Abstract
Disclosed herein is an ultrasonic sensor control device that controls an ultrasonic sensor device configured to transmit and receive ultrasonic waves. The ultrasonic sensor control device includes a transmission control section configured to control transmission of a transmission ultrasonic wave at a first frequency through the ultrasonic sensor device, a reception section configured to receive a reception ultrasonic wave through the ultrasonic sensor device, and a device control section configured to control the ultrasonic sensor device to set given frequencies as a transmission frequency of the transmission ultrasonic wave and a reception frequency of the reception ultrasonic wave. The device control section changes the reception frequency in such a manner that the reception frequency is a frequency different from the first frequency during a first period including at least a transmission period during which the transmission ultrasonic wave is transmitted.
