Embodiment Construction
[0058] The present application will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0059] see figure 1 As shown, the embodiment of the present application provides a method for adaptive calibration of control parameters of a parallel driving vehicle, which is implemented based on a 5G network. The adaptive calibration method includes steps:
[0060]S1. The driving simulator sends the simulated signal parameters to the parallel driving controller.
[0061] Wherein, the driving simulator is connected to the server through USB (Universal Serial Bus, Universal Serial Bus), and both the driving simulator and the server are located at the cockpit end of the parallel driving background. The server provides drivers for the driving simulator, converts its analog signals into network signals, and connects to the 5G private network segment through Ethernet.
[0062] S2. The above-mentioned parallel driving controller controls the ...

The present application discloses a method and system for adaptive calibration of control parameters of parallel driving vehicles, and relates to the technical field of control parameter calibration. The method includes: the driving simulator sends the simulated signal parameters to the parallel driving controller; Simulate the signal parameter driving, and obtain the driving data and send it to the server; the server builds a Kalman filter prediction model based on the vehicle parameters and driving data, takes the driving data as the observation quantity, and obtains the vehicle end quality and slope value as the prediction result in real time, and The prediction results are transmitted to the parallel driving controller; the parallel driving controller constructs the calibration equation between the analog signal parameters and the vehicle control parameters, and calibrates the vehicle control parameters in real time according to the driving data, vehicle end mass and slope value. In this application, the vehicle control parameters are calibrated in real time in combination with the quality of the remote controlled vehicle and the slope information of the road, so that the remote driver can control the vehicle safely and efficiently.
Description
technical field [0001] The present application relates to the technical field of calibration of control parameters, in particular to a method and system for adaptive calibration of control parameters of parallel driving vehicles. Background technique [0002] The original idea of parallel driving was formed in the mid-1990s. In recent years, with the development of technologies such as the Internet, big data, cloud computing, Internet of Things, and artificial intelligence, the development of parallel driving has also been promoted. The vehicles in the parallel driving system can be various types of vehicles, such as manned sightseeing vehicles, unmanned vending vehicles loaded with goods, engineering vehicles, etc. [0003] In the related art, the relationship between the simulated parameters of the parallel cockpit rig and the control parameters of the actual controlled vehicle is usually determined directly by means of a real vehicle test, and then parallel driving is p...
