Abstract

The invention provides an automobile ultrasonic collision avoidance system, and belongs to the field of an automobile device. The ultrasonic collision avoidance system comprises a coding display module, an alarm module, a controller module, an ultrasonic emission module, an ultrasonic reception module and an automatic braking module. The output ends of the coding display module, the alarm module and the automatic braking module are connected with the controller module; the output end of the automatic braking module is connected with an automobile rotation shaft; the input end of the ultrasonic emission module is connected with the controller module; the output signal of the ultrasonic emission module is emitted to the ultrasonic reception module through a barrier; and the output end of the ultrasonic reception module is connected with the controller module.

Description

technical field [0001] The invention relates to the field of automobile equipment, in particular to an automobile ultrasonic collision avoidance system. Background technique [0002] With the development of the economy, the transportation industry is becoming more and more prosperous. However, due to the difficulty in keeping up with hardware such as road conditions and traffic management, coupled with subjective principles such as driving overtaking, leaving the car to drive away, and misestimating the distance between cars, traffic accidents collide frequently. occur. The fundamental measure to solve this problem is to install a device that can automatically track and measure distances and automatically brakes in dangerous distances for moving cars. [0003] Due to the development of electronic technology, laser ranging, microwave radar ranging, ultrasonic ranging and ultrasonic line ranging have appeared successively. Among them, the laser ranging is to detect the dista...
