Abstract
A vehicle speed control unit includes feedback control parts, the number of feedback control parts corresponding to the number of multiple motors, generating feedback command torques for the respective motors, on the basis of respective deviations between speed signals from speed sensors detecting revolution speeds of the multiple motors and feedback target vehicle-speed signal reshaped from the inputted target vehicle-speed signal by target vehicle-speed filters; a feedforward control part calculating a feedforward command torque for the vehicle as a whole, on the basis of the inputted target vehicle-speed signal; and a torque distribution part dividing the feedforward command torque into individual feedforward command torques for distribution to the respective motors, wherein the individual feedforward command torques are respectively added to the feedback command torques and, to control the respective motors.
