Abstract: BACKGROUND: The current trend of using electric buses has been growing in the last few years. Articulated electric buses also take the routes. These vehicles, due to the presence of heavy traction batteries mainly on the roof, have a tendency to an increased roll angle and a tendency to rollover. Therefore, there is a need to apply anti-rollover measures for such vehicles. AIM: Development of the control law and algorithm that are capable of decreasing the tendency of an articulated electric bus to rollover by means of reducing the torque. METHODS: During the development and research of the algorithm, the MATLAB/Simulink simulation environment with the developed mathematical model of spatial motion of an articulated electric bus is used. RESULTS: The derivation of formulae for calculating the critical turning velocity of sections for articulated vehicles is presented, an algorithm and a traction control law are formulated depending on the turning parameters, the graphs that justify the operability and effectiveness of the algorithms are presented. CONCLUSION: The practical value of the developed algorithm lies in its practical application on an articulated vehicle in order to reduce the tendency to increased roll angles and to protect it from rollover.
