Electronic control device and method
The disclosure relates to an electronic control device and method. 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.
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.
2. 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.
3. 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.
4. 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.
5. 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.
6. The electronic control device of claim 1 , wherein the controller adjusts the frequency based on the object information obtained by the sensor unit.
7. 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.
8. 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.
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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
