Vehicle collision avoidance system

Abstract

The invention provides a vehicle collision avoidance system. The system comprises a single-chip microcomputer controller, an ultrasonic transceiver, a sound control alarm mechanism, a display mechanism, a brake apparatus and a temperature sensor. The ultrasonic transceiver is used for transmitting ultrasonic and feeding back the returned signal to the single-chip microcomputer controller; the temperature sensor is used for detecting the current temperature value; the single-chip microcomputer controller is used for calculating the distance between a vehicle and an obstacle, and when the distance is smaller than or equal to a preset distance threshold value, sending an alarm instruction to the sound control alarm mechanism and sending a brake instruction to the brake apparatus of the vehicle; the sound control alarm mechanism is used for receiving the alarm instruction sent by the single-chip microcomputer controller and sending an alarm signal; and the display mechanism is used for displaying the distance sent by the single-chip microcomputer controller, current temperature in and outside the vehicle, and current speed of the vehicle. According to the technical scheme, the system can prevent the vehicle from colliding into the barrier ahead.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a vehicle anti-collision system. Background technique [0002] With the continuous increase of vehicle ownership, traffic safety has become an increasingly serious problem. Currently, most vehicles are equipped with sensors for monitoring the distance between the vehicle and obstacles. When these sensors detect that the distance is too small, an alarm will sound to remind the owner to avoid colliding with the obstacle. [0003] However, the current anti-collision system usually can only be triggered when the vehicle is reversing, and when the vehicle is running normally, it cannot remind the obstacles in front of the vehicle. However, sometimes the car owner collides with objects in front of or around the vehicle due to fatigue driving or negligent observation. Therefore, there is an urgent need for a more comprehensive anti-collision system. Contents of the inventi...
