Description
Being used for power actuated vehicle provides electric brake system as ABS, ESP or similar functions based on electromechanical units and comprise the electronic control unit (ECU) with electronic controller, and this electronic controller is connected with the electronic vehicle bus system.Electromechanical units also comprises the receiving member that is used for hydraulic unit (HCU), and electro hydraulic valve and backwash pump.In addition, on this receiving member, can connect conduit under fluid pressure that is used for car side brake and the hydraulic pressure connecting tube that is used for master brake cylinder.
In this electric brake system, secondary fluid circuit usually and the primary hydraulic pressure loop isolate fully, this primary hydraulic pressure loop makes master brake cylinder be connected with car side brake in a conventional manner.This isolation cause handling labor or when reinstalling brake system difficulty, this be because secondary fluid circuit in air filled cavity can not easily remove by means of the bleeding device in primary hydraulic pressure loop.Air is mingled with, and more specifically, unnecessary compressibility is intolerable in principle in brake system.
In the vehicle manufacturing, often carry out annotating or vacuum filling behind the so-called line.More specifically, the hydraulic unit of motor vehicle braking system does not have hydraulic fluid ground promptly to be done and is being installed in the vehicle, so that carry out so-called vacuum filling at the assembling line end with the hydraulic fluid that provides.Air in first treatment step in the brake system is sucked out (vacuum stages), the brake fluid that for example is in excessive rolling in second step is injected into (filling stage), the fluid that in third step, excessively injects be sucked out (the levelling stage, Nivellierphase).The filling and the venting that mainly are positioned at the secondary fluid circuit between normally closed solenoid valve (outlet valve) and the pump inlet valve are difficult tasks.Need switch the valve or the backwash pump of brake system for this purpose in single venting stage and filling stage definitely and synchronously.
DE 38 06 840 C2 disclose a kind of method of hydraulic pressure unit of the slip control system that is used to annotate.In order to remove entrained air in the brake system, a kind of venting computing machine is disclosed, this venting computing machine is equipped with current supply unit, operating unit and display unit.This independent venting computing machine comprises the microprocessor with the special control program that is used for the air removal.In order to remove purpose for air and to activate slip control system, pull up the plug of the core of a cable the vehicle from the electronic controller of slip control system.Then electronic controller is separately connected on the venting computing machine.Can carry out the venting sequence thus, backwash pump and electro hydraulic valve activated in venting sequence process, remove entrained air in the secondary fluid circuit of hydraulic pressure unit so that use the bleeding device (more specifically, by means of the air bleed screw on the car side brake) of primary flow body loop.
EP 0 323 889 A1 disclose a kind of anti-skid brake system with non-slip operation pattern and bleed air operation pattern.In order to adopt the bleed air operation pattern, this system is as being connected with diagnostic circuit with the venting plug by diagnosis interface among DE 38 06 840 C2, so that obtain the relative trigger data.If on diagnosis interface, there is not correct connection, then begin common non-slip operation circulation.This brake system also has and is used for forbidding enabling the device of bleed air operation pattern when the incoming signal of the wheel speed sensor on the electronic control unit (ECU) indication vehicle is in motion.
Therefore, the method for these motor vehicle braking systems that are used to annotate of the prior art is based on: for the venting pattern that realizes slip control system or add injection-molded and a bonded assembly process computer individually is provided respectively.In the venting pattern or add in the injection-molded, process computer activates the electronic controller of slip control system and pre-determines the pressure time that is used to control apparatus for filling distribute (Druckzeitverlauf).Between the electronic controller of process computer and brake system, need to provide respectively to be electrically connected.
The objective of the invention is to, make it possible to better, more cosily and more simply carry out filling processing and venting processing.The another one purpose is, reaches higher reliability when carrying out described processing.
This purpose realizes basically like this: during filling or venting processing, discern from the distribution of outside applied pressure time (filling trend, F ü llprofil) by means of vehicle-mounted sensing device; And, activate the electric liquid parts of brake system when needed by electronic controller corresponding to the filling trend of being discerned.Therefore, the present invention is mainly based on the following fact: vehicle-mounted sensing device has additional function in the venting or the cycle period of annotating; And the analyzed processing in the electronic controller of brake system of signal that is obtained and data activates being used for.Can still need not to give process computer with the handle data communication that is obtained forcibly.
For the actuating that meets demand, especially use the pressure threshold of determined filling trend.The present invention allows independently to exit and need not to activate slip control system by independent process computer, and this is to be preset to " vehicle-borne " to a certain extent because be used for the program code of actuated electro-hydraulic parts.In addition, because the car-mounted device of pressure sensor systems itself is used for the detected pressures threshold value, so the deflated state of brake system to a certain extent can determining by the scene.This allows to realize better quality assurance with supermatic subsequent treatment as early as possible when the venting processing is carried out.
The method according to this invention is brought such advantage: the process computer of filling and bleeding device separates with brake system in principle.In addition advantageously, between vehicle or control unit (ECU) and process computer (filling operatorless device), needn't there be cable connection.And current, decide on motor vehicle manufacturers, partly need for this purpose to have the more branch that separates on the cable harness of vehicle.Therefore can save these branches.
Even in order can to change the brake assembly of damage simply under the situation of non-processor computing machine, provide the brake assembly of so-called pre-filling up to now, these brake assemblys do not need to be exitted in the secondary loop yet.Different therewith, the not brake assembly of filling only is provided in the future, wherein, standing ground is carried by vehicle-mounted according to the present invention to be used to make the venting of electro-hydraulic brake device assembly and the necessary hardware and software of annotating.Authorized vehicle mechanical device is had make to do the brake assembly venting that state provides and the simple possibility of filling fully.Therefore overcome the mandatory reason of pre-filling brake assembly in the factory of brake manufacturer.This has eliminated the common demand of process computer and communication failure between process computer and electronic controller and the cable connection that is disturbed.
Second solution according to the problem of discussing, the vehicle-mounted venting method that is used for electric liquid assembly is set for anti-skidding control brake system, wherein, complete successfully and/or the information of unsuccessful interruption with filling and the relevant data of venting and the information such as the formal filling state of assembly especially with about the venting rules of assembly, under need not to visit the situation of external diagnosis device or control unit, be stored in the memory device of controller.Can realize durable venting rules thus, these venting rules also can cosily be carried out.This is to be set at the memory device of the controller of hydraulic pressure assembly because be used for carrying out data, code and the rules of venting rules, and is provided with assembly to a certain extent.Do not need diagnostic link with the external control unit.Owing to do not need diagnostic device, locate and work complexity in the workshop and cost reduction in the vehicle manufacturer.This makes the workshop that diagnostic device is not set also can carry out the venting rules.Improved the acceptability of electro-hydraulic brake system thus.
Another configuration according to second solution proposes, and the memory device of controller has and is used to the program code of rules of exitting, and the rules that are selected into that complete successfully are the conditions that are used to carry out the venting rules.Therefore program code is the pith of assembly, and the beginning of venting rules is carried out according to predetermined pattern.
In addition advantageously, be used for carrying out the memory device that the program code that is selected into rules is stored in controller, and be selected into rules and guarantee by means of the pre-code of determining.Avoided true and maintenance thus by the abuse of undelegated personnel component.
The method that is used to carry out the practicality that is selected into rules proposes, the described pre-code storage of determining is in the memory device of controller, and be selected into rules and comprise the identification of being undertaken by input code, conformability or difference between the code of the definite input of its middle controller and the code of storage, thus the venting rules only allow to enable when code is consistent.Code can be by means of the pre-operation mode of determining as especially number of operations, operating frequency or operating speed by man machine interface's input of power actuated vehicle.This relates to for example sin qua non's man machine interface, and as button, switch, handle or the sensor in particular for the actuated vehicle parts, they also have except having main actuation function and are used for the difunctional of input code.Can consider to be connected into whole man machine interfaces of power actuated vehicle in principle.Yet under the situation of considering practical balance, this relates in particular to conv and handle position, ignition device, glass regulator, flicker signal and the allied equipment of pedal and change-speed box.Can carry out numbers and symbols compiles and edit.In addition, can consider additionally or individually to use the hardware of determining to compile and edit by means of special (workshop) secret key, special chip card or allied equipment.
Following improvement measure is used for identifying purpose: be selected into the distribution of rules and/or the result preferably is stored in controller with the built-in system time memory device.In addition meaningfully, when success or the unsuccessful treatment step of finishing are recorded, about the distribution of venting rules and/or result's data storage in the memory device of controller.For example can identify that by these measures abuse is true.
Usually propose, the venting rules are broken down into a plurality of step S1-Sn in succession of front and back in time, provide definite state of the system (B in order to carry out each step S1-Sn, S, P, F, D, ID), each step (S1-Sn) has each one mutual level (I) and each one activity level (A) that is used to carry out inter-process in particular for selecting of being subjected to that the operator controls, quantitative data input or other action.In the case, the venting rules are made difference between following state of the system: B=activity (having much to do), and S=stops, and P=suspends, the F=fault, D=finishes (end), the ID=free time.State of the system (B, S, P, F, D ID) is recorded in the memory device.
Workman's (operator) main task is to monitor processing and be required to make each mutual level (I) all by means of confirming (instruction: continuation) be identified, so that automatically be transformed into activity level (A) after confirming.If the operator does not confirm that the rules of then exitting can be transformed among the state of the system S (stopping) that stops by interrupting (order: end) in mutual level (I) during each step.Thus, although the processing automation of height, the operator still obtains the control fully about handling.
Be provided with monitor for the venting rules.This monitor is guaranteed: the automatic supervision rules that are used for monitoring failure during the venting rules are activated; And under failure condition, automatically be transformed into state of the system F (fault).According to the fault order of severity, interrelate with turning back to last mutual level (I), the interruption of step (S) of the only current execution of the interruption fully (terminations) of whole venting rules or the rules of exitting is proposed.Each interruption all must be proved.
In addition, the present invention proposes a kind of device that is used to carry out according to the method according to this invention of second solution, wherein, the reservoir designs of controller becomes EEPROM.
When the rules that proposed can not be used for some reason, the present invention proposed, and controling appliance is useful on the interface of external diagnosis unit, and preset be selected into rules and can forbid enabling by means of this external diagnosis unit.Also considered to use the hope of traditional prior art thus.
Describe the present invention in detail below with reference to two scheme drawings that method of the present invention is shown on principle.
The suppliers of brake system make electric brake system with allow electronic controller independently annotate sequence treatment step and finish.
Fig. 1 represents a diagram of curves, the distribution of pressure of measuring by means of the pressure sensor of tandem main cylinder (P_Thz) be illustrated in filling as the function of time (processing time) in this diagram of curves during.According to pressure threshold 1 to 3, the control unit of drg is called in common filling sequence.
When implementing the method according to this invention, the sequence preference that describes below is implemented individually or in combination with one another.
For the dried brake system of annotating, for example ignition lock activated, and brake system is supplied with electric current.Then filling processing AFS (autonomous filling sequence) is activated, that is, in " igniting " afterwards, the electronic controller of brake system is waited for the beginning of predetermined pressure time distribution (filling trend) at least.This first sequence is also referred to as cognitive phase.Brake system in principle can not place in operation soon or in the filling treating process before filling is handled, that is, the function software of brake system is under an embargo (software is forbidden), this be because brake system by filling with hydraulic fluid.The distribution accurately of filling sequence is as follows:
-cognitive phase especially passes through the special state of the warning light of brake system, for example indicates as the flash of light of yellow or red braking warning light by warning light.The workman can identify thus, although brake system is activated, also is not in condition of readiness.
-after cognitive phase was finished on one's own initiative, this preferably was identified by corresponding show (for example flash rate of Jia Suing), and then is so-called vacuum stages, and brake system is sucked into vacuum in the process of this vacuum stages.
-at the corresponding pressure threshold of identification (because pressure threshold that the bar pressure of corresponding reduction does not reach in brake system) afterwards, the filling sequence (filling stage) that beginning is actual.In the process in this filling stage, the electronic controller of brake system start switching sequence (usually outlet valve and electric change-over valve and alternatively backwash pump be switched), and pressure fluid preferably is pressed in this system under pressure.
-being provided with the 3rd threshold value in addition, the 3rd threshold value is along with corresponding system pressure occurs, and is arranged on the back of first pressure threshold and second pressure threshold.After reaching the 3rd threshold value, introduce a levelling stage, in this levelling stage, the pressure fluid in the brake system and therefore Fluid Volume settle out.If brake system comprises too much hydraulic fluid, then this too much hydraulic fluid is removed from fluid container.
-when described three phases completed successfully, this fact Example was as extinguishing and confirmed by the workman by the braking warning light, and aforesaid operations software forbid cancellation.Power actuated vehicle can carry out ABS control or also can carry out in check test cycle in " testing behind the line " now.
If for example owing to vacuum leak is subjected to negative influence, then electronic controller distributes by means of pressure time and detects this fact the filling sequence for any reason.The preferred proposition, the electronic controller of brake system is suitably reacted to this interference.Suitable reaction for example is: the time length of current generation is prolonged simply, and perhaps controller is switched in the failure mode of the subsequent treatment with automatic or manual.This can give the workman by means of code (breakdown signal) indication of determining, and the brake system that has a fault can manually be deflated in the manually operated subsequent treatment in case of necessity.Failure mode for example can be by the warning light indication of special flash of light.Under failure condition, especially can propose, temporarily or constantly forbid the function software of electronic controller.Can discern this assembly at production line end (in the test of online back (EOL)).Cancelling this after fault is eliminated forbids.
Be higher or lower than definite pressure time threshold value and allow to interrupt the filling processing, and be transformed into failure mode.
Self-evident, can carry out the method according to this invention by means of pressure detection threshold value more than three.
Describe the processing of Fig. 2 below in detail.For the system of the different configurations that can comprise difference in functionality (ABS only being arranged, ABS and traction control (ASR), perhaps ABS and ESP function), it is identical that the basic structure of venting rules designs ground in principle.The essential characteristic of these venting rules is to be selected into and to select scheme or termination scheme, and described scheme is durable especially with respect to faulty operation or the casual action of operator.This is because the each system input of data or the confirmation that all needs the property confirmed of action at every turn.
To a certain extent, integrated communication offers the operator by the output unit (telltale, lamp, loudspeaker etc.) that is provided in advance with integrated menu control or the workman uses, so that exit rules.For example, the workman must confirm input, and the code that the motor vehicle braking system utilization is determined is confirmed the correct reception of this input by means of above-mentioned output unit.Can cancel thus and being connected of independent control or diagnosis unit.
The venting rules by a plurality of step S1 ..., Sn sequence form.In each step, there are each one mutual level I (state of the system w=waits, and is used to be selected into or select) and each activity level A (state of the system B=is busy).
In mutual level I, operator/workman by means of menu system by corresponding information automatically impel with move definitely, input etc., for example open the air bleed screw of determining on the wheel brake caliper.The carrying out of this action or input confirmed by means of order (for example " be selected into, continue ") by the workman.
The cooresponding activity level A of step S be proved or successful execution after, automatically be transferred to next step S with its corresponding mutual level I.After through n step, will automatically carry out the transition to state of the system " D " (finishing).
In each mutual level I, there is the possibility of interrupting (for example with order " termination ") whole venting rules.In the case, flow process control is branched off into lasting state of the system " S " (stopping).Handle to a certain extent and suspend.State of the system " S " can realize between each active stage that in principle its mode is for example to cause the corresponding input of drawing-in system state " S " by pressing button.It is to be branched off into state of the system " P " (time-out) that flow process is controlled in.State of the system " P " is similar with mutual level, that is, further order of implementing (" continuation ") and the interruptive command of determining (" termination ") are available.The mutual level I of the step S of nearest execution is led in order " continuation ", and " termination " causes current venting rules to stop and allowing restarting.
Also be provided with monitor in controller, this monitor monitors the venting rules automatically.Monitor also monitors: the condition that is used for the venting rules of success, as enough voltage rates (under-voltage supervision), vehicle parking state, tolerable ambient temperature and the hydraulic fluid temperature etc. of vehicle electrical systems, whether provide and during entire process, all exist.Monitor also can be used for making vehicle other parts for example drive context engine static and by rights (danger warning light operation is connected into horn for vehicle, or the combination of allied equipment and said apparatus for telltale, warning light) illustrate described static.
Also can consider the function except venting, can allow by the instruction of importing special coding to enable or forbid enabling definite function, for example RBT ASR or ESP function.Also can consider in this way, in the workshop of vehicle manufacturer, replenish the described function of equipment simply to brake system, perhaps the client for example uses the ESP function in time for winter months restrictedly, this ESP function after the time limit of permitting automatically or manually by deexcitation.
During being selected into rules or activity level A, the system failure or operator's mistake can detect by monitor.Fault cause for example may be the under-voltage of vehicle electrical systems, the setting of the fault position that is provided by supervision rules judicious, the opening of wrong air bleed screw on the wheel brake caliper, perhaps similar operation.Carry out the transition to state " F " (fault) thus.These faults are classified.Slight fault causes with good conditionsi returning (turning back to the mutual level I of current step S).On the other hand, serious or fatal fault causes unconditional returning, the automatic interruption of promptly whole venting rules.All (system) states are all communicated by letter to the workman by rights with effect.Failure message must confirm in principle in (for example, by instruction " continuation ").
Be recorded in subsequently in the memory device of controller by state of the system " S " (stopping), " F " (inefficacy), " D " (finishing) and this state, carry out the transition to state of the system " ID " (free time).Fault memorizer is preferably designed to EEPROM.
Along with beginning to enter the venting rules, in fault memorizer, set the internal state mark in succession.These marks comprise value and the storage of state and the unsuccessful interruption (fault memorizer) of venting rules of each step.
Can consider have in controller inside to make the operation of venting rules in principle, promptly essential processing, calculating and similar operations are carried out repeatedly independently of one another in controller inside redundantly.
For the interface of realizing the fail safe solution of tradition venting, also be provided with being used to controller is connected with the external diagnosis unit.This meets client's hope, even still allow to make assembly and brake system venting when described vehicle-mounted rules can not be used or should not use.
Understand easily, controller and right sensors system (temperature sensor, pressure sensor, stop lamp switch/brake operating sensor, or similar sensor is as (aging in particular for evaluating liquid hydraulic fluid quality, water constituent) sensor) is connected, must changes hydraulic fluid so that in time illustrate on the one hand to the vehicle driver.On the other hand, need this sensing system so that provide about in the brake system and the necessary information of the state of the system on the brake system for the Presentation Function of necessity and function for monitoring.
