Title: Steering system
Inventor: YOSHIDA TAKUJI
IPC: B62D6/00
Filed: 2020-10-12
Abstract: To improve a steering system, for example, to enable an abnormality in a conversion device to be detected by using a current flowing in an electric motor.SOLUTION: In the present steering system, for example, in a case where a current value which is the magnitude of a current flowing in an electric motor is larger than a set value or is large relative to an amount-of-movement-related amount which is related to the amount of movement of a steering shaft, it is detected that a conversion device is abnormal. For example, in the case of rust formation in the conversion device, the entry of foreign matter into the conversion device, or the like, friction force during the operation of the conversion device is increased, a load applied to the electric motor is increased, and the current flowing in the electric motor is increased. Thus, in the case where the current value of the current flowing in the electric motor is larger than the set value or is large relative to the amount-of-movement-related amount, it is possible to detect that the conversion device is abnormal. In other words, an abnormality in the conversion device can be detected by using the current flowing in the electric motor.SELECTED DRAWING: Figure 3

Abstract: To provide a circuit which is formed by one conductive type TFT and properly obtains an output signal amplitude.SOLUTION: A TFT is turned ON when an H level is inputted to CK1 and the potential of a signal output part (Out) is confirmed at an L level. Next, a pulse is inputted to a signal input part (In) and the H level is achieved and the gate potential of the TFT increases to (VDD-VthN), turning into a floating state. Consequently, the TFT is turned ON. Next, CK1 turns to the L level and the TFT is turned OFF. CK3 simultaneously turns to the H level and the potential of the signal output part increases, and as a result of a simultaneous increase of the gate potential of TFT102 to (VDD+VthN) or more through the action of capacity, the H level appearing at the signal output part (Out) becomes equal to VDD. When SP turns to Lo, CK3 turns to Lo, and CK1 turns to the H level, the potential of the signal output part (Out) turns to the L level again.SELECTED DRAWING: Figure 13
