[0054] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0055] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0056] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.
[0057] The present application provides a vehicle instrument display system that can be set in a vehicle. When a display failure occurs in a main instrument conventionally set in the vehicle, a sub-instrument pre-set in the vehicle instrument display system serves as a backup instrument for the main instrument and continues to display driving safety information of the vehicle during driving.
[0058] In actual applications, after the driver starts the vehicle, the cockpit domain microcontroller unit (Domain Control Unit, DHU) calculates the vehicle's driving safety information and transmits it to the instrument display module, and displays it through the instrument display in the instrument display module, so that the driver can know the vehicle's driving safety information in real time during driving to ensure driving safety. However, as the driver's demand for vehicle display functions increases, the instrument functions become more complex, resulting in an increase in the failure rate of the instrument. As a safety component of the vehicle, once the instrument display function fails, the driver will not be able to know the current vehicle speed and vehicle fault light information during driving, which may cause the vehicle to exceed the speed limit or even a vehicle accident, posing a great safety hazard to the driver.
[0059] In response to the above technical problems, the vehicle display module of the technical solution provided in the present application configures a main instrument display and a sub-instrument display at the same time when configuring the instrument display; if a display failure is detected in the main instrument display during driving, the sub-instrument display can be immediately controlled to perform a backup display, so that the driver can continue to know the vehicle's driving safety information, reduce safety hazards to the driver during driving, and improve the driver's driving safety.
[0060] Figure 1 This is a schematic diagram of the structure of a vehicle instrument display system provided in an embodiment of the present application. Figure 1 As shown, the system 100 includes an instrument display module 10 and a cockpit domain control module 20; the instrument display module 10 includes a main instrument display unit 11 and a sub-instrument display unit 12; the sub-instrument display unit 12 includes a sub-instrument display 122; the cockpit domain control module 20 is respectively connected to the main instrument display unit 11 and the sub-instrument display 122.
[0061] Specifically, the cockpit domain control module 20 controls the main instrument display unit 11 to display the first information and controls the auxiliary instrument display 122 to display the second information when it is determined that the main instrument display unit 11 displays normally; the cockpit domain control module 20 also controls the auxiliary instrument display 122 to backup and display the first information when it is determined that a display failure occurs in the main instrument display unit 11.
[0062] In actual application, after the vehicle is started, the cockpit domain control module 20 in the vehicle instrument display system will calculate the driving parameters collected by the vehicle during driving and obtain the environmental information of the current driving section, and then determine the driving safety information of the vehicle during driving according to the driving parameters and environmental parameters, and transmit the driving safety information to the main instrument display unit 11 in the instrument display module 10, that is, control the main instrument display unit 11 to display the driving safety information, that is, the first information. Exemplarily, the first information may include but is not limited to the vehicle speed information, speed limit information, power information and warning light information required during driving.
[0063] In order to improve the riding experience of the driver and passengers in the vehicle, the cockpit domain control module 20 will also control the auxiliary instrument display 122 to display the second information, i.e., one or more of the vehicle's surrounding environment information, entertainment information and news information according to the user's pre-set settings; optionally, the auxiliary instrument display 122 can be a display device generated by an LCD display screen, etc. The auxiliary instrument display 122 can be displayed when triggered by the user, or it can be automatically awakened to display the second information when the conditions are met according to the pre-set conditions.
[0064] During the display process of the main instrument display unit 11, in order to ensure the continuous display of driving safety information, the main instrument display unit 11 will perform display fault monitoring. For example, a timed detection task is pre-set, and fault detection is performed after a preset time period to determine whether the main instrument display unit 11 has a display fault.
[0065] Optionally, during the fault monitoring process of the main instrument display unit 11, if no display fault is detected, the cockpit domain control module 20 continues to transmit the first information to the main instrument display unit 11 for display, and transmits the second information to the auxiliary instrument display 122 for display; conversely, if a display fault is detected, the detected fault signal is transmitted to the cockpit domain control module 20, and then the cockpit domain control module 20 determines that a display fault occurs in the main instrument display unit 11 based on the received fault signal, that is, it determines that the main instrument display unit 11 cannot continue to display information. In order to ensure driving safety, the auxiliary instrument display 122 is controlled to replace the main instrument display unit 11 to perform a backup display of the vehicle's driving safety information.
[0066] Optionally, when determining that a display failure occurs in the main instrument display unit 11 , the cockpit domain control module 20 may send the first information to the auxiliary instrument display 122 for information display, thereby controlling the auxiliary instrument display 122 to back up and display the first information.
[0067] The vehicle instrument display system provided in the present application is provided with an instrument display module 10 and a cockpit domain control module 20; the instrument display module 10 includes a main instrument display unit 11 and a sub-instrument display unit 12; the sub-instrument display unit 12 includes a sub-instrument display 122; wherein, the main instrument display unit 11 displaying the first information is monitored for display faults, and when a display fault is detected, that is, when it is determined that a display fault occurs in the main instrument display unit 11, a fault signal is transmitted to the cockpit domain control module 20; and then the cockpit domain control module 20 transmits the first information to the sub-instrument display 122, so as to control the sub-instrument display 122 to perform information backup display, so that the driver can continuously know the status information of the vehicle, reduce the safety hazards of the driver during driving, and improve the driving safety of the driver.
[0068] Figure 2 This is a schematic diagram of another vehicle instrument display system provided in an embodiment of the present application. Figure 2 As shown, on the basis of the above-mentioned embodiments, the cockpit domain control module 20 includes a cockpit domain controller 21 and a cockpit domain micro-control unit 22; the main instrument display unit 11 includes a main instrument controller 111 and a main instrument display 112; the main instrument controller 111 is respectively connected to the main instrument display 112 and the cockpit domain controller 21; the cockpit domain micro-control unit 22 is also respectively connected to the cockpit domain controller 21, the main instrument display 112 and the auxiliary instrument display 122.
[0069] Specifically, the cockpit domain micro-control unit 22 transmits the first information to the main instrument display 112 and the second information to the auxiliary instrument display 122 after startup; the main instrument controller 111 performs display detection on the main instrument display 112, and when it is detected that the main instrument display 112 displays normally, controls the main instrument display 112 to display the first information; the main instrument display 112 receives and displays the first information; the auxiliary instrument display 122 receives and displays the second information.
[0070] In actual applications, the main instrument display 112 may be a display device generated by an LCD display screen, etc., for displaying the first information, i.e., the driving safety information of the vehicle; the main instrument controller 111 may be a control device implemented by an MCU, for performing display control and display fault monitoring on the main instrument display 112. The cockpit domain controller 21 may be an MCU chip pre-configured in the cockpit domain control module 20, and of course it may also be other control devices. This application does not specifically limit the implementation device of the cockpit domain controller 21. The cockpit domain microcontroller unit 22 (Domain Control Unit, DHU) is a control chip set in the cockpit domain control module 20, and is used to calculate and transmit specific parameters in the vehicle.
[0071] In an embodiment of the present application, after the vehicle is started, the cockpit domain micro-control unit 22 determines the first information and the second information that need to be displayed, sends the first information to the main instrument display 112, and sends the second information to the auxiliary instrument display 122. Optionally, the auxiliary instrument display directly receives and directly displays the second information transmitted by the cockpit domain micro-control unit 22. The main instrument display 112 receives the first information transmitted by the cockpit domain micro-control unit 22. In order to ensure driving safety, it is necessary to confirm in advance whether the main instrument display 112 can display normally before the main instrument display 112 displays the first information. Therefore, the main instrument controller 111 can be used to perform display fault detection on the main instrument display 112. Optionally, when the main instrument controller 111 detects that the main instrument display is displaying normally, it controls the main instrument display 112 to display the first information.
[0072] Optionally, when the main instrument controller 111 detects that a display failure occurs in the main instrument display 112, it sends the detected fault signal to the cockpit domain controller 21; the cockpit domain controller 21 generates a backup display signal corresponding to the first information according to the received fault signal, and transmits the backup display signal to the cockpit domain micro-control unit 22. When the cockpit domain micro-control unit 22 receives the backup display signal, it can confirm that the main instrument display 112 can no longer display the first information. In order to realize information display, the first information needs to be sent to a preset backup display for display, that is, sent to the auxiliary instrument display 122 for backup display.
[0073] Optionally, the auxiliary instrument display 122 may display only the first information alone in the display; or may display the first information and the second information together in the display. In the embodiment of the present application, no specific limitation is imposed on the display content of the auxiliary instrument display 122 .
[0074] It should be noted that CAN or LIN is used to transmit signals between the cockpit domain controller 21 and the main instrument controller 111 .
[0075] The vehicle instrument display system provided in the present application, on the basis of the above, the main instrument display unit 11 includes a main instrument controller 111 and a main instrument display 112; the cockpit domain control module 20 includes a cockpit domain controller 21 and a cockpit domain micro-control unit 22; when the main instrument controller 111 detects that a display fault occurs in the main instrument display 112, the fault signal is transmitted to the cockpit domain controller 21; further, the cockpit domain controller 21 generates a backup display signal according to the fault signal, and transmits the backup display signal to the cockpit domain micro-control unit 22; so that the cockpit domain micro-control unit 22 controls the auxiliary instrument display 122 to replace the main instrument display 112 to back up and display the first information, thereby ensuring that the vehicle continues to display the vehicle's driving safety information during driving, thereby reducing the safety hazards of the driver during driving and improving the driver's driving safety.
