Abstract

Official abstract text for this publication.

A motor driven power steering (MDPS) may include: a vehicle speed sensor configured to sense vehicle speed; a temperature sensor configured to sense a temperature of a power pack; a current sensor configured to sense an amount of current applied to the MDPS; a storage unit configured to store a thermal resistance value based on the vehicle speed with respect to the temperature of the power pack; and a control unit configured to calculate an estimated temperature by reflecting the thermal resistance value based on the vehicle speed with respect to the temperature of the power pack and the current amount applied to the MDPS into a temperature estimation function, and drive a motor according to the calculated estimated temperature.

First claim

Opening claim text (preview).

What is claimed is: 1. A motor driven power steering (MDPS) comprising: a power pack comprising a motor and a control unit; a vehicle speed sensor configured to sense a vehicle speed; a temperature sensor configured to sense a temperature at the power pack; a current sensor configured to sense a current applied to the motor; and the control unit configured to calculate an estimated temperature using the current from the current sensor and a thermal resistance value that…
