(Aktoren) and there are also the controllers including security monitoring), so these systems come client or terminal client
It says more expensive.
Summary of the invention
Therefore task of the invention is, in the parking braking system of automation, the degree of automation is reduced, to design
Low-cost total system.
The task is addressed by following characteristics: during each parking braking, activating the parking braking

Come, the pressure of service braking system is just locked.
For this purpose, describing a kind of in the motor vehicle with hydraulic running brake and the parking brake of automation
The middle method for implementing parking braking process.Provide according to the present invention, during each parking braking at least partially through
Vehicular occupant generates the brake force established after activating the parking braking process.
Parking braking process is understood to each process for allowing vehicle parking (feststellt).It is especially appreciated that herein
For the docking process of vehicle, wherein driver leaves vehicle after the docking process, especially within the longer duration
?.In addition, parking braking process also can refer to can to allow the of short duration park (Halten) of vehicle process, for example at slope (Berg)
On park process.Driver, which generally remains, during park is sitting in vehicle.
Need the brake force established can with the park power (Haltekraft) and brake piston and brake disc of vehicle it
Between clamping force it is mutually equivalent, or be converted into these power.The generation of brake force herein should be at least partly by Vehicular occupant, outstanding
It is realized by driver.
According to the present invention, brake force is during each parking braking and thus in the parking braking process of beginning
Middle generation.Herein It is not necessary to meet other conditions, such as derive that from these conditions, single force component (such as passes through
The force component that actuator generates) not enough, and therefore need another force component (such as the force component generated by driver).
This kind of condition may be the stop high gradient of plane and/or the high-temperature of brake.
The method provides in a kind of further deep design scheme, even if in back to back cinching process again
(Nachspannvorgang) also implement the generation of brake force in by Vehicular occupant.
When identifying parking braking requirement, parking braking process is activated.Parking braking is required to as driver
Parking braking be expected that by the manipulation of operating element realized by driver.This to for example be mentioned to known in a manner of it
Parking braking key manually handle.Operating element can be optionally provided in driver's cabin.The operating element is advantageously
It is the operating element different from the brake pedal of running brake.The key can be used in requiring locking parking brake herein
(" lock(latching) "), unlock the same (" release(release) ") and be also provided with emergency deceleration.When driver compared with
In the case where high speed (such as in the case where being greater than 3km/h) when activating brake key, just implement emergency deceleration.Due to
Speed is higher, so parking braking process is impossible.But when key is by Constant manipulation, vehicle is just decelerated.Once
The speed of vehicle is decreased, and (such as to 3km/h or less), and then parking braking process can start if necessary.When other
Specific condition show presently, there are the parking braking of driver it is expected or the short time in formed parking braking expectation when, also can
Enough identify that parking braking it is expected.
Other than the parking braking of driver expectation, also it can be considered that the automation of parking brake force requires.As can
The example of the requirement of energy, it should be mentioned that so-called slope keeps function (Hill-hold-Funktion), and wherein vehicle briefly exists
When being maintained on slope at existing position, such as encountering traffic lights parking on the slope.Acceleration transducer can be set thus.
This sensor can detect the gradient of park situation in the stationary state of vehicle by the gradient of vehicle.
It provides according to the present invention, Vehicular occupant works together when generating and needing the brake force established, which exists
It is established after activating brake process.This is understood to, realizes the activation of parking braking process first, and immediately really
Existing brake force generates, and when brake force generates, such as driver generates at least part for the power for needing to be established.Certainly, it drives
Member just can be already engaged in or implement before activation the generation of brake force.
It especially provides, driver generates brake force by means of hydraulic running brake.It advantageously provides for, in activation parking
The brake force needed after braking process is established by means of running brake completely.Pass through driving system by hydraulic brake pressure
And then the brake force that dynamic device generates can be passed in the electromechanical parking brake of automation, or be transferred to parking
Brake is received by the parking brake.
The parking brake of automation is for example configured to " motor on caliper " (clamp integrated form motor) system, and
And it is combined with running brake, or be integrated into the system of running brake.Parking brake can have self-locking
Main shaft driving device, wherein the brake piston of running brake by guidance (nachgef ü hrt) main shaft back side support,
That is it is fixed in the position deviated by hydraulic pressure.Thus, it is possible to be advantageously carried out closing to the brake piston of offset
Lock.It is maintained by means of the parking brake that the brake force that running brake is established then passes through automation, without continuous
Ground maintains corresponding power by driver or actuator.Advantageously --- especially in reduced size and it is associated with it
Cost decline aspect --- can provide, mainly realized only by the actuator for actuating parking brake locking and not
Realize that power is established.
In order to unclamp parking brake, electromechanical regulating mechanism is steered towards opposite direction, and the regulating mechanism is thus
Parking braking blocking mechanism is discharged again.The parking braking blocking mechanism correspondingly so constructs, so that even if the torque of very little
Also it is enough to unclamp.Pressure auxiliary for release function in case of need equally also can be by driver or hydraulic
Actuator provides.Then, known function AVR(Automated Vehicle Release can additionally be dominated: automatic
Vehicle is let pass).Driver can for example start from dead ship condition in the case where no rollback on the slope.
Based on described method, can unchanged be generated designed for the pressure of hydraulic running brake existing
Component, because only there is the smallest extra load.In addition, automation parking brake component can power it is lower and
Thus also can smaller and cost design lower.Example as this kind of design scheme simplified is refering to (verwiesen)
The motor gearbox unit of parking brake, because the actuator does not resettle power, but only that the end of locking brake piston
Position.
It is provided in a kind of advantageous design scheme, by Vehicular occupant by means of the behaviour of the brake pedal to running brake
It indulges to start the foundation of brake force.
This is understood to, starts to brake by trampling the brake pedal of hydraulic running brake by such as driver

Such as it can be put into practice by red or/and yellow functional lamp/warning light.
Provided in another advantageous design scheme, to Vehicular occupant export size in relation to current brake force with/
Or need the information of the size for the brake force established.
The request for being previously described for establishing brake force defines digitized expression (" needing to establish brake force ", " no
Need to establish brake force "), and driver obtains further information in this sense.Work as example, this category information can embody
Preceding brake force or the at present brake pressure present in braking system.Can additionally export in relation to required brake force or
Person is in relation to there is the information of brake pressure to be achieved.This category information can be given in the form of absolute physical parameter.
Advantageously however, only output represents the parameter of this physical parameter in the sense that customer-orientation, such as
In the form of " brake pressure is low and brake pressure is high " or in the form of " brake pressure deficiency and brake pressure are sufficient ".Herein
It also can be by realizing expression from a kind of feature (Auspr gung) to the continuously item of another feature.As substitution
Scheme is also able to use for example using triphasic (dreistufig) scale as the section stage of form
(Intervallstufen).The section stage, which especially seems, to be suitable for realizing simple understanding in terms of user.Here,
Group is merged to use and be seemed by (green, yellow, red) the coloured mark in the form of of triphasic traffic lamp switch (Ampelschaltung)
Favorably.It can intuitively and with being readily appreciated that be linked up with client whereby: be that there is sufficient brake pressure (green lights in system
Stage) or there is no sufficient brake pressures (red light phase) or brake pressure to be currently in possible unfavorable transitional region
(amber light stage).Certainly, information output will correspondingly adapt to current required braking force.Such as it is smaller in the gradient of parking plane
When need lesser brake pressure.Therefore, green is just correspondingly had shown that in the case where the brake pressure of lesser foundation
Traffic lamp switch.Additionally it is possible to shown by the information of variation and/or to the request of driver come it is practicable have it is to be achieved
The different size of brake pressure.
It provides in a kind of design scheme of substitution, in the hypodynamic situation of braking of foundation, is exported to Vehicular occupant

It similar to the previously described design scheme of the method, can advantageously provide for, brake present in the system
When power is not enough to parked vehicle as required, driver obtains directly information related with safety.In this way
The driver of design scheme, vehicle obtains the direct feedback in relation to successfully meeting required braking force.Similarly, in this way can
Enough avoid, although already existing brake pressure is sufficiently high, also exported to driver --- do not have on that point
It is necessary --- request.By avoiding unnecessary information and selection and transmitting important information to driver, alleviates and drive
The burden for the person of sailing, and driver is allowed to be absorbed in important information.The output of this information equally can be for example with optical, sound
Form learn or tactile is realized.
It is natural it is contemplated that this information exported in the previously described manner equally can include or represent for establishing
The request of brake force.Furthermore also it is possible that according to the required size of brake force or the braking pressure controlled by driver
The required size of power exports the letter of change by the required size of the variation of the brake pressure of driver control
Breath and request, to transmit specific information respectively for current application scenarios.
It provides in the advantageous design scheme of another kind of the method, is mainly opened when activating the parking braking process
It is dynamic that the parking brake is actuated.
On the basis of activating brake process, can simultaneously or it is significantly postpone in the case where realize and stay
The activation of the brake actuator of vehicle brake.Manipulation to actuator is it is achieved that when manipulating hydraulic running brake pair
The lasting guidance (Nachf ü hrung) of parking brake.Thus, it is possible to advantageously directly, namely in the not significant time
In the case where delay, the brake force generated by running brake is passed to the parking brake of automation.Thus, it is possible to realities
Now to the instant maintenance of the brake force of foundation." actuating (Aktuierung) " this concept is understood as activating within a context.
In addition, corresponding manipulation equally will also appreciate that actuate.Advantageously, providing herein, pass through driving system in brake apparatus
When dynamic device progress power is established, the actuator of parking brake is guided.Here, this manipulation also can include one kind certainly
For the method for manipulation, to avoid the overload of actuator when necessary, such as by current value and voltage value to actuator or
