[0045] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiment
[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0047] Refer to Figure 1 , Figure 1 is a schematic structural diagram of a vehicle counterweight control device in the hardware operating environment involved in the embodiment solution of the present invention.
[0048] As Figure 1 shown, the vehicle counterweight control device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and optionally the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless-fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM), or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may optionally also be a storage device independent of the aforementioned processor 1001.
[0049] Those skilled in the art can understand that Figure 1 the structure shown in Figure 1 does not constitute a limitation on the vehicle counterweight control device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0050] As Figure 1 shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a vehicle counterweight control program.
[0051] In Figure 1 the vehicle counterweight control device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the vehicle counterweight control device of the present invention may be arranged in the vehicle counterweight control device. The vehicle counterweight control device calls the vehicle counterweight control program stored in the memory 1005 through the processor 1001 and executes the vehicle counterweight control method provided by the embodiments of the present invention.
[0052] The embodiments of the present invention provide a vehicle counterweight control method. Referring to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of a vehicle counterweight control method of the present invention.
[0053] In this embodiment, the vehicle counterweight control method includes the following steps:
[0054] Step S10: When it is detected that the target vehicle is in a driving state, obtain the center of gravity position and the axle load parameters of the target vehicle.
[0055] It should be noted that the execution subject of the method in this embodiment may be a vehicle counterweight control device, where the vehicle counterweight control device may be a device with data processing and data transmission capabilities, such as: a computer, a vehicle-mounted controller, and a mobile phone, etc. This embodiment does not make specific limitations in this regard. In this embodiment and the following embodiments, the vehicle-mounted controller will be used as an example for illustration.
[0056] It is worth noting that the center of gravity position refers to the midpoint position of the vehicle's gravity. Since in theoretical calculations, parameters such as the vehicle's speed, acceleration, and centrifugal force need to consider the vehicle as a point for convenient data calculation. In actual operation, the center of gravity position of the vehicle can be used as the midpoint for data calculation. Among them, the center of gravity position of the vehicle is related to parameters such as the vehicle's drive mode, load, and wheelbase. Since it is relatively difficult to change information such as the vehicle's drive mode and wheelbase during driving, the theoretical center of gravity position of the vehicle can be changed by adjusting the load at the front and rear ends of the vehicle.
[0057] In specific implementation, the position of the center of gravity of the vehicle affects the power performance, braking performance, and handling stability of the vehicle. Among them, if the vehicle is a front-wheel drive vehicle and the center of gravity of the vehicle is forward, the power performance is stronger. When the center of gravity is forward, the axle load of the front wheels is greater. When braking is required, the front wheels will lock up before the rear wheels, and the braking performance is stronger. At the same time, if the center of gravity is relatively high, the handling stability of the vehicle during turning will be lower, which is not conducive to safe driving.
[0058] It should be noted immediately that the axle load parameter refers to the axle weight of the vehicle, that is, the weight that the axle can bear. Due to different vehicle loads, the front and rear axle weights of the vehicle will be different. The end with a larger axle weight will cause more serious wear on the tires and bearings at the corresponding end of the vehicle, which is not conducive to the safety of users. To avoid affecting the safety of users, the distribution of the front and rear axle loads of the vehicle can be 1:1, and this embodiment does not make specific restrictions on this.
[0059] In specific implementation, during the driving process of the vehicle, due to the acceleration or deceleration of the vehicle, a driving additional force will be generated on the vehicle. This driving additional force will cause the theoretical center of gravity of the vehicle to shift, thereby changing the braking performance, power performance, and handling stability during the driving process of the vehicle, and will affect the safety performance of the vehicle.
[0060] Step S20: Determine the deviation of the center of gravity to be adjusted according to the position of the center of gravity and the standard center of gravity position, and determine the axle load difference based on the axle load parameter and the standard axle load parameter.
[0061] It should be understood that the standard center of gravity position refers to the center of gravity position of the target vehicle in the theoretical state during the driving process; the standard axle load parameter refers to the center of gravity position of the target vehicle in the theoretical state during the driving process. Among them, the standard center of gravity position is related to the vehicle model and the driving mode of the vehicle, and when the target vehicle is in the state of the standard center of gravity position and the standard axle load parameter, the braking performance, handling performance, and power performance of the vehicle driving are less affected, improving the safety of vehicle driving.
[0062] Further, in order to obtain the standard center of gravity position and the standard axle load parameter of the target vehicle, the step S20 includes:
[0063] Obtain the vehicle model and driving mode of the target vehicle;
[0064] Match the data through a preset vehicle database according to the vehicle model and the driving mode to obtain the standard center of gravity position and the standard axle load parameter of the target vehicle.
[0065] It can be understood that the vehicle model includes: seat configuration and equipment configuration of the target vehicle, etc., and the driving mode includes: front-wheel drive, rear-wheel drive, and four-wheel drive, etc. This embodiment does not make specific restrictions on this.
[0066] It is easy to understand that a preset vehicle database is used to store the models, driving modes, and corresponding standard vehicle parameters of various vehicles. The standard center-of-gravity position and standard axle load parameters of the corresponding vehicle during driving can be queried from the preset database according to the vehicle model and vehicle driving mode.
[0067] It should be understood that the center-of-gravity deviation to be adjusted refers to the deviation between the actual center-of-gravity position and the standard center-of-gravity position of the vehicle during driving, and the axle load difference refers to the difference between the front and rear axle loads of the vehicle and the standard axle load. Among them, the center-of-gravity deviation to be adjusted not only refers to the deviation between the front and rear ends of the vehicle, but also includes: the height deviation of the center-of-gravity position of the vehicle, etc. This embodiment does not make specific restrictions on this.
[0068] Step S30: Update the weight distribution information of the target vehicle based on the center-of-gravity deviation to be adjusted and the axle load difference.
[0069] It should be noted that in this embodiment, by equipping a magnetic induction device at the chassis of the target vehicle, the magnetic induction device is controlled according to the center-of-gravity deviation to be adjusted and the axle load difference to adjust the weight distribution at the front and rear ends of the vehicle, so as to update the weight distribution information of the target vehicle.
[0070] Further, the step S30 includes:
[0071] Based on the center-of-gravity deviation to be adjusted and the axle load difference, perform a weight ratio calculation through a preset weight ratio model to obtain weight ratio information;
[0072] Control the weight adjustment device according to the weight ratio information, so that the weight adjustment device updates the weight distribution information of the target vehicle.
[0073] It can be understood that the preset weight ratio model is used to obtain the weights that need to be adjusted at the front and rear ends of the vehicle according to the center-of-gravity deviation to be adjusted and the axle load difference. In the actual operation process, in order to ensure the braking performance and controllability of the vehicle, the axle load distribution ratio at the front and rear ends of the vehicle can be made close to 1:1, and according to the different driving modes of the vehicle, the load at the front and rear ends of the vehicle can be adjusted so that the axle load distribution ratio at the front and rear ends of the vehicle is close to 1:1.
[0074] In a specific implementation, the weight adjustment device can be a magnetic induction device installed on the vehicle chassis to adjust the weight at the front and rear ends of the vehicle through magnetic induction, or it can be other weight adjustment devices with the same or similar functions. This embodiment does not make specific restrictions on this.
[0075] When it is detected that the target vehicle is in a driving state, obtain the center-of-gravity position and axle load parameters of the target vehicle; determine the center-of-gravity deviation to be adjusted according to the center-of-gravity position and the standard center-of-gravity position, and determine the axle load difference based on the axle load parameters and the standard axle load parameters; update the weight distribution information of the target vehicle based on the center-of-gravity deviation to be adjusted and the axle load difference. In this embodiment, by obtaining the center-of-gravity position and axle load parameters during the driving process of the vehicle, the deviation between the actual center-of-gravity position and actual axle load parameters of the vehicle during driving and the standard parameters is determined, so as to adjust the weight distribution at the front and rear ends of the vehicle according to the deviation, thereby controlling the loads at the front and rear ends of the vehicle, and avoiding the technical problem of potential safety hazards existing in the prior art that the center-of-gravity position and the front and rear axle loads of the vehicle are affected due to different loads at the front and rear ends during the driving process of the vehicle.
[0076] Reference Figure 3 , Figure 3 is a schematic flow chart of the second embodiment of a vehicle weight distribution control method of the present invention.
[0077] Based on the above first embodiment, in this embodiment, the step S10 includes:
[0078] Step S101: Obtain the vehicle component parameters, vehicle load parameters, and axle braking force of the target vehicle.
[0079] It should be noted that the vehicle component parameters refer to the mass information, center-of-gravity position information, and component positions of each vehicle component. The vehicle load parameters include: the load information when the vehicle is unloaded and the current load information of the vehicle. The axle braking force refers to the braking force of the vehicle in an emergency braking situation.
[0080] Step S102: Determine the center-of-gravity position of the target vehicle according to the vehicle component parameters and the vehicle load parameters.
[0081] It can be understood that according to the vehicle component parameters, the center-of-gravity positions of each vehicle component can be determined, and based on the center-of-gravity positions of each vehicle component and the vehicle load, the center-of-gravity position of the entire vehicle can be determined.
[0082] Further, the step S102 includes:
[0083] Obtain the wheelbase information and curb weight of the target vehicle;
[0084] Extract the vehicle static load from the vehicle load parameters;
[0085] Determine the unloaded center-of-gravity position of the vehicle according to the vehicle static load, wheelbase information, and the curb weight of the vehicle;
[0086] Determine the center-of-gravity position of the target vehicle according to the unloaded center-of-gravity position of the vehicle and the vehicle component parameters.
[0087] It should be noted that the wheelbase information is the distance between the midpoints of two adjacent wheels on the same side of the vehicle and perpendicular to the two perpendicular lines of the vehicle's longitudinal symmetry plane. The curb weight of the vehicle refers to the self-weight of the vehicle when it leaves the factory. Since different components will be installed according to the needs of users when purchasing a vehicle, for example: there are optional seat configurations for 7-seater vehicles: 5-seater, 6-seater and 7-seater. Different seats result in different vehicle loads, but the curb weight of the vehicle is the same.
[0088] In addition, the vehicle static load refers to the load information corresponding to the front and rear axles of the vehicle under the curb weight.
[0089] The formula for obtaining the position of the vehicle's unloaded center of gravity is:
[0090] h = ∑miyi / G
[0091] Where h is the height of the vehicle's center of gravity, mi is the mass of the vehicle component, yi is the height of the component's center of gravity, and G is the total mass of the vehicle.
[0092] L1 = G1L / G
[0093] L2 = G2L / G
[0094] Where L1 is the longitudinal position of the vehicle's center of gravity, L2 is the lateral position of the vehicle's center of gravity, G2 is the static front axle load, G1 is the static rear axle load, and L is the vehicle wheelbase + 650mm.
[0095] In addition, the formula for obtaining the front and rear static axle loads is:
[0096] G2 = ∑mixi / L
[0097] Where mi is the weight of the component and xi is the horizontal position of the component's center of gravity.
[0098] Step S103: Determine the axle load parameters of the target vehicle according to the axle braking force and the vehicle load parameters.
[0099] Furthermore, in order to ensure that the partial ratio of the front and rear axle loads is within an appropriate range, step S103 includes:
[0100] Obtain the static axle load of the axle;
[0101] Extract the front axle braking force and the rear axle braking force from the axle braking force, and extract the front axle static load and the rear axle static load from the axle static load;
[0102] Determine the front axle dynamic load according to the front axle braking force, the front axle static load and the vehicle load parameters;
[0103] Determine the rear axle dynamic load according to the rear axle braking force, the rear axle static load, and the vehicle load parameter.
[0104] Generate the axle load parameter of the target vehicle based on the front axle dynamic load and the rear axle dynamic load.
[0105] In a specific implementation, assume that the curb weight G of a vehicle is 80040N, the static loads are: 24160N for the front axle and 55880N for the rear axle, the front axle braking force during emergency braking is 29010N, the rear axle braking force is 28540N, and the total braking force is 57550N. Then the front axle dynamic load is the front axle braking force / the front axle static load, which is 29010 / 24160 = 120%; the rear axle dynamic load is the rear axle braking force / the rear axle static load, which is FeR / GR = 28540 / 55880 = 51%; and the total braking force / the curb weight is 71.9%.
[0106] This embodiment discloses obtaining the vehicle component parameter, the vehicle load parameter, and the axle braking force of the target vehicle; determining the center of gravity position of the target vehicle according to the vehicle component parameter and the vehicle load parameter; and determining the axle load parameter of the target vehicle according to the axle braking force and the vehicle load parameter. This embodiment determines the axle load parameter and the center of gravity position of the target vehicle through the vehicle's component parameter, load parameter, and axle braking force, so as to realize the comparison between the center of gravity position and the standard center of gravity position and between the axle load parameter and the standard axle load parameter, and improve the accuracy of controlling the vehicle weight distribution.
[0107] Reference Figure 4 , Figure 4 is a schematic flowchart of the third embodiment of a vehicle weight distribution control method of the present invention.
[0108] Based on the above first embodiment, in this embodiment, after the step S30, the following is further included:
[0109] Step S40: When receiving a braking signal, obtain the current vehicle speed and the driving mode of the target vehicle.
[0110] It should be noted that the braking signal refers to a control signal input by the user when they need to reduce the vehicle speed, such as braking or coasting, etc. The current vehicle speed refers to the vehicle speed when obtaining the center of gravity position and the axle load parameter during the driving state of the vehicle; the driving mode includes: front-wheel drive, rear-wheel drive, and four-wheel drive, and this embodiment does not make specific limitations on this.
[0111] Step S50: Determine the braking weight to be adjusted according to the current vehicle speed and the driving mode, and control the weight adjustment device based on the braking weight to be adjusted, so that the weight adjustment device updates the weight information of the target vehicle.
[0112] It should be noted that the braking counterweight to be adjusted refers to the counterweight for increasing the braking speed according to the vehicle drive mode. For example, when the vehicle is a front-wheel drive vehicle and the load ratio between the front end and the rear end of the vehicle is 51:49, if the current vehicle speed is 60 km / h, the braking counterweight to be adjusted can be controlled so that the load ratio between the front end and the rear end of the vehicle is 40:60 to increase the braking efficiency.
[0113] In addition, an embodiment of the present invention further provides a storage medium, on which a vehicle counterweight control program is stored. When the vehicle counterweight control program is executed by a processor, the steps of the vehicle counterweight control method described above are implemented.
[0114] Since this storage medium adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one.
[0115] Refer to Figure 5 , Figure 5 which is a structural block diagram of the first embodiment of the vehicle counterweight control device of the present invention.
