Patent ID: 7357204

Claim:
A drive-control-system of an electromotive vehicle having comprising: a vehicle-drive system comprising a driving motor mechanically linked with a driving wheel; a position sensor detecting a rotor position that is a position of a rotor of the driving motor; a driving-motor-angular acceleration calculation-process unit calculating an angular acceleration of the rotor based on the rotor position detected by the position sensor; a damping-control-process unit controlling the driving motor such that the angular acceleration of the rotor becomes zero; a condition-determination-process unit that reads a vibration index as a factor causing vibration in the vehicle-drive-system, and determines whether a damping-control-starting-condition is established based on the vibration index; and the damping-control-process unit that performs a damping control process when the damping-control-starting-condition is established and that prohibits the damping control process when the damping-control-starting condition is not established.
