Abstract
An apparatus for controlling an electric steering system includes: a communication transceiver IC detecting an external operation signal while an ignition of a vehicle is off and outputting a wake-up signal through an internal communication network of the vehicle; and a processor, activated by the wake-up signal, controlling the electric steering system to automatically perform steering aging before a user enters the vehicle.
Claims13
An apparatus for controlling an electric steering system, the apparatus comprising:
- a communication transceiver integrated circuit (IC) configured to detect an external operation signal while an ignition of a vehicle is off and output a wake-up signal through an internal communication network of the vehicle;
- and
- a processor, activated by the wake-up signal, configured to detect weather information or temperature information, temperature inside the vehicle, and information on vehicle ignition-off duration from a sensor or a server included inside the vehicle and to control the electric steering system to automatically perform steering aging before a user enters the vehicle,
- wherein the processor is configured to determine, based on the weather information or the temperature information, the temperature inside the vehicle, and the information on vehicle ignition off duration, that grease is exposed to a low temperature environment in which viscosity resistance of the grease is at or above preset threshold viscosity resistance, and
- the processor is configured to perform the steering aging of the electric steering system based on a lookup table, which shows a relationship, pre-calculated through an experiment, between the detected information and the viscosity resistance of the grease.

A method for controlling an electric steering system, the method comprising:
- outputting, by a communication transceiver integrated circuit (IC), a wake-up signal through an internal communication network of the vehicle by detecting an external operation signal while an ignition of a vehicle is off;
- detecting, by a processor activated by the wake-up signal, weather information or temperature information, temperature inside the vehicle, and information on vehicle ignition-off duration from a sensor or a server included inside the vehicle;
- and
- controlling, by the activated processor, the electric steering system to automatically perform steering aging before a user enters the vehicle, when the processor determines, based on the weather information or the temperature information, the temperature inside the vehicle, and the information on vehicle ignition-off duration, that grease is exposed to a low temperature environment in which viscosity resistance of grease is at or above preset threshold viscosity resistance,
- wherein the controlling of the electric steering system to automatically perform the steering aging comprises:
- performing, by the processor, the steering aging of the electric steering system based on a lookup table, which stores a relationship, pre-calculated through an experiment, between the detected information and the viscosity resistance of the grease.
