Background
Ultrasonic waves are special sound waves with basic physical characteristics of refraction, reflection, interference, etc. of sound waves. The ultrasonic ranging sensor emits ultrasonic waves outwards through the ultrasonic wave emitting device, and the distance length is measured by the time difference from when the ultrasonic waves are received through the receiver.
The ultrasonic transmitter transmits an ultrasonic signal to one direction outside, the ultrasonic wave is started to be timed at the same time of transmitting the ultrasonic wave, the ultrasonic wave is transmitted through the air, the ultrasonic wave can be immediately reflected and transmitted back when encountering an obstacle during the transmission, and the ultrasonic receiver immediately stops timing at the moment of receiving the reflected wave.
The ultrasonic reversing radar sensor for the automobile can inform the driver of surrounding obstacles, so that the trouble caused by front, back, left and right explorations of the driver during parking, reversing and starting the automobile is eliminated, the driver is helped to sweep out the defects of dead angles of vision and blurred vision, and the driving safety is improved.
The application of the ultrasonic car reversing radar sensor on the car can be combined with the ECU to form a system for use, and generally, there are several ultrasonic car reversing radar sensors (4, 8, or 12 are combined into a group). Each sensor can detect the distance according to the transmission ultrasonic wave of certain law ultrasonic wave, because the environment in the car driving is very complicated, and the ultrasonic wave that launches out can not all be the perpendicular reflection back after meetting the barrier, and probably the reflected wave can be received by adjacent sensor, forms the interference of meeting, has influenced the accurate determination of sensor detection distance.
The ultrasonic reversing radar sensors on the automobile have intervals of more than 30cm, and the sensors are subjected to certain treatment by software, so that the possibility of mutual interference between the sensors is greatly reduced.
