Vehicle control system and control method thereof
An automotive control system includes a plurality of control units including a touch sensor. The automotive control system also includes a control unit recognizer that recognizes a control unit of the plurality of control units that a driver has touched through the touch sensor. The automotive control system also includes a voice recognizer that recognizes selection of a function of an automotive information appliance by analyzing a voice command from the driver. The automotive control system also includes a controller that connects the selected function with the recognized control unit and controls the selected function according to operation of the recognized control unit.
1. An automotive control system comprising:
a plurality of control units including a touch sensor;
a control unit recognizer that recognizes a control unit of the plurality of control units that a driver has touched through the touch sensor;
a voice recognizer that recognizes selection of a function of an automotive information appliance by analyzing a voice command from the driver; and
a controller that connects the selected function with the recognized control unit and controls the selected function according to operation of the recognized control unit, and
wherein when the voice command fails to be recognized, the controller creates a list of probable functions in accordance with a priority of similarity with the voice command, provides the list for display, and outputs a function having the next priority in the list as the selected function in accordance with the operation of the recognized control unit touched by the driver.
2. The automotive control system of claim 1 , wherein the touch sensor senses approach or touch by the driver's hand, using any one of an impedance sensor, an optical sensor, and a button-type sensor.
3. The automotive control system of claim 1 , wherein the control unit is at least any one of a knob unit that can be rotated, a joystick unit that can select directions, and a slider unit.
4. The automotive control system of claim 1 , wherein the voice recognizer recognizes selection of the function of the automotive information appliance by analyzing a voice command, which is inputted with the control unit touched, using a voice engine.
5. The automotive control system of claim 1 , wherein the selected function is a main function and the voice recognizer directly selects lower level menus for the main function without an intermediate process by analyzing the voice command.
6. The automotive control system of claim 1 , wherein for analyzing the voice command, the voice recognizer limits range of a database of voice recognition words to menus for the selected function.
7. The automotive control system of claim 1 , wherein the controller activates the voice recognizer when receiving, from the control unit recognizer, information about a control unit touched by the driver.
8. An automotive control system comprising:
a plurality of control units including a touch sensor;
a control unit recognizer that recognizes a control unit of the plurality of control units that a driver has touched through the touch sensor;
a voice recognizer that recognizes selection of a function of an automotive information appliance by analyzing a voice command from the driver; and
a controller that connects the selected function with the recognized control unit and controls the selected function according to operation of the recognized control unit,
wherein the controller creates a list of functions which have been recently selected by voice commands for a predetermined period of time, and outputs a function in the list as the selected function in accordance with the operation of the recognized control unit touched by the driver.
9. The automotive control system of claim 1 , wherein when the driver's touch is not recognized at the control unit for a predetermined period of time, or when the driver inputs a voice command for stopping the selected function, the controller displays an image related to a previous function and deletes a displayed image related to the stopped function.
10. An automotive control method for selectively designating and performing various functions of a vehicle, the method comprising:
recognizing a control unit of a plurality of control units in a vehicle, that is touched by a driver;
recognizing selection of a function of an automotive information appliance by analyzing a voice command from the driver;
connecting the selected function with the recognized control unit for cooperation and controlling the selected function according to operation of the recognized control unit;
returning to a function set as a default of the recognized control unit when the recognized control unit completes performing the selected function; and
when the voice command fails to be recognized, creating a list of probable functions in accordance with a priority of similarity with the voice command, providing the list for display, and outputting a function having the next priority in the list as the selected function in accordance with the operation of the recognized control unit touched by the driver.
11. The method of claim 10 , wherein in the recognizing the selection of the function, a voice recognition function is activated with the driver's touch of the control unit.
12. The method of claim 10 , wherein the selected function is a main function of the automotive information appliance, and in the connecting of the selected function with the recognized control unit, lower level menus for the main function are directly connected without an intermediate process.
13. The method of claim 10 , wherein in the returning to the function set as the default in the control unit, when the driver's touch is not recognized at the control unit or when the driver deactivates the function through a voice command, it is determined that the driver has stopped the function.
14. The method of claim 10 , wherein the connecting of the selected function with the control unit includes stopping the default function set of the control unit and giving authority for performing the selected function.
15. An automotive control method for selectively designating and performing various functions of a vehicle, the method comprising:
recognizing that a driver has touched an integrated control unit in a vehicle;
recognizing selection of a function of an automotive information appliance by analyzing a voice command from the driver;
connecting the selected function with the recognized control unit for cooperation and controlling the selected function according to operation of the recognized control unit;
storing a last function connected prior to the selected function, when the control unit completes performing the selected function;
calling and displaying the last function, and performing the last function, when the integrated control unit is touched again; and
when the voice command fails to be recognized, creating a list of probable functions in accordance with a priority of similarity with the voice command, providing the list for display, and outputting a function having the next priority in the list as the selected function in accordance with the operation of the recognized control unit touched by the driver.
