As can be seen from the above, the fixed transmission shaft 8 and the brake pedal 6 are driven in the same direction, and in order to achieve synchronous and same-direction driving of the accelerator pedal 1 and the brake pedal 6, it is necessary to ensure that the moving gear 77 and the accelerator gear 12 form the same-direction driving when engaged, and based on this, the specific structure of the moving gear 77 can be set as follows: the movable gear 77 comprises a mounting plate (not shown in the figure) which is in running fit with the electromagnetic ring 78, and two mutually meshed pinions (not shown in the figure) which are arranged on the mounting plate, so that when the movable gear 77 is meshed with the accelerator gear 12, mutual meshing of three gears is formed, and it is ensured that a first gear and a third gear in the three gears form same-direction driving, wherein the first gear is the accelerator gear 12, and the third gear drives the movable transmission shaft 7 to rotate, so that the same-direction transmission among the accelerator pedal 1, the movable transmission shaft 7, the fixed transmission shaft 8 and the brake pedal 6 is effectively realized. In addition, when setting the transmission ratios of the three gears, at least the transmission ratio of the first gear and the third gear should be set to 1:1, so as to ensure synchronous transmission of the accelerator pedal 1 and the brake pedal 6.
Further, the structure for engaging or disengaging the driving moving gear 77 with or from the throttle gear 12 includes:

and a second return spring 79 connected to a side of the electromagnet ring 78 away from the moving gear 77, wherein when the moving gear 77 moves toward the throttle gear 12, the second return spring 79 performs a movement return force accumulation.

From the above, the invention further provides a method for remedying the mistaken stepping of the accelerator pedal of the automobile, which is specifically executed based on the remedying device disclosed above, and the remedying method comprises the following steps:
s1, detecting the current opening degree of an accelerator pedal 1 through an accelerator pedal position sensor 2; if the opening degree is smaller than the threshold value, normally driving; if the opening degree is larger than the threshold value, the process goes to step S2;
specifically, the opening threshold may be set to 80% to 90% of the opening of the accelerator pedal 1, so as to ensure the accuracy of the entire apparatus and method for identifying the false stepping.
Specifically, as shown in fig. 1 and fig. 2, when the accelerator pedal 1 is stepped on, the accelerator pedal 1 drives the accelerator rotating shaft 11 to rotate clockwise, the accelerator rotating shaft 11 drives the movable transmission shaft 7 to rotate counterclockwise based on the engagement between the accelerator gear 12 and the fixed gear 72, the movable transmission shaft 7 drives the connecting sleeve 74 to rotate counterclockwise through the cooperation between the sliding groove 73 and the slider, and the connecting sleeve 74 drives the volute spiral spring 76 to deform during the counterclockwise rotation, so as to generate the force accumulation effect. In this process, since the first engaging teeth 75 and the second engaging teeth 83 are in a separated state, the brake pedal 6 and the corresponding structure thereof are not affected.
S2, setting an output signal of the accelerator pedal 1 as an initial position signal (the operation is to enable the automobile to recover to an idle state so as to prevent the automobile from continuously accelerating) through the control module 5, and controlling the electromagnetic coil 81 to be electrified and started to realize meshing linkage of the movable transmission shaft 7 and the fixed transmission shaft 8; after meshing, under the reset of the scroll spring 76 and the connecting sleeve 74, the brake pedal 6 is driven to be rapidly braked to a position with an opening corresponding to the accelerator pedal 1;
specifically, as shown in fig. 7, after the electromagnetic coil 81 is energized, the electromagnetic coil 81 generates an attractive force to the movable transmission shaft 7, so as to drive the movable transmission shaft 7 to approach the fixed transmission shaft 8, the first engaging teeth 75 and the second engaging teeth 83 are gradually engaged in advance during the approaching movement, and the separation of the accelerator gear 12 from the fixed gear 72 is also realized during the engaging process, after the accelerator gear 12 is completely separated from the fixed gear 72, the connecting sleeve 74 is driven by the spiral spring 76 to rotate clockwise to reset, and the rotation of the connecting sleeve 74 drives the movable transmission shaft 7 to rotate clockwise (at this time, the smooth rotation of the movable transmission shaft 7 can be ensured due to the separation of the accelerator gear 12 from the fixed gear 72), and the movable transmission shaft 7 drives the fixed transmission shaft 8 to rotate clockwise by the engagement of the first engaging teeth 75 and the second engaging teeth 83, when the fixed transmission shaft 8 rotates clockwise, the braking rotating shaft 61 is driven to rotate clockwise by the cooperation of the fixed transmission wheel 82 and the braking transmission wheel 62, and the braking pedal 6 is driven to rotate clockwise.
In addition, regarding the rotation process of the brake pedal 6, taking the stepping opening degree of the accelerator pedal 1 as an example, the rotation process of the accelerator pedal 1 is 85% clockwise, the corresponding movable transmission shaft 7 is rotated counterclockwise for 85% rotation process in step S1, and the 85% rotation process is similarly reset in the power accumulation reset of step S2, so that the rotation process of the brake pedal 6 is the same as the rotation process of the accelerator pedal 1, and the same degree of braking effect of stepping on the brake pedal 6 can be achieved by stepping on the accelerator pedal 1.
S3, detecting the current opening degree of the brake pedal 6 through a brake pedal position sensor 9; when the opening degree value of the brake pedal 6 is fixed, the process proceeds to step S4; this step is indicated as performing further linkage after the power storage braking described in step S2 is completed;
s4, controlling the electromagnetic ring 78 to be electrified and started through the control module 5 so as to realize synchronous linkage of the accelerator pedal 1 and the brake pedal 6 through meshing of the movable gear 77 and the accelerator gear 12;
specifically, as shown in fig. 8, after the electromagnetic ring 78 is energized and started, an attractive force is generated between the electromagnetic ring and the electromagnetic coil 81 (as can be seen from the above process, the electromagnetic coil 81 is still in an energized state), so that the moving gear 77 is driven to move toward the accelerator gear 12, and thus the accelerator gear 12 is engaged with the moving gear 77, and in the process, the second return spring 79 is deformed to accumulate the force for the return of the following moving gear 77; in the process, the first meshing tooth 75 is meshed with the second meshing tooth 83, so that the movable transmission shaft 7 and the fixed transmission shaft 8 are formed into a whole, the accelerator pedal 1 can be driven to drive the brake pedal 6 to be driven synchronously when being further driven, expected operation can be continuously completed without replacing the pedal after a driver steps on the accelerator pedal 1 by mistake, and the mistaken-stepping remediation mode is simpler and more convenient. And the synchronous and equidirectional driving enables the accelerator pedal 1 to completely replace the brake pedal 6, thereby effectively meeting the daily operation habits of drivers, such as treading hard and increasing the brake.
In summary, the control module 5 can be further provided with an alarm unit for performing different types of alarms at different stages, in addition to executing corresponding control actions; for example, when a false tread is detected, a continuous alarm of "dripping" is performed; upon completion of the brake remediation, an "remedied" alarm is made; when the accelerator pedal 1 and the brake pedal 6 are synchronously linked, an alarm of "linked" is issued. In addition, the arrangement of the patent (CN107031396B) can also remind the opening degree of the accelerator pedal 1, so that the problem that the vehicle is identified as being treaded by mistake in the acceleration process is avoided, and the identification accuracy of the whole device and the method is improved.
