[0002] As vehicles become increasingly intelligent, the number of vehicle control units (ECUs) is growing, and the information exchange between these ECUs is becoming more frequent and complex. Implementing specific functions, such as Bluetooth key unlocking, involves the coordinated work of multiple ECUs. A software freeze in any one ECU can cause the entire function to malfunction, potentially leading to problems such as inability to unlock or start the car.

Detailed Implementation

[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0045] In existing technologies, if a vehicle cannot be unlocked or started, roadside assistance or a tow truck is typically called to transport the disabled vehicle to a repair shop. However, these existing methods severely impact the user experience and control efficiency.

[0046] This application obtains vehicle status information in response to a restart trigger signal sent by a restart switch module. If the status information meets preset restart conditions, a first restart notification signal is sent to each vehicle controller. After a first preset time after sending the first restart notification signal, the power supply line is disconnected. After a second preset time after the power supply line is disconnected, the power supply line is reconnected to enable the vehicle controller to restart. By controlling the connection and disconnection of the power supply line between the low-voltage battery and at least one vehicle controller in response to the restart trigger signal, the vehicle controller can be restarted promptly when restarting is required, thereby improving the restart efficiency and user experience. Furthermore, determining whether the vehicle status information meets the preset restart conditions before controlling the connection and disconnection of the power supply line between the low-voltage battery and at least one vehicle controller improves the safety of the vehicle controller restart. In summary, this application can improve the restart efficiency, user experience, and safety of the vehicle controller.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0048] Figure 1 Flowchart of the vehicle controller restart method provided in this application Figure 1 The execution entity is the low-voltage battery-powered control module or the vehicle controller's restart device. Generally, this can be implemented through software, hardware, or a combination of both. Figure 1 As shown, the method includes:

[0049] Step S101: In response to the restart trigger signal sent by the restart switch module, obtain the vehicle status information.

[0050] The low-voltage battery power supply control module is used to control the on / off state of the power supply line between the low-voltage battery and at least one vehicle controller. This application does not limit the power supply circuit between the low-voltage battery and the vehicle controller; any circuit that enables the low-voltage battery to supply power to the vehicle controller and whose on / off state can be controlled by the low-voltage battery power supply control module can be used as the power supply circuit provided in this application. Optionally, the power supply circuit between the low-voltage battery and at least one vehicle controller provided in this application can be a circuit with a relay connected to it. Optionally, if the power supply circuit between the low-voltage battery and at least one vehicle controller provided in this application can be a circuit with a relay connected to it, then the low-voltage battery power supply control module can control the on / off state of the power supply line between the low-voltage battery and at least one vehicle controller by controlling the opening and closing of the relay connected to the power supply circuit. Specifically, if the low-voltage battery power supply control module controls the relay to close, it controls the connection of the power supply line between the low-voltage battery and at least one vehicle controller; if the low-voltage battery power supply control module controls the relay to open, it controls the disconnection of the power supply line between the low-voltage battery and at least one vehicle controller.

[0051] Specifically, in response to the restart trigger signal sent by the restart switch module, the vehicle's status information can be obtained. The restart switch module is a device that generates and sends the restart trigger signal. This restart trigger signal is used to trigger the vehicle controller's restart function.

[0052] Herein, status information refers to information that characterizes the state of the vehicle. Specifically, this application does not limit the type of information included in the status information. Any information that can characterize the state of the vehicle can be used as the status information provided in this application. Optionally, the status information includes, but is not limited to, information such as the vehicle's gear status, vehicle speed status, vehicle operating mode status, and power supply status of the vehicle's controller.

[0053] This application does not limit the process for obtaining vehicle status information; any process capable of obtaining vehicle status information can be used as the process for obtaining vehicle status information provided in this application. Optionally, vehicle status information can be obtained from at least one of at least one vehicle controller, and / or from a vehicle server.

[0054] Step S102: If the status information meets the preset restart conditions, a first restart notification signal is sent to each vehicle controller.

[0055] Specifically, if the vehicle status information obtained in step S101 meets the preset restart conditions, a first restart notification signal is sent to each vehicle controller.

[0056] The preset restart conditions are pre-defined conditions used to determine whether each vehicle controller can be restarted based on the vehicle's status information. This application does not limit the preset restart conditions; any pre-defined condition used to determine whether each vehicle controller can be restarted based on the vehicle's status information can be used as the preset restart conditions provided in this application. These preset restart conditions are used to ensure vehicle safety during vehicle controller restart; that is, if the vehicle's status information meets the preset restart conditions, it is determined that the vehicle is safe during the vehicle controller restart.

[0057] The first restart notification signal is a signal that notifies each vehicle controller to restart. This application does not limit the first restart notification signal; any signal that can notify each vehicle controller to restart can be used as the first restart notification signal provided in this application.

[0058] Optionally, if the status information does not meet the preset restart conditions, a prompt message indicating that the preset restart conditions are not met can be generated and presented to the user. This application does not limit the method of presenting the prompt message indicating that the preset restart conditions are not met. Optionally, the prompt message can be presented via voice broadcast; optionally, the prompt message can be presented on the display interface of the client terminal; optionally, the prompt message can be presented on the display interface of the vehicle's central control system. Optionally, the prompt message indicating that the preset restart conditions are not met may include the vehicle's status information that caused the status information to fail to meet the preset restart conditions.

[0059] Step S103: After a first preset time after sending the first restart notification signal, the control power supply line is disconnected; and after a second preset time after the control power supply line is disconnected, the control power supply line is reconnected so that the vehicle controller can complete the restart.

[0060] The first preset duration is a preset duration used to ensure that each vehicle controller has received the first restart notification signal. This application does not limit the first preset duration; any preset duration that can ensure that each vehicle controller has received the first restart notification signal can be used as the first preset duration provided in this application. Optionally, the first preset duration can be 3 seconds.

[0061] Specifically, after a first preset time period following the sending of the first restart notification signal to each vehicle controller, i.e., after ensuring that each vehicle controller has received the first restart notification signal, the power supply line can be disconnected. This application does not limit the process of disconnecting the power supply line; optionally, if the power supply circuit is described as in step S101, the process of disconnecting the power supply line can involve opening the relays connected in the power supply circuit.

[0062] The second preset duration is a preset duration to ensure that each vehicle controller has completed the power-off process. This application does not limit the second preset duration; any preset duration that can ensure that each vehicle controller has completed the power-off process can be used as the second preset duration provided in this application. Optionally, the second preset duration can be 2 seconds.

[0063] Specifically, after a second preset time period following the disconnection of the control power supply line, i.e., after ensuring that each vehicle controller has been powered off, the control power supply line can be connected to enable the vehicle controller to restart. This application does not limit the process of connecting the control power supply line. Optionally, if the power supply circuit is described as in step S101, the process of connecting the control power supply line can involve closing the relays connected in the control power supply circuit.

[0064] The vehicle controller restart method provided in this application obtains vehicle status information in response to a restart trigger signal sent by a restart switch module. If the status information meets preset restart conditions, a first restart notification signal is sent to each vehicle controller. After a first preset time after sending the first restart notification signal, the power supply line is disconnected. After a second preset time after the power supply line is disconnected, the power supply line is reconnected to enable the vehicle controller to restart. By controlling the connection and disconnection of the power supply line between the low-voltage battery and at least one vehicle controller in response to the restart trigger signal, the vehicle controller can be restarted in a timely manner when restarting is required, thereby improving the restart efficiency and user experience. Before controlling the connection and disconnection of the power supply line between the low-voltage battery and at least one vehicle controller, it is determined whether the vehicle status information meets the preset restart conditions, which can improve the restart safety of the vehicle controller. In summary, this application can improve the restart efficiency, user experience, and safety of the vehicle controller.

[0065] Figure 2 Flowchart of the vehicle controller restart method provided in this application Figure 2 In this embodiment Figure 1 Based on the embodiments, if the vehicle's high-voltage battery supplies power to at least one vehicle controller via a high-voltage battery power supply control module, a detailed description of a method for restarting another vehicle controller is provided, the method including:

[0066] Step S201: In response to the restart trigger signal sent by the restart switch module, obtain the vehicle status information.

[0067] For a detailed description of this step, please refer to the description in step S101, which will not be repeated here.

[0068] Step S202: If the status information meets the preset restart conditions, a first restart notification signal is sent to each vehicle controller.

[0069] For a detailed description of this step, please refer to step S102, which will not be repeated here.

[0070] The description of the first restart notification signal can be found in step S102, and will not be repeated here.

[0071] Optionally, based on the description in step S102, the first restart notification signal is used to instruct the vehicle controller to perform a restart preprocessing operation.

[0072] Specifically, the vehicle controller performs a pre-restart processing operation to ensure that each vehicle controller can resume normal operation after restarting. This application does not limit the pre-restart processing operation; any processing operation capable of restoring the normal operation of each vehicle controller can be used as the pre-restart processing operation performed by the vehicle controller indicated by the first restart notification signal provided in this application. Optionally, this can include processing operations such as storing current control parameters. The stored current control parameters differ depending on the type of vehicle controller. For example, if the vehicle controller is a vehicle seat controller, it can store parameters such as the current seat position; if the vehicle controller is a vehicle window controller, it can store parameters such as the current window position.

[0073] If the first restart notification signal is also used to instruct the vehicle controller to perform pre-restart processing operations, it can ensure that each vehicle controller can resume normal operation after restarting, thereby improving the safety of vehicle controller restart and user experience.

[0074] Optionally, based on the description in step S102, the preset restart conditions may include: the vehicle where the vehicle controller is located is in P gear, the vehicle speed of the vehicle where the vehicle controller is located is lower than a preset speed, the vehicle where the vehicle controller is located is not in driving mode, and the vehicle controller is powered by a low-voltage battery. The preset restart conditions, including the vehicle controller being in P gear, the vehicle speed being lower than the preset speed, and the vehicle controller not being in driving mode, ensure vehicle safety before the vehicle controller restarts. The fact that the vehicle controller is powered by a low-voltage battery in the preset restart conditions ensures that the vehicle controller restart method provided in this application can be executed.

[0075] If the preset restart conditions are as described above, the vehicle's status information may include the vehicle's gear status information, vehicle speed status information, vehicle operating mode status information, and the power supply status information of the vehicle's controller.

[0076] Specifically, if all the following conditions are met in the status information: the vehicle's gear status information is in P gear; the vehicle's speed status information is lower than a preset speed; the vehicle's operating mode status information is not in driving mode; and the vehicle controller's power supply status information is powered by a low-voltage battery, then the status information satisfies the preset restart conditions. Conversely, if at least one of the above conditions is not met, the status information does not satisfy the preset restart conditions.

[0077] By pre-setting restart conditions, it can be ensured that the vehicle controller is in a safe state before restarting, thereby improving the safety of restarting the vehicle controller.

[0078] Step S203: Send a second restart notification signal to the high-voltage battery power supply control module. The second restart notification signal is used to instruct the high-voltage battery power supply control module to stop supplying power to the vehicle controller. The second restart notification signal is also used to instruct the high-voltage battery power supply control module to start timing after receiving the second restart notification signal, and to stop supplying power to the vehicle controller when the timing reaches a first preset duration. The second restart notification signal is also used to instruct the high-voltage battery power supply control module to resume supplying power to the vehicle controller after a second preset duration after stopping supplying power to the vehicle controller, so that the vehicle controller can complete the restart.

[0079] Specifically, if the vehicle's high-voltage battery supplies power to at least one vehicle controller via the high-voltage battery power supply control module, the restart process for the vehicle controller also includes sending a second restart notification signal to the high-voltage battery power supply control module.

[0080] The second restart notification signal is used to instruct the high-voltage battery power supply control module to stop supplying power to the vehicle controller. This application does not limit the second restart signal; any signal capable of instructing the high-voltage battery power supply control module to stop supplying power to the vehicle controller can be used as the second restart notification signal provided in this application.

[0081] In this application, the timing of sending the second restart notification signal to the high-voltage battery power supply control module is not limited. Optionally, the second restart notification signal can be sent to the high-voltage battery power supply control module at the same time as determining that the status information meets the preset restart conditions, that is, at the same time as sending the first restart notification signal described above.

[0082] In this configuration, if the vehicle's high-voltage battery supplies power to at least one vehicle controller via the high-voltage battery power supply control module, the vehicle controller cannot be restarted unless the high-voltage battery power supply control module is instructed to stop supplying power to the vehicle controller during the vehicle controller restart process, thus improving the accuracy of the vehicle controller restart.

[0083] Optionally, based on the above description, the second restart notification signal is also used to instruct the high-voltage battery power supply control module to start timing after receiving the second restart notification signal, and to stop supplying power to the vehicle controller when the timing duration reaches the first preset duration.

[0084] The description of the first preset duration can be found in step S103, and will not be repeated here.

[0085] Specifically, after a first preset time period following the sending of the second restart notification signal to the high-voltage battery power supply control module, i.e., after ensuring that each vehicle controller has received the first restart notification signal, the high-voltage battery can be controlled to stop supplying power to the vehicle controller. This application does not limit the process of controlling the high-voltage battery to stop supplying power to the vehicle controller after the first preset time period following the sending of the second restart notification signal to the high-voltage battery power supply control module, i.e., after ensuring that each vehicle controller has received the first restart notification signal. Optionally, the second restart notification signal can also be used to instruct the high-voltage battery power supply control module to start timing after receiving the second restart notification signal, and to stop supplying power to the vehicle controller when the timing reaches the first preset time period.

[0086] Optionally, the second restart notification signal is also used to instruct the high-voltage battery power supply control module to re-supply the vehicle controller after a second preset time period following the cessation of power supply to the vehicle controller, so that the vehicle controller can complete the restart.

[0087] The description of the second preset duration can be found in step S103, and will not be repeated here.

[0088] Specifically, after a second preset time period following the cessation of power supply to the vehicle controllers—that is, after ensuring that all vehicle controllers have been de-energized—the high-voltage battery power supply control module can re-supply the vehicle controllers to enable them to restart. This application does not limit the process of re-supplying the vehicle controllers; optionally, the second restart notification signal can also be used to instruct the high-voltage battery power supply control module to re-supply the vehicle controllers after the second preset time period following the cessation of power supply to them, thereby enabling them to restart.

[0089] Step S204: After a first preset time following the sending of the first restart notification signal, the control power supply line is disconnected; and after a second preset time following the disconnection of the control power supply line, the control power supply line is reconnected so that the vehicle controller can complete the restart.

[0090] For a detailed description of this step, please refer to step S103, which will not be repeated here.

[0091] Another method for restarting a vehicle controller provided in this application embodiment, in Figure 1 Based on the illustrated embodiment, if the vehicle's high-voltage battery supplies power to at least one vehicle controller through the high-voltage battery power supply control module, and the high-voltage battery power supply control module is controlled by the second restart control signal, the restart efficiency, user experience, and safety of the vehicle controller can be improved.

[0093] The restart switch module 303 is connected to the low-voltage battery power supply control module 301 and is used to generate and send a restart trigger signal to the low-voltage battery power supply control module 301 in response to the user's trigger operation.

[0094] The restart switch module 303 is a preset switch module for triggering the restart of the vehicle controller 304. This application does not limit the restart switch module 303; any preset switch module for triggering the restart of the vehicle controller 304 can be used as the restart switch module 303 provided in this application. Optionally, the restart switch module 303 can be an existing switch in the vehicle where the vehicle controller 304 is located, and / or at least one of the following: a dedicated switch installed on the vehicle where the vehicle controller 304 is located.

[0095] This application does not limit the user's triggering operation; any operation that can trigger the restart of the vehicle controller 304 can be used as the user's triggering operation provided in this application. Different user triggering operations can be preset for different restart switch modules 303. Optionally, the user triggering operation can be at least one of the following: pressing and holding for a preset duration, clicking a preset number of times, or clicking each switch in the restart switch module 303 according to a preset clicking order.

[0096] The description of the restart trigger signal can be found in step S101, and will not be repeated here.

[0097] The low-voltage battery power supply control module 301 is connected to the low-voltage battery 302 and each of the multiple vehicle controllers 304. It is used to acquire vehicle status information in response to a restart trigger signal sent by the restart switch module 303. If the status information meets preset restart conditions, a first restart notification signal is sent to each vehicle controller 304. After a first preset time period following the sending of the first restart notification signal, the control power supply line is disconnected. After a second preset time period following the disconnection of the control power supply line, the control power supply line is reconnected to enable the vehicle controller 304 to complete the restart.

[0100] The description of the power supply circuit between the low-voltage battery 302 and each vehicle controller 304 can be found in step S101, and will not be repeated here.

[0101] The vehicle controller 304 restart system provided in this application embodiment generates and sends a restart trigger signal to the low-voltage battery power supply control module in response to the user's trigger operation, thereby controlling the low-voltage battery power supply control module to restart the vehicle controller. This can improve the restart efficiency, user experience, and safety of the vehicle controller.

[0105] The low-voltage battery power supply control module 301 is connected to the low-voltage battery 302 and each of the multiple vehicle controllers 304. It is used to acquire vehicle status information in response to a restart trigger signal sent by the restart switch module 303. If the status information meets preset restart conditions, a first restart notification signal is sent to each vehicle controller 304. After a first preset time period following the sending of the first restart notification signal, the control power supply line is disconnected. After a second preset time period following the disconnection of the control power supply line, the control power supply line is reconnected to enable the vehicle controller 304 to complete the restart.

[0106] The low-voltage battery 302 is connected to each of the multiple vehicle controllers 304 via a power supply circuit, and is used to supply power to the corresponding vehicle controller 304 when the power supply circuit is connected.

[0107] The description of the above content can be found in the following references. Figure 3 The descriptions in the illustrated embodiments will not be repeated here.

[0108] Optionally, in Figure 3 Based on the embodiment shown, the vehicle controller 304 is also configured to perform pre-restart processing operations in response to the first restart signal.

[0109] The process of receiving the first restart signal and performing pre-restart processing can be referred to in step S202, and will not be repeated here.

[0110] The vehicle controller 304, in response to the first restart signal, performs pre-restart processing operations, which ensures that each vehicle controller 304 can resume normal operation after restarting, thereby improving the safety of restarting the vehicle controller 304 and the user experience.

[0111] Optionally, the restart system of the vehicle controller 304 further includes a high-voltage battery 305 and a high-voltage battery power supply control module 306. The high-voltage battery power supply control module 306 is connected to the high-voltage battery 305 and is connected to each of the multiple vehicle controllers 304 via a power supply circuit.

[0112] High-voltage battery 305 is used to power at least one vehicle controller 304 via high-voltage battery power supply control module 306.

[0113] The high-voltage battery power supply control module 306 is used to convert the high-voltage signal provided by the high-voltage battery 305 into a low-voltage signal and supply power to the vehicle controller 304 through the power supply circuit.

[0114] The high-voltage battery power supply control module 306 is also connected to the low-voltage battery power supply control module 301.

[0115] The low-voltage battery power supply control module 301 is also used to send a second restart notification signal to the high-voltage battery power supply control module 306.

[0116] The high-voltage battery power supply control module 306 is also used to stop supplying power to the vehicle controller 304 in response to a second restart notification signal.

[0117] For a description of the second restart notification signal, please refer to [reference needed]. Figure 2 The descriptions in the illustrated embodiments will not be repeated here.

[0118] Among them, Figure 3 Based on the embodiment shown, by setting up a high-voltage battery 305 and a high-voltage battery power supply module, and stopping the power supply to the vehicle controller 304 through a second restart notification signal, the restart process of the vehicle controller 304 is completed, thereby improving the accuracy of the restart of the vehicle controller 304.

[0119] Optionally, the high-voltage battery power supply control module 306 is further configured to obtain a restart rule from the second restart notification signal and stop or resume power supply to the vehicle controller 304 according to the restart rule. The restart rule includes starting a timer after receiving the second restart notification signal, stopping power supply to the vehicle controller 304 when the timer reaches a first preset duration, and resuming power supply to the vehicle controller 304 after a second preset duration following the cessation of power supply, so that the vehicle controller 304 completes a restart.

[0120] Referring to the description in step S203, in order to enable the vehicle controller 304 to complete the restart, a restart rule can be set in the second restart notification signal, so that the high-voltage battery power supply control module 306 stops or resumes power supply to the vehicle controller 304 according to the restart rule, thereby improving the accuracy of the restart of the vehicle controller 304.

[0121] Optionally, the high-voltage battery power supply control module 306 is further configured to, in response to the second restart notification signal, stop or resume power supply to the vehicle controller 304 according to pre-stored restart rules. The pre-stored restart rules include stopping power supply to the vehicle controller 304 for a first preset duration after receiving the second restart notification signal, and resuming power supply to the vehicle controller 304 for a second preset duration after stopping power supply to the vehicle controller 304.

[0122] Referring to the description in step S203, in order to enable the vehicle controller 304 to complete the restart, the restart rules can be pre-stored in the high-voltage battery power supply control module 306. The high-voltage battery power supply control module 306 can then stop or resume power supply to the vehicle controller 304 according to the restart rules, thereby improving the accuracy of the vehicle controller 304's restart.

[0123] Optionally, the vehicle controller 304 includes a door lock controller. Specifically, if the vehicle controller 304 includes a door lock controller, the door lock controller can be restarted through the vehicle controller 304 restart system provided in this application when the door cannot be opened due to a malfunction of the vehicle controller 304, thereby improving the restart efficiency of the vehicle controller 304 and the user experience.

[0124] Optionally, the restart switch module 303 is located on the exterior of the vehicle.

[0125] Specifically, as described above, if the door cannot be opened due to a malfunction of the door lock controller included in the vehicle controller 304, and if the restart switch module 303 is located inside the vehicle while the user is outside the vehicle, the restart process of the vehicle controller 304 provided in this application cannot be executed. Therefore, the restart switch module 303 can be located outside the vehicle to ensure the restart of the vehicle controller 304, thereby further improving the efficiency of the restart of the vehicle controller 304 and the user experience.

[0126] The vehicle controller restart system provided in this application embodiment, in Figure 3 Based on the system shown, by setting up a high-voltage battery and a high-voltage battery power supply control module, and stopping the power supply to the vehicle controller through a second restart notification signal, the restart process of the vehicle controller is completed, thereby improving the accuracy of the vehicle controller restart.
