmission maintained. 
     
     
         5 . The method as defined in  claim 2 , wherein the N-range state of the transmission is maintained for a predetermined time for vehicle washing and a current state of the vehicle is maintained. 
     
     
         6 . A method of controlling a vehicle washing mode for a vehicle equipped with shift-by-wire shifting device, which automatically implement a P-range state in a transmission when an engine is stopped in an N-range state of a shift lever, the method comprising:
 shifting the transmission from the P-range state to an N-range state thereof by operating an actuator, when the engine is stopped, an ACC state is implemented in the vehicle, and the shift lever is in the N-range state when the engine is stopped.   
     
     
         7 . The method as defined in  claim 6 , further comprising:
 shifting the transmission from the P-range state to the N-range state, by operating the actuator, when the engine stops, the ACC state is implemented in the vehicle, the transmission is not in the N-range state when the engine is stopped, and a controller is turned off.   
     
     
         8 . The method as defined in  claim 7 , wherein the N-range state of the transmission is maintained for a predetermined time for vehicle washing, and then after the predetermined time passes, the controller automatically performs shifting the N-range state to the P-range state and after a predetermined time passes again, cuts the power when there is no operation to the vehicle. 
     
     
         9 . The method as defined in  claim 7 , wherein the N-range state of the transmission is maintained for a predetermined time for vehicle washing and the power is cut with the N-range state of the transmission maintained. 
     
     
         10 . The method as defined in  claim 7 , wherein the N-range state of the transmission is maintained for a predetermined time for vehicle washing and a current state of the vehicle is maintained.
