Abstract
A control method and system for preventing misoperation of a shift lever of a vehicle are provided. In particular, when a driver manipulates the shift lever to select an automatic transmission mode or a manual transmission mode, shifting into an unintended mode attributable to misoperation is prevented. Therefore, the control method and system improve reliability in manipulating the shift lever and provide a safe driving environment to a driver.
Claims14
A control method for preventing misoperation of a shift lever of a vehicle, comprising:
- determining, by a controller, whether the shift lever is shifted from an N range, which is a neutral mode, or from a park (P) range, which is a parking mode, to a drive (D) range;
- determining, by the controller, whether the shift lever maintains the D range for more than a preset period of time;
- determining, by the controller, whether shifting from the D range, which is an automatic transmission mode, into a manual (M) range, which is a manual transmission mode, is attempted by manipulation of the shift lever;
- receiving, by the controller, information regarding whether a manual mode switch button is manipulated in response to determining that shifting from the D range to the M range is attempted;
- permitting, by the controller, a shift range to be switched from the D range to the M range in response to receiving information indicating that the manual mode switch button is manipulated;
- outputting, by the controller, a misoperation signal when the shift lever remains in the D range for less than the preset period of time;
- and
- preventing, by the controller, the shift range from being switched from the D range to the M range when the misoperation signal is output.
A system for preventing misoperation of a shift lever of a vehicle, comprising:
- a manual mode switch button, disposed on a shift lever side, configured to output a signal when being manipulated;
- a position check module configured to determine a shift range based on a position of the shift lever;
- and
- a shifting controller configured to permit the shift range to be switched from a drive (D) range to a manual (M) range when a signal indicating that the shift lever is shifted from the D range to the M range is input by the position check module and when the signal is input as a result of manipulation of the manual mode switch button,
- wherein the shifting controller includes a misoperation check module configured to determine whether the shift lever remains in the D range for more than a preset period of time when the position check module determines that the shift lever is shifted from a neutral (N) range or a park (P) range to the D range, and
- wherein the shifting controller is configured to permit the shift range to be switched from the D range to the M range when information indicating that the shift lever maintains the D range for more than the preset period of time is input by the misoperation check module.
