Description

It relates to a reset device that prevents an accident due to an incorrect pedal depression between the brake pedal and the accelerator pedal.

A conventional automobile pedal device equipped with a mechanism related to brake operation and accelerator operation is attached between the accelerator lever and the accelerator arm via an outer cylinder rotatably arranged on the accelerator lever side with respect to the shaft core. It is equipped with an accelerator differential roller, and an accelerator adjustment mechanism consisting of a plurality of rod-shaped or bar-shaped accelerator control members attached to a receiving member attached to a protruding end on the accelerator arm side attached via a rotating shaft. ing. (Patent Document 1)

In the publicly known document of Patent Document 1, when the brake is suddenly applied at the accelerator operation position, if the brake pedal is instinctively depressed as it is, there is no time delay or mistake such as stepping from the accelerator to the brake. The erroneous operation is eliminated, and the brake operation is performed accurately and promptly.

Japanese Patent No. 5788187

By the way, the pedal device in Patent Document 1 is provided with an accelerator adjusting mechanism between the accelerator lever and the accelerator arm, and even if it is installed in place of the conventional pedal-type brake and accelerator, each vehicle model and driver's preference of different manufacturers The accelerator can be started and the acceleration can be easily adjusted accordingly.

However, at the accelerator operating position, when the accelerator pedal is depressed, the center of gravity is inevitably applied in the right lateral direction. If you try to apply the brakes suddenly, you must suddenly move the center of gravity to the lower left and depress the brake pedal. Although a stopper member is provided, there is a concern that it may slip sideways during sudden braking operation in an emergency.
In the current situation where braking operation by depressing the pedal is becoming a habit, training is required to get used to the above operation, and there is a problem that the foot gets tired from unfamiliar operation. Further, once the driver becomes accustomed to the accelerator operation, there is a problem that it becomes difficult to drive a conventional pedal-depressed vehicle.

When the throttle valve is opened and the accelerator pedal is further depressed, the rotor fully opens the throttle valve, and when the accelerator pedal is further depressed, the rotor rotates the groove to close the throttle valve and the accelerator pedal is released. When this is done, the slide plate is characterized in that it returns to the position before the accelerator pedal was depressed.

Further, the pedal misstep reset device according to the present invention includes an auxiliary brake pedal that is fixed to the lower end of the brake pedal and extends to just below the accelerator pedal, and the auxiliary brake pedal presses the brake pedal when the accelerator pedal is depressed. Push down.

That is, the itinerary diagram returns to the original state of FIG. 5 (A).

As described above, in the pedal misstep reset device, when the accelerator pedal 18 is depressed at once by mistakenly stepping on the pedal, the slide plate 5 suddenly descends, the rotor 6 stretches the throttle wire 10 to the maximum, and the throttle valve 11 is fully opened. It becomes a state. Further, when the rotor 6 rotates the corner of the position B and the throttle wire 10 is pulled back to the initial position, the throttle valve 11 closes, preventing a sudden start of the vehicle and avoiding a runaway accident.
The wrong pedal depression reset device does not start the car even if the wrong pedal is pressed, and the buzzer notifies the driver that the wrong pedal is pressed, so the driver does not panic and can step on the brake pedal 19 as usual. If the car stops reliably, the auxiliary brake pedal 20 will push down the brake pedal 19 integrated with the auxiliary brake pedal 20 to brake the brakes, and the car will stop reliably, preventing accidents. Can be prevented.

Therefore, the pedal misstep reset device is effective as a device for preventing accidents due to pedal missteps seen in elderly people and the like.
Further, if the pedal misstep reset device can be connected to the throttle valve and the accelerator pedal by using a lot or a wire, the throttle valve can be opened and closed mechanically even if it is electronic. The present invention can also be applied.
