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.

Claim (Index 11):
A vehicle speed control unit comprising:\n a processor configured to: control multiple motors driving wheels of a vehicle provided with the multiple motors so that a speed of the vehicle follows a vehicle speed indicated by a target vehicle-speed signal being input, generate feedback command torques for feedback controlling the respective motors, on the basis of respective deviations between speed signals from speed sensors detecting revolution speeds of the multiple motors and a feedback target vehicle-speed signal reshaped from the inputted target vehicle-speed signal by target vehicle-speed filters, to feedback-control the respective motors, calculate a feedforward command torque for feedforward controlling the vehicle as a whole using a transfer function whose input is the inputted target vehicle-speed signal and whose output is a feedforward command torque for the vehicle as a whole, and divide the feedforward command torque into individual feedforward command torques for distribution to the respective motors, wherein the transfer function is a product of a transfer function of the target vehicle-speed filter multiplied by an inverse model of a transfer function of the vehicle whose input is a summation of forces in a direction of translational motion of the vehicle and whose output is the vehicle speed, and wherein the processor respectively adds the individual feedforward command torques to the feedback command torques for the respective motors, to control the respective motors.
