Description

Technical Field

[0001] The utility model relates to the technical field of driving simulators, in particular to a multi-freedom driving simulator for driving tests. Background Art

[0002] Multi-degree-of-freedom driving simulation is a technology that simulates the driving experience. It allows drivers to feel the real driving sensation in a virtual environment, including vehicle movement, vibration, sound, etc. Multi-degree-of-freedom driving simulation technology is widely used in automotive research and development, driving training, game entertainment and other fields. It can provide a highly realistic driving experience and help drivers better understand vehicle performance and driving skills.

[0003] Patent No. CN202320246251.2 proposes a multi-degree-of-freedom driving simulator based on mixed reality, including a control terminal, a multi-degree-of-freedom robotic arm, a seat platform and mixed reality glasses. Physical operating components are provided in the seat platform. The control terminal obtains the operator's operation of the operating components and controls the seat platform to simulate acceleration, constant speed, deceleration and turning. The mixed reality glasses obtain the real vision in the seat platform in real time and track the position and posture information of the operator when observing. The control terminal also generates a virtual vision, and fuses the real vision and the virtual vision to obtain a fused vision and sends it to the mixed reality glasses for display. The control terminal synchronously updates the rendering of the fused vision matching the position and posture in the mixed reality glasses according to the position and posture information when the operator observes. This utility model improves the real somatosensory effect of simulated driving.
