Title: Control device of electric power steering device
Inventor: ENDO SHUJI
IPC: B62D119/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To improve the responsiveness for the quick steering of a steering wheel by switching to a characteristic with a high gain out of plural steering vs a current order value characteristic at the detection time of a quick steering state in which the absolute value of the change rate of the steering torque is a prescribed value or more and the direction of the change rate coincides with the direction of the steering torque. SOLUTION: During a vehicle running, the change rate DT of a steering torque T from a torque sensor 10 is found out by a differentiator 41 in a quick steering state detection means 40 and when the output of an absolute value circuit 42 for finding out the absolute value of the change rate DT is a prescribed value C or more, a switch signal is outputted from a comparator 43. Meantime, it is discriminated by a direction discrimination circuit 44 whether the direction of the change rate DT is matched with the direction of the steering torque T and at the matched time, the switch signal SW is outputted from a gate 45 to a steering auxiliary order value calculator 32.  In other words, when the direction of the torque change rate coincides with the direction of the steering torque, the responsiveness at the quick steering time is raised by selecting so as to be a characteristic with a higher gain than the usual steering torque vs a current order value characteristic.

Abstract: PURPOSE:To eliminate an observation trouble due to the flow of a vertical stripe by driving the picture element of an odd-number column and the picture element of an even-number column with the video signal of a reverse polarity. CONSTITUTION:In the even-number field of an n-th frame and the even-number field of the (n+1)-th frame, picture elements 11 of the same polarity are arranged in a length-wise direction. Accordingly, the vertical stripe is generated in this field and further, between these fields, the picture element 11 to be driven by the video signal of a positive polarity and the picture element 11 to be driven by the video signal of a negative polarity are dislocated by one picture element in a horizontal direction. Accordingly, the vertical stripe is generated and this flows in a column direction together with the proceeding of the field. However, when the two field between these fields, namely, the odd-number field of the n-th frame and the odd-number field of the (n+1)-th frame are observed, the picture elements 11, to which the video signal of the same polarity is supplied, are not arranged in the length-wise direction but equally diffused over a whole screen. Thus, the degradation of picture quality due to the flow of the vertical stripe can be prevented.
