Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a vehicle gear control method, device and vehicle in the field of vehicle technology. Background Art

[0002] As autonomous driving technology matures, more and more vehicles are beginning to use electronic shifters in their braking systems. Electronic shifters are generally available in a variety of forms, including lever, knob, button, dial, and hand-held shifters. Their main function is to receive the driver's shift operation and output the gear position signal corresponding to the driver's shift operation to the vehicle controller through logical control, so that the vehicle controller controls the transmission to perform the corresponding shift operation according to the gear position signal.

[0003] However, the electronic shifter is prone to malfunction during use, causing the vehicle to enter limp home mode, limiting the vehicle's shifting function and causing the vehicle to be unable to meet the driver's shifting needs. Summary of the invention

[0004] The present application provides a vehicle gear control method, device and vehicle, which can meet the driver's gear shifting needs when the vehicle enters a limp home mode due to a failure of an electronic gear shifter.

[0005] In a first aspect, a vehicle gear control method is provided, the method comprising: when the vehicle enters a limp mode due to a failure of an electronic shifter, activating a backup shifter, the limp mode being a vehicle mode in which the vehicle's shifting function is restricted; when the backup shifter is activated, lifting the restriction on the vehicle's shifting function; and controlling the vehicle to shift gears based on the backup shifter.

[0006] In the above technical scheme, an embodiment of the present application provides a vehicle gear control method: when the vehicle enters a limp mode (a vehicle mode in which the vehicle's gear shifting function is restricted) due to a failure of an electronic gear shifter, the backup gear shifter can be activated, thereby releasing the restriction on the vehicle's gear shifting function when the backup gear shifter is activated, and then based on the backup gear shifter, the vehicle is controlled to shift gears, thereby meeting the driver's gear shifting needs and avoiding the situation where the vehicle cannot meet the driver's gear shifting needs when the vehicle enters a limp mode due to a failure of an electronic gear shifter.

[0007] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the backup shifter is the vehicle's turn signal switch; based on the backup shifter, the vehicle is controlled to shift gears, including: obtaining the current target position of the vehicle's turn signal switch; determining the vehicle's gear signal corresponding to the target position; and based on the gear signal, controlling the vehicle to shift gears.

[0008] In the above technical scheme, in one possible implementation manner, the target position of the vehicle's turn signal switch can be corresponded to the vehicle's gear signal, so that when the backup shifter is the vehicle's turn signal switch, the vehicle's gear signal can be determined by obtaining the current target position of the vehicle's turn signal switch, thereby controlling the vehicle to shift gears based on the gear signal, thereby ensuring that the vehicle meets the driver's gear shifting requirements without changing the vehicle's hardware.

[0009] In combination with the first aspect and the above-mentioned implementation methods, in certain possible implementation methods, a gear signal of the vehicle corresponding to the target position is determined, including: when the target position is a first position, a forward gear signal is determined as the gear signal of the vehicle, and the first position is a position for turning on the right turn signal of the vehicle; when the target position is a second position, a reverse gear signal is determined as the gear signal of the vehicle, and the second position is a position for turning on the left turn signal of the vehicle; when the target position is a third position, a neutral gear signal is determined as the gear signal of the vehicle, and the third position is a position for not turning on the right turn signal and the left turn signal of the vehicle.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the backup shifter is a wiper switch of the vehicle; based on the backup shifter, the vehicle is controlled to shift gears, including: obtaining the current target gear position of the wiper switch of the vehicle; determining the gear signal of the vehicle corresponding to the target gear position; and based on the gear signal, controlling the vehicle to shift gears.

[0011] In the above technical scheme, in another possible implementation manner, the target gear position of the vehicle's wiper switch can be corresponded to the vehicle's gear signal, so that when the backup shifter is the vehicle's wiper switch, the vehicle's gear signal can be confirmed by obtaining the current target gear position of the vehicle's wiper switch, thereby controlling the vehicle to shift gears based on the gear signal to ensure that the vehicle meets the driver's gear shifting requirements without changing the vehicle's hardware.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in certain possible implementation methods, a gear signal of the vehicle corresponding to the target gear is determined, including: when the target gear is an intermittent wiping gear, a forward gear signal is determined as the gear signal of the vehicle, and the intermittent wiping gear is used to indicate that the wiper of the vehicle swings at a first frequency threshold; when the target gear is a low-speed wiping gear, a neutral gear signal is determined as the gear signal of the vehicle, and the low-speed wiping gear is used to indicate that the wiper of the vehicle swings at a second frequency threshold, and the second frequency threshold is greater than the first frequency threshold; when the target gear is a high-speed wiping gear, a reverse gear signal is determined as the gear signal of the vehicle, and the high-speed wiping gear is used to indicate that the wiper of the vehicle swings at a third frequency threshold, and the third frequency threshold is greater than the second frequency threshold.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the vehicle enters the limp mode due to a failure of the electronic shifter, the backup shifter is activated, including: when the vehicle enters the limp mode due to a failure of the electronic shifter, outputting a first prompt message, the first prompt message being used to prompt whether to switch to the backup shifter; and activating the backup shifter when it is determined to switch to the backup shifter.

[0014] In the above technical solution, when the vehicle enters the limp home mode due to a failure of the electronic shifter, a prompt message on whether to switch to the standby shifter, i.e., the first prompt message, can be output first, so that when it is determined to switch to the standby shifter, i.e., when the driver's feedback is received to determine to switch to the standby shifter, the standby shifter can be activated to prevent the standby shifter from being activated unexpectedly and affecting the driver's car experience.

[0015] In combination with the first aspect and the above-mentioned implementation methods, in certain possible implementation methods, when the vehicle enters the limp mode due to a failure of the electronic shifter, the standby shifter is activated, including: when the vehicle enters the limp mode due to a failure of the electronic shifter, detecting whether the current gear position of the vehicle is consistent with the current gear position of the standby shifter; when the current gear position of the vehicle is inconsistent with the current gear position of the standby shifter, outputting a second prompt message, the second prompt message being used to prompt the adjustment of the current gear position of the standby shifter so that the current gear position of the standby shifter is consistent with the current gear position of the vehicle; when the current gear position of the vehicle is consistent with the current gear position of the standby shifter, activating the standby shifter.

[0016] In the above technical scheme, when the vehicle enters the limp home mode due to a failure of the electronic shifter, it is possible to first detect whether the current gear position of the vehicle is consistent with the current gear position of the standby shifter, so that when the current gear position of the vehicle is inconsistent with the current gear position of the standby shifter, a prompt message for adjusting the current gear position of the standby shifter, i.e., the second prompt message, is output to make the current gear position of the standby shifter consistent with the current gear position of the vehicle, thereby ensuring that the standby shifter is activated when the current gear position of the vehicle is consistent with the current gear position of the standby shifter, thereby avoiding the situation where the vehicle's operating stability is affected by gear conflicts.

[0017] In combination with the first aspect and the above-mentioned implementations, in some possible implementations, the method also includes: when the backup shifter is activated and the backup shifter is the vehicle's turn signal switch, prohibiting the vehicle's turn signal switch from controlling the vehicle's turn signal, and turning on the vehicle's hazard warning flashers; when the backup shifter is activated and the backup shifter is the vehicle's wiper switch, prohibiting the vehicle's wiper switch from controlling the vehicle's wipers, and turning on the vehicle's hazard warning flashers.

[0018] In the above technical scheme, when the backup shifter is activated, the original control function of the backup shifter can be prohibited, that is, when the backup shifter is activated and the backup shifter is the vehicle's turn signal switch, the vehicle's turn signal switch is prohibited from controlling the vehicle's turn signal; when the backup shifter is activated and the backup shifter is the vehicle's wiper switch, the vehicle's wiper switch is prohibited from controlling the vehicle's wiper, so as to avoid the situation where when the backup shifter (the vehicle's turn signal switch / the vehicle's wiper switch) is activated, if the original control function is still retained, it will cause conflicts between the vehicle's control systems, thereby affecting the normal operation of the vehicle; in addition, when the backup shifter is activated, the vehicle's hazard warning flashers can be turned on to alert other road users (for example, other drivers and pedestrians) that the vehicle is in an abnormal state, so that other road users will be more vigilant about the vehicle and take avoidance measures in time, thereby improving the driving safety of the vehicle.

[0019] In a second aspect, a vehicle gear position control device is provided, the device comprising:

[0020] an activation module for activating an alternate shifter in the event that the vehicle enters a limp home mode due to a failure of the electronic shifter, the limp home mode being a vehicle mode in which a shifting function of the vehicle is restricted;

[0021] a release module, for releasing the restriction on the shifting function of the vehicle when the backup shifter is activated;

[0022] The control module is used for controlling the vehicle to shift gears based on the backup shifter.

[0037] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0038] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0039] Before introducing the solutions of the embodiments of the present application, the professional terms that may be involved in the embodiments of the present application are first explained.

[0040] Electronic shifter: It is an intelligent shifting system used in modern cars. It controls the gear changes of the transmission through electrical signals. Compared with traditional mechanical shifters, electronic shifters have higher flexibility and intelligence, and can achieve more precise shifting control. Among them, electronic shifters generally have various forms such as lever type, knob type, button type, dial type and hand-held type.

[0041] Vehicle Control Unit (VCU): It is the core control device used to coordinate and manage the work of various subsystems in modern cars. It is equivalent to the brain of the car, responsible for receiving information from various sensors and controlling the work of key components such as the engine, transmission, braking system, suspension system, etc. based on this information.

[0042] Transmission Control Unit (TCU): is a key electronic control unit used to manage and control the operation of the transmission in modern cars. It is responsible for receiving information from various sensors and controlling the transmission's shifting operations based on this information to ensure that the vehicle can operate smoothly and efficiently under different driving conditions.

[0043] Body Control Module (BCM): It is a key component in the vehicle's electronic system, responsible for monitoring and controlling various functions of the vehicle, including the vehicle's turn signal switch, vehicle's wipers, windows, etc.

[0044] Limp home mode: A protection mode that the vehicle control system automatically enters when it detects certain faults (e.g., electronic shifter fault, engine fault, sensor fault, etc.) to ensure that the vehicle can safely drive to the nearest safe place or repair station. In this mode, the vehicle's performance (e.g., the vehicle's shifting function, the vehicle's output power) will be limited to prevent further damage or potential safety risks.

[0045] As autonomous driving technology matures, more and more vehicles are beginning to use electronic shifters in their braking systems. The main function of the electronic shifter is to receive the driver's shifting operation and, through logical control, output the gear position signal corresponding to the driver's shifting operation to the vehicle controller, so that the vehicle controller controls the transmission to perform the corresponding shifting operation according to the gear position signal.

[0046] However, the electronic shifter is prone to malfunction during use (eg, communication failure, data message abnormality, etc.), causing the vehicle to enter limp home mode, limiting the vehicle's shifting function and causing the vehicle to be unable to meet the driver's shifting needs.

[0047] Based on the above problems, the present application provides a vehicle gear control method, which can meet the driver's gear shifting needs when the vehicle enters limp home mode due to an electronic shifter failure.

[0048] Figure 1 It is a schematic diagram of the implementation environment of a vehicle gear control method provided by the present application.

[0049] For example, Figure 1 As shown, the implementation environment includes a vehicle controller 101 , a transmission controller 102 and a transmission 103 .

[0050] The vehicle controller 101 is an important control unit of the vehicle, which can obtain relevant data of the vehicle, such as the gear signal of the vehicle, the position of the turn signal switch of the vehicle, and the gear position of the wiper switch of the vehicle, and control the driving state of the vehicle based on the relevant parameters, for example, control the gear position of the vehicle. In some embodiments, the vehicle controller 101 sends the gear signal of the vehicle to the transmission controller 102 through a communication bus (such as a controller area network (CAN) bus) in the vehicle to control the gear position of the vehicle.

[0051] In some embodiments, the transmission controller 102 controls the transmission 103 to switch gears based on the vehicle gear signal sent by the vehicle controller 101, thereby achieving the purpose of shifting gears of the vehicle (for example, switching the vehicle's forward gear to a reverse gear, or switching the vehicle's neutral gear to a forward gear, etc.).

[0052] It can be understood that the vehicle in the embodiment of the present application can be a car, a bus, an off-road vehicle or a truck, etc., and the embodiment of the present application is not limited to this.

[0053] Below through Figure 2 The method of the embodiment of the present application is described in detail.

[0054] Figure 2 It is a schematic flow chart of a vehicle gear control method provided in an embodiment of the present application.

[0055] For example, Figure 2 As shown, taking the execution subject as a vehicle controller as an example, the method 200 includes:

[0056] Step 201 , when the vehicle enters a limp home mode due to an electronic shifter failure, activating a backup shifter, wherein the limp home mode refers to a vehicle mode in which a shifting function of the vehicle is restricted.

[0057] Among them, the electronic shifter is a device used to receive the driver's shift operation, convert the driver's shift operation into an electrical signal, namely a shift signal, and send the shift signal to the vehicle controller.

[0058] Optionally, the electronic shifter may be in the form of a hand-held shifter, a shift lever, a knob, a button, or a toggle button. The embodiment of the present application does not specifically limit the form of the electronic shifter.

[0059] The limitation of the gear shifting function of the vehicle can be understood as the gear position of the vehicle being fixed and unable to shift gears, that is, the transmission controller is prohibited from controlling the transmission to switch gears.

[0060] In order to ensure that the driver's shifting needs can still be met when the vehicle enters limp mode due to an electronic shifter failure, in an embodiment of the present application, when the vehicle controller determines that the vehicle enters limp mode due to an electronic shifter failure, the backup shifter can be activated to allow the driver to shift gears of the vehicle through the backup shifter.

[0061] It should be noted that the causes of electronic shifter failure can be divided into the following three types:

[0062] The first is a communication error, that is, the electronic shifter and the vehicle controller cannot communicate normally, that is, the data message (the data message carries the vehicle's shift signal) cannot be sent / received normally.

[0063] Among them, the reasons why the electronic shifter and the vehicle controller cannot communicate normally may be: (1) the line between the electronic shifter and the vehicle controller is broken, short-circuited or has poor contact; (2) the power supply of the communication node between the electronic shifter and the vehicle controller is unstable, etc.

[0064] The second type is data message loss, that is, the data message sent by the electronic shifter to the vehicle controller is lost.

[0065] Specifically, if the vehicle controller does not receive a data packet sent by the electronic shifter within a preset time period, it can be determined that the data packet is lost. It should be understood that the electronic shifter will continue to send data messages to the vehicle controller during the vehicle's driving process, so that the vehicle controller can detect the gear state of the vehicle in a timely manner, thereby adjusting the vehicle's engine speed, torque and other parameters in a timely manner to ensure the stability of the vehicle during driving.

[0066] The third type is data message verification failure. It should be noted that in order to ensure the accuracy and integrity of data transmission, when the vehicle controller receives a data message sent by the electronic shifter, it will verify whether the data message has been changed or lost, so as to determine that the data message has not been changed or lost, and then perform corresponding control operations based on the message data.

[0067] Specifically, when the electronic shifter sends a data message to the vehicle controller, it will generate a first verification code according to the data message, and send the first verification code to the vehicle controller. When the vehicle controller receives the data message, it will also generate a second verification code according to the received data message, and compare the received first verification code with the second verification code generated by itself to see if they are consistent. When it is determined that the first verification code is consistent with the second verification code, a signal indicating that the data message transmission is successful is fed back to the electronic shifter. Otherwise, a signal indicating that the data message transmission failed, i.e., a signal indicating that the data message verification failed is fed back.

[0068] Next, the specific implementation methods of activating the backup shifter by the vehicle controller are introduced in detail in three situations.

[0069] First, in order to prevent the standby shifter from being unexpectedly activated, thereby affecting the driver's driving experience, the vehicle controller activates the standby shifter in a manner that may specifically include the following steps:

[0070] Step 1: When the vehicle enters the limp home mode due to a fault in the electronic shifter, a first prompt message is output, where the first prompt message is used to prompt whether to switch to the standby shifter.

[0071] Specifically, when the vehicle controller determines that the vehicle enters the limp home mode due to a failure of the electronic shifter, a first prompt message will be output, so that the driver can choose whether to switch to the backup shifter according to driving needs after viewing the prompt message.

[0072] Optionally, the first prompt information may be text information or voice information, which is not limited in the embodiment of the present application.

[0073] Exemplarily, when the first prompt information is a text message, the vehicle controller can display the text message on the vehicle's central control electronic screen, and display a virtual key indicating whether to agree to switch to the spare gear shifter below the corresponding text prompt, or use the head-up display (HUD) technology to display the text message on the front windshield of the vehicle, and display a virtual key indicating whether to agree to switch to the spare gear shifter below the corresponding text prompt.

[0074] Among them, the text information can be "The vehicle has entered limp mode, should it be switched to the backup shifter" or "Should the electronic shifter fail and switch to the backup shifter", etc. The virtual button can be "Yes" and "No", or "Agree" / "Disagree", etc., and the embodiment of the present application is not limited to this.

[0075] Step 2: When it is determined to switch to the standby shifter, activate the standby shifter.

[0076] Exemplarily, when the vehicle controller determines to switch to the standby shifter, that is, when the vehicle controller receives information from the driver to determine to switch to the standby shifter, the standby shifter is activated.

[0077] Second, in order to avoid the situation where the vehicle's running stability is affected by the gear conflict of the vehicle, the vehicle controller activates the backup shifter in a manner that may specifically include the following steps:

[0078] Step 1: When the vehicle enters the limp home mode due to a fault in the electronic shifter, detect whether the current gear position of the vehicle is consistent with the current gear position of the standby shifter.

[0079] It should be noted that since the backup shifter has the same function as the electronic shifter, that is, it also has multiple gears (for example, forward gear, reverse gear and neutral gear), in order to avoid the current gear position of the activated backup shifter being inconsistent with the actual gear position of the vehicle, that is, the current gear position of the vehicle, in this embodiment, when the vehicle controller determines that the vehicle enters the limp home mode due to a failure of the electronic shifter, it is necessary to first detect whether the current gear position of the vehicle is consistent with the current gear position of the backup shifter, so as to activate the backup shifter when it is determined that the current gear position of the vehicle is consistent with the current gear position of the backup shifter.

[0080] In one possible implementation, the backup shifter may be the vehicle's turn signal switch / vehicle's wiper switch. In order to enable the vehicle controller to determine the vehicle gear position currently indicated by the vehicle's turn signal switch / vehicle's wiper switch before activating the vehicle's turn signal switch / vehicle's wiper switch, that is, before the vehicle's turn signal switch / vehicle's wiper switch starts to execute the task of controlling the vehicle to shift gears, the developer may pre-store in the vehicle controller the vehicle gear positions corresponding to the position information of the turn signal switches of different vehicles, or the vehicle gear positions corresponding to the gear information of the wiper switches of different vehicles, so that when the vehicle controller determines that the vehicle enters the limp home mode due to a failure of the electronic shifter, the current gear position of the backup shifter may be determined by obtaining the position information of the vehicle's turn signal switch / the gear information of the vehicle's wiper switch.

[0081] Specifically, after the vehicle controller determines the current gear position of the vehicle through the transmission controller, and determines the current gear position of the standby gear shifter by pre-storing the correspondence between the vehicle's turn signal switch / the vehicle's wiper switch and the vehicle's gear position, the current gear position of the vehicle will be compared with the current gear position of the standby gear shifter, and when it is determined that the current gear position of the vehicle is consistent with the current gear position of the standby gear shifter, the standby gear shifter will be activated.

[0082] Step 2: When the current gear position of the vehicle is inconsistent with the current gear position of the standby shifter, output a second prompt message, the second prompt message being used to prompt the adjustment of the current gear position of the standby shifter so that the current gear position of the standby shifter is consistent with the current gear position of the vehicle.

[0083] Specifically, when the vehicle controller determines that the current gear position of the vehicle is inconsistent with the current gear position of the standby gear shifter, a second prompt message can be output so that the driver can adjust the gear position of the standby gear shifter in time after checking the prompt message, so that the current gear position of the standby gear shifter is consistent with the current gear position of the vehicle, thereby ensuring that the current gear position of the activated standby gear shifter is consistent with the current gear position of the vehicle.

[0084] Optionally, the second prompt information may be text information or voice information, which is not limited in the embodiment of the present application.

[0085] Exemplarily, when the second prompt information is text information, the vehicle controller can display the text information on the central control electronic screen of the vehicle, or display the text information on the front windshield of the vehicle using head-up display (HUD) technology.

[0086] For example, when the vehicle's current gear position is "forward gear" and the standby gear shifter's current gear position is "reverse gear", the text message may be "Please adjust the current gear position of the standby gear shifter to "forward gear"" or "The standby gear shifter is about to be activated, please adjust it to the "forward gear" that is consistent with the vehicle's current gear position" etc.

[0087] Step 3: When the current gear position of the vehicle is consistent with the current gear position of the standby gear shifter, activate the standby gear shifter.

[0088] Exemplarily, when the vehicle controller detects that the current gear position of the vehicle is consistent with the current gear position of the standby shifter, or when the vehicle controller determines that the current gear position of the standby shifter has been adjusted to a gear position consistent with the current gear position of the vehicle, the standby shifter is activated to ensure that the current gear position of the activated standby shifter is consistent with the current gear position of the vehicle, thereby avoiding the situation where the current gear position of the activated standby shifter is inconsistent with the current gear position of the vehicle, that is, the vehicle's operating stability is affected by the vehicle's gear conflict.

[0089] Third, in order to prevent the standby shifter from being unexpectedly activated, thereby affecting the driver's driving experience, and also to avoid the situation where the vehicle's running stability is affected by the gear conflict, the vehicle controller activates the standby shifter in a manner that specifically includes the following steps:

[0090] Step 1: When the vehicle enters the limp home mode due to a fault in the electronic shifter, output a first prompt message to prompt whether to switch to the standby shifter.

[0091] Step 2: When it is determined to switch to the standby shifter, detect whether the current gear position of the vehicle is consistent with the current gear position of the standby shifter.

[0092] Step three: when the current gear position of the vehicle is inconsistent with the current gear position of the standby gear shifter, output a second prompt message to prompt the user to adjust the current gear position of the standby gear shifter so that the current gear position of the standby gear shifter is consistent with the current gear position of the vehicle.

[0093] Step 4: When the current gear position of the vehicle is consistent with the current gear position of the standby gear shifter, activate the standby gear shifter.

[0094] The implementation of steps one to four may refer to the above embodiments and will not be described in detail here.

[0095] Step 202 , when the standby shifter is activated, release the restriction on the shifting function of the vehicle.

[0096] It should be understood that when the vehicle enters limp home mode due to a failure of the electronic shifter, the vehicle's shifting function will be restricted, that is, the transmission controller will be prohibited from controlling the transmission to switch gears. Therefore, in order to ensure that when the backup shifter is activated, the transmission controller can control the transmission to switch gears according to the shift signal sent by the backup shifter, in this embodiment of the present application, when the vehicle controller determines that the backup shifter is activated, it is necessary to lift the restriction on the vehicle's shifting function, that is, it is necessary to restore the transmission controller's control over the transmission to ensure that the transmission controller can control the transmission to switch gears according to the shift signal sent by the backup shifter, thereby meeting the driver's shifting needs.

[0097] It should be noted that, when the vehicle controller determines that the vehicle has entered limp home mode due to a failure of the electronic shifter, it will obtain the current gear position of the transmission through the transmission controller, and send a control instruction to prohibit control of the transmission to the transmission controller, so as to lock the transmission in the current gear position, that is, the vehicle's shifting function is restricted; when the vehicle controller determines that the standby shifter is activated, it will send a control instruction to allow control of the transmission to the transmission controller, so that the transmission can receive the control of the transmission controller and perform gear switching, that is, the vehicle's shifting function is unrestricted.

[0098] Step 203, controlling the vehicle to shift gears based on the standby shifter.

[0099] Specifically, when the backup shifter is activated, the vehicle controller can determine the gear signal sent by the backup shifter and send the gear shift signal to the transmission controller, so that the transmission controller controls the transmission to switch gears according to the gear signal, thereby achieving the purpose of shifting the vehicle.

[0100] It can be seen from the above embodiments that the backup shifter can be a turn signal switch of the vehicle or a wiper switch of the vehicle. Therefore, when the vehicle controller controls the vehicle to shift gears based on the backup shifter, there can be at least two situations.

[0101] Exemplarily, the embodiment of the present application proposes two ways of controlling the vehicle to shift gears. The following respectively introduces two ways of controlling the vehicle to shift gears based on the standby shifter by the vehicle controller:

[0102] First, when the backup shifter is a wiper switch of the vehicle, the specific implementation steps of controlling the vehicle to shift gears based on the wiper switch of the vehicle are as follows:

[0103] Step 1: Get the current target position of the vehicle's turn signal switch.

[0104] The target position includes a first position, a second position and a third position.

[0105] It should be noted that the first position is the position for turning on the right turn signal of the vehicle, the second position is the position for turning on the left turn signal of the vehicle, and the third position is the position for not turning on the right turn signal and the left turn signal of the vehicle. It is understandable that the turn signal switch is usually located on the steering column of the vehicle, and the driver can adjust the position of the turn signal switch by toggling the switch to control the on / off of the vehicle's turn signal.

[0106] Among them, the method for the vehicle controller to obtain the current target position of the vehicle's turn signal switch: the vehicle controller can obtain the current target position of the turn signal switch through components such as the body controller (Body Control Module, BCM) or the turn signal controller, and the embodiment of the present application is not limited to this.

[0107] Step 2: Determine the gear position signal of the vehicle corresponding to the target position.

[0108] Specifically, the developer can store the current position of the turn signal switch, that is, the correspondence table between the target position and the gear signal of the vehicle in the vehicle controller in advance, so that after the vehicle controller obtains the current target position of the vehicle's turn signal switch, the gear signal of the vehicle can be determined according to the pre-set relationship correspondence table.

[0109] For example, the corresponding relationship table between the current target position of the turn signal switch of the vehicle and the gear position signal of the vehicle can be shown in the following Table 1:

[0110] Table 1

[0111] Target location Gear position signal First Position Forward gear signal Second Position Reverse gear signal Third Position Neutral signal …… ……

[0112] It should be noted that when the vehicle controller obtains that the current target position of the vehicle's turn signal switch is the first position, the forward gear signal can be determined as the vehicle's gear signal according to Table 1 and the first position; when the vehicle controller obtains that the current target position of the vehicle's turn signal switch is the second position, the reverse gear signal can be determined as the vehicle's gear signal according to Table 1 and the first position; when the vehicle controller obtains that the current target position of the vehicle's turn signal switch is the third position, the neutral gear signal can be determined as the vehicle's gear signal according to Table 1 and the third position.

[0113] Step 3: Based on the gear position signal, control the vehicle to shift gears.

[0114] Specifically, after the vehicle controller determines the gear signal of the vehicle, the gear signal can be sent to the transmission controller, so that the transmission controller controls the transmission to switch gears according to the gear signal, thereby achieving the purpose of shifting the vehicle.

[0115] In this embodiment, the target position of the vehicle's turn signal switch can be matched with the vehicle's gear signal, so that when the backup shifter is the vehicle's turn signal switch, the vehicle's gear signal can be determined by obtaining the current target position of the vehicle's turn signal switch, thereby controlling the vehicle to shift gears based on the gear signal to ensure that the vehicle meets the driver's gear shifting needs without changing the vehicle's hardware.

[0116] Second, when the standby shifter is a wiper switch of the vehicle, the specific implementation steps of controlling the vehicle to shift gears based on the wiper switch of the vehicle are as follows:

[0117] Step 1: Get the current target gear position of the vehicle's wiper switch.

[0118] Among them, the target gear includes an intermittent scraping and brushing gear, a low-speed scraping and brushing gear, and a high-speed scraping and brushing gear.

[0119] It should be noted that different gear positions of the wiper switch can make the vehicle's wiper swing at different frequencies. Specifically, when the target gear position is the intermittent wiper gear position, the vehicle's wiper will swing at a first frequency threshold; when the target gear position is the low-speed wiper gear position, the vehicle's wiper will swing at a second frequency threshold; when the target gear position is the high-speed wiper gear position, the vehicle's wiper will swing at a third frequency threshold, wherein the second frequency threshold is greater than the first frequency threshold, and the third frequency threshold is greater than the second frequency threshold, that is, when the vehicle's wiper switch is adjusted from the intermittent wiper gear position to the high-speed wiper gear position, the swing frequency of the vehicle's wiper will become higher and higher. It is understandable that the vehicle's wiper switch is usually located on the vehicle's steering wheel column, and the driver can adjust the gear position of the wiper switch by toggling or rotating to control the vehicle's wiper.

[0120] Among them, the method for the vehicle controller to obtain the current target gear position of the vehicle's wiper switch: the vehicle controller can obtain the current target gear position of the wiper switch through components such as the body controller module (Body Control Module, BCM) or the wiper switch controller, and the embodiments of the present application are not limited to this.

[0121] Step 2: Determine the gear position signal of the vehicle corresponding to the target gear position.

[0122] Specifically, the developer can pre-store the current gear position of the wiper switch, that is, the correspondence table between the target gear position and the gear signal of the vehicle in the vehicle controller, so that after the vehicle controller obtains the current target gear position of the vehicle's wiper switch, the vehicle's gear signal can be determined according to the pre-set relationship correspondence table.

[0123] For example, the corresponding relationship table between the current target gear position of the wiper switch of the vehicle and the gear position signal of the vehicle can be shown in the following Table 2:

[0124] Table 2

[0125] Target gear Gear position signal Intermittent scraping position Forward gear signal Low speed scraping gear Neutral signal High speed scraping gear Reverse gear signal …… ……

[0126] It should be noted that when the vehicle controller obtains that the current target gear position of the vehicle's wiper switch is the intermittent wiper gear position, the forward gear signal can be determined as the vehicle's gear signal according to Table 2 and the intermittent wiper gear position; when the vehicle controller obtains that the current target gear position of the vehicle's wiper switch is the low-speed wiper gear position, the neutral gear signal can be determined as the vehicle's gear signal according to Table 2 and the low-speed wiper gear position; when the vehicle controller obtains that the current target gear position of the vehicle's wiper switch is the high-speed wiper gear position, the reverse gear signal can be determined as the vehicle's gear signal according to Table 2 and the high-speed wiper gear position.

[0127] Step 3: Based on the gear position signal, control the vehicle to shift gears.

[0128] The implementation of step three can refer to the above embodiment and will not be described again here.

[0129] In this embodiment, the target gear position of the vehicle's wiper switch can be matched with the vehicle's gear signal, so that when the backup shifter is the vehicle's wiper switch, the vehicle's gear signal can be determined by obtaining the current target gear position of the vehicle's wiper switch, thereby controlling the vehicle to shift gears based on the gear signal, thereby ensuring that the vehicle meets the driver's gear shifting needs without changing the vehicle's hardware.

[0130] In summary, the vehicle gear control method provided in the embodiment of the present application can activate the backup shifter when the vehicle enters the limp mode (a vehicle mode in which the vehicle's shifting function is restricted) due to a fault in the electronic shifter, thereby releasing the restriction on the vehicle's shifting function when the backup shifter is activated, and then controlling the vehicle to shift gears based on the backup shifter, thereby meeting the driver's shifting needs, and avoiding the situation where the vehicle cannot meet the driver's shifting needs when the vehicle enters the limp mode due to a fault in the electronic shifter. The backup shifter can be the vehicle's turn signal switch / vehicle's wiper switch, thereby ensuring that the vehicle meets the driver's shifting needs without changing the vehicle's hardware.

[0131] In one possible implementation, when the backup shifter is activated, the original control function of the backup shifter can be disabled, that is, when the backup shifter is activated and the backup shifter is the vehicle's turn signal switch, the vehicle's turn signal switch is disabled from controlling the vehicle's turn signal; when the backup shifter is activated and the backup shifter is the vehicle's wiper switch, the vehicle's wiper switch is disabled from controlling the vehicle's wiper, thereby avoiding a situation in which, when the backup shifter (vehicle's turn signal switch / vehicle's wiper switch) is activated, the original control function is still retained, which will cause conflicts between the vehicle's control systems, thereby affecting the normal operation of the vehicle.

[0132] In addition, when the backup shifter is activated, the vehicle controller can turn on the vehicle's hazard warning lights (also known as the vehicle's double flash lights) to alert other road users (for example, other drivers and pedestrians) that the vehicle is in an abnormal state, so that other road users can be more vigilant about the vehicle and take avoidance measures in time, thereby improving the driving safety of the vehicle.

[0133] It should be noted that in the embodiment of the present application, when the vehicle controller determines that the vehicle has exited the limp home mode, that is, when the vehicle controller determines that the vehicle's electronic shifter fault has been eliminated, the backup shifter (the vehicle's turn signal switch / the vehicle's wiper switch) can be deactivated to restore the vehicle's turn signal switch / the vehicle's wiper switch to its original control function.

[0144] In one possible implementation, the device also includes a detection module, which is used to detect whether the current gear position of the vehicle is consistent with the current gear position of the standby shifter when the vehicle enters the limp mode due to a failure of the electronic shifter; the output module is also used to output a second prompt message when the current gear position of the vehicle is inconsistent with the current gear position of the standby shifter, and the second prompt message is used to prompt the adjustment of the current gear position of the standby shifter so that the current gear position of the standby shifter is consistent with the current gear position of the vehicle; the activation module 301 is specifically used to activate the standby shifter when the current gear position of the vehicle is consistent with the current gear position of the standby shifter.

[0145] In one possible implementation, the device also includes a prohibition module, which is used to prohibit the vehicle's turn signal switch from controlling the vehicle's turn signal when the backup shifter is activated and the backup shifter is the vehicle's turn signal switch; when the backup shifter is activated and the backup shifter is the vehicle's wiper switch, prohibit the vehicle's wiper switch from controlling the vehicle's wiper. The control module 303 is specifically used to turn on the vehicle's hazard warning flashers.
