The present invention relates to a method for controlling a chassis control system of a motor vehicle and a chassis control system for a motor vehicle.

Motor vehicles, especially mass means of transportation and means of transport such as passenger cars (cars, buses) and trucks (trucks) are with a particular

Currently there is the possibility for the driver of a motor vehicle, a vehicle setup by means of suitable

Adjusting means to suit your own needs. Here, on the basis of the setting means, which may be a mechanical selector switch in particular or else an electronic menu-driven selection, it is usually possible to select from different modes. The various modes differ in addition to setting various characteristics for the throttle and the steering also by different suspension settings, which can be adapted to the needs of the driver. Also known as adaptive chassis, in which individual components of the chassis can be adapted to the current road conditions, thereby for a desired driving feel and / or

Road condition due to the time required for sensory detection of change, another

Processing and active adaptation of the relevant suspension components relatively slowly. The regulation itself is therefore always behind the current road conditions, because since the road condition can not be predicted, a suspension setting always takes place delayed. As a result, the suspension can temporarily be set inappropriate for the current road condition, so that a corresponding phase in the current

set vehicle setup does not lead to the desired driving experience on a currently available roadway situation. For example, if a short bumpy section is discovered on the road, the landing gear may be too hard at first, and the landing gear will be too soft for a certain overrun time after passing the bumpy section until the control algorithm recognizes, that it can be set to a changed state again.

Therefore, it is desirable a possibility

In addition, a supplement to the data stored in the data server and / or information is provided with further information received from the data server. This supplementation of the data and / or information takes place for example by means of a so-called

Data fusion algorithm, which receives the received data from motor vehicles that have a specific

Fig. 3 shows a schematic representation of a system for carrying out a proposed

Method, according to an exemplary embodiment of the invention.

The illustrated system is discussed in more detail below from the perspective of the data server 2. The Possibility to preview the suspension setup

To be able to adapt the road situation, that is to say in the

Prior to a change in the roadway properties is provided by the exemplary embodiment of a system according to FIG. 3 and proceeds as follows:

In general, it should be noted at this point that subsequently there is a change in the condition of the roadway of the illustrated roadway section 5 due to the presence of a pothole 7, but in general it can be a variety of possible causes, such as a wavy surface, black ice and / or Impurities, and / or other conditions

act.

In the situation illustrated in FIG. 3, the first motor vehicle 6 a and the second motor vehicle 6 b have already passed the pothole 7. The second

Motor vehicle 6b is situationally still in the area of the pothole hole 7. The first and second

Motor vehicle 6a, 6b have a built-in

Roadway sensors the road conditions, especially the

Changes in the road condition through the pothole 7, detected by appropriate measurements, in particular detected, and as described above reactively adaptive chassis, preferably at least one suspension component, adapted to the road situation. Among other things, the following data and / or sensory measured variables may be relevant for this: the shock absorber activity, in particular a change in length of the shock absorbers,

Rule data of an electronic stability program and / or an antilock braking system, in particular in

Brakes, as well as measured data carried over

Steering movements, for example in a serpentine drive. However, information about the weather, especially the weather conditions such as rain, hail, black ice, a wet road, or even a

manual change of the driving mode by the driver, or a speed change of the motor vehicle are detected.

In addition, transmit the first and the second

Motor vehicle 6a and 6b, the detected second

Roadway texture information on a

Communication network 3 to a data server 3. This

Data server 3 is preferably set up to provide a cloud database and functions as a

so-called backend service, which collects the data about the second road condition information sent exemplarily from the first and second motor vehicles 6a, 6b. For the transmission itself, the first and second motor vehicle 61, 6b is responsible, for example via a built in the engine control

Communication unit 14 and / or via a

Mobile telephone, which with a corresponding electronics of the first and / or second motor vehicle 6a, 6b

is connected. In the data server 2, the transmitted second road condition information of the first and second motor vehicles 6a, 6b is received and further processed.

By means of a data fusion algorithm, the data from the first and second motor vehicle 6a, 6b and

optionally further not shown

Motor vehicles that have passed the lane section 5 fused and plausibility, that is, they are preferably based on edge information such as

Location information and / or time information with each other connected. In particular, it is assumed that a sufficient number of motor vehicles on

Lane section 5 corresponding

Roadway texture information is sending.

The prerequisite for this is, of course, that each message with a time information, in particular a time, and a geometric dimension of the lane section 5 with the changed road condition, in particular the pothole 7, is occupied, and the data server 2 of each of the first and / or second motor vehicle 6a , 6b by position determination knows where it is. From this data, the data fusion algorithm can determine if, where and how long the road has a corresponding one

Condition with a modified roadway texture has.

Approaches a subsequent third motor vehicle 6c the road section 5, so this third

Motor vehicle 6c on time the second

Road condition information of at least one of the preceding motor vehicles 6a, 6b are transmitted. As shown, this can be first

Roadway texture information about that

Communication network 3 are received by the data server 2. These first received in this way

Road condition information may consist of a plurality of second road condition information sent from other vehicles to the data server 2.

Alternatively and / or additionally, these second roadway condition information may also be transmitted directly from one of the preceding vehicles to the third

Motor vehicle 6c are sent. As shown

this happens for example from the second Motor vehicle 6b, which is within range of a short-range radio signal usable for this purpose.

The third motor vehicle 6c can then already in

Advance the chassis settings adjust so that they are the best possible on the road condition, especially on the pothole 7, set to this without

Impairment of driving characteristics to happen. This can be done for example by an automatic change of the driving mode. When the third motor vehicle 6c approaches the pothole 7, the driving mode is automatically changed. Example: If the third motor vehicle 6c is currently driving in "Sport" mode and gets the information that a pothole 7 is coming in 300 m, then that can

Chassis control system 1, preferably in an adapted short distance before the pothole, in particular about 10 m before, automatically switch to the mode "Normal" or "Comfort".

Such a landing gear mode may in particular be selected from a group provided

Chassis modes, such as: One or more eco-friendly and fuel-saving, so-called economy modes, a normal mode, a comfort mode, and one or more sport modes.

It is also conceivable that a variable adaptation of the current mode takes place. Here, the current drive mode is maintained, however, for example, the attenuation may be varied within a certain variable range around a predefined configuration.

A combination of the two aforementioned methods is also feasible. This means that the mode can be changed automatically, as well as a variance around a fixed configuration value of the changed mode be allowed around. In the maximum case, the

Variances of different modes are chosen overlapping, so that the at least one suspension component 13 in principle free and continuously to the respective

Road condition can be adjusted.

If, for example, it turns out that a first road condition information received from the third motor vehicle 6c is no longer up to date by the data server, then the third motor vehicle 6c also reports this to the data server, whereby this message is then taken into account again in the fusion algorithm and thus no longer current

Road condition information is not sent to other motor vehicles.

In addition, it is pointed out that the further inventively proposed disk 4

for example, by that shown in Fig. 2

Information memory 110 alone, or in conjunction with the example formed in the form of an electronic IC module data processing unit 11 may be formed. However, it is also conceivable that the data carrier 4 in the form of a compact disc, not shown, or an alternative storage medium, such as

for example, a USB stick or the like

is trained. LIST OF REFERENCE NUMBERS
