Abstract

BACKGROUND: Modern battery-powered vehicles still do not meet the needs of consumers in terms of autonomous mileage. Therefore, the problem of increasing the energy efficiency in order to reduce energy consumption for motion is highly relevant. One of the directions, along with the use of more efficient units and systems, is the development of control algorithms that minimize these costs and make it possible to control the motion using only the accelerator pedal.

AIM: The study of the operability and effectiveness of the algorithm for controlling a vehicle only with an accelerator pedal using virtual simulation of motion, further practical implementation of the algorithm in the control system.

METHODS: The study was carried out using the MATLAB/Simulink software package.

RESULTS: The paper describes the functioning of the single-pedal control algorithm using the example of a passenger vehicle with an individual traction electric drive, the results of virtual simulation proving its operability and energy efficiency for the case of highway traffic.

CONCLUSION: The practical value of the study lies in the proven operability, energy efficiency, and the possibility of using the algorithm for development of the software for vehicle motion control systems.
