Description

Technical Field

[0001] The present invention relates to the technical field of vehicle instrument display, and in particular to a vehicle instrument display control system and method, and a computer-readable storage medium. Background Art

[0002] As vehicles become increasingly intelligent, the number of electronic controllers within them increases. Ensuring the functional safety of these electronic controllers from both a software and hardware perspective is becoming increasingly important. Infotainment domain controllers and displays, as the primary interface for human-machine interaction within the vehicle, primarily meet display-related requirements within the vehicle's functional safety landscape.

[0003] Currently, there are two main vehicle display solutions:

[0004] Solution 1: Independent instrument controller to implement display safety assurance mechanism;

[0005] Option 2: Use the display security mechanism built into the infotainment domain controller’s SOC chip.

[0006] In the process of implementing the present invention, the inventors found that the above solution has at least the following distinguishing technical problems:

[0007] In solution one, implementing a display security mechanism with an independent instrument controller doesn't conform to the current trend of integration and domain control in mainstream electronic and electrical architectures. According to the current mainstream electronic and electrical architecture, the infotainment domain controller is responsible for the main control of the instrument panel, central control panel, and other screens. The instrument panel only displays information and is not responsible for specific calculation logic.

[0008] In Option 2, the display security protection mechanism of the SOC chip used in the infotainment domain controller is limited by the chip selection and the capabilities of the chip itself. For example, the chip itself only supports fixed positions for functional safety icons that do not share positions with non-functional safety icons, opaque icon areas (which restrict visual design), and a limited number of supported icon areas. Summary of the Invention

[0046] The detailed description of the accompanying drawings is intended as an explanation of the presently preferred embodiments of the present invention and is not intended to represent the only form in which the present invention can be implemented. It should be understood that the same or equivalent functions can be accomplished by different embodiments that are intended to be included in the spirit and scope of the present invention.

[0047] See Figure 1 One embodiment of the present invention provides a vehicle instrument display control system, including an infotainment domain controller and an instrument display device; the infotainment domain controller includes an MCU and a SOC; the instrument display device includes a graphic comparison module and an instrument screen;

[0048] The MCU is used to obtain multiple display request signals, and determine one or more icon information to be detected and one or more icon information not to be detected that need to be displayed on the instrument screen according to the multiple display request signals; send the one or more icon information to be detected and the one or more icon information not to be detected to the SOC; and send the one or more icon information to be detected to the instrument display device; specifically, the multiple display request signals are issued by other domain controllers of the vehicle, such as the intelligent driving domain control, the body controller, etc., and the multiple display request signals are, for example, vehicle speed display request signals, rotation speed display request signals, energy consumption display request signals, fault display request signals, door not closed display request signals, turn signal display request signals, etc.; there are many types of fault display request signals, such as engine faults, sensor faults, etc.; wherein, the icon information not to be detected is a conventionally displayed icon, such as a vehicle speed display request signal, a rotation speed display request signal, an energy consumption display request signal, etc., and does not require detection and verification, and the icon information to be detected is an unconventionally displayed icon, such as a fault display request signal, etc., and needs to be arbitrated / calculated by the MCU to determine whether it needs to be displayed;

[0049] The SOC is used to render an instrument image to be displayed based on the one or more to-be-detected icon information and the one or more non-to-be-detected icon information it receives; wherein the instrument image to be displayed includes an image background, one or more to-be-detected icon information, and one or more non-to-be-detected icon information. Specifically, the SOC of this embodiment only renders the display image to be displayed on the instrument display device and is not responsible for the specific operation logic or the calculation logic of the displayed icons. Therefore, the vehicle instrument display system of this embodiment is not limited by the SOC chip selection of the infotainment domain controller and the chip's own capabilities, avoiding the disadvantage of the current infotainment domain controller's SOC chip's inherent image assurance mechanism having many limitations.

[0050] The graphic comparison module is used to obtain one or more corresponding preset sample icon information based on the one or more icon information to be detected received by it; and compare the one or more preset sample icon information with the one or more icon information to be detected in the instrument image to be displayed. Specifically, this embodiment adds a graphic comparison module to the instrument display device, such as an LVDS Splitter chip. The graphic comparison module is used to perform icon comparison verification and is not responsible for the calculation logic of the displayed icon, which is in line with the current mainstream trend of integrated and domain-controlled electronic and electrical architecture.

[0051] The instrument screen is used to display the instrument image to be displayed when the one or more preset sample icon information is consistent with one or more icon information to be detected in the instrument image to be displayed; when there is at least one sample icon information that is inconsistent with at least one icon information to be detected in the instrument image to be displayed, the at least one sample icon information is superimposed on the instrument image to be displayed and then displayed; specifically, assuming that there are 3 icon information to be detected, namely, icon 1 to be detected, icon 2 to be detected, and icon 3 to be detected, then 3 sample icon information will be obtained accordingly, namely, sample icon 1, sample icon 2, and sample icon 3, and the graphic comparison module will compare the sample icon information. The three icons to be detected are compared one by one with the three sample icons. If icon 1 to be detected is consistent with sample icon 1, icon 2 to be detected is consistent with sample icon 2, and icon 3 to be detected is consistent with sample icon 3, then the instrument screen directly displays the instrument image to be displayed; if icon 1 to be detected is inconsistent with sample icon 1, or icon 2 to be detected is inconsistent with sample icon 2, or icon 3 to be detected is inconsistent with sample icon 3, then the inconsistent sample icon 1, or sample icon 2, or sample icon 3 is superimposed on the instrument image to be displayed and then displayed. This can meet the functional safety requirements for the instrument icon display of the entire vehicle decomposed into the infotainment domain under the domain control architecture, and ensure that the instrument icons are displayed correctly. Figure 2 This is a schematic diagram of the calibration of the instrument image to be displayed in this embodiment, which can be referred to Figure 2 Understand the above.

[0052] In some embodiments, the MCU is specifically used to obtain multiple icon information requested for display based on the multiple display request signals, and determine whether to display and detect the multiple icon information requested for display based on a preset icon display strategy, to obtain one or more icon information to be detected and one or more icon information not to be detected that need to be displayed on the instrument screen.

[0053] Specifically, in this embodiment, the multiple icon information requested for display needs to be arbitrated / calculated by the MCU to determine whether they need to be displayed; for example, the infotainment domain controller receives a fault signal, but needs to judge and calculate the current environment of the entire vehicle (such as voltage, power, etc.) to decide whether to display the fault icon on the instrument screen; for another example, the infotainment domain controller receives two display request signals and both need to light up the corresponding fault icon at the same position, but these two fault icons have a priority relationship, then the MCU arbitrates which one to display on the actual instrument according to the priority of the two fault icons, the one with higher priority is displayed, and the one with lower priority is not displayed; it should be noted that the above examples are only for illustration, and the preset icon display strategy is not limited to the above examples, and can be specifically set according to the specific technical scenario. The main purpose of the embodiment of the present invention is that the infotainment domain controller MCU is the main control to determine the display elements, and the MCU on the instrument display device side does not need to participate in the decision-making.

[0054] In some embodiments, the infotainment domain controller includes a first CAN transceiver, which is used to obtain the multiple display request signals from the CAN / CANFD bus and send the multiple display request signals to the MCU.

[0055] In some embodiments, the MCU is used to convert the one or more icon information to be detected into a CAN / CANFD signal and send it to the first CAN transceiver;

[0056] The first CAN transceiver is further used to send the CAN / CANFD signal to the CAN / CANFD bus;

[0057] The instrument display device includes a second CAN transceiver, the second CAN transceiver is used to obtain the CAN / CANFD signal from the CAN / CANFD bus, and obtain the one or more icon information to be detected according to the CAN / CANFD signal;

[0058] Specifically, in this embodiment, the verification signal is transmitted between the infotainment domain controller and the instrument display device via the CAN / CANFD bus, bypassing the complex SOC chip, so that the entire solution can simplify the analysis process when conducting functional safety-related certification.

[0059] In some embodiments, the infotainment domain controller further includes a serializer, and the instrument display device is provided with a deserializer;

[0060] The MCU is used to send the one or more icon information to be detected to the serializer through the SPI interface, and the serializer is used to send the one or more icon information to be detected received to the deserializer through the GMSL interface;

[0061] The deserializer is configured to send the received one or more to-be-detected icon information to the graphic comparison module.

[0062] Specifically, in this embodiment, the icon information to be detected that is calculated / arbitrated by the MCU of the infotainment domain controller and is ultimately to be displayed on the instrument screen can be transmitted through the above-mentioned SPI interface. In this way, for an instrument display device without other CAN / CANFD signal interactions, a CAN transceiver can be saved, thereby saving hardware costs.

[0063] In some embodiments, the instrument display device further includes a storage module, which may be a built-in flash memory of the instrument display device, and the storage module is used to store a plurality of preset sample icon information;

[0064] The graphic comparison module is specifically configured to obtain, from the storage module, one or more preset sample icon information that matches the one or more icon information to be detected based on the one or more icon information to be detected.
