Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.
Referring to fig. 1, the present embodiment provides a battery charging and replacing facility and a battery charging port guiding battery charging and replacing method, including:
in step S1, the VCU (Vehicle Control Unit) detects a Vehicle warehousing operation. On the other hand, the detection can also be initiated from the charging and replacing facility side, such as by means of a vision system. It should be understood that the normal warehousing is R-gear (parking gear) warehousing, but the warehousing action applicable to the scheme may also be forward D-gear warehousing, so that the information transmitted to the VCU side is not only vehicle gear information, but also can be information captured by combining a camera image, for example, whether a parking space line exists is observed; or combining information of the garage system, such as entering a garage of a certain Internet of vehicles system or corresponding intelligent hardware equipment at the position of the garage. The vehicle entering action may be an automatic driving entering action, or an in-vehicle system guiding a driver to enter the vehicle manually.
And step S2, establishing communication connection between the electric automobile and the battery charging and replacing facility. Taking the most common charging pile as an example, the communication connection is mainly used for data interaction between the electric vehicle and the charging pile, such as transmitting charging pile type information, charging pile position information, charging pile availability information, charging pile performance parameter information and the like to a vehicle end, or transmitting related information (such as distance, authentication handshake information and the like) of the electric vehicle to the pile end. The communication connection can be initiated by an electric automobile end or a charging pile end; communication connections include, but are not limited to: wifi, Bluetooth BT, Zigbee, NFC, RFID and the like, and the Wifi mode is preferably used in the scheme, so that subsequent starting authentication is facilitated.
Step S3, the distance measuring transmitter is activated. The distance measuring transmitter can be arranged on the electric automobile and can also be arranged on the charging pile; when the distance measuring device is arranged on the electric automobile, the distance measuring device is preferably arranged at the position of a charging port, and at the moment, the corresponding distance measuring receiver is arranged on the charging pile; when the distance measurement transmitter is disposed at the charging and battery replacing facility, it is preferably disposed at the charging gun/battery replacing part, and in this case, the distance measurement receiver is disposed at the charging port/battery to be replaced of the electric vehicle.
Step S4, adjusting the parking posture and the final parking position of the vehicle based on the distance information obtained by the distance measuring receiver. Specifically, according to the distance obtained by the distance measuring device and the adaptation type of the charging port and the charging and replacing facility, the warehousing posture of any angle such as forward warehousing, reverse warehousing or oblique warehousing is carried out, but the vehicle is required to be finally parked at a reasonably and appropriately-met warehousing position, and the operation can be judged through cameras around the vehicle. Preferably, distance measuring device can be ultrasonic ranging device, also can be laser, infrared, radar, GPS etc. different range finding modes, and its range finding process has the difference a little, and this is prior art content, does not give unnecessary details at this scheme, the preferred ultrasonic ranging of this scheme or radar range finding mode.
Preferably, the length of the charging cable is added to the calculation factor of the distance measurement, that is, the distance between the charging port and the charging facility at the final warehousing position can ensure that the pull-out length of the cable is shortest.
Further, before/while/after the communication connection is established in step S2, it is determined that the electric vehicle is a legal vehicle corresponding to the battery charging and swapping facility, and if the result is yes, the battery charging and swapping authentication procedure is started and the authentication is passed.
Further, in order to reduce the energy consumption of the distance measuring device, the distance measuring device may be started after the vehicle entering the garage is detected and the vehicle establishes a communication connection with the battery charging and replacing facility.
Further, the authentication determination process may specifically be a comparison of built-in secret key data, such as a vehicle frame number (VIN code) of the electric vehicle, an engine number (motor number), a battery number, a special identification code preset and stored in the electric vehicle, or other numbers capable of identifying the identity of the electric vehicle, and the determination subject may be a stub or a cloud.
Furthermore, in order to enhance the safety, a secondary authentication mechanism can be added, because there is a process in backing up, and the vehicle is completely stopped when the authentication is passed, and the user pulls out the gun to charge, the secondary authentication can be confirmed by a power line carrier mode after the charging gun is inserted into the EV charging port, possibly because the authentication protection time (for example, the charging is not automatically restored to the initial state within 3 minutes), and the charging is started when the charging gun is passed.
Further, after the vehicle is put into the garage in step S4, the charging and battery replacing operation is performed on the electric vehicle that passes the authentication (is verified to be a legal vehicle), and at this time, the peg is authorized to charge the EV.
According to the method, through interaction of the charging and replacing facility and the electric automobile, when the charging and replacing are needed in a parking garage, the closest distance between the charging pile and a target charging port is calculated in real time, so that the vehicle is guided to park in a parking space or a position in the parking space with the closest distance, and meanwhile, the length of the charging wire in the charging and replacing facility is merged into the calculation process, so that the problems that the charging distance between different vehicle types and the charging and replacing facility such as a fixed charging pile is inaccurate to estimate, the charging wire is too long, or various user experiences on a trailer are poor are solved. The problem of fill electric pile and the unmatched position of car charging mouth at present is improved, a user experience is good self-adaptation and the solution of charging is guided. Meanwhile, the problem that different charging ports are matched with different types of charging and battery replacing facilities is solved. The adaptation process can be intelligently decided without user confirmation. In addition, the authentication mechanism is synchronously embedded in the communication process, so that compared with the traditional charging pile authentication method which needs card swiping, fingerprint swiping, iris and the like or uses a mobile phone APP, or the traditional physical lock and physical key mode is better, the intelligent charging pile authentication method is more intelligent, and the user experience is better.

At the moment, when the vehicle VCU detects that the vehicle has a parking action or a parking request, communication connection is started, the vehicle and the AC pile/DC pile are respectively subjected to handshake, the availability of the piles is identified, the vehicle-mounted system can recommend the vehicle owner to select AC slow charging or DC fast charging according to the historical charging habit or time priority/battery life priority mode of the vehicle owner, the system can also automatically select, and after the selection is finished, communication connection is established, and authentication handshake is started. And after the step or at the same time, distance information judgment is carried out, assuming that the AC charging is selected to be used in the embodiment, because the AC charging port is close to the head position on the left side of the vehicle body, the system feeds back according to the distance information and adds the cable length information of the AC charging pile, and the warehousing posture and the reasonably-compliant warehousing position are automatically calculated: in this embodiment, the forward-drive G1 position or the reverse-drive G2 position may be selected, and since the charging port is located near the vehicle head side, the forward-drive G1 position is the optimal selection (the selection closest to the vehicle head).
Certainly, the present disclosure is only described by taking an example, in reality, various scenes are not enumerated, and other special scenes such as the occupied parking space or the occupied parking space are occupied, at this time, intelligent determination needs to be performed by combining a vehicle body camera, and the warehousing mode is not limited to backing or driving in the forward direction, or driving in the lateral direction (at this time, the garage needs to be large enough).
In addition, it is worth to be noted that the specific method for measuring and calculating the distance between the charging pile and the charging port of the automobile is not described in detail in the present invention, and the present invention is a prior art and focuses on a system determination process by combining information such as distance, legal garage position, charging pile and charging port type.
After the vehicle is put in storage, authentication is completed through previous communication handshake between the vehicle and the pile, at the moment, the gun is pulled out and inserted into the corresponding charging port to start charging, card swiping or re-verification is not needed, and the whole process is completed.
