Embodiment Construction

[0039] Some exemplary embodiments may be shown in the drawings in terms of functional blocks, units and / or modules, as is customary in the corresponding art. Those of ordinary skill in the art will understand that these blocks, units and / or modules are physically implemented by electronic (or optical) circuits such as logic circuits, discrete group components, processors, hard-wired circuits, memory elements, wired connections Wait. When the blocks, units and / or modules are implemented by a processor or similar hardware, they can be programmed and controlled using software (eg, code) to perform the various functions discussed herein. Alternatively, each block, unit and / or module may be implemented by special purpose hardware, or as special purpose hardware to perform some functions and a processor to perform other functions (eg, one or more programmed processors and associated circuitry) The combination. Each block, unit and / or module of some exemplary embodiments may be phy...

Abstract

A motor control apparatus and method of an electric power steering system are disclosed. A motor control apparatus for an EPS system of a vehicle includes: a temperature sensing unit configured to sense a temperature of a motor controller for controlling a motor in the EPS system; and an output control module configured to adjust a motor current applied to the motor from a steering control module of the EPS system based on the motor current and the temperature of the motor controller sensed by the temperature sensing unit.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to a motor control apparatus and method for an electric power steering (EPS) system of a vehicle, and more particularly, to a motor control device and method that can be used to control a motor based on a motor current and a temperature of a motor controller A motor control apparatus and method for an EPS system of a vehicle to regulate the output of the motor. Background technique [0002] An electric power steering (EPS) system for a vehicle is a steering apparatus that assists the steering force of a steering wheel through a motor. The EPS system uses inputs such as vehicle speed, steering column torque, absolute torque, absolute steering angle or vehicle state to control the torque of the motor used to assist the steering force of the steering wheel through the motor current. [0003] Typically, the EPS system measures the motor current input to the motor, reduces the assist steering torque of...
