JPH06340231A - Automobile having mis-stepping preventive device for acceleration pedal - Google Patents

Abstract

PURPOSE:To prevent a mis-stepping accident by releasing fixing of a fixed acceleration pedal when a pressure sensitive switch is operated while putting the seat of the sensitive switch operated by the pressure of a heel onto the lower side floor of the accelerating pedal. CONSTITUTION:The seat 7 of a sensitive switch is fixed to the lower side floor of an acceleration pedal by a magic tape, etc., voltage is applied according to the rating of the sensitive switch, and feeble current due to ON or OFF is amplified in a semiconductor element circuit 6 to operate a solenoid 5. An accelerator is locked by the spring of the solenoid 5 because stepping the acceleration pedal without putting a heel on a floor means the error of brake operation. By the operation of the solenoid, the hole of a fitting 3 attached by the idea of an acceleration pedal connecting rod is caught by a pin, and the solenoid is operated when the sensitive switch is turned ON to release the pin from the hole. When the heel is put on the floor, the accelerator can be operated freely.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to prevent an erroneous pedal operation by using an electric mechanism in a vehicle incorporating an automatic transmission.

2. Description of the Related Art There is a shift lock mechanism with a key / interlock. This meant that the shift lever could not be moved from the parking position unless the brake was pressed. The mechanism does not work from the neutral position. Misoperations are still likely to occur.

DISCLOSURE OF THE INVENTION Regardless of the position of the shift lever, the accelerator pedal is prevented from operating in a braking manner.

[Means for Solving the Problems] When the difference between the brake and accelerator pedals is examined, the heels of the brake pedals are raised and the heels of the accelerator pedals are attached to the floor to provide stability in the degree of pedaling. Therefore, if the difference is detected by the pressure sensitive switch sheet 7 and the accelerator pedal is depressed without the heel being attached to the floor, it means that the brake operation is incorrect and the accelerator is locked by the spring of the solenoid 5. However, when he feels the pressure on the heel, the pressure-sensitive switch is turned on and the connected solenoid works to unlock the accelerator so that it can be operated freely.

[Embodiment] A palm-sized pressure-sensitive switch sheet 7 is fixed to the floor below the accelerator pedal with a velcro or the like, and a voltage is applied according to the rating of the pressure-sensitive switch to turn it on and off.
The weak current due to is amplified by the semiconductor element circuit 6 and the solenoid 5 is activated. The function of the solenoid is to catch the hole of the metal fitting 3 attached by the invention of the ascer pedal connecting rod with the pin, and when the pressure sensitive switch is ON, the solenoid operates and the pin is pulled out from the hole. The accelerator can be operated freely when the heel is on the floor. However, if the heel is raised during the operation of the accelerator, the pin will return due to the spring, which will obstruct the movement of the accelerator. To prevent this, the flat surface that is aligned with the hole of the metal fitting that is attached to the assel pedal connecting rod by the device is a flat metal surface so that the pin does not return except the position of the pin hole when the accelerator is not operated. . In addition, even if an electrical failure occurs in this circuit, the accelerator is not locked while it is being stepped on, so it is safe.

[Effects of the Invention] It is possible to prevent a serious accident such as a pedaling accident.
