Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a vehicle transportation control method, device and vehicle. Background Art

[0002] With the rapid development of the automobile industry, hard-core off-road vehicles have made rapid progress in reliability, comfort, and intelligence, surpassing many old automobile companies. More and more domestic and foreign users like off-road vehicles. The current mode of transportation for automobile exports is mainly by sea or land. During transportation, the vehicle tires need to be fixed to ensure the safety of vehicle transportation.

[0003] At present, triangular wooden wedges are used to fix the four wheels during transportation, and metal nails are used to fix the wooden wedges to the floor of the transport vehicle (ship / train) to ensure the stability of the vehicle. Because hard-core off-road vehicles use a transfer case that can rigidly lock the front and rear drive shafts, the 4H / 4L mode of the electronically controlled transfer case rigidly connects the front and rear output shafts of the transfer case through a chain. In the 4H / 4L mode, the front and rear drive shafts of the vehicle are rigidly locked and the tires are fixed.

[0004] However, when the logistics personnel of the vehicle transfer use the vehicle's 4H / 4L mode for transportation, the transportation is violently bumpy, resulting in the force generated by the vehicle's transmission system being unable to be released to the outside and can only be consumed inside the transmission system components, causing internal damage to the transmission system components, and ultimately leading to damage to the components, further causing transportation losses and affecting the reliable transportation of the vehicle.

[0067] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0068] The first embodiment of the present invention relates to a vehicle transportation control method, see Figure 1 , shows a flow chart of the steps of a vehicle transportation control method provided by an embodiment of the present invention, the vehicle transportation control method comprising the following steps:

[0069] Step 101, acquiring the current environment of the vehicle, and monitoring the transportation mode signal of the vehicle; wherein the current environment includes a detection environment and a transportation environment.

[0070] In the embodiment of the present invention, since the 4H mode and 4L mode of the electronic control transfer case (Electronic Control Transfer Case) rigidly connect the front and rear output shafts of the transfer case through a chain, in order to solve the problem that when the logistics personnel of the vehicle transfer use the 4H / 4L mode of the vehicle for transportation, the transmission system parts will generate internal damage, resulting in damage to the parts and causing transportation losses, this embodiment controls the transportation mode and the four-wheel drive 4H / 4L mode to be unable to be activated at the same time, thereby avoiding the problem that the 4H / 4L mode during vehicle transportation causes internal damage to the transmission system parts, resulting in damage to the parts. Through intelligent transportation mode switching control, the transportation process can be automatically optimized according to the current driving conditions and transportation environment, thereby greatly reducing the loss of vehicle parts during transportation and improving the safety and reliability of vehicle transportation.

[0071] It should be noted that the present embodiment is applied to a vehicle type equipped with a transfer case for realizing rigid locking of the front and rear drive shafts. The electronically controlled transfer case is a key component for four-wheel drive vehicles, and is used to distribute power between the front and rear axles. The electronically controlled transfer case realizes power distribution through an electronic control system, and can automatically or manually adjust the power distribution ratio between the front and rear axles. A variety of drive modes are usually provided, and the drive modes include two-wheel drive mode, four-wheel drive mode and all-wheel drive mode, among which the two-wheel drive mode includes a 2H mode (two-wheel drive high-speed mode), and the four-wheel drive mode includes a 4H mode (four-wheel drive high-speed mode) and a 4L mode (four-wheel drive low-speed mode). Specifically, in the 4H mode, the front and rear axles of the vehicle are connected through the transfer case, and the drive shafts are not rigidly connected. In the 4L mode, the front and rear axles of the vehicle are rigidly connected through the transfer case, and there is no differential effect between the drive shafts, and all wheels rotate at the same speed.

[0072] Specifically, the vehicle's four-wheel drive controller (Four-Wheel Drive Controller), also known as a 4WD controller, is usually integrated with the vehicle's electronic control unit (ECU) to determine how to distribute the engine's power to the front and rear wheels by receiving data from various sensors. In this embodiment, the vehicle's four-wheel drive controller obtains the vehicle's current environment, and monitors the vehicle's transportation mode signal; wherein the current environment includes a detection environment and a transportation environment, wherein the detection environment is a scene of vehicle production line detection, which may be a scene of a vehicle rolling off the assembly line in the main engine plant's internal assembly workshop, and the transportation environment is a scene of a transportation vehicle, which may be a scene of a transportation port where the vehicle is transferred from the main engine plant, and the transportation mode signal may include a transportation mode inactivation signal and a transportation mode activation signal.

[0073] In this embodiment, the four-wheel drive controller obtains the current environment of the vehicle through the on-board camera or positioning radar to determine the current environment of the vehicle. In addition, the four-wheel drive controller can monitor the transport mode signal input by the driver through the buttons on the center console or steering wheel. It should be noted that when the vehicle is powered on, the tester on the production line can activate the transport mode by pressing the button on the steering wheel.

[0074] Specifically, in this embodiment, the four-wheel drive controller can use an on-board camera to collect the vehicle's surrounding environment information, use the surrounding environment information to determine the vehicle's current environment, and monitor the vehicle's transportation mode signal when the vehicle is powered on; wherein the transportation mode signal includes a transportation mode activation signal and a transportation mode deactivation signal.

[0075] Step 102 , when the vehicle is in the detection environment and the transport mode is detected to be activated, if the current driving mode of the vehicle is the target four-wheel drive mode, the vehicle is controlled to exit the target four-wheel drive mode.

[0076] In an embodiment of the present invention, when the four-wheel drive controller determines that the vehicle is in a detection environment and monitors that the transport mode is activated, the current driving mode of the vehicle is judged. If the current driving mode of the vehicle is a target four-wheel drive mode, the vehicle is controlled to exit the target four-wheel drive mode, wherein the driving modes include a two-wheel drive mode, a four-wheel drive mode and an all-wheel drive mode. The target four-wheel drive mode is a mode in which the front and rear drive shafts are rigidly locked, resulting in internal consumption of transmission system components during transportation and resulting in transportation damage. In this embodiment, the target four-wheel drive mode is specifically described as a 4H / 4L mode.

[0077] Specifically, when the vehicle is in a detection environment and the activated transport mode is detected, the current driving mode of the vehicle is obtained, and the driving mode includes at least one of a target four-wheel drive mode, an all-wheel drive mode, and a two-wheel drive mode; if the current driving mode of the vehicle is the target four-wheel drive mode, the vehicle is controlled to exit the target four-wheel drive mode, and the vehicle can be controlled to switch to the all-wheel drive mode or the two-wheel drive mode, and a mode switching prompt message is generated for the user to view.

[0078] In this embodiment, if it is determined that the current driving mode of the vehicle is 4H / 4L mode, the vehicle is controlled to exit 4H / 4L mode. In some embodiments, if it is determined that the current driving mode of the vehicle is not 4H / 4L mode, and the transport mode signal TranPMode_Sts = 0x1: Transport Mode is monitored, that is, when the transport mode is activated, the four-wheel drive controller can maintain the current mode and can switch between 2H mode and AWD mode.

[0079] Step 103 : when the vehicle is in a transportation environment and the transportation mode is activated, if a switching request to the target four-wheel drive mode is received, the vehicle is controlled not to respond to the switching request.

[0080] In an embodiment of the present invention, when the vehicle is in a transportation environment and the transportation mode is activated, if the four-wheel drive controller receives a switching request for the target four-wheel drive mode, the vehicle is controlled not to respond to the switching request. Specifically, when the vehicle is in a transportation environment and the transportation mode is activated, a control operation of switching the driving mode by the user is detected, a mode switching request is received, and if the mode switching request is to switch to the target four-wheel drive mode, the vehicle is controlled not to respond to the switching request.

[0081] Specifically, when the vehicle is in a transportation environment, that is, in a scenario of a vehicle being transferred from the main plant to the export, and the transportation mode has been activated, since logistics personnel may switch to 4H / 4L mode when transferring the vehicle, 4H / 4L and transportation modes may be activated at the same time, and there is a risk of damage to the transmission system during transportation; this embodiment utilizes the strategy of the four-wheel drive controller to reject user requests to enter the 4H / 4L mode, specifically through the on-board camera to identify the scene, when the vehicle is at the port / train station, when the four-wheel drive controller detects the transportation mode signal TranPMode_Sts= 0x1: Transport Mode, that is, the transportation mode activation signal, and the vehicle is powered on, when the user switches the mode to 4H / 4L mode through the switch, the transportation mode strategy is triggered, the system refuses to switch, and the instrument information prompts "Refuse to enter 4H / 4L mode", the vehicle maintains the current mode, and can switch between 2H mode and AWD mode.

[0082] The vehicle transportation control method provided by the embodiment of the present invention obtains the current environment of the vehicle and monitors the transportation mode signal of the vehicle. When the vehicle is in a detection environment and the activated transportation mode is detected, if the current driving mode of the vehicle is a target four-wheel drive mode, the vehicle is controlled to exit the target four-wheel drive mode. When the vehicle is in a transportation environment and the transportation mode is activated, if a switch request for the target four-wheel drive mode is received, the vehicle is controlled not to respond to the switch request. In the embodiment of the present invention, when the vehicle starts to be transported and the transport mode is activated, the four-wheel drive actively exits the target four-wheel drive mode, i.e., the 4H / 4L mode; when the transport mode is already activated and a request to switch to the 4H / 4L mode is received, the response to the switching request is refused; a logical judgment is made based on whether the transport mode and the 4H / 4L mode are activated, thereby ensuring that the transport mode and the four-wheel drive 4H / 4L mode cannot be activated at the same time, thereby avoiding the problem that the 4H / 4L mode during vehicle transportation causes internal damage to transmission system components, resulting in damage to components; the reliability of the vehicle mode during transportation is ensured; unsupported mode switching requests are automatically rejected; and the transportation process can be automatically optimized according to the current driving conditions and transportation environment through intelligent transport mode switching control, thereby greatly reducing the loss of vehicle components during transportation and improving the safety and reliability of vehicle transportation.

[0083] Further, see Figure 2 , showing Figure 1 The flowchart of step 101 of the vehicle transportation control method provided is substantially the same as the vehicle transportation control method provided in the first embodiment of the present invention. Step 101 includes:

[0084] Step 201, using a vehicle-mounted camera to collect the surrounding environment information of the vehicle, and using the surrounding environment information to determine the current environment of the vehicle; wherein the current environment includes a detection environment and a transportation environment.

[0085] Step 202 : When the vehicle is powered on, monitor the transport mode signal of the vehicle; wherein the transport mode signal includes a transport mode activation signal and a transport mode deactivation signal.

[0086] It should be noted that in the embodiment of the present invention, when the vehicle is started and powered on, the four-wheel drive controller starts to work, uses the vehicle-mounted camera to collect the surrounding environment information of the vehicle, uses the surrounding environment information to determine whether the current environment of the vehicle is a detection environment or a transportation environment, and the four-wheel drive controller monitors the driver or the automatic system's selection operation of the transportation mode, such as through the center console button, steering wheel control or automatic mode switching. If the transportation mode control operation is monitored, the four-wheel drive controller will collect the corresponding transportation mode signal, which is usually from the output of the control button, switch or automatic mode selector. The four-wheel drive controller processes and identifies the collected transportation mode signal to determine the specific content of the signal, and determines whether the received signal is a transportation mode activation signal or a transportation mode inactivation signal based on the identification result. In some embodiments, if the transportation mode activation signal is identified, the four-wheel drive controller will adjust the power distribution of the vehicle according to a preset program to adapt to the selected transportation mode; if the transportation mode inactivation signal is identified, the system may return to the default power distribution setting, which will not be repeated here.

[0087] It should be noted that, in this embodiment, the transport mode activation signal indicates that the driver or the system has selected a specific transport mode, such as 4H or 4L mode; the transport mode inactivation signal indicates that no specific transport mode is currently selected, or the system returns to the default mode, such as 2H mode or AWD mode. Specifically, after the OEM completes all vehicle offline inspections, before the vehicle is handed over to the logistics department, it is necessary to set the vehicle to enter the transport mode. The transport mode signal is mainly determined by the following command identification: TranPMode_Sts = 0x0: Normal Mode is used to indicate that the transport mode is inactive; TranPMode_Sts = 0x1: Transport Mode is used to indicate that the transport mode is activated, and the transport mode signal value can be displayed on the dashboard for the user to confirm and view.

[0088] The embodiments of the present invention can accurately determine whether the vehicle is in the detection mode or the transport mode by identifying the current environment of the vehicle and monitoring the transport mode signal under the current vehicle environment, and determine whether the transport mode is activated according to the transport mode signal, so as to control the driving mode of the vehicle and ensure that the transport mode and the 4H / 4L mode of the vehicle cannot be activated at the same time in the transport scenario.

[0089] Specifically, step 201 uses a vehicle-mounted camera to collect the surrounding environment information of the vehicle, and uses the surrounding environment information to determine the current environment of the vehicle; wherein the current environment includes a detection environment and a transportation environment, and specifically may include the following steps:

[0090] Preprocess the surrounding environment information of the vehicle collected by the vehicle-mounted camera to obtain the target environment image;

[0091] Identify the target environment image to obtain an environment identifier in the target environment image;

[0092] The environment identifier is compared with a preset environment identifier to determine whether the current environment of the vehicle is a detection environment or a transportation environment.

[0093] It should be noted that in the above steps, the original image or video captured by the vehicle-mounted camera is processed to improve the accuracy of subsequent recognition. The preprocessing includes denoising, image enhancement, cropping, rotation and other operations to ensure the quality and consistency of the target environment image. The preprocessed image is analyzed to identify specific signs or features in the image. The environmental sign can be a sign, color, shape, text, etc. of a specific environment, which can indicate whether the current environment is a detection environment or a transportation environment. The identified environmental sign is compared with the pre-stored environmental signs. The preset environmental signs are standardized signs or features, which correspond to the detection environment and the transportation environment, respectively. The current environment of the vehicle is determined based on the comparison results. If the identified sign matches the preset detection environment sign, the current environment is determined to be the detection environment; if it matches the preset transportation environment sign, the current environment is determined to be the transportation environment.

[0094] In some embodiments, the four-wheel drive controller can use laser radar, millimeter wave radar, etc. to collect environmental data around the vehicle. The environmental data includes information such as the distance, speed, and direction of objects around the vehicle. The collected raw radar data is preprocessed to remove noise, and useful environmental features are extracted from the preprocessed radar data. The environmental features include the shape, distance, relative position, etc. of specific objects in the environment. There will be specific buildings or signs in the detection environment, and there will be road boundaries, transportation tools, etc. in the transportation environment. The identified environmental features are compared with preset environmental identification. Based on the comparison results, the four-wheel drive controller determines the current environment of the vehicle. If the identified features match the preset detection environment identification, the current environment is determined to be the detection environment; if it matches the preset transportation environment identification, the current environment is determined to be the transportation environment.

[0095] Specifically, step 202 monitors the transport mode signal of the vehicle when the vehicle is powered on; wherein the transport mode signal includes a transport mode activation signal and a transport mode inactivation signal, and specifically may include the following steps:

[0096] First, when the vehicle is powered on, in response to monitoring the transport mode control operation, a transport mode signal of the vehicle is collected;

[0097] Secondly, the transport mode signal is identified to determine whether the transport mode signal is a transport mode activation signal or a transport mode deactivation signal.

[0098] It should be noted that in the above steps, after the vehicle is started and powered on, the driver or the automatic system continuously monitors the selection operation of the transport mode, monitors the transport mode control operation through the center console button, steering wheel control or automatic mode switching, collects the corresponding transport mode signal, processes and identifies the collected transport mode signal, and determines whether the received signal is a transport mode activation signal or a transport mode inactivation signal based on the identification result. If the transport mode activation signal is identified, the four-wheel drive control system will adjust the vehicle's power distribution according to the preset program to adapt to the selected transport mode; if the transport mode inactivation signal is identified, the system will return to the default power distribution setting.

[0099] The embodiment of the present invention identifies whether the transport mode is activated by performing signal recognition on the transport mode signal of the vehicle, thereby accurately determining whether the vehicle is in the detection mode or the transport mode, and determining whether the transport mode is activated based on the transport mode signal to facilitate subsequent control of the vehicle's driving mode.

[0100] Further, see Figure 3 , showing Figure 1 The flowchart of step 102 of the vehicle transportation control method provided is substantially the same as the vehicle transportation control method provided in the first embodiment of the present invention. Step 102 includes:

[0101] Step 301 : when the vehicle is in a detection environment and the transport mode is detected to be activated, the current driving mode of the vehicle is obtained.

[0102] Wherein, the driving mode includes at least one of a target four-wheel drive mode, an all-wheel drive mode, and a two-wheel drive mode;

[0103] Step 302: If the current driving mode of the vehicle is the target four-wheel drive mode, control the vehicle to exit the target four-wheel drive mode.

[0104] Step 303, controlling the vehicle to switch to an all-wheel drive mode or a two-wheel drive mode, and generating a mode switching prompt message.

[0105] It should be noted that in the embodiment of the present invention, when the vehicle is in the detection environment and the driver or the system is detected to have activated the transport mode, the system will obtain the current driving mode of the vehicle. In this embodiment, the current driving mode includes at least one of the target four-wheel drive mode, the all-wheel drive mode, and the two-wheel drive mode. The target four-wheel drive mode is 4H or 4L mode. When the vehicle enters the target four-wheel drive mode during transportation, it will cause transportation losses. Therefore, if the system detects that the current driving mode of the vehicle is the target four-wheel drive mode, the system will execute an instruction to exit the mode.

[0106] Specifically, the system can control the vehicle to exit the current target four-wheel drive mode by controlling the transfer case or other related actuators. After exiting the target four-wheel drive mode, the system will control the vehicle to switch to all-wheel drive mode (AWD) or two-wheel drive mode (2H). After completing the mode switch, the system will generate a mode switch prompt message, which can be used to inform the driver through the indicator light on the vehicle dashboard, text prompts on the display screen, or sound prompts.

[0107] The embodiment of the present invention controls the vehicle to exit the target four-wheel drive mode 4H / 4L mode in the transportation scenario, thereby ensuring that the transportation mode and the 4H / 4L mode cannot be activated at the same time under vehicle transportation conditions, avoiding the problem of transmission system damage caused by the 4H / 4L mode during transportation, and ensuring reliable transportation of the vehicle.

[0108] Specifically, step 301, when the vehicle is in a detection environment and the transport mode is detected to be activated, after obtaining the current driving mode of the vehicle, further includes: if the current driving mode of the vehicle is the all-wheel drive mode or the two-wheel drive mode, controlling the vehicle to maintain the current driving mode.

[0109] Further, see Figure 4 , showing Figure 1 The flowchart of step 103 of the vehicle transportation control method provided is substantially the same as the vehicle transportation control method provided in the first embodiment of the present invention. Step 103 includes:

[0110] Step 401: When the vehicle is in a transportation environment and the transportation mode is activated, a control operation of switching the driving mode by a user is detected, and a mode switching request is received.

[0111] Step 402: If the mode switching request is to switch to the target four-wheel drive mode, the vehicle is controlled not to respond to the switching request.

[0112] In an embodiment of the present invention, when the vehicle is in a transportation environment and the current transportation mode has been activated, the system will continuously monitor the driver's operation. If the system detects the driver's driving mode switching operation performed through the center console, steering wheel or other control devices, once the driver's switching operation is detected, the system will receive a mode switching request, judge the received mode switching request, and determine whether the mode switching request is to switch to a target four-wheel drive mode, the target four-wheel drive mode refers to a 4H or 4L four-wheel drive mode. If the mode switching request is to switch to the target four-wheel drive mode, and the current environment is a transportation environment, the system will control the vehicle not to respond to the switching request, and perform a logical judgment between the activation or not of the transportation mode and the four-wheel drive 4H / 4L mode, thereby realizing a control strategy in which the transportation mode and the four-wheel drive 4H / 4L mode cannot be activated at the same time, thereby avoiding the activation of the 4H / 4L mode during transportation, and the risk of damage to the transmission system.

[0113] The embodiments of the present invention control the vehicle not to respond to a request to switch to a target four-wheel drive mode when the vehicle is in a transportation environment, thereby ensuring that under transportation conditions, the vehicle will not respond to a driver's request to switch to the target four-wheel drive mode, thereby avoiding problems of parts damage when the vehicle is in 4H or 4L mode during transportation, and ensuring that when the transportation mode is activated and the vehicle is in a transportation environment, the transportation mode and the four-wheel drive 4H / 4L mode cannot be activated at the same time.

[0114] Specifically, if the mode switching request is to switch to the target four-wheel drive mode, step 402 may further include: controlling the vehicle to switch to an all-wheel drive mode or a two-wheel drive mode, and generating a mode switching prompt message after controlling the vehicle not to respond to the switching request.

[0115] It should be noted that, in the embodiment of the present invention, a mode switching request is received from a driver or an automatic system, and it is determined whether the request is to switch to a target four-wheel drive mode. If the request is to switch to a target four-wheel drive mode, and the current environment does not require this mode, the vehicle is controlled not to respond to the switching request. After not responding to the switching request to the target four-wheel drive mode, the vehicle can be automatically controlled to switch to an all-wheel drive mode (AWD) or a two-wheel drive mode (2H). After completing the mode switching, the system will generate a mode switching prompt message to inform the driver through the indicator light on the instrument panel, the text prompt on the display screen, or the sound prompt.
