Description

Pressure-triggered switch-type accelerator pedal system for correcting throttle as brake

The invention belongs to the technical field of the automobile throttle system, in particular, the throttle system capable of directly obtaining the throttle signal by mistake, and can convert the accidental accelerator action into the throttle device for driving the brake machine.

Background technique

The applicant has provided in his own authorized patent 20051001077.X "Throttle system device with an annunciator" a device for determining whether to correct the brake after correct or incorrect operation of the throttle, so that the throttle becomes available. Braking accelerates the dual-purpose motor vehicle accelerator pedal system. It is characterized in that an annunciator is provided on any one of the accelerator pedal, the linkage, and the accelerator pedal corresponding to the body part device. The annunciator is connected to an electric valve that cuts off the engine oil circuit and an electric valve that activates the brake. The technology proposes to use electronic settings to sense the false pedal action and output a brake signal to the electric valve on the oil circuit and the electric valve on the wheel brake to achieve remedial braking. One of the shortcomings of this technique is that in the continuously varying pressure signal experienced by the annunciator, when the signal acquisition device that judges or takes out the accelerator pedal signal is faulty, the judgment of the false pedal accelerator signal may be incorrect, resulting in the system. Poor reliability. The second disadvantage of this technology is that the electric valve is controlled by the signal output line, and the engine fuel supply pipe, the ignition circuit, the motor power supply, etc. of the vehicle are turned off by the electric valve, so that the driver has accidentally stepped on the throttle to a long time when the vehicle is stopped, the vehicle The trip that produces the error is far away, and this kind of unresponsiveness is not good for stopping the accident. The third disadvantage of this technology is that the electric valve is controlled by the signal output line, and the engine fuel supply pipe, the ignition circuit, the motor power supply, etc. of the vehicle are turned off by the electric valve, so that the engine completely stops rotating and stops working, resulting in the braking system and steering of the automobile. The safety system such as the system and anti-skid stops working. Therefore, shutting down the engine of the vehicle with the accidental throttle signal is not conducive to correcting the emergency brake when the throttle is accidentally stepped.

The applicant disclosed a device including a sensor, a signal analyzer and a brake starting mechanism in his patent application 201110030092.4, "Electrical and mechanical cooperation to automatically correct the throttle to the brake device", and the disadvantage is that the error is obtained. There are many microelectronic devices for stepping on the throttle signal, and the reliability is degraded. The shortcoming is that in the brake starting mechanism, the circular motion of the motor is changed into the reciprocating motion of the brake rope, and the straight rack is used to change the movement mode. To ensure the reciprocating motion of the straight rack positioning, it is necessary to have a frame that fixes the relative position of the motor and the straight rack. This type of frame is bulky and difficult to find a suitable position to install, and has a complicated structure, high cost, and poor reliability.

Summary of the invention

The object of the present invention is to provide a throttle system that simply and accurately outputs an electric signal for accidentally stepping on a throttle action, and is capable of collecting a throttle system that is accidentally stepped on a throttle action and outputted by an electric signal, and drives an electric signal that is accidentally stepped on the throttle. Throttle system for emergency error correction devices.

The idea of the invention is that a person may make a false pedaling action when panicked, and the accelerator pedal action must cause the accelerator pedal and the associated mechanism to generate a different motion from the normal fueling, that is, the accelerator pedal and the associated mechanism must be Will suffer To the power of too much. The force of people stepping on the accelerator pedal is generally less than 5 kg. The force of accidentally stepping on the throttle is generally greater than 10 kg. After many experiments, the pedal is subjected to the pressure of 10 kg as the false threshold when the throttle is accidentally stepped, which distinguishes the normal refueling action and error. The throttle action is reasonable, applicable, and safe. Therefore, it is only necessary to set the pressure switch on the accelerator pedal and its associated mechanism. When the force of the accelerator pedal is greater than or equal to the false pedal threshold of 10 kilograms, the pressure switch is turned on, and the electric signal of the throttle is accidentally depressed. The pressure switch does not need to be able to Feel the movement state of the accelerator pedal that is smaller than the false pedal threshold, and simplify the method of collecting the accidental accelerator pedal. Therefore, only when there is more than or equal to 10 kg of accelerator power, the two conductive points of the pressure switch are in contact with the electrical signal, and the switchable electrical signal can be used to indicate whether the throttle is actuated. Therefore, this patent refers to this pressure switch as the pressure trigger switch 1. Of course, using the force of 10 kg to step on the throttle triggers the pressure trigger switch 1 not necessarily suitable for some special people. For special people, the elastic components with different elastic coefficients can be used, and the switching threshold of the pressure trigger switch 1 is changed, thereby changing the false pedal of the accelerator pedal. Threshold.

In the prior application [201120189726.6], which claims priority from the present application, the "pressure type low-voltage electric switch" is used to recognize the malfunctioning throttle operation, and the "pressure type low-voltage electric switch" does not describe the elastic element. Based on the position of the prior application "pressure type low voltage electric switch", the present application changes, increases, and clarifies the position of the pressure trigger switch 1 and the elastic member, and further clarifies the structure of the pressure trigger switch 1, and the pressure. The connection structure of the trigger switch 1 and the existing accelerator pedal linkage system.

The structure of the invention is:

In order to correct the throttle, the pressure-triggered switch-type accelerator pedal system for braking, including the accelerator pedal 16 of the automobile and the body portion 21 corresponding to the accelerator pedal 16; or the body portion corresponding to the accelerator pedal link 17 and the accelerator pedal link 17 21, characterized in that: further includes a trigger signal converter 35 connected to the pressure trigger switch 1 and the pressure trigger switch 1;

a pressure trigger switch 1 is provided on the front surface of the accelerator pedal 16;

Or a pressure trigger switch 1 is disposed on the back surface of the accelerator pedal 16, and a normal fueling interval space is left between the pressure trigger switch 1 and the body portion 21 corresponding to the accelerator pedal, and when the accelerator pedal 16 is displaced to the state where the force is at the false threshold value Position, the pressure trigger switch 1 is in contact with the body portion 21 corresponding to the accelerator pedal;

Or the body part 21 corresponding to the accelerator pedal 16 is provided with a pressure trigger switch 1, a pressure trigger switch 1 and an accelerator pedal

Between 16 and 16, the accelerator pedal 16 is left in the space required for the normal refueling movement. When the accelerator pedal 16 is displaced to the position where the force is in the false threshold state, the pressure trigger switch 1 is in contact with the accelerator pedal 16;

Or a pressure trigger switch 1 is provided on the surface of the accelerator pedal connecting rod 17 facing the vehicle body.

Or a pressure trigger switch 1 is provided at a body portion 21 corresponding to the accelerator pedal link 17;

The minimum force acting on the accelerator pedal 16 by the accidental accelerator action is the false pedal threshold of the throttle pedal; when the two contacts of the pressure triggering switch 1 can be in contact with the conduction, the elastic component elastic force of the pressure triggering switch 1 is the switching threshold; Trigger on The position set by the switch 1 makes the switch threshold just express the false pedal threshold, that is, the position set by the pressure trigger switch 1 makes the switch threshold correspond to the false pedal threshold;

The pressure trigger switch 1 is a switch in which the two conductive contacts 25 of the switch can be contacted after the elastic element is deformed by the switching threshold pressure to generate a conductive switch;

The pressure trigger switch 1 is connected to the trigger signal converter 35, and the trigger signal converter 35 converts the trigger signal of the pressure trigger switch 1 into a control signal output.

The body portion 21 corresponding to the accelerator pedal 16 refers to a fixed component position region pointed by the fueling movement direction of the accelerator pedal 16 in the normal fueling state of the automobile, and is a fixed component position region to which the accelerator pedal 16 is refueling. .

The body portion 21 corresponding to the accelerator pedal link 17 refers to a fixed component position region pointed by the direction of the fueling movement of the accelerator pedal link 17 in the normal fueling state of the automobile, and is a refueling movement of the accelerator pedal link 17 Close to the fixed component location area.

The pressure trigger switch 1 selects the elastic switch suitable for the elastic element to set the pressure switch threshold. If the force of the pedal accelerator pedal 16 is greater than or equal to 10 kg, the false pedal threshold of the accelerator pedal 16 is set, and the false threshold value causes the pressure trigger switch 1 The electrically conductive switch 1 is biased as a switching threshold. In the switching threshold state, the pressure trigger switch 1 is turned on. The force of the foot pedal pedal 16 is less than the false pedal threshold, the pressure trigger switch 1 is less than the switch threshold, the pressure trigger switch 1 is turned off, and the throttle is normally refueled to increase the vehicle speed.

As long as the two conductive contacts 25 of the pressure trigger switch 1 are connected to the power source, the pressure trigger switch 1 can output an electrical signal when the two conductive contacts 25 are in contact. The electrical signal acts as a sign of the behavior of the accelerator pedal being mistakenly stepped on, and serves as a start signal for correcting the accidental throttle action.

That is to say, the minimum force that enables the two contacts of the pressure trigger switch 1 to contact the conduction is not necessarily equal to the minimum force emitted by the person when the throttle is accidentally depressed. To use the two contacts of the pressure trigger switch 1 to contact the conductive output signal to indicate that the throttle action is incorrectly stepped, the position set by the pressure trigger switch 1 and the minimum force capable of contacting the conductive [ie, the switching threshold] are used. In order to correctly represent the minimum force (ie, the false pedal threshold) issued by the person when the throttle is accidentally stepped on. That is to say, the false pedal threshold of the accidental depression of the throttle is a combination of the position set by the pressure trigger switch 1 and the switching threshold to indicate the false pedal threshold. If the false pedal depression threshold is 10 kg, the pressure trigger switch 1 is disposed on the accelerator pedal link 17 between the accelerator pedal 16 and the accelerator pedal 16 rotation point, since the force of the pressure trigger switch 1 is shorter than the accelerator pedal 16 According to the principle of leverage, when the switch threshold, that is, the two contacts of the pressure trigger switch 1 can be in contact with the conductive, the minimum elastic force of the elastic element of the pressure trigger switch 1 should be greater than 10 kg. If the false pedal threshold is set to 10 kg, but the pressure trigger switch 1 is set to a different position, the switching threshold of the elastic element is also different. In general, the false pedal depression threshold is not equal to the switching threshold of the elastic component. Therefore, a pressure-triggered switch 1 with a fixed switching threshold can only be set on the accelerator pedal. 16 or a specific position of the accelerator pedal link 17 can make the pressure trigger switch 1 work normally, that is, the switch threshold can accurately express the false pedal threshold, that is, the position set by the pressure trigger switch 1 makes the switch threshold correspond to the false pedal threshold.

The pressure trigger switch 1 is for sensing the force applied to the accelerator pedal 16 and the accelerator pedal link 17, so that the pressure trigger switch 1 can be provided on the surface of the accelerator pedal 16 or the accelerator pedal link 17 facing the vehicle body, or at the accelerator pedal 16 or the body portion 21 corresponding to the accelerator pedal link 17 is provided with a pressure trigger switch 1.

Since the pressure trigger switch 1 is disposed on the accelerator pedal link 17, or the two positions on the body portion 21 corresponding to the accelerator pedal link 17, the foot blanket on the floor of the cab can be avoided, and the falling object hinders the pressure trigger switch 1 Normal force. The pressure trigger switch 1 is provided on the surface of the accelerator pedal link 17 facing the vehicle body from the pressure trigger switch 1 in terms of the reliability of the accelerator pedal operation, or is provided in the body portion 21 corresponding to the accelerator pedal link 17 reliability.

The switch signal output line of the pressure trigger switch 1 is connected to the signal access end of the trigger signal converter 35, that is, the pressure trigger switch 1 is connected to the trigger signal converter 35, and the trigger signal converter 35 converts the trigger signal of the pressure trigger switch 1 into Control signal output. If the control signal is a control signal for controlling the control of the throttle mechanism, the control model of the control signal is such that the control throttle mechanism 36 causes the engine to immediately be in an idle state, so that the automobile engine loses the ability to drive the vehicle, but the automobile engine Keeping the idling state of operation, you can also provide the power needed by the safety system such as the brake system of the car.

The pressure trigger switch 1 is a spring type pressure trigger switch 1 or a disc type pressure trigger switch:

The spring type pressure trigger switch 1 includes a sliding cylinder 26, an inner hollow coil spring 27, a cross piston 28 and two conductive contacts 25; an inner hollow coil spring 27 is disposed in the sliding cylinder 26, and an inner hollow coil spring 27 The two ends respectively contact the bottom of the sliding cylinder 26 and the piston disk of the cross-shaped piston 28; the piston disk of the cross-shaped piston 28 is located at the top of the sliding cylinder 26, and the center pillar 29 of the cross-shaped piston 28 extends out of the sliding cylinder 26 a middle hole of the top cover 31 of the middle hole, a top end of the protruding portion of the center pillar 29 is provided with a force receiving block 30, and another segment of the center pillar 29 of the cross-shaped piston 28 is located in a ring of the inner hollow coil spring 27, the center pillar 29 is provided with a conductive contact 25 at the end of the spring ring; a conductive contact 25 is also fixed in the inner coil spring 27 of the bottom of the slide 26; the conductive contact 25 and the slide of the end of the center pillar 29 There is a slight gap between the conductive contacts 25 at the bottom of the 26 and the positions correspond.

The spring type pressure trigger switch 1 selects the pressure switch threshold value by using a spring suitable spring coefficient. If the force of the foot accelerator pedal 16 is greater than or equal to 10 kg, the false pedal threshold of the accelerator pedal 16 is set, and the false pedal threshold makes the spring pressure The spring that can be turned on by the trigger switch 1 is used as a pressure switch threshold, and the switch threshold is when the spring 27 is compressed to a position where the conductive contact 25 at the end of the center pillar 29 can contact the conductive contact 25 at the bottom of the slider 26. The spring 27 is subjected to a force value. In the switching threshold state, the spring type pressure trigger switch 1 is turned on. When the force of the accelerator pedal 16 is less than the false threshold of 10 kg, the spring-type pressure trigger switch 1 is less than the switch threshold, the spring-type pressure trigger switch 1 is turned off, and the throttle is normally refueled to increase the vehicle speed. The disc type pressure trigger switch 1 includes an elastic concave block 33, an inelastic bottom plate 34 and two conductive contacts 25; the concave portions of the elastic concave block 33 are fixedly connected to each other in the direction of the inelastic bottom plate 34, and the elastic concave block 33 and the inelastic In the inner space of the bottom plate 34, one conductive contact 25 is fixed on the surface of the elastic concave block 33, and the other conductive contact 25 is fixed on the surface of the inelastic bottom plate 34; there is a small gap between the two conductive contacts 25 and the position correspond.

The disc type pressure trigger switch 1 selects the elastic switch coefficient suitable for the elastic concave block to set the pressure switch threshold. If the force of the pedal accelerator pedal 16 is greater than or equal to 10 kg, the false pedal threshold of the accelerator pedal 16 is set, and the threshold is caused by the false pedal threshold. The elastic concave block 33 of the type pressure trigger switch 1 is biased as a pressure switch threshold, and the switch threshold is the elastic concave block 33 when the elastic concave block 33 and the two conductive contacts 25 on the inelastic bottom plate 34 are in contact with each other. Force value. In the switching threshold state, the disc pressure trigger switch 1 is turned on. When the force of the accelerator pedal 16 is less than the false pedal threshold of 10 kg, the force of the disc pressure trigger switch 1 is less than the switch threshold, and the disc pressure trigger switch 1 is turned off, and the throttle is normally refueled to increase the vehicle speed.

The pressure trigger switch 1 is characterized by setting the switching threshold of the throttle force by the elastic coefficient of the elastic member. The switch threshold and the false pedal threshold are not necessarily equal, but must correspond, that is, when the accelerator pedal 16 is subjected to the power of the false threshold, the pressure trigger switch 1 must be in the switch threshold state.

Also included is a false pedal throttle correction device with a jog clutch:

The false pedal throttle correcting device with a jog clutch includes a pressure trigger switch 1, a pinch type micro clutch 2 and a brake cable 3, wherein: the jaw type micro-actuator 2 includes an active tooth that rotates coaxially. The inlay 4 and the driven jaw 5, the tooth surface of the active jaw 4 and the tooth surface of the driven jaw 5 face to a disengageable structure, the active jaw 4 has a toothless surface and a low voltage motor 6 The rotating shaft 7 is connected to form a structure in which the low-voltage motor 6 drives the active jaw 4 to rotate; the toothless surface of the driven jaw 5 is connected or contacted with the reciprocating valve shaft 9 of the low-pressure solenoid valve 8 to be driven by the low-pressure solenoid valve 8. The structure in which the driven jaw 5 moves axially along the center of rotation, that is, the reciprocating valve shaft 9 that becomes the low-pressure solenoid valve 8 can push the driven jaw 5 to engage with the active jaw 4; The toothed surface of the disc 4 and the opposing driven jaws 5 are provided with a separating spring 13 between the tooth surfaces; the outer periphery of the driven jaw 5 is provided with a concave ring 10 of the same plane, and the recess of the recessed ring 10 is embedded There are brake rope 3, the recess width of the recessed ring 10 and the brake The diameter of the trolley cord 3 is the same, or the recessed width of the recessed ring 10 is slightly larger than the diameter of the brake cable 3; the active jaw 4 and the driven jaw 5 are provided with a disc housing 11 and a disc housing 11 One end is fixedly connected to the outer casing of the low-voltage motor 6, and the other end of the dental disk casing 11 is fixedly connected to the outer casing of the low-pressure solenoid valve 8; the dental disk casing 11 is provided at a position corresponding to the recessed ring 10 of the driven jaw 5 The rope hole 12, the brake cable 3 end is fixedly connected in the recess ring 10, and the other end of the brake rope 3 passes through the guide rope hole 12; the pressure trigger switch 1 controls the low-voltage solenoid valve 8 and the low-voltage motor 6 connected in parallel.

The pressure trigger switch 1 controls the low voltage solenoid valve 8, the low voltage motor 6, and the trigger signal converter 35 connected in parallel. The false pedal throttle correcting device with the jog clutch is only suitable for correcting the accidental throttle action for the automobile. A device that produces a quick emergency brake. The emergency braking requirement is fast, and the displacement length of the existing brake machine can only be a short time, that is, the retractable length of the brake rope 3 is only about 10.0 cm. Therefore, the driven jaw 5 is only required to have a recessed ring 10, and only one ring of the brake cable 3 can be stuck in the recessed ring 10. The structure is such that the recessed width of the recessed ring 10 is the same as the diameter of the brake cable 3, or is recessed. The recessed width of the ring 10 is slightly larger than the diameter of the brake cable 3, so that the brake cable 3 cannot be moved casually in the recessed ring 10, or the movable position is small. The advantage of only one ring of the brake cable 3 in the recessed ring 10 is that the displacement length of the brake cable 3 is precise, that is, fretting and accurate. The precise position of the brake cable 3 being retracted into the recessed ring 10 is an accurate guarantee of the displacement length. The precise length and positional accuracy of the brake rope 3 movement are necessary for driving the brakes, and the conventional cable-type clutch electric hoist is not only complicated in structure, but also cannot be used to drive the brakes of the vehicle. The length is accurate and the position is precise.

The active jaw 4 and the driven jaw 5 in the clutch are driven by the gear meshing mode, and the snap driving method does not slip and is more reliable.

Preferably, the bottom of the recessed ring 10 with the inching throttle correcting device with the inching clutch is axially projected in the shape of a cam 15. The cam 15 has the characteristics that the linear velocity differs from the angular velocity when rotating. In the first rotating circumference of the starting, the cam 15 can output a faster linear velocity and a smaller pulling force to the brake cable 3, and then gradually slow down the linear velocity. And increase the pull. This is just right for the brake rope 3 to pull the car brake mechanism to achieve the braking process, the matching of the line speed and tension in the front and rear time. However, if the bottom 14 of the recessed ring 10 is a round wheel, the diameter of the round wheel should be larger to meet the quick start brake of the brake rope 3, and the diameter of the round wheel should be larger, so that the low-voltage motor 6 with a larger power can be used to meet the brake. The brake rope 3 required for the post action is pulled. Therefore, the cam 15 not only makes the brake cable 3 have a cushioning flexible braking effect on the output of the brake mechanism of the automobile, but also reduces the power and volume of the low-voltage motor 6, making it easier for the low-voltage motor 6 to find the optimum mounting position in the automobile. If the volume of the low-voltage motor 6 used is too large, it is possible that the mounting position cannot be found in some cars, so that the mis-trailing throttle correcting device with the jog clutch cannot be used for these cars.

When the active jaw 4 and the driven jaw 5 are in the separated state, the long axis of the cam 15 is located on the side close to the guide hole 12 of the socket housing 11; the brake cable 3 is at the bottom 14 of the recess ring 10 The connection point of 15, the line connecting the wire guide hole 12 of the ivory housing 11 is the tangential line of the cam 15. The cam 15 and the brake cable 3 are at the connection point of the bottom portion 14 of the cam ring 15 of the recessed ring 10, and the wire guide hole 11 of the dental disk housing 11 are in the position of the mating position, so as to ensure that the brake cable 3 is obtained. Flexible braking effect. With the position of the non-brake action state, when the active jaw 4 starts to drive the driven jaw 5 to perform the braking action, the cam 15 is larger than the long axis of the reference circle to have a faster line speed. Pulling the brake cable 3, when the active jaw 4 drives the driven jaw 5 to have rotated by about 180 degrees, the short shaft portion of the cam 15 pulls the brake cable 3 in such a manner that the linear speed is slowed down and the pulling force is greater. This is just suitable for the requirement that the brake rope 3 should be small in displacement and strong in pulling force in the late braking.

The maximum length of the brake cable 3 fitted into the recessed ring 10 is shorter than the circumference of the recessed ring 10. That is, the shallowest ring 10 is the shallowest The position can only be embedded in a layer of brake cable 3 in order to fully enlarge the cam 15 and reduce the volume of the error correction device. The rotation angle of the recessed ring 10 is within 360 degrees of rotation, so that it is possible to quickly obtain the length required for the brake cable 3 to be caught in the recessed ring 10 to generate a braking action.

The circumference of the recessed ring 10 is 5.0 - 15.0 cm. The length of the recessed ring 10 defined by the circumference is such that the rotation angle of the recessed ring 10 is within 360 degrees of rotation, so that the length at which the brake pulling rope 3 is quickly pulled to generate a braking effect can be achieved.

The "false pedal" as described in the present invention refers to the behavior of the driver erroneously stepping on the accelerator pedal when the brake pedal should be stepped on, that is, the wrong operation behavior of "the throttle brake".

The elastic member of the present invention comprises a compression spring, a disc elastic sheet, and further comprises a sponge, rubber, damper or the like having elasticity.

The invention has the advantages that the throttle sensor signal can be directly obtained, and the pressure sensor of the micro-electronic circuit is not needed to analyze the behavior of the pedal throttle with different weights to find the throttle behavior. The pressure-triggering switch of the present invention can be used to express the accelerator pedal displacement and the specific position at which the accelerator pedal is stressed, and then directly set the switching threshold of the elastic member to obtain the electric throttle switch electrical signal. By setting the switching threshold of the elastic element, instead of the pressure sensor of the microelectronic circuit, the signal analysis process of the electric signal is detected by the pressure signal analysis, that is, the continuous signal is replaced by the on and off methods. The method of credit analysis replaces complex electronic circuits with simple machinery, and replaces pressure sensors of microelectronic circuits with variable performance, poor stability, and unpredictable reliability with elastic components that are reliable and difficult to change automatically. . The invention is particularly suitable for use in automotive emergency signal acquisition requiring extremely high reliability and suddenness.

The motor can be directly driven by the electric signal of the accidental throttle switch issued by the accelerator pedal system of the present invention, and the reliability for correcting the misstep throttle behavior to be converted into the brake action is greatly improved. Moreover, the pressure trigger switch has a simple structure and low cost.

The in-jaw type micro-motion clutch drives the brake rope to not slip, and the reliability is good; the position of the brake rope in the concave ring of the clutch driven jaw is fixed, the position is accurate, and the displacement length of the brake rope is driven by the low-voltage motor. Accurate, can achieve the accuracy of the brake cord displacement length required to pull the existing brake machinery to achieve the purpose of braking. The jaw-mounted micro-motion clutch has a simple structure, small volume, low cost and good reliability.

The bottom of the recessed ring is in the shape of a cam, so that the brake cable attached to the bottom of the recessed ring can generate a buffered flexible braking effect when the brake mechanism of the vehicle is pulled, that is, when the brake is actuated by correcting the wrong throttle. When the brake rope is pulled, the brake mechanism of the automobile is pulled and the power is small, and the force is small, and the displacement is small and the power is large. This is a good fit for the need to correct the misstep of the throttle and perform the braking action.

The pressure trigger switch is connected to the trigger signal converter to convert the trigger signal of the pressure trigger switch into a control signal. If the control signal is a control signal for controlling the control of the throttle mechanism, the control model of the control signal is such that the control throttle mechanism causes the engine to immediately be in an idle state, so that the automobile engine loses the ability to drive the vehicle, but the steam The engine of the car maintains an idling state of operation and provides the power required by a safety system such as the brake system of the car. The trigger signal sent by the pressure trigger switch in the switch threshold state is divided into two paths, one for driving the false pedal throttle correction device with the jog clutch, starting the existing mechanism for emergency braking; the other is through the trigger signal converter The trigger signal of the pressure trigger switch is converted into a control signal for controlling the throttle mechanism, so that the throttle valve is in an optimal state for the emergency brake.

The pressure trigger switch is connected to the trigger signal converter to convert the trigger signal of the pressure trigger switch into a control signal. The control signal is a control signal for controlling the control of the throttle mechanism, and the control model of the control signal is such that the control throttle mechanism causes the engine to immediately be in an idle state, and the significance is: [1] causing the automobile engine to lose the driving motion of the automobile. The ability to avoid turning the accelerator pedal into an emergency brake, the engine is still driving the car, and the problem of emergency braking cannot be achieved. [2] Keeping the car engine at idle speed can provide the power required by the safety system such as the brake system of the car, so that the car is in normal working condition except for the loss of forward power. [3] Especially in the idle state, the brake pump has more power. At this time, it has more power to brake than the normal fueling state of the car. In the idle state, the brake can reduce the braking distance than the normal fueling state. [4] The engine of the car does not output power, and the engine has a damping effect on the wheel that is still rotating, that is, the engine has a damping effect on the rotating wheel. After actual measurement, there is an error correction emergency braking distance generated by the automobile of the present invention when the throttle is actuated by mistake, and the brake distance of the normal emergency brake is stopped immediately when the same vehicle is in the normal maximum fueling state. It should be about 10% shorter. Since the braking distance of the error-correcting emergency brake is about 10% shorter than the braking distance of the normal emergency brake, the effect of the vehicle of the present invention in avoiding a vehicle accident when the throttle is malfunctioning is more obvious.

When the brake rope 3 is required to have a displacement of about 10.0 cm, the circumference of the recessed ring 10 is only 5.0-15.0 cm. That is, the maximum length of the brake cable 3 fitted into the recessed ring 10 is shorter than the circumference of the recessed ring 10.
