Method and system for controlling trunk of vehicle to be opened or closed using wearable device
A method and a system for controlling a trunk to be opened or closed using a wearable device. The trunk may be opened or closed using a non-contact arrangement by causing the wearable device to generate an electromyogram (EMG) signal of a user depending on whether or not the user carries heavy luggage, and causing the vehicle to receive the EMG signal wirelessly.
1. A method for controlling a trunk of a vehicle to be opened or closed, comprising:
generating an electromyogram signal for reactivity of the body of a user using an electromyogram sensor worn on the body and transmitting the electromyogram signal,
wherein a strength of the electromyogram signal from the electromyogram sensor worn on an arm of the user is measured to open or close the trunk of the vehicle; and
controlling the trunk of the vehicle to be opened or closed depending on the strength of the electromyogram signal received by the vehicle and distance of the user from the vehicle.
2. The method for controlling a trunk of a vehicle to be opened or closed according to claim 1 , wherein, in a state in which a wearable device including the electromyogram sensor and a communication module wirelessly transmitting the electromyogram signal is worn on the body of the user, the vehicle wirelessly receives the electromyogram signal from the communication module of the wearable device.
3. The method for controlling a trunk of a vehicle to be opened or closed according to claim 1 , wherein, in a state in which a wearable device including the electromyogram sensor and a communication module transmitting the electromyogram signal through human body communication is worn on the body of the user, the vehicle receives the electromyogram signal from the communication module of the wearable device through the human body communication.
4. The method for controlling a trunk of a vehicle to be opened or closed according to claim 1 , wherein the vehicle transmits the electromyogram signal to an electronic device in a wired or wireless scheme to control the electromyogram signal to be used as an input signal for health care treatment or an input signal for direction indication in the electronic device.
5. The method for controlling a trunk of a vehicle to be opened or closed according to claim 1 , wherein the controlling of the trunk of the vehicle to be opened or closed includes opening the trunk of the vehicle when the strength of the electromyogram signal is larger than a threshold value in a state in which the trunk of the vehicle is closed and maintaining the trunk of the vehicle in an opened state when strength of the electromyogram signal measured at a predetermined period is larger than the threshold value.
6. The method for controlling a trunk of a vehicle to be opened or closed according to claim 5 , wherein the trunk of the vehicle is closed when the user moves from a rear of the vehicle by a predetermined distance or more, in the case in which the strength of the electromyogram signal measured at the predetermined period is the at threshold value or less after the trunk of the vehicle is opened.
7. The method for controlling a trunk of a vehicle to be opened or closed according to claim 1 , wherein the controlling of the trunk of the vehicle to be opened or closed includes maintaining the trunk of the vehicle in an opened state when strength of the electromyogram signal measured at a predetermined period is larger than a threshold value in a state in which the trunk of the vehicle is opened.
8. The method for controlling a trunk of a vehicle to be opened or closed according to claim 7 , wherein the trunk of the vehicle is closed when the user moves from a rear of the vehicle by a predetermined distance or more, in the case in which the strength of the electromyogram signal measured at the predetermined period is the threshold value or less.
9. A system for controlling a trunk of a vehicle to be opened or closed, comprising:
a communicator configured to receive an electromyogram signal for reactivity of the body of a user generated in an electromyogram sensor worn on the body of the user;
a distance sensor configured to sense a distance of the user from the vehicle; and
a trunk controller configured to control the trunk of the vehicle to be opened or closed depending on strength of the electromyogram signal and the distance of the user from the vehicle,
wherein the trunk controller measures the strength of the electromyogram signal from the electromyogram sensor worn on an arm of the user to open or close the trunk of the vehicle.
10. The system for controlling a trunk of a vehicle to be opened or closed according to claim 9 , wherein the communicator is configured such that in a state in which a wearable device including the electromyogram sensor and a communication module wirelessly transmitting the electromyogram signal is worn on the body of the user, the communicator wirelessly receives the electromyogram signal from the communication module of the wearable device.
11. The system for controlling a trunk of a vehicle to be opened or closed according to claim 9 , wherein the communicator is configured such that, in a state in which a wearable device including the electromyogram sensor and a communication module transmitting the electromyogram signal through human body communication is worn on the body of the user, the communicator receives the electromyogram signal from the communication module of the wearable device through the human body communication.
12. The system for controlling a trunk of a vehicle to be opened or closed according to claim 9 , further comprising an interface configured to transmit the electromyogram signal to an electronic device in a wired or wireless scheme, wherein the interface controls the electromyogram signal to be used as an input signal for health care treatment or an input signal for direction indication in the electronic device.
13. The system for controlling a trunk of a vehicle to be opened or closed according to claim 9 , wherein the trunk controller is configured to open the trunk of the vehicle when the strength of the electromyogram signal is larger than a threshold value when the trunk of the vehicle is closed and maintain the trunk of the vehicle in an opened state when strength of the electromyogram signal measured at a predetermined period is larger than the threshold value.
14. The system for controlling a trunk of a vehicle to be opened or closed according to claim 13 , wherein the trunk controller is configured to close the trunk of the vehicle when the user moves from a rear of the vehicle by a predetermined distance or more, when the strength of the electromyogram signal measured at the predetermined period is the threshold value or less after the trunk of the vehicle is opened.
15. The system for controlling a trunk of a vehicle to be opened or closed according to claim 9 , wherein the trunk controller is configured to maintain the trunk of the vehicle in an opened state when strength of the electromyogram signal measured at a predetermined period is larger than a threshold value in a state in which the trunk of the vehicle is opened.
16. The system for controlling a trunk of a vehicle to be opened or closed according to claim 15 , wherein the trunk controller is configured to close the trunk of the vehicle when the user moves from a rear of the vehicle by a predetermined distance or more, when the strength of the electromyogram signal measured at the predetermined period is at the threshold value or less.
