Patent attributes
The present invention suggests a power control apparatus and method of a vehicle which switch the switching frequency component generated in the power supply module to odd-number times of a Nyquist frequency which is the most ignorable in the frequency domain which is used for the FMCW radar, thereby preventing the erroneous detection due to the switching frequency in the FMCW. The present invention provides a power control apparatus of a vehicle radar, including: a first frequency signal generating unit which generates a first frequency signal with a predetermined amplitude; a second frequency signal obtaining unit which converts a frequency value of the first frequency signal to obtain a second frequency signal; and a power supply control unit which controls the power to operate a vehicle radar based on the second frequency signal.
