Mathematical modelling of the motion dynamics in the longitudinal direction of the electric vehicle

Electrification of vehicles drive affected their motion dynamics in both longitudinal and transversal directions, primarily the driving wheels slip during acceleration. The drive-wheel slippage is due to the maximum value of the electric motor driving torque during wheels acceleration. Another problem is low frequency vibration of mechanical parts of the propulsion system during step changes in electric motor torque. The paper presents an algorithm of the electric drive system interacting with the motion dynamics of an electric car.
