An object of the present invention is to provide a steering apparatus capable of improving a function of a bearing that supports a steering shaft. A steering apparatus includes a steering shaft, a first housing member, a second housing member, and a bearing. The steering shaft rotates according to a rotation of a steering wheel. The first housing member is located on one side in a rotational axial direction of the steering shaft, and includes a cylindrical portion and a flange portion. The cylindrical portion surrounds the steering shaft. The flange portion extends in a radial direction with respect to a rotational axis of the steering shaft to an outer side of the cylindrical portion in the radial direction. The second housing member is provided on the other side in the rotational axial direction, and forms a housing together with the first housing member. The second housing member includes a connection portion and a containing portion. The connection portion is connected to the flange portion of the first housing member. The containing portion contains a part of the steering shaft. The bearing is provided at a position that overlaps the flange portion in the rotational axial direction on an inner peripheral side of the cylindrical portion of the first housing member, and supports the steering shaft.

According to the disclosure, the steering control device and method may enhance the driver's steering feeling by correcting the steering torque due to a difference in linear distance despite a difference in the linear distance from the rotation axis according to the position of the pressure applied to the steering wheel shaped so that the linear distance from the rotation axis increases/decreases.

An electrode structure includes: a base material; a conductive fabric on a first surface of the base material; and one or more conductive wires on a second surface of the base material so as to be electrically insulated from the conductive fabric. The second surface is opposite to the first surface of the base material. The base material includes: a first area and a second area. The first area is fitted into a groove of the rim and the second area is placed in a part of a rim of a steering wheel other than the groove, when the base material is attached to the rim. The one or more conductive wires are arranged at a lower wiring density in the first area than in the second area.

A motor driven power steering control method may include setting a virtual friction model to a column connected between a steering wheel and a rack gear; calculating a frictional torque of the column by taking a steering angular speed of the steering wheel as an input parameter in the set virtual friction model; and calculating a target steering torque on the basis of a virtual steering system model using the frictional torque of the column as a parameter.

Method for detecting the presence of a driver's hands on the steering wheel is described. By a mathematical model, at least one part of a steering system of the motor vehicle is modeled. In addition, a rotational angle of a lower end and/or an upper end of a torsion bar of the steering system is determined. A torque acting on the torsion bar is determined by a measuring device. A sum of a torque with which the driver acts on the steering wheel and a counter-torque generated by friction in the upper part of the steering system is estimated by a Kalman Filter. In addition, the counter-torque is estimated, and the estimated sum of the torque and the counter-torque are used to determine whether the driver's hands are on the steering wheel.

An electromechanical power steering unit for a motor vehicle includes an integral component having a torque sensor unit, which detects the rotation of the upper steering shaft relative to the lower steering shaft. The torque sensor unit includes a ring magnet rotationally fixed to the upper steering shaft and a magnetic flux guide connected to the lower steering shaft. A magnet sensor detects the rotation of the shaft connected to the ring magnet with respect to the lower shaft connected to the magnetic flux guide and the ring magnet is carried by a ring magnet sleeve, which sits on the upper steering shaft and is made from a thermoplastic material and is molded by way of ultrasound forming in the upper steering shaft in one region for mounting on the upper steering shaft.
