Abstract

A method for controlling a pneumatic spring assembly of a motor vehicle includes deriving discrete condition parameters from a condition of the motor vehicle, wherein the discrete condition parameters are combined into parameter sets. Each parameter set is furthermore associated with a defined height control behavior, and wherein a height control behavior that is associated with a specific condition of the vehicle is set by activating at least one valve of the pneumatic spring assembly.

Claims (23)

1. A method for controlling a pneumatic spring assembly of a vehicle, comprising:

deriving discrete state parameters based upon a state of a vehicle;

combining the discrete state parameters into parameter sets;

allocating a defined height regulation behavior to each parameter set; and

electrically controlling a valve of the pneumatic spring assembly with an integrated control logic of the pneumatic spring assembly to set a specific height regulation behavior allocated to a specific state of the vehicle corresponding to a parameter set of the parameter sets, the integrated control logic deducing the specific state of the vehicle using electrical input signals.

2. The method as claimed in claim 1 , wherein one of the discrete state parameters is derived from a pressure value of the pneumatic spring assembly.

3. The method as claimed in claim 2 , wherein one of the discrete state parameters is derived from an operating mode of the vehicle.

4. The method as claimed in claim 1 , wherein the valve of the pneumatic spring assembly is an electronically-controllable proportional valve.

5. The method as claimed in claim 4 , wherein the electronically-controllable proportional valve comprises an integrated pressure sensor.

6. The method as claimed in claim 1 , further comprising: providing a further valve which is actuated on unchecked inflow of air into a spring of the pneumatic spring assembly.

7. A method for controlling a pneumatic spring assembly of a vehicle, comprising:

deriving discrete state parameters based upon a state of a vehicle;

combining the discrete state parameters into parameter sets;

allocating a defined height regulation behavior to each parameter set;

controlling a valve of the pneumatic spring assembly such that a specific height regulation behavior, which has been allocated to a specific state of the vehicle corresponding to a parameter set of the parameter sets, is set.

8. The method as claimed in claim 7 , wherein the valve of the pneumatic spring assembly is an electronically-controllable proportional valve.

9. The method as claimed in claim 8 , wherein the electronically-controllable proportional valve comprises an integrated pressure sensor.

10. The method as claimed in claim 7 , wherein one of the discrete state parameters is derived from a pressure value of the pneumatic spring assembly.

11. The method as claimed in claim 7 , wherein one of the discrete state parameters is derived from an operating mode of the vehicle.

12. The method as claimed in claim 10 , wherein one of the discrete state parameters is derived from an operating mode of the vehicle.

13. The method as claimed in claim 7 , wherein one of the discrete state parameters is derived from a distance between a vehicle body and a vehicle running gear frame.

14. The method as claimed in claim 13 , wherein, by controlling the valve of the pneumatic spring assembly, a specific height of the vehicle body in relation to a track is set, whereby a behavior of primary springing of the vehicle is derived from a pressure value of the pneumatic spring assembly.

15. The method as claimed in claim 7 , further comprising: providing a further valve which is actuated on unchecked inflow of air into a spring of the pneumatic spring assembly.
