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.

A motor vehicle can include a steering hub mechanism and a steering wheel, the steering wheel can include an outer rim, a center section, and one or more modular accessories, and can include a first modular accessory configured to be fixed to the outer rim and a second modular accessory configured to be fixed to the outer rim, where the first modular accessory differs from the second modular accessory with respect to one or more of material, physical appearance, and/or a control function. The steering wheel can include one or more interchangeable spokes configured to be fixed to the center section and the outer rim, wherein said interchangeable spokes define the depth of the outer rim relative to the center section. The one or more interchangeable spokes comprise one or more control mechanisms, the control mechanisms being configured to attach to one or more attachment points of the outer rim.

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 vehicle control device includes an operation unit operated by a driver; and a controller that causes a vehicle to turn according to a movement of the operation unit and causes a height of the vehicle to be changed. The controller causes the height of the vehicle to be changed according to an upward or downward movement of the operation unit.

A driver seat airbag device, provided with a steering wheel and an airbag module. The steering wheel includes a variant rim with a central upper part thereof omitted, and a cover member that covers the module installation surface at the center of the rim and the airbag module. The cover member includes a frontal region on an occupant side of the airbag module, an upper region on the upper side of the airbag module, and a tear line that enables the frontal region and the upper region to open up as cover doors. The tear line extends continuously from at least the center of the frontal region to at least the center of the upper region. The cover doors open to the left and right respectively from near the center of the frontal region and upper region.

The steering heater 11 is provided on the surface of the skin material 23. The resistance value of the steering heater 11 is set to a level at which a heat quantity for heating the steering wheel 2 to a desired degree according to a voltage supplied from a power supply 32 which will be described later can be secured. The resistance value of the steering heater 11 is 1Ω or less, or the like, for example. When the resistance value of the steering heater 11 is set to 1Ω or less, for example, if the power supplied from the power supply 32 is about 13V, the heat quantity of the steering heater 11 is about 170 W and thus can appropriately heat the steering wheel 2.

Implementations include a display assembly for a switch assembly, comprising a display assembly touch overlay plate, wherein at least a portion of the display assembly touch overlay plate is comprised of a transparent or translucent material; a display, wherein the display is disposed underneath the display assembly touch overlay plate and wherein at least a portion of the display is visible through the portion of the display assembly touch overlay plate; a display assembly first housing and a display assembly second housing, wherein the display assembly touch overlay plate is in communication with the display assembly first housing, wherein a force applied to the display assembly touch overlay plate is at least partially transmitted from the display assembly touch overlay plate to the display assembly first housing to a switch assembly through a central portion of the display assembly first housing.

A method for friction coefficient determination on elastically connected subsystems, in which an overall system includes multiple subsystems and at least two subsystems are connected to one another by an elastic connection. The elastic connection has at least one static friction state and a sliding friction state for prescribed external state variables, in which the overall system is excited with a vibration having a variable excitation amplitude at a defined excitation frequency. The excitation amplitude is varied, in which a phase difference between the vibration and a measured reaction torque together with the excitation amplitude are recorded as a function of time, in which no phase difference occurs in the static friction state and a phase difference of 180° occurs in the sliding friction state. In a first step, the excitation amplitude is increased until a transition in the phase difference from 0° to 180° indicates the transition from the static friction state to the sliding friction state.
