| 摘要 |
<p>The present invention relates to a device and a method to optimize the driving frequency of an ultrasonic sensor. The driving frequency optimizing device of an ultrasonic sensor includes: a measurement unit which measures excitation time of the ultrasonic sensor of each frequency by variously applying a frequency within a preset specific frequency area to the ultrasonic sensor cell; an acquisition unit which acquires an optimum driving frequency of the ultrasonic sensor cell based on the excitation time of each frequency measured by the measurement unit; and a control unit which sets the optimum driving frequency acquired in the acquisition unit as the driving frequency of the ultrasonic sensor cell.</p> |
