Abstract: A rotary angle sensor used to determine a relative angular position as compared to a reference position, comprising a housing (1), at least one rotor (3, 4) that is rotatably mounted inside said housing (1), one circuit board (2) containing electrical and/or electronic components as well as one or multiple stators corresponding to the number of used rotors (3, 4). The rotary angle sensor is supposed to be improved in such a manner that a particularly precise alignment of the first rotor (3) in relation to the stator is ensured and that it is inexpensive to manufacture. This is achieved by a first rotor (3) that is interlocked with the housing (1) without any play while a pre-loaded spring washer (14) is positioned on the latching arms (11).

Abstract: A vehicle steering control apparatus and vehicle steering control method make it possible to suppress a steering state of a steering operation element from being different from the driver's intention, in starting the driving source. A backup clutch, which is switchable between a release state where a torque transmission path is mechanically decoupled and an engagement state where the torque transmission path is mechanically coupled, is set to the engagement state in starting the engine. When the steering torque detected after the engine starts becomes equal to or lower than a clutch release start torque, the backup clutch in the engagement state is switched to the release state.
