Description

The invention relates to a vehicle with a retractable steering device, comprising a holding element and a steering element for manually steering the vehicle.

From the DE 10 2012 014 762 A1 a motor vehicle with an instrument panel and a steering column arranged on a steering wheel is known, which is arranged in the region of the instrument panel. The steering wheel is movable relative to the instrument panel and slidable in a longitudinal direction of the steering column in the direction of the instrument panel from a first position to a second position. In an accidental application of force to the motor vehicle, the steering column is designed such that the steering wheel is moved from the second position to the first position.

The invention has for its object to provide a comparison with the prior art improved vehicle with a retractable steering device.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A vehicle includes a retractable steering device that includes a support member and a steering member for manually steering the vehicle. According to the invention, the steering device has a disk element, which is partially covered by the U-shaped handle elements formed with the steering element in the region of a pivot point of the steering element, a potentiometer for controlling an electric steering gear and the holding member is pivotally mounted on a movable carriage is.

Such a trained steering device is designed as a comparatively compact unit, which can be stored without great effort in a vehicle structure, design-optimized on an instrument panel.

By an exposed position of components of the steering device with respect to the instrument panel is a relatively good accessibility both in case of repair and in a need for manual operation of the steering device, for example in an emergency situation.

By means of a relatively simple pivoting kinematics everyday practicality and a short travel time of the electrically driven swivel kinematics can be largely ensured.

Embodiments of the invention are explained in more detail below with reference to drawings.

1 shows a partially transparent front view of a retractable steering device 1 for a vehicle not shown in detail with an assistance system for autonomous driving, in which the assistance system assumes a driving task in full.

Here is the steering device 1 in the present embodiment in 1 shown in a first embodiment.

In autonomous driving is the steering device 1 in an instrument panel shown in sections in the following figures 2 retractable, the steering device 1 If necessary, for example, in an emergency situation in a use position for a manual steering is movable.

The steering device 1 includes a steering element 3 , a holding element 4 and a disk element 5 ,

The steering element 3 is U-shaped and includes the circular running disc element 5 , wherein on the steering element 3 opposite gripping elements 6 are arranged, which can be ergonomically shaped.

At the steering device 1 it is a so-called electric potentiometer steering, for which purpose a potentiometer in a region shown by a dashed line on the holding element 4 is arranged, wherein in this area a pivot point of the steering element 3 located. In other words, it is in the steering device 1 not a steering coupled to a steering gear.

On the circular disc element 5 is a luminous thin-film element 7 made of organic semiconducting materials. The thin-film element 7 is designed to be touch-sensitive and can be operated manually with the desired insertion of operating elements by touching.

The circular disc element 5 is stable with the holding element 4 connected and remains at a rotation of the steering element 3 in his position. This points to the disc element 5 applied thin-film element 7 also a fixed position relative to a driver of the vehicle.

Will the disc element 5 however, with the steering element 3 coupled, it is necessary that the thin-film element 7 has a software readjustment, so that the display of controls by means of the thin-film element 7 also during a rotational movement of the steering element 3 relative to the driver have a fixed position, so remain in a vertical orientation.

For example, in the grip elements 6 or in a handle element 6 Functional elements to be integrated, which can be preferably operated with a thumb.

In manual driving of the vehicle is the disc element 5 , which can also be referred to as a monocle disc, in the viewing direction, ie arranged in the direction of travel of the vehicle, with a driving event without affecting driving safety even when an operation of the controls can be directly observed.

For example, an edge region of the disk element 5 designed as ambient lighting. Alternatively or additionally, at the edge region of the disk element 5 a Rahmeneinfassung be ordered.

2 shows a side sectional view of the steering device 1 in the first embodiment, wherein a movable in the direction of the longitudinal axis of the vehicle carriage 8th to which the retaining element 4 is pivotally mounted, is shown.

In the first embodiment, the retaining element 4 in the direction of travel x behind the disc element 5 arranged, wherein for stowing the steering device 1 So, to sink, the sledge 8th with the steering device 1 against the driving direction x moves and then about a pivot axis in the direction of travel x swings.

Is the steering device 1 stowed or sunk, is the disc element 5 essentially flush with the instrument panel 2 integrated or lies flush or flat on this.

As the retaining element 4 in the direction of travel x behind the disc element 5 is arranged, is the holding element 4 in the stowed state of the steering device 1 not visible because the retaining element 4 from the disk element 5 is covered.

As in 2 is shown are between the steering element 3 and the disc element 5 so-called felt glides 9 arranged so that a relative movement between the steering element 3 and the disc element 5 largely unhindered possible.

3 shows a second embodiment of the steering device 1 , wherein the retaining element 4 in front of the disk element 5 is arranged and for sinking or stowing according to the first embodiment by means of the carriage 8th movable and in the direction of the instrument panel 2 is pivotable.

Regardless of the embodiment of the steering device 1 This can be stowed manually and also electrically and also be positioned back into a position of use. An electric and uniaxial pivoting kinematics realizes a comparatively fast swiveling movement for positioning the steering device 1 in the position of use and is relatively robust designed for everyday use.
