Title:
ULTRASONIC SENSOR MODULE FOR IMPROVING PRECISION OF DISTANCE MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2019/066210
Kind Code:
A1
Abstract:
An ultrasonic sensor module for detecting and reporting a nearby object during the travel or parking of a vehicle according to the present invention comprises: two or more ultrasonic sensors which are mounted on the vehicle and are for transmitting ultrasonic signals and receiving ultrasonic signals that are reflected back from the object; a driving unit for driving the ultrasonic sensors; a control unit which controls the overall operation of the ultrasonic sensor module and uses the ultrasonic signals received by the two ultrasonic sensors to calculate the vertical distance between the object and the vehicle by means of a triangulation method. According to the present invention, there is an effect in that the distance to the object can be more accurately calculated using the triangulation method to improve the accuracy of a distance measurement.
