Mobile object is detected；
Step 2, when the translational acceleration of mobile object reaches design value, infrared induction sensor generate infrared ray quilt
It blocks, and reflexes in infrared induction sensor, infrared induction sensor is transferred to warning device for signal is generated at this time, alarms
Device analyzes signal in infrared induction sensor, and analysis result is transferred to car running computer cpu and is parsed, and parses
The result shows that control warning device is alarmed, prompt passengers can not be opened at this time if when opening car door can be dangerous at this time
Car door is opened, if the result shows that will not alarm when opening car door danger is smaller；
If car door can be opened in step 3, above-mentioned steps, passenger has rear of vehicle to fall when carrying out car door opening movement
Vehicle radar carries out distance perception to the subsequent mobile object of vehicle body and answers, and the distance of induction will be broadcast by the audio devices of vehicle interior
It puts, comes prompt passengers mobile object and vehicle body distance, so that passenger be made to select car door opening opportunity.
Further, the infrared induction sensor is infrared emission tube.
Further, the analysis result includes the acceleration of mobile object, mobile object moving direction to car door opening
The influence of maximum magnitude, mobile object are moved to the time close to vehicle.
Further, the distance to a declared goal is divided into safe distance, non-security distance, and safe distance is set as at least two vehicle bodies
Length distance, non-security distance are set as the distance within a length of wagon.
Further, the infrared inductor further includes signal amplifier, voltage comparator, delay circuit, the letter
Number amplifier is transferred to warning device for amplifying to the inductive signal of infrared induction sensor, and the voltage compares
Device is used to for vehicle power supply being adapted to power supply used in infrared inductor, and the delay circuit is used in vehicle power supply to infrared sense
It when device being answered to be powered, is delayed to electric current, avoids generating impact.
Further, the warning device is alarmed by interior car running computer display screen, sound equipment.
Beneficial effects of the present invention: the acceleration by judging vehicle body rear mobile object, to the safety of car door opening
It is detected, improves the precision of detection, while analyzing the movement of mobile object, to judge the safe journey of opening car door
Degree has hommization, in addition infrared inductor so that passenger be enable to carry out car door opening opportunity selection according to the actual situation
Structure is simple, allows for universal use, and distance to a declared goal is set as safe distance, non-security distance, and to safe distance,
Non-security distance is configured, and more improves the humanization level of detection and the precision of detection.
Specific embodiment
