[0002] Traditional PEPS systems currently on the market typically have a separate controller responsible for collecting RF signals, processing them, implementing algorithmic positioning, and transmitting and receiving CAN signals to control the vehicle and transmit information. However, this system solution is highly coupled between the controller hardware and software, and algorithm development is heavily dependent on hardware status, making agile development impossible. In an era of rapidly accelerating software iteration, this solution is no longer adaptable.

[0003] In addition, the keyless entry system requires key positioning. With the popularization of neural networks, positioning accuracy has increased significantly, but at the same time, the algorithm has put forward higher requirements on chip computing power. In this case, the microcontroller used in the traditional PEPS controller is difficult to meet the computing power requirements of the neural network, and replacing the chip will also bring very high costs.

[0041] The following describes some of the various embodiments of the present invention, which are intended to provide a basic understanding of the present invention, but are not intended to identify the key or decisive elements of the present invention or to limit the scope of protection.

[0042] For the purpose of brevity and illustration, the principles of the present invention are described herein primarily with reference to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to and can be implemented in all types of keyless entry and start systems and keyless entry and start methods, and that any such changes do not depart from the true spirit and scope of this patent application.

[0043] Moreover, in the following description, reference is made to the accompanying drawings, which illustrate specific exemplary embodiments. Electrical, mechanical, logical, and structural changes may be made to these embodiments without departing from the spirit and scope of the present invention. In addition, although a feature of the present invention is disclosed in conjunction with only one of several embodiments, it may be desirable and / or advantageous to combine this feature with one or more other features of other embodiments as may be desired and / or advantageous for any given or identifiable function. Therefore, the following description should not be regarded in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.

[0044] Terms such as “having” and “including” indicate that in addition to the units (modules) and steps directly and clearly stated in the specification and claims, the technical solution of the present invention does not exclude the situation where it has other units (modules) and steps that are not directly or clearly stated.

[0045] Figure 1 FIG. 1 is a block diagram showing the structure of a keyless entry and start system according to an embodiment of the present invention.

[0046] like Figure 1 As shown, a keyless entry and start system according to an embodiment of the present invention includes:

[0047] Multiple sensors (i.e., BTAs) 100 for collecting service data;

[0048] a central module 200, configured to perform data exchange with the plurality of sensors and generate corresponding control instructions based on the service data received from the plurality of sensors; and

[0049] The controller 300 is configured to receive the control instruction from the central module and execute corresponding control actions based on the control instruction.

[0050] Preferably, a plurality of sensors 100 , a central module 200 , and a controller 300 are disposed in a vehicle, wherein the sensor 100 is capable of communicating with the mobile terminal 400 .

[0051] exist Figure 1 In the example, four sensors 100 are provided. The present invention does not limit the number of sensors 100. The multiple sensors 100 communicate with the central module 200, for example, via CAN. The central module 200 communicates with the controller 300, for example, via CAN. The controller 300 in the present invention can include various controllers within the vehicle, such as the BCM (body control module) and the DCM (door control module), which are not listed here.

[0052] In addition, as another example, the separate provision of the controller 300 may be omitted, and the function of “receiving the control instruction and executing the corresponding control action based on the control instruction” performed by the controller 300 may be integrated into the central module 200 .

[0053] In the present invention, the sensor 100 is the main body for performing wireless communication, and the wireless communication technology mainly used in the present invention is Bluetooth technology or UWB technology.

[0054] Ultra Wide Band (UWB) technology is a wireless carrier communication technology that transmits data using nanosecond-scale, narrow, non-sinusoidal pulses rather than sinusoidal carrier waves. Therefore, it occupies a very wide spectrum. UWB technology offers advantages such as low system complexity, low transmitted signal power spectral density, insensitivity to channel fading, low interception capability, and high positioning accuracy. It is particularly suitable for high-speed wireless access in dense multipath environments, such as indoor locations. Because UWB technology can also use ToF (Time of Flight) for ranging signals, positioning accuracy can reach over ten times that of traditional field strength ranging technologies.

[0055] In the present invention, the main functions of the sensor 100 include but are not limited to:

[0056] The Bluetooth underlying protocol stack is responsible for establishing a connection and communicating with the mobile terminal 400;

[0057] Obtain positioning data related to positioning through Bluetooth RSSI or UWB ranging; and

[0058] Positioning data, authentication data, Bluetooth communication data, etc. are provided as service data to the central module 200 via the CAN network.

[0059] In the present invention, as an example, each of the plurality of sensors 100 has a short-range communication function, while the central module 200 does not have a short-range communication function.

[0060] The central module 200 integrates the main logic and algorithms of the keyless entry system. Its main body can be a central computing platform or a domain controller. The main functions implemented by the central module 200 include but are not limited to:

[0061] Communicate with the sensor 100 via the CAN network;

[0062] Receive services provided by the sensor 100, such as positioning services, authentication services, Bluetooth communication data, etc.;

[0063] Integrated positioning algorithms and logic strategies; and

[0064] Integration with various domain controller algorithms.

[0065] The second item, "integrated positioning algorithms and logic strategies," can also be referred to as software upscaling or positioning algorithm upscaling. Specifically, in this invention, the positioning algorithm and positioning data are separated, with the positioning algorithm placed in the central module 200 and the positioning data stored in the sensor 100. This upscaling of the positioning algorithm leverages the powerful computing power of the domain controller or central computing platform, using, for example, deep learning algorithms, to achieve higher positioning accuracy. Furthermore, this approach offers greater scalability. Based on the services provided by the sensor 100, it can be subsequently combined with other controllers within the vehicle to generate more functions and applications.

[0066] In addition, by utilizing the third item mentioned above, "integration with various domain controller algorithms", more advanced functions can be realized based on services, such as big data collection, digital key sharing, AR applications, artificial intelligence algorithm positioning, etc.

[0067] Here, the above-mentioned positioning algorithm and positioning data separation are further explained in detail.

[0068] First, it is desirable to ensure that the positioning data acquired by the sensor 100 and transmitted to the central module 200 is authentic, to prevent third-party devices from interfering with data acquisition or illegally profiting from it. Therefore, to ensure the security of transmitted data, AES encryption is preferably performed during the data acquisition process, with the key distributed from the cloud. This ensures that the data collected by each vehicle cannot be decrypted without the key.

[0069] Secondly, it is also desirable to ensure real-time data collection and analysis. This is because the CAN bus itself has high latency, coupled with Bluetooth latency and potential delays in response from various modules. To address this issue, the present invention proposes that transmitted data be packaged and transmitted according to its intended purpose. For example, field strength data is set as the first priority to ensure that the positioning function is prioritized and effective. Authentication data can have a lower priority, but authentication can begin after Bluetooth connection is established. A window exemption period is provided after successful authentication to prevent delays caused by repeated authentication and inefficient data transmission.

[0070] Next, let's discuss the sleep and wakeup management of data collection and analysis functions. In the prior art, traditional integrated modules operate simultaneously with data collection and analysis. This means that when the entire vehicle enters sleep mode after being locked, the positioning function is completely disabled. In this invention, by separating the positioning algorithm from the positioning data, timely wakeup from sleep mode is possible. For example, even if the central module is not operating or is functioning as a slave node, data collection using sensors (e.g., signal strength information) continues, and basic threshold judgments and customized wakeup sources are performed. Once a fuzzy judgment is made that a mobile terminal is approaching, the master node can be instantly awakened for the next step of high-precision positioning.

[0071] Furthermore, regarding OTA (Over-the-Air) updates and iterations of algorithms and functions, existing technologies require sequentially refreshing all four sensors to update the software of traditional modules. However, with algorithm integration, the core and acquisition areas can be separated, allowing over 80% of algorithm and function updates to be completed by simply updating the central module, eliminating the need to refresh the remaining four sensors. For example, with four sensors, refresh time can be reduced by four times compared to traditional methods, resulting in a better user experience.

[0072] Furthermore, many protocols defined for central computing in the computer world, like TCP / IP, can only deliver as much data as possible, but cannot guarantee data integrity. Consequently, network lags, insufficient memory, and reboots are common in the computer world. However, unlike in the computer world, in vehicle control, the onboard central computer can hardly tolerate even a few reboots or network lags.

[0073] Secondly, although the present invention only uses the seemingly traditional "centralization", it actually still does some "marginalization" processing in the present invention, and does not completely centralize other redundant logics, such as unlocking, lighting control, etc., that is, only a part of the positioning-related algorithms is statically isolated, and the loss of other logic or system occupancy will not affect the central module 200 in the present invention.

[0074] Furthermore, in the present invention, the central module 200 is implemented by a central computing platform or domain controller, representing a fusion of computer technology and vehicle control. First, if positioning algorithms are integrated into multiple sensors, traditional Bluetooth modules are limited by computational constraints and cannot perform functions such as digital key sharing or advanced positioning. Furthermore, if positioning is fully centralized, the Bluetooth module and other modules will inevitably interact. Any problems could result in a startup failure at best, or even unexpected failures.

[0075] Therefore, the "central module 200" in this invention is a module between a "node" and "fully centralized." It ensures system independence and robustness while also expanding application cases to a certain extent, enabling functionality unattainable with current technologies. Furthermore, in the event of a system failure, the central module 200 can find a system backup solution as long as the Bluetooth connection remains intact.

[0076] On the other hand, in the present invention, all sensors 100 have master-slave integration capabilities, that is, all sensors can connect to the mobile terminal 400 and transmit valid data. Being master-slave integration means that the sensor 100 can act as both a master device and a slave device at the same time.

[0077] As an example, the central module 200 may designate one of the multiple sensors 100 as a master node, replacing the central module in performing functions. In this case, the remaining sensors 100 are slave nodes, and the master sensor and the slave sensors can exchange data. Of course, as another example, the central module 200 itself may also serve as a master node, in which case the multiple sensors 100 serve as slave nodes.

[0078] In the present invention, it can be set that the master node has the authentication and authorization functions while the slave nodes do not have the authentication and authorization functions.

[0079] Here is an example to illustrate that the sensor 100 works as a master node.

[0080] For example, in the prior art, only the central module can send information, and the central module is set inside the vehicle. When there is metal obstruction, it cannot connect to other Bluetooth devices for positioning, such as the Bluetooth on the charging pile. In this case, if the solution of the present invention is used, the sensor on the B-pillar of the car door can be "temporarily" switched from a node to a master node. For example, when the user unplugs the charging gun, although the charging gun cannot connect to the master node inside the vehicle due to the shielding of the car body, it can connect to the sensor on the B-pillar. At this time, the gun unplugging information can be obtained through the sensor on the B-pillar for Bluetooth authentication, and some new functions can be executed, such as automatically opening the charging port cover. In this way, the solution of the present invention can appoint the corresponding node (sensor) as the master node according to different working conditions. As a result, the keyless entry and start system and the keyless entry and start method can meet the needs of more application scenarios.

[0081] Next, a keyless entry and start system and a keyless entry and start method according to an embodiment of the present invention will be described.

[0082] Figure 2 FIG. 1 is a block diagram showing a keyless entry and start system according to an embodiment of the present invention.

[0083] like Figure 2 As shown, a keyless entry and start system according to an embodiment of the present invention includes:

[0084] The sensor 10 is used to collect positioning data from the mobile terminal 40;

[0085] The central module 20 is configured to perform data exchange with the sensor 10 and generate corresponding control instructions based on the positioning data received from the sensor 10; and

[0086] The vehicle body controller 30 is configured to receive the control instructions from the central module 20 and execute corresponding control actions based on the control instructions.

[0087] The sensor 10 and the central module 20 are connected to each other through the CAN communication, and the central module 20 and the vehicle body controller 30 are connected to each other through the CAN communication.

[0088] The sensor 10 has a short-range communication function. In this embodiment, the sensor 10 is implemented by a Bluetooth module, while the central module 20 does not have a short-range communication function. The sensor 10 has a master-slave capability, that is, the sensor 10 can connect to the mobile terminal 40 and transmit valid data.

[0089] A keyless entry and start system and a keyless entry and start method according to an embodiment of the present invention include the following steps:

[0090] When the mobile terminal 40 enters the connection range of the vehicle-side sensor 10, the sensor 10 is responsible for establishing a Bluetooth connection with the mobile terminal 40 and continuously obtaining the signal strength of the mobile terminal, namely RSSI ( Figure 2 ), and provides the signal strength information to the central module 20 as a positioning service via the CAN network in a packaged manner ( Figure 2 S2 in );

[0091] After receiving the positioning service from the sensor 10, the central module 20 starts the positioning algorithm process, and the sensor 10 continuously locates the position of the mobile terminal 40. As an example, when the mobile terminal 40 is located within a threshold range (e.g., 1.5 meters) close to the vehicle, the central module 20 will determine whether the current vehicle state meets the proximity unlocking condition. If so, the central module 20 will send an unlocking request as a control instruction to the body controller 30 ( Figure 2 in S3).

[0092] Here, the unlock request is listed as a control instruction. This is only an example. In the present invention, the control instruction can be a control instruction for multiple functions, and each function control instruction can correspond to a different distance threshold. For example, there can be multiple distance thresholds. In addition, the body controller 30 also feeds back the status of the door to the central module 20 ( Figure 2 The central module 20 also feeds back the positioning result to the sensor 10 (S4 in FIG. Figure 2 The sensor 10 also feeds back the positioning result 40 to the mobile terminal ( Figure 2 S6 in ).

[0093] The present invention also provides a computer-readable medium having a computer program stored thereon, wherein the computer program implements the above-mentioned keyless entry and starting method when executed by a processor.

[0094] The present invention also provides a computer device, comprising a storage module, a processor, and a computer program stored on the storage module and executable on the processor, wherein the processor implements the keyless entry and start method when executing the computer program.

[0095] The present invention also provides a vehicle, characterized by being equipped with the above-mentioned keyless entry and start system.

[0096] As described above, the keyless entry and start system and method, as well as the vehicle, according to the present invention, achieve hardware and software separation and enhance development flexibility. Furthermore, the keyless entry and start system and method of the present invention offer enhanced scalability. Based on the services provided by the sensors, they can be subsequently combined with other controllers within the vehicle to generate more functions and applications. Furthermore, by integrating with various domain controller algorithms, they can implement more advanced service-based functions, such as big data collection, digital key sharing, augmented reality applications, and artificial intelligence algorithm positioning.

[0097] The above examples primarily illustrate the keyless entry and start system and method, as well as the vehicle, of the present invention. While only certain specific embodiments of the present invention have been described, those skilled in the art will appreciate that the present invention may be implemented in numerous other forms without departing from its spirit and scope. Therefore, the examples and embodiments presented are to be considered illustrative rather than restrictive, and the present invention may encompass various modifications and substitutions without departing from the spirit and scope of the present invention as defined in the appended claims.
