Abstract

An apparatus for switching between driving modes of a vehicle with an automatic driving system, including: an input unit for receiving an input to switch from automatic driving mode to manual driving mode; a speed sensor for determining a current speed of the vehicle; a display unit on which a first indicator indicating a current speed of the vehicle when the vehicle is in an automatic driving mode is displayed; a pedal sensor for determining a current displacement distance of an accelerator pedal; a controller for determining a virtual speed according to the current distance displacement of the accelerator pedal when an input is received that requests switching of the automatic driving mode of the vehicle to a manual driving mode if the vehicle is in the automatic driving mode and displays a second indicator indicating the virtual speed on the display unit, and for switchings the automatic driving mode to the manual driving mode when the virtual driving speed is similar to the current speed of the vehicle.

First claim

What is claimed is:

1 . An apparatus for switching between driving modes of a vehicle with an automatic driving system, comprising:
an input unit for receiving an input to switch from an automatic driving mode to a manual driving mode; a speed sensor for determining a current speed of the vehicle; a display unit on which a first indicator indicating the current speed of the vehicle when the vehicle is in the automatic driving mode is displayed; a pedal sensor for determining a current displacement distance of an accelerator pedal; a controller for determining a virtual speed according to the current distance displacement of the accelerator pedal when an input is received that requests switching of the automatic driving mode of the vehicle to the manual driving mode if the vehicle is in the automatic driving mode and displays a second indicator indicating the virtual speed on the display unit, and for switchings the automatic driving mode to the manual driving mode when the virtual speed is similar to the current speed of the vehicle.

2 . The apparatus of claim 1 , wherein when the virtual speed is similar to the current speed, the controller determines whether the virtual speed is being maintained similar to the current speed for a pre-set reference time, and
wherein, when the virtual speed is being maintained similar to the current speed for the pre-set reference time, the controller switches the automatic driving mode to the manual driving mode.

3 . The apparatus of claim 1 , wherein when the virtual speed is similar to the current speed, the controller displays a pre-set time that counts down on the display unit before the automatic driving mode is switched to the manual driving mode, and wherein when the displayed pre-set time is counted down and the pre-set time elapses, the controller switches the automatic driving mode to the manual driving mode.

4 . The apparatus of claim 1 , further comprising:
a steering sensor for determining a current steering angle of a steering mechanism for the vehicle, wherein when the vehicle is in the automatic driving mode, a third indicator indicating the current steering angle of the steering mechanism for the vehicle on the display unit.

5 . The apparatus of claim 4 , further comprising:
a wheels sensor for determining an angle of revolution for a steering wheel of the vehicle; wherein the controller detects a virtual steering angle corresponding to the angle of revolution of the steering wheel of the vehicle when the input is received, and displays a fourth indicator indicating the detected virtual steering angle on the display unit.

6 . The apparatus of claim 5 , wherein the controller determines whether the virtual steering angle is similar to the current steering angle, and
wherein, when the virtual steering angle is similar to the current steering angle, the controller switches the automatic driving mode to the manual driving mode.

7 . The apparatus of claim 6 , wherein when the virtual steering angle is similar to the current steering angle, the controller determines whether the virtual steering angle is being maintained similar to the current steering angle for a pre-set reference time, and
wherein when the virtual steering angle is being maintained similar to the current steering angle for the pre-set reference time, the controller switches the automatic driving mode to the manual driving mode.

8 . The apparatus of claim 7 , wherein, when it is determined that the virtual steering angle is similar to the current steering angle, the controller displays a pre-set time that will elapse before the automatic driving mode is switched to the manual driving mode on the display unit, and
wherein when the displayed pre-set time is counted down and the pre-set time elapses, the controller switches the automatic driving mode to the manual driving mode.

9 . The apparatus of claim 1 , wherein when the input is received, the controller determines whether an object recognized by an advanced driving assist system (ADAS) is in a direction of a driver's gaze, which is recognized by a driver state monitoring (DSM) system and
wherein when the object is in the direction of the user's gaze, the controller switches the automatic driving mode to the manual driving mode.

10 . The apparatus of claim 9 , further comprising:
a wheels sensor for determining an angle of revolution for a steering wheel of the vehicle, wherein the controller detects a virtual steering angle corresponding to the angle of revolution of the steering wheel of the vehicle when the input is received, and determines whether the virtual steering angle is similar to a current steering angle of the vehicle, and wherein the virtual steering angle is similar to the current steering angle, the virtual speed is similar to the current speed, and the object is in the direction of the driver's gaze, the controller switches the automatic driving mode to the manual driving mode.

11 . A method of switching between driving modes of a vehicle, for use in a vehicle that is capable of automatic driving and manual driving, the method comprising:
displaying a first indicator indicating a current speed of the vehicle on a display unit when the vehicle is in an automatic driving mode; determining a current displacement distance of an accelerator pedal; detecting a virtual speed according to the current displacement distance of the accelerator pedal of the vehicle moves when an input that requests switching of the automatic driving mode of the vehicle to a manual driving mode is received through an input unit, if the vehicle is in the automatic driving mode; displaying a second indicator indicating the detected virtual speed on the display unit; and switching the automatic driving mode to the manual driving mode when the virtual driving speed is similar to the current speed.

12 . The method of claim 11 , wherein the switching the automatic driving mode to the manual driving mode includes:
determining whether the virtual speed is being maintained similar to the current speed for a pre-set reference time when the virtual speed is similar to the current speed, and switching the automatic driving mode to the manual driving mode when the virtual speed is being maintained similar to the current speed for the pre-set reference time.

13 . The method of claim 11 , wherein the switching of the automatic driving mode to the manual driving mode includes
displaying a pre-set time that elapses before the automatic driving mode is switched to the manual driving mode on the display unit when the virtual speed is similar to the current speed, and switching the automatic driving mode to the manual driving mode when the displayed pre-set time is counted down and the pre-set time elapses.

14 . The method of claim 11 , further comprising:
displaying a third indicator indicating a current steering angle of the vehicle on the display unit when the vehicle is in the automatic driving mode.

15 . The method of claim 14 , further comprising:
detecting a virtual steering angle corresponding to an angle of revolution of the steering wheel of the vehicle when the input is received; and displaying a fourth indicator indicating the detected virtual steering angle on the display unit.

16 . The method of claim 15 , wherein the switching of the automatic driving mode to the manual driving mode includes
determining whether the virtual steering angle is similar to the current steering angle, and switching the automatic driving mode to the manual driving mode when the virtual steering angle
