Apparatus and method for stabilizing steering feel in motor-driven power steering

摘要

An apparatus for stabilizing a steering feel in a motor-driven power steering (MDPS) includes: an input unit configured to receive a column torque of a steering wheel; a calculation unit configured to convert the column torque signal inputted from the input unit into a target signal for generating a compensation signal of the steering wheel; and a compensation unit configured to calculate an assist torque for compensating for a main assist torque based on the target signal from the calculation unit.

主权项

1. An apparatus for a motor-driven power steering (MDPS), the apparatus comprising:
a main assist toque logic configured to provide a main assist torque signal based on a column torque signal indicative of torque applied to a steering wheel; a compensation assist torque logic comprising a high-pass filter and configured to generate a compensation assist torque signal, wherein in the compensation assist torque logic, the column torque signal is applied to the high-pass filter to remove low frequency components in the column torque signal, wherein the compensation assist torque logic does not comprise a low-pass filter; and a control logic configured to combine the main assist torque signal and the compensation assist torque signal for compensating the main assist torque signal to control a steering motor of the motor driven power steering.
