[0030] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0031] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0032] In addition, the terms "first", "second", "third", etc. included in the embodiments of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific number or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances. This is just a way of distinguishing objects with the same attributes when describing them in the embodiments of the present invention.

[0033] Furthermore, the vehicle involved in the embodiment of the present invention may be an internal combustion engine vehicle using an engine as a power source, a hybrid vehicle using an engine and an electric motor as a power source, an electric vehicle using an electric motor as a power source, or the like.

[0034] Figure 1 The following is a schematic diagram showing the main steps of the electronic license plate management method applied to the server provided by the embodiment of the present invention:

[0035] Step S101: receiving an application request for a temporary electronic license plate, wherein the application request includes a vehicle unique identifier and / or an occupant unique identifier.

[0036] Step S102: Generate a temporary electronic license plate with a valid time range based on the vehicle unique identifier and / or the occupant unique identifier.

[0037] Specifically, for vehicles that have not yet obtained a fixed license plate, or vehicles whose license plate numbers of fixed license plates are restricted in a certain time period, an embodiment of the present invention provides a temporary electronic license plate management method.

[0038] A server (eg, a cloud server, a license plate management server, a traffic management platform, etc.) is used to receive an application request for a temporary electronic license plate, wherein the application request includes a unique vehicle identifier and / or a unique occupant identifier.

[0039] The vehicle unique identifier is, for example, VIN (Vehicle Identification Number), CAL ID (Calibration Identification), etc., which is a unique identifier used to distinguish the vehicle. The occupant unique identifier is the identity identifier of the vehicle user (such as the owner) (such as ID card information, etc.). In an embodiment of the present invention, a temporary electronic license plate can be generated based on the vehicle unique identifier, or based on the occupant unique identifier, or a temporary electronic license plate can be generated based on the occupant unique identifier, or a temporary electronic license plate can be generated in combination with the vehicle unique identifier and the occupant unique identifier.

[0040] The temporary electronic license plate is a randomly generated string containing one or more numbers, letters, and characters (the length of the string can be set arbitrarily according to the display effect). It can be understood that the string of the temporary electronic license plate is unique and traceable.

[0041] Furthermore, the temporary electronic license plate has a valid time range; wherein the method for determining the valid time range of the temporary electronic license plate includes:

[0042] The first method is to determine the effective time range of the temporary electronic license plate of the vehicle according to the traffic conditions of the area where the vehicle is located. For example, according to the predicted congestion conditions (i.e., traffic conditions) of the roads in a certain area or a large area where the vehicle is located, determine the effective time range of the temporary electronic license plate so that the effective time range does not overlap with the congestion period.

[0043] The second method is to obtain the effective time range of the temporary electronic license plate from the application request. The vehicle can send a request for the effective time range based on the vehicle use demand. That is, the effective time range is carried in the application request for the temporary electronic license plate.

[0044] The third method: Combine the effective time range of the temporary electronic license plate obtained from the application request with the effective time range of the temporary electronic license plate obtained from the application request. When the effective time ranges of the two are different, use the priority strategy to select the effective time range of the temporary electronic license plate.

[0045] Specifically, the server can combine the effective time range obtained by the first method and the effective time range obtained by the second method. If the two effective time ranges are inconsistent, the server can use priority strategies or select larger values ​​(or smaller values) and other strategies to determine the effective time range of the temporary electronic license plate.

[0046] The effective time range can be any time length between 0.1 hours and 24 hours, and the present invention does not limit the specific value of the effective time range.

[0047] That is, after receiving the application request for the temporary electronic license plate, it further includes: determining the valid time range of the temporary electronic license plate according to the traffic conditions of the area where the vehicle is located; or, obtaining the valid time range of the temporary electronic license plate from the application request.

[0048] Before generating the corresponding temporary electronic license plate based on the vehicle unique identification and / or the occupant unique identification, it further includes: in the case where the vehicle unique identification and / or the occupant unique identification is encrypted information, decryption operation is performed on the encrypted information, the decrypted vehicle unique identification and / or the occupant unique identification is verified, and after the verification is passed, the step of generating a temporary electronic license plate with a valid time range based on the vehicle unique identification and / or the occupant unique identification is performed. Specifically, the vehicle can send the encrypted information generated based on the vehicle unique identification and / or the occupant unique identification as the data of the application request. After determining that the vehicle unique identification and / or the occupant unique identification is encrypted information, the server performs a decryption operation on the encrypted information, verifies the decrypted vehicle unique identification and / or the occupant unique identification, and after the verification is passed, the step of generating a temporary electronic license plate with a valid time range based on the vehicle unique identification and / or the occupant unique identification is performed. Among them, the encryption method is, for example, MD5. Verifying the vehicle unique identification and / or the occupant unique identification includes verifying the legitimacy and correctness of the identification.

[0049] Step S103: Sending a temporary electronic license plate to the vehicle, so that the vehicle displays the temporary electronic license plate on the outside of the vehicle within a valid time range, and the vehicle uses the temporary electronic license plate within a valid time range.

[0050] Specifically, the server sends the generated temporary electronic license plate to the vehicle that sent the application request, so that the vehicle displays the temporary electronic license plate on the outside of the vehicle within the effective time range, so that the vehicle uses the temporary electronic license plate within the effective time range. Among them, an electronic display module can be set on the outside of the vehicle, and the electronic display module can be set at the front, rear, side, etc. of the vehicle, and can also be retracted (retracted when the electronic license plate is not needed). The electronic display module is used to display the temporary electronic license plate.

[0051] The embodiment of the present invention generates temporary electronic license plates in real time, so that vehicles that cannot be driven on the road due to fixed license plates can use temporary electronic license plates within a valid time range, thereby improving the vehicle-using experience of passengers and improving the flexibility and efficiency of vehicle management.

[0052] Figure 2 The following is a schematic diagram showing the main steps of the electronic license plate management method for vehicles provided by the embodiment of the present invention:

[0053] Step S201: Acquire a unique identification of the vehicle, and / or acquire a unique identification of the passenger from a device of the vehicle user.

[0054] Specifically, the vehicle control module can be used to obtain the vehicle's unique identification (for example, VIN, CAL ID, etc.) from the vehicle's electronic control unit; and / or, obtain the occupant's unique identification (for example, ID card information) from the vehicle user's terminal device (for example, the owner's application client).

[0055] Step S202: Sending an application request for a temporary electronic license plate including a vehicle unique identifier and / or a passenger unique identifier.

[0056] Specifically, an application request for a temporary electronic license plate including a vehicle unique identifier and / or an occupant unique identifier is sent. It is understandable that the application request may also include a required validity time range; it may also be encrypted information of the vehicle unique identifier and / or the occupant unique identifier.

[0057] Step S203: receiving a temporary electronic license plate with a valid time range sent by the service end, and displaying the temporary electronic license plate on the outside of the vehicle within the valid time range, so that the vehicle uses the temporary electronic license plate within the valid time range.

[0058] Specifically, a temporary electronic license plate with a valid time range is received from a server, and the temporary electronic license plate is displayed on the outside of the vehicle within the valid time range, including: obtaining the valid time range corresponding to the temporary electronic license plate; calculating the remaining valid time based on the current time and the valid time range; determining the current effective status of the temporary electronic license plate according to the remaining valid time; when displaying the temporary electronic license plate on the outside of the vehicle, different display states are used to distinguish the current effective status, so as to identify the validity and remaining valid time of the temporary electronic license plate based on the display state. For example, the effective time range of the temporary electronic license plate "abcd1234" is 4 hours between 8:00 and 12:00; during the use of the temporary electronic license plate, the vehicle can calculate the remaining effective time based on the current time and the effective time range, for example, when the current time is 10 o'clock, the remaining effective time is calculated to be 2 hours, when the current time is 11 o'clock, the remaining effective time is calculated to be 1 hour, etc.; further, the display state can be used to distinguish the current effective state corresponding to the remaining effective time, for example, when the remaining effective time exceeds 2 hours or half of the effective time range, the background of the temporary electronic license plate is green, when the remaining effective time is less than 2 hours or less than half of the effective time range, the background of the temporary electronic license plate is yellow, when the remaining effective time is less than 1 hour or less than 3 / 4 of the effective time range, the background of the temporary electronic license plate is red, and when the effective time range is exceeded, the electronic display module does not display information or displays other non-temporary electronic license plate information. That is, the validity and remaining effective time of the temporary electronic license plate are identified based on the display state.

[0059] The embodiments of the present invention improve the vehicle-using experience of passengers and the flexibility of managing temporary electronic license plates by applying for and displaying temporary electronic license plates in real time and using display status (such as background color, font color, border color, flashing, etc.) to identify the validity and remaining validity period of the temporary electronic license plates.
