Description of drawings
Next according to the hydraulic circuit diagram shown in the accompanying drawings the present invention is set forth in detail, this underground illustrates the hydraulic vehicle brake system that is used for implementation basis method of the present invention.
The specific embodiment
Hydraulic vehicle brake system 1 illustrated in the accompanying drawings has anti-skidding control setup (slip controller ABS; Drive anti-skidding control setup ASR; Vehicle dynamics control setup FDR, ESP).Said hydraulic vehicle brake system is constructed to have the split brake system of two brake circuit I, II, and these two brake circuits are connected with main brake cylinder 2.Each brake circuit I, II are connected with main brake cylinder 2 through a disconnecting valve 3.These disconnecting valves 3 are two-position two-way solenoid valves of opening at the initial position of its outage.Hydraulically parallelly connected respectively ability is from main brake cylinder 2 through-flow boiler check valve 6 to car side brake 4,5 on each disconnecting valve 3.The disconnecting valve 3 of each brake circuit I, II is connected with car side brake 4,5 via brake-pressure pressure charging valve 7.Brake-pressure pressure charging valve 7 is two-position two-way solenoid valves of opening at the initial position of its outage.These pressure charging valves are parallelly connected with boiler check valve 8, and these boiler check valve can be through-flow towards the direction of main brake cylinder 2 from car side brake 4,5.
On each car side brake 4,5, be connected with a brake-pressure reducer 9, these brake-pressure reducers are connected on the suction side of Hydraulic Pump 10 jointly.Braking reducing valve 9 is constructed to the two-position two-way solenoid valve of closing at the initial position of its outage.On the pressure side being connected between brake-pressure pressure charging valve 7 and the disconnecting valve 3 of Hydraulic Pump 10, that is, on the pressure side being connected with car side brake 4,5 through brake-pressure pressure charging valve 7 and passing through disconnecting valve 3 of Hydraulic Pump 10 is connected with main brake cylinder 2.Each car side brake 4,5 has pressure sensor 11.
Among two brake circuit I, the II each all has a Hydraulic Pump 10, and these two Hydraulic Pumps can drive through an electrical motor 12 jointly.The suction side of Hydraulic Pump 10 is connected with brake-pressure reducer 9.Be provided with the hydraulic accumulator 13 that is used to hold with the relay storage braking liquid in the suction side of Hydraulic Pump 9, this braking liquid flows out from car side brake 4,5 through open brake-pressure reducer 9 at the vehicle wheel non-slip control period.
Brake-pressure pressure charging valve 7 constitutes wheel brake pressure modulation valve device with brake-pressure reducer 9; Through this wheel brake pressure modulation valve device,, Hydraulic Pump 10 can realize the independent brake-pressure regulation of each wheel is controlled to carry out vehicle wheel non-slip when being driven with own known and mode that here do not set forth.In vehicle wheel non-slip control, disconnecting valve 3 cuts out, that is, motor vehicle braking system 1 was hydraulically opened with main brake cylinder in 2 minutes.
Can the suction side of Hydraulic Pump 10 be connected with main brake cylinder 2 through the suction valve 14 in each brake circuit I, II.Suction valve 14 is the two-position two-way solenoid valves of cutting out at the initial position of its outage.If suction valve is opened; Hydraulic Pump 10 directly aspirates braking liquid from main brake cylinder 2; Being under the situation of pressurized state not at motor vehicle braking system 1 in other words under the situation of not handling main brake cylinder 2, can form brake-pressure quickly thus through Hydraulic Pump 10.
Main brake cylinder 2 has a brake servo unit 15; This brake servo unit is electromechanical brake servo unit 15 in the present embodiment; This electromechanical brake servo unit produces amplification power by means of electrical motor 16, and this amplification power is handled main brake cylinder 2 jointly with the manpower that applies through brake pedal 17 or other operating elements.Electrical motor 16 with symbolic representation is integrated in the brake servo unit 15.Electrical motor 16 can be a rotary electromotor, and it rotatablely moves and is slowed down through change-speed box, and is converted into the motion of translation that is used to handle main brake cylinder 2.Can also brake servo unit 15 be embodied as and have linear motor or electromagnet.This is enumerated and is not exhaustive.Brake pedal 17 also can be interpreted as the human control element prevailingly.
In order to control or regulate the motor vehicle braking system 1 that comprises brake servo unit 15, be provided with electronic control package 18.The treadle effort that is applied on the brake pedal 17 can be measured through force gauge 19, and position and the speed or the acceleration/accel of brake pedal 17 can be measured through displacement pickup 20.One in two sensors 19,20 is enough.Electronic control package 18 is from the pressure sensor 11 of car side brake 4,5 and from obtaining other signals with main brake cylinder 2 bonded assembly pressure sensors 21.
For normal brake application, step on brake pedal 17, handle main brake cylinder 2 thus and pass through human control motor vehicle braking system 1 via this main brake cylinder.Except manpower, produce amplification power through brake servo unit 15, this amplification power increases actuating force.Realize control through electronic control package 18 according to the signal of force gauge 19 and/or displacement pickup 20.Amplification power can be called as power-assisted in this case.The power amplification of realizing through brake servo unit 15 can be constant or change.The mode itself that realizes anti-skidding controllable function is known and repeats no more here.
At least one car side brake 5 has blocking device 21, can be locked by under the state of handling through this blocking device car side brake 5, thereby this car side brake is not having to keep formed brake-pressure fully under the situation of hydraulic pressure yet.In the present embodiment, two car side brakes 5 have blocking device 21.Blocking device 21 can have the for example electromechanical compressing structure of car side brake 5, have handle with electromechanical, fluid pressure type or pneumatic type and the locking mechanism of releasable machinery or the latch-up structure of frictional connection formula.Blocking device 21 is preferably bistable, that is to say not only at the state of locking down but also be stable under the releasing orientation when not having under the situation that energy imports promptly no current for example.
Hope according to chaufeur is for example handled through handling with the locking of control setup 18 bonded assembly buttons 22 execution motor vehicle braking systems 1.15 pairs of main brake cylinders 2 of brake servo unit apply amplification power, that is, brake servo unit 15 is handled main brake cylinder 2, and via this main brake cylinder maneuver vehicle brake system 1.The hydraulic pressure that forms is in this way handled car side brake 4,5, and said car side brake is compacted through hydraulic pressure.Handle and make the car side brake 5 that blocking device is housed being locked under the operation state to blocking device 21.The thrust of blocked car side brake 5 and braking force are able to continue to keep, even stop brake servo unit 15 energisings and/or said brake servo unit 15 are returned to its initial position.
Can improve the brake-pressure that forms through brake servo unit 15 through connecting Hydraulic Pump 10.This is to be used for: not enough or maybe be not enough the time when the locking braking force of car side brake 5 under situation about only compressing through brake servo unit 15; For example when the power actuated vehicle of the trailer that has hook was parked on the slope, the coarst brake of trailer was inoperative on this slope.In order to improve pressure through Hydraulic Pump 10; Suction valve 14 is opened; Thereby Hydraulic Pump obtains the higher braking liquid of pressure from the main brake cylinder of being handled by brake servo unit 15 2, and disconnecting valve 3 is closed so that make on the pressure side on hydraulic pressure, opening in 2 minutes with main brake cylinder of Hydraulic Pump 10.Do not get rid of the mode that other improve brake-pressure, for example through aspirating brakings liquid from hydraulic accumulator 13 with Hydraulic Pump 10.When the service life of Hydraulic Pump 10 is not to be the set timing of the manipulation of routine, during the locking of motor vehicle braking system 1 is handled, improves the power actuated vehicle that brake-pressures should be limited to the trailer that for example described buckle hangs through Hydraulic Pump 10 and is parked in the exception on the slope.Hydraulic Pump 10 can or be driven during handling main brake cylinder 2 through brake servo unit 15 after this.After car side brake 5 locking, as break and to the energising of brake servo unit 15, turn off Hydraulic Pump 10.
The locking braking force of car side brake 5 another kind of situation not enough or that possibility is not enough when only compressing car side brake 5 through brake servo unit 15 possibly be that the locking to wheel brake system 1 is handled under the situation of main brake cylinder 2 not being carried out human control, promptly when the vehicle driver does not step on to brake pedal 17 during locking is handled.In this case, also can improve the brake-pressure that forms through brake servo unit 15 through Hydraulic Pump 10.Because the vehicle driver in most of the cases steps on to brake pedal 17 with the vehicle that keeps having braked before him the quiescence Shi Douhui that remains static when he triggers the locking braking function, therefore this situation also is a kind of exception.The advantage of this design plan of the present invention is; Brake servo unit 15 can be designed to lower amplification power because amplification power always improves with Hydraulic Pump 10 through manpower or brake-pressure or for example when vehicle is parked on the plane only amplification power be exactly enough.Yet generally speaking also feasible is locking the brake-pressure that glancing impact forms through brake servo unit 15 through Hydraulic Pump 10 raisings, to be when being directed against this design-calculated when the service life of Hydraulic Pump 10.
In order to lock manipulation, a kind of design plan that can be is according to the method for the invention closed the brake-pressure pressure charging valve 7 of the car side brake 4 with blocking device 21.Through closing the brake-pressure pressure charging valve 7 of car side brake 4 with blocking device; These car side brakes 4 were opened with main brake cylinder on hydraulic pressure under the situation that the locking of motor vehicle braking system 1 is handled in 2 minutes, and only were that the car side brake 5 with blocking device 21 is handled.
In order to detect car side brake 5 by the locking under the operation state; Measure through pressure curve in 21 pairs of main brake cylinders of pressure sensor 2 and/or the wheel brake pressure in one or more car side brake 5, and compare with corresponding common pressure curve under locking manipulation situation.If the pressure curve of measuring is different with common pressure curve, can infer so has fault, infers that particularly car side brake 5 is not locked under operation state.When car side brake 4 was opened with main brake cylinder on hydraulic pressure through closing its pressure charging valve 9 or its disconnecting valve 3 during locking is handled in 2 minutes, the deviation of measured pressure curve and common pressure curve was bigger.Especially, when locking when inoperative, the curve of pressure drop be in locked by the car side brake operation state under 5 after, be returned at brake servo unit 15 and then main brake cylinder 2 under the situation of its initial position and change.Such reason is, when blocking device worked, by pretension mechanically and be held pretension, in contrast, when locking was invalid, the pretension of brake servo unit 5 unclamped car side brake 5 under operation state.In order to detect the locking of car side brake 5, can after the hydraulic actuated of its brake-pressure pressure charging valve 7, this brake-pressure pressure charging valve cut out, brake servo unit 15 is resetted, and when opening brake-pressure pressure charging valve 7 subsequently, pressure curve is measured.To car side brake 5 by the measurement of the locking under the operation state or generally speaking test can carry out relatively with other observed reading, the stroke of brake servo unit 15 particularly, the motor revolution of the trip and this brake servo unit is proportional.
Car side brake 5 by the locking under the operation state as cause the mechanical pretension of car side brake 5 implementing, this pretension can clamp blocking device 21, thus locking can only be unclamped through big power.Therefore, a kind of design plan regulation of the present invention in order to unclamp the locking of car side brake 5, is exerted pressure to this car side brake with hydraulic way and pretension mechanically thus through brake activation servo-unit 15.Mechanical pretension unclamps thus or reduces, thereby the locking of car side brake 5 can be unclamped with very little power.
In the vehicle that stops and in the motor vehicle braking system of handling through manpower and/or brake servo unit 15 1; A kind of design plan according to the method for the invention, can close disconnecting valve 3 and/or brake-pressure pressure charging valve 7 and thus wheel brake pressure be comprised in the car side brake 4,5.The load of brake servo unit 15 reduces thus.Closing of disconnecting valve 3 and/or brake-pressure pressure charging valve 7 can for example carried out when the shifter bar of automatic transmission with hydraulic torque converter is set to the Parking position under the situation of maneuver vehicle brake system 1.This design plan of method of the present invention is different with parking braking function.The braking force of car side brake 4,5 will be through being in braking liquid under the pressure and being included in the car side brake 4,5 and being able to keep fully by closing disconnecting valve 3 and/or brake-pressure pressure charging valve 7.
