Braking system usually have generate compressed air piston compressor.Here, piston compressor is usually or by the special of oneself
It is driven with driving device or is for example driven by the identical motor of driving vehicle.Due to being activated sometimes for high volume flow
Brake apparatus, and compressor is not necessarily capable of providing these volume flows, so compressor will not be used directly to triggering braking
Device, but for filling compressed air storage device, for example by electrically or pneumatically manipulating after the compressed air storage device
The opening of valve drives brake.Thus, for example after braking process or activating other be coupled in compressed air system
Pressure air consumer after or in the case where compressed air is flowed out due to leakage, to compressed air storage device
Filling is especially necessary.
It is general in the prior art, in order to fill compressed air storage device, piston pump is in no transmission ratio
In the case of for example by the internal combustion engine drives of vehicle.Especially, piston pump has revolving speed identical with internal combustion engine.So
And because the abrasion of piston pump is related with the cumulative duration that it is manipulated, in other words because its service life is manipulated with it and held
The continuous time is inversely proportional, it is desirable that only application piston pumps on the period as short as possible.
Summary of the invention
The task of the present invention is realize a kind of compressed air system, in the compressed air system, piston pump is as low as possible
It abrasively be used to fill compressed air storage device.
The task is solved from feature according to the present invention.The application documents of the application illustrate advantageous extension structure of the invention
Type simultaneously introduces method according to the present invention.

The temperature of piston pump and/or the lubricating oil of driving device or the air themperature being designed to inside compressed air storage device.
Monitor vehicle ambient temperature, especially by piston pump aspirate air temperature the advantages of also reside in, example
Such as (in the case where the zubzero temperature therefore the desiccant of compressed air system may freeze and in the case where zubzero temperature
Do not work), to make the revolving speed of compressor draw volume stream reduces in other words, flows through during aspiration procedure so as to heat
Air.The advantages of monitoring such as lubricating oil temperature used in driving device or piston pump or coolant temperature, is, is moistening
The revolving speed of piston compressor can be correspondingly reduced in the case where lubricating oil or coolant liquid exceedingly heating.Therefore, it can especially avoid
The damage of piston compressor or driving device due to caused by overheat.
Monitor compressed air storage device inside air themperature the advantages of in particular, in that, by knowing as thermodynamics shape
The temperature of state parameter is and at the same time know the pressure being contained therein, such as can be inferred that the particle of air wherein included
Measure quality in other words.The such as less than predetermined threshold value of the air quality can then be used as that the triggering of piston pump is activated to sentence
According to.
According to the preferred embodiment of the present invention, at least one described sensor design is at pressure sensor, it is described at least
One vehicle parameter is designed to the tire pressure of at least one wheel of vehicle or is designed to inside compressed air storage device
Air pressure or air quality or air capacity are designed to the air stream leaked out from compressed air system due to leakage.
The advantages of examining tire pressure especially obtains in these vehicles: in these vehicles, tire can pass through compression
Air system is for example also inflated during the driving period.Here, the decline of tire pressure can be required to compressed air storage device
It is filled, that is, activates or accelerate piston pump.
Examine the air pressure in compressed air storage device in other words air quality examine in other words due to leakage and from
The volume flow leaked out in compressed air system equally can be used for the speed activation of piston pump in other words for triggering piston pump
Criterion.
Measure of the invention is improved according to one, at least one described sensor monitors at least one of compressed air system
The activity of pressure air consumer, such as parking brake or Aeroassisted system.By monitoring compressed air consumption dress
Set the raising that can trigger the piston compressor revolving speed thus needed.
Other vehicle parameters as the revolving speed for changing driving device are it is also contemplated that such as firing key position, i.e.
Position of the firing key in ignition switch.Thus derive such information: vehicle is to prepare operation or go back in operation
It is that the two is all non-.In addition, in this respect it is also contemplated that the real-time accelerator pedal position and/or fired state of vehicle, this can be with
It is determined by using sensor technology or signal processing technology.
It for example can also be incited somebody to action when reaching the maximum pressure of the restriction in compressed air system by solution of the invention
The revolving speed of driving device changes to zero.In this regard piston pump can be also completely switched off after filling compressed air.Class
As, the measure in the control technology can be also used when reaching other critical vehicle parameters.
Measure of the invention is improved according to one, the driving device of piston pump is configured to internal combustion engine or motor or liquid
Pressure motor or at least one wheel for being configured to vehicle.It is therein the advantage is that by it is already existing, in terms of its revolving speed energy
The system being steered is used as driving device.
Measure of the invention is improved according to one, piston pump is connected on auxiliary actuator.This can be realized and driver
The coupling using parallel piston pump real, script, meeting purpose.Such auxiliary actuator can for example construct
At the axis stretched out from actuator housing.By the measure, piston pump also can be when transmission for vehicles be separated with drive motor
It is driven.
According to the preferred embodiment of the present invention, control request is designed to shift request and/or revolving speed to driving device
Change request.Here, advantage in particular, in that, such as can pass through during the driving period while improve the revolving speed and simultaneously of driving device
The gear being linked into is reduced in other words as caused by speed changer, transmission ratio of the rotational speed of driving unit relative to vehicle wheel rotational speed, it can be real
It is existing, it can be realized the raising of piston revolution speed in the case where car speed remains unchanged.
The inventive process provides the measurement for supplying relevant parameter to compressed air and the revolving speed for making piston pump and it is somebody's turn to do
The subsequent adaptation of parameter.
Detailed description of the invention
It is shown specifically referring to unique attached drawing and improves other measures and the preferred embodiment of the present invention of the invention.Attached drawing
The diagram of compressed air system of the present invention is illustrated as box.
