Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to fuel conservation in motor vehicles, and more particularly to a device which makes it possible to eliminate unnecessary idling.

Conventionally, starting and stopping an automobile engine has generally been done using an ignition key installed on the instrument panel or near the steering wheel, but in this case, the driver is required to lean forward from the seat. As a result, the ignition key could not be operated with optimal movement of the steering handle and gear shift lever.
Furthermore, since the same key is operated with the right hand when starting the car, it is not possible to return the right hand to the steering wheel after starting the engine and do it almost at the same time as starting the engine. Therefore, when the car is stopped for a relatively long time, such as at a train stop, at an intersection, or on a road with heavy traffic, the driver must stop the engine, which causes unnecessary idling, which reduces fuel consumption. Because the fuel is wasted, it causes exhaust gas pollution and noise pollution near intersections and traffic congestion.

The present invention solves the above-mentioned drawbacks, and while maintaining normal driving operation, when the operating lever such as the gear shift lever is not operated (
In the neutral position of the lever, the engine stops rotating, and the engine is started when the lever is operated as described above.
Although the above-mentioned method has various excellent features,
On the other hand, when the number of starts and stops in a city center etc. is large, the inrush current at the engine start is large, so
The battery may become over-discharged.

In order to eliminate these problems, the present invention further constantly monitors the state of charge of the battery, and when the battery capacity is consumed below the rated capacity, the operation of the above-mentioned structure is temporarily suspended, and the conventional operating method is The objective is to provide an engine operating device that automatically switches.

Next, the configuration and operation of an embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is an electrical circuit diagram of a battery charge state monitoring section, in which a comparison is made between the battery voltage and a reference voltage.

In the figure, the base of the transistor Tro is connected to a battery to be compared, its emitter is connected to a reference voltage circuit ES, and its collector is connected to a power supply via a resistor.

In addition, the collector of the transistor TrC is connected to the base of the next-stage PNP transistor Trl, and the collector of the same transistor is connected to the base of the next-stage transistor Tr2. It is connected to the base of the preceding transistor Trl via a resistor.

Further, the collector of the transistor Tr2 is connected to the base of the next stage NPN type transistor Tr3, and the outside of the collector is connected to the power source via the coil of the relay RY.

Furthermore, the normally open contact of the relay RY is connected to the external terminal T2. Further, the peripheral circuit including the integrated circuit IC in the figure is a power supply stabilizing circuit.

A battery monitoring section constructed of the above-mentioned members is shown by 1 in FIG. Next, the configuration of the on/off circuit for the engine ignition system by operating the gear shift lever will be explained.

Figures 2, 3, and 4 show the position of the gear shift lever and the mounting relationship of each limit switch, and Figures 5, 6, and 7 show the position of the shift lever and the mounting relationship of each limit switch.
The figures each show the contact configuration of each limit switch with respect to the position of the shift lever. Sunahachi “Figures 2 and 3
In FIG. 4, an actuator ring 2 is fixed to the shift lever 1, and limit switches PS1 and PS2 are respectively installed opposite the yielding ring in the neutral position.

In addition, in the figure, "The broken line indicates the position of the shift lever, F1, F
2, F3. F4 "is 1st far, 2nd gear, 3rd gear, 4th gear respectively.
8 corresponds to "far" and "R" corresponds to "backward," and "2" in FIG. 8 indicates the part formed by the above-mentioned structural members.

Next, the effect of the above-mentioned Yokosei will be explained.

As shown in FIG. 1, a reference voltage is set at the emitter of the transistor Tro, and when the input voltage (battery voltage) is lower than the reference voltage ES plus the base-emitter voltage Veb of the transistor Tro, the transistors Tro, Trl
is off, Tr2 is on, and therefore Tr3 is conductive,
Relay RY operates, its contacts turn on, and terminal T
2 is also turned on.

When the input voltage is equal to or higher than the rated voltage, Tro and Trl are turned on, and therefore the conduction of Tr3 is released and the terminal T2 is turned off. Next, the opening/closing operation of the ignition system by the gear shift lever will be explained.

In other words, in FIGS. 2, 3, and 4, FIG. 2 shows a state in which the shift lever 1 is located at the neutral position,
In this case, the limit switches PS1 and PS2 are pushed by the actuator ring 2, and as shown in FIG.
, PS2 are both turned on, and accordingly the terminal T is also turned on.

However, both the yield mitt switch PS1 and the mitt switch 2 are of long stroke type and are normally open contacts.

Figure 3 shows when the gear shift lever is located at F3 3rd far.
The limit switch PSI' is kept in the on state while being further pressed due to the actuator ring 2.

On the other hand, the limit switch PS2 is released from the pressure of the actuator ring, and its contact is turned off. Therefore, as shown in FIG. 6, the terminal TI is turned off. Further, FIG. 4 shows a case where the shift lever is in the FI first feed position, and the limit switches PS1 and PS2 are both out of the actuator ring 2, and the contacts of both switches are off.

Therefore, the terminal TI is turned off as shown in FIG.
An example of an embodiment using the two components described above will be described with reference to FIG. 8.

First, the normal state (the battery is charged as specified)
To explain how to drive the engine, put the gear shift lever in the neutral position and turn on the key switch on the instrument panel, then the accessory circuit 2
3 becomes operational, the engine also becomes ready to start, but the engine is not started yet.

In this state, when the shift lever is shifted to the first speed side, the terminal TI is turned off as described above, and the normally closed contact RY1b of the relay RYI is turned on as shown in FIG. 9, and the output terminal T3 is also turned on, the magnet switch 20 is turned on, and the engine is started by the rotation of the starting motor 21 and the start of sparking of each plug 12 to 15 by the ignition coil 29.

The above is normal operation, but if the battery is discharged below the rated voltage (overused), the output terminal T2 of the battery monitoring section 2 will be turned on, as described above and as shown in the figure. As is clear from the wiring connection, the ignition system is connected as is in conventional cars, so it is operated in exactly the same way as conventional cars.

Note that 31a, 31a2, 32 shown in Figure 8 of the drawing
The action of a is as follows.

The switch 31a is used to operate the manual ignition key in one step, and is normally used to open and close accessory circuits in the vehicle. In addition, when the speed of the car decreases, the ignition circuit automatically turns off by the action of 31a and 31a2, but if necessary, the circuit can be manually turned off to prevent it from turning off. used. 3
2a is a normal ignition start switch.

Then, when the car is driven and the battery voltage is charged by the dynamo to a level higher than the rated voltage, the output terminal T2 of the battery monitoring section is turned off and the car is driven according to the method of the present invention.

Furthermore, when the vehicle is stopped, if the gear shift lever is placed in the neutral position, the terminal T3 is turned off and the engine rotation stops.

Note that the above description describes one embodiment of the present invention, and does not limit the vehicle type or other aspects.

As described above, the present invention does not impede the driving or engine performance in any way, but rather improves the safety of the vehicle, reduces fuel consumption, and reduces exhaust gas pollution and other hazards. It is effective in preventing sound pollution. Additionally, the engine's automatic operation function is temporarily reserved depending on the state of charge of the battery. There are effects that don't need to be done.
