Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle instruments, and in particular to a method and system for information interaction between a motorcycle instrument and a smart phone. Background Art

[0002] With the continuous upgrade of motorcycle electronic features, the degree of electronic control is becoming increasingly advanced. Multifunctional, high-precision, highly sensitive, and intuitively readable electronic digital and image display LCD instruments are increasingly being used on motorcycles, further developing smart instruments. Car-mobile interconnection mapping, or vehicle-machine interconnection, involves projecting a mobile phone's screen onto the vehicle's onboard display, allowing users to operate navigation, video, music, games, and other functions on the phone through the display. The addition of car-mobile mapping makes it convenient to use the large screen inside the car to watch videos and use mobile navigation. The phone connects to the vehicle's central control system via USB, Wi-Fi, or Bluetooth, projecting the phone's operating interface onto the central control display. The driver can then operate the phone using the central control's physical buttons or voice commands.

[0003] A search revealed a Chinese utility model patent application numbered CN202120931042.2, which discloses a mobile phone-connected TFT motorcycle instrument. This overcomes the existing problem of motorcycle instruments being unable to connect to mobile phones. The instrument comprises a control module, a display module, a communication module capable of communicating with a mobile terminal, a power module, and a key module. The control module is connected to the display module, communication module, power module, and key module, respectively, and the communication module is connected to the mobile terminal. It can display vehicle speed, fuel level, and motorcycle status information, and can also connect to a mobile phone to display navigation, video, music, and other information on the phone.

[0004] Another example is a Chinese invention patent application with patent application number CN202311873972.7, which discloses a motorcycle instrument Bluetooth system, control method, connection method, and motorcycle. The system includes a first Bluetooth module, a second Bluetooth module, and a display module; the display module is connected to the first Bluetooth module and the second Bluetooth module respectively, and the display module includes interactive buttons that can call the functions of the first Bluetooth module and the second Bluetooth module; the first Bluetooth module and the second Bluetooth module are located on different Bluetooth chips; the first Bluetooth module is used to connect to a mobile device; and the second Bluetooth module is used to connect to headphones. This application realizes the simultaneous connection of a motorcycle instrument Bluetooth terminal with a mobile device and a headset, and the connection between the Bluetooth terminal and the two Bluetooth devices will not affect each other. At the same time, it realizes humanized Bluetooth call control and improves the user experience.

[0005] Although the existing motorcycle meters mentioned above can meet basic usage needs, they are mainly used to display basic vehicle status data such as speed, fuel level, mileage, etc., and cannot meet users' intelligent needs such as navigation, multimedia control, and call reminders. In the existing technology, some motorcycles try to connect to smartphones via Bluetooth, but there are the following problems:

[0006] 1. One-way communication: Only supports mobile phone audio playback control, and cannot project key mobile phone information (such as navigation and messages) to the instrument interface in real time.

[0007] 2. Poor compatibility: Different brands of mobile phones and motorcycle protocols do not match, resulting in limited functions.

[0008] 3. Insufficient safety: Information display lacks priority management, which may interfere with driving safety.

[0009] Therefore, there is an urgent need for an efficient, safe and highly compatible interaction method and system to achieve deep collaboration between motorcycle instruments and smartphones. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to provide a method and system for information interaction between a motorcycle instrument and a smart phone in response to the above-mentioned defects of the prior art, so as to solve the problems of low data transmission efficiency, protocol incompatibility, information display interfering with driving, and insufficient safety between the motorcycle instrument and the smart phone, thereby improving user experience and safety.

[0011] In order to solve the above technical problems, the technical solution of the present invention is:

[0012] A method for information interaction between a motorcycle instrument and a smart phone, comprising the following steps:

[0013] Step S1: Establishing a connection link between the motorcycle meter and the smartphone through a multi-mode communication module. After the motorcycle meter and the smartphone are paired, a unique binding code is generated and stored in a cloud server, supporting multi-device switching.

[0014] Step S2: parsing and converting the motorcycle CAN bus protocol and the smartphone operating system protocol through a protocol converter to achieve data format standardization;

[0015] Step S3: Dynamically divide the driving mode according to the vehicle speed, control the information display priority and interaction mode, and in the driving mode, the motorcycle instrument automatically blocks non-critical information according to the vehicle speed;

[0016] Step S4: Determine the driving behavior data using the gyroscope threshold, generate a safety score, and feed it back to the smartphone.

[0017] Preferably, in step S1, when the multi-mode communication module detects that the communication link is interrupted, it automatically switches to the cellular network for data backup transmission.

[0018] Preferably, in step S1, when the motorcycle instrument is started, the Bluetooth module, Wi-Fi module and NFC module are automatically activated, and the device identification signal is broadcast. The device identification signal is scanned by the smart phone, and the Bluetooth, Wi-Fi or NFC connection mode is selected according to the device type.

[0019] Preferably, in step S2, the protocol converter automatically analyzes the differences between the motorcycle CAN bus protocol and the smartphone operating system protocol, and generates a standardized data interface. The smartphone pushes navigation instructions, incoming call / message notifications, and music control instructions to the motorcycle instrument in real time through the standardized data interface; the motorcycle instrument transmits vehicle data such as vehicle speed, fuel level, fault code, etc. back to the smartphone through the standardized data interface.

[0020] Preferably, in the step S3, it also includes interrupting the current display interface when a vehicle fault is detected, popping up a red warning box on the full screen and synchronously triggering a vibration alarm on the smartphone.

[0021] Preferably, in step S3, the display control module is further used to divide the instrument interface into a navigation area, a notification area, and a vehicle status area. When the vehicle speed exceeds a preset threshold, non-emergency notifications are automatically shielded and only navigation and vehicle warning information are displayed.

[0022] Preferably, in step S3, when the vehicle speed is ≥30 km / h, the driving mode is automatically enabled: non-emergency notifications are shielded, only navigation and vehicle warning displays are retained, touch operations are delayed in response, and physical buttons or voice control are forced to be relied upon.

[0023] To solve the above technical problems, the present invention further provides a motorcycle instrument and smartphone information interaction system, comprising:

[0024] A motorcycle instrument panel, which uses a display controller to divide the instrument interface into navigation, notification, and vehicle status areas. It also uses gyroscope thresholds to determine driving behavior data, generate a safety score, and provide feedback to a smartphone.

[0025] A smartphone, used to scan the device identification signal and pair with the motorcycle instrument via Bluetooth, Wi-Fi, or NFC connection;

[0026] A multi-mode communication module is used to establish a connection link between the motorcycle instrument panel and the smartphone, generate a unique binding code and store it on the cloud server;

[0027] Protocol converter, used to parse and convert motorcycle CAN bus protocol and smartphone operating system protocol to achieve data format standardization;

[0028] The dynamic scheduling engine is used to optimize data transmission priorities based on reinforcement learning algorithms, dynamically divide driving modes according to vehicle speed, and control information display priorities and interaction methods.

[0029] Using the above-mentioned technical solution, the present invention provides a method and system for information interaction between a motorcycle instrument and a smartphone, which have the following beneficial effects: through multi-mode communication protocol adaptation, two-way data synchronization, dynamic priority scheduling, and security control mechanisms, deep collaborative operation between the two is achieved, expanding the intelligent functions of the motorcycle instrument and improving driving safety. This allows for efficient collaboration between the motorcycle instrument and smartphone, enhancing driving safety and user experience. Specifically, these include: 1. Improved communication efficiency: enabling two-way data exchange between smartphones and motorcycle instruments, expanding the intelligent functions of the instruments; 2. Enhanced safety: reducing driver distraction through information layering and dynamic adjustment of driving modes; 3. Expanded compatibility: supporting mainstream mobile phone operating systems and motorcycle communication protocols, reducing adaptation costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0036] like Figure 1 As shown, the method for information interaction between a motorcycle instrument and a smart phone includes the following steps:

[0037] Step S1: Establishing a connection link between the motorcycle meter and the smartphone through the multi-mode communication module. After the motorcycle meter and the smartphone are paired, a unique binding code is generated and stored in the cloud server, supporting multi-device switching;

[0038] Step S2: parsing and converting the motorcycle CAN bus protocol and the smartphone operating system protocol through a protocol converter to achieve data format standardization;

[0039] Step S3: Dynamically divide the driving mode according to the vehicle speed, control the information display priority and interaction mode, and in the driving mode, the motorcycle instrument automatically blocks non-critical information according to the vehicle speed;

[0040] Step S4: Determine the driving behavior data using the gyroscope threshold, generate a safety score, and feed it back to the smartphone.

[0041] It can be understood that in step S1, when the multi-mode communication module detects that the communication link is interrupted, it automatically switches to the cellular network for data backup transmission; when the motorcycle instrument is started, the Bluetooth module, Wi-Fi module and NFC module are automatically activated, and the device identification signal is broadcast. The device identification signal is scanned by the smartphone, and the Bluetooth, Wi-Fi or NFC connection method is selected according to the device type.

[0042] As you can understand, the communication link is established: When the motorcycle's instrument cluster is powered on, Bluetooth 5.2 (supports BLE), Wi-Fi 6E, and the cellular network module are simultaneously activated, broadcasting a handshake signal containing the device type, protocol version, and encryption public key. The smartphone uses a dedicated app to scan and select the optimal communication method (Bluetooth is prioritized when the distance is ≤5m, and Wi-Fi is enabled for high-speed data transmission). Phone → Instrument Cluster Data Flow: Navigation instructions (GPS coordinates, turn instructions) are transmitted via a low-latency channel (Wi-Fi) and displayed full-screen on the instrument cluster's main interface. Incoming call / message notifications are compressed and displayed as icons (maximum size 20×20 pixels) in the instrument cluster's sidebar. User-defined settings (such as unit switching) are synchronized via differential updates, transmitting only changed parameters. Instrument Cluster → Phone Data Flow: Vehicle status data (fuel level, tire pressure, fault codes) is sampled once per second, aggregated into data packets, and uploaded to the smartphone app. Driving behavior data (sudden acceleration, sudden braking) is determined by gyroscope thresholds (triggered when angular velocity ≥ 2 rad / s), generating a safety score that is fed back to the phone.

[0043] It can be understood that in step S2, the protocol converter automatically analyzes the differences between the motorcycle CAN bus protocol and the smartphone operating system protocol, generating a standardized data interface. The smartphone pushes navigation instructions, call / message notifications, and music control instructions to the motorcycle instrument in real time through the standardized data interface; the motorcycle instrument transmits vehicle data such as vehicle speed, fuel level, and fault codes back to the smartphone through the standardized data interface. Protocol conversion: The embedded protocol converter analyzes the motorcycle CAN bus protocol (such as J1939, ISO 15765) and the mobile phone operating system protocol (Android Auto, CarPlay) to generate a standardized JSON data stream. Data transmission uses double-layer encryption: AES-256 encryption is used at the link layer, and end-to-end encryption based on the elliptic curve cryptography (ECC) is added to the application layer.

[0044] It is understandable that in this step S3, when a vehicle fault is detected, the current display interface is interrupted, a red warning box pops up in full screen, and the smartphone vibration alarm is triggered simultaneously; the display control module is used to divide the instrument interface into a navigation area, a notification area, and a vehicle status area. When the vehicle speed exceeds a preset threshold, non-emergency notifications are automatically blocked, and only navigation and vehicle warning information are displayed; when the vehicle speed is ≥30km / h, the driving mode is automatically enabled: non-emergency notifications are blocked, only navigation and vehicle warning displays are retained, touch operations are delayed in response, and physical buttons or voice control are forced to be relied upon. It also includes emergency event preemption: when a vehicle fault is detected (such as engine overheating), the current display interface is interrupted, a red warning box pops up in full screen, and the smartphone vibration alarm is triggered simultaneously.

[0045] like Figure 2As shown, the motorcycle instrument and smartphone information interaction system includes:

[0046] Motorcycle instrument panel 1, which is used to divide the instrument panel interface into a navigation area, a notification area, and a vehicle status area through a display controller, and to determine driving behavior data through a gyroscope threshold to generate a safety score and feed it back to the smartphone;

[0047] Smartphone 2, used to scan the device identification signal and pair with the motorcycle instrument through Bluetooth, Wi-Fi or NFC connection;

[0048] Multi-mode communication module 3, used to establish a connection link between the motorcycle instrument and the smartphone, generate a unique binding code and store it in the cloud server;

[0049] Protocol converter 4, used to parse and convert the motorcycle CAN bus protocol and the smartphone operating system protocol to achieve data format standardization;

[0050] Dynamic Scheduling Engine 5 is used to optimize data transmission priorities based on reinforcement learning algorithms, dynamically divide driving modes according to vehicle speed, and control information display priorities and interaction methods.

[0051] It is understandable that after the user starts the motorcycle, the smartphone automatically connects to the motorcycle instrument via Bluetooth, NFC or WIFI. After the mobile navigation APP plans the route, the main screen of the instrument switches to full-screen navigation mode, and the vehicle speed and fuel level information are displayed on the right sub-screen. When the user receives an incoming call, the incoming call icon is displayed at the top of the instrument. The data transmission from mobile phone to instrument includes: Navigation information: After the mobile phone APP (such as Baidu CarLife) plans the route, the navigation instructions are pushed to the instrument in real time, supporting full-screen display or split-screen arrow prompts; Notifications and multimedia: Incoming calls and messages are prompted through the icon sidebar, and music playback control instructions are synchronized to the instrument physical buttons or touch interface; Custom settings: Users adjust the instrument display unit (such as kilometers / miles), clock format and other parameters through the mobile phone APP, and synchronize instantly after the settings are completed.

[0052] It can be understood that the multi-mode communication module 3 integrates Qualcomm QCA6391 (supports Wi-Fi 6 / Bluetooth 5.2) and Quectel AG52R 5G module to achieve multi-network redundant transmission; the protocol converter 4 is used to bidirectionally parse the CAN bus protocol and the mobile application layer protocol, equipped with an ARM Cortex-M7 processor, and the built-in protocol library supports J1939, ISO 14229-1 (UDS) and other motorcycle protocols; the dynamic scheduling engine 5 optimizes the data transmission priority based on the reinforcement learning algorithm (such as the navigation instruction priority is set to 0.9, and the music control is 0.3); the display controller uses OpenGL ES 3.0 to realize dynamic split-screen of the instrument interface (navigation map on the main screen, vehicle status on the secondary screen, and notification bar on the top).

[0053] It can be understood that Example 1, urban cycling navigation scenario: after the user sets the destination through the mobile phone APP, the main screen of the instrument displays a three-dimensional navigation map, and the turn prompt is automatically enlarged 500 meters before the intersection. When the vehicle speed exceeds 30km / h, the social media icons on the secondary screen are automatically hidden, and the music control interface is reduced to the bottom status bar; Example 2, vehicle fault emergency handling: when the motorcycle water temperature sensor detects that the temperature exceeds 120℃, the instrument immediately flashes a warning sign on the full screen, and sends a push notification containing a fault code (such as P0217) and a recommended solution to the mobile phone. The mobile phone APP simultaneously starts navigation to the nearest maintenance point route planning.

[0054] It can be understood that the present invention has a reasonable design and unique structure. Through multi-mode communication protocol adaptation, two-way data synchronization, dynamic priority scheduling and security control mechanism, it can achieve deep collaborative operation between the two, expand the intelligent functions of motorcycle instruments and improve driving safety, realize efficient collaboration between motorcycle instruments and smart phones, and improve driving safety and user experience.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
