Abstract

<P>PROBLEM TO BE SOLVED: To provide an inexpensive alarm device capable of allowing a senior person or a driver not familiar with an automobile to safely drive the automobile by eliminating any improper step-on operation of a brake pedal and an accelerator pedal. <P>SOLUTION: A photoelectric sensor is arranged on the line connecting a conventional accelerator pedal of an automobile to a dashboard above the accelerator pedal. A caution is promoted to a driver by giving a sound alarm from a speaker provided on a center pillar close to an ear of the driver by signals from the sensor and on the shift position and the vehicle speed when a foot of the driver is placed on the accelerator pedal. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an alarm device for preventing an accidental depression of an accelerator pedal and a brake pedal of an automobile with an automatic transmission that is driven by a driver who is not familiar with elderly people or cars.

  Conventionally, as a measure to prevent accidental operation of an automobile with an automatic transmission, the parking position (P position), reverse position (R position), neutral position (N position), or drive position (D position) unless the brake is stepped on when stopped. However, this only prevents the car from popping out. The driver is not familiar with the elderly or the car, and the gear of the automatic transmission is in the R or D position, and there is no protection against misstepping caused by mistaking the accelerator pedal and brake pedal. is there.

  As mentioned above, most of the automobiles with automatic transmissions on the market today may not be noticed even if the driver who is unfamiliar with older cars or cars mistakes the brake pedal and accelerator pedal and makes a mistake There is. The present invention has been made in view of these points. The purpose of the present invention is to make it possible for an elderly person or a driver unfamiliar with a car to drive a vehicle inexpensively and safely by eliminating the mistake of stepping on a brake pedal and an accelerator pedal. Is to be able to do it.

  In order to achieve the above-mentioned object, a photoelectric sensor is arranged on a line connecting between an accelerator pedal of a conventional automobile and a dashboard on the accelerator pedal, and the accelerator is detected by the sensor, a shift position and a vehicle speed signal. When there is a driver's foot on the pedal, it is characterized by alerting the driver by sounding a voice from a speaker provided in the center pillar near the driver's ear.

  As described above, according to the present invention, when an elderly person or a driver unfamiliar with a car drives an automobile with an automatic transmission, the gear is in the R position or the D position, and the driver's foot is put on the accelerator pedal. The driver can easily recognize that his / her foot is on the accelerator pedal, and the driver can easily recognize that his / her foot is on the accelerator pedal. This is extremely effective for preventing pedal misoperation.

  Embodiments of the present invention will be described below in detail with reference to the drawings.

  1 and 2 relate to a first embodiment of the present invention, FIG. 1 is an external view in which a photoelectric sensor is mounted on a dashboard, and FIG. 2 shows a driver's foot on an accelerator pedal so that a light beam of the photoelectric sensor is emitted. It is an external view of the place where it was interrupted | blocked.

  As shown in FIG. 1, the photoelectric sensor 3 is attached to the range where the straight line of the light beam 4 connects the accelerator pedal 5 and the dashboard 2 on the upper part of the accelerator pedal 5, and the foot 8 of the driver 7 is If it is in the accelerator pedal 5, it detects that the light beam 4 of the photoelectric sensor 3 was interrupted on the way, and transmits a signal to an electronic control unit (ECU).

  FIG. 3 relates to the second embodiment of the present invention, and is an external view in which a speaker 9 that emits a warning sound is attached near the driver's ear of the center pillar 10 between the front door 11 and the rear door 12.

  FIG. 4 is a system diagram of information processing for generating a warning sound according to the third embodiment of the present invention.

  As shown in FIG. 4, the warning from the speaker is generated by processing the information on whether or not the light from the photoelectric sensor is blocked, the shift position of the automatic transmission, and the vehicle speed with an electronic control unit.

  From the speaker when the shift position of the automatic transmission is in the R position or D position, the vehicle speed is 20 km / h from the stop state, and the driver's foot is on the accelerator pedal, that is, the photoelectric sensor light is blocked This warning is set to be ON. By such information processing, when the vehicle speed becomes 20 km / h or more, there is no warning sound from the speaker, and the vehicle can be driven silently.

  The present invention can be used in the industrial field of manufacturing and selling automobiles and sensors.

  FIG. 1 is an external view in which a photoelectric sensor is mounted on a dashboard.   FIG. 2 is an external view of the accelerator pedal where the driver's foot is hung and the light beam of the photoelectric sensor is blocked.   FIG. 3 is an external view in which a speaker that emits a warning sound is attached near the ear of the driver of the center pillar.   FIG. 4 is a system diagram of information processing for generating a warning voice.
