ULTRASONIC DISTANCE MEASUREMENT APPARATUS AND METHOD HAVING AUXILIARY FUNCTION FOR PARKING AND LANE CHANGE

摘要

The present invention is an ultrasonic distance measuring device, by mounting the ultrasonic sensor unit on the side and rear of the car to increase the distance measurement accuracy between the bumper and the object at the time of reversing and to alarm below a certain distance, the sensor unit mounted at both ends of the bumper when changing lanes The present invention relates to an ultrasonic distance measuring device and method having a parking assist and a lane change assist function for assisting in a lane change by alerting when an object in a blind spot of a rear view mirror is detected. In the device, when detecting an object between two sensor units, an error occurs between the actual distance to the bumper and the measurement distance, and there is a problem that there is no function of warning of a collision when changing lanes. Separated measurement mode to measure the distance by transmitting ultrasonic waves from the camera and receiving ultrasonic waves from the other sensor Helps the driver to change lanes to the city by generating an alert to detect objects in the rear-view mirror blind spot when nopyeotgo distance from the accuracy of any part of the bumper lane change by adding new algorithms.
