The predetermined period is a period for collecting data related to driving safety, which is set according to actual conditions or demands, and may be, for example, 50ms (milliseconds). The driving safety related data may be driving safety related signals or driving safety related information, which is not limited in the embodiment of the present application. The driving safety related signals can be tire pressure signals, voltage signals, current signals and/or brake signals, and the embodiment of the application is not limited to the tire pressure signals, the voltage signals, the current signals and/or the brake signals; the information related to driving safety may be fuel consumption information, speed information and/or oil temperature information, which is not limited in the embodiment of the present application.

In particular, the MCU120 may collect driving safety-related data at predetermined periods through a data collection device, which may be a controller area network (ControllerAreaNetwork, CAN) or a plurality of types of sensors, for example, an intake pressure sensor, a vehicle speed sensor, an engine oil pressure sensor, a water temperature sensor, an airbag sensor, a brake sensor, and/or the like.

If it is determined that the operation state of the main display module 131 is normal according to the received information, the image display information related to the driving safety is transmitted to the meter screen 140 through the main display module 131. If the working state of the main display module 131 is abnormal according to the received information, stopping the process of the main display module 131, and then judging whether the working state of the standby display module 132 is normal according to the received information; if the working state of the standby display module 132 is normal, sending an instruction to the standby display module 132 to start the standby display module 132, then sending image display information related to driving safety to the instrument screen 140 through the standby display module 132, judging whether the working state of the main display module 131 is normal or not, if the working state of the main display module 131 is normal, stopping the process of the standby display module 132, simultaneously starting the main display module 131, and then sending the image display information related to driving safety to the instrument screen 140 through the main display module 131; if the operation state of the standby display module 132 is abnormal, an instruction is sent to the MCU120, and the SOC130 is restarted by the MCU 120.

Fig. 2 is a schematic structural diagram of an automobile instrument display control system according to a second embodiment of the present application, and as shown in fig. 2, the automobile instrument display control system 110 may include: including an MCU120, an SOC130, and an instrument screen 140. Wherein, the MCU120 may be connected with the SOC130, the SOC130 may be connected with the instrument screen 140, and the SOC130 may include: a primary display module 131, a standby display module 132, a monitoring module 133, a log module 134, and a display control module 135.

The MCU120 is further configured to directly send the driving safety related data to the main display module 131 and the standby display module 132 if the driving safety related data does not need to be processed;

the standby display module 132 is further configured to generate driving safety related image display information according to the driving safety related data, and send the driving safety related image display information to the instrument screen 140.

Specifically, the MCU120 may collect driving safety-related data at predetermined periods through a data collection device, which may be a CAN or a plurality of types of sensors, for example, an intake pressure sensor, a vehicle speed sensor, an engine oil pressure sensor, a water temperature sensor, an airbag sensor, a brake sensor, and/or the like. If the collected data related to driving safety does not need to be processed, for example: the collected data related to the driving safety is a digital signal or one/more pieces of alarm information, and the data related to the driving safety is directly sent to the main display module 131 and the standby display module 132 through the connection interface.

After receiving the data related to the driving safety sent by the MCU120, the main display module 131 and the standby display module 132 generate image display information related to the driving safety based on the received data related to the driving safety, where the main display module 131 and the standby display module 132 respectively generate image display information related to the driving safety according to an image display mapping table set in advance in themselves. The image display mapping table is obtained through a software program written in advance. Then, the working states of the two display modules are monitored through the monitoring module 133, if the working state of the main display module 131 is normal, the main display module 131 sends the image display information related to the driving safety to the instrument screen 140 through the connection interface, and the standby display module 132 caches the image display information related to the driving safety; if the working state of the main display module 131 is abnormal, the standby display module 132 sends the image display information related to the driving safety to the instrument screen 140 through the connection interface.

For example, the predetermined period is 40ms, the mcu120 may collect data related to driving safety through the CAN every 40ms, and if the collected data related to driving safety is an alarm message with overhigh water temperature, the data may be directly sent to the active display module 131 and the standby display module 132 through the SPI interface.

The standby display module 132 buffers the icon information.

In this embodiment, the MCU120 collects data related to driving safety, and directly sends the data related to driving which does not need to be processed to the main display module 131 and the standby display module 132, so that data transmission efficiency is improved, time is saved, cost is reduced, and a data base is provided for displaying the instrument screen 140.

In addition, the MCU120 may collect data not related to driving safety through a data acquisition device according to a predetermined period, and the data acquisition device may be a CAN or a plurality of types of sensors, for example, the plurality of types of sensors may be an odometer sensor, an air conditioner sensor, and the like. If the collected data which are not related to the driving safety do not need to be processed, the data which are not related to the driving safety are directly sent to the main display module 131 and the standby display module 132 through the connection interface.

After receiving the data related to the driving safety sent by the MCU120, the main display module 131 and the standby display module 132 generate image display information related to the driving safety based on the received data related to the driving safety, the main display module 131 generates the image display information related to the driving safety according to an image display mapping table set in advance in the main display module 132, and the standby display module 132 does not process the image display information. The image display mapping table is obtained through a software program written in advance. If the working state of the main display module 131 is normal, the main display module 131 sends the image display information irrelevant to the driving safety to the instrument screen 140 through the connection interface.

Image display information irrelevant to driving safety is generated through the main display module 131, and physical examination of a user is improved under the condition that driving safety of the user is ensured.

The MCU120 is specifically configured to determine whether the analog signal is within a corresponding safety range if the data related to driving safety is an analog signal, and determine that the data related to driving safety does not need to be processed if the analog signal is within the corresponding safety range; if the analog signal is not in the corresponding safety range, judging that the data related to the driving safety need to be processed.

Specifically, if the data related to driving safety collected by the MCU120 through the data collecting device is an analog signal, determining whether the analog signal is in a corresponding safety range, and if the analog signal is in the corresponding safety range, determining that the data related to driving safety does not need to be processed; for example, the normal range of automotive battery voltages is 13.5 to 14.5V, and if the collected voltage value is 14V, the data need not be processed. If the analog signal is not in the corresponding safety range, judging that the data related to the driving safety need to be processed. For example, if the voltage value collected is 13V, it can be processed by a program written in advance in the MCU120 to generate an alarm message of too low voltage.

In this embodiment, the MCU120 directly performs judgment processing on the analog signal, and generates alarm information according to the processing result, thereby improving the working efficiency of the automobile instrument.

For example, when the monitoring module 133 monitors that the working states of the active display module 131 and the standby display module 132 are abnormal, the power pin of the SOC130 may be reset by the MCU120, so that the SOC130 is restarted.

The monitoring module 133 is further configured to record fault information of the main display module 131 if the working state of the main display module 131 is abnormal; the fault information of the main display module 131 at least includes: fault occurrence location, fault form, and fault time;

the log module 134 is configured to receive the fault information of the primary display module 131 sent by the monitoring module 133 and send the fault information of the primary display module 131 to the cloud server in real time through the vehicle-to-machine network.

Specifically, when the monitoring module 133 monitors that the working state of the main display module 131 is abnormal, fault information of the main display module 131 is recorded, and the information is sent to the log module 134 in real time; the log module 134 receives the fault information of the main display module 131, and then sends the fault information to the cloud server in real time through the vehicle-to-machine network.

In this embodiment, the log module 134 receives the fault information and sends the fault information to the cloud server in real time through the vehicle-to-machine network, so that technicians can find problems in time, quickly locate and solve the problems, and loss of users is reduced.

The monitoring module 133 is further configured to record fault information of the standby display module 132 if the working state of the standby display module 132 is abnormal; wherein, the fault information of the standby display module 132 at least includes: fault occurrence location, fault form, and fault time;

the log module 134 is configured to receive the fault information of the standby display module 132 sent by the monitoring module 133 and send the fault information of the standby display module 132 to the cloud server in real time through the vehicle-to-machine network.

Specifically, when the monitoring module 133 monitors that the working state of the standby display module 132 is abnormal, fault information of the standby display module 132 is recorded, and the information is sent to the log module 134 in real time; the log module 134 receives the fault information of the standby display module 132 and then sends the fault information to the cloud server in real time through the vehicle-to-machine network, so that a technician can be informed of the fault in time when the fault occurs to analyze the fault.

The display control module 135 is configured to receive the image display information related to driving safety sent by the main display module 131 and send the image display information related to driving safety to the instrument screen 140 when the working state of the main display module 131 is normal; when the operation state of the main display module 132 is abnormal, the image display information related to the driving safety sent by the standby display module 132 is received, and the image display information related to the driving safety is sent to the instrument screen 140.

In this embodiment, the image display information related to driving safety generated by the display module is received by the display control module 135 and transmitted to the meter screen 140 to cause the meter screen 140 to display the image information. Compared to directly transmitting the driving safety related image display information to the meter screen 140 through the display module, the operation of the meter screen 140 that needs to be switched back and forth and which display module is connected is reduced.

According to the automobile instrument display control system provided by the embodiment of the application, the MCU is used for collecting data related to driving safety according to a preset period; if the data related to the driving safety needs to be processed, the data related to the driving safety is processed, and the processed data related to the driving safety is respectively sent to the main display module and the standby display module; if the data related to the driving safety do not need to be processed, the data related to the driving safety are directly sent to the main display module and the standby display module; then the main display module generates driving safety related image display information according to the processed or unprocessed driving safety related data, and the standby display module also generates driving safety related image display information according to the processed or unprocessed driving safety related data; then monitoring working states of the main display module and the standby display module through the monitoring module; when the working state of the main display module is monitored to be normal, the image display information related to driving safety is sent to the display control module through the main display module; when the working state of the main display module is abnormal, sending the image display information related to driving safety to the display control module through the standby display module; recording fault information of the main display module; the fault information of the main display module at least comprises: fault occurrence location, fault form, and fault time; and finally, receiving the image display information related to the driving safety sent by the display control module through the instrument screen, and displaying the image display information related to the driving safety.

In addition, the application integrates the main display module and the standby display module on one piece of hardware, thereby greatly reducing the cost. In addition, the dual-module system has more advantages compared with the single-module system in the recovery process when the abnormality occurs. When an abnormality occurs in a single-module system, the problem can be solved only by a restarting mode, the restarting process is generally longer, and even if the restarting process can be resumed after the restarting process, blank interruption on the instrument display in the period of time can be caused, so that a driver cannot receive information in time, and the method has a great hidden danger on driving safety; if the system is not restored after the restart, the system is substantially paralyzed. Under the dual-module system, if the main display module is abnormal, the standby display module is immediately switched to at the moment, and the instrument display is not interrupted. In addition, the technical scheme of the embodiment of the application is simple and convenient to realize, convenient to popularize and wider in application range.

In this embodiment, the display control module receives the image display information related to driving safety generated by the display module, and sends the image display information to the meter screen so that the meter screen displays the image information. Compared with the method that the display module directly sends the image display information related to driving safety to the instrument screen, the method reduces the operation that the instrument screen needs to be switched back and forth and which display module is connected.
