Abstract: A ranging device includes transducers, a transmission circuit, a reception circuit, a transfer data generation circuit, and a transfer circuit. The transmission circuit causes the transducers to transmit transmission waves. The reception circuit outputs a received signal obtained by digitizing a reflected wave of the transmission wave with a sampling frequency equal to or more than a frequency of the transmission wave. The generation circuit separates, into a target period and a non-target period, time-series received signals. The target period is a period in which a wave height is equal to or more than a threshold. The non-target period is a period in which a wave height is less than the threshold. The generation circuit performs thinning-out processing on received signals in the non-target period and generates waveform information indicating a waveform received by the transducer. The transfer circuit outputs the waveform information.

Abstract: A storage device stores a voltage value-horizontal distance characteristic that represents a relation between a horizontal distance between a primary coil and a secondary coil, and a voltage value. A characteristic setting unit sets a voltage value-horizontal distance characteristic that matches a vehicle state, on the basis of a value for the vehicle state (vehicle speed v, vehicle height h, and inclination i) detected by sensors and the voltage value-horizontal distance characteristic stored in the storage device. A horizontal distance estimation unit estimates the horizontal distance on the basis of the voltage value-horizontal distance characteristic and the voltage value.
