Abstract

The invention discloses a high-fidelity man-machine interaction driving test method and device based on digital twinning, and the scheme can comprise the steps: collecting the operation of a driver through a force feedback steering wheel and pedal equipment, generating an operation signal, receiving the operation signal through a data processing and control software environment, and converting the operation signal into a vehicle control instruction; and the digital twin model is sent to the vehicle dynamics simulation software, the simulation software carries out real-time dynamics calculation on the digital twin model according to an instruction and outputs vehicle state data, the data is subjected to byte packaging processing to form a binary data packet, and the binary data packet is synchronously sent to the three-dimensional graphic engine through a UDP protocol. The graphic engine analyzes the data packet and directly drives the vehicle model in the virtual scene to update the position, the posture and the wheel state according to the content of the data packet, and a built-in simple physical engine is not used in the process. According to the scheme, all software modules run at the same ip address or networking computing equipment, data interaction is achieved through a UDP protocol, and a driving test closed-loop platform with the human-machine-in-the-loop is jointly constructed.
