Abstract

A drive control system for an electric motor includes a slippage determination device, a tentative vibration damper torque calculator, a vibration damper torque limit value setting device, a vibration damper torque setting device, and a control device. The vibration damper torque setting device is configured to set a control torque obtained by limiting a tentative vibration damper torque using a limit value set by the vibration damper torque limit value setting device. The control device is configured to control driving of the electric motor in accordance with a command value of a torque obtained by combining a requested torque for the electric motor with the control torque set by the vibration damper torque setting device.
