Title:
ELECTRIC VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/055572
Kind Code:
A1
Abstract:
This electric vehicle control device calculates the shaft speeds of a plurality of motors respectively, calculates a reference speed on the basis of the calculated shaft speeds, monitors the detecting states of the shaft speeds to output a state signal, and switches the control means of inverters which control the respective motors by the following controls: acceleration detection control which restricts torque by calculating a torque restriction amount according to the temporal variation ratio of the shaft speeds of the motors on the basis of the state signal; and slipping speed control which restricts torque on the basis of the difference between the shaft speeds of the motors and the calculated reference speed.
