The present invention provides a processor, a sensor device, a control system, and a processing method capable of suppressing an increase in the number of mounted sensors. [0002] A processor 132 is a processor 132 that processes a sensor signal output from a sensor mounted to a vehicle, and includes: an acquisition section 132a that acquires the sensor signal output from the sensor; a first processing section 132b that generates first output signals through first filters F11, F12, F13, F14, F15, F16, each of which extracts a first frequency band from the sensor signal acquired by the acquisition section 132a; a second processing section 132c that generates second output signals through second filters F21, F22, F23, F24, F25, F26, each of which extracts a second frequency band, which differs from the first frequency band, from the sensor signal acquired by the acquisition section 132a; and an output section 132d that outputs the first output signal and the second output signal at once.
