Multiparametric analysis of a mimicked accelerating pedal (Via DC Motor) of an electric vehicle.

In this 21st century, researchers have been exploring different designs, performance characteristics, charging-discharging regions, and regenerative braking aspects of electric vehicles. However, there has been a major gap in the multimodal analysis of the accelerating pedal drive for electric vehicles; therefore, herein, the novel analytical model of a mimicked foot pedaling control of the electric vehicle is developed by cascading five sub-models (i.e., Foot Pedal, Resistive Potentiometer, 555-Timer, Buck-Converter, and the permanent magnet DC Motor) to synthesize the overall 3rd order transfer function of the system. MATLAB is utilized to comprehensively analyze the transient and steady-state characteristics of the developed model by considering the Pedaling force, four different materials (i.e., Aluminum, Brass, Carbon Fiber, Polyamide 6), Potentiometer’s resistance, mechanical and electrical attributes of the motor. Results highlight that the linear pedaling drive is possible by considering Polyamide 6 material at pedaling properties of 0.25 kg Mass and 2.679 Ns/m Damping Coefficient. Furthermore, at a lesser potentiometer track length (around 10 cm) and equivalent inertia of 5 Kgm², the motor generates the regulated angular speed, thereby minimizing the transient characteristics in the accelerating pedal.
