摘要： In a motor control device (42) for a steer-by-wire steering device (10), the motor control device (42) having a redundant system consisting of two systems (L1, L2), a first turning current command value (It1) is calculated in a first system (L1), and a second turning current command value (It2) is calculated in a second system (L2). A third processor (68) outputs the first turning current command value (It1) when the two current command values (It1, It2) are not divergent and outputs the second turning current command value (It2) when the two current command values (It1, It2) are divergent. When a determination of a rapid steering operation is made, the third processor (68) outputs the first turning current command value (It1) regardless of whether or not the two current command values (It1, It2) are divergent.

摘要： Die Erfindung betrifft zwei Verfahren zum Erkennen einer Asymmetrie einer Fahrwerksgeometrie eines Kraftfahrzeugs sowie ein Verfahren zum Betreiben eines Kraftfahrzeugs. Bei dem ersten Verfahren zum Erkennen der Asymmetrie der Fahrwerksgeometrie wird eine Lenkinformation, welche eine Lenkung des Kraftfahrzeugs charakterisiert, zusammen mit einer ermittelten Bewegungskurve des Kraftfahrzeugs hinsichtlich eines Verziehens des Kraftfahrzeugs analysiert (V11), bei Ermitteln des Verziehens die Asymmetrie der Fahrwerksgeometrie festgestellt und eine Aktion des Kraftfahrzeugs ausgelöst, wobei die Aktion in Abhängigkeit von einer ermittelten Stärke des Verziehens ausgewählt wird (V12).

摘要： Provided is a power steering sensor assembly which is capable of maintaining a stable coupling between a sensing device and a housing without using a separate auxiliary member, and is mounted in an electric power steering system. The power steering sensor assembly includes a sensing device including a plurality of coupling projections formed on an outer circumferential surface thereof; and a first housing having the sensing device housed therein and including a plurality of coupling grooves formed on an inner circumferential surface thereof, the coupling grooves each having an upper end which is opened. When the sensing device is housed in the first housing, the coupling projections of the sensing device are inserted into the coupling grooves of the first housing, respectively, such that the sensing device is coupled to the first housing without being moved in a radial direction and an axial direction.

摘要： An electronic control apparatus includes a control unit 2; a plurality of power supply units 1-1, 1-2 for supplying the control unit 2 with power; and a power supply fault detector unit 3 for detecting a fault in the plurality of power supply units 1-1, 1-2. The control unit 2 operates in a normal mode on electric power supplied from the plurality of power supply units 1-1, 1-2, when none of the plurality of power supply units 1-1, 1-2 is faulty. If at least one of the plurality of power supply units 1-1, 1-2 is faulty, the control unit 2 operates in an energy saving mode in which less power is consumed on electric power supplied from the power supply unit that remains fully operational. Thereby an electronic control apparatus is obtained that enables continued operation during a faulty condition, while preventing circuit scale, dimensions, weight, and cost from increasing.

摘要： [Problem]
An object of the present invention is to provide an electric power steering apparatus that can suppress deterioration of steering feeling by changing a current command value of a normal system in motor control by two systems when an abnormality occurs in any of the systems.
[Means for solving the problem]
An electric power steering apparatus that calculates a current command value to a motor having two-system motor windings for each system, comprises a current command value adjusting section that calculates the current command value by using a steering assist command value and a compensation current command value; and the current command value adjusting section has a normal-time coefficient used at normal time and an abnormal-time coefficient used at abnormal time that are set to each system, a value obtained by multiplying a value obtained by adding the steering assist command value and the compensation current command value by the normal-time coefficient is the current command value when the two systems are normal, and a value obtained by adding the compensation current command value to a value obtained by multiplying the steering assist command value by the abnormal-time coefficient is the current command value to a normal system of the systems when an abnormality occurs in any of the systems.
