PURPOSE: A method for preventing the movement of a vehicle in case of parking on a slope road is provided to prevent the vehicle from rolling unintentionally, by judging the slope road and minute vehicle speed generation at the same time. CONSTITUTION: The possibility of N shift entry is judged(S140). An N shift is performed(S150). After the N shift is maintained for fixed time, a vehicle speed sensor is monitored(S160). The generation of a vehicle speed during the monitoring process is judged(S170). The vehicle is controlled in a standby state and maintains the N shift at the same time(S180). [Reference numerals] (AA) P/R/D/M shift; (BB) N shift; (CC) Drive; (DD) Stop; (EE) Speed reduction; (FF) Try to park from at P shift to at N shift; (S110) Position of vehicle gear shift before turning off the ignition is N or P/R/D/M; (S111) When driving→N shift, below a random speed(5KPH)→P shift; (S120) After turning off the ignition, check the driving and parking state of a vehicle * check whether the N shift is recognized when driving or parking; (S121) Maintain the N shift; (S130) Maintain the N shift (maintain the N shift by pulling an parking release cable); (S140) Is the N shift entry possible?; (S141) Display a warning message to a driver about the possibility of falling backward of a vehicle, an automatic transmission of N shift→P shift; (S150) Transmission to the N shift(enter the N shift by pulling an parking release cable); (S160) Monitor a vehicle speed sensor at a random time after maintaining the N shift; (S170) Check whether there is any problem with regard to the entry of the N shift after checking the speed (Is the maintenance of the N shift possible?); (S180) Maintain the N shift & sleep mode status |
