First embodiment
The applicant researches and discovers that in real life, when vehicle accidents such as tire burst, brake failure, direction failure and the like occur in the driving process of an automobile or other vehicles, the driving performance of the vehicle is influenced slightly, and when the vehicle accidents occur, the vehicle is damaged and people are killed, and in a sand table-based vehicle simulation driving system, a driver does not need to drive in a real vehicle, so that safety accidents can be avoided, and the driving training cost is reduced. However, most of the existing vehicle driving simulation systems perform full-virtualization simulation on driving situations through pure software, wherein the simulation on vehicle damage conditions is also performed through software calculation, and since simulation results obtained through a virtual simulation algorithm cannot be completely consistent with actual conditions, the existing method for virtually simulating vehicle driving and damage conditions has the problem that the reduction degree of real vehicle driving conditions and damage conditions is insufficient. In order to solve the above problems, a vehicle damage simulation method according to a first embodiment of the present invention is provided, referring to fig. 1, and fig. 1 is a flowchart of a vehicle damage simulation method according to a first embodiment of the present invention.

Step S23: and judging whether the first pressure value is larger than a first threshold value.
Step S24: and when the first pressure value is larger than a first threshold value, adjusting the state of the first vehicle part corresponding to the installation position of the first sensor in the damage state data to be a damaged state.
For step S21, the sensing information may be position, speed, acceleration, angular velocity, etc. of the vehicle collected by an attitude sensor, a ranging sensor, a GPS positioning module and/or a pressure sensor mounted on the vehicle. Meanwhile, the pre-established three-dimensional models of the vehicles and the simulated racing yards also comprise physical attribute parameters of the vehicles and all parts of the simulated racing yards, and the physical attribute parameters generally comprise the attributes influencing collision results, such as hardness, rigidity, weight, friction force and the like, so that the collision parameters are obtained in simulation software through mathematical modeling. The collision parameters comprise pressure values born by each part of the vehicle in collision.
For step S23: and judging whether the first pressure value is larger than a first threshold value. The first threshold value may be specifically adjusted according to the type, importance degree, and the like of the first vehicle component corresponding to the first sensor mounting position.
After step S20 is executed, step S30 should be executed in order: and controlling the vehicle based on the damage state data and simulating a corresponding damage state and driving feeling on a physical layer by using a simulated driving cabin for controlling the vehicle. As an embodiment, the step of implementing step S30 may include: determining whether the first vehicle component is in a damaged state based on the damage state data; if so, controlling the whole vehicle control system of the vehicle to change the opening and closing state and/or the controlled degree of the first vehicle part based on the damage state data, simulating a corresponding damage state on a physical layer, adjusting parameters of each operating device in a simulated cockpit for controlling the vehicle based on the damage state data, and simulating a corresponding driving feeling on the physical layer.
