摘要： Intended is to solve the problem of an increase in the cost of an electric power steering control system, the oscillations of which are suppressed by estimating and feeding back the oscillation frequency components of a motor rotating speed through an observer from a steering torque signal and a current signal for driving a motor, no matter whether a phase compensator might be made of an analog circuit or a software. In order to solve this problem, there is provided the electric power steering control system, in which the phase compensator of the steering torque is made of an analog circuit and in which an anti-phase compensator is made over the software of a microcomputer, thereby to eliminate the changes in the gain and the phase by the phase compensator of the analog circuit near the oscillation frequency, so that the steering torque signal equivalent to that of no phase compensation necessary for the computation at the observer is computed from the phase-compensated steering torque signal.

摘要： A lane recognition image processing apparatus can improve lane marking recognition performance by preventing false detection by addition of a condition without changing the basic principle of an one-dimensional image filter. A search area is set for each lane marking with respect to images stored in a image storage part through a window. A candidate point extraction part extracts candidate points of each lane marking from the search area thus set. A lane marking mathematical model equation is derived by approximating sets of extracted candidate points by a mathematical model equation. The candidate point extraction part includes a kernel size setting part, a filtering part that outputs, as a filtering result, the smaller of differences between the gray value of a pixel of interest and those of pixels forwardly and rearwardly apart a kernel size from the pixel of interest in a scanning direction, respectively, and a binarization part that binarizes the filtering result.
