Embodiment Construction

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a schematic diagram for explaining the configuration of a steering device for a vehicle according to an embodiment of the present invention, and shows the configuration of a steer-by-wire system. This vehicle steering device 1 includes a steering wheel 2 , a steering motor 3 , and a steering device 4 . The steering wheel 2 is a steering member operated by the driver for steering. The steering motor 3 is driven corresponding to the rotation operation of the steering wheel 2 . The steering device 4 transmits the driving force of the steering motor 3 to the front left and right wheels 5 as steered wheels. There is no mechanical connection between the steering wheel 2 and the steering mechanism 6 including the steering motor 3 and the like that mechanically transmits the operating torque applied to the steering wheel 2 to the steering mechanism 6 . ...

Abstract

In a vehicular steering system, a steering wheel (steering member) operated for steering and a steering operation mechanism are not mechanically coupled together, and the steering operation mechanism is driven by a steering operation motor. The vehicular steering system includes a reaction force motor that applies a reaction force to the steering member, and a reaction force motor control unit that controls the reaction force motor. The reaction force motor control unit includes a torque limiter that limits a current flowing through the reaction force motor to a predetermined value or smaller during automatic operation.

Description

technical field [0001] The present invention relates to a steering device for a vehicle that drives a steering mechanism by a steering motor without mechanically coupling a steering member operated for steering to a steering mechanism. Background technique [0002] There has been proposed a steer-by-wire system in which the mechanical coupling between the steering wheel and the steering mechanism is eliminated, and the driving force of the steering motor controlled in accordance with the operation of the steering wheel is transmitted to the steering mechanism. A parking assist device (Parking assist device) has been proposed that automatically parks a vehicle at a target parking position without requiring the driver to turn and manipulate the steering wheel during parking such as parking in a garage or tandem parking. [0003] In a vehicle equipped with a steer-by-wire system, when parking assistance (automatic steering) is performed by the parking assist device, the steerin...
