Ensuring vehicle safety by means of tyre characteristics improvement
EDN: ZAXZJL
Abstract
Introduction (problem statement and relevance). One of the major challenges of our age is to decrease the greenhouse emissions produced by motor vehicles. There is some practice of imposing a number of restrictions on operation of vehicles equipped with internal combustion engines (ICEs), which is aimed to reduce the amount of fuel burnt and emissions into the atmosphere. Despite this, ICE vehicles will still make up a significant proportion of the European vehicle fleet. Electric powertrain vehicles have been proposed as a replacement, but their limited cruising range is one of the reasons for their slow spread. Both of these problems can be solved by energy-efficient control of the motion process.
The purpose of the study is to test the system of energy-efficient control of longitudinal motion of the connected highly automated vehicles in the modern megalopolis environment, considering the terrain, speed modes and traffic lights operation modes.
Methodology and research methods. Laboratory testing of the developed mathematical model has been performed on a digital twin of a test road section reproduced using high-accuracy navigation data based on the example of an ICE passenger car.
Scientific novelty and results. The laboratory testing results show that the proposed system of energy efficient control of vehicle longitudinal motion is by 4.5% more energy-efficient than that of a vehicle with cruise-control. The system developed can be integrated into the connected highly automated vehicles to increase their energy efficiency.
