Abstract
A method of optimizing a frequency band by a vehicle controller includes, upon wirelessly connecting a new device to the vehicle controller, first determining frequency characteristic of the new device, second determining whether a frequency band is capable of being allocated to the new device in an available frequency band by using the determined frequency characteristic, and when the frequency band is not capable of being allocated to the new device as the second determination result, readjusting a bandwidth occupied by one or more pre-connected devices to ensure a band to be allocated to the new device.
Claims15
A method of optimizing a frequency band by a vehicle controller, the method comprising:
- upon wirelessly connecting a new device to the vehicle controller, first determining a frequency characteristic of the new device;
- second determining whether a frequency band is capable of being allocated to the new device in an available frequency band by using the determined frequency characteristic;
- and
- when the frequency band is not capable of being allocated to the new device as the second determination result, readjusting a bandwidth occupied by one or more pre-connected devices to ensure a band to be allocated to the new device,
- wherein the readjusting of the bandwidth includes shifting a position of a bandwidth occupied by at least one device of the one or more pre-connected devices on a frequency axis, and
- wherein the shifting of the position of the bandwidth is performed by sequentially releasing connection with the at least one device and then performing reconnection.
A non-transitory computer readable recording medium having recorded thereon a program for executing a method of optimizing a frequency band by a vehicle controller, wherein the method comprises:
- upon wirelessly connecting a new device to the vehicle controller, first determining a frequency characteristic of the new device;
- second determining whether a frequency band is capable of being allocated to the new device in an available frequency band by using the determined frequency characteristic;
- and
- when the frequency band is not capable of being allocated to the new device as the second determination result, readjusting a bandwidth occupied by one or more pre-connected devices to ensure a band to be allocated to the new device,
- wherein the readjusting of the bandwidth includes shifting a position of a bandwidth occupied by at least one device of the one or more pre-connected devices on a frequency axis, and
- wherein the shifting of the position of the bandwidth is performed by sequentially releasing connection with the at least one device and then performing reconnection.
A frequency band management controller of a vehicle for optimizing a frequency band, comprising:
- a wireless communication unit configured to wirelessly exchange data with one or more device;
- and
- a controller configured to, upon connecting a new device through the wireless communication unit, determine frequency characteristic of the new device, determine whether a frequency band is capable of being allocated to the new device in an available frequency band by using the determined frequency characteristic, and when the frequency band is not capable of being allocated to the new device, readjust a bandwidth occupied by one or more pre-connected devices to ensure a band to be allocated to the new device,
- wherein the controller readjusts the bandwidth to shift a position of a bandwidth occupied by at least one device of the one or more pre-connected devices on a frequency axis, and
- wherein the controller shifts the position of the bandwidth by sequentially releasing connection with the at least one device and then performing reconnection.
