JPS5939946A - Prevention against long idle running in vehicle - Google Patents

Abstract

PURPOSE:To prevent the occurrence of wasteful spending in fuel as well as of overdischarge in a battery, by detecting the fact that engine speed remains in an idling speed range for more than the specified time whereby a car is in a state of stoppage, while suspending the ignition of an engine. CONSTITUTION:An ignition suspension device 11 having a contact point 11a is installed in an engine's ignition circuit and the output of a timer 12-1 is connected to this suspension device via an amplifier 12-2. When a speed change gear is in neutral, a switch 8-1 is closed and when engine speed remains in a preset idling speed range, a comparator 7-2 transmits an output ''1'' to an AND gate 13 as well as when the timer 12-1 starts timing and the specified time elapses, a timer output comes to ''zero,'' opening the contact point 11a and cutting off the ignition circuit, thus the engine comes to a stop. When a clutch or a brake is operated, a switch 9-1 or 10-1 closes, resetting the timer 12-1. Therefore, even if a driver inadvertently parks his car for hours, the engine is automatically stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing long-term idling of a vehicle, such as a two-wheeled vehicle.

Conventionally, drivers often forget to stop the engine when parking, so if the vehicle is parked for a long period of time, fuel is wasted and the battery life is shortened due to over-discharge of the battery. Exists.

The present invention aims to eliminate such inconveniences, and includes a first detection means for detecting that the engine speed is in a preset idling speed range, and a first detection means for detecting that the transmission gear is in the neutral position. at least one of the sixth detection means for detecting that the clutch has been operated and the fourth detection means for detecting that the brake has been operated; a timing circuit that starts operation based on the detection output and operates an engine ignition stop means with the output when the operation time reaches the crotch time, and the timing circuit operates the third detection means and the fourth detection means. At least one detection output of the means d[
The feature is that the time is reset.

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

In the drawing, (1) is an ignition switch, and the ignition switch (11 is connected to a power source (2), a contact breaker (3) connected by a cam (not shown), and the other end of an ignition coil (4) which has an IK installed at one end. The spark plug 151 (61) is connected to the secondary side of the ignition coil (4).

Although the above circuit is not particularly different from the conventional one, according to the present invention, in order to stop the ignition operation by the ignition circuit in the case of long-term idle 4-turn, the engine speed is set in advance to idle operation. Detects that it is in the rotation speed region. a first detection means (7), a second detection means (8) for detecting that the transmission gear is in the neutral position, a third detection means (9) for detecting that the clutch has been operated, and a third detection means (9) for detecting that the clutch has been operated; a fourth detection means (10
), and the detection outputs of the front engine first detection means 17) and the second detection means (8), the full operation is started, and when the operation time reaches the set time, the engine ignition stop means 01 is activated. ) has a fully-operated clock circuit 02.

To explain this in more detail, in the drawing, first detection means (7) detects that the engine speed is in a preset idling speed range.
) is an engine rotational speed voltage-raw circuit (7 -1) and the voltage of the circuit (7-1) are input, and the engine speed Ii! 7.1 It consists of a comparison W (7-2) in which the output becomes a logical value "1" when the number is in the range of idling rotation speed, for example between 1000 rpm and 200 θ rpm, and becomes "mouth" in other regions. , the transmission gear is in neutral position f? The second detection means (8) for detecting that the state is in the neutral position is connected to a switch (8-1) which is closed when the state is in the neutral position, and a buffer (8-1) connected to one end of the switch (8-1).
-2), and the sixth detection means (9) for detecting that the clutch has been operated includes a switch (9-1) which is closed by the operation of the clutch lever and a buffer (9-1) connected to one end of the switch (9-1).
-2) The fourth detection means tilt, which detects whether the brake has been operated, has a switch (10-1f) that closes when the front brake lever is operated and a switch (10-1f) that closes when the rear brake lever is fully operated.
r) and the buffer (10, -2f
) (10-2b), the first detection means (7)
and the detection output of the second detection means (8) activates IJ1.
From 1 to 7, when the operating time reaches the set time, the clock circuit pupil which operates the engine ignition stop means (11) with its output is connected to each of the niJ comparator (7-2) and the buffer (8-2). A timer (12-1) whose output is input to an AND gate 031 k k and an amplifier (12-2) that amplifies its output.
It consists of.

The engine ignition stop means) is an ignition switch +1
1 and an ignition coil (4) via a contact (11a).

The IiJ timer (12-1) measures time when the output of the AND gate α~ is "1", and is "1" when the output of the AND gate α~ is "1".
When the output exceeds the set time, it becomes "0", and the power is turned on from off, or the output of AND gate 03 becomes "0", or
When any of the outputs of 2f)(10-2r) becomes "1" and this output is input through the OR game)(141), the timer is reset.

Next, its operation will be explained.

When the ignition switch (1) is closed and the engine is started by a starter (not shown) to start idling, if the transmission gear is in the neutral position, the switch (8-1) is closed and the buffer (8-2) is closed. [Output the month. On the other hand, if the engine speed is within the preset idling speed range, the comparator (7-2) outputs "1", so the AND gate 0311-i1 is output.

If none of the clutch lever, front brake lever, or rear brake lever is operated, the clock circuit α power timer (12) is activated when the engine speed reaches the preset idle speed range. When the operating time reaches the set time, the output changes from "1" to "0", and the switch α1) is deenergized through the amplifier (12-2) and its contact (11a) is turned off. When opened, the ignition coil (4) is cut off from the power source and the engine is stopped.

The driver operated the throttle valve and the engine speed became higher than the set range before the operating time of the timer (12-1) reached the set time. &, l: The driver operated the transmission gear. When the driver does this and opens the neutral switch (8-1), or when the driver operates the clutch lever and turns the switch (9-1) 11", the driver operates the front brake lever or rear brake lever. switch (10-
1f) or (10-1r) is closed, the timer (
12-1) becomes zero, and the contact (11a) of the switch Qll is closed until the set time elapses after the above conditions are satisfied again, and the ignition of the engine is not stopped.

As described above, according to the present invention, @ includes a first detection means for detecting that the engine speed is in a preset idling speed range, and a second detection means for detecting that the transmission gear is in the neutral position. , at least one of a sixth detection means for detecting that the clutch has been operated and a fourth detection means for detecting that the brake has been operated, and detection outputs of the first detection means and the second detection hand. a timing circuit that starts the operation and operates an ignition stop means of the engine with an output when the operation time reaches a set time;
The f-time circuit resets the clock by the detection output of at least one of the third detection means and the fourth detection means, so if the driver forgets to park the car and does not stop the engine, the parking time will be within the set time. When this point is reached, the idle operation is automatically stopped, which has the effect of preventing not only fuel wastage but also reduction in the life of the storage battery due to over-discharge.
