[0033] Under the above operating environment, the embodiment of the present invention provides the following Figure 2 The vehicle control method shown, Figure 2 is a flow chart of a vehicle control method according to an embodiment of the present invention. Figure 2 As shown, the method includes the following implementation steps:

[0034] Step S201, obtaining the load information, real-time speed and gear information of the target vehicle, wherein the target vehicle is a six-wheel standard load freight vehicle;

[0035] Step S202: Controlling the target vehicle to switch to a target driving mode according to the load information, the real-time vehicle speed, and the gear information, wherein the target driving mode is one of the following: a four-wheel drive mode and a two-wheel drive mode;

[0036] Step S203 : adjusting the connection state of the through bridge of the target vehicle based on the target driving mode.

[0037] The above method steps provided in the embodiment of the present invention are used to control a six-wheel standard load freight vehicle to switch between four-wheel drive mode and two-wheel drive mode. While switching the drive mode, the connection status of the vehicle's through bridge can also be adjusted according to the target drive mode.

[0038] It should be noted that the above vehicle control method can be run on a target vehicle to continuously monitor load information, real-time vehicle speed, and gear information, providing continuous drive mode switching for the target vehicle. In other words, through the above method steps, a through-axle time-sharing drive mechanism can be implemented for a six-wheel standard-load freight vehicle, controlling the target vehicle to switch between four-wheel drive mode (hereinafter referred to as 6×4 mode) and two-wheel drive mode (hereinafter referred to as 6×2 mode).

[0039] In an embodiment of the present invention, load information, real-time speed, and gear information of a target vehicle are obtained, wherein the target vehicle is a six-wheel standard load freight vehicle; based on the load information, real-time speed, and gear information, the target vehicle is controlled to switch to a target drive mode, wherein the target drive mode is one of the following: a four-wheel drive mode and a two-wheel drive mode; and the connection state of the through-bridge of the target vehicle is adjusted based on the target drive mode. Thus, the present invention achieves the purpose of controlling the target vehicle to switch drive modes based on the vehicle's load information, real-time speed, and gear information, thereby achieving the technical effect of improving the accuracy of drive mode switching decisions and enhancing vehicle safety and economy. This further solves the technical problem in the related art that solutions that make drive mode switching decisions based solely on road condition information have low accuracy, resulting in poor vehicle safety and economy.

[0040] The above method of the embodiment of the present invention is further introduced below.

[0041] Optionally, the target vehicle is equipped with an axle load sensor; in the above step S201, obtaining the load information of the target vehicle may further include the following execution steps:

[0042] Step S211, receiving a load signal from an axle load sensor;

[0043] Step S212: parse the load signal to obtain load information.

[0044] In one application scenario, the target vehicle adopts Figure 3 As shown in the system architecture. Figure 3 As shown, the target vehicle is equipped with an axle load sensor, a speed sensor, and a transmission gear position sensor. The axle load sensor measures the target vehicle's real-time load and generates a load signal. The speed sensor generates a speed signal, which is used to determine the target vehicle's real-time speed. The transmission gear position sensor generates a gear position signal, which is used to determine the target vehicle's real-time gear position.

[0045] The above-described method steps provided in the embodiments of the present invention can be executed on a vehicle controller of a target vehicle. After receiving the load signal, vehicle speed signal, and gear position signal, the vehicle controller parses the load signal to obtain load information, the vehicle speed signal to obtain real-time vehicle speed, and the gear position signal to obtain gear position information (e.g., real-time gear position, gear shift information, etc.).

[0046] Still like Figure 3 As shown, the parsed load information, real-time vehicle speed, and gear position information are transmitted to the axle on / off determination component. This component determines the on / off strategy for the through-bridge based on the target drive mode and sends the strategy to the axle on / off control component, which then controls the middle and rear axles in the through-bridge according to the strategy. Furthermore, the axle on / off control component controls the middle and rear axles by controlling the pneumatic drive component to connect or disconnect the middle and rear axles. This in turn drives the internal on / off controller of the rear axle to connect or disconnect the corresponding left and right wheels from the rear axle reducer.

[0047] Optionally, the vehicle control method further includes: in response to a shutdown instruction of the target vehicle, controlling the driving mode of the target vehicle to switch to a four-wheel drive mode and controlling the target vehicle to shut down, and the driving mode of the target vehicle when starting is the four-wheel drive mode.

[0048] According to the above method steps, during the process of controlling the driving mode switching of the target vehicle, the present invention controls the target vehicle to switch to the 6×4 mode before the target vehicle is turned off, so that the target vehicle can obtain sufficient power when starting again.

[0049] It should be noted that the vehicle is in 6×4 mode when starting, the middle bridge and rear axle of the through bridge of the target vehicle are connected, and the left wheel and right wheel corresponding to the rear axle are connected.

[0050] Optionally, in step S202, controlling the target vehicle to switch to the target driving mode according to the load information, the real-time vehicle speed, and the gear information may further include the following execution steps:

[0051] Step S221, determining a target driving mode to be switched based on load information, real-time vehicle speed, gear information, a preset load threshold, and multiple preset vehicle speed thresholds;

[0052] Step S222: Control the target vehicle to switch to the target driving mode.

[0053] According to the aforementioned optional execution steps of the present invention, a load threshold and multiple speed thresholds are pre-set based on the application scenario requirements and the model of the target vehicle. Furthermore, after real-time monitoring of load information, real-time vehicle speed, and gear information, a target driving mode to be switched is determined based on the load information, real-time vehicle speed, gear information, the preset load threshold, and the preset multiple speed thresholds, so as to control the target vehicle to switch to the target driving mode.

[0054] Optionally, in step S221, determining the target driving mode to be switched based on the load information, the real-time vehicle speed, the gear information, the preset load threshold, and the preset multiple speed thresholds may further include the following execution steps:

[0055] Step S2211, selecting a first target threshold from multiple vehicle speed thresholds based on the load information and the load threshold;

[0056] Step S2212, in response to the real-time vehicle speed being less than or equal to the first target threshold, determining that the target driving mode is the four-wheel drive mode;

[0057] Step S2213 , in response to the real-time vehicle speed being greater than the first target threshold and the target vehicle being determined to be in an upshift state according to the gear information, determining the target driving mode to be the two-wheel drive mode.

[0058] Optionally, the multiple vehicle speed thresholds include, from large to small, a first vehicle speed threshold, a second vehicle speed threshold, a third vehicle speed threshold, and a fourth vehicle speed threshold.

[0059] Optionally, selecting the first target threshold from the plurality of vehicle speed thresholds according to the load information and the load threshold comprises: determining the load of the target vehicle according to the load information; in response to the load being greater than the load threshold, setting the first target threshold to a first vehicle speed threshold; in response to the load being less than or equal to the load threshold, setting the first target threshold to a third vehicle speed threshold;

[0060] Optionally, based on the load information and the load threshold, selecting the second target threshold from multiple vehicle speed thresholds includes: determining the load weight based on the load information; in response to the load weight being greater than the load threshold, setting the second target threshold to the second vehicle speed threshold; in response to the load weight being less than or equal to the load threshold, setting the second target threshold to the fourth vehicle speed threshold.

[0061] Optionally, after determining that the target driving mode is a two-wheel drive mode, adjusting the connection status of the through bridge of the target vehicle according to the target driving mode may also include the following execution steps: controlling the middle bridge and the rear axle in the through bridge to be disconnected, and controlling the multiple wheels corresponding to the rear axle to be disconnected from the reducer of the target vehicle.

[0062] Optionally, after the target vehicle switches to a two-wheel drive mode, the vehicle control method further includes: selecting a second target threshold from a plurality of vehicle speed thresholds based on the load information and the load threshold, wherein the first target threshold is greater than the second target threshold; in response to the real-time vehicle speed being greater than or equal to the second target threshold and determining that the target vehicle is in an upshift state based on the gear information, controlling the target vehicle to maintain a two-wheel drive mode; in response to the real-time vehicle speed being less than the second target threshold and determining that the target vehicle is not in an upshift state based on the gear information, controlling the target vehicle to switch to a four-wheel drive mode, and controlling a plurality of wheels corresponding to the rear axle in the through bridge to establish a connection with the reducer of the target vehicle.

[0063] Optionally, while the target vehicle maintains a two-wheel drive mode, adjusting the connection status of the through-bridge of the target vehicle according to the target drive mode includes: in response to the real-time vehicle speed being less than a first target threshold and the real-time vehicle speed being greater than or equal to a second target threshold, keeping the middle bridge and the rear bridge in the through-bridge disconnected; in response to the real-time vehicle speed being less than the second target threshold, controlling the middle bridge and the rear bridge to establish a connection; in response to the real-time vehicle speed being greater than or equal to the first target threshold, controlling the middle bridge to disconnect.

[0064] According to the above method steps, a method is provided in the application scenario. Figure 4 The schematic diagram of the vehicle control logic is shown in Figure 2. Figure 4 As shown. After receiving the sensor signal (for example, including the load signal, the vehicle speed signal and the gear signal), the load information, the real-time vehicle speed and the gear information are parsed and obtained (not shown in the figure). Further, it is determined whether the load of the vehicle is greater than t (that is, the load threshold). If the load is greater than t, the first target threshold is set to the first speed threshold (denoted as V1), and the second target threshold is set to the second speed threshold (denoted as V2). If the load is less than or equal to t, the first target threshold is set to the third speed threshold (denoted as V3), and the second target threshold is set to the fourth speed threshold (denoted as V4).

[0065] It should be noted that the above-mentioned first vehicle speed threshold V1 is greater than the second vehicle speed threshold V2, and the difference between the first vehicle speed threshold V1 and the second vehicle speed threshold V2 is not less than 3 km / h, the second vehicle speed threshold V2 is greater than the third vehicle speed threshold V3, and the difference between the second vehicle speed threshold V2 and the third vehicle speed threshold V3 is greater than 10 km / h, the third vehicle speed threshold V3 is greater than the fourth vehicle speed threshold V4, and the difference between the third vehicle speed threshold V3 and the fourth vehicle speed threshold V4 is not less than 3 km / h.

[0066] It should be noted that, according to the requirements of the application scenario, after setting the load threshold t, if the load weight of the target vehicle is greater than t, the target vehicle is considered to be fully loaded; if the load weight of the target vehicle is less than or equal to t, the target vehicle is considered to be half loaded or empty.

[0067] Still like Figure 4 As shown, on the one hand, when the load is greater than t, it is determined whether the real-time vehicle speed is greater than V1 (i.e., the first target threshold). If the real-time vehicle speed is less than or equal to V1, it is considered that the target vehicle currently does not have the conditions to switch to 6×2 mode, and the 6×4 mode is still maintained. If the real-time vehicle speed is greater than V1, it is considered that the target vehicle currently has the conditions to switch to high-speed driving, the adhesion between the target vehicle and the ground is low, and the target vehicle's driving torque demand is small. It is considered that the target vehicle currently has the conditions to switch to 6×2 mode. It is further determined whether the transmission is shifted up. If the transmission is shifted up, it means that the driver of the target vehicle currently has a subjective acceleration intention. At this time, the target vehicle is controlled to disconnect the middle axle and the rear axle when shifting gears, and the drive mode is switched from 6×4 mode to 6×2 mode.

[0068] In the above application scenario, the following Figure 5 A schematic diagram of the hardware architecture of a target vehicle is shown, as shown in Figure 5 As shown, the target vehicle's center axle is connected to the first and second wheels, and the center axle reducer corresponding to the center axle includes a center-rear axle connection controller. The target vehicle's rear axle is connected to the third and fourth wheels, and the rear axle reducer corresponding to the rear axle includes a rear axle internal on / off controller.

[0069] It should be noted that when the drive mode is switched to 6×2 mode, the center and rear axle connection controller and the rear axle internal on-off controller operate, the center axle is disconnected from the rear axle, and the corresponding left and right wheels of the rear axle are disconnected from the rear axle reducer. At this time, the rear axle of the drive axle completely serves as a load-bearing axle, and since the corresponding left and right wheels of the rear axle are disconnected from the reducer, the reverse drag energy loss can be reduced. Therefore, switching the target vehicle to 6×2 mode can reduce fuel consumption.

[0070] Furthermore, after the target vehicle's drive mode is switched from 6×4 to 6×2, continuous monitoring is performed to determine whether the real-time vehicle speed is less than V2. If the real-time vehicle speed is greater than or equal to V2, the target vehicle's drive mode remains in 6×2 mode, with both the center and rear axles of the drive axle disconnected. If the real-time vehicle speed is less than V2, the center and rear axles are connected, but the corresponding left and right wheels of the rear axle remain disconnected from the speed reducer. At this point, the target vehicle is ready to switch its drive mode to 6×4, but the drive mode remains in 6×2 mode.

[0071] Furthermore, if the transmission continues to upshift at this time, it means that the driver of the target vehicle still intends to accelerate and the 6×2 mode is maintained until the real-time vehicle speed exceeds V1. At this time, the target vehicle's drive mode remains in 6×2 mode, the middle axle is disconnected, and the process of monitoring whether the real-time vehicle speed is less than V2 is switched. If the transmission is not in an upshift state (such as holding the gear or downshifting), it is considered that the target vehicle is on a non-high-speed road section (such as climbing a hill, a bumpy road, etc.) or in a creeping stop state. At this time, the target vehicle is controlled to keep the rear axle connected during the gear shift, and the drive mode is switched from 6×2 mode to 6×4 mode. At this time, the left and right wheels corresponding to the rear axle are connected to the rear wheel reducer.

[0072] Still like Figure 4 As shown, when the load is less than or equal to t, the target vehicle is considered half-loaded or unloaded. At this time, the target vehicle's drive torque demand is low, allowing the 6×2 mode to be used in more driving scenarios and saving fuel consumption. The target vehicle's drive mode control logic in this case can refer to the control logic when the load is greater than t. However, in this control logic, the first target threshold is V1 and the second target value is V2. In contrast, when the load is less than or equal to t, the first target threshold is V3 and the second target value is V4.

[0073] It should be noted that when the load is less than or equal to t, and the real-time vehicle speed is monitored to be less than V4, it is considered that the target vehicle is in a condition tending to stop (such as a creeping condition or a climbing condition, etc.). At this time, the drive mode of the target vehicle is controlled to switch to 6×4 mode to provide the target vehicle with more sufficient power to overcome the above-mentioned condition tending to stop.

[0074] It should be noted that, in an embodiment of the present invention, a real-time acceleration signal of the vehicle can also be obtained. On this basis, in the above vehicle control process, determining whether the transmission is shifting up can be replaced by determining whether the real-time acceleration is greater than zero.

[0075] Through the above steps provided by the embodiment of the present invention, the load requirements, energy-saving and environmental protection requirements, road safety driving requirements, tire management requirements, vehicle maintenance requirements and driving comfort requirements in the application scenario can be achieved.

[0076] Specifically, the vehicle's driving mode is flexibly adjusted to enhance its load capacity and meet load requirements under different road and engineering conditions. For example, under heavier road conditions, the vehicle is controlled to adopt a 6×4 mode to improve traction and stability; under lighter road conditions, the vehicle is controlled to adopt a 6×2 mode to reduce fuel consumption and tire wear.

[0077] Specifically, when it is necessary to save fuel and reduce emissions, the vehicle's driving mode can be switched to achieve the goal of balancing driving needs and achieving energy conservation and environmental protection, that is, meeting energy conservation and environmental protection needs.

[0078] Specifically, the vehicle's driving mode is adjusted to improve its road-survivability and safety under different road conditions. For example, on steep mountain roads, the vehicle is controlled to adopt a 6×4 mode to increase traction and stability; on flat highways, the vehicle is controlled to adopt a 6×2 mode to reduce drag and fuel consumption. In other words, it meets the requirements for safe driving on all roads.

[0079] Specifically, by flexibly switching the vehicle's driving mode, tire wear can be reduced and the tire's service life can be extended, thus meeting tire management requirements.
