[0021] Example 1 In an embodiment of the present invention, a suspension dynamic adjustment method based on a UE5 Chaos vehicle plug-in is provided, comprising: constructing a vehicle and its dynamic model based on the UE5 Chaos vehicle plug-in; obtaining the suspension of the vehicle from the dynamic model, and changing the center of gravity position of the vehicle by adjusting the stroke and stiffness of the suspension; in the dynamic model, modifying relevant parameters of the engine and the gearbox, and adjusting the dynamic output of the engine and the gearbox.

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Figure 1 This is a flow chart of a suspension dynamic adjustment method based on a UE5 Chaos vehicle plug-in according to an embodiment of the present invention. Figure 1 , the specific implementation methods of the present invention are described in detail.

[0024] In step 101, a vehicle and its dynamics model are constructed based on the UE5 Chaos vehicle plug-in.

[0025] In an embodiment of the present invention, a vehicle is constructed based on the Chaos vehicle plug-in of UE5 (the latest generation of Unreal Engine). First, a 3D vehicle model with suitable proportions and details of the vehicle needs to be prepared. In order to make the vehicle have a realistic appearance in the game, it is necessary to create appropriate materials and textures for the model. This can include body color, mapping, and detail textures. In order to achieve physical simulation and collision detection, it is necessary to create appropriate collision bodies for the vehicle. In order to make the vehicle have a realistic movement posture, it is necessary to create corresponding skeletons and bones on the 3D vehicle model. Finally, a vehicle blueprint is created to control and manage the logical behavior of the vehicle.

[0026] Vehicle blueprints in Unreal Engine (UE) refer to blueprint scripts used to create and control in-game vehicles (such as cars, trucks, motorcycles, etc.). Blueprints are a visual programming tool that allows developers to build game logic through nodes and connecting lines without writing traditional code. In Unreal Engine, vehicle blueprints usually involve the following aspects: The basic structure of the vehicle: including the body, wheels, suspension system, etc. These elements are usually represented by static meshes and need to be correctly combined to form the appearance of the vehicle.

[0027] Physics and Dynamics: In order for a vehicle to move and interact realistically in the game, physical properties and dynamics parameters need to be set. This includes mass, friction, engine power, brake system, etc.

[0028] Control logic: defines how the player controls the vehicle. For example, the vehicle's acceleration, braking, steering, and gear shifting can be controlled through keyboard, mouse, or game controller input.

[0029] Animation and special effects: Add animation and visual effects to vehicles, such as spinning wheels, flashing brake lights, smoke effects from the exhaust pipe, etc.

[0030] AI and traffic systems: If there are self-driving vehicles or traffic systems in the game, you will also need to write the corresponding AI logic so that the vehicles can automatically navigate, avoid obstacles, obey traffic rules, etc.

[0031] By using vehicle blueprints, developers can quickly create and test various types of vehicles, and can perform complex customization and optimization as needed. This is very important for many modern games, because realistic vehicle simulation can greatly enhance the realism and immersion of the game.

[0032] In an embodiment of the present invention, a vehicle and its dynamic model are constructed based on the UE5 Chaos vehicle plug-in. The dynamic model includes all simulation parameters of the vehicle's suspension in the Chaos physics engine, as well as relevant parameters of the vehicle's engine and gearbox.

[0033] In step 102 , the travel and stiffness of the suspension are dynamically adjusted to change the center of gravity position of the vehicle.

[0034] Figure 2 , Figure 3 The key code for setting suspension parameters is shown. The Suspension object of the vehicle physics instance PVehicle (the vehicle's dynamic model) contains all the simulation parameters of the vehicle suspension in the Chaos physics engine. PVehicle is a specific instance of VehicleSimulationPT, which is a physical type in the Chaos vehicle system in UE, used to simulate the physical behavior of the vehicle. Get the vehicle Suspension from PVehicle, modify the SuspensionMaxRaise (maximum suspension lift), SuspensionMaxDrop (maximum suspension drop), DampingRatio (damping coefficient), SpringPreload (spring preload), SpringRate (spring coefficient) and other parameters, and you can dynamically adjust the suspension's travel, stiffness and other important physical parameters. By adjusting the suspension travel and stiffness, you can change the center of gravity of the vehicle, which can also affect the vehicle's handling, stability, and passability.

[0035] Damping Ratio: refers to the characteristic of any vibration system that the vibration amplitude gradually decreases during vibration due to external factors or inherent reasons of the system itself, and the characterization of this characteristic. Damping controls the shock absorption effect of the suspension system. The appropriate damping setting can reduce vibration when the vehicle encounters bumpy roads and provide a smoother driving experience.

[0036] Preload is one of the commonly used suspension system parameters and configurations, which refers to the pressure applied to the suspension system when the vehicle is stationary. Increasing preload can improve the firmness of the suspension system and make it easier for the vehicle to maintain good ground contact. SpringPreload refers to the pressure applied to the spring when it is stationary. This means that the spring should be properly compressed when the vehicle is stationary to ensure that it can provide the best support and shock absorption effect during the vehicle's driving. The purpose of preload is to make the spring in a certain degree of compression when the vehicle is stationary, so that during driving, the spring can respond to changes in the road surface more quickly and provide more stable support. Appropriate preload can reduce the shaking of the vehicle during driving, improve the accuracy of control and ride comfort.

[0037] SpringRate (spring coefficient) refers to the ratio between the elastic force generated by the spring after a unit force is applied to its deformation. It is the same concept as spring stiffness. Spring stiffness determines the hardness of the suspension system. A higher spring stiffness will make the suspension system stronger and the vehicle more stable during driving, but it will also cause the vehicle's suspension travel to become smaller. Generally, if the spring stiffness is larger, the vehicle will be more stable during driving, but the vehicle's suspension comfort may be reduced; if the spring stiffness is smaller, the vehicle's suspension comfort will be improved, but the stability may be reduced. In other words, spring stiffness is an indicator of the spring's resistance to external forces, and it plays an important role in the performance and design of the suspension system. By choosing the right spring stiffness, you can achieve ideal suspension comfort, stability and handling performance.

[0038] In addition, commonly used suspension system parameters and configurations include suspension travel, which refers to the distance the suspension system can move vertically. A larger suspension travel can provide better wheel flexibility and adapt to changes in different road surfaces. In this embodiment, the suspension travel is represented by SuspensionMaxRaise and SuspensionMaxDrop. By adjusting these parameters, developers can create different types of suspension systems as needed, from soft suspension systems (suitable for off-road vehicles) to stiff suspension systems (suitable for racing cars) to achieve the desired driving experience.

[0039] In step 103, relevant parameters of the engine and the gearbox are modified to adjust the power output of the engine and the gearbox.

[0040] The engine parameters of Chaos vehicles require the use of the vehicle's dynamics model PVehicle, which contains engine-related parameters such as horsepower, torque MaxTorque, and maximum speed MaxRPM. The Chasos physics engine will calculate the corresponding forces and torques based on the engine parameters and inputs (such as throttle and brake) to simulate the acceleration, braking, and steering behaviors of the vehicle. By adjusting these parameters, you can affect the behavior and performance of the engine in the game. The PVehicle model contains parameters related to the gearbox, such as the gear ratio ForwardGearRatios, the shift speed ChangeUpRPM (increase the speed), ChangeDownRPM (reduce the speed), etc. By adjusting these parameters, you can affect the gearbox's shifting logic and performance in the game. By changing the relevant parameters of the engine and gearbox, you can get the appropriate power output of the vehicle under this suspension state.

[0041] The suspension dynamic adjustment method based on the UE5 Chaos vehicle plug-in provided by the present invention can dynamically adjust the suspension stroke and hardness and adjust the height of the vehicle body posture. Dynamically adjust the parameters of the engine and gearbox to achieve corresponding power output at different vehicle body postures. By adjusting the suspension stroke, the ground clearance of the vehicle can be changed, which can be used to adapt to different terrains. The suspension stiffness determines the shock absorption effect of the vehicle when passing through different types of obstacles. Adjusting the suspension stiffness can improve the stability and controllability of the vehicle. The method proposed by the present invention can realize the switching of vehicle driving modes in the game, so that the same vehicle can have different suspension characteristics, suitable for driving needs of different terrains, and give players a richer driving experience.

Figure 4 As shown, the electronic device of the present invention includes a processor 401 and a memory 402, wherein: The memory 402 stores a computer program. When the computer program is read and executed by the processor 401, the computer program executes the steps in the embodiment of the suspension dynamic adjustment method based on the UE5 Chaos vehicle plug-in as described above.
