Accompanying drawing explanation
Other features and advantages of the present invention are explained below by means of accompanying drawing.In the accompanying drawings:
Fig. 1 shows the schematic diagram of a kind of embodiment of brake system; And
Fig. 2 shows the diagram of circuit of the embodiment of the method for explaining the brake system for operational vehicle.
Detailed description of the invention
Fig. 1 shows the schematic diagram of a kind of embodiment of brake system.
Schematically graphic brake system can be used in vehicle/self-propelled vehicle in FIG, such as, can be used in battery-driven car or hybrid electric vehicle.It should be noted that, the workability of brake system is not restricted to certain vehicle type/self-propelled vehicle type.Although brake system described below can particularly advantageously be used in the vehicle with the distribution of X brake circuit, following described advantage also realizes in the vehicle distributed with parallel brake circuit.
Schematically graphic brake system comprises main brake cylinder 10 and braking liquid memory device 12 in FIG.Braking liquid memory device 12 can be understood as the volume of brake system, and in this volume, (usually) exists barometric pressure.Braking liquid memory device 12 such as can pass through at least one air extractor vent (Schn ü ffelbohrung) and be connected with main brake cylinder 10.Main brake cylinder 10 also (directly or indirectly) can connect brake operating element 14, such as brake pedal.The constructibility of brake system is not restricted to certain brake operating component type.
Brake system has two brake circuits 16 and 18 and four wheel brake cylinder 20 to 26.The arranging of brake system is connected on main brake cylinder 10 by least one first seperating vale 28 to the first wheel brake cylinder 20 of the first brake circuit 16.The arranging of brake system is also connected on main brake cylinder 10 by least one second seperating vale 30 to the second wheel brake cylinder 22 of the second brake circuit 18.In addition, arrange and be connected on braking liquid memory device 12 to first valve 32 of the first wheel brake cylinder 20 of the first brake circuit 16 by least one sustainable adjustment, and arranging is connected on braking liquid memory device 12 to second valve 34 of the second wheel brake cylinder 22 of the second brake circuit 18 by least one sustainable adjustment.In contrast to this, the arranging of brake system is connected on main brake cylinder 10 by least one first change-over valve 36 and the first high-voltage switch gear valve 38 to the 3rd wheel brake cylinder 24 of the first brake circuit 16.Correspondingly, arrange and be also connected on main brake cylinder 10 by least one second change-over valve 40 and the second high-voltage switch gear valve 42 to the 4th wheel brake cylinder 26 of the second brake circuit 18.
Advantageously, graphic brake system has the structure be parallel to each other of the first brake circuit 16 and the second brake circuit 18 in FIG.This makes brake system be simplified for the vehicle distributed with X brake circuit.For this reason, arrange and can be arranged on the common axle of vehicle to the second wheel brake cylinder 22 of the second brake circuit 18 to the first wheel brake cylinder 20 of the first brake circuit 16 and arranging.Preferably, the common axle of the first wheel brake cylinder 20 and the second wheel brake cylinder 22 is front axles of vehicle.Alternatively, the first wheel brake cylinder 20 and the second wheel brake cylinder 22 also can jointly be on the rear axle of vehicle.
By closing the first seperating vale 28 and/or closing the second seperating vale 30, arranging in the first wheel brake cylinder 20 of the first brake circuit 16 self and/or arrange in the second wheel brake cylinder 22 of the second brake circuit 18 self by reliably forbidding during driver's operation brake operating element 14 that braking liquid moves to from main brake cylinder 10.This situation also can be expressed as: can depart from from main brake cylinder 10 by closing the first seperating vale 28 and/or closedown the second seperating vale 30, first wheel brake cylinder 20 and/or the second wheel brake cylinder 22.Ensure with this, at least one brake-pressure be in the first wheel brake cylinder 20 and/or the second wheel brake cylinder 22 independently can be determined with the operation of at least one the main brake cylinder internal pressure in main brake cylinder 10 and/or brake operating element.Especially, can by least interim the opening (when the first seperating vale 28 keeps cutting out simultaneously) and/or reduce at least one brake-pressure being in the first wheel brake cylinder 20 and/or being in the second wheel brake cylinder 22 by least interim open (when the second seperating vale 30 keeps cutting out simultaneously) of the second valve 34 of sustainable adjustment of the first valve 32 of sustainable adjustment.At least one reduction property being in brake-pressure that is in the first wheel brake cylinder 20 and/or that be in the second wheel brake cylinder 22 may be used for the mechanism of power generation kinetic moment of blanking (Verblenden) (unshowned) electrical generator especially.Therefore brake system shown in Figure 1 can particularly advantageously be used in vehicle for regenerative brake.Especially, can be ensured by brake system, although use the electrical generator being used for regenerative brake at least provisionally, the chaufeur braking be no more than by operation brake operating element 14 is given in advance is wished.Therefore brake system improves the driver comfort of its user during regenerative brake and therefore facilitates sale that the is energy-conservation and vehicle of anti-emission carburetor.
Simultaneously, ensure that in brake system, user can be braked by least valve 36,38,40 and 42 by operation brake operating element 14 in the 3rd wheel brake cylinder 24 that arranges to the first brake circuit 16 and braking to arranging in the 4th wheel brake cylinder 26 of the second brake circuit 18.Therefore, even if chaufeur still has standard compliant brake operating sensation (pedal sense) after the first wheel brake cylinder 20 and/or the second wheel brake cylinder 22 depart from during operation brake operating element 14.Therefore do not need for brake system assembly simulation device (pedal simulator).As an alternative, the 3rd wheel brake cylinder 24 and the 4th wheel brake cylinder 26 meet braking function and " simulator function " simultaneously.By eliminating due to the multifunctionality of the 3rd wheel brake cylinder 24 and the 4th wheel brake cylinder 26, for the essentiality for brake system assembly simulation device, the weight of brake system can be reduced and save the space structure be equipped with on the vehicle of brake system.Additionally, the cost of simulator is eliminated when the brake system shown in shop drawings 1.
In the embodiment of figure 1, the first feed pipe 44 of brake system extends to the first seperating vale 28 from the first pressure chamber of main brake cylinder 10.First change-over valve 36 and the first high-voltage switch gear valve 38 are connected on the first branch point 46 of being in the first feed pipe 44 in parallel to each other.Such as, the intermediate duct 48 of branch can extend to the first change-over valve 36 and the first high-voltage switch gear valve 38 from the first branch point 46.Second feed pipe 50 of brake system is directed to the second seperating vale 30 from the second pressure chamber of main brake cylinder 10.Second change-over valve 40 and the second high-voltage switch gear valve 42 are connected on the second branch point 52 of being in the second feed pipe 50 in parallel to each other.The intermediate duct 54 of branch also can extend to the second change-over valve 40 from the second branch point 52 and extend to the second high-voltage switch gear valve 42.Therefore, reliably ensure that: both braking liquid will be hindered to move to the first change-over valve 36 or the first high-voltage switch gear valve 38 from main brake cylinder 10 by the closedown of the first seperating vale 28, also can not be stoped by the closedown of the second seperating vale 30 and hinder braking liquid to move to the second change-over valve 40 or the second high-voltage switch gear valve 42 from main brake cylinder 10.
Preferably, brake system also has the first aspiration 56 of the first valve 32 extending to sustainable adjustment from braking liquid memory device 12.In addition, brake system can have the first pump 58, and the suction side of described first pump 58 is connected on the 3rd branch point 60 that is in the first aspiration 56.Second aspiration 62 of brake system extends to the second valve 34 of sustainable adjustment from braking liquid memory device 12 also advantageously, and the suction side of the second pump 64 of brake system is connected on the 4th branch point 66 that is in the second aspiration 62.First pump 58 and/or the second pump 64 achieve the rising of at least one brake-pressure be in the first wheel brake cylinder 20 and/or the second wheel brake cylinder 22 in the case.Can such as mechanism of power generation kinetic moment that blanking reduces in time by operating that the first pump 58 and/or the second pump 64 can cause, in the first wheel brake cylinder 20 and/or the second wheel brake cylinder 22 brake-pressure raises.
Similarly, the brake-pressure that can cause raises and also may be used for braking force enhancing.To be braked to non-reinforcing by operation brake operating element 14 the 3rd wheel brake cylinder 24 at chaufeur and brake in the 4th wheel brake cylinder 26, (after the first seperating vale 28 and/or the second seperating vale 30 are closed) can set up at least one by the operation of the first pump 58 and/or the second pump 64 and be in the first wheel brake cylinder 20 and/or the brake-pressure be in the second wheel brake cylinder 22, and described brake-pressure is apparently higher than the build-up pressure caused in the 3rd wheel brake cylinder 24 and/or in the 4th wheel brake cylinder 26.Therefore do not need such as, for brake system assembling brake servo unit, vacuum brake assistor.As an alternative, the first pump 58 and/or the second pump 64 can meet by the function of the brake servo unit of simplifying completely.Especially, chaufeur only needs relatively low chaufeur braking force to be applied on brake operating element 14, raises although there is relatively large brake-pressure in the first wheel brake cylinder 20 and/or in the second wheel brake cylinder 22.
By simplifying brake servo unit in brake system, as particularly vacuum brake assistor, not only reducing the space structure demand of brake system, and reduce its weight and manufacturing cost.Especially, when the vehicle being equipped with brake system does not have combustion engine or when long period section does not use combustion engine, the brake system of brakeless servo-unit ensures that chaufeur also has comfortable brake operating sensation (pedal sense).Because brake system there is no need for the vacuum brake assistor ensureing good brake operating sensation, so also eliminate the essentiality of vacuum feed.In addition should point out, the favourable design of brake system achieves the vacuum pump of simplifying machinery, described vacuum pump usually on vehicle or often need and disadvantageously increase the discharge of vehicle.

In the embodiment of figure 1, four pumps 58,64,102 and 110 of brake system are connected on the common axle 116 of pump motor 118.Therefore do not need for brake system is equipped with multiple pump motor.Four pumps 58,64,102 and 110 are such as configured to single piston pump respectively.Therefore the brake system of Fig. 1 can be described as four piston ESP systems.But it should be noted, the constructibility of brake system is not restricted to certain pump type.For pump 58,64,108 and 110, at least one pump with different number of pistons, at least one non-symmetrical pump and/or at least one gear type pump therefore also can be used.
Such as, the brake system of Fig. 1 has the pre-pressure sensor 120 be connected on the first brake circuit 16 and the pressure sensor 122 be connected in the first wheel brake cylinder 20 and the second wheel brake cylinder 22.But the constructibility of brake system is not restricted to the certain structure with pre-pressure sensor 120 or pressure sensor 122.In order to detect the manipulation strength of chaufeur braking hope or driver's operation brake operating element 14, at least another brake operating element sensor 124 additionally can be used in brake system.At least one brake operating element sensor 124 can be such as pedal stroke sensor, progressive error sensor and/or throw of lever sensor.Also the sensing device by other types detects chaufeur braking hope.
At brake system run duration, specified lock torque can be determined by brake operating element sensor 124 according to the manipulation strength of operation brake operating element 14.In order to realize the specified lock torque desired by chaufeur, the first seperating vale 28 and/or the second seperating vale 30 can be closed, thus in the first wheel brake cylinder 20 and/or in the second wheel brake cylinder 22, set up brake-pressure by sustainable the causing of operation of the first pump 58 and/or the second pump 64, until specified lock torque given in advance by four wheel brake cylinder 20,22,24 and 26 as adding and being applied on relevant wheel.Because make braking liquid move in the 3rd wheel brake cylinder 24 and the 4th wheel brake cylinder 26, so described chaufeur also has standard compliant brake operating sensation (pedal sense) by operation brake operating element 14 during the process that chaufeur is described herein.Meanwhile, the brake-pressure set up in the first wheel brake cylinder 20 and/or the second wheel brake cylinder 22, apparently higher than the pressure caused in the 3rd wheel brake cylinder 24 and in the 4th wheel brake cylinder 26 by chaufeur braking force, can cause braking force to strengthen thus.
When brake off, chaufeur can make braking liquid volume from the 3rd wheel brake cylinder 24 and the 4th wheel brake cylinder 26 again movement turn back in main brake cylinder 10.Correspondingly, also brake-pressure can be caused to reduce in the first wheel brake cylinder 20 and/or the second wheel brake cylinder 22 by the second valve 30 of the first valve 28 of sustainable adjustment and/or sustainable adjustment.Therefore chaufeur can not be felt: except the braking liquid that directly caused by chaufeur braking force main brake cylinder 10, mobile between the 3rd wheel brake cylinder 24 and the 4th wheel brake cylinder 26 except, in brake system, also additionally carried out braking liquid moved.
In an emergency braking situation, such as burst brake condition under and when operating brake operating element 14 very soon at associated therewith, chaufeur, seperating vale 28 and 30 can stay open.Therefore, chaufeur also can move snap catch in the first wheel brake cylinder 20 and the second wheel brake cylinder 22 by the volume of main brake cylinder 10.Therefore quick delivered volume under not needing the first pump 58 and the second pump 64 to be arranged in use in emergency braking situation.As an alternative, the model (Modelle) of price cheapness can be used for pump 58 and 64.
Such as, can be checked by least one brake operating element sensor 124, whether the operation of brake operating element 14 demonstrates the instruction of emergency braking situation/burst braking.Especially, can check implement during operation brake operating element 14 depress gradient (Eintrittsgradient).At least one environmental sensor also can be considered for determining emergency braking situation.In the emergency braking situation determined/burst braking when, seperating vale 28 and 30 can be allowed to be in its state opened under.With this, brake system allows the utilization to driver dynamic characteristic the best when higher snap catch requires.Although there is limited pump dynamic characteristics due to the pump type of price cheapness, high braking dynamic characteristics also can be realized with this.After a certain time or when reaching lock torque given in advance, seperating vale 28 and 30 can be closed, thus further pressure can be caused to raise by the first pump 58 and the second pump 64.
ABS is regulated and can be undertaken by wheel outlet valve 78 and 84 by wheel access valve 76 and 82 routinely.For the axle of the first wheel brake cylinder 20 and the second wheel brake cylinder 22, ABS regulates also to be discharged in braking liquid memory device 12 by the valve 32 and 34 of sustainable adjustment and by braking liquid and realizes.Favourable ABS adjusting function (can compared with the brake system of routine) therefore also obtains in the brake system of Fig. 1.
In wheel brake cylinder 24 and 26, vehicle stabilization can be made by means of standard ESP control system by the brake intervention (Bremseneingriffe) of individual wheel.Stable interference (Stabilisierungseingriffe) in wheel brake cylinder 20 and 22 can when seperating vale 28 and 30 cuts out by the valve 32 and 34 of sustainable adjustment and pump 58 and 64(as in the brake system in routine) carry out.
Actv. pressure capacity-building can be realized by change-over valve 36 and 40 and high-voltage switch gear valve 38 and 42.The valve 32 and 34 of sustainable adjustment also may be used for (for two axles) tractive force slide control.The brake system of Fig. 1 be therefore suitable for nonfunctional shortcoming f-w-d, back-wheel drive with all-wheel powered vehicle.Because typical valve is arranged, also can realize as by driver's operation and effective by the part of the function of the auxiliary combination formed of regulon.Therefore all known part actv. functions can carry out on nonfunctional restriction ground.
Can be undertaken braking with regenerating by electrical generator, therefore (when seperating vale 28 and 30 cuts out) braking liquid can be discharged in braking liquid memory device 12 by the valve 32 and 34 of sustainable adjustment and to require the corresponding lock torque of electrical generator.During the braking of regeneration, chaufeur also has standard compliant brake operating and feels (pedal sense) due to contacting of itself and the 3rd wheel brake cylinder 24 and the 4th wheel brake cylinder 26.Because the obvious of wheel brake cylinder 20 and 22 crosses braking, there is relatively large reducible hydraulic braking moment for regenerative brake.Therefore ensure that high regeneration efficiency.
Preferably, valve 28,30,36,40,76 and/or 82 is the valves often opened.For valve 38,42,78 and/or 84, be preferably normally closed structure.Therefore in mechanical standby solution (R ü ckfallebene), (when valve not through-flow) still can in the braking to all wheel brake cylinder 20 to 26 of non-reinforcing ground for chaufeur, and realizes enough slowly minimum with this.
Therefore following advantage integrates by the brake system of Fig. 1: comfortable brake operating sensation (pedal sense), low manufacturing cost, light weight, low space structure demand, high safety and the applicability for the distribution of X brake circuit.In addition, brake system also can be configured to compact parts.
Fig. 2 shows the diagram of circuit of a kind of embodiment of the method for explaining the brake system for operational vehicle.
The method further described can such as be performed by aforementioned brake system.But the enforceability of described method is not restricted to this brake system type just.

With method step S1 side by side manner of execution step S2.In method step S2, control first change-over valve like this and the first high-voltage switch gear valve and the second change-over valve and the second high-voltage switch gear valve, the braking liquid volume extruded from main brake cylinder by operation brake operating element is moved in the 3rd wheel brake cylinder at least in part with in the 4th wheel brake cylinder, wherein, the arranging of brake system is made to be connected on main brake cylinder to the 3rd wheel brake cylinder of the first brake circuit by described first change-over valve and the first high-voltage switch gear valve, and by described second change-over valve and the second high-voltage switch gear valve, the arranging of brake system is connected on main brake cylinder to the 4th wheel brake cylinder of the second brake circuit.Therefore, although (being caused by method step S1) the first wheel brake cylinder and the second wheel brake cylinder are departed from from main brake cylinder, chaufeur still has standard compliant brake operating sensation (pedal sense) during operation brake operating element.Especially, therefore chaufeur can not be awared with main brake cylinder internal pressure and operate brake operating element and be independently in the first wheel brake cylinder at least one and/or be in the adjustment that the brake-pressure in the second wheel brake cylinder carries out.Such as, in the method step S3 performed during method step S1 and S2, the brake-pressure in the first wheel brake cylinder and/or the second wheel brake cylinder can be reduced during operation brake operating element.This can by opening the first valve of sustainable adjustment and/or being realized by the second valve opening sustainable adjustment at least provisionally at least provisionally, wherein, by described first valve, the first wheel brake cylinder is connected to (and the first seperating vale keeps cutting out) on the braking liquid memory device of brake system, and by described second valve, the second wheel brake cylinder is connected to (and the second seperating vale keeps cutting out) on braking liquid memory device.By reducing the brake-pressure in the first wheel brake cylinder and/or the second wheel brake cylinder, the mechanism of power generation kinetic moment increased in time of electrical generator can such as by blanking for carrying out regenerative brake to the vehicle being equipped with brake system.
As method step S3 substitute or supplement, also can during method step S1 and S2 manner of execution step S4.In method step S4, during operation brake operating element, improve the brake-pressure in the first wheel brake cylinder and/or the second wheel brake cylinder.This is by making the first pump operation of brake system and/or making the second pump operation of brake system occur, wherein, the suction side of described first pump is connected to (and the first seperating vale keeps cutting out) on braking liquid memory device, and the suction side of described second pump is connected to (and the second seperating vale keeps cutting out) on braking liquid memory device.By improving the brake-pressure in the first wheel brake cylinder and/or the second wheel brake cylinder, can the mechanism of power generation kinetic moment reduced in time of such as blanking electrical generator.In addition, method step S4 also may be used for braking force enhancing.In the 3rd wheel brake cylinder, also brake period in the 4th wheel brake cylinder in the braking of chaufeur (due to method step S2) non-reinforcing ground, in the first wheel brake cylinder and/or the second wheel brake cylinder, set up the brake-pressure of obviously increase in the case by method step S4.By method step S4, therefore can realize braking force and strengthen in the brake system of brakeless servo-unit.
Can also manner of execution step S0 before method step S1 and S2 in a selectable manner.Can determine in method step S0 whether (during driver's operation brake operating element) exists emergency braking situation.Emergency braking situation is there is, then under the first seperating vale and the second seperating vale can being adjusted to its state opened in method step S5 if determined.Therefore the fast speed braking dynamic characteristics of the chaufeur in emergency braking situation also to may be used in the first wheel brake cylinder and set up brake-pressure in the second wheel brake cylinder.This means only determine there is not emergency braking situation time, during operation brake operating element, forbid that braking liquid moves in the first wheel brake cylinder from main brake cylinder and in the second wheel brake cylinder by method step S1.
