Detailed Description
The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the invention may be practiced.
Referring to fig. 1, an embodiment of the present invention provides an intelligent vehicle-mounted charging device, including:
an in-vehicle wireless control unit 1 and an in-vehicle charging control unit 2 connected to a vehicle body network;
the vehicle-mounted wireless control unit 1 is used for establishing wireless communication connection with the vehicle virtual key 3, performing identity authentication on the vehicle virtual key, and outputting an authentication result to the vehicle body network 4;
the vehicle-mounted charging control unit 2 is configured to charge the device to be charged 6 according to the corresponding charging mode according to the authentication result obtained from the vehicle body network 4, and the vehicle-mounted charging control unit 2 includes a vehicle-mounted charging port 20 located on a surface of a vehicle body and configured to be connected to the device to be charged 6.
Specifically, in the present embodiment, the identity authentication of the vehicle virtual key 3 by the vehicle-mounted wireless control unit 1 is completed in the background without user involvement. The vehicle-mounted wireless control unit 1 establishes a wireless communication connection with the vehicle virtual key 3 through a short-range wireless communication technology, the common short-range wireless communication technology includes bluetooth, ultra wide band, ZigBee, Wi-Fi, and the like, the embodiment does not limit the specific short-range wireless communication technology, but from the viewpoint of cost and applicability, the vehicle-mounted wireless control unit 1 of the embodiment is preferably a vehicle-mounted bluetooth control unit, and the vehicle-mounted bluetooth control unit 1 is taken as an example for description hereinafter.
The vehicle virtual key 3 is automatically connected with the vehicle-mounted Bluetooth control unit 1 through Bluetooth, the vehicle-mounted Bluetooth control unit 1 performs identity verification, and if the vehicle virtual key passes identity authentication, the legal vehicle virtual key 3 is positioned around the vehicle; otherwise, if the identity authentication is not passed, the fact that no legal vehicle virtual key exists around the vehicle is indicated. Thus, the vehicle-mounted bluetooth control unit 1 transmits two types of generated authentication results, that is, authentication pass or authentication fail, to the vehicle body network 4, specifically, the vehicle body network 2 in the present embodiment is a vehicle body CAN network (hereinafter, the vehicle body CAN network 4 is also described as an example).
When the device to be charged 6 is connected to the in-vehicle charging port 20, the in-vehicle charging control unit 2 starts timing. Meanwhile, the vehicle-mounted charging control unit 2 acquires an authentication result sent by the vehicle-mounted Bluetooth control unit 1 from the vehicle body CAN network 4, and if the authentication result is that the authentication is passed, a first charging mode is executed to charge the device to be charged; and if the authentication result is that the authentication is not passed, executing a second charging mode to charge the equipment to be charged. Specifically, the first charging mode is to stop timing, charge the device to be charged 6 indefinitely until the electric quantity of the device to be charged is full or the device to be charged 6 is disconnected from the vehicle-mounted charging port 20; the second charging mode is to stop charging the device to be charged 6 after the time reaches the emergency charging time period, that is, the charging time of the second charging mode is shorter than that of the first charging mode. Therefore, the vehicle-mounted charging control unit 2 further includes a timing module, configured to start timing when the device to be charged 6 is connected to the vehicle-mounted charging port 20, and stop timing when the vehicle-mounted charging control unit 2 receives an authentication result that the authentication is passed, or report when the vehicle-mounted charging control unit 2 receives an authentication result that the authentication is not passed until the emergency charging time period expires, and the vehicle-mounted charging control unit 2 stops charging the device to be charged accordingly.
Further, after the vehicle-mounted charging control unit 2 stops charging the device to be charged, the timing module will start the charging prohibition period, that is, the charging cannot be performed during the timing of the charging prohibition period, the charging can be performed again only after the expiration of the charging prohibition period, and the device to be charged 6 must be re-connected to the vehicle-mounted charging port 20.
As can be seen from the above description, the present embodiment provides a shared charging scheme when the vehicle is outside the vehicle and the vehicle is not powered up:
1. if the vehicle-mounted bluetooth control unit 1 passes the identity authentication of the vehicle virtual key 3, which indicates that the legal vehicle virtual key 3 is around the vehicle, at this time, the vehicle-mounted charging control unit 2 may charge each device to be charged 6 without time limitation, the vehicle-mounted charging port 20 becomes a shared charging port, and charging may be achieved without powering on the vehicle or entering the vehicle, and the charging current flows as shown by a solid arrow in fig. 1.
2. If the vehicle-mounted bluetooth control unit 1 fails to authenticate the vehicle virtual key 3, which indicates that the valid vehicle virtual key 3 is not located around the vehicle, the vehicle-mounted charging control unit 2 can still perform emergency charging for each device to be charged 6, the vehicle-mounted charging port 20 becomes a shared emergency charging port, and the charging current flows as shown by a solid arrow in fig. 1. The emergency charging is time limited and the charging function will stop after the emergency charging period expires.
It should be noted that, in order to facilitate connection between the device to be charged 6 and the vehicle-mounted charging port 20, in this embodiment, the vehicle-mounted charging port 20 is located on the surface of the vehicle body and does not only mean that the vehicle-mounted charging port is located on the surface of the vehicle body or protrudes from the surface of the vehicle body, but also includes any position on the vehicle body where the device to be charged 6 can be connected from the outside of the vehicle, for example, for the sake of simplicity in appearance, some vehicles are provided with a groove on the surface of the vehicle body, and the vehicle-mounted charging port 20 is located in the groove and then provided with a. As an example, referring to fig. 2, the in-vehicle charging port 20 may be provided near the trunk outside switch or at the vehicle body side rear, with the in-vehicle charging control unit 2 provided adjacent thereto. The in-vehicle charging port 20 may be various adapted charging ports, such as USB, Mini USB, Micro USB, Type C, Lighting, and the like.
The emergency charging period and the prohibited charging period may be configured and modified by a CAN diagnostic protocol as Data Identifiers (DIDs), and the present embodiment sets the emergency charging period to 10 minutes and the prohibited charging period to 30 minutes.
The vehicle battery 5 is electrically connected to the on-vehicle charging control unit 2 for supplying electric power to the device to be charged 6. Due to the limited capacity of the vehicle battery 5, feeding may occur if it is used for charging the device to be charged 6 all the time. For this reason, the in-vehicle charging control unit 2 of the present embodiment will also detect the voltage of the vehicle battery 5 in real time, and stop charging the device to be charged 6 if it is detected that the voltage of the vehicle battery 5 is lower than a predetermined voltage threshold. The predetermined voltage threshold may also be configured and modified as DID by CAN diagnostic protocol, with the present embodiment setting the predetermined voltage threshold to 10V. When the voltage of the vehicle battery 5 is lower than the predetermined voltage threshold for some reason, the vehicle-mounted charging port 20 can also serve as an interface for charging the vehicle battery 5, the vehicle battery 5 being charged by the external power supply 7, and the charging current flowing as indicated by the broken-line arrow in fig. 1.
In this embodiment, the vehicle virtual key 3 is a Portable electronic product with a conventional vehicle key function, such as a mobile phone, a Portable Device (PAD), and the like, and is generally implemented by loading and unloading a vehicle virtual key Application (APP) on and from the mobile phone and the PAD and installing the APP. The registration and pairing process of the vehicle virtual key 3 and the vehicle bluetooth control unit 1 is shown in fig. 3, taking downloading and installing the vehicle virtual key application in a mobile phone as an example:
firstly, after a mobile phone to be registered downloads and installs a vehicle virtual key application, binding registered vehicle information is written in through the vehicle virtual key application, and the mobile phone end vehicle virtual key application starts to receive a pairing request through Bluetooth communication.
At the vehicle-mounted Bluetooth end, a vehicle diagnosis instrument is used for connecting a registered vehicle, the vehicle-mounted Bluetooth control unit 1 is used for diagnosing the safety level authentication, and the information of the mobile phone to be registered is written in; the vehicle-mounted bluetooth control unit 1 then broadcasts the random number and the vehicle Identification code vin (vehicle Identification number).
The mobile phone end virtual key application verifies the received broadcast data, namely compares the broadcast data with the written registered vehicle information, and if the verification is passed, the mobile phone end virtual key application encrypts the received broadcast data by using a default key and sends the encrypted broadcast data to the vehicle-mounted Bluetooth control unit 1.
The vehicle-mounted Bluetooth control unit 1 verifies data which is sent by the application of the virtual key of the mobile phone end and encrypted by a default key, confirms whether the data is successful, writes relevant registration information of the mobile phone if the data is successful, registers the mobile phone into a legal vehicle virtual key, and sends a primary encryption key and a secondary encryption key; if the confirmation is unsuccessful, the random number and vehicle VIN code continue to be broadcast.
And after receiving the primary encryption key and the secondary encryption key, the virtual key application at the mobile phone end performs safe storage, thereby completing registration, and the vehicle-mounted Bluetooth end exits the diagnosis service mode.
After the registration of the legal vehicle virtual key is completed according to the above process, the vehicle bluetooth control unit 1 performs identity authentication on the connected vehicle virtual key, and the process is as follows:
the vehicle-mounted Bluetooth control unit 1 broadcasts a random number and a vehicle VIN code in the coverage range;
the mobile phone end virtual key application receives the broadcast random number and the vehicle VIN code, uses a primary encryption key for pairing, and then returns the paired key to the vehicle-mounted Bluetooth control unit 1;
the vehicle-mounted Bluetooth control unit 1 also adopts a primary encryption key for the broadcast random number and the vehicle VIN code, compares the primary encryption key with data returned by the application of the virtual key at the mobile phone end, passes the authentication if the comparison is successful, and fails the authentication if the comparison is unsuccessful.
The authentication result shows that the vehicle is a legal vehicle virtual key, and the vehicle-mounted charging control unit 2 can execute a first charging mode on the device to be charged 6; the authentication failure indicates an illegal vehicle virtual key, and the in-vehicle charging control unit 2 executes the second charging mode for the device to be charged 6.
The registration and authentication process can make the scheme of the vehicle virtual key simpler and lower in cost.
A typical application scenario of the embodiment of the present invention is that when an owner drives a car and plays with a friend in the field and the electric quantity of a mobile phone is reduced and charging is required, if the mobile phone of the owner (which is registered with the car) is within the coverage of the bluetooth control unit of the car, the bluetooth communication connection is established with the bluetooth control unit 1 through the virtual key application of the owner, and the bluetooth control unit 1 performs identity authentication on the mobile phone and outputs the authentication result to the car body network 4. Under normal conditions, the authentication results generally are that the authentication is passed, the vehicle-mounted charging control unit 2 charges the device to be charged 6 according to the first charging mode, and the device to be charged 6 at this time may be a mobile phone of a vehicle owner or a mobile phone of another person. If the mobile phone of the vehicle owner is not around the vehicle and the emergency charging is needed, an authentication result that the authentication is not passed is generated according to the identity authentication process, the vehicle-mounted charging control unit 2 charges the device to be charged 6 according to the second charging mode, namely the emergency charging time is up, and the device to be charged can be charged without opening a vehicle door and without waking up the vehicle and powering on due to the fact that the vehicle-mounted charging control unit is connected to a vehicle body network.
Corresponding to the first intelligent vehicle-mounted charging device in the embodiment of the invention, the second embodiment of the invention provides an intelligent vehicle-mounted charging method, which comprises the following steps:
establishing wireless communication connection with the vehicle virtual key, performing identity authentication on the vehicle virtual key, and outputting an authentication result to a vehicle body network;
and charging the equipment to be charged connected to the vehicle-mounted charging port through the vehicle-mounted charging port on the surface of the vehicle body according to the authentication result acquired from the vehicle body network and the corresponding charging mode.
When the obtained authentication result is that the authentication is passed, charging the equipment to be charged according to a first charging mode; when the obtained authentication result is that the authentication is not passed, charging the equipment to be charged according to a second charging mode; the first charging mode is specifically charging the equipment to be charged in an unlimited time until the electric quantity of the equipment to be charged is full or the equipment to be charged is disconnected from the vehicle-mounted charging port; the second charging mode is specifically to stop charging the device to be charged after the emergency charging duration is reached.
And the second charging mode also comprises the step of starting the timing of the charging forbidding time length after the charging of the equipment to be charged is stopped, and the rechargeable battery cannot be charged again during the timing of the charging forbidding time length.
Wherein, the process of establishing wireless communication connection with the vehicle virtual key and performing identity authentication comprises the following steps:
the vehicle-mounted terminal broadcasts the random number and the vehicle identification code;
the vehicle virtual key receives the broadcast random number and the vehicle VIN code, uses a primary encryption key for pairing and then returns the broadcast random number and the vehicle VIN code to the vehicle-mounted end;
and the vehicle-mounted terminal adopts a primary encryption key for the broadcast random number and the vehicle VIN code, compares the primary encryption key with data returned by the vehicle virtual key, passes the authentication if the comparison is successful, and fails the authentication if the comparison is unsuccessful.
