According to the disclosure, an electronic control device comprises a sensor unit receiving a reception signal detecting an object and processing the reception signal to obtain object information, a power supply unit supplying power to the sensor unit and processing a signal for a predetermined frequency, and a controller adjusting a frequency processed by the power supply unit in each operation period of the sensor unit. ## Claims ### Claim 1 An electronic control device, comprising: a sensor unit receiving a reception signal detecting an object and processing the reception signal to obtain object information; a power supply unit supplying power to the sensor unit and processing a signal for a predetermined frequency; and a controller adjusting a frequency processed by the power supply unit in each operation period of the sensor unit, wherein the controller adjusts the frequency processed by the power supply unit as a value resultant from adding a predetermined frequency in each operation period of the sensor unit to a signal-processed frequency. ### Claim 2 (depends on 1) The electronic control device of claim 1, wherein the sensor unit includes: a radar signal module controlling to transmit a radar signal to an object using a transmission antenna; and a reception module receiving a reception signal reflected by the object, through a reception antenna. ### Claim 3 (depends on 2) The electronic control device of claim 2, wherein the sensor unit performs a signal reception operation for receiving the reception signal detecting the object through the transmission antenna and the reception antenna and a signal processing operation for obtaining the object information by processing the reception signal and sets the signal processing operation as a unit operation. ### Claim 4 (depends on 3) The electronic control device of claim 3, wherein the controller adjusts the frequency processed by the power supply unit after the unit operation is performed. ### Claim 5 (depends on 3) The electronic control device of claim 3, wherein the controller adjusts the frequency processed by the power supply unit while the reception signal processing operation is performed. ### Claim 6 (depends on 1) The electronic control device of claim 1, wherein the controller adjusts the frequency based on the object information obtained by the sensor unit. ### Claim 7 (depends on 6) The electronic control device of claim 6, wherein the controller excludes a frequency at which the object is detected from among to-be-adjusted frequencies. ### Claim 8 (depends on 1) The electronic control device of claim 1, wherein the power supply unit processes a signal through spread spectrum on the predetermined frequency, and wherein the controller adjusts the frequency to shift a center frequency of the frequency or to change a spread range of the frequency. ### Claim 9 An electronic control method, comprising: a frequency processing step supplying power to a sensor unit and processing a signal for a predetermined frequency; an object information reception step controlling to transmit a radar signal to an object, receiving a reception signal reflected by the object through a reception antenna, and processing the reception signal to obtain object information; and a frequency adjustment step adjusting the signal-processed frequency in each operation period of the sensor unit, wherein the frequency adjustment step includes adjusting the signal-processed frequency as a value resultant from adding a predetermined frequency in each operation period to a pre-processed frequency. ### Claim 10 (depends on 9) The electronic control method of claim 9, wherein the object information reception step includes a signal reception step receiving a reception signal detecting the object and a signal processing step obtaining the object information by processing the reception signal. ### Claim 11 (depends on 10) The electronic control method of claim 10, wherein the frequency adjustment step includes adjusting the signal-processed frequency after the signal processing step is performed. ### Claim 12 (depends on 10) The electronic control method of claim 10, wherein the frequency adjustment step includes adjusting the signal-processed frequency while the signal processing step is performed. ### Claim 13 (depends on 9) The electronic control method of claim 9, wherein the frequency adjustment step includes adjusting the frequency based on the object information obtained by the sensor unit. ### Claim 14 (depends on 13) The electronic control method of claim 13, wherein the frequency adjustment step includes excluding a frequency at which the object is detected from among to-be-adjusted frequencies. ### Claim 15 (depends on 9) The electronic control method of claim 9, wherein the frequency processing step includes processing a signal through spread spectrum on the predetermined frequency, and wherein the frequency adjustment step includes adjusting the frequency to shift a center frequency of the frequency or to change a spread range of the frequency.
