Problems solved by technology

[0008] In addition, when the original vehicle-mounted ultrasonic sensor is driving at high speed, the ultrasonic wave emitted by the sensor has a speed that cannot be ignored compared with the sound wave, so it will produce the Doppler effect, which has the problem of low reliability of the ultrasonic sensor

Abstract

The invention provides a method for processing ultrasonic wave sensor information of high speed drive in a vehicle through performing variable processing on action vehicle of an on-vehicle ultrasonic sensor, thereby improving reliability of the ultrasonic wave sensor in high speed drive of the vehicle. Furthermore, the method for processing the ultrasonic wave sensor information of high speed drive in the vehicle is characterized by comprising the steps of: a step of transmitting ultrasonic wave by the on-vehicle ultrasonic sensor; a step of transmitting a next ultrasonic wave when the period of the ultrasonic wave between transmission and receiving exceeds a preset action period; and a step of measuring a distance to an obstacle through the reflected wave when the reflected wave of the ultrasonic wave which is reflected by the obstacle is received.

Description

technical field [0001] The present invention relates to an adaptive ultrasonic sensor information processing method when the vehicle is running at high speed, specifically refers to the high-speed response to the ultrasonic measurement signal when the vehicle is running at high speed, reducing the communication obstacle signal, thereby improving the perception performance of the vehicle when driving at high speed An adaptive ultrasonic sensor information processing method. Background technique [0002] In general, an ultrasonic sensor refers to a sensor that forms ultrasonic waves through the piezoelectric principle of piezoelectric elements, and transmits and receives the formed ultrasonic waves. The vehicle-mounted ultrasonic sensor is composed of a single sensor unit, which has the function of transmitting and receiving ultrasonic waves, and determines the distance between the corresponding vehicle and the obstacle based on the measured time information by measuring the t...
