[0053] 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;

[0054] When detecting that the display screen of the current vehicle computer is in a black screen state, checking the code running state of the current task causing the display screen to be black;

[0055] When the code running state is faulty or abnormal, the current task is switched and the code of the task to be jumped is executed.

[0056] 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 further performs the following operations:

[0060] Real-time detection or detection according to a preset detection period to determine whether the current task has returned to normal.

[0062] 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.

[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 further performs the following operations:

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

[0065] The embodiment obtains all tasks of a current car machine, stores codes of the all tasks in different areas of a car machine memory, executes current tasks and to-be-jumped tasks in time slices, switches off the current tasks corresponding to a black screen state of the current car machine when detecting that the display screen of the current car machine is in the black screen state, executes codes of the to-be-jumped tasks, continues to execute the current tasks after detecting that the current tasks are normally running, and displays the current tasks on the display screen. The problem that an MCU cannot light up an instrument due to a car machine SoC fault during vehicle driving is effectively avoided, the instrument is normally displayed when the vehicle instrument appears a black screen fault, and the safety of user driving is improved.

[0066] Based on the above hardware structure, the car machine black screen software redundancy lighting method embodiment of the present application is proposed.

[0067] Reference Figure 2 , Figure 2 The flowchart of the first embodiment of the car machine black screen software redundancy lighting method of the present application is shown.

[0068] In the first embodiment, the car machine black screen software redundancy lighting method includes the following steps:

[0069] Step S10, all tasks of a current car machine are obtained, and codes of the all tasks are stored in different areas of a car machine memory.

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

[0071] Step S20, current tasks and to-be-jumped tasks are executed in time slices, the current tasks corresponding to a black screen state of the current car machine are switched off when detecting that the display screen of the current car machine is in the black screen state, and codes of the to-be-jumped tasks are executed.

[0072] It should be understood that a time slice is a pre-set time period, and one round of time slice can be set to 50 ms, of course, it can also be set to other values according to actual conditions, for example, 10 ms, 30 ms, 65 ms, etc., and the embodiment does not limit this.

[0073] It can be understood that the current task is a task that is being executed by the car machine of the current vehicle, and the to-be-jumped task is a pre-set task for backup jumping after the current task has a problem. When detecting that the display screen of the current car machine is in a black screen state, the current task corresponding to the black screen state can be switched off, and the code of the to-be-jumped task is executed.

[0074] Step S30, after detecting that the current task is normally running, the current task is continued to be executed, and the current task is displayed on the display screen.

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

[0076] The embodiment can effectively avoid the problem that the MCU cannot light up the instrument due to the SoC fault of the vehicle machine during the driving process, ensure the normal display of the instrument when the vehicle instrument appears a black screen fault, and improve the safety of user driving.

[0077] Further, Figure 3 As shown in FIG. 6, the second embodiment of the vehicle machine black screen software redundancy lighting method is proposed based on the first embodiment, and in the embodiment, the step S10 specifically includes the following steps. Figure 3

[0078] Step S11, all tasks of the current vehicle machine are acquired, and the all tasks include a current execution task, a task to be jumped, and a non-execution task.

[0079] It should be noted that all tasks of the current vehicle machine are tasks corresponding to all programs pre-set in the vehicle machine, and the all tasks include a current execution task, a task to be jumped, and a non-execution task.

[0080] Step S12, a RAM shared data area of the current execution task and the task to be jumped is established, and all codes are stored in different areas of the vehicle machine memory ROM.

[0081] It can be understood that the random access memory (RAM) shared data area of the current execution task and the task to be jumped is established, and all codes can be stored in different areas of the vehicle machine solid-state semiconductor memory (Read Only Memory, ROM).

[0082] ​Through the above scheme, this embodiment obtains all tasks of the current vehicle computer, including currently executed tasks, tasks to be jumped to, and unexecuted tasks; establishes a RAM shared data area for the currently executed tasks and the tasks to be jumped to, and stores all the codes in different areas of the vehicle computer memory ROM; can store task codes in advance, effectively avoiding the problem of the MCU being unable to light up the instrument due to a vehicle computer SoC failure during driving, and improves the speed and efficiency of redundant lighting of the vehicle computer black screen software.

[0083] Further, Figure 4 This is a flow chart of the third embodiment of the vehicle computer black screen software redundant lighting method of the present invention, as shown in FIG. 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, 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, the code running state of the current task causing the display screen to be black is checked.

[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 status 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 and the code of the task to be jumped to 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, thereby executing the code of the task to be jumped to.

[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 to 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 failure or exception, a task with high priority can be selected from the to-be-jumped tasks as the target task; generally, the task with the highest priority is selected, and of course, the task most suitable for the current use scenario can also be selected as the target task, and the embodiment does not limit this, the code of the target task is executed, and the target task is displayed on the display screen.

[0094] Correspondingly, before the step S20, the car machine black screen software redundancy lighting method further includes the following steps:

[0095] Real-time detection or detection according to a preset detection period whether the current task has been restored to normal.

[0096] In specific implementation, referring to Figure 5 , Figure 5 The code storage logic diagram in the car machine black screen software redundancy lighting method of the application is shown in Figure 5 The second part of the scheme is specifically as follows: A realizes complete function logic, and B realizes necessary instrument function logic (independent of the SoC, only receiving necessary signals such as vehicle speed, rotating speed, gear, ready, partial fault light, partial function indicator light, etc.); when A fails, jump to B to work, and when A completes initialization and restores to normal, preferentially jump from B to A. The RAM shared data area of A and B tasks is established.

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

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

[0099] Start-up process: at start-up, the entry points of code A and code B start to execute in time slices, and under normal circumstances, the instrument display only displays the A state. During the execution of code A, the running state of code A is checked regularly; if it is detected that code A fails or is abnormal, the core will switch the instrument display code B state. If it is detected that A runs normally or performs other fault handling operations.

[0100] Task management: each code instance can be regarded as a task; a task switching mechanism can be designed, so that the core can switch between two tasks under certain conditions (such as task priority change, resource demand, etc.); this may involve saving and restoring the context (such as register value, stack pointer, etc.) of the task.

[0101] Through the above scheme, this embodiment starts the code entry points for executing the current task and the task to be jumped to, and executes the codes of the current task and the task to be jumped to 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 out and the code of the task to be jumped to 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 This is a flow chart of the fourth embodiment of the vehicle computer black screen software redundant lighting method of the present invention, as shown in FIG. 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, 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 This is a schematic diagram of hardware control in the vehicle computer black screen software redundant lighting method of the present invention, as shown in FIG. Figure 7 As shown in the figure, the instrument backlight is redundantly designed and a 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. 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. At the same time, specific logical control of the instrument function by different tasks is realized. An additional control channel is added in the 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 to, and executes the codes of the current task and the task to be jumped to 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 to is executed. After detecting that the current task is normal, the execution of the current task can be quickly resumed, which can effectively avoid the problem that the MCU cannot light up the instrument due to a vehicle computer SoC fault during driving of the vehicle, and when a black screen fault occurs on the vehicle instrument, the normal display of the instrument is guaranteed, thereby improving the driving safety of the user.

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