Abstract
The authors of the article analyze the possibilities of correct diagnostics of unmanned and electric vehicles on modern power and inertia roller stands. The purpose of this work is to improve the quality of monitoring the technical condition of wheeled vehicles by providing highly informative and stable test modes of operation in the process of their diagnostics. To achieve this target, we have developed test methods for wheeled vehicles, the implementation of which it is proposed to use a hybrid designed stand allows to measure force and power to the drive wheels of the vehicle, and temporal and kinematic parameters of the process of its functioning. The study proved that, to ensure a highly stable and test modes of operation of wheeled vehicles in the process of control of technical condition and diagnosis, you should use hybrid stands.
Highlights
Our country's highways are actively developing electric vehicles and unmanned vehicles are already appearing
There are known studies aimed at studying the diagnostics of battery system failures in electric and hybrid cars [1-7]
More or less correct and informative parameters from the diagnostic point of view are provided by power stands
Summary
Our country's highways are actively developing electric vehicles and unmanned vehicles are already appearing. Experience suggests that the number of such cars will only grow every year. In the very near future, there will be urgent issues of maintaining and restoring their performance, providing high-quality diagnostics. There are known studies aimed at studying the diagnostics of battery system failures in electric and hybrid cars [1-7]. It is necessary to study the traction and speed properties of such vehicles. They do not have a driver who could formulate questions about the technical condition of wheeled vehicles, evaluate its traction-dynamic and braking properties, describe the problems of its units, components and systems
