Design error simulation based on error modeling and sampling techniques

Research on hardware in the loop simulation error based on driver assistance function testing

“…The influencing factors of the test error in the simulation test are mainly reflected in the following three aspects: Vehicle dynamics simulation model: Although vehicle dynamics simulation is a relatively basic link, it is an indispensable and important basis for the construction of autonomous driving simulation test system. The vehicle model, which is built based on the dynamics, Multiple real components, including vehicle body, steering mechanism, suspension, tires, brake, To realize the posture and dynamics simulation the vehicle model movement, In the process of model building, The completeness and precision of the parameter setting can directly affect the dynamics performance of the vehicle, Such as the absence of necessary parameters in the vehicle steering system, The model will show slow or excessive in the steering process, Even if the ADAS function can output the correct control instructions, Feedback to the vehicle performance is far from the real vehicle, Seriously affect the judgment of functional reliability [5].…”
