Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, and more particularly, to a vehicle gear control method, device and vehicle in the technical field of vehicles. BACKGROUND

[0002] With the gradual maturity of automatic driving technology, more and more vehicles begin to use electronic shifters in the braking system. Electronic shifters generally have various forms such as lever type, knob type, button type, dial type, and handle type. The main function of the electronic shifter is to receive the shift operation of the driver, and output the gear 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 signal.

[0003] However, the electronic shifter is prone to failure during use, so that the vehicle enters a limp mode, the shift function of the vehicle is limited, and the vehicle cannot meet the shift demand of the driver. SUMMARY

[0004] The present application provides a vehicle gear control method, device and vehicle, which can meet the shift demand of the driver when the vehicle enters a limp mode due to electronic shifter failure.

[0005] In a first aspect, a vehicle gear control method is provided, which includes: activating a backup shifter when the vehicle enters a limp mode due to electronic shifter failure, the limp mode being a vehicle mode in which the shift function of the vehicle is limited; removing the limitation on the shift function of the vehicle when the backup shifter is activated; and controlling the vehicle to shift based on the backup shifter.

[0006] In the above technical solution, the present application provides a vehicle gear control method: when the vehicle enters a limp mode (a vehicle mode in which the shift function of the vehicle is limited) due to electronic shifter failure, a backup shifter is activated, so that when the backup shifter is activated, the limitation on the shift function of the vehicle is removed, and then the vehicle is controlled to shift based on the backup shifter, thereby meeting the shift demand of the driver and avoiding the situation that the vehicle cannot meet the shift demand of the driver when the vehicle enters a limp mode due to electronic shifter failure.

[0007] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the backup shifter is a turn signal switch of the vehicle; and the controlling the vehicle to shift based on the backup shifter includes: obtaining a target position of the turn signal switch of the vehicle; determining a gear signal of the vehicle corresponding to the target position; and controlling the vehicle to shift based on the gear signal.

[0008] In the above technical solution, in a possible implementation, the target position of the vehicle's turn signal switch can be corresponded to the gear signal of the vehicle, so that in the case that the backup gear shifter is the vehicle's turn signal switch, the gear signal of the vehicle can be determined by acquiring the target position of the vehicle's turn signal switch currently, and the vehicle can be controlled to shift gears based on the gear signal, so as to ensure that the vehicle meets the gear shifting demand of the driver without changing the hardware of the vehicle.

[0009] In combination with the first aspect and the above implementation, in some possible implementations, determining the gear signal of the vehicle corresponding to the target position comprises: in the case that the target position is a first position, determining a forward gear signal as the gear signal of the vehicle, the first position being a position of turning on the right turn signal of the vehicle; in the case that the target position is a second position, determining a reverse gear signal as the gear signal of the vehicle, the second position being a position of turning on the left turn signal of the vehicle; in the case that the target position is a third position, determining a neutral gear signal as the gear signal of the vehicle, the third position being a position of 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 implementation, in some possible implementations, the backup gear shifter is a wiper switch of the vehicle; and controlling the vehicle to shift gears based on the backup gear shifter comprises: acquiring a target gear of the wiper switch of the vehicle currently; determining a gear signal of the vehicle corresponding to the target gear; and controlling the vehicle to shift gears based on the gear signal.

[0011] In the above technical solution, in another possible implementation, the target gear of the wiper switch of the vehicle can be corresponded to the gear signal of the vehicle, so that in the case that the backup gear shifter is the wiper switch of the vehicle, the gear signal of the vehicle can be determined by acquiring the target gear of the wiper switch of the vehicle currently, and the vehicle can be controlled to shift gears based on the gear signal, so as to ensure that the vehicle meets the gear shifting demand of the driver without changing the hardware of the vehicle.

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

[0013] With reference to the first aspect and the above implementation manners, in some possible implementation manners, the activating the backup gear shifter in the case that the vehicle enters the limp-home mode due to the electronic gear shifter failure comprises: outputting first prompt information in the case that the vehicle enters the limp-home mode due to the electronic gear shifter failure, the first prompt information being used to prompt whether to switch to the backup gear shifter; and activating the backup gear shifter in the case that it is determined to switch to the backup gear shifter.

[0014] In the above technical solution, in the case that the vehicle enters the limp-home mode due to the electronic gear shifter failure, first prompt information about whether to switch to the backup gear shifter can be output first, so that the backup gear shifter is activated in the case that it is determined to switch to the backup gear shifter, i.e., in the case that information about determining to switch to the backup gear shifter fed back by the driver is received, so as to prevent the backup gear shifter from being activated unexpectedly and affect the driving experience of the driver.

[0015] With reference to the first aspect and the above implementation manners, in some possible implementation manners, the activating the backup gear shifter in the case that the vehicle enters the limp-home mode due to the electronic gear shifter failure comprises: detecting whether the current gear of the vehicle is consistent with the current gear of the backup gear shifter in the case that the vehicle enters the limp-home mode due to the electronic gear shifter failure; outputting second prompt information in the case that the current gear of the vehicle is not consistent with the current gear of the backup gear shifter, the second prompt information being used to prompt adjusting the current gear of the backup gear shifter so as to make the current gear of the backup gear shifter consistent with the current gear of the vehicle; and activating the backup gear shifter in the case that the current gear of the vehicle is consistent with the current gear of the backup gear shifter.

[0016] In the above technical solution, in the case that the vehicle enters the limp-home mode due to the electronic gear shifter failure, whether the current gear of the vehicle is consistent with the current gear of the backup gear shifter can be detected first, so that prompt information about adjusting the current gear of the backup gear shifter, i.e., second prompt information, is output in the case that the current gear of the vehicle is not consistent with the current gear of the backup gear shifter, so as to make the current gear of the backup gear shifter consistent with the current gear of the vehicle, thereby guaranteeing that the backup gear shifter is activated in the case that the current gear of the vehicle is consistent with the current gear of the backup gear shifter, and avoiding the case that the vehicle running stability is affected due to gear conflict.

[0017] With reference to the first aspect and the above implementation manners, in some possible implementation manners, the method further comprises: in the case that the backup gear shifter is activated and the backup gear shifter is a turn signal switch of the vehicle, prohibiting the turn signal switch of the vehicle from controlling the turn signal of the vehicle, and turning on a hazard warning flasher of the vehicle; and in the case that the backup gear shifter is activated and the backup gear shifter is a wiper switch of the vehicle, prohibiting the wiper switch of the vehicle from controlling the wiper of the vehicle, and turning on the hazard warning flasher of the vehicle.

[0018] In the above technical solution, in the case that the backup gear selector is activated, the original control function of the backup gear selector can be prohibited, that is, in the case that the backup gear selector is activated and the backup gear selector is the turn signal switch of the vehicle, the turn signal switch of the vehicle is prohibited from controlling the turn signal of the vehicle; in the case that the backup gear selector is activated and the backup gear selector is the wiper switch of the vehicle, the wiper switch of the vehicle is prohibited from controlling the wiper of the vehicle, so as to avoid the conflict between the control systems of the vehicle in the case that the original control function is still retained in the case that the backup gear selector (the turn signal switch of the vehicle / the wiper switch of the vehicle) is activated, thereby affecting the normal operation of the vehicle. In addition, in the case that the backup gear selector is activated, the hazard warning flasher of the vehicle can be turned on to prompt other road users (for example, other drivers and pedestrians) that the vehicle is in an abnormal state, so that the other road users increase the vigilance of the vehicle and take evasive measures in time, thereby improving the driving safety of the vehicle.

[0037] The technical solutions in the present application will be described in detail below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0038] Hereinafter, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

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

[0040] Electronic Shifter: It is an intelligent shift system used in modern cars, which controls the gear change of the transmission through electrical signals. Compared with traditional mechanical shifters, electronic shifters have higher flexibility and intelligence level, and can achieve more precise shift control. Among them, electronic shifters generally have lever type, knob type, button type, dial type and waist type, etc.

[0041] Vehicle Control Unit (VCU): It is a 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 engines, transmissions, braking systems, suspension systems, etc. based on these information.

[0042] Transmission Control Unit (TCU): It 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 shift operation of the transmission based on these information to ensure that the vehicle can run 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, the vehicle's wiper, the vehicle's window, etc.

[0044] Limp Mode: It is a protection mode that the vehicle control system automatically enters when it detects some faults (such as electronic shifter failure, engine failure, sensor failure, etc.) in order to ensure that the vehicle can safely drive to the nearest safe place or repair station. In this mode, the performance of the vehicle (such as the shift function of the vehicle, the output power of the vehicle) will be limited to prevent further damage or potential safety risks.

[0045] With the gradual maturity of automatic driving technology, more and more vehicles' braking systems begin to use electronic shifters. The main function of the electronic shifter is to receive the shift operation of the driver and output the corresponding gear signal to the vehicle control unit through logical control, so that the vehicle control unit controls the transmission to perform the corresponding shift operation according to the gear signal.

[0046] However, the electronic gear shifter is prone to failure (for example, communication failure, abnormal data packet, etc.) during use, so that the vehicle enters a limp mode, the gear shifting function of the vehicle is limited, and the vehicle cannot meet the gear shifting demand of the driver.

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

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

[0049] For example, as shown in Figure 1 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 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 of the vehicle. In some embodiments, the vehicle controller 101 sends the gear signal of the vehicle to the transmission controller 102 through the communication bus (such as the Controller Area Network (CAN) bus) in the vehicle, to control the gear of the vehicle.

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

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

[0053] The method of the embodiments of the present application will be described in detail below. Figure 2 The method of the embodiments of the present application will be described in detail below.

[0054] Figure 2 is a schematic flowchart of a vehicle gear control method provided by the embodiments of the present application.

[0055] For example, as shown in Figure 2 Taking the vehicle controller as an example, the method 200 includes:

[0056] Step 201, in the case that the vehicle enters the limp mode due to the electronic gear shifter failure, the backup gear shifter is activated, the limp mode refers to a vehicle mode in which the gear shifting function of the vehicle is limited.

[0057] The electronic gear shifter is a device for receiving the gear shifting operation of the driver, converting the gear shifting operation of the driver into an electrical signal, i.e., a gear shifting signal, and sending the gear shifting signal to the vehicle controller.

[0058] Optionally, the electronic gear shifter can be in the form of a handle, a lever, a knob, a button or a dial, and the form of the electronic gear shifter is not limited in the embodiments of the present application.

[0059] The gear shifting function of the vehicle being limited can be understood as the gear position of the vehicle being fixed and unable to be shifted, i.e., the transmission controller is prohibited from controlling the gear shifting of the transmission.

[0060] In order to meet the gear shifting demand of the driver in the case that the vehicle enters the limp mode due to the electronic gear shifter failure, in the embodiments of the present application, the backup gear shifter can be activated in the case that the vehicle controller determines that the vehicle enters the limp mode due to the electronic gear shifter failure, so that the driver can shift the gears of the vehicle through the backup gear shifter.

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

[0062] The first type is communication error, i.e., the electronic gear shifter and the vehicle controller cannot normally communicate, i.e., cannot normally send / receive data packets (the data packets carry the gear shifting signal of the vehicle).

[0063] The reason why the electronic gear shifter and the vehicle controller cannot normally communicate can be that: (1) there is an open circuit, a short circuit or poor contact between the electronic gear shifter and the vehicle controller; (2) the power supply of the communication node of the electronic gear shifter and the vehicle controller is unstable, etc.

[0064] The second type is data packet loss, i.e., the data packet sent by the electronic gear shifter to the vehicle controller is lost.

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

[0066] Thirdly, the data packet verification fails. It should be noted that, in order to ensure the accuracy and integrity of data transmission, in the case that the whole vehicle controller receives the data packet sent by the electronic gear shifter, it is verified whether the data packet is changed or lost, so as to determine that the data packet is not changed or lost, and then the corresponding control operation is performed according to the packet data.

[0067] Specifically, when the electronic gear shifter sends the data packet to the whole vehicle controller, a first check code corresponding to the data packet is generated, and the first check code is sent to the whole vehicle controller. In the case that the whole vehicle controller receives the data packet, a second check code corresponding to the received data packet is generated, and whether the received first check code is consistent with the generated second check code is compared, so as to determine that the first check code is consistent with the second check code, and feedback the signal of successful transmission of the data packet to the electronic gear shifter, otherwise, feedback the signal of failed transmission of the data packet, that is, the signal of failed verification of the data packet.

[0068] Next, three cases are introduced in detail, the specific implementation of the whole vehicle controller activating the backup gear shifter.

[0069] Firstly, in order to prevent the backup gear shifter from being activated unexpectedly, thereby affecting the driving experience of the driver, the specific implementation of the whole vehicle controller activating the backup gear shifter can include the following steps:

[0070] Step one, in the case that the vehicle enters the limp mode due to the failure of the electronic gear shifter, output the first prompt information, and the first prompt information is used to prompt whether to switch to the backup gear shifter.

[0071] Specifically, in the case that the whole vehicle controller determines that the vehicle enters the limp mode due to the failure of the electronic gear shifter, the first prompt information is outputted, so that the driver can choose whether to switch to the backup gear shifter according to the driving demand after viewing the prompt information.

[0072] Optionally, the first prompt information can be text information or voice information, and the embodiments of the present application do not limit this.

[0073] For example, in the case that the first prompt information is text information, the whole vehicle controller can display the text information on the central electronic screen of the vehicle, and display the virtual key of whether to agree to switch to the backup gear shifter below the corresponding text prompt, or display the text information on the front windshield of the vehicle by using the head-up display (HUD) technology, and display the virtual key of whether to agree to switch to the backup gear shifter below the corresponding text prompt.

[0074] The text information can be "the vehicle has entered the limp mode, whether to switch to the backup gear shifter" or "whether the electronic gear shifter fault switches to the backup gear shifter", and the virtual button can be "yes" and "no", or "agree" / "disagree", and the embodiments of the present application are not limited in this regard.

[0075] Step two, in the case of determining to switch to the backup gear shifter, activating the backup gear shifter.

[0076] For example, in the case of determining to switch to the backup gear shifter by the vehicle controller, i.e. in the case of receiving the information of determining to switch to the backup gear shifter by the driver feedback, activating the backup gear shifter.

[0077] Secondly, in order to avoid the impact of the gear conflict of the vehicle on the stability of the vehicle, the vehicle controller activates the backup gear shifter, which can include the following steps:

[0078] Step one, in the case of the vehicle entering the limp mode due to the electronic gear shifter fault, detecting whether the current gear of the vehicle is consistent with the current gear of the backup gear shifter.

[0079] It should be noted that since the backup gear shifter has the same function as the electronic gear shifter, i.e. also has multiple gears (for example, forward gear, reverse gear and neutral gear), in order to avoid the case that the current gear of the activated backup gear shifter is inconsistent with the actual driving gear of the vehicle, i.e. the current gear of the vehicle, in this embodiment, in the case of determining that the vehicle enters the limp mode due to the electronic gear shifter fault, the current gear of the vehicle needs to be detected first. Consistent with the current gear of the backup gear shifter, so as to activate the backup gear shifter in the case of determining that the current gear of the vehicle is consistent with the current gear of the backup gear shifter.

[0080] In a possible implementation, the backup gear shifter can be the vehicle's turn signal switch / vehicle's wiper switch, in order to make the vehicle controller determine the vehicle gear represented by the position information of the vehicle's turn signal switch / vehicle's wiper switch before activating the vehicle's turn signal switch / vehicle's wiper switch, i.e. before the vehicle's turn signal switch / vehicle's wiper switch starts to perform the task of controlling the vehicle to shift gears, the developer can pre-store the position information of the vehicle's turn signal switch of different vehicles corresponding to the vehicle gear represented, or the position information of the vehicle's wiper switch of different vehicles corresponding to the vehicle gear represented, in the vehicle controller, so that in the case of determining that the vehicle enters the limp mode due to the electronic gear shifter fault, the current gear of the backup gear shifter can be determined by obtaining the position information of the vehicle's turn signal switch / the position information of the vehicle's wiper switch.

[0081] Specifically, after the vehicle controller determines the current gear of the vehicle through the transmission controller, and determines the current gear of the backup gearshift through the pre-stored correspondence between the turn signal switch of the vehicle / the wiper switch of the vehicle and the gear of the vehicle, the current gear of the vehicle and the current gear of the backup gearshift are compared, and the backup gearshift is activated when it is determined that the current gear of the vehicle is consistent with the current gear of the backup gearshift.

[0082] Step two, when the current gear of the vehicle is inconsistent with the current gear of the backup gearshift, outputting second prompt information, which is used to prompt adjusting the current gear of the backup gearshift so as to make the current gear of the backup gearshift consistent with the current gear of the vehicle.

[0083] Specifically, when the vehicle controller determines that the current gear of the vehicle is inconsistent with the current gear of the backup gearshift, the second prompt information can be outputted so that the driver can timely adjust the gear of the backup gearshift when seeing the prompt information, so as to make the current gear of the backup gearshift consistent with the current gear of the vehicle, and further ensure that the current gear of the activated backup gearshift is consistent with the current gear of the vehicle.

[0084] Optionally, the second prompt information can be text information or voice information, and the embodiments of the present application do not make any limitation in this regard.

[0085] For example, when the current gear of the vehicle is "forward gear" and the current gear of the backup gearshift is "reverse gear", the text information can be "please adjust the current gear of the backup gearshift to "forward gear" or "the backup gearshift will be activated, please adjust to "forward gear" consistent with the current gear of the vehicle".

[0086] For example, when the current gear of the vehicle is "forward gear" and the current gear of the backup gearshift is "reverse gear", the text information can be "please adjust the current gear of the backup gearshift to "forward gear" or "the backup gearshift will be activated, please adjust to "forward gear" consistent with the current gear of the vehicle".

[0087] Step three, activating the backup gearshift when the current gear of the vehicle is consistent with the current gear of the backup gearshift.

[0088] For example, when the vehicle controller detects that the current gear of the vehicle is consistent with the current gear of the backup gearshift, or when the vehicle controller determines that the current gear of the backup gearshift has been adjusted to the gear consistent with the current gear of the vehicle, the backup gearshift is activated, so as to ensure that the current gear of the activated backup gearshift is consistent with the current gear of the vehicle, and avoid the situation that the current gear of the activated backup gearshift is inconsistent with the current gear of the vehicle, i.e. the situation that the gear conflict of the vehicle affects the running stability of the vehicle.

[0089] Thirdly, in order to prevent the backup shifter from being activated unexpectedly, thereby affecting the driving experience of the driver, while also avoiding the situation that the gear conflict affects the stability of the vehicle operation, the activation mode of the backup shifter by the vehicle controller can specifically include the following steps:

[0090] Step one, in the case that the vehicle enters the limp mode due to the failure of the electronic shifter, output the first prompt information to prompt whether to switch to the backup shifter.

[0091] Step two, in the case of determining to switch to the backup shifter, detect whether the current gear of the vehicle is consistent with the current gear of the backup shifter.

[0092] Step three, in the case that the current gear of the vehicle is not consistent with the current gear of the backup shifter, output the second prompt information to prompt adjusting the current gear of the backup shifter so that the current gear of the backup shifter is consistent with the current gear of the vehicle.

[0093] Step four, in the case that the current gear of the vehicle is consistent with the current gear of the backup shifter, activate the backup shifter.

[0094] Among them, the implementation of the steps one to four can refer to the above embodiments, which will not be repeated here.

[0095] Step 202, in the case that the backup shifter is activated, release the restriction on the shifting function of the vehicle.

[0096] It should be understood that since the shifting function of the vehicle will be restricted, that is, the transmission controller will be prohibited from controlling the gear shifting of the transmission, in the case that the vehicle enters the limp mode due to the failure of the electronic shifter, in order to ensure that the transmission controller can control the gear shifting of the transmission according to the shifting signal sent by the backup shifter in the case that the backup shifter is activated, in the embodiments of the present application, the restriction on the shifting function of the vehicle needs to be released, that is, the control of the transmission controller on the transmission needs to be restored, so as to ensure that the transmission controller can control the gear shifting of the transmission according to the shifting signal sent by the backup shifter, so as to meet the shifting demand of the driver.

[0097] It should be noted that, in the case that the vehicle controller determines that the vehicle enters the limp mode due to the electronic gear shifter failure, the current gear of the transmission is obtained through the transmission controller, and a control instruction for prohibiting the control of the transmission is sent to the transmission controller to lock the transmission at the current gear, that is, the gear shifting function of the vehicle is limited; in the case that the vehicle controller determines that the backup gear shifter is activated, a control instruction for allowing the control of the transmission is sent to the transmission controller, so that the transmission can receive the control of the transmission controller to switch the gear, that is, the gear shifting function of the vehicle is released.

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

[0099] Specifically, in the case that the backup gear shifter is activated, the vehicle controller can determine the gear signal sent by the backup gear shifter and send the gear 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 controlling the vehicle to shift gears.

[0100] As can be seen from the above embodiment, the backup gear shifter can be the turn signal switch of the vehicle or the wiper switch of the vehicle, so when the vehicle controller controls the vehicle to shift gears based on the backup gear shifter, it can be divided into at least two cases.

[0101] For example, the embodiments of the present application propose two ways to control the vehicle to shift gears, and the following will introduce two ways of the vehicle controller controlling the vehicle to shift gears based on the backup gear shifter:

[0102] First, in the case that the backup gear shifter is the 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, obtaining the target position of the turn signal switch of the vehicle.

[0104] Among them, 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 of turning on the right turn signal of the vehicle, the second position is the position of turning on the left turn signal of the vehicle, and the third position is the position of not turning on the right and left turn signals of the vehicle. It can be understood 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 dialing to control the turning on / off of the turn signal of the vehicle.

[0106] Regarding the method by which the vehicle controller obtains 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 Control Module (BCM) or the turn signal controller. This application embodiment does not limit this method.

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

[0108] Specifically, developers can pre-store a correspondence table between the current position of the turn signal switch, i.e., the target position, and the vehicle's gear signal in the vehicle controller. After the vehicle controller obtains the current target position of the vehicle's turn signal switch, it can determine the vehicle's gear signal according to the pre-set correspondence table.

[0109] For example, the correspondence between the current target position of the vehicle's turn signal switch and the vehicle's gear position signal can be shown in Table 1 below:

[0110] Table 1

[0111] Target position Gear 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 the target position of the vehicle's turn signal switch as the first position, it can determine the forward gear signal as the vehicle's gear signal according to Table 1 and the first position; when the vehicle controller obtains the target position of the vehicle's turn signal switch as the second position, it can determine the reverse gear signal as the vehicle's gear signal according to Table 1 and the first position; when the vehicle controller obtains the target position of the vehicle's turn signal switch as the third position, it can determine the neutral gear signal 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 vehicle's gear position signal, it can send the gear position signal to the transmission controller, so that the transmission controller can control the transmission to switch gears according to the gear position signal, thereby achieving the purpose of shifting gears in the vehicle.

[0115] In this embodiment, the target position of the vehicle's turn signal switch can be correlated with the vehicle's gear position signal. In the case where the backup gear shifter is the vehicle's turn signal switch, the vehicle's gear position signal can be determined by obtaining the current target position of the vehicle's turn signal switch. Based on the gear position signal, the vehicle can be controlled to shift gears, so as to ensure that the vehicle meets the driver's shifting needs without changing the vehicle hardware.

[0116] The second method, where the backup gear shifter is the vehicle's windshield wiper switch, involves the following specific steps for controlling the vehicle to shift gears based on the windshield wiper switch:

[0117] Step 1: Obtain the current target setting of the vehicle's windshield wiper switch.

[0118] The target speeds include intermittent brushing, low-speed brushing, and high-speed brushing.

[0119] It's important to note that different wiper switch settings cause the vehicle's wipers to oscillate at different frequencies. Specifically, when the target setting is intermittent wiping, the wipers will oscillate at a first frequency threshold; when the target setting is low-speed wiping, the wipers will oscillate at a second frequency threshold; and when the target setting is high-speed wiping, the wipers will oscillate at a third frequency threshold. The second frequency threshold is higher than the first, and the third frequency threshold is higher than the second. In other words, as you sequentially adjust the wiper switch from intermittent to high-speed wiping, the oscillation frequency of the wipers increases. Understandably, the wiper switch is usually located on the steering column, and the driver can adjust the wiper setting by tossing or turning it, thus controlling the vehicle's wiping.

[0120] Regarding the method by which the vehicle controller obtains the target gear position of the windshield wiper switch: the vehicle controller can obtain the target gear position of the windshield wiper switch through components such as the Body Control Module (BCM) or the windshield wiper switch controller. This application embodiment does not limit this method.

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

[0122] Specifically, developers can pre-store a correspondence table between the current gear position of the windshield wiper switch, i.e., the target gear position, and the vehicle's gear position signal in the vehicle controller. This allows the vehicle controller to determine the vehicle's gear position signal based on the pre-set correspondence table after obtaining the target gear position of the vehicle's windshield wiper switch.

[0123] For example, the correspondence between the current target gear position of the vehicle's windshield wiper switch and the vehicle's gear position signal can be shown in Table 2 below:

[0124] Table 2

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

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

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

[0128] The implementation method for step three can be referred to the above embodiments, and will not be repeated here.

[0129] In this embodiment, the target gear position of the vehicle's windshield wiper switch can be correlated with the vehicle's gear position signal. This allows the vehicle's gear position signal to be determined by acquiring the target gear position of the windshield wiper switch when the backup gear shifter is the vehicle's windshield wiper switch. Based on the gear position signal, the vehicle can be controlled to shift gears, thus ensuring that the vehicle meets the driver's shifting needs without changing the vehicle's hardware.

[0130] In summary, the vehicle gear control method provided in this application can activate a backup gear shifter when the vehicle enters limp mode (a vehicle mode where the vehicle's shifting function is restricted) due to an electronic gear shifter malfunction. Once activated, the restriction on the vehicle's shifting function is lifted, and the vehicle can then be controlled to shift gears based on the backup gear shifter. This satisfies the driver's shifting needs and avoids the situation where the vehicle cannot meet the driver's shifting requirements when it enters limp mode due to an electronic gear shifter malfunction. The backup gear shifter can be the vehicle's turn signal switch or windshield wiper switch, ensuring that the vehicle meets the driver's shifting needs without altering the vehicle's hardware.

[0131] In one possible implementation, when the backup shifter is activated, its original control functions can be disabled. Specifically, if the backup shifter is activated and functions as the vehicle's turn signal switch, the turn signal switch should not be allowed to control the vehicle's turn signals. Similarly, if the backup shifter is activated and functions as the vehicle's windshield wiper switch, the windshield wiper switch should not be allowed to control the vehicle's windshield wipers. This avoids situations where retaining the original control functions when the backup shifter (turn signal switch / windshield wiper switch) is activated would lead to conflicts between the vehicle's control systems, thus affecting the normal operation of the vehicle.

[0132] In addition, when the backup gear shifter is activated, the vehicle controller can turn on the vehicle's hazard warning lights (also known as the vehicle's double flashers) to alert other road users (such as other drivers and pedestrians) that the vehicle is in an abnormal state, thereby increasing their awareness of the vehicle and prompting them to take evasive action in time, thus improving the vehicle's driving safety.

[0133] It should be noted that, in the embodiments of this application, when the vehicle controller determines that the vehicle has exited the limp mode, that is, when the vehicle controller determines that the electronic shifter malfunction of the vehicle has been eliminated, the backup shifter (the vehicle's turn signal switch / the vehicle's windshield wiper switch) can be activated so that the vehicle's turn signal switch / the vehicle's windshield wiper switch can be restored to its original control function.

[0134] Figure 3 This is a schematic diagram of the structure of a vehicle gear control device provided in an embodiment of this application.

[0135] For example, such as Figure 3 As shown, the device 300 includes:

[0136] Activation module 301 is used to activate the backup shifter when the vehicle enters limp mode due to electronic shifter failure. Limp mode refers to a vehicle mode in which the vehicle's shifting function is restricted.

[0137] Release module 302 is used to release the restriction on the vehicle's shifting function when the backup shifter is activated;

[0138] Control module 303 is used to control the vehicle to shift gears based on the backup gear shifter.

[0139] In one possible implementation, the backup gear shifter is the vehicle's turn signal switch; the device also includes an acquisition module for acquiring the target position of the vehicle's turn signal switch; a determination module for determining the gear position signal of the vehicle corresponding to the target position; and a control module specifically for controlling the vehicle to shift gears based on the gear position signal.

[0140] In one possible implementation, the determining module is specifically used to determine the forward gear signal as the vehicle's gear signal when the target position is a first position, and the first position is the position where the vehicle's right turn signal is turned on; when the target position is a second position, the determining module is used to determine the reverse gear signal as the vehicle's gear signal, and the second position is the position where the vehicle's left turn signal is turned on; when the target position is a third position, the determining module is used to determine the neutral gear signal as the vehicle's gear signal, and the third position is the position where the vehicle's right and left turn signals are not turned on.

[0141] In one possible implementation, the backup gear shifter is the vehicle's windshield wiper switch; the acquisition module is also used to acquire the target gear position currently held by the vehicle's windshield wiper switch; the determination module is also used to determine the gear position signal of the vehicle corresponding to the target gear position; and the control module 303 is specifically used to control the vehicle to shift gears based on the gear position signal.

[0142] In one possible implementation, the determining module is further configured to: determine the forward gear signal as the vehicle's gear signal when the target gear is the intermittent wiping gear, where the intermittent wiping gear indicates that the vehicle's windshield wipers are oscillating at a first frequency threshold; determine the neutral gear signal as the vehicle's gear signal when the target gear is the low-speed wiping gear, where the low-speed wiping gear indicates that the vehicle's windshield wipers are oscillating at a second frequency threshold, which is greater than the first frequency threshold; and determine the reverse gear signal as the vehicle's gear signal when the target gear is the high-speed wiping gear, where the high-speed wiping gear indicates that the vehicle's windshield wipers are oscillating at a third frequency threshold, which is greater than the second frequency threshold.

[0143] In one possible implementation, the device further includes an output module for outputting a first prompt message when the vehicle enters limp mode due to an electronic shifter malfunction. The first prompt message is used to prompt whether to switch to the backup shifter. The activation module 301 is specifically used to activate the backup shifter when it is determined that the vehicle has switched to the backup shifter.

[0144] In one possible implementation, the device further includes a detection module for detecting whether the current gear of the vehicle is consistent with the current gear of the backup gear shifter when the vehicle enters limp mode due to an electronic gear shifter malfunction; an output module for outputting a second prompt message when the current gear of the vehicle is inconsistent with the current gear of the backup gear shifter, the second prompt message prompting adjustment of the current gear of the backup gear shifter to make the current gear of the backup gear shifter consistent with the current gear of the vehicle; and an activation module 301 for activating the backup gear shifter when the current gear of the vehicle is consistent with the current gear of the backup gear shifter.

[0145] In one possible implementation, the device further includes a blocking module for preventing the vehicle's turn signal switch from controlling the vehicle's turn signals when the backup shifter is activated and the backup shifter is the vehicle's turn signal switch; and for preventing the vehicle's windshield wiper switch from controlling the vehicle's windshield wipers when the backup shifter is activated and the backup shifter is the vehicle's windshield wiper switch. The control module 303 is also specifically used to activate the vehicle's hazard warning lights.
