FIELD: transportation.
SUBSTANCE: method for controlling drivetrain play consists in switching the transmission to a gear, which allows the electrical machine connected to the transmission to operate at a rotation speed lower than the base rotation speed of the electric machine in response to the reduction in torque required by the driver. Then, a stroke of the gear tooth against the gear tooth is attenuated by actuating the electric machine in the rotation speed control mode when the drivetrain torque is switching from the negative torque to the positive torque.
EFFECT: shock-free engagement of gear teeth.
