[0056] The technical solutions in the present application will be described in detail below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist together, and B exists alone, and in addition, "multiple" in the description of the embodiments of the present application means two or more than two.

[0057] Hereinafter, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0058] It should be understood that in the present application, the target controller can be various controllers such as a transmission control unit (TCU), a brake control unit (BCU), a suspension control unit (SCU), etc.

[0059] In addition, the target controller is used to determine the display signal of the vehicle. For example, the TCU is used to determine the gear signal of the vehicle and send the gear signal to the display screen for display; the SCU is used to determine the body posture signal of the vehicle and send the body posture signal to the display screen for display.

[0060] It can be understood that the vehicle signal determined by the target controller shown above is only one way that can be used in actual application, and does not limit the vehicle signal determined by the target controller in actual application. The specific vehicle signal can be determined according to the actual situation, which is not limited here.

[0061] Figure 1is a framework schematic diagram of a vehicle control system provided by an embodiment of the present application.

[0062] It should be noted that in the present embodiment, only the transmission controller is described as the target controller, i.e., the signal transmission of the transmission controller, the multimedia host and the display screen is described.

[0063] As shown in the figure, Figure 1 The transmission controller (TCU) 101 of the vehicle is connected to the display screen 103 through the multimedia host (Head Unit, HUT) 102, and the transmission controller 101 sends vehicle signals to the display screen 103. However, the display signal of the display screen 103 needs to be processed, i.e., the multimedia host 102 sends the processed vehicle signal to the display screen 103 for display.

[0064] In the related art, the TCU in the vehicle sends a display signal to the display screen to enable the display screen to display. However, when the display signal fails to pass the verification during transmission, the display screen no longer displays, resulting in abnormal vehicle display function. In view of this, the present application provides a vehicle control method, a vehicle and a storage medium, which can avoid the abnormal vehicle display function caused by verification failure, thereby improving the driving safety of the vehicle.

[0065] Figure 2 is another framework schematic diagram of a vehicle control system provided by an embodiment of the present application.

[0066] It should be noted that in the present embodiment, only the transmission controller is described as the target controller, i.e., the signal transmission of the transmission controller, the multimedia host and the display screen is described.

[0067] As shown in the figure, Figure 2 As shown in the figure,

[0068] As shown in the figure, As shown in the figure, the first communication link of the transmission controller 101 in the vehicle and the second communication link of the transmission controller 101 are connected to the display screen 103, the first communication link includes the transmission controller 101, the multimedia host 102 and the display screen 103, and the transmission controller 101 is connected to the display screen 103 through the multimedia host 102; the second communication link includes the transmission controller 101, the target gateway (Serving Gateway, SGW) 201 and the display screen 103, and the transmission controller 101 is connected to the display screen 103 through the target gateway 201. As shown in the figure, the first communication link of the transmission controller 101 in the vehicle and the second communication link of the transmission controller 101 are connected to the display screen 103, the first communication link includes the transmission controller 101, the multimedia host 102 and the display screen 103, and the transmission controller 101 is connected to the display screen 103 through the multimedia host 102; the second communication link includes the transmission controller 101, the target gateway (Serving Gateway, SGW) 201 and the display screen 103, and the transmission controller 101 is connected to the display screen 103 through the target gateway 201. As shown in the figure, the first communication link of the transmission controller 101 in the vehicle and the second communication link of the transmission controller 101 are connected to the display screen 103, the first communication link includes the transmission controller 101, the multimedia host 102 and the display screen 103, and the transmission controller 101 is connected to the display screen 103 through the multimedia host 102; the second communication link includes the transmission controller 101, the target gateway (Serving Gateway, SGW) 201 and the display screen 103, and the transmission controller 101 is connected to the display screen 103 through the target gateway 201.

[0069] Specifically, if the target communication link is the first communication link, the target signal is sent to the multimedia host, and the second target check result of the target signal is determined by the multimedia host, and the display screen is controlled to display according to the second target check result; if the target communication link is the second communication link, the target signal is sent to the target gateway, and the second target check result of the target signal is determined by the target gateway, and the display screen is controlled to display according to the second target check result.

[0070] For example, assuming that the first signal is a gear signal; the TCU (transmission controller) sends the gear signal to the HUT (multimedia host), the gear signal carries a first value (Cyclic Redundancy Check, CRC value) and a second value (Rolling Counter, RC), the HUT checks the gear signal to obtain a first target check result, if the first target check result indicates that the check is successful, the gear signal is converted into an I2C signal (Inter-Integrated Circuit, transmission signal in the integrated circuit bus), and displayed on the display screen; if the first target check result indicates that the check fails, switch to the second communication link, and send the gear signal to the display screen through the second communication link, then check the gear signal (CAN signal) through the SGW to obtain a second target check result, if the second target check result indicates that the check is successful, the gear signal is converted into an I2C signal and displayed on the display screen.

[0071] Further, since the gear signal carries the first value and the second value, the gear signal is checked by the first value and the second value, which can ensure the accuracy of the gear signal.

[0072] It can be understood that the display screen does not have the ability to directly process the CAN signal, and the signals displayed on the display screen are all signals sent by the HUT or the SGW, and when the HUT or the SGW sends the display signal (for example, the second signal) to the display screen, the CAN signal needs to be converted into an I2C signal and then sent to the display screen for display.

[0073] Figure 3 is a schematic diagram of a first signal provided by an embodiment of the present application.

[0074] For example, as shown in Figure 3 The first 8 bits of the first signal (message) are the first value (CRC value), and the last 4 bits are the second value (RC value), which are checked by the CRC value and the RC value of the first signal to obtain a first target check result.

[0075] For example, the first target check result includes a first check result (a CRC value check result) and a second check result (an RC value check result). The first target check result is determined by the first check result and the second check result. For example, in a case where the first check result indicates that the check is successful and the second check result indicates that the check is successful, it is determined that the first target check result indicates that the check is successful.

[0076] For example, the HUT determines a first value in the first signal and calculates the first signal according to a preset algorithm to obtain a CRC check value. It is determined whether the first value is consistent with the CRC check value. When the first value is consistent with the CRC check value, it is determined that the check field check of the first signal is successful, and the first check result indicates that the check is successful. When the first value is not consistent with the CRC check value, it is determined that the check field check of the first signal fails, and the first check result indicates that the check fails. In this case, the first signal may be attacked or tampered.

[0077] For example, the HUT determines a second value in the first signal and a local RC value (an RC value of the HUT). It is determined whether the second value is consistent with the local RC value. When the second value is consistent with the local RC value, it is determined that the count field check of the first signal is successful, and the second check result is successful. When the second value is not consistent with the local RC value, it is determined that the count field check of the first signal fails, and the second check result fails. In this case, the first signal transmission may be stuck.

[0078] It should be noted that the RC value must be greater than the previous frame. If the RC value is less than the previous frame, it means that the signal is stuck during transmission, and the frame message is not fresh. In addition, the first signal can include one frame of signal or multiple frames of signal. If the first signal includes multiple frames of signal, in a case where the first target check results of the multiple frames of signal all indicate that the check fails, it is determined to switch to the second communication link.

[0079] It can be understood that not all transmission signals carry the first value and the second value. In a case where the transmission signal needs to be checked by end-to-end (E2E), the transmission signal carries the first value and / or the second value. In a case where the transmission signal does not need to be checked by end-to-end, the transmission signal does not carry the first value or the second value, and the transmission signal that does not need to be checked can be directly transmitted through the first communication link.

[0080] Figure 4 is a schematic flowchart of a vehicle control method provided by an embodiment of the present application.

[0081] For example, Figure 4The method shown can be executed by a target controller in a vehicle, the target controller being configured to determine a display signal of the vehicle; a first communication link comprising the target controller in the vehicle and a second communication link of the target controller, the first communication link comprising the target controller, a multimedia host and a display screen, the target controller being communicatively connected to the display screen through the multimedia host; the second communication link comprising the target controller, a target gateway and the display screen, the target controller being communicatively connected to the display screen through the target gateway.

[0082] As an example, the method 400 comprises the following processes: Figure 4

[0083] S410, obtaining a first target check result of the multimedia host on the first signal.

[0084] As an example, the first signal is used to indicate a signal sent by the target controller to the multimedia host. The first signal comprises a first value (CRC value) and a second value (RC value), and the first target check result is obtained by checking the first signal through the CRC value and the RC value.

[0085] Optionally, taking the target controller as TCU for example, the first signal can be a vehicle gear signal, a vehicle speed signal, etc., and the first signal can be determined according to actual conditions, which is not limited here.

[0086] As an example, the target controller sends the first signal to the multimedia host, the multimedia host checks the first signal to obtain the first target check result, and sends the first target check result to the target controller, so that the target controller obtains the first target check result of the multimedia host on the first signal.

[0087] As an example, the multimedia host obtains the first target check result by checking the first signal; the first signal comprises a CRC value and an RC value, the first check result is obtained by checking the first signal through the CRC value, the second check result is obtained by checking the first signal through the RC value, and the first target check result comprises the first check result and the second check result.

[0088] ​Specifically, the multimedia host determines the first signal by a preset algorithm to obtain a CRC check value of the first signal, and determines whether the CRC value in the first signal is consistent with the CRC check value. When the CRC value is consistent with the CRC check value, it is determined that the check field of the first signal is checked successfully, and the first check result indicates that the check is successful. When the CRC value is inconsistent with the CRC check value, it is determined that the check field of the first signal is checked unsuccessfully, and the first check result indicates that the check is unsuccessful, and the first signal may be tampered with in the transmission process. In addition, the multimedia host determines whether the RC value is consistent with the local RC value (the RC value of the multimedia host side). When the RC value is consistent with the local RC value, it is determined that the count field of the first signal is checked successfully, and the second check result is checked successfully. The second check result is used to indicate the check result of the count field. When the RC value is inconsistent with the local RC value, it is determined that the count field of the first signal is checked unsuccessfully, and the second check result is checked unsuccessfully. Therefore, the communication link may be stuck.

[0089] Further, the multimedia host sends the first target check result to the target controller, and the first target check result includes the first check result and the second check result.

[0090] For example, the first target check result can include that the check field check is successful and the count field check is successful. The first target check result can include that the check field check is successful and the count field check is unsuccessful. The first target check result can also include that the check field check is unsuccessful and the count field check is successful. Of course, the first target check result can also include that the check field check is unsuccessful and the count field check is unsuccessful.

[0091] S420, based on the first target check result, determining a target communication link in the first communication link and the second communication link.

[0092] It should be noted that the first communication link including the target controller in the vehicle and the second communication link of the target controller, the first communication link includes the target controller, the multimedia host and the display screen, and the target controller is connected with the display screen through the multimedia host; the second communication link includes the target controller, the target gateway and the display screen, and the target controller is connected with the display screen through the target gateway. The target controller selects the target communication link from the first communication link and the second communication link through the first target check result.

[0093] It can be understood that the first signal is transmitted to the multimedia host through the first communication link, so that it is determined through the first target check result that the signal transmission is continued through the first communication link or through the second communication link, that is, the target communication link in the first communication link and the second communication link is determined through the first target check result.

[0094] The first target verification result includes a first verification result and a second verification result. The first verification result is used to indicate a verification result of the verification field. The second verification result is used to indicate a verification result of the count field. The target communication link is determined according to the first verification result and the second verification result.

[0095] Specifically, the first verification result can be used to determine whether the first communication link is attacked during the transmission of the first signal, resulting in tampering of the first signal. When the first verification result indicates that the verification of the verification field is successful, it is determined that the first signal is not tampered with. When the first verification result indicates that the verification of the verification field fails, it is determined that the first signal is tampered with. The second verification result can be used to determine whether the first communication link is stuck during the transmission of the first signal. When the second verification result indicates that the verification of the count field is successful, it is determined that the first communication link is not stuck. When the second verification result indicates that the verification of the count field fails, it is determined that the first communication link is stuck.

[0096] For example, when the first verification result indicates that the verification of the verification field is successful, and the second verification result indicates that the verification of the count field is successful, it is determined that the first communication link is the target communication link. When the first verification result indicates that the verification of the verification field is successful, and the second verification result indicates that the verification of the count field fails, it is determined that the first communication link is the target communication link. When the first verification result indicates that the verification of the verification field fails, and the second verification result indicates that the verification of the count field is successful, it is determined that the first communication link is the target communication link. When the first verification result indicates that the verification of the verification field fails, and the second verification result indicates that the verification of the count field fails, it is determined that the second communication link is the target communication link.

[0097] The above technical solution determines the target communication link in the first communication link and the second communication link through the first verification result and the second verification result. Since the first verification result indicates the verification result of the verification field, and the second verification result indicates the verification result of the count field, the security of the first communication link can be determined through the first verification result and the second verification result. Therefore, the target communication link can be determined according to the security and transmission efficiency of the first communication link, and the efficiency of vehicle signal transmission can be ensured.

[0098] In order to further improve the security of signal transmission, when any of the first verification result and the second verification result indicates a verification failure, the second communication link is determined as the target communication link. When both the first verification result and the second verification result indicate a verification success, the first communication link is determined as the target communication link.

[0099] Specifically, if the first check result indicates that the check field check is successful, and the second check result indicates that the count field check is successful, the first communication link is determined as the target communication link; if the first check result indicates that the check field check fails, and / or the second check result indicates that the count field check fails, the second communication link is determined as the target communication link.

[0100] Table 1 is a schematic table of the target communication link.

[0101] First check result Second check result Target communication link Reason causing check failure CRC check success RC check success First communication link CRC check success RC check failure Second communication link First signal transmission jam CRC check failure RC check success Second communication link First signal is attacked CRC check failure RC check failure Second communication link First communication link is severely attacked

[0102] For example, as shown in Table 1, the first check result indicates a CRC check result, the second check result indicates an RC check result, if the CRC check is successful and the RC check is successful, it is determined to continue to transmit signals through the first communication link, and the first communication link is the target communication link; if the CRC check is successful and the RC check fails, during the transmission of the first signal through the first communication link, the first signal transmission may be blocked, and the second communication link is switched to transmit signals, and the second communication link is the target communication link; if the CRC check fails and the RC check is successful, during the transmission of the first signal through the first communication link, the first signal may be attacked, and the second communication link is switched to transmit signals, and the second communication link is the target communication link; if the CRC check fails and the RC check fails, during the transmission of the first signal through the first communication link, the first communication link may be severely attacked, and the second communication link is switched to transmit signals, and the second communication link is the target communication link.

[0103] It can be understood that, since the security of the second communication link is higher than that of the first communication link, signal output through the second communication link can improve the efficiency of signal transmission.

[0104] The above technical solution, if the first check result indicates that the check field check is successful, and the second check result indicates that the count field check is successful, the first communication link is determined as the target communication link, if the first check result indicates that the check field check fails, and / or the second check result indicates that the count field check fails, the second communication link is determined as the target communication link; since the security of the second communication link is higher than that of the first communication link, in the case that any check result of the first check result and the second check result indicates that the check fails, the second communication link is determined as the target communication link, and signal transmission is performed through the second communication link, which can improve the efficiency of signal transmission.

[0105] It should be noted that, in order to avoid waste of irrelevant resources and normal signal transmission, the second communication link is in a dormant state during signal transmission through the first communication link, and the first communication link is interrupted during signal transmission through the second communication link.

[0106] Exemplarily, in a case that the target communication link is the first communication link, the second communication link is controlled to keep in a dormant state; in a case that the target communication link is the second communication link, the second communication link is woken up and the first communication link is interrupted.

[0107] The above technical solution, in a case that the target communication link is the first communication link, the second communication link is controlled to keep in a dormant state, which can avoid irrelevant resource consumption and improve the utilization rate of resources; in a case that the target communication link is the second communication link, the second communication link is woken up and the first communication link is interrupted, which can ensure the normal transmission of signals.

[0108] S430, sending a target signal to the display screen through the target communication link to make the display screen display.

[0109] In one example, the target communication link is the second communication link, and the target signal is sent to the display screen through the target communication link to make the display screen display.

[0110] Exemplarily, the target controller sends a target signal to the target gateway, determines a second target verification result of the target signal through the target gateway, and controls the display screen to display through the second target verification result.

[0111] Exemplarily, in a case that the target controller sends a target signal, the target gateway determines a second target verification result of the target signal based on the target signal, and determines a second signal according to the second target verification result, sends the second signal to the display screen to make the display screen display.

[0112] Exemplarily, the second target verification result is used to indicate the verification result of the verification field, and the second signal is determined through the second target verification result. If the second target verification result indicates that the verification of the verification field is successful, the target signal is converted into the second signal; if the second target verification result indicates that the verification of the verification field fails, a preset signal is determined as the second signal, and the preset signal is used to indicate that the target signal is an invalid signal.

[0113] For example, if the second target verification result indicates that the verification of the verification field is successful, the target signal (CAN signal) is converted into the second signal (I2C signal), and the second signal is displayed through the display screen; if the second target verification result indicates that the verification of the verification field fails, a preset signal is determined as the second signal, and the preset signal is used to indicate that the target signal is an invalid signal. The preset signal displayed on the display screen can be in the form of a black frame; or, the preset signal displayed on the display screen can be warning information, and the warning information is that the signal is invalid, etc.

[0114] For example, the target signal is converted into a second signal through a serial communication protocol (such as an I2C signal), so that the display screen can display it. It is understandable that the target signal cannot be directly displayed by the display screen and needs to be converted into a second signal (such as an I2C signal) that the display screen can display.

[0115] In order to further improve the security of signal transmission, the second target verification result includes a third verification result and a fourth verification result. The third verification result indicates the verification result of the check field; the fourth verification result is used to indicate the verification result of the count field; the second signal is determined by the third verification result and the fourth verification result to control the display screen for display.

[0116] Exemplarily, if the third check result indicates that the check field check is successful, and the fourth check result indicates that the count field check is successful, the target signal is converted into a second signal; if the third check result indicates that the check field check fails, and / or the fourth check result indicates that the count field check fails, the preset signal is determined as the second signal, and the preset signal is used to indicate that the target signal is an invalid signal.

[0117] The above technical solution sends a target signal to the target gateway, determines the second target verification result of the target signal through the target gateway, and controls the display screen to display according to the second target verification result; verifies the target signal through the target gateway and determines the second target verification result, thereby determining the security of the target signal during transmission, and controls the display screen to display according to the second target verification result, which can ensure the accuracy of the information displayed on the display screen.

[0118] Furthermore, when the target communication link is the second communication link, the target signal includes the first signal. It is understood that when the first signal is sent to the multimedia host via the first communication link, if the first target verification result indicates a verification failure (the third verification result indicates a verification failure or the fourth verification result indicates a verification failure), the display screen will not display the information corresponding to the first signal. In this case, the first signal is resent to the target gateway via the target communication link (the second communication link), thereby ensuring that the first signal is not lost, thereby ensuring the integrity of the signal transmission process.

[0119] In the above technical solution, if the target communication link is the second communication link, the target signal includes the first signal. Therefore, if the first signal sent through the first communication link fails to cause the display screen to display, the first signal is resent through the second communication link to avoid signal loss as much as possible, thereby improving the integrity of the signal transmission process.

[0120] In another example, the target communication link is the first communication link, and the target signal is sent to the display screen through the target communication link to cause the display screen to display. Specifically, the target controller sends the target signal to the multimedia host, and in the case that the target signal is verified by the multimedia host, the target signal is converted into an I2C signal, and the display screen is caused to display.

[0121] The above technical solution, the vehicle includes a first communication link of the target controller and a second communication link of the target controller, the first communication link includes the target controller, the multimedia host and the display screen, and the target controller is in communication connection with the display screen through the multimedia host; the second communication link includes the target controller, the target gateway and the display screen, and the target controller is in communication connection with the display screen through the target gateway; by obtaining a first target verification result of the first signal of the multimedia host, based on the first target verification result, the target communication link in the first communication link and the second communication link is determined, and the target signal is sent to the display screen through the target communication link to cause the display screen to display; compared with the prior art in which the target controller only includes the first communication link, the target controller of the present application includes the first communication link and the second communication link, so that in the case that the first target verification result of the first signal transmitted by the first communication link indicates that the verification fails, the second communication link is switched to transmission, which can avoid the vehicle display function abnormal caused by the first target verification result indicating that the verification fails, improve the stability of the vehicle display function, and further improve the driving safety of the vehicle.

[0122] Figure 5 is a schematic flow chart of another vehicle control method provided by the embodiment of the present application.

[0123] Exemplarily, Figure 5 The method shown can be executed by the target gateway in the vehicle. The target gateway is in communication connection with the target controller, and the target gateway is in communication connection with the display screen, so that the target controller is in communication connection with the display screen through the target gateway.

[0124] Exemplarily, as Figure 5 The method 500 includes the following processes:

[0125] S510, if the target signal sent by the target controller is received, a second target verification result of the target signal is determined.

[0126] Exemplarily, the target controller sends a first signal to the multimedia host, and obtains a first target check result of the multimedia host to the first signal. If the first target check result indicates a check failure, it is determined to send a target signal to the display screen through a second communication link, so that the display screen displays. The second communication link is that the target controller connects with the display screen through a target gateway. In a case where the target gateway receives the target signal sent by the target controller, a second target check result of the target signal is determined.

[0127] Optionally, the second target check result of the target signal can refer to a determination manner of the first target check result, which is not described herein again.

[0128] In addition, the target signal includes the first signal. Since the check of the first signal fails in the process of sending the first signal through the first communication link, it is indicated that the first signal is not sent to the display screen. Therefore, the first signal is transmitted again through the second communication link, which can avoid signal loss and improve the efficiency of signal transmission.

[0129] S520, determining a second signal based on the target signal and the second target check result.

[0130] Exemplarily, if the target gateway receives the target signal sent by the target controller, a second target check result of the target signal is determined, and a second signal is determined based on the target signal and the second target check result.

[0131] Exemplarily, the second target check result is used to indicate a check result of a check field. The second signal is determined through the second target check result. If the second target check result indicates that the check field check is successful, the target signal is converted into the second signal. If the second target check result indicates that the check field check fails, a preset signal is determined as the second signal. The preset signal is used to indicate that the target signal is an invalid signal.

[0132] Exemplarily, if the second target check result indicates that the check field check is successful, the target signal (CAN signal) is converted into the second signal (I2C signal), and the display screen displays the second signal. If the second target check result indicates that the check field check fails, a preset signal is determined as the second signal. The preset signal is used to indicate that the target signal is an invalid signal.

[0133] For example, the target signal is converted into the second signal through a serial communication protocol, so that the display screen can display. It can be understood that the target signal cannot be directly displayed by the display screen, and needs to be converted into the second signal (such as I2C signal) which can be displayed by the display screen.

[0134] In order to further improve the security of signal transmission, the second target verification result comprises a third verification result and a fourth verification result, the third verification result indicates a verification result of the verification field, and the fourth verification result is used to indicate a verification result of the count field; and the second signal is determined through the third verification result and the fourth verification result to control the display screen to display.

[0135] For example, if the third verification result indicates that the verification of the verification field is successful, and the fourth verification result indicates that the verification of the count field is successful, the target signal is converted into the second signal; if the third verification result indicates that the verification of the verification field fails, and / or the fourth verification result indicates that the verification of the count field fails, the preset signal is determined as the second signal, and the preset signal is used to indicate that the target signal is an invalid signal.

[0136] The above technical solution, if the second target verification result indicates that the verification of the verification field is successful, the target signal is converted into the second signal, and if the second target verification result indicates that the verification of the verification field fails, the preset signal is determined as the second signal, and the preset signal is used to indicate that the target signal is an invalid signal; on the one hand, in the case that the second target verification result indicates that the verification of the verification field is successful, the accuracy of the display signal can be ensured by converting and displaying the target signal, and on the other hand, in the case that the second target verification result indicates that the verification of the verification field fails, the user can determine that the information transmission is abnormal by displaying the invalid signal, thereby improving the driving safety of the vehicle.

[0137] S530, the second signal is sent to the display screen to make the display screen display.

[0138] For example, the target gateway, in the case that the target signal sent by the target controller is received, determines a second target verification result of the target signal based on the target signal, and determines the second signal according to the second target verification result, and sends the second signal to the display screen to make the display screen display.

[0139] For example, if the second target verification result indicates that the verification of the verification field is successful, the target signal is converted into the second signal, and the second signal is displayed on the display screen; if the second target verification result indicates that the verification of the verification field fails, the preset signal is determined as the second signal, and the preset signal is used to indicate that the target signal is an invalid signal.

[0140] Optionally, the preset signal displayed on the display screen can be in the form of a black frame; or the preset signal displayed on the display screen can be warning information, such as signal invalidity.

[0141] For example, taking the target controller as the TCU, the target signal as the gear signal, in the case that the target gateway successfully checks the gear signal, the gear signal is displayed on the display screen, so that the user can determine the gear information of the current vehicle; in the case that the target gateway fails to check the gear signal, a black frame is displayed on the display screen, so that the user can know that the gear information of the current vehicle is abnormally transmitted and needs to be repaired, thereby the vehicle can be timely repaired to improve the driving safety of the vehicle.

[0142] The technical solution, the target controller is connected with the display screen through the target gateway, if the target gateway receives the target signal sent by the target controller, determines the second target check result of the target signal, and determines the second signal based on the target signal and the second target check result, and sends the second signal to the display screen to make the display screen display; the target gateway determines the second signal through the second target check result and the target signal, which can ensure the accuracy of the second signal, and on this basis, the second signal is sent to the display screen, which can ensure the accuracy of the display signal displayed by the display screen, thereby improving the driving safety of the vehicle.
