Abstract

In a vehicle including a shift-by-wire (SBW) transmission which may be parked in the neutral gear position of the transmission, method for controlling parking thereof includes determining whether the vehicle is in a situation in which neutral parking is required according to sensor information, when the vehicle is stopped, outputting first information configured to get a confirmation on whether a driver intends to perform the neutral parking from the driver, when the controller concludes that the vehicle is in the situation in which the neutral parking is required and when a park (P) gear position is input or an ignition of the vehicle is turned off, and controlling the SBW transmission to shift to a neutral (N) gear position, when there is an agreement input as a response to the first information.

First claim

What is claimed is:

1. A method for controlling parking of a vehicle including a shift-by-wire (SBW) transmission, the method comprising:
determining, by a controller, whether the vehicle is in a situation in which neutral parking is required according to sensor information, when the vehicle is stopped;
outputting, by the controller, first information configured to get a confirmation on whether a driver intends to perform the neutral parking from the driver, when the controller concludes that the vehicle is in the situation in which the neutral parking is required and when a park (P) gear position is input or an ignition of the vehicle is turned off; and
controlling, by the controller, the SBW transmission to shift to a neutral (N) gear position, when there is an agreement input as a response to the first information.

2. The method of claim 1 , further including:
outputting, by the controller, second information configured to indicate that the N gear position is maintained even after the ignition is turned off, when the first information is output as the P gear position is input, and there is the agreement input.

3. The method of claim 1 , further including:
outputting, by the controller, third information configured to indicate that the SBW transmission shifts to the N gear position, when the first information is output as the ignition is turned off without input of the P gear position, and there is the agreement input.

4. The method of claim 1 , further including:
controlling, by the controller, the SBW transmission to shift to the P gear position, when the first information is output as the ignition is turned off without input of the P gear position, and there is a disagreement input as the response to the first information.

5. The method of claim 4 , further including:
when there is the disagreement input, outputting a message informing that the transmission has shifted to the P gear position through the input/output unit.

6. The method of claim 1 , wherein the situation in which the neutral parking is required includes at least one of a case in which the vehicle is parked adjacent to peripheral vehicles parked in parallel in one direction such that a longitudinal direction of the vehicle is parallel to the one direction, a case in which the vehicle is parked outside parking lines to block an exit direction of peripheral vehicles parked inside the parking lines, or a case in which the vehicle is parked such that the longitudinal direction of the vehicle is parallel to a predetermined length or more of a parking line.

7. The method of claim 1 , further including:
before the determining whether the vehicle is in the situation in which the neutral parking is required,
determining, by the controller, whether the parking of the vehicle is underway or whether the parking is expected to be performed; and
activating, by the controller, at least one sensor configured to provide the sensor information, upon determining that parking is underway or that parking is expected to be performed.

8. The method of claim 7 , wherein, in the determining whether the parking of the vehicle is underway or whether the parking is expected to be performed, the controller concludes that the parking is underway or that the parking is expected to be performed, when a current gear position of the SBW transmission is a drive (D) gear position or a reverse (R) gear position and a vehicle speed is equal to or lower than a predetermined speed, when a current position of the vehicle detected by a navigation system is close to a destination of the vehicle or enters a parking lot, when a Global Positioning System (GPS) signal is lost, or when a command configured to activate the at least one sensor is input.

9. The method of claim 7 , wherein the at least one sensor includes at least one of an ultrasonic sensor, a camera or a radar.

10. A non-transitory computer readable recording medium having recorded thereon a program to execute the method of claim 1 .

11. A vehicle comprising:
a shift-by-wire (SBW) transmission;
at least one sensor;
an input/output unit; and
a controller electrically connected to the SBW transmission, the at least one sensor and the input/output unit and configured to determine whether the vehicle is in a situation in which neutral parking is required according to sensor information provided by the at least one sensor, when the vehicle is stopped, to output first information configured to get a confirmation on whether a driver intends to perform the neutral parking from the driver through the input/output unit, when the controller concludes that the vehicle is in the situation in which the neutral parking is required and when a park (P) gear position is input or an ignition of the vehicle is turned off, and to control the SBW transmission to shift to a neutral (N) gear position, when there is an agreement input as a response to the first information.

12. The vehicle of claim 11 , wherein the controller is configured to output second information configured to indicate that the N gear position is maintained even after the ignition is turned off through the input/output unit, when the first information is output as the P gear position is input, and there is the agreement input.

13. The vehicle of claim 11 , wherein the controller is configured to output third information configured to indicate that the SBW transmission shifts to the N gear position through the input/output unit, when the first information is output as the ignition is turned off without input of the P gear position, and there is the agreement input.

14. The vehicle of claim 11 , wherein the controller is configured to control the SBW transmission to shift to the P gear position, when the first information is output as the ignition is turned off without input of the P gear position, and there is a disagreement input as the response to the first information.

15. The vehicle of claim 14 , wherein when there is the disagreement input, the controller is configured to output a message informing that the transmission has shifted to the P gear position through the input/output unit.

16. The vehicle of claim 11 , wherein the situation in which the neutral parking is required includes at least one of a case in which the vehicle is parked adjacent to peripheral vehicles parked in parallel in one direction such that a longitudinal direction of the vehicle is parallel to the one direction, a case in which the vehicle is parked outside parking lines to block an exit direction of peripheral vehicles parked inside the parking lines, or a case in which the vehicle is parked such that the longitudinal direction of the vehicle is parallel to a predetermined length or more of a parking line.

17. The vehicle of claim 11 , wherein the controller is configured to determine whether parking of the vehicle is underway or whether the parking is expected to be performed, and to activate the at least one sensor, upon determining that the parking is underway or that the parking is expected to be performed.

18. The vehicle of claim 17 , wherein the controller is configured to determine that the parking is underway or that parking is expected to be performed, when a current gear position of the SBW transmission is a drive (D) gear position or a reverse (R) gear position and a vehicle speed is equal to or lower than a predetermined speed, when a current position of the vehicle detected by a navigation system is close to a destination of the vehicle or enters a parking lot, when a Global Positioning System (GPS) signal is lost, or when
