Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a vehicle control method, device, storage medium, and processor. Background Art

[0002] When heavy-duty vehicles like trucks, buses, and work vehicles, as well as military vehicles like tanks, travel on extremely bumpy roads, their heavy weight, rapid speed fluctuations, and high acceleration generate significant inertial forces and impact energy, which in turn exert impact loads on components. This is particularly true for truck cranes, which operate constantly and fully loaded, on poor road conditions, and on uneven surfaces like bumps, depressions, and inclines. These impacts can easily lead to excessive deformation, cracks, and fractures, and even serious accidents such as rollovers. Furthermore, components have a limited design lifespan, and over time, fatigue and aging can affect their performance.

[0003] Therefore, to ensure vehicle safety, it's necessary to comprehensively consider factors such as load, road conditions, the environment, and the vehicle's condition before adopting an appropriate driving speed. However, existing technologies only consider the impact of road bumps, ignoring factors such as vehicle condition, environmental stress, and the remaining service life of components. This results in an inability to accurately control vehicle speed in a timely manner, and in no way reduces the probability of accidents, resulting in significant driving risks.

[0029] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the embodiments of the present application and are not used to limit the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] Figure 1 A schematic diagram of a flow chart of a vehicle control method according to an embodiment of the present application is shown. Figure 1 As shown, in one embodiment of the present application, a method for controlling a vehicle is provided, wherein the vehicle includes multiple components and comprises the following steps:

[0031] Step 101: Obtain the running speed of the vehicle.

[0032] Step 102 : Input the operating speed into a damage value calculation model to determine the damage value of each component at the operating speed.

[0033] Step 103 : determining the predicted remaining life of each component based on the damage value of each component and the length of time each component has been in use.

[0034] Step 104 : For any component, when the predicted remaining life of the component is less than a preset residual life value corresponding to the component, determine a target operating speed of the vehicle.

[0035] Step 105 : Input the target operating speed into the damage value calculation model to determine the damage value of each component at the target operating speed.

[0036] Step 106, again executing the step of determining the predicted remaining life of each component based on the damage value of each component and the length of time each component has been in use, until the predicted remaining life of each component is greater than the corresponding preset life residual value, and the corresponding target operating speed is determined as the speed limit of the vehicle.

[0037] Step 107: Control the vehicle to travel at a speed lower than the speed limit.

[0038] Parts are the components of the overall vehicle parts processing process, as well as products that serve the vehicle parts processing, such as frames, axles, wheels, and suspensions. The processor can obtain the vehicle's operating speed and input the operating speed into a damage value calculation model to determine the damage value of each component at that operating speed. After determining the damage value of each component, the processor can determine the predicted remaining life of each component based on the damage value and the length of time each component has been in service. After determining the predicted remaining life of each component, the processor can determine whether the predicted remaining life of any component is less than the corresponding remaining useful life value. If the predicted remaining life of the component is less than the corresponding preset residual life value, the processor can determine a target operating speed for the vehicle. After determining the target operating speed, the processor can input the target operating speed into the damage value calculation model to determine the damage value of each component at the target operating speed. The processor can repeatedly perform the step of determining the predicted remaining life of each component based on the damage value and the length of time each component has been in service until the predicted remaining life of each component is greater than the corresponding preset residual life value. The corresponding target operating speed is then determined as the vehicle's speed limit. After determining the speed limit of the vehicle, the processor may control the vehicle to travel at a speed lower than the speed limit.

[0039] The above technical solution can control the speed of the vehicle in real time so that the vehicle can travel safely, reduce the probability of vehicle failure, and improve the safety of vehicle operation.

[0040] In one embodiment, determining the predicted remaining life of each component based on the damage value of each component and the length of time each component has been in use includes: for any component, determining the ratio of the length of time the component has been in use to the damage value of the component; and determining the difference between the ratio of each component and the length of time each component has been in use as the predicted remaining life of each component.

[0041] The processor can determine the predicted remaining life of each component based on the damage value of each component and the length of time each component has been in use. Specifically, for any component, the processor can determine the ratio of the length of time each component has been in use to the damage value of the component. After determining the ratio, the processor can determine the difference between the ratio and the length of time each component has been in use as the predicted remaining life of each component.

[0042] For example, the processor can obtain the vehicle's operating speed and input it into the damage value calculation model to determine the damage value of each component at that operating speed. After determining the damage value, the processor can then determine the predicted remaining life of each component based on the damage value and the age of each component.

[0043] Specifically, for any component, the processor can determine the ratio of the component's service life to its damage value. After determining the ratio, the processor can determine the difference between the ratio and the service life of each component as the predicted remaining life of each component. Specifically, predicted remaining life = service life ÷ damage value - service life. After determining the predicted remaining life of each component, the processor can determine whether the predicted remaining life of each component is less than a preset residual life value corresponding to the component.

[0044] For any component, if the predicted remaining life of the component is less than the corresponding preset residual life value, the processor can determine the target operating speed of the vehicle. The target operating speed is then input into the damage value calculation model to determine the damage value of each component at the target operating speed. The processor can again perform the step of determining the predicted remaining life of each component based on the damage value and the length of time each component has been in use until the predicted remaining life of each component is greater than the corresponding preset residual life value. The processor can determine the corresponding target operating speed as the vehicle's speed limit and control the vehicle to travel at a speed below the speed limit to ensure that the vehicle can travel safely and that the components are in a sustainable state while the vehicle is driving, thereby reducing safety hazards.

[0045] In one embodiment, determining the target running speed of the vehicle includes: reducing a preset value based on the running speed of the vehicle to obtain the target running speed.

[0046] The processor can determine the target running speed of the vehicle. Specifically, the processor can reduce a preset value based on the running speed of the vehicle to obtain the target running speed.

[0047] For example, for any component, if the predicted remaining life of that component is less than the preset residual life value corresponding to that component, the processor can reduce the vehicle's operating speed V by 10 km / h to obtain a target operating speed V1. The processor can input the obtained target operating speed V1 into the damage value calculation model to obtain the damage value D1 of each component at the target operating speed V1. After obtaining the damage value D1, the processor can determine the predicted remaining life of each component based on the damage value D1 and the length of time each component has been in use.

[0048] When the predicted remaining life of any component is less than the preset residual life value corresponding to the component, the processor can reduce the vehicle's operating speed V1 by 10 km / h to obtain a target operating speed V2. The processor can input the obtained target operating speed V2 into the damage value calculation model to obtain the damage value D2 of each component at the target operating speed V2. After obtaining the damage value D2, the processor can determine the predicted remaining life of each component based on the damage value D2 of each component and the length of time each component has been in use. And the predicted remaining life of each component is greater than the corresponding preset residual life value. The processor can determine the target operating speed V2 as the speed limit of the vehicle. And control the vehicle to travel at a speed lower than the speed limit V2. By continuously iterating the vehicle's speed, the vehicle's speed limit is determined, and controlling the vehicle to run at a speed lower than the speed limit can timely constrain the vehicle speed and avoid triggering risks.

[0049] In one embodiment, controlling the vehicle to travel at a speed lower than the speed limit includes: generating a control signal corresponding to the speed limit; and controlling a power device of the vehicle according to the control signal so that the vehicle travels at a speed lower than the speed limit.

[0050] The processor may control the vehicle to travel at a speed lower than the speed limit. Specifically, the processor may generate a control signal corresponding to the speed limit. After generating the control signal, the processor may control the vehicle's power device according to the control signal to cause the vehicle to travel at a speed lower than the speed limit.

[0051] For example, the processor can generate a control signal corresponding to a speed limit. After generating the control signal, the processor can control the vehicle's fuel supply, throttle opening, and other parameters based on the control signal to ensure that the vehicle travels at a speed below the speed limit. This can eliminate the influence of external factors, ensure the safety of components, and improve vehicle driving safety.

[0052] In one embodiment, controlling the vehicle to travel at a speed lower than the speed limit includes: generating a warning signal corresponding to the speed limit; and sending the warning signal to a warning device of the vehicle to prompt a user to reduce the speed of the vehicle until the speed of the vehicle is lower than the speed limit.

[0053] The processor may control the vehicle to travel at a speed below the speed limit. Specifically, the processor may generate a warning signal corresponding to the speed limit. After generating the warning signal, the processor may transmit the warning signal to a warning device of the vehicle to prompt a user to reduce the vehicle's speed until the vehicle's speed is below the speed limit.

[0054] For example, the processor may generate a warning signal corresponding to the speed limit. After generating the warning signal, the processor may send the warning signal to the vehicle's cab speaker, speedometer, onboard vehicle system, etc., to prompt the user to reduce the vehicle's speed until the vehicle's speed is below the speed limit.

[0055] In one embodiment, the control method further includes: obtaining the vehicle's operating data and environmental data, wherein the operating data includes at least the vehicle's load data, operation data, and vehicle condition data, and the environmental data includes at least road condition data and temperature data; respectively determining the influence coefficients of the operating data and environmental data on the damage of each component; determining the initial damage value of each component based on the load data; and determining a damage value calculation model based on the initial damage values ​​of all components and all influence coefficients.

[0056] The processor can obtain the vehicle's operating condition data and environmental data. The operating condition data includes at least the vehicle's load data, operating data, and vehicle condition data. The environmental data includes at least road condition data and temperature data. After obtaining the operating condition data and environmental data, the processor can respectively determine the influence coefficients of the altitude data and environmental data on the damage of each component. The processor can determine the initial damage value of each component based on the load data. After determining the initial damage value of each component, the processor can determine a damage value calculation model based on the initial damage values ​​of all components and all influence coefficients.

[0057] For example, the processor can collect the vehicle's operating data and environmental data through sensors. The operating data includes at least the vehicle's load data, operation data, and vehicle condition data. The environmental data includes at least road condition data and temperature data. The processor can determine the influence coefficients of the operating data and environmental data on the damage of each component. For example, the road condition influence coefficient K4Φ4, the load influence coefficient K g M g , Temperature influence coefficient K T M T , operating speed influence coefficient K v M v .

[0058] The processor can determine the initial damage value of each component based on the load data. After determining the initial damage value, the processor can determine the damage value calculation model based on the initial damage values ​​of all components and all influence coefficients. The expression of the damage value calculation model is D o =D*(K4Φ4)*(K g M g )*(K T M T )*(K v M v ), where Do is the damage value, D is the initial damage value, K4 is the weight coefficient of the road condition data, K g is the weight coefficient of load data, K T is the weight coefficient of temperature data, K v is the weight coefficient of the running speed, Φ4 is the degradation coefficient of the road condition data, M g is the degradation coefficient of load data, K T is the degradation coefficient of temperature data, K4, K g , K T , K v 、Φ4、M g , K T are all constants, M v is the degradation coefficient of the operating speed.

[0059] In one embodiment, determining the initial damage value of each component based on the load data includes: obtaining the stress corresponding to the load data and the number of times the stress acts within a preset period; for any component, determining the number of times the component can withstand the stress within the preset period; for any component, determining the sum of the ratios of the number of times the stress acts within the preset period to the number of times the component is subjected to the stress as the initial damage value of the component.

[0060] The processor can determine the initial damage value of each component based on the load data. Specifically, the processor can obtain the stress corresponding to the load data and the number of times the stress is applied within a preset period. For any component, the processor can determine the number of times the component can withstand the stress within the preset period. For any component, the processor can determine the initial damage value of the component by summing the ratio of the number of times the stress is applied within the preset period to the number of times the component is subjected to the stress.

[0061] In one embodiment, the control method further includes: after controlling the vehicle to travel at a speed lower than the speed limit, storing the vehicle's operating condition data and the corresponding speed limit; obtaining new operating condition data of the vehicle, and comparing the new operating condition data with the stored operating condition data to determine target operating condition data corresponding to the new operating condition data; and controlling the vehicle under the new operating condition data to travel at a speed lower than the speed limit corresponding to the target operating condition data.

[0062] After controlling the vehicle to travel at a speed lower than the speed limit, the processor may store the vehicle's operating condition data and the corresponding speed limit. After storing the vehicle's operating condition data and the corresponding speed limit, the processor may obtain new operating condition data for the vehicle and compare the new operating condition data with the stored operating condition data to determine target operating condition data corresponding to the new operating condition data. After determining the target operating condition data, the processor may control the vehicle under the new operating condition data to travel at a speed lower than the speed limit corresponding to the target operating condition data. This can directly control the vehicle to travel at a speed lower than the corresponding speed limit, thereby improving the vehicle's response speed and reducing processing time.

[0063] In one embodiment, Figure 2 As shown, data can be transmitted between module 1: information acquisition module, module 2: reliability analysis, judgment and decision module, module 3: early warning module and module 4: database module.

[0064] In Module 1: Information Collection, the processor can collect the vehicle's average speed using speed sensors, load information using force sensors, road bumps using acceleration sensors, environmental stress information using temperature and humidity sensors, the usage time of each vehicle component using a usage recorder, and other sensors or instruments to collect other vehicle information. The processor can also obtain information such as component type and performance parameters. The processor can store this information in the database module or send it to the onboard reliability calculation system in Module 2.

[0065] In Module 2: Reliability Analysis, Judgment, and Decision-Making Module, the processor can calculate the predicted remaining life value f of each component of the vehicle through the vehicle reliability calculation system. Specifically, the processor can determine the influence coefficient of average vehicle speed information, load information, road bump information, and environmental stress information on the damage of each component of the vehicle. The processor can also determine the initial damage value of each component based on the load information. For example, the processor can determine the stress corresponding to the load information and the number of times the stress acts within a preset period n. i The processor can determine the number of times N that each component can withstand stress within a preset cycle. i The processor can set the number of actions n within the preset cycle i The number of times N that the component is subjected to i The sum of the ratios is determined as the initial damage value of the component.

[0066] The average speed information of the vehicle is input into the damage value calculation model in the vehicle reliability calculation system to determine the damage value of each component at the operating speed. The expression of the damage value calculation model is D o= D * (K4Φ4) * (K g M g ) * (K T M T ) * (K v M v ), where D o is the damage value, D is the initial damage value, K4 is the weight coefficient of road condition data, K g is the weight coefficient of load data, K T is the weight coefficient of temperature data, K v is the weight coefficient of running speed, Φ4 is the deterioration coefficient of road condition data, M g is the deterioration coefficient of load data, K T is the deterioration coefficient of temperature data, K4, K g , K T , K v , Φ4, M g , K T are all constants, M v is the deterioration coefficient of running speed.

[0067] After obtaining the damage value, the processor can determine the predicted remaining life value f of each component based on the damage value of each component and the used duration of each component, that is, the predicted remaining life f = used duration ÷ damage value - used duration. For any component, the processor can compare the predicted remaining life value f of the component with the designed remaining life f0. When f ≥ f0, the processor can control the vehicle to drive normally.

[0068] When f < f0, the processor can perform iterative calculation of the speed limit value. For example, for any component, when f < f0 for the component, the processor can reduce the running speed V of the vehicle by 10 km / h to obtain the target running speed V1. The processor can input the obtained target running speed V1 into the damage value calculation model to obtain the damage value D1 of each component at the target running speed V1. After obtaining the damage value D1, the processor can determine the predicted remaining life value f of each component based on the damage value D1 of each component and the used duration of each component.

[0069] When f < f0 for any component, the processor can reduce the vehicle's operating speed V1 by 10 km / h to obtain the target operating speed V2. The processor can input the obtained target operating speed V2 into the damage value calculation model to obtain the damage value D2 of each component at the target operating speed V2. After obtaining the damage value D2, the processor can determine the predicted remaining life f of each component based on the damage value D2 of each component and the used duration of each component. And f ≥ f0 for each component. The processor can determine the target operating speed V2 as the maximum speed limit of the vehicle.

[0070] The processor can output the maximum speed limit V2. The processor can also generate a vehicle speed warning signal corresponding to the maximum speed limit V2 and output the vehicle speed warning signal. Among them, on the one hand, the vehicle speed warning signal can limit the driving power output. For example, it can limit the fuel supply amount, throttle opening, etc. to reduce the vehicle speed below the maximum speed limit V2. On the other hand, the vehicle speed warning signal can remind the driver to release the accelerator and step on the brake to reduce the vehicle speed below the maximum speed limit V2.

[0071] The processor can compare the new information collected by the sensor with the information in the database module to determine the target information corresponding to the new information in the database module and control the vehicle to drive at a speed lower than the maximum speed limit corresponding to the target information.

[0072] The above technical solution obtains the operating speed of the vehicle; inputs the operating speed into the damage value calculation model to determine the damage value of each component at the operating speed; determines the predicted remaining life of each component according to the damage value of each component and the used duration of each component; for any component, when the predicted remaining life of the component is less than the preset life residual value corresponding to the component, determines the target operating speed of the vehicle; inputs the target operating speed into the damage value calculation model to determine the damage value of each component at the target operating speed; and repeats the step of determining the predicted remaining life of each component according to the damage value of each component and the used duration of each component until the predicted remaining life of each component is greater than the corresponding preset life residual value, and determines the corresponding target operating speed as the speed limit of the vehicle; controls the vehicle to drive at a speed lower than the speed limit. Adopting the above technical solution can control the vehicle speed in real time, enable the vehicle to drive safely, reduce the probability of vehicle failures, and improve the safety of vehicle operation.
