INVESTIGATION OF THE EFFECTIVENESS OF THE ALGORITHM FOR CONTROLLING THE ACCELERATION AND DECELERATION OF A WHEELED VEHICLE BY MEANS OF A STROKE PEDAL

Abstract

Justification. Since one of the significant costs of operating vehicles is fuel costs, therefore it is very promising to use machines with electric drives, such as battery electric ones, which reduce these costs. The main key property for them is the amount of autonomous mileage on a single charge. To maximize this value, developers are trying to use more advanced, energy-intensive energy sources and reduce energy costs when converting it on the way from the source to the driving wheels. In this circuit, the traction electric drive is the main source of energy loss. Therefore, it is very important not only to use more advanced electric drives, but also to improve control algorithms. To do this, it is necessary to form the setpoints of the requested engine torque using only the stroke pedal, taking into account the speed of movement, other conditions, and vehicle characteristics. The implementation of such a law allows the driver to reduce energy consumption by controlling the car, allowing it to move by inertia (coasting) and maximize the use of regenerative braking with minimal use of the service braking system.The purpose of the work. Investigation of the functioning and efficiency of the algorithm for determining the torque settings of a traction electric drive using only the stroke pedal, using mathematical modeling methods.Materials and methods. The study was performed in the Matlab Simulink software package.Results. The article presents the theoretical foundations of constructing an algorithm for determining the torque setpoint of a traction electric drive, the results of a virtual efficiency study.Conclusion. The practical value of the study lies in the possibility of using the proposed law for determining the setpoint of the traction and regenerative torque of the traction electric drive, the run-out mode for the development of a traction drive control system for transport vehicles in order to increase their energy efficiency.
