Description

A device for preventing accidental depressing of accelerator pedal during emergency braking of automobile

technical field

The utility model relates to an electronic control device for preventing a driver from stepping on an accelerator pedal by mistake during emergency braking of an automobile.

Background technique

In the prior art, the driver's accidental stepping on the accelerator pedal during emergency braking has a "quick" nature, that is, the angular velocity of the accelerator pedal's instantaneous rotation is very large; The angular velocity is small; it indicates that there is a difference between the driver stepping on the accelerator pedal by mistake and stepping on the accelerator pedal during normal acceleration. Therefore, it is easy to step on the accelerator pedal by mistake during emergency braking, which will cause driving accidents and is very unsafe.

Contents of the invention

In order to solve the driving accidents caused by accidental depressing of the accelerator pedal during emergency braking, the utility model proposes a device for preventing accidental depressing of the accelerator pedal during emergency braking of an automobile.

The technical solution of the utility model is: a device for preventing accidental stepping on the accelerator pedal during emergency braking of a car, including an accelerator pedal, a rotation angle sensor, an anti-misstepping on the accelerator pedal control unit, a buzzer switch, a buzzer, and a low-voltage circuit of the ignition coil On-off switch, brake pedal driving motor, worm gear reducer, pull wire, brake pedal, characterized in that: the angle sensor is arranged on the support shaft of the accelerator pedal; the on-off switch is connected in series on the low-voltage circuit of the engine ignition coil; The brake pedal drive motor and worm gear reducer are connected to the anti-misstepping accelerator pedal control unit; the output shaft is connected to the lower end of the brake pedal arm through a pull wire; the voice alarm buzzer and buzzer switch are set on the instrument panel plate, and is controlled by the anti-mis-depressing accelerator pedal control unit.

On the premise of no need to change the driver's operating habits, the utility model utilizes the instinctive conditioned reflex to timely and effectively avoid the occurrence of driving accidents caused by the driver stepping on the brake pedal but mistakenly stepping on the accelerator pedal when dealing with an emergency , It can also save the precious time when the sole of the foot is shifted from the accelerator pedal to the brake pedal when dealing with an emergency, and reduce the rate of traffic accidents. The device follows conventional operation, has simple structure, low cost, and accurate braking, which can effectively avoid driving accidents caused by accidentally stepping on the accelerator pedal during emergency braking, and improve vehicle safety.

Fig. 1 is the structural representation of the utility model.

Among them, 1 is the accelerator pedal, 2 is the rotation angle sensor, 3 is the support shaft, 4 is the battery, 5 is the anti-misstepping accelerator pedal control unit, 6 is the buzzer switch, 7 is the buzzer, 8 is the ignition coil, 9 is Ignition coil low-voltage circuit on-off switch, 10 is a brake pedal drive motor, 11 is a worm gear reducer, 12 is a backguy, 13 is a support shaft, and 14 is a brake pedal.

Detailed ways

As shown in Figure 1, a device for preventing accidental stepping on the accelerator pedal during emergency braking of an automobile includes an accelerator pedal, a rotation angle sensor, an anti-misstepping on the accelerator pedal control unit, a buzzer switch, a buzzer, and an ignition coil low-voltage circuit on-off Switch, brake pedal drive motor, worm gear reducer, pull wire, brake pedal. The rotation angle sensor 2 is installed on the support shaft 3 of the accelerator pedal 1, and the instantaneous rotation angular velocity signal of the accelerator pedal is detected by the rotation angle sensor, and the signal is transmitted to the anti-misstepping accelerator pedal control unit 5; on the low-voltage circuit of the engine ignition coil 8 The series on-off switch 9 is controlled by the anti-acceleration pedal control unit 5 to cut off the primary circuit of the engine ignition coil; the brake pedal driving motor 10 and the worm gear reducer 11 are controlled by the anti-acceleration pedal control unit 5, Its output shaft links to each other with the lower end of brake pedal 14 arms through backguy 12, realizes backguy to shrink quickly by the rotation of worm gear shaft, to drive brake pedal 14 to move down and brake; Buzzer switch 6, buzzer switch 6 is disconnected under normal circumstances, is controlled by anti-misstepping on accelerator pedal control unit 5. When the car emergency brake driver accidentally steps on the accelerator pedal 1, the instantaneous rotational angular velocity of the accelerator pedal around the shaft is detected by the accelerator pedal angle sensor 2 and is transmitted to the anti-misstepping on the accelerator pedal control unit 5, and the anti-misstepping on the accelerator pedal control unit 5 Drive the ignition coil low-voltage circuit switch 9 off, cut off the primary circuit of the engine ignition coil 8, force the engine to stop, and at the same time turn on the buzzer switch 6, and the buzzer 7 will issue a voice prompt for misstepping, and can control the brake pedal to drive When the motor 10 works, the worm gear shaft of the worm gear reducer 11 drives the backguy 12 to shrink rapidly to realize brake braking.

On the premise of no need to change the driver's operating habits, the utility model utilizes the instinctive conditioned reflex to timely and effectively avoid the occurrence of driving accidents caused by the driver stepping on the brake pedal but mistakenly stepping on the accelerator pedal when dealing with an emergency , It can also save the precious time when the sole of the foot is shifted from the accelerator pedal to the brake pedal when dealing with an emergency, and reduce the rate of traffic accidents. The device follows conventional operation, has simple structure, low cost, and accurate braking, which can effectively avoid driving accidents caused by accidentally stepping on the accelerator pedal during emergency braking, and improve vehicle safety.
