Abstract

The method involves measuring a steering angle of guidable vehicle wheels (2) by using a steering angle sensor system (11,12). A steering wheel angle of a steering hand wheel (6) is measured by using a steering wheel angle sensor (13). A current steering wheel position of the steering hand wheel is adjusted with a current steering angle position of the guidable vehicle wheels.

Description

  • The The present invention relates to a method for adjusting a Suspension of a motor vehicle.
  • From the DE 10 2006 027 000 A1 For example, a method for determining the straight-ahead travel of a vehicle is known in which the vehicle is equipped with an acceleration sensor and a yaw rate sensor for carrying out a test drive. At the same time a steering wheel of the vehicle is connected to a steering wheel balance. During the test drive, the data of said measuring means are transmitted to an evaluation unit and evaluated directly or at a later time.
  • For the completion of a motor vehicle, it is necessary to Steering angle steerable vehicle wheels with the steering wheel angle to match a steering wheel. This can, for example, be achieved. that the vehicle drives straight when the steering wheel has its middle position. Such a comparison can, for example. be carried out with the help of a steering wheel balance, which for the adjustment process or for the adjustment of the chassis is connected to the steering wheel. However, this must be done with a relative be carried out with great care, reducing the time required this is relatively large.
  • The The present invention addresses the problem of for a method of the type mentioned in an improved embodiment Specify, in particular by a reduced effort distinguished.
  • This Problem is inventively by the subject of the independent claim. advantageous Embodiments are the subject of the dependent Claims.
  • The The invention is based on the general idea for determining the Steering wheel angle to use a steering wheel angle sensor, in a modern Vehicle is already present on the vehicle side. For example such a steering wheel angle sensor attached to a steering column, which carries the steering wheel. Through the proposed approach can be mounted on a separately mounted steering wheel on the steering wheel balance be waived. The time required for this Effort is unnecessary. Besides, that can be so changed Method performed with increased reproducibility become. To adjust the suspension can now be a steering angle the steerable vehicle wheels by means of a steering angle sensor which are expediently part of a Setting station is at the desired suspension setting is carried out. Furthermore, according to the invention the Steering wheel angle of the steering wheel detected with the steering wheel angle sensor become. Subsequently, the current steering wheel position of the steering wheel with the current steering angle position of the steerable Vehicle wheels are adjusted to what the desired Suspension adjustment possible.
  • Especially advantageous is an embodiment in which a Evaluation device of a setting station via a diagnostic interface of the vehicle communicates with the steering wheel angle sensor. The diagnostic interface and the steering wheel angle sensor are suitably in a vehicle electronics, in particular a vehicle electrical system, integrated.
  • Further important features and advantages of the invention will become apparent from the Subclaims, from the drawing and from the associated Description of the figures with reference to the drawing.
  • It it is understood that the above and the following yet to be explained features not only in each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.
  • preferred Embodiments of the invention are in the drawing and will become more apparent in the following description explained.
  • The only 1 shows a greatly simplified schematic diagram of a vehicle in a setting station.
  • Corresponding 1 includes a simplified illustrated motor vehicle 1 in the usual way steerable vehicle wheels 2 , z. Ex. Front wheels, as well as non-steerable vehicle wheels 3 , z. Eg rear wheels. The vehicle 1 also has a steering system 4 on, the simplified illustrated a steering column 5 which has a steering handwheel 6 carries over which a driver's steering wish in the steering system 4 can initiate.
  • The vehicle 1 can, for example, towards the end of its production in a setting station 6 be transferred, in which a chassis of the vehicle 1 is set. The adjustment station 6 includes, for example, an evaluation 7 , in particular a display 8th , a host 9 as well as an additional computer 10 may include. To adjust the suspension is a steering angle of the steerable vehicle wheels 2 with the help of a steering angle sensor 11 respectively. 12 detected. Furthermore, a steering wheel angle of the steering wheel 6 with the help of a steering wheel angle sensor 13 detected. The evaluation device 7 can now the current steering wheel position of the steering wheel 6 with the current steering angle position of the steerable vehicle wheels 2 compare.
  • In the steering angle sensor 11 these are vehicle-mounted sensors 11 , which are components of the vehicle 1 are. These internal steering angle sensors 11 of which each one each a steerable vehicle 2 is assigned, are in a vehicle electronics 14 integrated, which is a diagnostic interface 15 having. The evaluation device 7 communicates via the diagnostic interface 15 with the steering angle sensors 11 , In another embodiment, the alternatively provided steering angle sensor 12 a part of the adjustment station 6 form. The two external steering angle sensors 12 , each one of the steerable vehicle wheels 2 are assigned then are outside the vehicle 1 arranged and communicate, for example, via appropriate connection lines with the auxiliary computer 10 ,
  • The steering wheel angle sensor 13 is a part of the vehicle 1 , Appropriately, the steering wheel angle sensor is 13 Appropriately with the steering column 5 coupled, so he rotary actuations of the steering wheel 6 detected. The steering wheel angle sensor 13 is in the vehicle electronics 14 integrated, so that the evaluation device 7 via the diagnostic interface 15 with the steering wheel angle sensor 13 can communicate.
  • According to a particularly advantageous embodiment, the steering wheel angle sensor 13 in a jacket pipe module 16 be integrated, which is a part of the steering system 4 forms and which at least the steering column 5 includes.
  • To adjust the suspension or to adjust the steering wheel position with the steering angle positions, the evaluation 7 thus via the diagnostic interface 15 at least access a vehicle-side sensors, namely at least on the steering wheel angle sensor 13 , This makes it possible to dispense in particular with a steering wheel balance, which reduces the effort and improves the reproducibility of the adjustment process.
