To facilitate the understanding of the embodiments of the present application, the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] In order to solve the technical problem in the prior art that the vehicle gear cannot be accurately restored after the controller is reset, the present application provides a gear control method after the vehicle controller is started, which can effectively reduce the risk caused by the gear cannot be restored after the controller is started.

[0038] Figure 1A flow chart of a method for controlling the gear position after a vehicle controller is started is provided for an embodiment of the present application. This method can be applied to a vehicle and executed by a controller on the vehicle. Optionally, this method can also be executed by other electronic devices connected to the vehicle in communication, such as one or more electronic devices such as a server, a smart phone, a laptop computer, a desktop computer, etc. These electronic devices can monitor the operation of the controller on the vehicle in real time, and when the target controller is started, execute this method to determine the gear position information of the vehicle and feed the gear position information back to the vehicle. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0039] like Figure 1 As shown, the method specifically includes:

[0040] Step 101 , in response to a target controller of a vehicle executing a start-up operation, read backup gear information from a preset gear backup storage area.

[0041] In this embodiment, the target controller may be a controller on the vehicle for controlling the gear position, such as a vehicle controller. The startup operation may be a restart of the target controller, and a series of startup process operations such as executing software and hardware initialization. The startup operation may be triggered by any of the following operations: the target controller is powered on again according to the preset power-on and power-off process, and the target controller is abnormally reset. Among them, powering on again according to the preset power-on and power-off process refers to the process of the vehicle being powered on again after performing a normal shutdown operation through a key switch, remote control, etc. Abnormal reset refers to the operation performed by the controller to re-execute the startup process due to loose wiring harness, abnormal power supply, etc.

[0042] The gear backup storage area may be a storage area pre-set in the target controller for storing gear information. For example, a protected area may be set in the RAM (Random Access Memory) of the target controller, which can only be used to store gear related information.

[0043] In this embodiment, the backup gear information stored in the gear backup storage area is different for startup operations caused by different reasons.

[0044] Step 102, verify the backup gear information to obtain a real-time verification code.

[0045] In this embodiment, the backup gear information may be verified according to a preset verification algorithm, which may be various types of verification algorithms, such as a CRC (Cyclic Redundancy Check) verification algorithm.

[0046] Step 103, reading a pre-stored backup verification code from the gear backup storage area.

[0047] In this embodiment, the backup verification code is a verification code obtained by pre-verifying the gear information stored at the gear backup time. The gear backup time is a preset time for recording the gear of the vehicle. For example, during the normal use of the vehicle, the gear of the vehicle can be recorded in real time according to the preset backup cycle, and the backup verification code is generated according to the recorded gear information and the above-mentioned preset verification algorithm.

[0048] Step 104 : If the real-time verification code and the backup verification code are consistent, it is determined that the startup operation is performed due to an abnormality in the target controller, and the gear of the vehicle is set based on the backup gear information.

[0049] In this embodiment, when an abnormal situation occurs in the target controller and causes a reset, the data stored in the gear backup storage area will not change, that is, the backup gear information in the gear backup storage area remains unchanged. At this time, the real-time verification code and the backup verification code are consistent, and the gear of the vehicle can be restored to the gear before the abnormality occurs based on the backup gear information.

[0050] Step 105 , if the real-time verification code and the backup verification code are inconsistent, it is determined that the startup operation is performed when the target controller is powered on normally, and the gear position of the vehicle is set to a preset gear position.

[0051] In this embodiment, if the target controller is powered on again after a normal shutdown operation, the data stored in the gear backup storage area will change, that is, the backup gear information in the gear backup storage area will change. At this time, the real-time verification code and the backup verification code are inconsistent, and the vehicle's gear can be set to a preset gear, such as neutral (N gear).

[0052] The gear control method after the vehicle controller is started provided in the embodiment of the present application is to read the backup gear information from the gear backup storage area when the target controller of the vehicle performs the startup operation, verify the backup gear information, obtain the real-time verification code, and then read the backup verification code from the gear backup storage area, compare the real-time verification code and the backup verification code, and set the gear of the vehicle based on the comparison result. The embodiment of the present application realizes the storage of backup gear information in the gear backup storage area, and utilizes the different characteristics of the backup gear information in the backup storage area after resetting in the two situations of normal power on and off and abnormal reset to restore the gear of the vehicle, improve the matching of the vehicle gear with the actual driving scene, and reduce the driving safety risk caused by the inability to restore the gear after the abnormal reset of the vehicle controller.

[0053] In some optional implementations of this embodiment, the backup storage area is set in the random access memory of the target controller, and the backup storage area is a storage area that has been protected in advance.

[0054] The above-mentioned protection processing refers to setting up a protection program so that the backup storage area can only store information related to the gear position, and other applications are prohibited from reading and writing to the storage area. Usually, in order to store data stably and avoid accidental erasure, non-volatile memory is often used for storage. Non-volatile memory includes ROM (Read-only memory), EPROM (Electrically alterable read only memory), Flash memory, etc. When writing data to a non-volatile memory, there is a risk of write failure. The present embodiment uses a random access memory (RAM), and sets a protected area in the random access memory for storing backup gear information, which can avoid data write failure and thereby improve the reliability of gear backup.

[0055] In some optional implementations of this embodiment, such as Figure 2 As shown, after step 105, the method further includes:

[0056] Step 106 , in response to the start-up operation being completed, adjusting the gear of the vehicle based on the gear currently selected by the user.

[0057] That is, when it is determined that the startup operation is executed when the target controller is powered on normally, the vehicle's gear is first set to a preset gear (such as neutral), and then it is determined whether the user has selected other gears (such as parking). If other gears are selected, the gear can be set to the gear selected by the user.

[0058] This embodiment sets the gear based on the user's current selection when the target controller is powered on normally and performs the startup operation, thereby achieving timely response to the user's gear selection operation after resetting, thereby improving the scenario adaptability of the vehicle gear switching.

[0059] In some optional implementations of this embodiment, such as Figure 3 As shown, before step 101, the method further includes:

[0060] Step 107 , in response to triggering a normal shutdown operation of the target controller, adjusting the backup gear information in the gear backup storage area to a preset value.

[0061] The normal shutdown operation refers to the operation of controlling the target controller to stop running according to the normal shutdown process after the user stops driving the vehicle. For example, the operation of turning off the target controller by key switch or remote control switch light is a normal shutdown operation. The above preset value can be any value, such as zero value, that is, when the target controller is normally shut down, the reset procedure is executed to reset the gear information stored in the gear backup storage area.

[0062] After the subsequent execution of steps 101-103, since the backup gear information has changed, the real-time verification code and the backup verification code will be inconsistent, that is, step 105 is executed to determine that the startup operation is performed when the target controller is powered on normally, and the gear of the vehicle is set to the preset gear.

[0063] Step 108 , in response to triggering the abnormal shutdown operation of the target controller, keeping the backup gear information in the gear backup storage area unchanged.

[0064] Among them, the abnormal shutdown operation may be caused by loose wiring harness of the target controller, abnormal power supply, etc. After the abnormal shutdown operation is triggered, the target controller will automatically restart, that is, an abnormal reset occurs. At this time, the gear information stored in the gear backup storage area remains unchanged.

[0065] After the subsequent execution of steps 101-103, since the backup gear information has not changed, the real-time verification code and the backup verification code are consistent, that is, step 104 is executed to determine that the startup operation is performed due to an abnormal situation in the target controller, and the gear of the vehicle is set based on the backup gear information.

[0066] In this embodiment, when the target controller is normally shut down, the data in the gear backup storage area is reset. When it is abnormally shut down, the data in the gear backup storage area is kept unchanged, thereby accurately determining the reason why the target controller performs the startup operation and accurately setting the gear of the vehicle.

[0067] In some optional implementations of this embodiment, the number of backed-up gear information is at least two. That is, when backing up the gear information, at least two gear information are backed up. For example, three gear information are backed up each time.

[0068] like Figure 4 As shown, step 102 includes:

[0069] Step 1021, merge at least two backup gear information to obtain merged gear information.

[0070] When at least two backup gear information are merged, they can be connected into one piece of gear information as merged gear information.

[0071] Step 1022, verify the merged gear information to obtain a real-time verification code.

[0072] This embodiment can complicate the data used when executing the verification algorithm by backing up at least two pieces of gear information, and the generated verification code can more accurately represent the backed-up gear.

[0073] In some optional implementations of this embodiment, such as Figure 5 As shown, after step 104 or step 105, the method further includes:

[0074] Step 109, according to the preset gear backup cycle, the current gear information of the vehicle is stored in the gear backup storage area at regular intervals.

[0075] The gear backup period can be set arbitrarily, for example, the gear backup period is 1 second, that is, the gear backup operation is performed once per second.

[0076] Step 110, verify the gear information currently stored in the gear backup storage area to obtain the verification code to be stored, and replace the backup verification code in the gear backup storage area with the verification code to be stored.

[0077] Optionally, when backing up the gear information, you can follow the above Figure 4 The method corresponding to the embodiment shown in the figure backs up at least one gear information, and when calculating the backup check code, it can be performed according to Figure 4 The same method as the embodiment shown is used to combine multiple gear information and then calculate the check code.

[0078] This embodiment backs up the vehicle's gear information and verification code in real time during normal vehicle operation, so that when a startup operation occurs again, the most recently backed-up gear information and verification code can be obtained from the gear backup storage area, thereby facilitating accurate gear restoration.

[0079] In some optional implementations of this embodiment, such as Figure 6As shown, step 101 includes:

[0080] Step 1011 , in response to a power-on signal or a reset signal that triggers the target controller, start executing a startup operation of the target controller.

[0081] The power-on signal is a signal generated when the target controller is normally powered on, and the reset signal is a signal generated when the target controller is abnormally reset.

[0082] Step 1012, executing the initialization program included in the startup operation, and in response to executing the upper electronic program included in the initialization program, reading the backup gear information from the preset gear backup storage area.

[0083] Among them, the initialization program is used to initialize the software and hardware of the target controller. The initialization program usually includes a base layer initialization program and an application layer initialization program. The base layer initialization mainly includes hardware-related initialization, including sensor data acquisition, CAN (Controller Area Network) controller driver, input / output access, memory control, etc. After the base layer initialization is completed, the application layer initialization and electronic program are entered.

[0084] The application layer initialization program mainly includes the initialization and verification of some key variables in the application layer functional strategy, among which the reading and verification of the gear information can be performed through the upper electronic program included in the application layer initialization program.

[0085] This embodiment sets up an electronic program to achieve that each time a startup operation is performed, the backup gear information is first read from the gear backup storage area and verified through initialization. Therefore, when the target controller is started, the backup gear information can be judged in time and the gear can be restored in time, thereby improving the efficiency of gear recovery.

[0089] The second reading module 703 is used to read the pre-stored backup verification code from the gear backup storage area, wherein the backup verification code is a verification code obtained by pre-verifying the gear information stored at the gear backup time;

[0090] The first determination module 704 is used to determine that the startup operation is performed due to an abnormal situation of the target controller if the real-time verification code and the backup verification code are consistent, and set the gear of the vehicle based on the backup gear information, wherein when the startup operation is performed due to an abnormal situation of the target controller, the backup gear information in the gear backup storage area remains unchanged;

[0091] The second determination module 705 is used to determine that the startup operation is performed when the target controller is powered on normally if the real-time verification code and the backup verification code are inconsistent, and set the gear position of the vehicle to a preset gear position. When the target controller is powered on normally to perform the startup operation, the backup gear position information in the gear backup storage area changes.

[0092] In a possible implementation manner, the backup storage area is set in a random access memory of the target controller, and the backup storage area is a storage area that has been protected in advance.

[0095] In a possible implementation, the number of backup gear information is at least two; the verification module includes: a merging unit, used to merge at least two backup gear information to obtain merged gear information; a verification unit, used to verify the merged gear information to obtain a real-time verification code.
