Definitions
- the invention relates to a level control device according to the preamble of claim 1.
- Today's vehicles are usually designed to offer the greatest possible passive safety in the event of a collision.
- measures are implemented in all areas of the vehicle to reinforce the vehicle elements and to absorb the greatest possible kinetic energy in the event of a collision.
- the object of the invention is to provide a level control device in which, in the event of a collision, an impact is ensured in a well-reinforced area of the vehicle.
- a detection device generates data of an object approaching relative to the own vehicle. These data can be, for example, the relative speed, the distance or the contour of an approaching object.
- the detection device can also evaluate data from a global positioning system (GPS), telematics data or other external data to determine the relative approach of a third-party vehicle.
- GPS global positioning system
- the processing device is designed such that it can reliably determine an impending collision from the data supplied by the detection device. Of course, an algorithm must be chosen that avoids false triggering as far as possible. It is advantageous to carry out the securing measures of a corresponding vehicle height adjustment in the event of a collision, for example, only if a collision with a certain strength is to be expected.
- the processing device If the processing device has determined an anticipated collision and localized the point of impact, it calculates an optimal vehicle height for the impending collision on the basis of the data supplied by the recording device. The vehicle height is calculated so that the collision occurs in the area of a vehicle part with a particularly high level of passive safety. If the vehicle is to be secured all around, at least four detection devices are required, namely in the front and rear areas and in the two side areas. The signal emitted by the processing device on the basis of the calculation is passed to the actuators, which carry out a vehicle height device in accordance with the calculations. -
- Fig. 1 is a schematic circuit diagram of an embodiment of a level control device according to the invention and in
- FIG. 2 shows a flow diagram for a method for operating the level control device in FIG. 1.
- the level control device in FIG. 1 represents a particularly simple embodiment of the invention.
- a control unit 10 is provided which receives signals from detection means.
- An image generation device (camera 12), a distance sensor 13 and a speed sensor 14 are provided as detection means in the present case. With all-round monitoring of the vehicle, appropriate devices should be provided on each side (front, rear, both sides).
- the control unit On the basis of this information, the control unit generates a signal which it forwards to the actuators A (16a to 16d) concerned.
- the actuators 16a and 16b have been selected as the actuators concerned, which set a vehicle height h '.
- the actuators 16c and 16d are not additionally acted upon.
- the flowchart in FIG. 2 shows a possible algorithm for the control device according to the invention.
- a first step the relative speed, the distance and the contour of objects around your own vehicle are continuously determined (S100).
- a collision calculation is then carried out in a step S102.
- step 104 it is decided whether a collision will take place. If a collision does not take place, the process branches back to step S100. If a collision takes place with a predefined safety, the area in which the collision will occur is calculated and the required vehicle height is calculated. Based on this result, actuator signals are generated (step S106), which are forwarded to the actuators concerned in step S108.
- step S110 After a certain time, it is checked whether a collision has occurred (step S110). If a collision does not occur, a reset is carried out in step S114 and a branch is made back to step S100. If a collision has occurred to a certain extent, the algorithm is ended.
- the present invention ensures in a simple manner an optimal use of the passive safety of a vehicle and can thereby reduce vehicle damage and minimize the risk of injury to occupants.
- the level control device according to the invention can also be used sensibly when parking to avoid damage to the vehicle.
