Abstract

This paper gives an overview of uncertainty analysis of inertial measurement system intended for characterizing and comparing ground vehicle driving abilities in real world condition tests. For constructing measurement function and model, sources of system uncertainty are mapped and their effects described. Method finding acceleration sensor output systematic effects and standard deviation is discussed. Data processing algorithms add additional combined uncertainty to system, which can also be estimated. An overview of calibration method and experimental results are presented and eventually further accuracy improvements suggested.

Energy efficiency profiles for unmanned ground vehicles
Article

  • Apr 2019
  • P EST ACAD SCI
The paper investigates energy efficiency validation of unmanned ground vehicles (UGVs). The energy efficiency of the vehicle platform depends on the design elements and the environment as well as navigation algorithms. Verification of all UGV design factors that have measurable influence on energy efficiency involves an integrated measurement system for measuring the dynamic interactions of the vehicle and the environment during the real-condition test mission. Profiles are used for improving and optimizing the UGV design, control system, and comparison with each other. The obtained results are applied for the development, simulation, and testing library used as early-stage product design support.
