Detailed ways

The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

As shown in FIG. 1 , the embodiment provides a charging and replacing facility and a charging port guiding charging and replacing method, including:

In step S1, the VCU (Vehicle Control Unit) detects the vehicle warehousing action. On the other hand, it is also possible to initiate detection from the charging and discharging facility, such as relying on a vision system. It should be understood that the normal warehousing is the R gear (parking gear) storage, but the warehousing action applicable to this scheme may also be the forward D gear warehousing, then it is not only the vehicle gear transmitted to the VCU side. The bit information can also be combined with camera image capture information, such as observing whether there is a parking line; or combined with garage system information, such as entering a corresponding intelligent hardware device in a garage or garage location of a car network system. Moreover, the vehicle storage operation may be automatic driving into the warehouse, or the in-vehicle system may guide the driver to perform manual storage.

In step S2, a communication connection between the electric vehicle and the charging and replacing facility is established. Taking the most common charging pile as an example, the communication connection is mainly used for data interaction between electric vehicles and charging piles, such as transmission charging pile type information, charging pile position information, charging pile availability information, charging pile performance parameter information, etc. Or transmit information about the electric vehicle (such as distance, authentication handshake information, etc.) to the pile end. The communication connection may be initiated by the electric vehicle end or by the charging pile end; the communication connection manner includes but is not limited to: Wifi, Bluetooth BT, Zigbee, NFC, RFID, etc. In this case, the Wifi mode is preferably used to facilitate subsequent startup. right.

In step S3, the distance measuring transmitter is activated. The distance measuring transmitter can be disposed on the electric vehicle or on the charging pile; when configured on the electric vehicle, it is preferably disposed in the charging port position, and at this time, the corresponding distance measuring receiver is disposed on the charging pile; When the distance measuring transmitter is disposed on the charging and discharging device, it is preferably disposed on the charging gun/replacement unit. At this time, the distance measuring receiver is disposed on the charging port/replaced battery of the electric vehicle.

Step S4, adjusting the warehousing posture of the vehicle and the final warehousing position according to the distance information obtained by the distance measuring receiver. Specifically, according to the distance obtained by the distance measuring device, and the type of adaptation of the charging port and the charging and replacing device, the storage posture at any angle such as forward storage, reverse storage or oblique storage is performed, but it is necessary to ensure at the same time. The vehicle is finally parked in a reasonably compliant storage location, which can be determined by the vehicle's entire camera. Preferably, the distance measuring device may be an ultrasonic distance measuring device, or may be a laser, an infrared, a radar, a GPS, etc., and different ranging methods, the ranging process is slightly different, which is a prior art content, and is not described in this embodiment. This solution is preferably an ultrasonic ranging or radar ranging method.

Preferably, in the calculation factor of the distance measurement, the length of the charging cable should also be added, that is, the final storage location is the distance between the charging port and the charging facility to ensure that the cable has the shortest pulling length.

Further, before step S2 establishes the communication connection before/simultaneously/after determining that the electric vehicle is a legal vehicle corresponding to the charging and replacing facility, if the conclusion is yes, the charging and replacing power authentication process 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 restarted after the vehicle warehousing action is detected and the vehicle establishes a communication connection with the charging and discharging facility.

Further, the specific authentication judgment process may be a built-in key data comparison, such as an electric car frame number (VIN code), an engine number (motor number), a battery number, a preset, and stored in an electric car. Dedicated identification code, or other number that can identify the identity of the electric car, etc., the judgment subject can be a pile, or a cloud.

Further, in order to enhance security, a secondary authentication mechanism may be added, because there is a process of reversing, in the process of the above authentication passing to the vehicle completely stopped, and the user pulling the gun to charge, may be due to the authentication protection time ( If no charging automatically returns to the initial state within 3 minutes, then after the charging gun is inserted into the EV charging port, the second authentication can be confirmed by the power line carrier method, and the charging is started.

Further, after the vehicle is put into storage in step S4, the electric vehicle that has passed the authentication (verified as a legitimate vehicle) is charged and replaced, and at this time, the pile is authorized to charge the EV.

The method interacts with the electric vehicle through the charging and replacing facilities, and when the parking and storage needs to be charged and replaced, the nearest distance between the charging pile and the target charging port is calculated in real time, thereby guiding the vehicle to park in the parking space of the closest distance or The position inside the parking space, and the charging line length in the charging and replacing facilities are incorporated into the calculation process, which solves the problem that the charging distance between different models and charging and replacing facilities such as fixed charging piles is not accurate, and the charging line is pulled too long or on the trailer. The problem of poor user experience. The problem that the current charging pile does not match the position of the charging port of the vehicle is improved, and an adaptive guided charging solution with good user experience is provided. At the same time, the problem of adapting different charging ports to different types of charging and replacing facilities is solved. The adaptation process can be intelligently determined without user confirmation. In addition, the present invention integrates the authentication mechanism in the communication process itself, and needs to be swiped, brushed, irised, etc., or use a mobile APP, or a better traditional physical lock and physical key, to be more intelligent than traditional charging pile authentication. The user experience is better.

As shown in Fig. 2 and Fig. 3, the direction of the front of the vehicle is upwards in Fig. 2, the left side of the car is close to the front of the car, the AC slow charging port, and the right side is close to the front of the car, which is a DC fast charging port; in addition, the car is equipped with a distance.

At this time, when the vehicle VCU detects that the vehicle has a parking action or a parking request, the communication connection is started, and the vehicle shakes hands with the AC pile/DC pile respectively to identify the availability of the pile, and the vehicle system can be based on the owner's historical charging habit or time priority/ Battery life priority mode It is recommended that the owner choose AC slow charge or DC fast charge, or the system can automatically select. When the selection is completed, establish a communication connection and start the authentication handshake. Immediately following this step or at the same time, the distance information is determined. It is assumed that the AC charging is selected in this example. Since the AC charging port is close to the front position on the left side of the vehicle body, the system feeds back according to the distance information and adds the length information of the AC charging pile cable. Automatically calculate the storage position and reasonable compliant storage location: In this embodiment, the front end of the vehicle can be selected to enter the G1 position, or reversely parked into the G2 position. Because the charging port is located close to the front side of the vehicle, it is forwarded into the G1 position. Is the best choice (from the most recent choice).

Of course, this case is just an example. In reality, there are many scenes that are not enumerated one by one. Other special scenes such as parking spaces are occupied, or a certain part of the parking space is occupied. At this time, it is necessary to combine the body camera for intelligent judgment. The library method is not limited to reversing or forward driving, but also lateral driving (the garage needs to be large enough).

In addition, it should be noted that the present invention does not specify the specific method for calculating the distance between the charging pile and the charging port of the vehicle. The prior art is focused on the distance, legal garage position, charging pile and charging port type. System determination process.

After the vehicle is completed, the previous communication handshake between the vehicle and the pile has been completed. At this time, the gun is inserted into the corresponding charging port to start charging, and no need to swipe or re-verify to complete the entire process.
