Error correction brake system of the present invention is to obtain people in the time that automobile is carried out to emergency brake with sensor 9, be excessive too quickly to stepping on pressure, speed or the acceleration/accel of the pedal of stopping, and be different from pressure, speed or the acceleration/accel of step on the accelerator step block in any case, stepped on the judgement key element of Das Gaspedal with answering emergency brake as the normal step on the accelerator of difference by mistake.Sensor 9 is the parts for obtaining throttle step block pressure, speed or acceleration/accel.Transducing signal analyzer 10 is pressure, speed or acceleration/accel electric signal that sensor 9 is obtained depending on not and judge whether to belong to should emergency brake time, has stepped on the problem of Das Gaspedal by mistake.9 of sensors obtain the actuating signal of throttle step block, and transducing signal analyzer 10 is that the actuating signal of step block is analyzed to judgement, only go out to exist while having stepped on Das Gaspedal by mistake, and transducing signal analyzer 10 is just to control signal amplifirer 11 output signals.Once transducing signal analyzer 10 is to control signal amplifirer 11 output signals, the action that wrong step on the gas pedal is described need to be corrected as brake, so control signal amplifirer 11 enough starts the electric energy of 18 one-tenth closure states of electromagnetic switch to electromagnetic switch 18 outputs of power-supply controller of electric 12, the electric energy that makes the inside fork-shaped rotor of direct supply 15 provide brake to need for the electromagnetic valve 14 of fixing corner, interior fork-shaped rotor is that the electromagnetic valve 14 of fixing corner produces the forward action that brake needs.As with stay cord 8 by interior fork-shaped rotor be fixing corner electromagnetic valve 14 central rotating shaft 3 be connected with the braking mechanism of automobile, this electromagnetic valve just can be carried out the action that pulls other system of brake pedal or brake to carry out a whole set of emergency brake.After automobile is checked, driver thinks that danger removes, can normally travel, driver can only move the manual type automatic gear returning switch 19 that electromagnetic valve is resetted, the inside fork-shaped rotor of direct supply 15 is that the electromagnetic valve 14 of fixing corner is oppositely powered, interior fork-shaped rotor is that the electromagnetic valve 14 of fixing corner is just reset, and makes other system of brake pedal or brake also reset to the position of not braking, and automobile can normally travel again.In addition, because the electromagnetic switch 18 and the manual type automatic gear returning switch 19 that start electromagnetic valve work are all the switches that adopts normal off to open, after control signal amplifirer 11 finishes the starting current of electromagnetic switch 18, electromagnetic switch 18 is got back to off-state automatically, direct supply 15 disconnects with the electromagnetic valve 14 that interior fork-shaped rotor is fixing corner, but the electromagnetic valve 14 that interior fork-shaped rotor is fixing corner also remains on the state that brake needs; When driver manually moves the manual type automatic gear returning switch 19 that electromagnetic valve is resetted, making interior fork-shaped rotor is that the electromagnetic valve 14 of fixing corner resets to after the state that does not need brake, manual type automatic gear returning switch 19 is got back to again off-state automatically, direct supply 15 disconnects with the electromagnetic valve 14 that interior fork-shaped rotor is fixing corner, makes whole error correction brake system be returned to again the state in awaiting orders.
In error correction brake system core component of the present invention, fork-shaped rotor is that the structure of fixing the electromagnetic valve 14 of corner is described as follows:
The opposite face meaning that the opposite face of overcoat fixed body 2 arc inner walls is provided with a pair of permanent magnetic iron block 4 is: this pair of permanent magnetic iron block 4 is at the opposite face of a certain diameter of overcoat fixed body 2.
In the time that whole coils 6 are all non-conductive, in " ten " font iron core 5, always have the two ends of a straight shape iron core 7 to be attracted by two block permanent magnet pieces 4 of overcoat fixed body 2 interior opposite faces, the two ends that make this straight shape iron core 7 from two block permanent magnet pieces 4 very close to.And in " ten " font iron core 5 two ends, two ends of another straight shape iron core 7 from two block permanent magnet pieces 4 away from.
The principle that interior fork-shaped rotor 1 corner is fixed value is: in " ten " font iron core 5, the coil 6 on two straight shape iron cores 7 that one-tenth " ten " word intersects, after conduction, makes the two poles of the earth of two straight shape iron cores 7 all become the magnetic pole of electromagnet.If after the coil 6 of first attraction by two block permanent magnet pieces 4 in quiescence above straight shape iron core 7 conducts electricity, make two electromagnetism magnetic poles of this straight shape iron core 7 become the arctic to the South Pole with the magnetic pole of two block permanent magnet pieces 4, because opposite pole attracts mutually, interior fork-shaped rotor 1 just can not relatively rotate with overcoat fixed body 2, and interior fork-shaped rotor 1 can not rotate.But after the coil 6 of first attraction by two block permanent magnet pieces 4 in quiescence above straight shape iron core 7 conducts electricity, making two electromagnetism magnetic poles of this straight shape iron core 7 become one end with the magnetic pole of two block permanent magnet pieces 4 is that the arctic is to the arctic, the other end is that the South Pole is to the South Pole, because like pole repels mutually, the relative permanent magnetic iron block 4 of two south poles that is fixed on overcoat fixed body 2 inner faces can repel first straight shape iron core 7, and second straight shape iron core 7 of attraction, the magnetic pole South Pole of second straight shape iron core 7 and permanent magnetic iron block that magnetic pole is the arctic 4 are approached, make the magnetic pole arctic of second straight shape iron core 7 and permanent magnetic iron block that magnetic pole is the South Pole 4 approach simultaneously.Like this, the relative permanent magnetic iron block 4 of two south poles in overcoat fixed body 2 repels first straight shape iron core 7 to push away far, second the straight shape iron core 7 that simultaneously attracts again magnetic pole to inhale mutually, thereby " ten " font iron core 5 of interior fork-shaped rotor 1 and two block permanent magnet pieces 4 in overcoat fixed body 2 are produced relative rotation, reach the object that interior fork-shaped rotor 1 is rotated.Because overcoat fixed body 2 is fixed on other motionless object, interior fork-shaped rotor 1 can be used as propulsion source and drives other movable object, pulls the propulsion source of brake-pedal of automobile as can be used as.
In the time that whole coils 6 are all non-conductive, the angle between the straight shape iron core 7 at the opposite magnetic pole end place of first straight shape iron core 7 and second straight shape iron core 7, is exactly the constant rotation angle of interior fork-shaped rotor 1.Because two straight shape iron core 7 angles in " ten " font iron core 5 are constant, the pivot angle of interior fork-shaped rotor 1 is exactly the numerical value of this angle, can not change.It is a definite value that " ten " font iron core 5 makes the pivot angle of interior fork-shaped rotor 1, and different angles " ten " font iron core 5 makes the pivot angle difference of interior fork-shaped rotor 1.If change the output pivot angle of interior fork-shaped rotor 1, must to change the angle of " ten " font iron core 5 interior two straight shape iron cores 7.

It is the electromagnetic valve 14 of fixing corner for different interior fork-shaped rotors, 7 one-tenth 1 ~ 179 of two straight shape iron cores degree angles of " ten " font iron core 5 all can, different interior fork-shaped rotors is that the rotatable angle of interior fork-shaped rotor 1 of 14 two straight shape iron core 7 outsides of electromagnetic valve of fixing corner is 1 ~ 179 to spend and all can.Namely different interior fork-shaped rotors be some values in 7 one-tenth 1 ~ 179 degree angular range of 14, two straight shape iron cores of electromagnetic valve of fixing corner all can, the rotatable angle of interior fork-shaped rotor 1 is that the some values within the scope of 1 ~ 179 degree all can.
Straight shape iron core 7 is " work " font.Make the two ends of straight shape iron core 7 more roomy, prevent that coil 6 from skidding off from the termination of straight shape iron core 7.
On same straight shape iron core 7, have two or more coils 6, these two or more coils 6 around to identical.Coil 6 on straight shape iron core 7 is to make straight shape iron core 7 produce the effect of electromagnet, in order to make the condition of the whole coils 6 on straight shape iron core 7 in identical conduction amount, allows this straight shape iron core 7 produce maximum magnetic flow, all coils 6 around to just should be identical.
Interior fork-shaped rotor is that central rotating shaft 3 outside faces of the interior fork-shaped rotor 1 of electromagnetic valve 14 of fixing corner are connected with one end of stay cord 8.Stay cord 8 is devices that interior fork-shaped rotor 1 is exported rotation displacement and rotation strength.
" fixing " two word implications of overcoat fixed body 2 are in working order, overcoat fixed body 2 is to be fixedly connected with other the fixed object beyond the present invention, make the overcoat fixed body 2 can be because of to the present invention power supply and do not move, other fixed object be as car crust, geodetic ground etc.
Interior fork-shaped rotor of the present invention is that electromagnetic valve 14 preferred structures of fixing corner are as follows:
Interior fork-shaped rotor is 7 one-tenth 1 ~ 179 degree angles of two straight shape iron cores of " ten " font iron core 5 of the electromagnetic valve 14 of fixing corner.
It is the electromagnetic valve 14 of fixing corner for different interior fork-shaped rotors, 7 one-tenth 1 ~ 179 of two straight shape iron cores degree angles of " ten " font iron core 5 all can, different interior fork-shaped rotors is that the rotatable angle of the interior fork-shaped rotor 1 of electromagnetic valve 14 of fixing corner is 1 ~ 179 to spend and all can.Namely different interior fork-shaped rotors be some values in 7 one-tenth 1 ~ 179 degree angular range of 14, two straight shape iron cores of electromagnetic valve of fixing corner all can, the rotatable angle of interior fork-shaped rotor 1 is that the some values within the scope of 1 ~ 179 degree all can.
Interior fork-shaped rotor is that the straight shape iron core 7 of the electromagnetic valve 14 of fixing corner is " work " font; Interior fork-shaped rotor is to have two or more coils 6 on the same straight shape iron core 7 of electromagnetic valve 14 of fixing corner, these two or more coils 6 around to identical.
Make the two ends of straight shape iron core 7 more roomy, prevent that coil 6 from skidding off from the termination of straight shape iron core 7.Coil 6 on straight shape iron core 7 is to make straight shape iron core 7 produce the effect of electromagnet, in order to make the condition of the whole coils 6 on straight shape iron core 7 in identical conduction amount, allows this straight shape iron core 7 produce maximum magnetic flow, all coils 6 around to just should be identical.
Interior fork-shaped rotor is that central rotating shaft 3 outside faces of the interior fork-shaped rotor 1 of electromagnetic valve 14 of fixing corner are connected with one end of stay cord 8.
If connect stay cord 8 on the central rotating shaft 3 of interior fork-shaped rotor 1, the exportable straight-line motion of stay cord 8 other end, if establish gear on central rotating shaft 3, exportable straight-line displacement or circular movement.
Advantage of the present invention: by installation of sensors of the present invention in the position that can obtain automobile accelerator pedal or throttle system action actuating signal, the central rotating shaft stay cord or the alternate manner that are the interior fork-shaped rotor of the electromagnetic valve of fixing corner by interior fork-shaped rotor of the present invention are connected with brake-pedal of automobile or brake system, just making this automobile become can be by driver in the time answering emergency brake, has stepped on Das Gaspedal by mistake and has converted the safety automobile that emergency brake is moved to.From find mistake step on the gas to be corrected as brake fast response time, drive brake electromagnetic valve action accurately, do not have stall problem, can be for a long time in braking state, can realize full automaticity error correction and start brake and hand reset, hand reset is not placed restrictions on the time of braking state.
The present invention can be automatically convert mistake step on the gas signal to pull the mechanical action that drives brake pedal or its mechanism to, can automatically reset, and for use and get ready next time, again can manual reset, to ensure the braking time of artificial needs.And automatic error-correcting brake, there is same system with automatically reset and manual reset etc.
The present invention uses electromagnetic valve as actuating unit, than with electrical motor as the advantage of actuating unit being: electromagnetic valve power delivery curve of the present invention is to keep Cheng Pingwen straight line after jumping 0.01 ~ 0.05 moment in second, the dynamic curve of brake pedal or its mechanism's needs while being just in time applicable to emergency brake, namely the working curve of electromagnetic valve is identical with the working curve that brake needs, and the emergency brake that completes that just can be best is moved.And be all as actuating unit with electrical motor in the error correction brake system technology of existing mistake step on the gas, and motor power delivery curve needs strength for wanting just can reach emergency brake after arc rising slowly 1.50 ~ 2.50 seconds, the working curve of electrical motor is not identical with the working curve that brake needs, can not well realize urgent needs, make length, braking distance prolongation of braking time, thereby the possibility having an accident is higher.
In the present invention fork-shaped rotor be the advantage of the electromagnetic valve of fixing corner be a kind of fast response time, can have dynamic and static two kinds of mode of operations, that place restrictions on pivot angle, have fixed starting-point and telemechanical track, do not have stall problem, power stage is close to the movement in a curve electromagnetic valve of steady state value:
［ 1 ］ fast response time: so starting emergency brake and making brake pedal reach only 0.01 ~ 0.05 second needed time of complete braking state with the automobile of error correction brake system of the present invention, its reason is that the central rotating shaft of the interior fork-shaped rotor of electromagnetic valve can directly be connected with brake pedal or brake system with stay cord, and existing various mistake step on the gas error correction brake system is all to pass through the mechanicals device such as change-speed box, displacement limiter as intermediary movements transmission with the turning cylinder of electrical motor, and consume the time of protecting expensive startup brake pedal most.In the present invention, fork-shaped rotor is why the interior fork-shaped rotor central rotating shaft of fixing the electromagnetic valve of corner can start in 0.01 ~ 0.05 second brake pedal, because after energising, coil in electromagnetic valve can produce galvanomagnetic effect within 0.01 second, and makes interior fork-shaped rotor be subject to magnetic action and rotate.
［ 2 ］ there are dynamic and static two kinds of mode of operations: when moving mode of operation refers to start emergency brake, drive brake pedal or other braking mechanism thereby power supply rotates rapidly the rotor of electromagnetic valve.Quiet mode of operation refers to that solenoid-driven brake pedal or other braking mechanism are after normal danger, electromagnetic valve can not wanted power supply still can keep loading mode of operation, when power supply still can not make brake pedal or other braking mechanism infinitely, remains on braking state.Because no matter electromagnetic valve, after once electrification, is to keep energising or power-off, the rotor of electromagnetic valve to keep motionless, can make to be driven object forever to remain on fixed position.If allow electromagnetic valve power-off, keep for a long time a certain state not need power consumption, be a kind of energy-saving machinery design.Existing motor "on" position essential maintenance rotate, if placed restrictions on rotation, produce stall problem, not only power consumption, and may in seconds generate heat and burn out motor.Electromagnetic valve of the present invention is can also export certain strength without power consumption to keep object in a certain location status and there is no stall problem.
［ 3 ］ the power delivery curve of applicable emergency brake needs: electromagnetic valve is starting 0.01 ~ 0.05 moment in second of energising, horsepower output can approach maximum output power value, output power value between whole motor area, close to steady state value, that is to say steady straight line work of basic one-tenth.And the output power value of existing motor is the arc working curve large from little change.The mode of these two kinds of horsepower outputs respectively has purposes, and electromagnetic valve of the present invention is suitable for the mechanical problem of emergency driving.
［ 4 ］ electricity can be only as the use that changes sense of motion, and be not used in load: on fork-shaped fixed body around coil in the effect of magnetic force that initial condition produces of conduction, mainly to make rotor turn to another dead position from a dead position, be that the power Main Function that coil produces is the sense of motion that changes rotor, the power that coil produces is not to be mainly used in driving load, so the strength of inputting very little energy and just can using permanent magnet, makes rotor obtain very large turning effort.Again because this electromagnetic valve stablize strength output state and can not be consumed energy by no power keeping, thus this electromagnetic valve be save the energy, have environment protection significance, start fast, export fast high-power, power stage steady, rotational angle is accurate, the accurate electromagnetic valve of output displacement length.
［ 5 ］ forced stroke is accurate: after once electrification, the rotor of electromagnetic valve only rotates some angles of 1 ~ 179 degree, the pivot angle of an electromagnetic valve is a changeless value, and scope is in 1 ~ 179 degree, and this machinery that limits displacement for ask for something is best propulsion source.Having saved rotation-limited electrical motor places restrictions on the mechanism that electrical motor rotates or makes mechanical drive produce to skid with additional mechanical and place restrictions on the mechanism of rotation.
［ 6 ］ volume is little lightweight: if stroke reaches 6 centimetres, and 50 kilograms of starting loads, weight needs only 2 kilograms, and volume needs only long 15 centimetres of 10 centimetres of * of diameter, and cost is extremely low, and not power consumption of static load, on automobile, can have installation site, practical.If but general electromagnetic valve stroke reaches 6 centimetres, 50 kilograms of starting loads, weight is wanted more than 100 kilograms, volume wants 20 centimetres of * of diameter long more than 30 centimetres, and cost is high, and static load power consumption, there is no so large installation site at automobile, can not serve as error correction brake system and use.

Detailed description of the invention
The S. A. error correction brake system of embodiment 1, interior rotatable fixing angle electromagnetic valve
As Fig. 1,2,3, comprise the sensor 9---transducing signal analyzer 10---control signal amplifirer 11---power-supply controller of electric 12 being connected successively in order to transmit electric signal, with for electric energy conversion is become to mechanical energy, and with power-supply controller of electric 12 be connected with interior fork-shaped rotor be the electromagnetic valve 14 of fixing corner is connected with power-supply controller of electric 12 drive in fork-shaped rotor be the direct supply 15 of fixing the electromagnetic valve 14 of corner.
The explanation to each parts below:
Sensor 9 is a certain of pressure sensor, speed sensor or acceleration pick-up or its combination; Transducing signal is transferred to transducing signal analyzer 10 by sensor 9.In other words, sensor 9 is a certain with in pressure sensor, speed sensor or acceleration pick-up, also can be that pressure sensor, speed sensor and acceleration pick-up all use, even can also there is the rang sensor of Slope Transducer and mensuration and encumbrance distance, the output signal of these different sensors is all transferred to respectively to transducing signal analyzer 10, transducing signal analyzer 10 is analyzed the signal of various sensors, judges whether to belong to should brake time and has stepped on throttle by mistake.
Transducing signal analyzer 10 use can receive the micro controller system of signal, energy calculation process signal and energy output signal.In transducing signal analyzer 10, be set with a certain of pressure threshold switch, threshold speed switch or acceleration rate threshold switch; In the time judging whether wrong step on the gas behavior by single factor, each switch value is for comparing with corresponding sensor signal value, as pressure threshold switch receives only the pressure signal that pressure sensor is inputted.In the time that transducing signal is less than switch value, while being less than the threshold value of pressure switch as pressure signal value, transducing signal analyzer 10 is considered as not step on the gas behavior by mistake, not output signal of transducing signal analyzer 10; In the time that transducing signal is greater than switch value, while being greater than the threshold value of pressure switch as pressure signal value, transducing signal analyzer 10 is considered as wrong step on the gas behavior, and transducing signal analyzer 10 starts brake signal to 11 outputs of control signal amplifirer.If but undertaken multifactor while judging whether wrong step on the gas behavior by pressure, speed, acceleration/accel, the gradient and distance, in transducing signal analyzer 10, should be provided with the function model of these factors as variable, these factors of various sensor inputs are carried out to computing with the function model of having set, judge whether wrong step on the gas behavior, just output signal not of step on the gas behavior by mistake of judgement, but in the time getting the wrong sow by the ear step on the gas behavior, transducing signal analyzer 10 starts brake signal to 11 outputs of control signal amplifirer.
