Investigation of the efficiency and effectiveness of the algorithm for suppressing self-oscillations at the intensive start of movement on the rise

One of the possible operating modes in which the self-oscillation of the shafts and gears of the traction electric drive are most pronounced is the mode of fixing the vehicle on a slope at the beginning of its rolling due to the creation of torque on the shafts of electric motors that prevent the wheels from rotating towards the rolling of the vehicle. At the same time, the standard braking system is activated, and the driving wheels are in braking mode, since the lifting assistance function is activated. In this case, there may be inconsistency in the processes of reducing the braking torque and increasing the traction torque at start, which can lead to the accumulation of energy in the system exciting self-oscillations with negative friction and the absence or smallness of damping. This operating mode in operation is highly probable, since the movement of the vehicle is always associated with stops and the subsequent start of movement, especially in populated areas, which often happens on road slopes. The purpose of the study. It is necessary to check the operability and effectiveness of the self-oscillation suppression method in the electromechanical wheel drive system at the beginning of movement and the operation of the lifting assistance system.
