Problems solved by technology
[0002] In recent years, in some places where the parking management is chaotic, due to the visual blind spots around the car, the driver cannot judge whether there is anyone in the blind spot during the start of the car, and there are often records of drivers hurting people when starting the car. It has caused serious loss of life and property and bad social impact. Therefore, it is very necessary to perform blind spot detection and alarm during the starting process of the car.
[0003] The working method of the automobile anti-collision system in the prior art usually uses a CCD camera to operate. The CCD camera is a photodetector used to simulate the human eye. Due to its high cost and sensitivity to the external environment, it is widely used in many This technique should not be used in any occasion

The invention belongs to the technical field of automobile collision avoidance and particularly relates to an operating method of an automobile starting collision avoidance system. The operating method includes: initializing the automobile starting collision avoidance system, judging whether a speed sensor acquires automobile speed or not, restarting the speed sensor if the automobile speed is notacquired, judging whether display of a touch display screen circuit is normal or not, restarting the touch display screen circuit if display is abnormal, judging detection results of an ultrasonic radar sensor circuit or a millimeter wave radar sensor circuit are normal or not, and if the detection results of one of the ultrasonic radar sensor circuit and the millimeter wave radar sensor circuitare abnormal, enabling an alarm display circuit to alarm, and performing emergency brake through a step motor control circuit. When an obstacle close to an automobile body is detected, timely brakingcan be realized, so that accidents are prevented. In addition, high sensitivity, high stability, high interference resistance and low cost are realized.
