Description

[Detailed Description of the Invention] <Purpose of the Invention><Field of Industrial Application> The present invention relates to a device for warning of inappropriate operation of a clutch pedal in an automobile or the like.

<Background of the invention> For automobiles, tractors, and other industrial vehicles that are equipped with a manual clutch in the middle of the drive system, correct clutch operation is required when starting, shifting, etc. However, since beginners are not proficient in clutch operation, they focus excessively on clutch operation, and as a result, they always put their foot on the clutch pedal in preparation for the next clutch operation, but this method becomes habitual. is not necessarily desirable from the mechanical standpoint of the clutch.

For this reason, various devices have been proposed that issue a warning when the clutch pedal is slightly pressed. However, in reality, simply placing the foot on the clutch pedal does not immediately cause any inconvenience, and this method results in excessive warnings being issued, which is more of a nuisance for the driver.

<Technical matters that were attempted to be solved> The present invention was developed in view of this background, and is intended to solve a situation in which a problem actually occurs, that is, when the clutch is depressed slightly and the accelerator is depressed, the engine speed increases. This was an attempt to develop a new device that would issue a warning for the first time when an accident occurred.

《Structure of the invention》 〈Means for solving the problem〉 In other words, the clutch pedal foot rest warning device according to the present invention is designed to prevent the clutch pedal from being pressed slightly.
A clutch switch that is in the ON state and an accelerator clutch that is in the ON state when the vehicle is not idling are connected in series, and one end of these switches is connected to a power supply circuit from the battery, while the other end is equipped with a warning device. This device is characterized in that a timer is connected to the warning device and is provided in series with the warning device to supply power to the warning device after a certain period of time has elapsed, thereby achieving the above object.

<Example> The present invention will be specifically described below based on the illustrated example. Reference numeral 1 denotes a vehicle to which the present invention is applied, in which an accelerator pedal 2, a brake pedal 3, and a clutch pedal 4 are provided from the right side in a conventional manner below the front of the driver's seat. A clutch switch 5 is attached to the base of the clutch pedal 4, for example, which is turned on when the clutch pedal 4 is slightly pressed, and is normally off. , when accelerator pedal 2 is pressed
An accelerator switch 6 is provided which is in the ON state and is normally in the OFF state. Of course, such a switch may be provided at the base of the pedal or in the vicinity, or it may be provided at a position where switching is effected by the movement of a shift rod or wire that is substantially moved by the clutch pedal 4 or accelerator pedal 2. It may be. Next, the warning circuit 7 including the clutch switch 5 and accelerator switch 6 will be explained with reference to the wiring diagram shown in FIG. First, the clutch switch 5 and the accelerator switch 6 are connected in series within a warning circuit 7, and a timer 8 and a warning device 9 are further connected in series to one end thereof. This warning device 9 can be applied in various forms, including a warning with a buzzer-like sound, a lighting display with a lamp, a combination of these, or a warning with a synthesized sound. . On the other hand, a relay switch 11 is inserted in series on the battery 10 side of the warning circuit 7, and this switch is switched ON/OFF according to the operating state of the back clamp circuit 12. That is, the back clamp circuit 12 is provided in parallel with the warning circuit 7, and is a circuit that lights up, for example, a back lamp 14 when a back switch 13 provided in a transmission or the like is turned on. In this embodiment, when the back switch 13 is turned on, a relay 15 provided in parallel with the back clamp 14 is energized, and in accordance with this excitation, the relay switch 11 is turned off. This switches the relay switch 11, which is always on, to the off state.

The present invention has the configuration described above and operates as follows. First, under normal driving conditions, accelerator pedal 2 is depressed, so when driving, accelerator switch 6 is
However, if the foot is not placed on the clutch pedal 4, the clutch switch 5 is in the OFF state, so the warning circuit 7
Power is not supplied to the warning device 9 at , and therefore the warning device 9 does not operate. On the other hand, if the foot of the clutch pedal 4 is further placed on the accelerator pedal 2 while the accelerator pedal 2 is being depressed, the clutch switch 5 is turned on, and therefore power is supplied to the warning circuit 7. However, in this embodiment, the warning device 9 does not operate immediately in this state, but power is supplied to the warning device 9 only when power is first supplied to the timer 8 and this state is maintained for a certain period of time, and then the warning device 9 is supplied with power. Warnings are given by sound, lamps, etc. Incidentally, the reason why such a timer 8 is inserted is that the accelerator pedal 2 and clutch pedal 4 are activated even when starting normally or when changing gears.
Since there are cases where both pedals are used together, a warning should not be issued each time, but rather a warning should be issued only if both pedals are pressed simultaneously, which is a truly inappropriate state, for a certain period of time. It is something that exists. Furthermore, such an operating state is also performed when reversing. In this case, when the gear is switched to the reverse position, the reverse switch 13 is turned on, lighting up the reverse lamp 14, and also supplies power to the relay 15. The relay switch 11 is turned OFF by energizing the relay switch 11. As a result, the power supply circuit to the warning device 9 is turned off at the relay switch 11, and therefore, the warning device 9 is activated even if the accelerator pedal 2 and clutch pedal 4 are operated at the same time for a long time when reversing. It is configured so that it does not.

<<Effects of the invention>> As described above, according to the invention, a warning is issued only when a true inconvenience occurs when the foot is placed on the clutch pedal 4, and unnecessary warnings are issued. Since there are no warnings, there is no hassle when driving, and by following the warnings, you can learn to drive more correctly.
