Remote cockpit applied to parallel driving system

Abstract

The invention discloses a remote cockpit applied to a parallel driving system. The remote cockpit comprises a host, a G-force dynamic platform, a force feedback steering base and a simulation steering wheel, the host is used for adjusting the motion state of the G-force dynamic platform in real time according to the IMU information of a controlled vehicle so as to simulate the body posture of the controlled vehicle through the motion state of the G-force dynamic platform; and the host is also used for acquiring the steering torque and vibration frequency of the steering wheel of the controlled vehicle according to the angle data and the vehicle speed data of the steering wheel of the controlled vehicle, and controlling the angle and vibration of the simulated steering wheel through the force feedback steering base so as to simulate the steering torque and vibration of the steering wheel of the controlled vehicle. According to the invention, the real and comprehensive feedback of driving environments such as bumping and vibration generated when the controlled vehicle passes through the road surface can be realized, the construction cost is reduced, and the deployment period is shortened.

Description

technical field [0001] The invention relates to the technical field of parallel driving, in particular to a remote cockpit applied to a parallel driving system. Background technique [0002] With the continuous improvement of the economic level, cars have gradually entered thousands of households and become one of the most common commodities. At the same time, with the development of automobile intelligence and networking, practitioners have made a lot of valuable explorations on unmanned driving technology that can greatly relieve human driving fatigue and improve driving safety. However, the current unmanned driving technology is not yet fully mature, and there is a certain probability of systemic failures during the operation process. Therefore, a parallel driving system that can take over the unmanned driving system when the unmanned driving system fails has emerged as the times require. [0003] Parallel driving is a driving method in which the driver and the controlle...

AI Technical Summary

Problems solved by technology

[0005] 1. The main function of the six-degree-of-freedom dynamic platform is to keep the attitude of the master vehicle consistent with the real-time attitude of the controlled vehicle. Although it can truly feed back the bumps and vibrations generated by the controlled vehicle passing through the road to the remote cockpit, it lacks steering wheel steering Torque feedback and steering wheel vibration feedback

[0006] 2. The six-degree-of-freedom dynamic platform is based on the upgrading and transformation of existing vehicles and six-degree-of-freedom platforms. Existing vehicles of different models need to be re-matched with six-degree-of-freedom platforms. The transformation and deployment period is long and the efficiency is low. The six-degree-of-freedom dynamic platform needs to be applied to existing vehicles, so the construction cost is high, which is not conducive to the promotion of parallel driving technology

[0007] To sum up, parallel driving in the existing technology is still in the development stage, and the remote cockpit cannot provide comprehensive and true feedback on the driving experience, and the construction cost is high and the deployment efficiency is low.
