A DRIVING METHOD OF THE ULTRA SONIC SENSOR AND THE APPARATUS THEREOF

摘要

The present invention relates to a method for driving ultrasonic sensors. The method includes the steps of: transmitting an LIN communication message to ultrasonic sensors on a LIN network from a superordinate controller; receiving the LIN communication message by the ultrasonic sensors; identifying a command of a protected identifier (PID) field of the LIN communication message by the ultrasonic sensors; and immediately discharging ultrasonic waves by the ultrasonic sensors to measure a distance from an object regardless of values of the rest of fields of the LIN communication message if the command of the PID field is an object detection command, thereby minimizing a response time and a measurement error of a long-distance parking assistance system by improving LIN communication scheduling.
