DE102008008858A1 - Arrangement for detecting steering wheel angle during driving-dynamic checking of vehicle, has angle disk arranged with scale on steering wheel of vehicle, and light is projected from light source - Google Patents

Abstract

The arrangement has an angle disk (2) arranged with a scale (2.1) on a steering wheel (1) of a vehicle. Light (7) is projected from a light source (3) in a point-shaped or a line-shaped on the angle disk. A value corresponding to the steering wheel angle is marked and readable on the scale.

Description

The The invention relates to an arrangement for detecting a steering wheel angle during a vehicle dynamic examination of a vehicle.

driving dynamics Investigations on vehicles can For example, serve to a self-steering behavior of a vehicle at stationary roundabout or a steering wheel angle requirement for a single or double Lane change, as well as during slalom and when the vehicle in the Trap to determine a lateral slope. For this must a steering wheel angle are detected.

It is therefore an object of the invention, an arrangement for detecting a steering wheel angle in a dynamic driving examination of a Vehicle.

The The object is achieved by an arrangement with the features of claim 1.

advantageous Further developments are the subject of the dependent claims.

A inventive arrangement for detecting a steering wheel angle in a dynamic driving examination of a vehicle includes an angle disc with a scale that is arranged on a steering wheel of the vehicle, with light coming from a Light source substantially punctiform or linear so can be projected onto the angle disc, that one to the steering wheel angle corresponding value on the scale is marked and readable. The light source changed while their position relative to the vehicle is not while the angle wheel itself turns under the projected light, so depending on the steering angle with the Steering angle correlated values on the scale marked and readable are.

A such arrangement is without big Expenditure of time and costs in the vehicle mountable.

she can for Dynamic driving tests, for example in stationary circular drive used to determine a self-steering behavior of the vehicle. In a single or double lane change, as well as a Slalom or when running in the event of a lateral inclination a steering wheel angle requirement can be determined.

in the Below is an embodiment of the Invention explained in more detail with reference to drawings.

there demonstrate:

1 an interior of a vehicle with a steering wheel and an arrangement for detecting a steering wheel angle in a vehicle dynamics examination of the vehicle,

2 a bracket with three holders for attachment to a steering wheel rim,

3 an adjustable arm for locking a light source, and

4 a section of a scale provided on the angle plate with a graduation and a substantially punctiform light projection.

In 1 is an interior of a vehicle with a steering wheel 1 and an arrangement for detecting a steering wheel angle during a vehicle dynamics examination of the vehicle. The arrangement comprises an angle disk 2 , a light source 3 and an adjustable arm 4 , The angle disc 2 is with three on a diameter of a steering wheel rim 1.1 adapted and the steering wheel rim 1.1 partially enclosing holders 5 centered on the steering wheel 1 arranged. The light source 3 is at a first end 4.1 the adjustable arm 4 fastened, its second end 4.2 on a handrail connected to a body part of the vehicle 6 is attached. The adjustable arm 4 is set so that the light source 3 light 7 punctiform on a scale 2.1 projected on the angle wheel 2 is provided.

In 2 is the angle wheel 2 with the engraved scale 2.1 shown, which has a graduation. The holders 5 are also shown.

3 shows the adjustable arm 4 with a clamping device 8th for receiving the light source 3 at its first end 4.1 and a fastener 9 for fixing the second end 4.2 on the handrail 6 ,

4 shows a section of the on the Winkelscheibe 2 provided scale 2.1 with the graduation and the substantially point-like projected light 7 ,

The scale 2.1 may have a different classification, for example, grade or radians.

It can be a different, especially larger number of holders 5 be provided.

The light source 3 is in particular designed as a laser light source, as a point-like projection with high light output and correspondingly good readability is made possible. The laser light source may be of the type FP-65 / 1AE-AV-SD5-24V.

The Arrangement is in particular for use in a commercial vehicle suitable.

The light source 3 Can be supplied by means of an adapter from a cigarette lighter socket arranged in the vehicle with electrical energy.

The adjustable arm 4 can with his second end 4.2 be attached to the body or other body part.

For fixing the holder 5 on the steering wheel rim 1.1 is preferably provided in each case a rubber band with which the steering wheel rim 1.1 in the area of the respective holder 5 is encompassed.

The light 7 may deviate line on the scale 2.1 be projected, in particular substantially parallel to adjacent lines of the scale 2.1 ,

The scale 2.1 may differ in the angle disc 2 be arranged, for example by sticking a film.

The angle disc 2 may be formed differently from the circular shape shown.
