Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a vehicle key matching method according to an embodiment of the present invention. As shown in fig. 1, the vehicle key matching method includes: the vehicle state is set to a key matching state, and the vehicle key information is written to the remote control portion of the vehicle key.

The embodiment of the invention and the automobile key are taken as an example to explain the vehicle key matching method. The car key generally includes a mechanical key section and a remote control key section.

For the mechanical key part, there is a mechanical tooth code. After an automobile is manufactured, a password plate is arranged for an automobile key of the automobile. The combination card records the mechanical tooth code of the automobile key of the vehicle. If the automobile key is lost, the owner can obtain the mechanical tooth code of the automobile key of the vehicle through the code plate.

Since the mechanical key part generates the mechanical tooth code through the arrangement of the mechanical pole teeth (such as the height and the like of the pole teeth), the mechanical tooth code can be obtained by looking at the mechanical key picture. For example, after a car owner takes a car key of a vehicle, a picture is taken of a mechanical key part of the car key, and a layout structure of pole teeth of the mechanical key part is obtained. Fig. 2 is a block diagram of an exemplary mechanical tooth of a mechanical key, and as shown in fig. 2, a plurality of mechanical pole teeth are distributed on a mechanical key portion of an automobile key. The mechanical pole teeth have different shapes and heights, and the spacing between the mechanical pole teeth is different, so that the layout format forms the mechanical tooth code. As can be seen from fig. 2, there are 9 mechanical teeth, and the relief grade data of the 9 mechanical teeth is "2-3-4-4-4-2-1-1-2" (from left to right) in accordance with the relief state of the mechanical teeth.

After the picture of the mechanical key is obtained by photographing, the layout data of the mechanical teeth can be obtained by analyzing the picture of the mechanical key, and the mechanical tooth password of the automobile key of the vehicle can be obtained. According to fig. 2, the obtained mechanical key code is: the mechanical key part has 9 mechanical teeth, and the height fluctuation grade data of the mechanical teeth of the 9 mechanical teeth from left to right is 2-3-4-4-4-2-1-1-2'.

And after the mechanical tooth code of the mechanical key part is obtained, cutting a key blank by a mechanical key configuration device based on the mechanical tooth code to complete the configuration of the mechanical key.

In the embodiment of the invention, the mechanical key configuration device can be a numerical control key machine.

The touch display 1 is used for inputting or displaying a mechanical password. Illustratively, the owner of the vehicle obtains the mechanical tooth code of the automobile key of the vehicle through image analysis of the code plate or the mechanical key of the vehicle, for example, the height fluctuation grade data of the mechanical teeth of 9 mechanical teeth from left to right is '2-3-4-4-4-2-1-1-2'. Then, the mechanical tooth code is input into the numerical control key machine through the touch display 1. Further, the numerical control key machine may have an image analysis device, and the mechanical key code is obtained by analyzing the image of the mechanical key and displayed on the touch display 1. In order to prevent the problems of input errors or image analysis errors and the like, the user can modify the obtained mechanical tooth code.

The emergency button 2 is used for realizing the control of emergency. For example, in the key preparation process, an unexpected situation occurs, for example, a situation of injury to a person, a situation of wrong mechanical key code, and the like, and a user can cut off the power supply of the data key machine by pressing the emergency button 2 to emergently stop the key preparation of the data key machine, so that the injury is effectively prevented from being expanded when the unexpected injury occurs.

The key engraving box 3 is used for engraving a mechanical key. In the embodiment of the invention, the key blank can be carved by the key preparation control key carving box 3 according to the obtained mechanical tooth password. For example, a virtual key for "key allocation" may be displayed on the middle touch display 1, and in the using process of the user, the key allocation key is touched to realize engraving of the key blank, and finally, allocation of the mechanical key is completed.

For the remote control key section, a car key identification number ID is recorded. After the automobile is manufactured, an automobile key ID is distributed to the automobile, in the using process of an automobile owner, the automobile key ID is sent to the automobile through a remote control key of an automobile key, the automobile receives the automobile key ID and then compares the automobile key ID with the automobile key ID recorded by the automobile owner, and under the condition of consistency, the automobile door is opened or closed.

After the automobile key is lost, the embodiment of the invention can more conveniently acquire the original automobile key ID number of the automobile in the following mode, thereby realizing the matching of the remote control key part.

The mechanical key configured in the embodiment of the invention is used for opening the door of the automobile, so that the matching step of the remote control key part is entered.

The chip type of the car key needs to be determined first. Since different types of automobiles have different types of automobile key chips, there is a possibility that the remote control key section cannot be matched if the type of the automobile key chip does not correspond to the automobile vehicle. In the embodiment of the invention, the chip type of the automobile key to be matched can be confirmed by key chip reading and writing machines such as a chip copying machine, and the automobile key chip type can be inquired through the VIN code of the automobile in a key-free scene.

The chip copying machine in the embodiment of the invention has the main function of determining the chip type of the automobile key, and is convenient for finding blank chips of the same type subsequently and writing key data.

At this time, the vehicle needs to be turned to a vehicle key matching state. In the embodiment of the invention, the automobile can be adjusted to the automobile key matching state through the automobile state control equipment such as an automobile decoder. For example, a car decoder may be inserted into an OBD (On Board Diagnostics) interface of the car to decode a driving computer, and the car decoder issues a command to turn the car to a car key matching state.

Fig. 5 shows a block diagram of a car decoder according to an embodiment of the invention. As shown in fig. 4, the car decoder according to the embodiment of the present invention mainly includes an OBD interface 7, an OBD data extension line 8, and a flat panel display 9.
