US 2026/0241981 A1 · VEHICLE STEERING APPARATUS

Abstract

A vehicle steering apparatus includes a rotatable nut operably coupled to a rack bar and sliding the rack bar in an axial direction, a first nut pulley provided on an outer surface of the rotatable nut, a second nut pulley provided on the outer surface of the ball nut, a first motor pulley coupled to a first motor and connected to the first nut pulley via a first belt, a second motor pulley coupled to a second motor and connected to the second nut pulley via a second belt, an angle sensor accommodated in a steering column and coupled to a steering shaft, detecting a rotational angle and/or direction of the steering shaft, and transmitting the detected rotational angle and/or direction as an electrical signal, and a controller controlling the first and second motors based on the electrical signal received from the angle sensor.

Dependent claims

A vehicle steering apparatus, comprising:

a rotable nut operably coupled to a rack bar and configured to linearly move the rack bar by rotation of the rotatable nut;
a first nut pulley provided on an outer surface of the rotatable nut;
a second nut pulley provided on the outer surface of the rotatable nut;
a first motor pulley of a first motor operably connected to the first nut pulley through a first belt;
a second motor pulley of a second motor operably connected to the second nut pulley through a second belt;
an angle sensor included in a steering column, positioned around a steering shaft, and configured to detect a rotational angle and/or direction of the steering shaft and transmit a signal indicative of the detected rotational angle and/or direction of the steering shaft;
and
a controller configured to control the first and second motors in response to the signal indicative of the detected rotational angle and/or direction of the steering shaft.
