Abstract
An electric vehicle motor control device controls the transmission of power from an electric motor to driving wheels via an automatic transmission. The electric vehicle motor control device includes a vehicle speed detecting device that detects a vehicle speed of the electric vehicle and a controller. The controller includes a required driving power calculating section that calculates a required driving power of the electric vehicle, and a target motor rotational speed calculating section that calculates a target motor rotational speed. The target motor rotational speed is calculated so that an efficiency of a product of a power consumption rate of the electric motor and a transmission efficiency of the automatic transmission will become a prescribed target efficiency, based on the vehicle speed and the required driving power. The controller controls the electric motor based on the target motor rotational speed.
