Description
Technical Field
The invention belongs to the technical field of parking assistance, and particularly relates to a parking posture correction system and method.
Background
With the improvement of living standard, more and more people are developing domestic automobiles and enjoying driving. In particular, in recent years, a large number of young adults acquire domestic driving qualification through examination after driving training. In the driving training process, a coach often teaches a method for judging the direction of the automobile through the point location to a learner, and the learner finishes the projects of reversing, warehousing, hill start and the like through the point location. The method for judging the automobile azimuth through the point positions can enable a novice driver to quickly master driving skills such as reversing and starting, but a plurality of parking lots in society are different from examination rooms and practice ranges, and are not provided with a plurality of universal fixed point positions, the parking positions of each parking lot are arranged differently, and for drivers with poor technical level, the posture of an automobile body relative to the parking positions after reversing and warehousing is often not correct, and parking operations are often needed to be carried out for a plurality of times, so that the method is very troublesome. Some drivers only park the car into the parking space, but the distance between the car and the side line of the parking space is small, the car leaves without adjustment, and when other drivers park the car aside, the distance between the two cars is small, so that the car is difficult to open or the car door cannot be opened to get off, and disputes among people can be easily generated under the condition.
Under the existing conditions, a plurality of automobiles are provided with reversing radar and reversing images, so that a driver can be assisted to park, but some owners park by watching the reversing images, or the distances between the automobiles and the side lines on two sides of a parking space are difficult to judge. If the patent with the publication number of CN104047455A provides a scheme, an infrared sensing device is arranged around a parking space, and when infrared rays are shielded in the reversing process of a vehicle, the device can give an alarm through a loudspeaker or display light to prompt a driver. But only display reminding by means of a loudspeaker or light, so that the judgment effect on the driver is limited; in the device, once other objects or pedestrians pass by accidentally, the device can also shield infrared rays and give an alarm or remind, and the recognition effect before parking assistance is not very accurate.
Accordingly, there is a need to provide a parking posture correction system and method to solve the above-mentioned problems.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a parking posture correcting system and method, which better help drivers to finish the assistance of parking, make the posture of parking more straight relative to the parking space, and make the probability of misjudgment when other objects or pedestrians pass through the parking space smaller.
The technical scheme of the invention is realized as follows:
compared with the prior art, the invention has the following beneficial effects:
the parking posture correcting system comprises a parking lot arranged indoors or underground, wherein a plurality of parking spaces are arranged on the ground in the parking lot, the right front of each parking space is a lane, and the right above each parking space is a ceiling; the ceiling is provided with a plurality of infrared induction frames and a plurality of loudspeakers, and each infrared induction frame and each loudspeaker correspond to one parking space;
the infrared induction frame comprises a plurality of reflection type infrared induction units which are uniformly distributed, and the infrared rays emitted by the reflection type infrared induction units are mapped into rectangular frames on the ground; the rectangular frame comprises 4 sides which are connected end to end in sequence, namely an a side, a b side, a c side and a d side, wherein the a side is attached to the inner edge of the front edge line of the parking space, and the b side, the d side and the c side are respectively 25-35 cm away from the inner edges of the left side line, the right side line and the rear side line of the parking space;

A parking posture correcting method, characterized in that a parking posture correcting system according to any one of claims 1 to 7 is applied to assist a driver in reversing and warehousing; the reflection type infrared sensing unit recognizes that the distance from the shielding object to the shielding object is an actual distance according to the emitted infrared rays, and a preset value L and a voice broadcasting intermittent value T are stored on the server; in a shielding state, the system controls the loudspeaker to carry out voice broadcasting sequentially every T seconds; when the actual distance R obtained by the identification of any one reflection type infrared sensing unit on one edge of the infrared sensing frame is smaller than a preset value L, the system judges that the corresponding edge is in a shielding state;
the method comprises the following steps:
s1, driving the automobile to reverse and put in a warehouse to an nth parking space by a driver, and if and only if the tail of the automobile passes through a n When on edge, the system recognizes as a n The side shielding is carried out, and the state of the current parking space is judged to be 'in the falling warehouse', wherein n is a natural number; step S2 is executed again;
s2, automobile body passing b n Edge or d n On edge, the system recognizes as b n Edge shielding or d n Edge shielding; when b n When the edge is blocked, the system controls the nth loudspeaker Y n Sending out a voice prompt 'please adjust to the right'; or when d n When the edge is blocked, the system controls Y n Sending out a voice prompt 'please adjust to the left'; b n Edge or d n When the edge is not blocked, then the system controls Y n Sending out a voice prompt of 'reversing, please notice';
s3, when b n Edge and d n If none of the edges is covered, if a n Side shielding and c n Edge-shielding, or a n Edge and c n None of the edges is covered, or a n Side is not covered and c n The system judges that the state of the current parking space is normal parking and controls a loudspeaker Y n And stopping broadcasting.
9. The method for correcting a parking posture according to claim 8, wherein said system is further provided with an abnormalityA median value W; in step S3, if the current parking space is "in the garage" and the duration exceeds W seconds, the system determines that the current parking space is "abnormal parking", and controls the speaker Y n Stopping broadcasting and informing a parking lot manager of checking the situation from the nth parking place.
10. A method of correcting a parking position as claimed in claim 8, wherein in step S1, if and only if a n When more than 80% of reflective infrared sensing units on the edge are recognized as being blocked, the system judges that a is n Edge shielding.
