Error correction brake system of the present invention is to obtain people when automobile is carried out to emergency brake with sensor 9, to stepping on pressure, speed or the acceleration/accel of the pedal of stopping, be excessive too quickly, and be different from pressure, speed or the acceleration/accel of step on the accelerator step block in any case, as the normal step on the accelerator of difference, stepped on the judgement key element of Das Gaspedal with answering emergency brake by mistake.Sensor 9 is for obtaining the parts of 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 actuating signals of obtaining throttle step block of sensor, and transducing signal analyzer 10 is that the actuating signal of step block is analyzed to judgement, only goes out to exist while having stepped on Das Gaspedal by mistake, transducing signal analyzer 10 is just to control signal producer 11 output signals.To storing in control signal producer 11 while implementing emergency brake, the control electromagnetic valve needing is the signals of action all; Once transducing signal analyzer 10 is to control signal producer 11 output signals, the action that wrong step on the gas pedal is described need to be corrected as brake, so control signal producer 11 is carried out the signal of whole actions of brake at once to a whole set of driving electromagnetic valve of power-supply controller of electric 12 output.Power-supply controller of electric 12 is the whole actuating signals power-supply controller of electric 12, become successively in chronological order internal fork-shaped rotor and carry out the equipment of various power transmission modes for the fixing electromagnetic valve 14 of corner, power-supply controller of electric 12 is a whole set of whole actuating signals to be become to the conversion equipment of the signal variable power transmission of a whole set of whole power transmission modes.Interior fork-shaped rotor for the fixing electromagnetic valve 14 of corner be one by the machinery of power drives, the equipment moving such as controlled by power-supply controller of electric 12 to forward and reverse, stop; As being that fixedly the electromagnetic valve 14 of corner is connected with the braking mechanism of automobile with stay cord 8 by interior fork-shaped rotor, this electromagnetic valve pulls other system of brake pedal or brake to carry out the action of a whole set of emergency brake with regard to carrying out.

In error correction brake system core component of the present invention, fork-shaped rotor is that fixedly the structure of 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.

When 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, become coil 6 on two straight shape iron cores 7 that " ten " word intersects after conduction, make the two poles of the earth of two straight shape iron cores 7 all become the magnetic pole of electromagnet.If after coil 6 conductions of first attraction by two block permanent magnet pieces 4 in quiescence above straight shape iron core 7, 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 coil 6 conductions of first attraction by two block permanent magnet pieces 4 in quiescence above straight shape iron core 7, 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.

When 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 of interior fork-shaped rotor 1 different.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.

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.

For different interior fork-shaped rotors, it is the fixing electromagnetic valve 14 of corner, 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 for the fixing rotatable angle of interior fork-shaped rotor 1 of 14 two straight shape iron core 7 outsides of electromagnetic valve of corner be 1 ~ 179 to spend and all can.14, two straight shape iron cores of electromagnetic valve that namely different interior fork-shaped rotors is fixing corner spend for 7 one-tenth 1 ~ 179 some values in angular range 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 the effects that make straight shape iron core 7 produce electromagnet, in order to make the whole coils 6 on straight shape iron core 7 in the condition of identical conduction amount, allows this straight shape iron core 7 produce maximum magnetic flow, all coils 6 around to just should be identical.

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 Huo Qi mechanism 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 braking time length, braking distance prolongation, thereby the possibility having an accident is higher.

In the present invention fork-shaped rotor for the fixing advantage of the electromagnetic valve of 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 0.01 ~ 0.05 second only 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 transmit as intermediary movements by mechanicals device such as change-speed box, displacement limiters with the turning cylinder of electrical motor, and consumed the time of protecting expensive startup brake pedal most.In the present invention, fork-shaped rotor is that fixedly why the interior fork-shaped rotor central rotating shaft of 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, thereby power supply rotates rapidly the rotor of electromagnetic valve, drive brake pedal or other braking mechanism.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 driven object forever 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 ］ be applicable to the power delivery curve of 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 from the large arc working curve of 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 input very little energy, just can use the strength of permanent magnet, make rotor obtain very large turning effort.Again because this electromagnetic valve can not consume energy by no power keeping stablize strength output state, 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.But if 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, at automobile, there is no so large installation site, can not use as error correction brake system.
