[0028] In actual implementation, the target vehicle can be a vehicle using corner module technology or any other theoretically feasible vehicle; this application does not impose any specific restrictions on this.

[0029] In actual implementation, the suspension system can be the entire suspension system of the target vehicle, or it can be a partial suspension system of the target vehicle, such as the corner module suspension structure corresponding to one of the four wheels of the target vehicle.

[0030] In actual implementation, the suspension system may include several suspension components, including but not limited to the upper control arm, steering motor, tires, steering knuckle, lower control arm, etc.

[0034] Step 120: Simulate the target working condition using the angular module dynamic model, and obtain the decomposed load of each suspension component through simulation calculation; the number of target working conditions is at least one.

[0035] In actual execution, the target working condition may include at least one of the following: acceleration working condition, braking working condition, impact working condition, pit landing working condition, first lateral force working condition, and second lateral force working condition.

[0036] In some embodiments, a target working condition can be input into the corner module dynamics model for simulation, and the decomposed load of each suspension component in the suspension system under the target working condition can be obtained through simulation calculation.

[0037] In some embodiments, durability analysis can be performed on the target vehicle based on the decomposed load of each suspension component in the suspension system under different target operating conditions, so as to improve the structural design and performance of the target vehicle.

[0038] According to the vehicle component load decomposition method of this application embodiment, a corner module dynamic model of the suspension system of the target vehicle is constructed. The suspension system includes several suspension components, and the corner module dynamic model includes sub-models corresponding to each suspension component in the suspension system and the kinematic connection relationships between each sub-model. The target working condition is simulated and input into the corner module dynamic model, and the decomposed load of each suspension component is obtained through simulation calculation. By constructing a corner module dynamic model including sub-models of each suspension component and the kinematic connection relationships between each sub-model, the decomposed load of each suspension component can be simulated and obtained, thereby solving the problem that it is difficult to analyze the load conditions of each suspension component in the corner module under different working conditions.

[0047] In some embodiments, a sub-model of the suspension component is constructed based on the component parameter information of each suspension component; and a connection relationship between the sub-models corresponding to two adjacent suspension components is established based on the constraint information between each two adjacent suspension components to generate a corner module dynamic model.

[0048] In some embodiments, for each suspension component, a sub-model of the suspension component can be constructed based on information such as its three-dimensional structure and model number. For example, a sub-model of the suspension component can be constructed by scaling down the model proportionally based on its three-dimensional structure, model number, and other information.

[0049] In actual implementation, the constraint information between two suspension components can represent the relative kinematic connection relationship between two adjacent suspension components. For example, suspension component A can be rotated 180 degrees with the connection point 1 between suspension component A and suspension component B as the center of rotation.

[0050] In some practical implementations, for all suspension components in the target vehicle's suspension system, the connection relationship between the sub-models corresponding to two adjacent suspension components can be established based on the constraint information between each pair of adjacent suspension components, until all suspension components in the suspension system are traversed, so as to "assemble" the sub-models corresponding to all suspension components in the suspension system into a corner module dynamic model.

For example, each suspension component can be verified to check whether it conforms to the constraint information.

[0054] In some embodiments, if the verification results indicate that the corner module dynamics model is accurate, there is no need to update the corner module dynamics model.

[0055] In some embodiments, if the verification results indicate that the corner module dynamics model is inaccurate, the corner module dynamics model is updated. For example, the inaccurate sub-models in the corner module dynamics model are updated.

[0072] In actual implementation, the target vehicle can be a vehicle using corner module technology or any other theoretically feasible vehicle; this application does not impose any specific restrictions on this.

[0073] In actual implementation, the suspension system can be the entire suspension system of the target vehicle, or it can be a partial suspension system of the target vehicle, such as the corner module suspension structure corresponding to one of the four wheels of the target vehicle.

[0074] In actual implementation, the suspension system may include several suspension components, including but not limited to the upper control arm, steering motor, tire, steering knuckle, lower control arm, spring-loaded suspension assembly, and stabilizer bar assembly.

[0075] In actual implementation, the component parameter information for each suspension component can include the name, three-dimensional structure, model, and other information of that suspension component.

[0076] In actual implementation, the constraint information between two adjacent suspension components can represent the relative motion relationship between the two adjacent suspension components, such as the degree of freedom between the two adjacent suspension components.
