The invention discloses a mixed reality automatic driving test method and a virtual test platform oriented towards an intelligent network connection demonstration area. The test method includes a virtual test, and the virtual test includes: S1, creating a virtual vehicle driving environment, establishing a vehicle dynamics model and an on-board vehicle Sensing system model; S2, make the vehicle dynamics model run in unmanned mode to test its performance; S3, make the obstacle vehicle change, test the corresponding automatic manipulation behavior of the vehicle dynamics model; S4, make the vehicle dynamics model press The manual driving mode is operated to test the manual takeover operation performance of the vehicle dynamics model; S5, the test data is recorded and the test data is analyzed. The test method can realize real-time man-machine switching driving mode, which improves the driving safety of the vehicle; and can realize the automatic driving trajectory planning, trajectory tracking and the test of the actuator control performance in the virtual intelligent network demonstration area scenario. Reduce test costs and improve test efficiency.
Description
technical field [0001] The invention relates to the technical field of unmanned driving, in particular to a mixed reality automatic driving test method and a virtual test platform for an intelligent networked demonstration area. Background technique [0002] With the rapid development of autonomous vehicles, our travel will become more efficient and more environmentally friendly. It can not only make up for the lack of human sensory ability, eliminate traffic accidents caused by human factors, reduce the intensity of human driving operations, but also control and predict The behavior and running status of the car, and a reasonable travel path is planned according to the real-time road condition information. But in recent years, Tesla, Google, Uber and other companies have sparked panic about self-driving vehicles due to a series of traffic accidents caused by unstable and insufficient testing of their self-driving vehicle systems. Therefore, in order to ensure the safety an...
