Problems solved by technology

[0004] The disadvantages of parallel parking mentioned above are: this parking method depends on the driver’s driving skills. Most car users need a parking space about 1.8 meters longer than the vehicle body to successfully complete parallel parking, which requires a relatively large amount of space. parking space
With poor driver skill, parking can lead to traffic jams, nerve-wracking, often blocking traffic in one lane for several minutes, which can seriously disrupt traffic
Finally, parallel parking will cause many bumps, such as the bumper being bent, which will bring economic losses to the user

[0025] The processing flow of a method for realizing automatic parking based on wireless signal recognition provided by this embodiment is as follows: figure 1 As shown, the following processing steps are included:

[0026] Step S110, setting up a wireless signal transmitter in the area where the parking space is located, setting up a communication device, a driving control device and a wireless signal recognizer on the vehicle, and setting up an automatic parking control device outside the vehicle.

[0027] Embedding one or more wireless signal transmitters at a specific position inside or outside the parking space, setting a vehicle inspection ground induction coil at a specific position in the parking space, connecting the wireless signal transmitter and the vehicle inspection ground induction coil by wire, The vehicle detection ground sense coil detects the state of the parking space in real time, and if the vehicle has been stopped in the parking space, the state informat...

Embodiment 2

[0046] This embodiment provides a processing flow of an RFID-based automatic parking method as follows: figure 2 As shown, the following processing steps are included:

[0047] Step S210: Embedding RFID electronic tags and ground sensing coils for vehicle inspection in the area where the parking spaces are located, installing RFID identifiers, communication equipment, and driving control equipment on the vehicle, and installing automatic parking control equipment outside the vehicle.

[0048] One or more RFID electronic tags are buried in a specific position inside or outside the parking space. The above-mentioned specific positions include the center point of the parking space area, the vertices on the boundary line, etc. The principle of setting the specific location of each RFID electronic tag is: According to each The coordinate position information of the RFID electronic tag is comprehensively calculated to determine the position information of the entire parking space, ...

Embodiment 3

[0075] The implementation device for automatic parking based on wireless signal recognition provided by this embodiment, its specific implementation structure is as follows: image 3 As shown, specifically, the following modules may be included: a wireless signal transmitter 31, a wireless signal identifier 32, a communication device 33, a driving control device 34 and an automatic parking control device 35;

Abstract

The embodiment of the invention provides an automatic parking implementation method and device based on wireless signal recognition. The method comprises the steps that a wireless signal recognizer on a vehicle reads and obtains a wireless signal transmitted by a wireless signal transmitter, and information of the coordinate position of the wireless signal transmitter carried in the wireless signal is transmitted to automatic parking control equipment which is arranged outside the vehicle; the automatic parking control equipment utilizes the information of the coordinate position of the wireless signal transmitter for calculating and obtaining information of the location of a parking stall, according to the information of the location of the parking stall and information of the current location of the vehicle, relative positions and distance between the vehicle and the parking stall are calculated out, according to the relative positions and the distance, an automatic parking control instruction for the vehicle is generated, the automatic parking control instruction is transmitted to driving control equipment in the vehicle, and the driving control equipment implements the automatic parking control instruction, so that the vehicle is controlled to be parked into the parking stall automatically. By means of the automatic parking implementation method and device based on the wireless signal recognition, the automatic parking of the vehicle can be achieved.

Description

technical field [0001] The invention relates to the technical field of automatic parking, in particular to a method and device for realizing automatic parking based on wireless signal identification. Background technique [0002] In densely populated urban areas where parking spaces are limited, maneuvering a car into tight spaces has become a required skill for many drivers. [0003] At present, in parking lots in densely populated urban areas, the commonly used parking method is parallel parking. The process of parallel parking mainly includes: driving the car to the front of the parking space and parking next to the car in front. Turn the wheel towards the curb and cut the car back into the parking space at about 45°. When the front wheels of the car are parallel to the rear wheels of the vehicle in front, the driver straightens the front wheels and continues to reverse. After ensuring a certain distance from the vehicle behind through the rear view, the driver turns t...
