Description

Auxiliary ignition device for starting off while driving

The present invention relates to an auxiliary ignition device for preparing for starting off of a vehicle. That is, the present invention relates to an auxiliary ignition device that allows ignition to be performed immediately by an emergency switch mounted on an in-panel when the ignition is turned off due to a driver's mistake or the like while the vehicle is running.

One of the essential devices for driving a car is the ignition. This ignition device is a device that ignites and combusts a compressed mixer in an combustion chamber at an appropriate time with an electric flame, and a general ignition system is composed of a battery (BAT), an ignition switch (IG-SW), and an ignition coil as shown in FIG. Battery ignition type, magnetic ignition type, and semiconductor ignition device composed of (IG-CO), Distributor, and the like.

Here, when the battery ignition type ignition device is operated, when the ignition switch (IG-SW) is turned on using a car key, the current of the battery (BAT) or the generator passes through the primary side of the ignition coil (IG-CO) and the contact point of the interrupter. Flows into.

At this time, if the contact is closed, current is grounded through the contact to generate magnetic lines on the primary side of the ignition coil. At this time, when the engine rotates and the contact opens, the current flowing to the primary side is cut off, and a high voltage (10,000 to 30,000 V) is generated on the secondary side due to the rapid decrease in magnetic lines.

This high voltage is distributed to each spark plug as the rotor rotor rotates through a high-voltage cable, and sparks ignite between the electrodes of the plug to ignite the mixer in the combustion chamber.

In addition, the semiconductor ignition device uses a variety of semiconductor elements of which the computer type ignition device is shown in FIG.

That is, the device consists of a battery (BAT), an ignition switch (IG-SW), an ignition coil (IG-CO), an electronic control unit (ECU), a distributor, an injector, and the like. After detecting (speed, load, temperature) and inputting it to the electronic control unit (ECU), the electronic control unit (ECU) calculates the ignition timing and sends a signal to cut off the primary current to the distributor to generate high voltage secondary current. Is known as the latest type of ignition.

However, these ignition devices are not equipped with a separate emergency ignition safety device for starting off while driving, so if the driver needs to drive carefully, if the ignition is turned off by mistake, operate the ignition switch again to operate the ignition switch. There was only one way to give.

However, the ignition structure as listed above is not equipped with the emergency ignition safety device, so if the engine starts to shut down due to the driver's mistake or mischief of the passenger while driving, the driver should restart the vehicle by following the car key at the bottom of the steering wheel. If you're embarrassed and don't start the engine right away, you're in danger of causing a big safety accident. In particular, in the case of an electronically controlled vehicle, the control operation of the electronic control unit (ECU) is stopped when the engine is turned off. Therefore, the steering wheel is locked and the hydraulic system is also stopped. Therefore, a large accident may occur in the case of a curve road or sudden accident. It is not there.

Therefore, in the present invention, in view of the deficiencies of the conventional ignition device configuration as described above, the emergency ignition means in parallel with the ignition switch is installed between the battery and the ignition coil, the start is turned off by the driver's mistake. In this case, it is an object of the present invention to provide an auxiliary ignition device in preparation for starting off during driving in which the engine can be immediately started by the emergency ignition means.

The auxiliary ignition device of the present invention for achieving the above object is a battery (BAT) mounted on a vehicle to supply power to various electric devices, ignition switch (IG-SW) 'on / off' by the operation of the car key Ignition coil (IG-CO) which consists of 1st and 2nd coils to generate high voltage, electronic control unit (ECU) which receives signals from various sensors and outputs control signals, ignition of automobile In the apparatus, the emergency ignition means (1) is connected between the battery (BAT) and the ignition coil (IG-CO) in parallel with the ignition switch (IG-SW), so that the emergency ignition when the engine start is turned off while driving. It is characterized in that the safe operation can be carried out by allowing the engine to be immediately started using the means (1).

Therefore, according to the present invention, as a result, it is possible to achieve an effect of preventing the engine starting off, thereby providing a safe driving effect of preventing a large accident.

(Example)

Hereinafter, described in detail based on the non-limiting embodiment to which the auxiliary ignition apparatus of the present invention is attached.

3 is an exemplary view of the present invention applied to a computer type ignition device.

As shown in the figure, the auxiliary ignition apparatus according to the present invention comprises an emergency ignition means (1) installed between the battery (BAT) and the ignition coil (IG-CO) constituting a conventional ignition apparatus. Ignition means (1) is installed in parallel with the ignition switch (IG-SW), the configuration is the emergency push switch (E-SW) and the speed-sensitive switch (S-SW) and the reverse flow prevention diode (D) connected in series with each other The input shaft of the emergency push switch E-SW is connected to the battery BAT, and the output side (cathode) of the diode D is connected to the ignition coil IG-CO.

The emergency push switch (E-SW) is installed in the panel so that the driver is very easy to operate, the speed-sensitive switch (S-SW) connected in series is 'on / off' operation according to the driving speed of the vehicle The diode D, which is a switch and is connected in series with the speed sensitive switch S-SW, is a semiconductor device that serves to prevent the power from flowing back toward the speed sensitive switch S-SW.

Referring to the operation of the present invention exhibiting such a configuration, first, when the driver starts using the car key to drive the vehicle, the ignition is activated according to the engine state by the control operation of the electronic control unit (ECU) as usual. The engine starts and the low speed or high speed travel is performed according to the operation of the accelerator unit.

However, when the engine is turned off due to the driver's own mistake (over clutch operation, high start) or mischief of the passenger (car key operation) while driving, the driver is embarrassed because the emergency ignition means 1 is provided separately in the present invention. If the emergency push switch (E-SW) installed in the panel is simply pressed, the power of the battery (BAT) will be switched to the emergency push switch (E-SW) → speed sensitive switch (S-SW; State) → It is applied to the ignition coil (IG-CO) through the diode (D), so the engine is started immediately, so that the vehicle can be safely operated.

On the other hand, the emergency push switch (E-SW) is operated to be opposite to the ignition switch (IG-SW), that is, the emergency push switch (E-SW) is turned off (ON) in the ON state of the ignition switch (IG-SW). OFF, and when the interlock system is configured such that the emergency push switch (E-SW) is turned on in the OFF state of the ignition switch (IG-SW), the engine can be automatically prevented from being turned off.

Thus, according to the present invention, in the present invention, the emergency ignition means 1 is provided in parallel with the ignition switch IG-SW in the construction of the ignition device. By operating the emergency ignition means (1) to immediately restart the engine is to prevent large accidents in advance, and further ensure the safe operation of the operation.

What has been described above is only one embodiment for explaining the auxiliary ignition apparatus according to the present invention, the present invention is not limited to the above embodiment, without departing from the gist of the invention claimed in the following claims Various modifications can be made by those skilled in the art to which the present invention pertains.
