Problems solved by technology

However, we have found that when the operation of the electric motors is stopped or the power consumption of each electric motor is reduced without special consideration while the vehicle is actually running, various functions realized by driving the electric motors (for example, the vehicle engine and electric power cooling of electrical components) will deteriorate and in severe cases may also adversely affect the engine or drive motor

Abstract

The present invention provides a method and system for controlling an electric motor, the method comprising the steps of: determining, by a controller, a state of charge of a battery configured to store power supplied to each of a plurality of electric motors; when the battery is charged When the state is equal to or less than a predetermined reference value, calculating, by the controller, current current consumption of each of the plurality of motors; and resetting, by the controller, the plurality of motors based on the current current consumption of each of the plurality of motors power supply to each of the electric motors.

Description

technical field [0001] The present invention relates to a method and system for controlling an electric motor, and more particularly, to a method and system for controlling an electric motor that can keep a vehicle running smoothly. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Typically, vehicles include different types of electric motors to perform various functions required for their driving. For example, a vehicle using an internal combustion engine includes an electric motor that drives a cooling fan for cooling coolant to cool the engine, or an electric motor that drives an AAF (Active Air Flap) for regulating air inflow. In addition, in an electric vehicle or a hybrid vehicle that is driven by using a driving force generated by a driving motor, the electric motor is applied to an EWP (Electric Water Pump) that circulates a coolant to cool ...
