Description

Technical Field

[0001] This application relates to the field of automotive technology, specifically to vehicle chassis protection plate control methods, devices, equipment, storage media, and vehicles. Background Technology

[0002] With the rapid development of automotive technology, car structures have become increasingly sophisticated. To protect internal components such as the engine, a chassis skid plate is typically installed under the engine to reduce its contact with the external environment. This reduces corrosion from mud, rain, and snow, as well as friction between the engine and the ground, extending the engine's lifespan. In automotive technology, to prevent scrapes caused by an excessively low chassis skid plate, a specific device can be used to adjust the height of one end of the skid plate via a cable, thus controlling its position.

[0003] However, the aforementioned methods primarily rely on electric struts to control the underbody protection plate. During high-speed driving, this control method is relatively simplistic and creates a vacuum area at the end of the plate, increasing wind resistance and fuel consumption. Therefore, current underbody protection plate control efficiency is relatively poor. Summary of the Invention

[0004] This application provides a method, apparatus, device, storage medium, and vehicle for controlling a vehicle chassis underbody protection plate, to at least solve the technical problem of poor control efficiency of chassis underbody protection plates in related technologies. The technical solution of this application is as follows:

[0005] According to a first aspect of this application, a method for controlling a vehicle chassis skid plate is provided. The vehicle includes multiple chassis skid plates, the hardness of which is less than a preset hardness threshold. The method includes: acquiring operating parameters of a target vehicle, the operating parameters indicating the vehicle body status information during driving, the vehicle body status information including at least one of the following: tire pressure, turning speed, and engine temperature; and controlling the chassis skid plates of the target vehicle to bend based on the operating parameters of the target vehicle.

[0006] Based on the aforementioned technical means, this application can control the chassis skid plates of the target vehicle by acquiring the vehicle's operating parameters and, based on these parameters, controlling the bending of the skid plates. Furthermore, it can achieve flexible control of the skid plates based on the vehicle's operating parameters across multiple skid plates, thereby improving control efficiency through precise control.

[0007] In one possible implementation, the chassis guard plate includes a fixed end and a sliding end, and the hardness of the chassis guard plate varies at different locations; controlling the chassis guard plate of the target vehicle to bend includes: controlling the sliding end of the chassis guard plate to move closer to the fixed end, so that the chassis guard plate bends.

[0008] Based on the above-mentioned technical means, this application can achieve flexible control of the bending of the chassis guard plate based on the fixed end and the sliding end of the chassis guard plate, and achieve control of bending deformation by making the hardness of different positions of the chassis guard plate different, so as to improve the accuracy of the bending control of the chassis guard plate and improve the control efficiency of the chassis guard plate.

[0009] In one possible implementation, the target vehicle includes multiple tires. Based on the operating parameters of the target vehicle, the chassis guard plate of the target vehicle is controlled to bend, including: for any one of the multiple tires, determining a first pressure of any one tire, and determining a target difference between the initial pressure of any one tire and the first pressure, wherein the initial pressure is the pressure of any one tire when the target vehicle speed is zero; when it is determined that the target difference is greater than a first threshold within a preset time period, the chassis guard plate corresponding to any one tire is controlled to bend.

[0010] Based on the above technical means, this application can control the chassis guard plate corresponding to the tire to bend when the difference between the tire pressure and the initial pressure of the tire is greater than a first threshold, so as to increase the air flow speed between the chassis and the ground in the direction of the tire, increase the friction between the tire and the ground, avoid the safety hazards caused by excessive tire pressure, improve the safety of vehicle driving, and improve the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0011] In one possible implementation, controlling the chassis guard plate of the target vehicle to bend based on the operating parameters of the target vehicle includes: determining the steering wheel of the target vehicle; and controlling the chassis guard plate corresponding to the steering wheel of the target vehicle to bend when the turning speed of the target vehicle is greater than a second threshold.

[0012] Based on the above technical means, this application can control the chassis guard plate corresponding to the steering wheel of the target vehicle to bend when the turning speed of the target vehicle is greater than the second threshold, thereby increasing the air flow speed between the vehicle chassis and the ground, so as to avoid safety hazards caused by excessive turning speed, improve the safety of vehicle driving, and improve the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0013] In one possible implementation, based on the operating parameters of the target vehicle, the chassis guard plate of the target vehicle is controlled to bend, including: when the engine temperature is greater than a third threshold, the chassis guard plate corresponding to the engine is controlled to bend so as to cool the engine by means of wind speed.

[0014] Based on the above technical means, this application can control the chassis guard plate corresponding to the engine to bend when the temperature of the vehicle's engine is greater than the third threshold, thereby increasing the airflow speed between the engine and the ground, so as to cool the engine through wind speed, avoid safety hazards caused by excessive engine temperature, improve the safety of vehicle driving, and improve the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0015] In one possible implementation, the method further includes: acquiring road condition information of the target vehicle during its driving process, and determining whether there are obstacles on the road in the direction of travel of the target vehicle based on the road condition information; if there are obstacles on the road in the direction of travel of the target vehicle, and the height of the obstacles is greater than a fourth threshold, controlling the chassis guard plate of the target vehicle to bend.

[0016] Based on the aforementioned technical means, this application can obtain road condition information of the target vehicle during its driving process, and when there is an obstacle in the direction of the target vehicle's driving and the height of the obstacle is greater than a fourth threshold, control the target vehicle's chassis guard plate to bend, so as to absorb the collision energy generated when the vehicle collides with the obstacle through the bent chassis guard plate, thereby reducing the collision damage to the vehicle, improving the safety of vehicle driving, and improving the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0017] According to a second aspect of this application, a vehicle chassis skid plate control device is provided. The vehicle includes multiple chassis skid plates, the hardness of which is less than a preset hardness threshold. The vehicle chassis skid plate control device includes: an acquisition unit and a control unit; the acquisition unit is used to acquire operating parameters of the target vehicle, the operating parameters being used to indicate the vehicle body status information of the target vehicle during driving, the vehicle body status information including at least one of the following: tire pressure, turning speed, and engine temperature; the control unit is used to control the chassis skid plates of the target vehicle to bend based on the operating parameters of the target vehicle.

[0018] In one possible implementation, the chassis guard plate includes a fixed end and a sliding end, and the hardness of the chassis guard plate varies at different locations; the control unit is also used to control the sliding end of the chassis guard plate to move closer to the fixed end, so that the chassis guard plate bends.

[0019] In one possible implementation, the target vehicle includes multiple tires, and the vehicle chassis guard plate control device further includes: a determining unit; the determining unit is configured to determine a first pressure of any one of the multiple tires, and determine a target difference between the initial pressure of any one tire and the first pressure, wherein the initial pressure is the pressure of any one tire when the target vehicle speed is zero; and a control unit is configured to control the chassis guard plate corresponding to any one tire to bend when the target difference is determined to be greater than a first threshold within a preset time period.

[0020] In one possible implementation, the vehicle chassis guard plate control device further includes: a determining unit; the determining unit is used to determine the steering wheel of the target vehicle; and a control unit is used to control the chassis guard plate corresponding to the steering wheel of the target vehicle to bend when the turning speed of the target vehicle is greater than a second threshold.

[0021] In one possible implementation, the control unit is also configured to control the chassis guard plate corresponding to the engine to bend when the engine temperature is greater than a third threshold, so as to cool the engine by means of wind speed.

[0022] In one possible implementation, the acquisition unit is further configured to acquire road condition information of the target vehicle during its driving process, and determine whether there are obstacles on the road in the direction of travel of the target vehicle based on the road condition information; the control unit is further configured to control the chassis guard plate of the target vehicle to bend when there are obstacles on the road in the direction of travel of the target vehicle and the height of the obstacles is greater than a fourth threshold.

[0023] According to a third aspect of this application, an electronic device is provided, comprising: a processor; a memory for storing processor-executable instructions; wherein the processor is configured to execute instructions to implement the method of the first aspect described above and any possible implementation thereof.

[0024] According to a fourth aspect of this application, a computer-readable storage medium is provided, which, when executed by a processor of an electronic device, enables the electronic device to perform the methods described in the first aspect and any possible implementation thereof.

[0025] According to the fifth aspect of this application, a vehicle is provided for implementing the method of the first aspect described above and any possible implementation thereof.

[0026] According to a sixth aspect of this application, a computer program product is provided, the computer program product including computer instructions that, when executed on an electronic device, cause the electronic device to perform the method described in the first aspect and any possible implementation thereof.

[0027] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0028] (1) By acquiring the operating parameters of the target vehicle and controlling the bending of the chassis guard plate based on these operating parameters, the chassis guard plate of the target vehicle can be controlled. Furthermore, based on multiple chassis guard plates of the target vehicle, flexible control of the chassis guard plates based on the vehicle's operating parameters can be achieved, thereby improving the control efficiency of the chassis guard plates through precise control.

[0029] (2) Based on the fixed end and sliding end of the chassis guard plate, flexible control of the bending of the chassis guard plate can be realized. By making the hardness of different positions of the chassis guard plate different, the bending deformation can be controlled, thereby improving the accuracy of the bending control of the chassis guard plate and improving the control efficiency of the chassis guard plate.

[0030] (3) When the difference between the tire pressure and the initial pressure of the tire is greater than the first threshold, the chassis guard plate corresponding to the tire can be bent to increase the air flow speed between the chassis and the ground in the direction of the tire, increase the friction between the tire and the ground, avoid the vehicle safety hazards caused by excessive tire pressure, improve the safety of vehicle driving, and improve the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0031] (4) When the turning speed of the target vehicle is greater than the second threshold, the chassis guard plate corresponding to the steering wheel of the target vehicle can be bent to increase the air flow speed between the vehicle chassis and the ground, so as to avoid the safety hazards caused by the excessive turning speed, improve the safety of vehicle driving, and improve the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0032] (5) When the temperature of the vehicle's engine exceeds the third threshold, the chassis guard plate corresponding to the engine can be bent to increase the air flow speed between the engine and the ground, so as to cool the engine by wind speed, avoid safety hazards caused by excessive engine temperature, improve the safety of vehicle driving, and improve the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0033] (6) By acquiring road condition information of the target vehicle during its driving process, and when there is an obstacle in the direction of the target vehicle's driving and the height of the obstacle is greater than the fourth threshold, the chassis guard plate of the target vehicle is controlled to bend so as to absorb the collision energy generated when the vehicle collides with the obstacle through the bent chassis guard plate, thereby reducing the collision damage to the vehicle and improving the safety of the vehicle's driving. Furthermore, the control efficiency of the chassis guard plate is improved through precise control of the chassis guard plate.

[0034] It should be noted that the technical effects of any of the implementation methods in aspects two through six can be found in the technical effects of the corresponding implementation methods in aspect one, and will not be repeated here.

[0054] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0055] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0056] Currently, as vehicles become increasingly intelligent, users are demanding more customized functions from their vehicle keys. Traditional vehicle keys primarily function as door unlockers, door lockers, trunk doors, and remote vehicle starters, or, via buttons, as window regulators and sunshades. However, their overall functionality remains relatively limited, mainly offering traditional vehicle control features and failing to meet users' needs for customized entertainment and customization.

[0057] The vehicle chassis guard plate control method provided in this application embodiment can be applied to the vehicle chassis guard plate control system. Figure 1 A schematic diagram of one structure of the vehicle's chassis underbody protection control system is shown. Figure 1 As shown, the vehicle chassis protection plate control system 10 includes: an information acquisition module 11, a chassis protection plate 12, a motor 13, and an on-board system 14.

[0058] The vehicle chassis protection plate control system 10 can be used for the Internet of Things. The vehicle chassis protection plate control system 10 (such as information acquisition module 11, motor 13, vehicle system 14, etc.) may include multiple central processing units (CPUs), multiple memories, storage devices storing multiple operating systems, and other hardware.

[0059] The information acquisition module 11 is used to acquire vehicle operating parameters, such as vehicle operating conditions (e.g., driving speed, engine temperature), environmental conditions (e.g., air temperature, road conditions), and vehicle tire pressure.

[0060] For example, such as Figure 1 As shown, the information acquisition module 11 may include a pressure sensor, a temperature sensor, a speed sensor, an inductive radar, an image acquisition device (such as a camera), etc.

[0061] Specifically, pressure sensors can be used to obtain tire pressure information, temperature sensors can be used to obtain engine temperature and ambient temperature, and radar and image acquisition devices can be used to obtain road conditions and other information.

[0062] The chassis guard plate 12 is used to protect the vehicle chassis. In this embodiment, the hardness of the chassis guard plate can be less than a preset hardness threshold, i.e., an elastic guard plate, such as a chassis guard plate made of spring steel strip.

[0063] For example, such as Figure 2 As shown, multiple spring steel strips can be used to wrap the vehicle chassis.

[0064] It should be noted that, Figure 2 The markings indicate the specific location of the underbody protection plate within the vehicle. RB indicates the right rear of the vehicle; LB indicates the left rear of the vehicle; RC indicates the right center of the vehicle; LC indicates the left center of the vehicle; RF indicates the right front of the vehicle; LF indicates the left front of the vehicle; and E indicates the location of the vehicle's engine (battery).

[0065] It should be noted that when using spring steel strips as chassis skid plates, the vehicle load can also be reduced, thereby reducing vehicle energy consumption.

[0066] The motor 13 is connected to the chassis guard plate 12 and is used to control the bending of the chassis guard plate 12.

[0067] Optionally, different chassis guard plates can be connected to different motors to achieve flexible control of the chassis guard plates.

[0068] Optionally, motor 13 can be a servo motor and connected to chassis guard plate 12 via a traction cable, so that the chassis guard plate can be bent by the motor driving the traction cable.

[0069] Optionally, the motor 13 can be connected to the vehicle system 14, receive control parameters sent by the vehicle system 14, and control the chassis guard plate 12 to bend based on the control parameters.

[0070] The vehicle system 14 is connected to the information acquisition module 11 and is used to receive the vehicle's operating parameters sent by the information acquisition module 11, and to parse the vehicle's operating parameters to determine the chassis guard plate 12 that needs to be controlled and the control parameters.

[0071] The vehicle system 14 is also connected to the motor 13 to send control parameters to the motor 13 corresponding to the chassis guard plate 12 that needs to be controlled, so as to control the chassis guard plate 12 through the motor 13.

[0072] For example, such as Figure 3 As shown, after the vehicle starts, the information acquisition module 11 collects the vehicle's operating parameters, such as pressure sensor data, front radar data, front image data, and under-vehicle radar data, and reports these operating parameters to the vehicle system 14 in real time. The vehicle system 14 analyzes these operating parameters in real time to determine whether it is necessary to control the chassis skid plate to bend.

[0073] Furthermore, when the vehicle system 14 determines that a portion of the chassis guard plate needs to be bent, it sends control parameters (control commands) to the motor 13 corresponding to that portion of the chassis guard plate. After receiving the control parameters, the motor 13 controls the chassis guard plate to bend.

[0074] Optionally, the in-vehicle system 14 can also transmit alarm information, prompts, etc. to users (such as drivers) via voice or in-vehicle screen.

[0075] For ease of understanding, the vehicle chassis protection plate control method provided in this application will be described in detail below with reference to the accompanying drawings.

[0076] Figure 4 This is a flowchart illustrating a vehicle chassis skid plate control method according to an exemplary embodiment. The vehicle includes multiple chassis skid plates, and the hardness of the chassis skid plates is less than a preset hardness threshold, such as... Figure 4 As shown, the vehicle chassis skid plate control method includes the following S201-S202:

[0077] S201. Obtain the operating parameters of the target vehicle.

[0078] Among them, the operating parameters are used to indicate the vehicle body status information of the target vehicle during driving. The vehicle body status information includes at least one of the following: tire pressure, turning speed, and engine temperature.

[0079] Optionally, the operating parameters of the target vehicle can be acquired through sensors.

[0080] For example, the tire pressure of the target vehicle is obtained through a pressure sensor; the turning speed of the target vehicle is obtained through a speed sensor; and the engine temperature of the target vehicle is obtained through a temperature sensor.

[0081] Specifically, pressure sensors can be connected to each suspension of the vehicle to record the current pressure (i.e., tire pressure) on each suspension.

[0082] It should be noted that the hardness of the chassis guard plate is less than the preset hardness threshold, which can be understood as the chassis guard plate having a certain degree of elasticity. For example, the chassis guard plate can be made of materials such as spring steel strips, so that the chassis guard plate can achieve elastic deformation when subjected to force.

[0083] For example, multiple spring steel strips can be used to wrap the entire vehicle chassis, making the chassis skid plate lighter than ordinary metal skid plates, thereby reducing the vehicle load.

[0084] S202. Based on the operating parameters of the target vehicle, control the chassis guard plate of the target vehicle to bend.

[0085] Optionally, the operating parameters of the target vehicle can be analyzed to determine various status information of the target vehicle, and then the corresponding chassis guard plate can be controlled to bend based on the various status information.

[0086] For example, the tire pressure of the target vehicle can be analyzed to determine whether the pressure of each tire of the target vehicle is normal. When the pressure of a certain tire is abnormal (such as low pressure), the chassis guard plate corresponding to that tire can be bent to control the airflow speed near the tire, so as to neutralize the abnormal tire pressure and improve vehicle driving safety.

[0087] In this embodiment, the operating parameters of the target vehicle can be obtained, and based on these parameters, the chassis skid plates of the target vehicle can be bent to achieve control over the chassis skid plates. Furthermore, based on multiple chassis skid plates of the target vehicle, flexible control of the chassis skid plates based on the vehicle's operating parameters can be achieved, improving control efficiency through precise control of the chassis skid plates.

[0088] In some embodiments, the chassis guard plate includes a fixed end and a sliding end. The hardness of different locations on the chassis guard plate varies. To improve the accuracy of bending control of the chassis guard plate and thus improve the control efficiency, such as... Figure 5 As shown, in the vehicle chassis guard plate control method provided in this application embodiment, the "controlling the chassis guard plate of the target vehicle to bend" in S202 above also includes S301:

[0089] S301. Control the sliding end of the chassis guard plate to approach the fixed end, so that the chassis guard plate bends.

[0090] Optionally, the structure of the chassis guard plate can be as follows: Figure 6 The chassis guard plate shown is combined with Figure 6 End A can be the fixed end of the chassis guard plate, and end B can be the sliding end of the chassis guard plate.

[0091] It should be noted that, in combination Figure 7 Because different parts of the chassis guard plate have different hardness, i.e., different elasticity, when subjected to force, the degree of deformation will also differ due to the difference in hardness, thus forming irregular arcs (such as...). Figure 7 As shown in the diagram, where A is the vehicle chassis, B is the chassis guard plate, and the arrow indicates the direction of airflow. Due to the presence of this irregular arc, even when the vehicle is traveling at high speed, a vacuum area will not be formed on the leeward side, thereby reducing wind resistance and energy consumption during vehicle operation.

[0092] And, as Figure 7 As shown, when air flows by, the presence of the irregular arc prevents a vacuum period from forming at the rear (i.e., the right end of the arc), thereby reducing wind resistance during vehicle movement, lowering fuel consumption, and providing downward grip for the vehicle.

[0093] Specifically, a slide rail can be installed on the vehicle chassis, the fixed end of the chassis guard plate is fixed to the slide rail, and the sliding end of the chassis guard plate is connected to the slide rail and can slide on the slide rail, thereby allowing the chassis guard plate to bend.

[0094] For example, the sliding end of the chassis guard plate can be connected to a traction cable (e.g., Figure 8 As shown in the figure, the chassis guard plate is bent by the motor driving the traction line.

[0095] Specifically, in combination Figure 8 This allows one end of the traction cable to be connected to the sliding end of the chassis guard plate, and the other end ( Figure 8 The underbody protection plate is connected to a motor (such as a servo motor) at point O. The motor drives the traction cable based on parameters sent by the vehicle system, thereby controlling the bending of the underbody protection plate.

[0096] Optionally, different chassis guard plates can be connected to different motors, meaning that the chassis guard plates can be flexibly controlled.

[0097] In this embodiment, flexible control of the bending of the chassis guard plate is achieved based on the fixed end and the sliding end of the chassis guard plate. By making the hardness of different positions of the chassis guard plate different, the bending deformation is controlled, thereby improving the accuracy of the bending control of the chassis guard plate and improving the control efficiency of the chassis guard plate.

[0098] In some embodiments, the target vehicle includes multiple tires to avoid safety hazards caused by excessive tire pressure, such as... Figure 9 As shown, in the vehicle chassis guard plate control method provided in this application embodiment, the above-mentioned S202 includes S401-S402:

[0099] S401. For any one of the multiple tires, determine the first pressure of any tire, and determine the target difference between the initial pressure and the first pressure of any tire.

[0100] The initial pressure is the pressure corresponding to any tire when the target vehicle's speed is zero.

[0101] Optionally, the method for obtaining the first pressure can be referred to the description in section S201 above, and will not be repeated here.

[0102] Optionally, after the vehicle is started, the tire pressure information can be monitored in real time by a pressure sensor, and the pressure of the tire when the vehicle has not started moving (i.e. the vehicle speed is 0) can be marked as the initial pressure, denoted as Fn (n is used to identify the tire).

[0103] S402. When the target difference is determined to be greater than the first threshold within a preset time period, control the chassis guard plate corresponding to any tire to bend.

[0104] Optionally, after the vehicle starts running (starts), the pressure information (i.e., the first pressure F'n) can be transmitted to the vehicle system in real time through the pressure sensor. When the vehicle system determines that F'n < Fn and the difference between F'n and Fn is greater than the first threshold, it can be considered that the pressure of tire n is significantly less than the normal pressure (i.e., the initial pressure).

[0105] It should be noted that if this phenomenon continues for a period of time, that is, the continuous time meets the preset duration, it can be determined that the air velocity on the upper surface of the vehicle is greater than the air velocity on the lower surface (such as the air velocity when the vehicle is driving at high speed). At this time, due to the effect of atmospheric pressure, the vehicle will experience a "floating" phenomenon during driving, that is, the tires are prone to slipping.

[0106] Optionally, in conjunction with the description at S301 above, by controlling the bending of the chassis guard plate corresponding to the tire, the airflow velocity on the lower surface can be increased, thereby increasing the friction between the tire and the ground.

[0107] It should be noted that the chassis guard plate corresponding to the tire can be understood as the chassis guard plate at the location of that tire, such as the chassis guard plate that is right next to the tire.

[0108] Optionally, the first threshold and the preset duration can be determined and changed according to specific usage requirements, combined with expert experience and experimental statistical data.

[0109] Optionally, the chassis skid plate corresponding to the tire can be one or multiple, depending on the usage requirements and application scenarios (such as tire size and chassis skid plate size).

[0110] In this embodiment, when the difference between the tire pressure and the initial tire pressure is greater than a first threshold, the chassis guard plate corresponding to the tire is controlled to bend, thereby increasing the airflow speed between the chassis and the ground in the direction of the tire, increasing the friction between the tire and the ground, avoiding safety hazards caused by excessive tire pressure, improving vehicle driving safety, and improving the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0111] In some embodiments, to avoid safety hazards caused by excessive turning speed, such as Figure 10 As shown, in the vehicle chassis guard plate control method provided in this application embodiment, the above-mentioned S202 includes S501-S502:

[0112] S501. Determine the steering wheels of the target vehicle.

[0113] It should be noted that steering wheels can be understood as the control wheels (steering wheels) that control the vehicle's steering, such as the front wheels (the two wheels at the front of the vehicle). The specific meaning needs to be determined in conjunction with the vehicle's steering working principle.

[0114] S502. When the turning speed of the target vehicle is greater than the second threshold, control the chassis guard plate corresponding to the steering wheel of the target vehicle to bend.

[0115] It should be noted that when the vehicle's turning speed is too fast (greater than the second threshold), if the vehicle's acceleration wheels and steering wheels are not aligned, such as the vehicle's acceleration wheels being the rear wheels and steering wheels being the front wheels, the vehicle may experience "understeer" due to the excessively high turning speed (i.e., the rear wheels have a higher power speed), affecting the accuracy of the turning direction and leading to safety hazards.

[0116] Optionally, the vehicle's turning speed can be acquired in real time by a speed sensor and sent to the on-board system. The on-board system then determines whether the vehicle's turning speed is greater than a second threshold. When the turning speed is determined to be greater than the second threshold, the chassis guard plate corresponding to the vehicle's steering wheel is bent by controlling the motor.

[0117] Optionally, in conjunction with the description at S301 above, by controlling the bending of the chassis guard plate corresponding to the steering wheel, the airflow velocity on the lower surface of the steering wheel can be increased, thereby increasing the friction between the vehicle's steering wheel and the ground and preventing the vehicle from "understeer".

[0118] It should be noted that the chassis guard plate corresponding to the steering wheel can be understood as the chassis guard plate at the location of that steering wheel, such as the chassis guard plate that is adjacent to that steering wheel.

[0119] Optionally, the second threshold can be determined and changed based on specific usage requirements, combined with expert experience and experimental statistical data.

[0120] Optionally, the chassis skid plate corresponding to the steering wheel can be one or multiple, depending on the specific usage requirements and application scenarios (such as the size of the steering wheel and the size of the chassis skid plate).

[0121] In this embodiment of the application, when the turning speed of the target vehicle is greater than the second threshold, the chassis guard plate corresponding to the steering wheel of the target vehicle is controlled to bend, thereby increasing the airflow speed between the vehicle chassis and the ground, so as to avoid safety hazards caused by excessive turning speed, improve the safety of vehicle driving, and improve the control efficiency of the chassis guard plate through precise control of the chassis guard plate.

[0122] In some embodiments, to avoid vehicle safety hazards caused by excessively high engine temperatures, such as... Figure 11 As shown, in a vehicle chassis underbody protection plate control method provided in this application embodiment, the above-mentioned S202 includes S601:

[0123] S601. When the engine temperature exceeds the third threshold, control the corresponding chassis guard plate of the engine to bend so as to cool the engine through wind speed.

[0124] Optionally, the engine temperature can be acquired in real time by a temperature sensor and sent to the vehicle system. The vehicle system determines whether the engine temperature is greater than a third threshold. When the engine temperature is determined to be greater than the third threshold, the chassis guard plate corresponding to the engine is bent by controlling the motor.

[0125] Optionally, the chassis skid plate corresponding to the engine can be bent, or the chassis skid plate corresponding to the engine can be moved downward in the vertical direction to increase the airflow speed between the engine and the corresponding chassis skid plate, thereby achieving heat dissipation for the engine.

[0126] Optionally, the chassis guard plate corresponding to the engine can be bent to create a gap between the chassis guard plate and the engine chassis, thereby increasing the airflow velocity between the engine and the corresponding chassis guard plate to achieve heat dissipation for the engine. The specific bending method can be designed according to the usage requirements.

[0127] For example, in combination Figure 12 The vertical structure of the chassis guard plate is as follows: Figure 12 As shown, the four vertices of the chassis guard plate ( Figure 12 The two vertices at one end of the chassis guard plate are connected to the vehicle chassis via a transmission component (such as a telescopic bracket). When the on-board system determines that the engine temperature is greater than the third threshold, the transmission component can be extended (stretched) by controlling the motor, so that the chassis guard plate moves downward (closer to the ground) in the vertical direction, thereby increasing the airflow speed between the engine and the chassis guard plate and achieving engine cooling.

[0128] It should be noted that, in Figure 12 In the diagram, A represents the vehicle chassis, the arrow indicates the vertical direction, the solid line structure is the chassis guard plate before bending, and the dashed line structure is the chassis guard plate after bending (after extension / retraction).

[0129] It should be noted that the chassis skid plate corresponding to the engine can be understood as the chassis skid plate at the location of the engine, such as the chassis skid plate that is right next to the engine.

[0130] Optionally, the third threshold can be determined and changed based on specific usage requirements, combined with expert experience and experimental statistical data.

[0131] Optionally, the chassis skid plate corresponding to the engine can be one or multiple, depending on the usage requirements and application scenarios (such as engine size and chassis skid plate size).

[0132] It should be noted that in related technologies, the main method to improve engine cooling capacity is to add air ducts to the vehicle's underbody protection plate. However, in this method, the air ducts operate continuously to cool the engine regardless of the driving environment, resulting in high energy consumption. Furthermore, the presence of the air ducts reduces the distance between the underbody protection plate and the ground, further increasing the probability of friction, scraping, or even collision between the underbody protection plate and the ground, thus compromising vehicle safety.

[0133] In this embodiment, when the temperature of the vehicle's engine exceeds a third threshold, the chassis guard plate corresponding to the engine is controlled to bend, increasing the airflow speed between the engine and the ground. This cools the engine through wind speed, preventing safety hazards caused by excessive engine temperature and improving vehicle driving safety. Furthermore, precise control of the chassis guard plate improves the control efficiency of the chassis guard plate.

[0134] In some embodiments, in order to reduce collision damage to the vehicle, such as Figure 13 As shown, the vehicle chassis guard plate control method provided in this application embodiment further includes S701-S702:

[0135] S701. Obtain road condition information of the target vehicle during its driving process, and determine whether there are obstacles on the road in the direction of the target vehicle's driving based on the road condition information.

[0136] Optionally, a ground-sensing radar can be installed at the front of the vehicle to obtain real-time road condition information during driving, such as the unevenness of the road surface within a certain distance ahead, thereby determining whether there are obstacles.

[0137] Optionally, a camera (such as a wide-angle camera) can be installed at the front of the vehicle to further distinguish obstacle information, such as determining the size and shape of the obstacle.

[0138] Optionally, a sensor radar can be installed on the bottom of the vehicle to detect the splashing of obstacles such as sludge, mud, sand, rain, and snow. The vehicle system can then determine the size of the obstacles (such as concentration and quantity) in real time and send an alarm message to the user when the size of the obstacles reaches a certain threshold.

[0139] S702. If there is an obstacle on the road in the direction of travel of the target vehicle, and the height of the obstacle is greater than the fourth threshold, control the chassis guard plate of the target vehicle to bend.

[0140] It should be noted that the road in the direction the vehicle is traveling can be understood as the section of road ahead of the vehicle during its journey, that is, the section of road the vehicle is about to reach.

[0141] Optionally, when the height of an obstacle is greater than the fourth threshold, it can be assumed that the obstacle may scrape the vehicle chassis (collide with the vehicle). In this case, the vehicle's chassis guard plate can be bent to absorb the collision energy and reduce the damage to the vehicle.

[0142] Optionally, when the vehicle system determines that there is an obstacle in the direction of the vehicle's travel and the height of the obstacle is greater than the fourth threshold, the chassis guard plate at the corresponding position of the obstacle (i.e. the chassis guard plate that the obstacle may hit if the vehicle continues to travel) can be bent by controlling the motor. Alternatively, the chassis guard plates at all positions can be bent by controlling the motor. The specific method can be determined based on the usage requirements.

[0143] Specifically, in combination Figure 14 and Figure 15 When the vehicle system detects an obstacle ahead, and the height of that obstacle exceeds the fourth threshold, it can use a motor to control the corresponding underbody protection plate to bend, thereby absorbing collision energy through the bent underbody protection plate (e.g., Figure 15 (As shown).

[0144] It should be noted that, in Figure 14 , Figure 15 In the diagram, A represents the vehicle chassis, B represents the chassis skid plate, the triangle represents an obstacle, and the arrow indicates the vehicle's direction of travel.

[0145] Optionally, the fourth threshold can be determined based on specific usage requirements and application scenarios (such as chassis height).

[0146] For example, the fourth threshold could be the height between the chassis guard plate and the ground.

[0147] In some embodiments, the sensing radar can process and statistically feed back information about the underside of the vehicle (such as road conditions and collision information) to the driver (e.g., send the information to the in-vehicle intelligent computer and display warning information), so that the driver can comprehensively judge the current road conditions and further plan the driving speed and route.

[0148] In this embodiment, by acquiring road condition information of the target vehicle during its driving process, and when there is an obstacle in the direction of the target vehicle's driving and the height of the obstacle is greater than a fourth threshold, the chassis guard plate of the target vehicle is controlled to bend, so as to absorb the collision energy generated when the vehicle collides with the obstacle through the bent chassis guard plate, thereby reducing the collision damage to the vehicle, improving the safety of vehicle driving, and improving the control efficiency of the chassis guard plate through precise control of the chassis guard plate.
