[0063] The device of the present invention calls the vehicle computer black screen software redundant lighting program stored in the memory 1005 through the processor 1001, and also performs the following operations:

[0064] The display screen has at least two power supply controls.

[0065] Through the above scheme, this embodiment obtains all tasks of the current vehicle computer and stores the codes of all tasks in different areas of the vehicle computer memory; executes the current task and the task to be jumped in time slices, and when it is detected that the display screen of the current vehicle computer is in a black screen state, switches the current task corresponding to the black screen state and executes the code of the task to be jumped; after detecting that the current task is running normally, continues to execute the current task and displays the current task on the display screen, which can effectively avoid the problem that the MCU cannot light up the instrument due to a vehicle computer SoC failure during driving, and when a black screen failure occurs on the vehicle instrument, it ensures the normal display of the instrument, thereby improving the driving safety of the user.

[0066] Based on the above hardware structure, an embodiment of the vehicle computer black screen software redundant lighting method of the present invention is proposed.

[0067] Reference Figure 2 , Figure 2 This is a flow chart of the first embodiment of the method for redundantly lighting up a black screen of a vehicle computer using software of the present invention.

[0068] In the first embodiment, the vehicle computer black screen software redundant lighting method includes the following steps:

[0069] Step S10: Acquire all tasks of the current vehicle computer, and store the codes of all the tasks in different areas of the vehicle computer memory.

[0070] It should be noted that all tasks of the current vehicle computer are obtained, and the codes of all the tasks are stored in different areas of the vehicle computer memory.

[0071] Step S20, executing the current task and the task to be jumped in time slices. When it is detected that the display screen of the current vehicle computer is in a black screen state, switching out the current task corresponding to the black screen state, and executing the code of the task to be jumped.

[0072] It should be understood that the time slice is a pre-set time period. One round of time slices can be set to 50ms. Of course, it can also be set to other values ​​according to actual conditions, such as 10ms, 30ms, 65ms, etc. This embodiment does not limit this.

[0073] It can be understood that the current task is the task being executed by the vehicle computer of the current vehicle, and the task to be jumped to is a pre-set task for alternative jump when a problem occurs in the current task. When it is detected that the display screen of the current vehicle computer is in a black screen state, the current task corresponding to the black screen state can be switched to execute the code of the task to be jumped to.

[0074] Step S30: After detecting that the current task is running normally, continue to execute the current task and display the current task on the display screen.

[0075] It can be understood that after detecting that the current task is running normally, the current task can continue to be executed and displayed on the display screen.

[0076] Through the above scheme, this embodiment obtains all tasks of the current vehicle computer and stores the codes of all tasks in different areas of the vehicle computer memory; executes the current task and the task to be jumped in time slices, and when it is detected that the display screen of the current vehicle computer is in a black screen state, switches the current task corresponding to the black screen state and executes the code of the task to be jumped; after detecting that the current task is running normally, continues to execute the current task and displays the current task on the display screen, which can effectively avoid the problem that the MCU cannot light up the instrument due to a vehicle computer SoC failure during driving, and when a black screen failure occurs on the vehicle instrument, it ensures the normal display of the instrument, thereby improving the driving safety of the user.

[0077] Further, Figure 3 FIG. 2 is a flow chart of a second embodiment of a method for redundancy lighting a vehicle computer black screen with software according to the present invention. Figure 3 As shown, based on the first embodiment, a second embodiment of the vehicle computer black screen software redundant lighting method of the present invention is proposed. In this embodiment, the step S10 specifically includes the following steps:

[0078] Step S11, obtaining all tasks of the current vehicle computer, wherein all tasks include currently executed tasks, tasks to be jumped to, and unexecuted tasks.

[0079] It should be noted that all tasks of the current vehicle computer are tasks corresponding to all programs pre-set in the vehicle computer, and all tasks include currently executed tasks, tasks to be jumped to, and unexecuted tasks.

[0080] Step S12: establishing a RAM shared data area for the currently executed task and the task to be jumped to, and storing all the codes in different areas of the vehicle computer memory ROM.

[0081] It is understandable that by establishing a shared data area of ​​the random access memory (RAM) of the currently executed task and the task to be jumped, all the codes can be stored in different areas of the vehicle computer solid-state semiconductor memory (Read Only Memory, ROM).

[0082] This embodiment adopts the above scheme to obtain all the tasks of the current vehicle computer, and the tasks include currently executed tasks, tasks to be jumped and unexecuted tasks; establish a RAM shared data area for the currently executed tasks and the tasks to be jumped, and store all the codes in different areas of the vehicle computer memory ROM; it can store the task code in advance, effectively avoiding the problem that the MCU cannot light up the instrument due to a vehicle computer SoC failure during driving, and improving the speed and efficiency of redundant lighting of the vehicle computer black screen software.

[0083] Further, Figure 4 FIG. 1 is a flow chart of a third embodiment of a method for redundancy lighting a vehicle computer black screen with software according to the present invention. Figure 4 As shown, based on the first embodiment, a third embodiment of the vehicle computer black screen software redundant lighting method of the present invention is proposed. In this embodiment, the step S20 specifically includes the following steps:

[0084] Step S21, start executing the code entry points of the current task and the task to be jumped to, and execute the codes of the current task and the task to be jumped to in time slices.

[0085] It should be noted that after the code entry points for executing the current task and the task to be jumped to are started, the codes of the current task and the task to be jumped to may be executed in time slices.

[0086] Step S22: When it is detected that the display screen of the current vehicle computer is in a black screen state, check the code running state of the current task that causes the display screen to be black.

[0087] It is understandable that when it is detected that the display screen of the current vehicle computer is in a black screen state, the code running state of the current task causing the display screen to be black can be checked in time.

[0088] Step S23: When the code running state is faulty or abnormal, the current task is switched out and the code of the task to be jumped is executed.

[0089] It should be understood that when the code running state is faulty or abnormal, the current task can be switched out in time, so as to execute the code of the task to be jumped.

[0090] Furthermore, the step S23 specifically includes the following steps:

[0091] When the code running state is faulty or abnormal, selecting a task with a higher priority from the tasks to be jumped as a target task;

[0092] The code of the target task is executed, and the target task is displayed on the display screen.

[0093] It can be understood that when the code running state is faulty or abnormal, a task with a higher priority can be selected from the tasks to be jumped to as the target task; generally, the task with the highest priority is selected. Of course, the most suitable task can also be switched as the target task according to the current usage scenario. This embodiment does not limit this, executes the code of the target task, and displays the target task on the display screen.

[0094] Accordingly, before step S20, the vehicle computer black screen software redundant lighting method further includes the following steps:

[0095] Real-time detection or detection according to a preset detection cycle to determine whether the current task has returned to normal.

[0096] In the specific implementation, see Figure 5 , Figure 5 This is a schematic diagram of the code storage logic in the vehicle computer black screen software redundant lighting method of the present invention, such as Figure 5 As shown, the second part of the solution is as follows: A implements the complete functional logic, and B implements the necessary instrument functional logic (independent of the SoC, only receiving necessary signals such as vehicle speed, speed, gear position, ready, some fault lights, and some functional indicator lights); when A fails, it jumps to B to work, and when A completes initialization and returns to normal, it jumps from B to A first. Establish a RAM shared data area for tasks A and B.

[0097] Generally, the two codes are stored in different areas of ROM: Code A is stored in the starting address of ROM from 0x0000 to 0x1FFF;

[0098] Code B is stored in another area of ​​ROM, such as 0x2000 to 0x2FFF (for a simplified version of Code A).

[0099] Startup process: At startup, the entry points of startup code A and code B start to execute in time slices. Under normal circumstances, the instrument display only shows the A status. During the execution of code A, the running status of code A will be checked regularly; if a fault or abnormality is detected in code A, the core will switch the instrument to display the status of code B. If A is detected to be running normally or other fault handling operations are performed.

[0100] Task management: Each code instance can be considered a task; a task switching mechanism can be designed so that the core can switch between two tasks under certain circumstances (e.g., task priority changes, resource requirements, etc.); this may involve saving and restoring the task's context (e.g., register values, stack pointer, etc.).

[0101] Through the above scheme, this embodiment starts the code entry points for executing the current task and the task to be jumped, and executes the codes of the current task and the task to be jumped in time slices; when it is detected that the display screen of the current vehicle computer is in a black screen state, the code running status of the current task that causes the display screen to be black is checked; when the code running status is a fault or an abnormality, the current task is switched off and the code of the task to be jumped is executed; the current task can be quickly switched and jumped to other task codes, effectively avoiding the problem that the MCU cannot light up the instrument due to a vehicle computer SoC fault during driving, and improving the speed and efficiency of redundant lighting of the vehicle computer black screen software.

[0102] Further, Figure 6 FIG. 4 is a flow chart of a fourth embodiment of a method for redundancy lighting a vehicle computer black screen with software according to the present invention. Figure 6 As shown, based on the first embodiment, a fourth embodiment of the vehicle computer black screen software redundant lighting method of the present invention is proposed. In this embodiment, the step S30 specifically includes the following steps:

[0103] Step S31, after detecting that the current task is running normally, continue to execute the current task, display the current task on the display screen, and transfer the task to be jumped to the background for running.

[0104] It should be noted that after detecting that the current task is running normally, the current task continues to be executed, the current task is displayed on the display screen, and the task to be jumped is transferred to the background for running.

[0105] In a specific implementation, the display screen has at least two power supply controls, see Figure 7 , Figure 7 FIG. 1 is a schematic diagram of hardware control in the vehicle computer black screen software redundant lighting method of the present invention, such as Figure 7 As shown in the figure, the instrument backlight is redundantly designed and an additional power supply control is added to improve the reliability and stability of the system; reliable switching between two tasks (A and B) is achieved to ensure seamless switching to task B when task A fails, and when task A completes initialization and returns to normal, it can jump from task B to task A first, ensuring the continuous normal operation of the instrument system and realizing specific logical control of instrument functions by different tasks; an additional control is added in hardware, and the MCU selects the power source according to the fault control.

[0106] Through the above scheme, this embodiment starts the code entry points for executing the current task and the task to be jumped, and executes the codes of the current task and the task to be jumped in time slices; when it is detected that the display screen of the current vehicle computer is in a black screen state, the code running status of the current task that causes the display screen to be black is checked; when the code running status is faulty or abnormal, the current task is switched off and the code of the task to be jumped is executed. After detecting that the current task is normal, the execution of the current task can be quickly resumed, and the problem of MCU being unable to light up the instrument due to a vehicle computer SoC failure during driving of the vehicle can be effectively avoided. When a black screen failure occurs on the vehicle instrument, the normal display of the instrument is guaranteed, thereby improving the driving safety of the user.

[0107] Correspondingly, the present invention further provides a vehicle computer black screen software redundant lighting device.

[0108] Reference Figure 8 , Figure 8 This is a functional module diagram of the first embodiment of the vehicle computer black screen software redundant lighting device of the present invention.
