Description

Technical Field

[0001] This application relates to the field of vehicle information display technology, and in particular to a vehicle information display method, system chip, electronic device, storage medium and program product. Background Technology

[0002] With the continuous evolution of automotive electronic and electrical architecture, traditional mechanical in-vehicle instruments, due to their limited display information and inability to interact with in-vehicle driver assistance systems, can no longer meet the market and user demands for high-end, intelligent, and personalized human-machine interaction experiences in in-vehicle displays. Therefore, mechanical in-vehicle instruments are gradually being replaced by electronic in-vehicle instruments.

[0003] The vehicle's electronic instrument panel is responsible for the information interaction between the driver and the vehicle system, and needs to display the following key information in real time: 1. Vehicle status information, such as vehicle speed, engine speed, fuel level, battery level, and other powertrain parameters; 2. Driving safety information: such as seat belt status, door closure status, tire pressure monitoring and other real-time safety parameters; 3. Fault warning information: such as requests for assisted driving takeover, alarms for abnormal critical components, and other important safety prompts.

[0004] In automotive electronic instrument clusters, a common technical solution is to use the GPU (Graphics Processing Unit) in the SoC (System on Chip) to complete the graphics rendering and display control tasks. This allows human-computer interaction content such as vehicle status information, safety indication information, and fault warning information to be presented in 3D graphics on the electronic instrument cluster or central control display screen, thereby improving user experience and interaction efficiency.

[0005] However, in electronic instrument systems that use GPUs for 3D graphics rendering, the GPU module itself has extremely high hardware complexity (the number of transistors in a GPU is far greater than the number of transistors in other modules within the chip), so its probability of random hardware failure is also high. This will significantly increase the probability of display failure in electronic instruments and cause safety issues.

[0006] Therefore, ensuring high system reliability and functional safety while guaranteeing high-performance graphics display capabilities has become one of the key technical issues that urgently need to be addressed. Summary of the Invention

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0027] It should also be noted that, in this document, the terms "comprising" or "including" include not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] like Figure 1 As shown, embodiments of this application provide a vehicle information display method applied to a system-on-a-chip (SoC). The SoC includes a CPU, a GPU, and a memory unit interconnected via a system bus. The SoC can be a system-on-a-chip (SoC) or similar device-on-a-chip (SoC). The following embodiments of this application use an SoC as an example for illustration. The vehicle information display method provided by this application includes: S10. The CPU transmits vehicle information acquired from the outside to the memory unit via the system bus, allowing the GPU to read the vehicle information, perform 3D rendering processing, and output the display. The vehicle information includes, but is not limited to, at least one of the following: vehicle speed, engine speed, fuel level, battery level, driving range, navigation information (e.g., lane keeping assist signs, lane change assist signs, lane view, global navigation path, etc.), ADAS takeover warnings, and fault warnings. The terminal used for information display includes, but is not limited to, any one of the following: electronic instruments (including LCD instruments and OLED instruments), HUD head-up display devices, and central control displays.

[0029] Taking a System-on-a-Chip (SoC) chip as an example, it obtains vehicle information through the car's CAN bus or other vehicle information measurement modules (e.g., inertial measurement units). The CPU then obtains this vehicle information via the SoC system bus. Based on the graphics interaction requirements and the vehicle information, the CPU generates a graphics task and transmits it to the memory unit via the SoC system bus. The GPU then reads the graphics task, performs 3D rendering processing, and outputs the result for display. The graphics task includes graphics interaction requirements and vehicle information; different vehicle information has different graphics interaction requirements (for example, requirements for 3D display effects specific to the vehicle information). Under normal circumstances, the GPU obtains the graphics task from the memory unit via the SoC system bus, performs 3D rendering processing on the vehicle information within it to obtain 3D display information, and then outputs the result for display.

[0030] S20. When the GPU malfunctions, the CPU generates two-dimensional display information based on the vehicle information and outputs it for display.

[0031] For example, when the GPU fails, the CPU takes over the task of processing and displaying vehicle information. For instance, when the GPU fails, the CPU retrieves the graphics task from memory, processes the vehicle information therein to obtain two-dimensional display information, and then outputs it for display; or, when the GPU fails, the CPU directly retrieves vehicle information from an external source via the SOC system bus, processes it to obtain two-dimensional display information, and then outputs it for display. The terminal used for information display includes, but is not limited to, any one of the following: electronic instruments (including LCD instruments, OLED instruments), HUD head-up displays, and central control displays.

[0032] In this embodiment, when the GPU malfunctions, the CPU takes over the display processing of vehicle information. It employs a dimensionality-reduced, simplified drawing method to perform two-dimensional display processing and output of the vehicle information (e.g., the CPU only needs to generate simplified two-dimensional graphics). This completes the output display function of vehicle information, avoiding driver misjudgment and operational risks caused by display interruptions, and significantly improving the system's functional safety and fault tolerance. Furthermore, it avoids the negative impact of excessive CPU resource consumption caused by 3D rendering of vehicle information (e.g., affecting normal CPU operation). In other words, it achieves a lightweight display with extremely low CPU resource consumption without fully implementing the GPU's high-complexity rendering effects.

[0033] In some embodiments, when the GPU malfunctions, the CPU generates and outputs two-dimensional display information based on at least the vehicle information, including: the CPU generates and outputs two-dimensional display information based on at least key information in the vehicle information. The key information is related to vehicle driving safety and can be preset information or information automatically filtered based on the vehicle status. For example, when the vehicle information includes vehicle speed, engine speed, fuel level, battery level, driving range, and navigation information, the preset key information is vehicle speed, driving range, and navigation information. Alternatively, when fuel level, battery level, and driving range are sufficient, fuel level, battery level, and driving range can be determined as non-key information, while vehicle speed, engine speed, and navigation information can be determined as key information. Therefore, the CPU generates and outputs two-dimensional display information only for the key information.

[0034] In this embodiment, the CPU only generates and outputs two-dimensional display information for key information. This not only ensures the real-time display of key information required for safe driving, but also avoids excessive CPU resource consumption and does not affect the normal function of the system.

[0035] In some embodiments, the two-dimensional display information includes: two-dimensional graphics and / or text information and / or preset two-dimensional image elements, etc. Exemplarily, the spatial layout of the two-dimensional element information contained in the two-dimensional display information corresponds to the spatial layout of the three-dimensional element information contained in the three-dimensional display information. For example, the spatial layout of the two-dimensional element information contained in the two-dimensional display information can be obtained by projecting the three-dimensional element information contained in the three-dimensional display information onto a two-dimensional plane.

[0036] In this embodiment, by setting the spatial layout of the two-dimensional element information contained in the two-dimensional display information to correspond to the spatial layout of the three-dimensional element information contained in the three-dimensional display information, even when the GPU fails and the CPU takes over processing, the final style of the two-dimensional display interface remains close to the original three-dimensional UI design when the GPU is functioning correctly. This minimizes the impact on user observation when switching from three-dimensional to two-dimensional display (and then back to three-dimensional display after the GPU recovers), allowing users to quickly adapt to the display changes and rapidly and accurately locate the key information they need to observe on the display interface. This also improves driving safety to some extent.

[0037] In some embodiments, the vehicle information display method further includes: pre-generating preset two-dimensional image elements and storing them in the memory unit; when the GPU fails, the CPU generates two-dimensional display information based on the vehicle information and outputs the display, including: the CPU obtains the vehicle information and the preset two-dimensional image elements from the memory unit and generates two-dimensional display information.

[0038] For example, preset two-dimensional image elements are pre-generated for different vehicle information and stored in memory units. The preset two-dimensional image elements are relatively fixed elements required for the two-dimensional display of the corresponding vehicle information (e.g., text icons representing speed, fuel and battery level icons, driving information icons, warning icons, etc.).

[0039] For example, for vehicle speed, the corresponding preset two-dimensional image element is a two-dimensional speedometer. The CPU only needs to generate the corresponding speed pointer in real time based on the vehicle speed information, and then combine it with the two-dimensional speedometer to generate complete two-dimensional display information of the vehicle speed.

[0040] For example, for engine speed, the corresponding preset two-dimensional image element is a two-dimensional engine tachometer. The CPU only needs to generate the corresponding speed pointer in real time based on the engine speed information, and then combine it with the two-dimensional engine tachometer to generate complete two-dimensional display information of the speed.

[0041] In some embodiments, preset two-dimensional image elements can be stored in FLASH memory and loaded into memory when the device is powered on. Because the data size of the two-dimensional image elements is small, the time required for CPU access in the event of a GPU failure is extremely short, thus meeting the real-time requirements of fault response.

[0042] The vehicle information display method in this embodiment pre-generates preset two-dimensional image elements for the fixed and unchanging parts of different vehicle information when displaying it in two dimensions. Therefore, when the CPU processes the vehicle information, it only needs to generate corresponding two-dimensional images or information for the dynamically changing parts, and combine these with the corresponding preset two-dimensional image elements to generate complete two-dimensional display information. This further reduces the amount of data that the CPU needs to process, alleviates the CPU's burden, improves the generation efficiency of two-dimensional display information, and ensures the real-time nature of the output two-dimensional display information.

[0043] The CPU takeover strategy adopted by the vehicle information display method in the above embodiments has a very low impact on system response speed and resource consumption. While ensuring that functional safety requirements are met, it will not interfere with the normal operation of other modules in the system, and has good real-time performance, compatibility and engineering practicality.

[0044] In some embodiments, the vehicle information display method further includes: setting access permissions for the preset two-dimensional image elements in the memory unit, wherein the access permissions are only allowed to be accessed by the CPU. For example, the preset two-dimensional image elements stored in the memory unit are set to be accessible only by threads originating from the CPU; no other thread or host can access these preset two-dimensional image elements.

[0045] The vehicle information display method in this embodiment implements thread protection for CPU takeover tasks and adopts a memory protection mechanism for pre-stored preset two-dimensional image elements and other drawing information. This can effectively prevent unauthorized access from tampering with the preset two-dimensional image elements and ensure the correctness and reliability of information access after the CPU takes over the processing and display of vehicle information.

[0046] like Figure 2 The diagram shows a flowchart of another embodiment of the vehicle information display method of this application. In this embodiment, the vehicle information display method further includes: S30. When the GPU malfunctions, the CPU is detected in real time to see if it has generated and output two-dimensional display information.

[0047] For example, when a GPU failure is detected, timing begins, and the CPU is monitored in real time to see if it has completed the generation and output of two-dimensional display information.

[0048] S40. If the CPU does not generate and output two-dimensional display information within a preset time, a black screen display command is output.

[0049] In this embodiment, the vehicle information display method employs a timeout detection mechanism after the CPU takes over the processing and display of vehicle information. Specifically, a timer begins when a GPU failure occurs. The timer ends when the CPU successfully outputs two-dimensional display information without a timeout. If the timer exceeds the fault tolerance time (e.g., a set 100ms) and the CPU still fails to successfully output two-dimensional display information, the system further downgrades to a black screen display to alert the driver to the malfunction, facilitating safe driving or parking and preventing potential dangers.

[0050] In some embodiments, the vehicle information display method further includes: setting access permissions for the preset two-dimensional image elements in the memory unit, wherein the access permissions are only allowed to be accessed by the CPU; when the GPU fails, detecting in real time whether the CPU has generated and output two-dimensional display information; if the CPU is not detected to generate and output two-dimensional display information within a preset time, outputting a black screen display command.

[0051] In this embodiment, the vehicle information display method, under CPU takeover mode, employs a memory protection mechanism and a timeout detection mechanism to ensure the correctness of CPU takeover and meets the fault latency detection requirements in functional safety standards.

[0052] In some embodiments, the SOC chip further includes a safety detection module for detecting whether the GPU has malfunctioned; the method further includes: when the safety detection module detects that the GPU has malfunctioned, it notifies the CPU to take over the processing and output of the vehicle information. The safety detection module can be implemented as FuSa IP (Functional Safety Intellectual Property), integrated into the SOC chip.

[0053] The GPU failures in this application include not only the GPU core, but also all related functional modules involved in the graphics processing flow. For example, the failure determination objects include, but are not limited to: the GPU main processing unit, system communication interfaces (including chip-level interconnect modules such as AHB, AXI, and APB), etc.

[0054] For example, the security detection module can detect soft errors in the GPU cache logic, erroneous access to resource and configuration partitions, resource access address errors, processing timeout errors, redundant design of the GPU top-level partition, CRC check of GPU memory processor partitions, parity check of GPU interfaces, and access interval protection of partitions. A self-test is performed during the boot process to detect these GPU faults.

[0055] In some embodiments, the SOC chip further includes a 2D acceleration engine. In this embodiment, the vehicle information display method includes: the CPU calling the 2D acceleration engine to generate two-dimensional display information corresponding to the vehicle information. Exemplarily, the CPU sends an information processing instruction to the 2D acceleration engine, the instruction including the vehicle information. In this embodiment, for an SOC chip with a 2D acceleration engine, the CPU uses command sending rather than direct software mapping to generate the two-dimensional display information, further reducing the impact on CPU load and lowering the demand on CPU performance.

[0056] like Figure 3 The diagram shown is a flowchart of another embodiment of the vehicle information display method of this application. This embodiment includes the following steps: S100: When a GPU malfunctions, an error message is generated, and the security detection module detects this error message. S200, the security detection module generates an interrupt notification to the CPU that an error has occurred; After the S300 CPU learns of the error, it resets the GPU and, in conjunction with the externally input vehicle information, stores the preset text reminder and 2D icon data in the frame buffer in memory. In the S400, the electronic instrument display changes from 3D images to basic text information and / or 2D icons, but the electronic instrument still has real-time vehicle interaction capabilities.

[0057] like Figure 4 The diagram shown is a schematic block diagram of an embodiment of the SOC chip of this application. In this embodiment, the SOC chip acquires vehicle information input via a CAN bus and connects to a display terminal via an external circuit (e.g., a display circuit). Furthermore, in this embodiment, RAM (corresponding to the memory unit described in the preceding embodiments) is configured externally to the SOC chip. This memory unit can also be configured internally to the SOC chip; that is, the memory unit in this application can be integrated internally or externally to the SOC chip, and this application does not limit this.

[0058] Continue to refer to Figure 4The SOC chip includes an SOC system bus and a CPU, GPU, security detection module (i.e., FuSa IP), peripheral interface module, memory controller, display controller, and display interface directly or indirectly connected to the SOC system bus. The security detection module, peripheral interface module, memory controller, display controller, and display interface are all integrated circuits within the SOC chip. Furthermore, the peripheral interface module receives vehicle information at its input and transmits this information to the CPU via the SOC system bus at its output. When the security detection module detects a GPU malfunction, it sends an error notification to the CPU. The CPU then generates two-dimensional image data based on the vehicle information and transmits it to RAM (e.g., stored in the RAM's frame buffer; it can also store pre-set warning text and two-dimensional icon data). Finally, the memory controller transmits the data from the frame buffer to the display interface via the display controller, and then outputs the image data to the display terminal via an external display circuit.

[0059] In some embodiments, Figure 4 The SOC chip shown can execute the vehicle information display method of this application to achieve the following steps: Step 1. The SoC receives vehicle information via the automotive communication bus (such as the CAN bus); Step 2. The security detection module's security mechanism detects a GPU malfunction and transmits the malfunction information to FuSaIP; Step 3. FuSa IP generates an interrupt message to transmit the GPU's fault status to the CPU; Step 4. The CPU generates and outputs corresponding image data to the frame buffer area based on the vehicle information. Unlike the multi-layered, complex 3D image data originally rendered by the GPU, the image data output by the CPU is simplified 2D graphics and text information, used to continuously display key driving information even when the GPU malfunctions. Step 5. The Display Controller periodically retrieves the display data output by the CPU from the frame buffer area in RAM and transmits the display data to the display circuit outside the SoC chip through the Display Interface, ultimately displaying two-dimensional key driving information in the electronic LCD instrument panel or central control panel.

[0060] The vehicle information display method and SOC chip implementation of this application are a CPU safety takeover method and system for GPU failure in an in-vehicle display device. When FuSa IP detects a GPU failure, the CPU executes the vehicle information output display function, which helps the driver to still obtain key vehicle information and perform correct driving operations even when the GPU of the SoC fails, thereby improving the safety performance of the system.

[0061] In some embodiments, this application also provides a system-on-a-chip (SoC) comprising a CPU, a GPU, and a memory unit interconnected via a system bus; wherein, The CPU is configured to transmit vehicle information acquired from the outside to the memory unit via the system bus; The GPU is configured to read the vehicle information from the memory unit, perform 3D rendering processing, and output the display. The CPU is also configured to: when the GPU fails, the CPU generates and outputs two-dimensional display information based on the vehicle information.

[0062] In this embodiment, when the GPU malfunctions, the CPU takes over the display processing of vehicle information. It employs a dimensionality-reduced, simplified drawing method to perform two-dimensional display processing and output of the vehicle information (e.g., the CPU only needs to generate simplified two-dimensional graphics). This completes the output display function of vehicle information, avoiding driver misjudgment and operational risks caused by display interruptions, and significantly improving the system's functional safety and fault tolerance. Furthermore, it avoids the negative impact of excessive CPU resource consumption caused by 3D rendering of vehicle information (e.g., affecting normal CPU operation). In other words, it achieves a lightweight display with extremely low CPU resource consumption without fully implementing the GPU's high-complexity rendering effects.

[0063] In some embodiments, the memory unit stores pre-generated preset two-dimensional image elements; when the GPU malfunctions, the CPU generates and outputs two-dimensional display information based on the vehicle information, including: the CPU obtains the vehicle information and the preset two-dimensional image elements from the memory unit and generates two-dimensional display information.

[0064] In some embodiments, the preset two-dimensional image elements in the memory unit are provided with access permissions, which are only allowed to be accessed by the CPU.

[0065] In some embodiments, the SOC chip further includes a security detection module for detecting whether the GPU has malfunctioned; when the security detection module detects that the GPU has malfunctioned, it notifies the CPU to take over the processing and output of the vehicle information.

[0066] In some embodiments, the security detection module is further configured to: when the GPU malfunctions, detect in real time whether the CPU generates and outputs two-dimensional display information; if the CPU does not generate and output two-dimensional display information within a preset time, output a black screen display command.

[0067] In some embodiments, the two-dimensional display information includes: two-dimensional graphics and / or text information and / or preset two-dimensional image elements.
