Problems solved by technology

[0004] Due to the lack of mechanical connection between the steering shaft and the wheels, traditional steer-by-wire devices cannot transmit to the driver the sense of weight caused by the friction between the wheels and the road surface or the wheels are stuck, resulting in poor steering feel, and although the wheels are stuck due to On e.g. curbs where no further rotation is possible, the steering wheel can still be rotated

Abstract

According to the present embodiments, torque caused by friction when a steering shaft rotates is applied so as to provide weight to the operation of a steering wheel by a driver, and the steering shaft is restricted from rotating in certain situations in which wheels can no longer rotate, such as when the wheels are caught on a curb, thereby enabling the steerability and steering stability of the driver to be improved.

Description

technical field [0001] The present embodiment relates to a steering device for steer-by-wire, and more specifically, relates to a steering device for steer-by-wire as follows: when the steering shaft rotates, friction torque can be applied for the driver to operate the steering wheel Provides a sense of weight and can limit the rotation of the steering shaft in situations where the wheel is no longer spinning, for example due to jamming on a curb, thereby enhancing steering feel and stability for the driver. Background technique [0002] Steer-by-wire is a type of electric steering that uses electricity to steer the vehicle without any mechanical connection, such as a steering column or universal joint, between the steering wheel and the front-wheel steering. [0003] In other words, the driver's manipulation of the steering wheel is converted into an electrical signal, and the electronic control unit receives the electrical signal and determines the output of the motor acco...
