The invention discloses an anti-collision braking system for automobile parking. The system comprises a front waterproof ultrasonic probe, a rear waterproof ultrasonic probe, a left waterproof ultrasonic probe and a right waterproof ultrasonic probe which are installed on an automobile. The front waterproof ultrasonic probe, the rear waterproof ultrasonic probe, the left waterproof ultrasonic probe and the right waterproof ultrasonic probe are connected with a central controller through signal lines. A single chip microcomputer circuit board is connected with a voice loudspeaker through a relay terminal. A front waterproof ultrasonic control unit connected with the front waterproof ultrasonic probe, a rear waterproof ultrasonic control unit connected with the rear waterproof ultrasonic probe, a left waterproof ultrasonic control unit connected with the left waterproof ultrasonic probe and a right waterproof ultrasonic control unit connected with the right waterproof ultrasonic probe are arranged in the central controller. According to the anti-collision braking system for automobile parking, barriers on the periphery of an automobile body are detected in the parking process, and the voice loudspeaker gives an alarm when the distance between the automobile body and the barriers is smaller than the distance required by a driver so as to guide the driver to complete parking.
Description
technical field [0001] The invention belongs to the technical field of automotive electronics applications, and in particular relates to the application of ultrasonic ranging technology in the process of parking a car. Background technique [0002] Ultrasonic distance measurement technology is a method of calculating the distance from the ultrasonic emission point to the obstacle point by recording the interval time between the emission and reception of the ultrasonic wave by taking the propagation speed of the ultrasonic wave in the air as a variable. The AT89S52 microcontroller is a widely used intelligent microcontroller with 3 timers / counters. The job is stable and the price is low. The traditional reversing radar can only monitor the obstacles at the rear of the car during parking, and cannot monitor other directions. Patent No. 200810008330.X discloses a reversing radar. The position where the ultrasonic probe is installed in the patent is only the front and rear pos...
