Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for wirelessly starting an engine of an automobile, and particularly to a system for an in-vehicle telephone.

[Problems to be solved by conventional techniques and devices]

Normally, in order to start the engine of a car, the driver directly goes to the parking place of the car and operates the ignition device by key operation to start the car. However, when the outside temperature is low such as in winter, key operation is repeated many times, and it may not start until a considerable time has passed, and after such a time, the engine starts and after a while, the interior heating finally starts. During that time, the driver must feel cold in the cold car.

To address this, the inventor has filed a patent application (Japanese Patent Application No. 62-197777) for starting an automobile engine from the outside using an in-car telephone. Since the engine can be started, the engine may be left in an idling state, which promotes wasteful consumption of gasoline, and such leaving has a bad effect on the automobile itself.

[Means for Solving the Problems]

As a result of various studies in view of this, the present invention provides a starting device that eliminates waste of gasoline by stopping the engine after a predetermined time elapses with respect to the engine in an idling state by starting from the outside.

That is, the present invention sends an electric signal indicating that the vehicle is in the parking state, an electric signal indicating that the transmission is in the neutral state, an electric signal indicating that the ignition key is OFF, and an external telephone to the in-vehicle telephone transceiver device. A transmission / reception device control circuit which outputs when all the ignition signals are input, and an ignition starting circuit which outputs an ignition signal to the engine ignition device by the output signal of the control circuit are provided, and these circuits are provided by the engine by the ignition signal. When not ignited, it has a function to notify the presence or absence of engine start through an external telephone after outputting an ignition signal multiple times, and further has a timer that operates from the start of the engine start and a predetermined time preset in the timer. An engine stop device control circuit for operating the engine stop device after a lapse of time is provided,
Further, the circuit and the timer have a function of notifying whether or not the engine is started through the external telephone when an external telephone is called within a predetermined time, and an engine stop device when an engine stop signal is input from the external telephone within the predetermined time. The function to operate the engine, the function to operate the engine stop device by inputting a signal that the ignition key is not ON and a signal to release the parking state or a signal to release the neutral state of the transmission within a predetermined time, and the ignition within the predetermined time It has a function of stopping the timer by a signal indicating that the key is ON and canceling the control of the engine by the above circuit.

[Action]

The reason why the in-car telephone is used is because it is the easiest and surest means for wirelessly transmitting a signal to a car from a remote place. If the password is not a predetermined password, the transmitter / receiver for the in-car phone is used. If it is configured so that it cannot be input to the control circuit, malfunctions and mischief can be prevented.

Furthermore, the conditions for outputting the signal for activating the transmission / reception device control circuit and for activating the ignition device to the ignition starting circuit are that the vehicle is in the parking state, the transmission is in the neutral state, and the ignition key is OFF (or the key is OFF). Signal is not inserted) and the password signal for instructing ignition through the above-mentioned in-vehicle telephone is all input, and more thorough prevention of malfunctions,
This is to avoid the danger of the car running unmanned.

If the engine does not start with one output to the ignition device, the ignition starting circuit outputs the ignition signal a predetermined number of times because it does not always start with one ignition. It is better to carry out several times at intervals.

Furthermore, it is best to notify the person who is calling from the outside whether or not the engine is started as a result, because it is best to be finally confirmed by a human being. Should be done by voice or buzzer or chime.

Further, the engine is equipped with a timer that operates from the time the engine is started, and if a predetermined time is set in the timer in advance and no signal is input within that time, the engine stop device control circuit is operated after the time has elapsed and the engine is stopped. By stopping the operation, there is an advantage that waste of gasoline due to the idling state for a long time can be eliminated.

And it is more economical because the engine can be stopped immediately when the engine stop password is entered by the external telephone within the predetermined time set by the timer.In addition, the engine starts through the external telephone and the voice that the engine is idling is announced. Alternatively, it is very convenient because the buzzer will inform you.

Further, when the ignition key is turned on within a predetermined time by the timer, that is, when the driver enters the driving state, the operation of the timer is stopped, and the power supplied to the engine through the device of the present invention is the power of the device. Since the configuration is such that the route is switched from the control to the normal route from the ignition part, the operation which is no different from the conventional one is realized while traveling.

Further, it is extremely dangerous that the parking brake is released and the transmission is in a state other than the neutral state while the ignition key is not ON during such idling. Therefore, the engine is immediately stopped for safety.

〔Example〕

Next, the present invention will be described with reference to examples. As shown in FIG. 1, an in-vehicle telephone transmitting / receiving device (1) in an automobile, which is wirelessly connected to an external telephone, and an electronic control device (2) as described below were connected. The control device (2) receives the password signal from the transmitter / receiver device (1), the ON signal of the parking switch (3) that detects the operating state of the parking brake, and the gear sensor (4) that detects the neutral state of the transmission. A transmission / reception device control circuit (6) which outputs an output for engine ignition when an ON signal and an ignition sensor (5) OFF signal for detecting whether the ignition key is ON or OFF are all input, and the output Ignition start circuit control unit (7) operated by the, and an ignition start circuit (9) for igniting the engine by operating the ignition device (8) outside the electronic control unit (2) by the output signal of the unit (7) It operates by the engine start signal from the starter (10) that is outside the electronic control unit (2) and detects the start of the engine, and measures up to a preset predetermined time (here, 30 minutes) Timer (1

Then, the ignition starting circuit control unit (7) causes the ignition starting circuit (9) to perform three ignition operations at 5-second intervals based on a confirmation signal from the starting device (10) at the time of ignition, resulting in ignition / starting. If you don't do it, voice it to the external phone,
Also, when starting up, another voice or buzzer will be used.

Furthermore, if an external call is made to the electronic control unit (2) through the in-car telephone transmitter / receiver (1) within 30 minutes of the timer setting, the engine will start and will be idling, or the engine will stop for some reason. It is configured to notify whether or not it is present through an external telephone, and within 30 minutes, the ignition sensor (5) is not turned on and the parking switch (3) is turned off (released) or the gear sensor (4) is turned off (not neutral).
When a signal is input to the transmitter / receiver control circuit (6), the engine stop device control circuit (14) is immediately activated to stop the engine, and the signal indicating that the ignition sensor (5) is ON within 30 minutes is also a timer. When input to the control circuit (12), the system that automatically stops the operation of the timer (11) and the control of the engine through the electronic control unit (2) of the starter and switches to the normal driving control of the vehicle. Made in the car.
