Embodiment Construction

[0042] The basic idea of ​​the embodiment of the present invention is to focus on the relationship between the connection or disconnection of the steering shaft and the clutch between the steering shaft and the shaft rotation speed, and allocate the rotation speed range for the continuous clutch idling state to the steer-by-wire control. For example, the rotation of the steering shaft is controlled as a normal state so that the clutch is idling. The steering shaft is disconnected from the steering shaft through the clutch idling, which can provide wire-controlled steering control. On the other hand, the clutch is connected when the rotation speed of the steering shaft decreases. Ensure the torque transmission from the steering shaft to the steering shaft, and give the steering control device fail-safe performance.

[0043] Among the steering control devices that have been proposed, it is only disclosed that the clutch is connected when there is an abnormality. In such a typical...

Abstract

The invention provides a steering control device for a vehicle. A steering control device for a vehicle includes: a steering unit having an input shaft; a steering unit having an output shaft; a clutch for connecting or disconnecting the input shaft and the output shaft; The control unit that controls the unit. The control unit controls the rotation of the output shaft so as to idle the clutch when the input shaft rotates. The clutch is configured to idle when the rotation speed of the output shaft is higher than the rotation speed of the input shaft, and to be connected when the rotation speed of the output shaft is lower than the rotation speed of the input shaft.

Description

Technical field [0001] The invention relates to a steering control device for a vehicle. Background technique [0002] For example, Patent Document 1 describes the use of a disconnection mechanism that switches the connection and disconnection between the input shaft and the output shaft to switch power transmission and non-transmission to mechanically separate the steering mechanism from the steering wheel and drive the steering according to the steering amount. The steering control device of the mechanism of the wire steering method. [0003] Patent Document 1: Japanese Patent Application Publication No. 2010-188930 [0004] In a vehicle with a wire-controlled steering system, it is preferable to implement appropriate failure countermeasures so that steering can be performed even when the wire-controlled steering system fails. Typically, multiple electrical systems and mechanical backup systems are proposed for this purpose. With multiple electrical systems, even if an abnormali...
