Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a control method and related device for improving vehicle steering safety. Background Technology

[0002] Electronic exterior rearview mirrors are gradually replacing traditional optical rearview mirrors and becoming standard equipment in mass-produced vehicles. Existing electronic exterior rearview mirror technology mainly adopts a wired transmission solution: the physical connection between the exterior camera and the in-vehicle controller and display screen is achieved through vehicle coaxial cable and Ethernet harness. The power supply, video transmission and control commands of the camera are all completed through the harness.

[0003] Therefore, wired transmission solutions suffer from high wiring complexity and high failure rates. External cameras require high-speed video cables, power cables, and control cables that run through the doors and body panels, necessitating waterproof, vibration-resistant, and electromagnetic shielding designs. The installation process is complex and maintenance costs are high. Frequent opening and closing of doors causes the wiring harness to bend and age over time, requiring the disassembly of the door trim panels during repairs, resulting in high repair costs. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a control method and related apparatus for improving vehicle steering safety, which can solve at least one of the above-mentioned technical problems.

[0005] According to one aspect of the embodiments of this application, a control method for improving vehicle steering safety is proposed, applied to a vehicle control system. The vehicle control system includes an electronic exterior rearview mirror, a strobe basic access unit for wireless communication, and a strobe low-power access unit for wireless communication. The electronic exterior rearview mirror includes a left rearview mirror display unit and a right rearview mirror display unit. The method includes: Receive video stream data from the side and rear of the vehicle transmitted by the Star Flash basic access unit, the video stream data including video stream data from the left rear of the vehicle and video stream data from the right rear of the vehicle. The left rearview mirror display unit displays the left rear video stream data, and the right rearview mirror display unit displays the right rear video stream data. If a left turn signal trigger signal is received from the Star Flash Low Power Access Unit, the system determines whether there is an obstacle target behind the left side of the vehicle based on the left rear video stream data. If the obstacle target exists behind the left side of the vehicle, the obstacle target is marked in the video stream data behind the left side displayed on the left rearview mirror display unit; If a right turn signal trigger signal is received from the Star Flash Low Power Access Unit, the system determines whether there is an obstacle target behind the right side of the vehicle based on the right rear video stream data. If the obstacle is located to the right rear of the vehicle, the obstacle is marked in the right rear video stream data displayed on the right rearview mirror display unit.

[0006] In the above scheme, the vehicle control system further includes a camera device located at the side and rear of the vehicle. The left rear video stream data and the right rear video stream data are obtained through the following steps: The camera device acquires a first initial video stream data from the left rear of the vehicle and a second initial video stream data from the right rear of the vehicle. The first initial video stream data is preprocessed by the ISP image processing unit located locally in the vehicle to obtain the left rear video stream data; The second initial video stream data is preprocessed by the ISP image processing unit to obtain the right rear video stream data. The preprocessing includes distortion correction, HDR processing, rain and fog removal, strong light suppression, and noise reduction.

[0007] In the above scheme, the operating frequency band of the StarSpark basic access unit is 5GHz / 6GHz, and the operating frequency band of the StarSpark low-power access unit is 2.4GHz.

[0008] In the above scheme, the method further includes: Determine the ambient light level in front of the vehicle; If the ambient brightness is lower than a preset brightness threshold, the starlight low-power access unit sends an exposure parameter adjustment command to the vehicle so that the vehicle can adjust the exposure parameters of the camera device according to the exposure parameter adjustment command.

[0009] In the above scheme, the method further includes: If a reversing command is received for the vehicle, an angle adjustment command is sent to the vehicle through the StarFlash low-power access unit, so that the shooting angle of the camera device is adjusted to a preset angle according to the angle adjustment command.

[0010] In the above scheme, the method further includes: If a power-down and vehicle-locking command is received, a rearview mirror folding command is sent to the vehicle through the StarFlash low-power access unit to fold the vehicle's rearview mirrors according to the command.

[0011] In the above scheme, after receiving the power-off and vehicle-locking command for the vehicle, the method further includes: The communication link of the StarSpark basic access unit is shut down so that the StarSpark basic access unit cannot transmit the video stream data; The StarSignal Low-Power Access Unit is controlled to enter a low-power monitoring mode, so that the StarSignal Low-Power Access Unit can receive remote unlocking commands for the vehicle in the low-power monitoring mode.

[0012] According to one aspect of the embodiments of this application, a control device for improving vehicle steering safety is proposed, applied to a vehicle control system. The vehicle control system includes an electronic exterior rearview mirror, a strobe basic access unit for wireless communication, and a strobe low-power access unit for wireless communication.

The device includes: The receiving unit is used to receive video stream data of the vehicle's side and rear, transmitted by the Star Flash basic access unit. The video stream data includes video stream data of the vehicle's left rear side and video stream data of the vehicle's right rear side. The display unit is used to display the left rear video stream data in the left rearview mirror display unit and the right rear video stream data in the right rearview mirror display unit; The first judgment unit is used to determine whether there is an obstacle target on the left rear of the vehicle based on the left rear video stream data if it receives a left turn signal triggering signal transmitted by the Star Flash Low Power Access Unit. The first marking unit is used to mark the obstacle target in the left rear video stream data displayed by the left rearview mirror display unit if the obstacle target exists in the left rear of the vehicle. The second judgment unit is used to determine whether there is an obstacle target on the right rear of the vehicle based on the right rear video stream data if it receives a right turn signal triggering signal transmitted by the Star Flash Low Power Access Unit. The second marking unit is used to mark the obstacle target in the right rear video stream data displayed by the right rearview mirror display unit if the obstacle target exists behind the right side of the vehicle. According to one aspect of the present application, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the control method for improving vehicle steering safety as described above.

[0013] According to one aspect of the embodiments of this application, a computer program product is provided, the computer program product including a computer program that is read and executed by a processor of an electronic device, causing the electronic device to perform the control method for improving vehicle steering safety as described above.

[0014] The beneficial effects of this application are as follows: This application replaces the traditional wired transmission scheme with a wireless communication star-flash basic access unit and a star-flash low-power access unit, which solves the problems of complex wiring, high wire harness failure rate, high installation and maintenance cost, and poor system flexibility of the wired scheme.

[0015] Furthermore, this application utilizes the high-speed transmission characteristics of the StarSignal basic access unit to transmit and display video stream data (including left rear video stream data and right rear video stream data) in real time, and utilizes the low-power characteristics of the StarSignal low-power access unit to receive and send commands. This enables the marking of obstacle targets in the vehicle's blind spot when the vehicle is turning, and displays them in the electronic rearview mirror in real time, thereby improving the vehicle's safety when turning.

[0019] It is worth noting that in the specific embodiments of this application, video stream data, images, trigger signals, and other related data are involved. When the above embodiments of this application are applied to specific products or technologies, permission or consent from the target object is required, and the collection, use, and processing of related data must comply with relevant laws, regulations, and standards.

After obtaining the separate permission or consent from the target object, the video stream data, images, trigger signals, and other related data used to enable the embodiment of this application to operate normally can then be obtained.

[0020] Please see Figure 1 , Figure 1 This is a system architecture diagram of the control method for improving vehicle steering safety provided in this application embodiment. It includes a terminal 140, an Internet connection 130, a gateway 120, a server 110, etc.

[0021] Terminal 140 can take various forms, including desktop computers, laptops, PDAs (personal digital assistants), mobile phones, vehicle terminals, and dedicated terminals.

[0024] The following provides a detailed description of the specific implementation methods of the embodiments of this application: Please see Figure 2 , Figure 2 This is a flowchart illustrating a control method for improving vehicle steering safety provided in an embodiment of this application. The control method for improving vehicle steering safety can be implemented by server 110 and / or terminal 140. Figure 2 The control methods shown to improve vehicle steering safety include: Step 210: Receive video stream data from the side and rear of the vehicle transmitted by the Star Flash basic access unit. The video stream data includes video stream data from the left rear of the vehicle and video stream data from the right rear of the vehicle. Step 220: Display the left rear video stream data on the left rearview mirror display unit, and display the right rear video stream data on the right rearview mirror display unit; Step 230: If a left turn signal trigger signal is received from the Star Flash Low Power Access Unit, determine whether there is an obstacle target on the left rear of the vehicle based on the left rear video stream data.

Step 260: If the obstacle target exists behind the right side of the vehicle, mark the obstacle target in the right rearview mirror display unit's right rearview video stream data.

[0025] This application is based on star-flash communication technology, such as Figure 3As shown, the overall architecture of the vehicle control system of this application includes an external acquisition terminal cluster (including a camera device), a StarScan dual-mode communication core module (including a StarScan basic access unit for wireless communication and a StarScan low-power access unit for wireless communication), an in-vehicle central control unit (the method execution subject of this application), a functional safety monitoring unit, and an in-vehicle display and interaction unit (including an instrument panel and a central control screen).

[0026] I. Vehicle-mounted data acquisition terminal cluster 1. Data acquisition terminal composition: includes camera devices, including driver-side main view camera, passenger-side main view camera, blind spot camera, and forward view camera. Each camera terminal has a CMOS image sensor, ISP image processing unit, and StarFlash SLB / SLE dual-mode slave node module.

[0027] 2. Peripheral terminal components: including external loads such as turn signals, ground lights, adjustment motors, and temperature sensors integrated on the rearview mirror base, all of which are integrated with the StarSignal SLE slave node module.

[0028] 3. Working Mechanism: ① The camera captures images of the vehicle's side and rear, forming first and second initial video stream data. These are pre-processed by the local ISP unit, including distortion correction, HDR processing, rain / fog removal, strong light suppression, and noise reduction. The pre-processed high-definition video stream (video stream data) is then encoded by the SparkLink Basic Submodule (SLB) and transmitted to the vehicle's central control unit via the wireless link of the SLB. Local pre-processing reduces transmission bandwidth requirements and the computational load on the vehicle's controller, further compressing end-to-end transmission latency. SLB stands for SparkLink Basic, and SLE stands for SparkLink Low Energy, also known as SparkLink low-power access technology.

[0029] HDR processing specifically involves: Step 1: Load the images. Load the exposure sequence (e.g., several photos with exposure times of 15s, 2.5s, and 0.25s) and the corresponding exposure time data.

[0030] Step 2: Merge to generate HDR. Combine multiple images into a single 32-bit floating-point HDR image containing complete brightness information.

[0031] Step 3: Tone Mapping. Because HDR images cannot be displayed directly on a normal screen, a tone mapping algorithm is needed to compress them back to an image that can be displayed on a normal screen, while preserving as much richness in brightness and darkness as possible.

[0032] ② The peripheral terminal receives control commands (such as turn signal triggering, rearview mirror folding, etc.) issued from the vehicle through the communication link of Star Flash SLE (Star Flash Low Power Access Unit), and completes actions such as turn signal switching and rearview mirror folding. At the same time, it reports the vehicle's equipment working status, fault information, and sensor data in real time, simplifying the hardware structure of the exterior rearview mirror base.

[0033] II. Star Flash Dual-Mode Communication Core Module The system adopts a dual-mode fusion architecture of StarShan SLB+SLE, which is divided into an in-vehicle master node and an external slave node. The master node is deployed in the central control unit inside the vehicle, and the slave nodes are deployed in each external acquisition terminal and peripheral terminal. The master node establishes an encrypted wireless communication link with all slave nodes.

[0034] 1. SLB Mode (Working Mode of StarSpark Basic Access Unit): Operating in the 5GHz / 6GHz frequency band, it is used for real-time transmission of high-definition video streams; it adopts the TDMA time division multiple access scheduling mechanism to allocate a dedicated transmission time slot for each video stream, avoids transmission conflicts between multiple devices, and ensures deterministic latency; it uses Polar code channel coding and combines it with automatic retransmission requests to design a deterministic retransmission window.

[0035] 2. SLE Mode (Operating Mode of StarSpark Low-Power Access Unit): Operating in the 2.4GHz frequency band, it is optimized for low-power control scenarios, with a command response latency of ≤1ms. It is used for low-speed transmission of peripheral control commands, sensor data, device status, and fault messages, with low standby power consumption, balancing real-time and low-power requirements.

[0036] 3. Anti-interference and synchronization mechanism design: ① Anti-interference mechanism: Utilizes StarFlash native adaptive frequency hopping technology to scan the interference situation of the entire frequency band in real time, automatically switch to the interference-free channel, and automatically enable multi-link redundant transmission in strong interference environment, with dual frequency bands and dual links serving as backups for each other.

[0037] ② Synchronization mechanism: The master node periodically broadcasts a synchronization reference signal to all slave nodes to achieve clock synchronization, ensuring the timing alignment of images from multiple cameras and solving the problems of misaligned image stitching and delayed intelligent warning.

[0038] III. In-vehicle central control unit This unit is deployed inside the vehicle's dashboard and connects to the cockpit domain controller and intelligent driving domain controller via Ethernet. It includes the StarFlash master node module, video decoding unit, vision processing unit, domain controller interaction interface, and security module.

[0039] 1. Workflow: The StarShock master node receives the encoded video stream sent by the external terminal and sends it to the video decoding unit for hardware decoding. The decoded original video stream is transmitted in two paths: one path is sent directly to the in-vehicle display unit for real-time display to ensure image latency; the other path is sent to the vision processing unit for blind spot target detection, lane line recognition, obstacle warning, lane change assist, and other processing.

[0040] 2. Vehicle Domain Collaborative Design: Through in-vehicle Ethernet, bidirectional data interaction is conducted with the intelligent driving domain controller and the cockpit domain controller. The image data and processing results of the CMS are shared with the domain controller in real time, while the control commands of the domain controller are received to realize multi-scenario adaptive control: such as automatically adjusting the camera exposure parameters and display angle according to the vehicle speed, triggering blind spot warning enhancement according to the turn signal, automatically switching to the ground illumination angle according to the reversing signal, and automatically adjusting the display brightness according to the ambient light data.

[0041] IV. Functional Safety Monitoring Unit Information security protection design: The system adopts the native national cryptographic SM4 algorithm to encrypt video streams and control commands end-to-end. At the same time, it integrates a hardware root of trust to realize device identity authentication and data integrity verification, prevent wireless signals from being hijacked, tampered with, or eavesdropped on, resist malicious network attacks, and meet the requirements for vehicle information security compliance.

[0042] In some embodiments, the method further includes: Determine the ambient light level in front of the vehicle; If the ambient brightness is lower than a preset brightness threshold, the starlight low-power access unit sends an exposure parameter adjustment command to the vehicle so that the vehicle can adjust the exposure parameters of the camera device according to the exposure parameter adjustment command.

[0043] Specifically, ambient brightness can be acquired by the vehicle's ambient light sensor, measured in candela per square meter. A preset brightness threshold is, for example, 200 candela per square meter. If the ambient brightness is lower than this value, an exposure parameter adjustment command can be sent to the vehicle via the StarFlash low-power access unit. This allows the vehicle to adjust the exposure parameters of the camera device according to the command, resulting in clearer video stream data. When the vehicle enters tunnels or operates at night, the camera's local ISP automatically adjusts the exposure parameters, while the central control unit sends a brightness adjustment command via the StarFlash SLE link.

[0044] In some embodiments, the method further includes: If a reversing command is received for the vehicle, an angle adjustment command is sent to the vehicle through the StarFlash low-power access unit, so that the shooting angle of the camera device is adjusted to a preset angle according to the angle adjustment command.

[0045] When the vehicle is reversing, the central control unit receives the reversing signal from the cockpit domain controller and sends an angle adjustment command through the StarFlash SLE link to adjust the shooting angle of the cameras on both sides, automatically switch to the ground-viewing angle, and display the relative position of the vehicle body and the ground on the display screen to assist in reversing into the parking space.

[0046] In some embodiments, the method further includes: If a power-down and vehicle-locking command is received, a rearview mirror folding command is sent to the vehicle through the StarFlash low-power access unit to fold the vehicle's rearview mirrors according to the command.

[0047] Specifically, after the vehicle is powered off and locked, the central control unit sends a rearview mirror folding command through the StarSignal SLE link, and the rearview mirrors fold automatically.

[0048] In some embodiments, after receiving a power-off and vehicle-locking command for the vehicle, the method further includes: The communication link of the StarSpark basic access unit is shut down so that the StarSpark basic access unit cannot transmit the video stream data; The StarSignal Low-Power Access Unit is controlled to enter a low-power monitoring mode, so that the StarSignal Low-Power Access Unit can receive remote unlocking commands for the vehicle in the low-power monitoring mode.

[0049] Specifically, after the vehicle is powered off and locked, the camera device enters a low-power standby mode, the system shuts down the SLB main communication link, and only retains the SLE low-power listening link to respond to remote unlocking commands.

[0050] When the driver activates the turn signal by moving the turn lever (i.e., receiving a left turn signal triggering signal transmitted by the Starlight Low-Power Access Unit or a right turn signal triggering signal transmitted by the Starlight Low-Power Access Unit), the central control unit receives the lane change signal from the intelligent driving domain controller. When a moving target (obstacle target) is detected in the blind spot (side and rear), a warning sign is superimposed on the corresponding area of ​​the left or right rearview mirror display unit, and the cockpit domain controller is simultaneously triggered to trigger a warning prompt on the instrument panel.

[0051] In summary, this application can solve the problems of complex wiring, high wire harness failure rate, high installation and maintenance costs, and poor system flexibility of wired CMS (Camera Monitor System) solutions, and realize the problem of a fully wireless CMS system. It can also solve the problems of high latency, weak anti-interference ability, low synchronization accuracy and insufficient reliability of wireless CMS solutions, and improve wireless transmission performance; as well as solve the problems of weak collaboration between CMS system and intelligent driving domain and cockpit domain and limited function expansion.
