[0002] Since the vehicle-mounted electronic device needs to meet the safety requirements of driving, the vehicle-mounted electronic device needs to meet the ASIL B safety level. The current solution usually determines the existence of a specific display fault in the display processing unit by monitoring the cyclic redundancy check value of the system on chip. When the display is not normal, it can be found by calculating the cyclic redundancy check value. At this time, the vehicle information processor (VIP) can be restarted or the display can be blacked out to cope with it.

[0003] Although such a solution seems to achieve the safety requirements of the ASIL B safety level, its implementation effect depends on the performance of the system on chip. If the performance of the system on chip is not high enough, it will often cause the interruption or delay of the cyclic redundancy check, which is not conducive to the implementation of functional safety. Furthermore, when the vehicle information processor (VIP) detects such interruption or delay, it can only cope with it by triggering the system to enter a safe state, thereby causing the system to frequently black out or restart. Such a coping solution is not user-friendly for the user of the vehicle, and it also has an adverse effect on driving safety. SUMMARY

The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0041] As mentioned above, in order to solve the technical problem in the prior art, i.e. how to replace the black screen or restart to achieve a higher safety level of the vehicle, the inventors of the present disclosure have innovatively conceived a way to achieve the above-mentioned purpose, i.e. the vehicle information processor VIP outputs a warning signal to the display LCD via an independent communication link or the co-processor outputs an instruction to the display processing unit DPU via an independent communication link to make the display re-display, thereby improving the driving safety and user friendliness.

[0042] In general, the first aspect of the present disclosure proposes a display warning method for a vehicle, wherein the vehicle comprises a vehicle information processor VIP and a system on chip SOC for controlling a display LCD, wherein the system on chip SOC comprises a display processing unit DPU for controlling the display LCD and a human-machine interface and a safety display monitor arranged between the vehicle information processor VIP and the display processing unit DPU, the display warning method comprising: determining, by the vehicle information processor, whether there is a display failure; and in the case of a display failure, outputting, by the vehicle information processor, a warning signal to the display via an independent communication link. In the display warning method according to the present disclosure, the black screen is replaced by a warning signal, thereby significantly improving the driving safety.

[0043] In addition, the second aspect of the present disclosure proposes, in general, a display warning method for a vehicle, wherein the vehicle comprises a vehicle information processor (VIP), a system on chip (SOC) for controlling a liquid crystal display (LCD), the system on chip (SOC) comprising a display processing unit (DPU) for controlling the liquid crystal display (LCD) and a main processor and a co-processor disposed between the vehicle information processor (VIP) and the display processing unit (DPU), the display warning method comprising: determining, by the co-processor, whether there is a display failure; and in the case of a display failure, outputting, by the co-processor, an indication for the display to re-display to the display processing unit (DPU) via an independent communication link. In the display warning method according to the present disclosure, the black screen is replaced by outputting an indication for the display to re-display, thereby significantly improving driving safety.

[0044] The display warning method for a vehicle, the display warning device for a vehicle and the computer readable storage medium for implementing the display warning method for a vehicle according to the present disclosure will be described below in conjunction with the accompanying drawings. Among them, Figure 1 The block schematic diagram of the hardware device for implementing the display warning method for a vehicle according to one embodiment of the present disclosure is schematically shown, Figure 2 The block schematic diagram of the hardware device for implementing the display warning method for a vehicle according to another embodiment of the present disclosure is schematically shown, Figure 3 The flow schematic diagram of the display warning method 300 for a vehicle according to one embodiment of the present disclosure is schematically shown, Figure 4 The flow schematic diagram of the display warning method 400 for a vehicle according to another embodiment of the present disclosure is schematically shown, Figure 5 The structural schematic diagram of the display warning device 500 for a vehicle according to another embodiment of the present disclosure is schematically shown, and Figure 6 The structural schematic diagram of the display warning device 600 for a vehicle according to another embodiment of the present disclosure is schematically shown.

[0045] From Figure 1 It can be seen from among them, in terms of hardware architecture, Figure 1The hardware apparatus for implementing the display warning method for a vehicle according to one embodiment of the present disclosure comprises a vehicle information processor VIP 110 and a system on chip SOC 120 for controlling a display LCD 130, the system on chip SOC 120 comprising a main processor 121 and a coprocessor 122 disposed between the vehicle information processor VIP 110 and a display processing unit DPU 125 for controlling the display LCD 130. Initially, the vehicle information processor VIP 110 issues a display state instruction 111 to the main processor 121, which then sends a display control instruction 1211 to the display processing unit DPU 125 accordingly, followed by sending a display instruction 1251 to the display LCD 130 by the display processing unit DPU 125. After this process, the vehicle information processor VIP 110 can send a display state query instruction 112 to the coprocessor 122, which can then send a cyclic redundancy check instruction 1221 to the display processing unit DPU 125 and receive a cyclic redundancy check feedback instruction 1222 and determine whether there is a display failure of the display LCD 130 accordingly, and if there is a display failure, it can attempt to resolve the failure by causing the display LCD 130 to re-display, for example, by sending a re-display instruction 1223 to the display processing unit DPU 125. Here, the modules shown in dashed lines (e.g. the vehicle information processor VIP 110, the coprocessor 122 and the display processing unit DPU 125) and the communications therebetween need to meet the safety level of ASIL B, while other modules and the communications therebetween, for example, only need to meet the functional safety level of QM.

After this process, the vehicle information processor (VIP) 210 can send a cyclic redundancy check (CRC) instruction 2101 to the display monitor (SDM) 222, which in turn sends a CRC instruction 2221 to the display processing unit (DPU) 225 and receives a CRC feedback instruction 2222 and forwards 2102 it to the vehicle information processor (VIP) 210, and the vehicle information processor (VIP) 210 determines whether there is a display failure of the display (LCD) 230 accordingly, and if there is a display failure, it can attempt to resolve the failure by outputting a warning signal to the display (LCD) 230, for example, through a separate communication link 2103 between the vehicle information processor (VIP) 210 and the display (LCD) 230. Here, the modules shown in dashed lines (e.g., the vehicle information processor (VIP) 210 and the display (LCD) 230) and the communication therebetween need to meet the safety level of ASIL B, while other modules and the communication therebetween, for example, only need to meet the functional safety level of QM.
