MOTOR CONTROL METHOD OF ELECTRIC VEHICLE

摘要

PURPOSE: A motor control method of an electric car is provided to enhance the electric car by selecting a motor having high power efficiency according to running speed. CONSTITUTION: A first motor(110) runs a first wheel(210). A second motor(120) runs a second wheel(220). The first motor and the second motor have different power efficiency property. The first motor and the second motor are driven in case the driving mode of an electric car is in a 4 wheel driving mode. One either the first motor or second motor is driven according to running speed in case the driving mode of the electric car is in a 2 wheel driving mode. Power efficiency of the first motor is higher than the second motor in case the running speed of the electric car is less than or equal to pre-set speed. The power efficiency of the second motor is higher than the first motor in case the running speed of the electric car exceeds the pre-set speed.
