a method for driving ultrasonic sensors includes : transmitting a lin communication message from an upper controller to ultrasonic sensors on a lin network ; receiving , by the ultrasonic sensors , the lin communication message ; confirming , by the ultrasonic sensors , a command of a protected identifier field of the lin communication message ; and if the command of the pid field is an object sensing command , measuring a distance from an object by allowing the ultrasonic sensors to directly emit an ultrasonic wave independent of values of the remaining fields of the lin communication message .
