Abstract
There is provided an electrically driven vehicle that well balances calculation volumes and communication volumes of two control devices configured to drive and control motors for driving. The electrically driven vehicle comprises at least one motor for driving and a first control device and a second control device configured to control the motor. The first control device is configured to calculate a target torque that is to be output from the motor, based on information including an accelerator position, to calculate a current command based on the calculated target torque, and to send the calculated current command to the second control device. The second control device is configured to use the current command, a phase current of the motor and a rotational angle of the motor such as to drive the motor by feedback control.
