[0011] Figure 1 Schematic diagram of the vehicle-mounted control system of the present invention. Implementation

[0012] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0013] The present invention provides a vehicle-mounted control system, comprising: a smart accessory 1, a bracket, an unlocking module, etc.

[0014] The bracket is fixed inside the vehicle and is used to insert and stabilize the smart accessory 1. Generally, the bracket is arranged above the instrument panel. The smart accessory 1 has an interactive screen 11, a communication interface, a digital key and a processor.

[0015] The interactive screen 11 can be operated by the vehicle user to complete the interaction with the vehicle, including but not limited to adjusting the mirrors, adjusting the seats, adjusting the lights, air conditioning, etc. After the smart accessory 1 is inserted into the bracket, the interactive screen 11 faces the driver.

[0016] The digital key is integrated in the smart accessory 1. The digital key has two parts, hardware and software. The hardware includes a first antenna coil, such as an NFC transmitting coil. The software is a program that controls the hardware to output corresponding digital signals. The processor can process the data of the smart accessory 1 itself and realize its own functions. In addition, it can also control the vehicle with the cooperation of the communication interface, mainly through the communication interface to communicate with the vehicle main control system, and transfer the realization of some functions from the vehicle's processor, such as configuring the air conditioning temperature, turning on driving video, etc. This can reduce the working intensity of the vehicle processor, thereby reducing the requirements for the vehicle chip. Generally, functions that are less related to driving safety are transferred out.

[0017] Furthermore, the smart accessory 1 also has a first camera, and after the smart accessory 1 is inserted into the bracket, the first camera faces the windshield. This structure allows the function of the driving recorder to be moved outward, and at the same time, the camera originally installed on the vehicle is also moved to the smart accessory 1.

[0018] The communication interface is one of Bluetooth, Wi-Fi, near field communication, cellular network, and wiring harness interface.

[0019] The unlocking module is located at the bottom of the bracket and performs encrypted communication with the digital key to unlock the vehicle. After the unlocking module matches and unlocks the digital key, the interactive screen 11 displays interactive content related to the vehicle settings.

[0020] The digital key usually communicates with the unlocking module using near field communication (NFC) technology or Bluetooth technology.

[0021] For example, when near field communication is used, it mainly includes a second antenna coil (NFC receiving coil) and an antenna PCB board. The second antenna coil communicates with the first antenna coil to complete the verification and unlock the vehicle. As a short-range wireless communication technology, the distance between the smart device 1 and the unlocking module is usually very short (usually no more than a few centimeters). Both parties in communication must also be equipped with an NFC chip. During the communication process, the user can establish a connection between the smart device 1 by bringing it close to the unlocking module on the vehicle, which can be an NFC reader. Once the connection is established, the digital key information can be transmitted to the vehicle unlocking module to complete the unlocking operation. NFC communication has a high level of security because it requires a very close distance to communicate, reducing the possibility of remote attacks.

[0022] In addition, Bluetooth can also be used. Bluetooth technology allows wireless connection to be established over a long distance. Both the unlocking module and the smart device 1 are equipped with Bluetooth modules, and the connection is established through pairing. During the communication process, the user selects the unlock option in the application corresponding to the digital key on the smart device 1, and the application sends the unlock command to the vehicle unlocking module via Bluetooth to complete the unlocking operation.

[0023] The above-mentioned smart device 1 can be a mobile phone. In this case, the mobile phone can be used as a carrier of the digital key. The car owner configures the mobile phone as the digital key of the vehicle by installing a specific digital key application (i.e. the above-mentioned digital key software) on his mobile phone.

[0024] During authentication, the application uses the owner's biometric information (such as fingerprint recognition, facial recognition) or password to authenticate the owner, ensuring that only the legitimate owner can access the digital key function. It is usually configured by the mobile phone (smart accessory 1) so that the information on the digital key includes at least unlocking information, so that the unlocking module can obtain it and perform the unlocking operation.

[0025] The unlocking information of the digital key can be transferred between multiple mobile phones (smart accessory 1). The application allows the car owner to authorize other mobile phones as digital keys in the digital key system so that other users can use their mobile phones as digital keys for the vehicle. Encrypted communication is established between the application and the digital key system inside the vehicle to ensure the secure transmission of digital key information. The car owner can use the application to remotely unlock and lock the vehicle, as well as start or shut down the vehicle's engine.

[0026] All digital key information, including authorization information and authentication data, should be securely stored in the phone to prevent unauthorized access. The digital key system should be able to update authorization information in real time so that car owners can add or delete authorized users at any time.

[0027] The smart accessory 1 contains driving habit data. After the unlocking module matches and unlocks the digital key, the driving habit data is sent to the vehicle main control system via the communication interface.

[0028] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
