Problems solved by technology

[0008] There is no warning for pedestrians or electric vehicles or motor vehicles when the door is opened, and there is no effective early warning for the inside. The current car door, the driver and passengers in the car, carelessly open the door, causing traffic accidents, which happen frequently
The design of the car door opening system is insufficient, resulting in frequent accidents when the door is opened, which is unsatisfactory

Abstract

The invention discloses a vehicle door opening auxiliary monitoring system and method based on ultrasonic radar. When a human body infrared sensor detects that a human body signal exists in a vehicleand a vehicle speed sensor detects that the vehicle speed is zero or a vehicle lock state recognizer detects that a vehicle lock is in an open state, a controller sends a starting instruction to an ultrasonic generator; the ultrasonic generator starts to send an ultrasonic signal after receiving the starting instruction, and the ultrasonic signal is subjected to amplitude amplification through a voltage amplifier; the current is amplified by a power amplifier, and is finally sent to the ultrasonic radar by a switch filter, and the ultrasonic radar sends out the signal; meanwhile, the ultrasonic radar receives a feedback signal, the feedback signal is amplified through a signal amplifier, the amplified signal is sent to a processor for signal processing, and the processing result is displayed to people in the vehicle through the display; the people in the vehicle are reminded to notice the dynamic states of pedestrians and vehicles around the current vehicle body through a voice prompter.

Description

technical field [0001] The present disclosure relates to an ultrasonic radar-based vehicle door opening auxiliary monitoring system and method. Background technique [0002] The statements in this section merely enhance the background related to the present disclosure and may not necessarily constitute prior art. [0003] Because traffic accidents caused by opening the door are common, car owners and passengers do not pay attention to the front and rear road conditions when opening the door, and may hit a moving motorcycle or other cars, causing traffic accidents. [0004] News example: Earlier, a traffic accident occurred at the intersection of Renmin Road and Gongyuan Road in Qidong City, Jiangsu Province. When a taxi driver opened the door, he neglected to observe and knocked down a passing battery car. After the woman cyclist fell to the ground, she was unfortunately sucked into the bottom of the car by a passing bus, her head was crushed and she died on the spot . ...
