[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0038] Specifically, in order to solve the problems of the prior art, the embodiments of the present application provide a method, device, vehicle, storage medium and program product for displaying vehicle information. The method for displaying vehicle information provided by the embodiments of the present application is first introduced below.

[0039] Figure 1 A flow chart of a method for displaying vehicle information provided by an embodiment of the present application is shown. The method comprises the following steps:

[0040] S110, detect whether the vehicle is in a charge and discharge standby mode, and if so, determine the first moment when the vehicle enters the charge and discharge standby mode, wherein in the charge and discharge standby mode, the vehicle's entire power supply is in an off state, the internal power supply of the cockpit domain control unit is in a standby state, and the vehicle is in a charge and discharge state.

[0041] In this embodiment, when the vehicle is in the charging and discharging standby mode, the vehicle is performing a charging or discharging task, and the vehicle power supply is off, and the internal power supply of the cockpit domain control unit is on standby.

[0042] For example, the vehicle may be an electric vehicle, which includes an Intelligent Domain Control Unit (IDCU), a Central Control Unit (CCU), and a plurality of electronic control units (ECU_1 to ECU_N).

[0043] Among them, the vehicle's cockpit domain control unit (IDCU, Intelligent Domain Control Unit) is the core controller of the car's intelligent cockpit. It is responsible for the coordinated control of various systems in the cockpit, integrating and managing cockpit-related functions such as the instrument panel, central control screen, entertainment system, and voice interaction.

[0044] The cockpit domain control unit may include a microcontroller unit (MCU), a first operating system, and a second operating system. The first operating system may be an Android subsystem, and the second operating system may be a QNX subsystem. The microcontroller unit is the hardware core, responsible for running the basic control logic, for communicating with other modules and for scheduling tasks for each operating system. The first operating system and the second operating system are used to support the instrument display and touch screen interaction in the cockpit.

[0045] The vehicle domain control unit is used to exchange data with multiple ECUs through the CAN_FD bus and synchronize information with the IDCU. Each ECU is responsible for controlling a functional module of the vehicle. Functional modules may include engine, power, battery management system, and charging system. The ECU will send relevant data to the CCU through the CAN_FD bus, and the CCU will aggregate the data and pass it to the IDCU to ensure that the cockpit display can synchronously update the status information.

[0046] Inside the IDCU, the MCU distributes the data from the CCU to different operating systems, which display different information.

[0047] Specifically, when the power of the vehicle is in the off state, it can be the state when the vehicle is turned off or stops working. At this time, the vehicle's power system and some non-essential electronic systems have been turned off to save energy. The core functions of the vehicle (such as driving control, acceleration, braking, etc.) are not available. Only necessary low-power systems are kept running, such as: anti-theft alarm system, remote wake-up function and vehicle-mounted communication module, among which the vehicle-mounted communication module can include monitoring of the vehicle's charging status.

[0048] If the internal power supply of the CCU is in standby mode, it means that the CCU is in low-power operation, maintaining only some basic functions without complex calculations or display operations. The internal core module of the IDCU has not been completely shut down, but the operation state is limited to the lowest energy consumption mode. The microcontroller unit is still working, but only processes limited signal tasks.

[0049] Then, when it is detected that the vehicle's entire power supply is in the off state, the internal power supply of the cockpit domain control unit is in the standby state, and the vehicle is in the charging and discharging state, the vehicle can be considered to have entered the charging and discharging standby mode, and the first moment when the vehicle enters the charging and discharging standby mode can be recorded.

[0050] S120, within a first period after the first moment, detecting whether the micro control unit of the vehicle receives the power-related information sent by the electronic control unit in the vehicle, and if not, obtaining the first power-related information most recently received before the current moment.

[0051] S130: Display the first power-related information on a cockpit display screen.

[0052] In this embodiment, the power-related information is periodically sent from the ECU to the CCU via the CAN_FD bus, and the power-related information is updated and displayed on the cockpit domain display screen in each cycle. The first cycle duration is the duration of the first cycle, which is the cycle in which the cockpit domain control unit receives the power-related information.

[0053] The cockpit domain display screen is a display screen used for information interaction in the cockpit of the vehicle. The cockpit domain display screen is used to display vehicle-related information such as driving information, navigation information, battery-related information, and vehicle status information. Among them, the battery-related information may include battery percentage, cruising range, battery safety status, and battery charge and discharge status.

[0054] After the vehicle enters the charging and discharging standby mode, although the vehicle power is off and the internal power of the cockpit domain control unit is in standby mode, the cockpit domain display screen will not be turned off immediately. Instead, it will remain on for the first time after the vehicle enters the charging and discharging standby mode, and hide other content, only displaying the vehicle's power-related information, to ensure that users can understand the vehicle's power-related information after the vehicle enters the charging and discharging standby mode. The first time can be 30 seconds or 1 minute.

[0055] In this embodiment, the electronic control unit corresponding to the battery system in the vehicle will periodically send the power-related information to the micro control unit through the CAN_FD bus, and the micro control unit will then transmit the power-related information to the cockpit domain control unit.

[0056] That is to say, the cockpit domain control unit can periodically receive information related to power. If in the first duration, the cockpit domain control unit does not receive information related to power within the first cycle duration, that is, the cockpit domain control unit does not receive information related to power within a cycle, it can be considered that the information is lost, or there is a delay in transmission, or the electronic control unit corresponding to the battery system has entered a dormant state. In order to avoid the cockpit domain display screen displaying blank or erroneous data related to power, the cockpit domain control unit can obtain the first power related information that was successfully received the most recently, and display the first power related information on the cockpit domain display screen. Among them, the first cycle duration can be 100ms or 50ms.

[0057] In an embodiment of the present application, when the vehicle enters the charging and discharging standby mode, the first moment when the vehicle enters the mode is recorded. If the microcontroller unit fails to receive the power-related information sent by the electronic control unit in a certain receiving cycle after the first moment, the first power-related information that was successfully received the most recently is obtained from the storage, and the information is displayed on the cockpit domain display screen to ensure the continuous visibility of the power status. In this way, even if the power-related information is not uploaded to the vehicle's microcontroller unit in time, the system can still display the most recent valid data to avoid blank or error information on the display screen, which can facilitate users to intuitively understand the vehicle's power-related information during the charging and discharging process, improve the transparency of the charging and discharging operation, and improve the visual feedback of the charging and discharging process.

[0058] As an optional embodiment, after displaying the first power-related information on the cockpit domain display screen, the method further includes:

[0059] When the micro control unit of the vehicle receives the second power-related information sent by the electronic control unit in the vehicle, the second power-related information is displayed on the cockpit domain display screen.

[0060] In this embodiment, when the vehicle is in the charging and discharging standby mode, if the vehicle's microcontroller unit receives the latest second power-related information from the electronic control unit, the cockpit domain display screen will promptly display the second power-related information to ensure that the cockpit domain display screen displays the latest current power status of the vehicle. In this way, by receiving and updating power-related information in real time, it is ensured that the displayed content is consistent with the actual battery status.

[0061] Through the above method, the real-time and accuracy of the display of power-related information can be improved, avoiding data delays or errors.

[0062] As an optional embodiment, after displaying the first power-related information on the cockpit domain display screen, the method further includes:

[0063] When the time after the first moment reaches the preset display time of the cockpit domain display screen, the cockpit domain display screen is turned off.

[0064] In this embodiment, after the vehicle enters the charging and discharging standby mode, the cockpit domain display screen will display information related to the vehicle's power level, such as the power percentage or the vehicle's cruising range, within a first period of time after the first moment of entering the charging and discharging standby mode. When the first period of time ends, the system will automatically turn off the cockpit domain display screen and enter the screen-off state to avoid unnecessary energy consumption caused by the cockpit domain display screen working for a long time.

[0065] In this embodiment, displaying power-related information within the first duration can meet the user's need to obtain power-related information. After meeting the user's need to obtain power-related information, the system can reduce energy consumption by automatically turning off the screen.

[0066] As an optional embodiment, the detecting whether the vehicle is in the charging and discharging standby mode, and if so, determining the first moment when the vehicle enters the charging and discharging standby mode includes:

[0067] Detecting whether the vehicle is in a charge-discharge standby mode, and if the vehicle enters the charge-discharge standby mode from a low power consumption mode, determining the first moment when the vehicle enters the charge-discharge standby mode, turning on the cockpit domain display screen, and waking up the electronic control unit corresponding to the power-related information;

[0068] The method further comprises:

[0069] If the micro control unit of the vehicle receives the power-related information sent by the electronic control unit in the vehicle within a first period after the first moment, the power-related information is displayed on the cockpit domain display screen;

[0070] Among them, the low power consumption mode is that the whole vehicle power supply of the vehicle is in the off state, the internal power supply of the cockpit domain control unit is in the standby state, and the vehicle is not in the charging or discharging state.

[0071] In this embodiment, the vehicle is in low power consumption mode, the vehicle power is turned off, the internal power of the cockpit domain control unit is in standby mode, and the vehicle is not charged or discharged. At this time, the cockpit domain display screen is off.

[0072] If the vehicle is in low power mode and it is detected that the vehicle has started charging or discharging, the vehicle will enter the charging and discharging standby mode from the low power mode. At this time, the system will first wake up the cockpit domain display screen and wake up the electronic control unit related to the power information. After waking up the electronic control unit, the electronic control unit will send the current power information to the micro control unit. After the micro control unit receives the power information, the micro control unit will display the received power information on the cockpit domain display screen.

[0073] In an embodiment of the present application, when the vehicle switches from a low power consumption mode to a charging and discharging standby mode, the electronic control unit and the cockpit display screen can be promptly awakened to display power-related information in a timely manner, providing the user with intuitive charging or discharging status monitoring.

[0074] As an optional embodiment, the method further includes:

[0075] When the vehicle's entire power supply is in a partially powered-on state, a fully powered-on state or a remote wake-up state, if the vehicle's microcontroller unit does not receive power-related information sent by the electronic control unit in the vehicle within a first cycle, a warning message about the power-related information is displayed.

[0076] In this embodiment, when the vehicle is in the local power on state, the vehicle's power system is not activated, but some electronic systems and functional modules are powered on. Accordingly, the vehicle cannot be driven, but the cockpit domain devices corresponding to the cockpit domain control unit such as the instrument panel, central control screen, and air conditioning are powered on and can be used normally.

[0077] When the vehicle is in a fully powered (Ready) state, the power system and all functional modules in the vehicle are activated, and the vehicle can be driven and used normally.

[0078] When the vehicle is in the remote wake-up (Remote On) state, the vehicle is awakened remotely, some functional modules such as the cockpit domain equipment are activated, but the power system is not activated.

[0079] Therefore, whether in a partial power-on state, a full power-on state or a remote wake-up state, the vehicle's cockpit domain functions are in a working state, and the electronic control unit corresponding to the power-related information is also in a normal working state.

[0080] If in the above states, the power-related information sent by the electronic control unit is still not received within a first cycle, it can be considered that there is a fault in the CAN signal, a connection problem or a communication interruption; or, there is a fault in the electronic control unit corresponding to the power-related information. Therefore, a warning message about the power-related information can be displayed on the cockpit domain display. The warning message can be a text-based warning message, a placeholder or a default value. It is used to indicate that there is a fault in the reporting of power-related information.

[0081] Thereafter, if the micro control unit of the vehicle resumes receiving the power-related information sent by the electronic control unit in the vehicle, the received power-related information is displayed.

[0082] In the embodiment of the present application, by real-time monitoring of the reception of power-related information when the vehicle is in a partial power-on, full power-on or remote wake-up state, it is ensured that when the power-related information sent by the electronic control unit is not received within the first cycle, a warning message is displayed in time. This can remind the user that there may be anomalies in the current power-related information, avoiding the driver's misjudgment of the vehicle status due to missing or incorrect data.

[0083] As an optional embodiment, after displaying the warning information of the power-related information, the method further includes:

[0084] When the micro control unit of the vehicle receives the third power-related information sent by the electronic control unit in the vehicle, the warning information is canceled and the third power-related information is displayed on the cockpit domain display screen.

[0085] In this embodiment, when the vehicle micro control unit (MCU) re-receives the third power related information from the electronic control unit (ECU), the warning message previously displayed due to signal loss is canceled, and the latest received third power information is updated and displayed on the cockpit domain display screen.

[0086] This ensures that the cockpit display screen quickly switches to normal status after the signal is restored, improves the real-time and reliability of information display, avoids user confusion caused by delayed clearing of warning information, and enhances user trust in the vehicle's intelligent system.

[0087] Based on the vehicle information display method provided in the above embodiment, the present application also provides a specific implementation of a vehicle information display device. Please refer to the following embodiment.

[0088] See first Figure 2 The vehicle information display device 200 provided in the embodiment of the present application includes the following modules:

[0090] A first acquisition module is used to detect whether the micro control unit of the vehicle receives the power-related information sent by the electronic control unit in the vehicle within a first period after the first moment, and if not, to acquire the first power-related information most recently received before the current moment;

[0091] The first display module is used to display the first power-related information on a cockpit domain display screen.

If the microcontroller unit fails to receive the power-related information sent by the electronic control unit in a certain receiving cycle after the first moment, the first power-related information received successfully the most recently is obtained, and the first power-related information is displayed on the cockpit domain display screen to ensure the continuous visibility of the power status. In this way, even if the power-related information is not uploaded to the vehicle's microcontroller unit in time, the system can still display the most recent valid data to avoid blank or error information on the display screen, which can facilitate users to intuitively understand the vehicle's power-related information during the charging and discharging process, improve the transparency of the charging and discharging operation, and improve the visual feedback of the charging and discharging process.
