In this case, Since the remote controller transmitter corresponding to the device to be operated is selected and remotely operated, not only is the usability not good, but also there is a problem that another remote controller transmitter is accidentally operated.

On the other hand, the distances that can be remotely controlled by these remote control devices vary. In other words, if the remote control device transmits and receives radio waves in a frequency band of a specific low power that is often used in the engine starting device, the distance that can be remotely controlled can be greatly extended (for example, several hundred meters). , Wireless operation from a distant place becomes possible. On the other hand, in a device that transmits and receives weak radio waves and infrared rays that are often used in a vehicle antitheft device and a door lock device, the remote controllable distance is as short as several meters to several tens of meters at most. Become. Then, when a plurality of remote control devices in which these are mixed are mounted, it is necessary to operate according to the transmission / reception distance corresponding to each device, which is also inconvenient in this respect. There are issues to be solved.

[0005]

The transmitter 1 includes a first switch 1a for starting the engine and a second switch 1b for operating another remote control device for performing anti-theft control described later.
When any of the switches is operated, a radio wave in a specific low power frequency band is transmitted. On the other hand, reference numeral 2 denotes an engine start control device. A control circuit 4 constituting the engine start control device 2 has a setting in which an engine start command and an engine stop command from the transmitter 1 are input via the receiving circuit 3. It has become.

[0007] A battery 5 is connected to the control circuit 4 via a terminal B of the engine start control device 2, and the power of the battery 5 is supplied to the control circuit 4 via a constant voltage circuit (not shown). It is provided to the CPU and is connected to the ACC relay 6, the IG relay 7, and the starter starting relay 8. The ACC relay 6 is wired externally through a terminal ACC, and is set so as to supply power to the ACC circuit of the vehicle by an output from the engine start control device 2 side.

The IG relay 7 supplies power to the ignition circuit of the vehicle through the terminal IG in the ON state. On the other hand, the starter starting relay 8 is connected to a starter motor 12 or a starter relay of a starter circuit, and is for driving the starter motor 12 to start the engine in an ON state thereof. It is connected to a starter motor 12 via an inhibitor switch 13. Incidentally, the inhibitor switch 13 is set to close based on the fact that the gear position is located at the parking position (P) or the neutral position (N). A gear position detection circuit 14 for detecting the position of the gear of the automatic transmission is connected between the starter start relay 8 and the terminal ST. The gear position detection circuit 14 is set to detect the gear position by utilizing the fact that the inhibitor switch 13 is closed and the ground state is established via the starter motor 12 when the inhibitor switch 13 is closed. It is set to output a signal to the control circuit 4 upon detecting that the gear position of the automatic transmission is parking (P) or neutral (N).

An engine start detection circuit 15 is connected to the wiring between the terminal B to which the battery 5 is connected and the control circuit 4. From the change between the battery voltage before starting (battery voltage drop) and the battery voltage after starting the engine (battery voltage rising), it is detected whether or not the engine is in the starting state, and it is determined that the engine is in the starting state. When this is done, an engine start signal is set to be output to the control circuit 4. Further, a voltage detection circuit 16 is connected between the IG relay 7 and the terminal IG, and an output side thereof is connected to the control circuit 4. Thus, the control circuit 4 is configured so that the voltage of the ignition circuit can be monitored by the voltage detection circuit 16.

In the present embodiment, as described above, a transmitter (second transmitting means) 18 constituting the anti-theft device 17 for preventing vehicle theft, and a transmission signal from the transmitter 18 are transmitted. An anti-theft device main body 19 that operates upon reception is disposed at an appropriate place in the vehicle. The transmitter 18 is connected to the control device 4 via a connector 20 provided in the engine start control device 2. ing. The transmitter 18
As described above, a weak radio wave is transmitted, and the receivable distance of the transmitted signal is set to several meters because of transmission and reception in the vehicle. When the first operation is performed from the second switch 1b of the transmitter 1 of the engine start control device, a signal for operating the anti-theft device is transmitted, and the start control circuit 4 receiving the signal transmits the signal to the transmitter 18. SE
When the T signal is output and the SET signal is input to the transmitter 18, the transmitter 18 transmits a signal for setting the anti-theft device main body 19 to a set state. To the set state, that is, the anti-theft control state. Next, the second switch 1 of the transmitter 1
When b is pressed again, an operation signal is output from the transmitter 1 and the control circuit 4 having received the signal outputs a RESET signal to the transmitter 18. When the RESET signal is input to the transmitter 18, the transmitter 1 18 transmits a signal for resetting the anti-theft device main body 19, and in response thereto, the anti-theft device main body 19 is controlled to be in a reset state, that is, a state in which the anti-theft control is reset.

FIG. 2 is a block circuit diagram of a transmitter 18 constituting the anti-theft device 17. Here, the transmitter 1
8 is a SET (set) of the control circuit 4 by the connector 20
A terminal is connected to a RESET (reset) terminal, and a signal is input from the control circuit 4 to the input circuit 21 via the connector 20. The signal input to the input circuit 21 is input to the determination circuit 22, in which the control circuit 4 outputs the SET signal and the RESET signal separately. In the first signal, the set state is set, and in the second signal, the reset state and the set-reset are alternately repeated. Therefore, the wiring from the control circuit 4 is unified into one before the input circuit 21. ing. In this case, the control circuit 4 and the transmitter 18 may be connected, or may be connected via switch means such as a transistor. A code signal generation circuit 23 is connected to the determination circuit 22, a transmission circuit 24 is connected to the code signal generation circuit 23, and an antenna 25 is connected to the transmission circuit 24. The code signal generation circuit 23 outputs an ID code and an operation command code to the transmission circuit 24 based on the signal
To the anti-theft device main body 19 via the.

The transmitter 18 has an input circuit 21, a determination circuit 22, a code signal generation circuit 23, a transmission circuit 24, and an antenna 25 in which a circuit having the same configuration as that of a transmitter of an existing anti-theft device is arranged on a printed circuit board. Control circuit 4
Is connected to the input circuit 21 so that a signal similar to the ON signal generated by the switch operation of the existing transmitter is generated. Therefore, the circuit configuration of the existing transmitter can be used as it is. Become. Then, the transmitter 18 can be connected to the engine start control device 2 by the connector 20, and can be easily connected to the engine start control device. Thus, the control device 4 and the transmitter 1
By making the connection with the input circuit 8 in the input circuit 21 of the transmitter 18, the control circuit 4 only needs to output a simple ON signal, the configuration of the control circuit 4 is simplified, and the connection of various types of transmitting means can be achieved. It becomes possible.

Next, the operation procedure of the engine start control 2 of the present invention will be described with reference to flowcharts shown in FIGS. First, in FIG. 3, the system is started and initialized. Then, it is determined whether there is a signal input from the receiving circuit 3 or not.
It is determined whether the signal is an engine start command by pressing the first operation switch 1a or an anti-theft command by pressing the operation switch 1b. In the former case, the engine start control is performed by the latter. In this case, the anti-theft control is executed as a subroutine.

FIG. 4 is a flowchart of the engine start control, which is executed when the above-described engine start command is transmitted. Here, the gear position of the automatic transmission is first determined by the gear position detection circuit 14. It is determined whether parking (P) or neutral (N). When it is determined that the engine can be started, that is, when the gear position is determined to be parking (P) or neutral (N), the control circuit 4 outputs to the ACC relay 6 and outputs the signal to the ACC relay 6.
Is turned on. Subsequent to the ON state of the ACC relay 6, the control circuit 4 outputs the signal to the IG relay 7 to turn it ON to supply power to the ignition circuit. Further, after the elapse of the first timer time, the control circuit 4 outputs to the starter starting relay 8 to turn on the starter motor 12
At the same time, the output to the ACC relay 6 is stopped and turned off to cut off the power to the accessory circuit. At this time, the engine start detection circuit 15 stores the voltage value of the battery 5 before the starter motor 12 is driven.

When the starter motor 12 is driven to start the engine, the generator of the vehicle rotates and the voltage of the battery 5 rises. When detecting that the predetermined voltage value has increased with respect to the voltage value of the battery 5 before driving, an engine start signal is output to the control circuit 4, and based on this, the control circuit 4 stops driving the starter motor 12. . In this state, the control circuit 4 outputs to the ACC relay 6 again to turn it on, supplies power to the accessory circuit, and furthermore, the control circuit 4 sets the operating state of the engine to a second timer set in advance. It is set to keep for a while. In this operating state of the engine, when an engine stop command is transmitted from the transmitter 1, the control circuit 4 is set to immediately stop the operating state of the engine.

On the other hand, the control circuit 4 does not detect the start of the engine even if the starter motor 12 is driven for a preset third timer time. That is, if the start of the engine fails, the control circuit 4 drives the starter motor 12. The engine is stopped, and after a predetermined time, the engine is restarted. Then, if the engine has failed to start the set number of times (three times in the present embodiment), it is determined that the engine is difficult to start due to some abnormality in the engine, and the subsequent start operation is stopped.

Next, a control procedure of the anti-theft device 17 of the present invention will be described with reference to flowcharts shown in FIGS. First, as shown in FIG. 5, when the driver transmits a signal for anti-theft control by pressing the second switch 1b of the transmitter 1, the control circuit 4 outputs the previous output to the transmitter 18 as described above. It is determined whether or not the signal is a SET signal (odd-numbered signal). If the signal is not a SET signal, a SET signal is output. If the signal is a SET signal, a RESET signal is output. In the embodiment, the same rising signal is set). On the other hand, the transmitter 18 also includes a control unit. In this case, when the anti-theft signal is input from the control circuit 4, the vehicle 18 assumes the anti-theft control posture of the vehicle, and as shown in FIG. When the input of the signal is the first time (odd number), a signal for setting to the set state is output, and the antitheft device main body 1 receiving the signal is received.
Reference numeral 9 designates an anti-theft control, and when an abnormality such as vibration of the vehicle or opening and closing of a door is detected by a separately provided sensor or the like, an alarm is issued to prevent the vehicle from being stolen. By the way, the alarm generation once generated is stopped, but in the present embodiment, it is set to stop when the anti-theft device main body 19 receives the RESET signal. Next, when the next (even-numbered) operation signal is input to the transmitter 18 in conjunction with pressing the second operation switch 1b of the transmitter 1 to release the set state of the anti-theft device 17, the transmitter 18 Sends a signal to the anti-theft device main body 19 to reset the theft monitoring, and the anti-theft device main body 19 receives the signal to release the anti-theft control. By the way,
In the present embodiment, the SET signal and the RESET signal are collectively input to the transmitter 18 without discrimination, and whether the signal is odd or even is determined to set and reset the anti-theft control. However, these SET signals, R
It goes without saying that the ESET signal can be separately input.

In the embodiment of the present invention configured as described above, while starting the engine and preventing theft are performed by remote control transmission, signal transmission for that purpose can be performed using one transmitter 1. As a result, unlike the case where the conventional transmitters are required separately, there is no need to operate different transmitters, and the signal transmission distance from the transmitter 1 is also the same, so that it must have been operated. However, it is possible to prevent a problem that a signal does not reach. In addition, since the anti-theft device 17 exemplified as the second remote control device is freely connected to the engine starting device 2 via the connector 20, for example, this type is commercially available. In this case, the engine starting device 2 side is used in common, so that not only the one with the anti-theft device 17 and the one without the anti-theft device 17 can be sold as a set, but also the user who purchased the latter installs the There is an advantage that it can be mounted without any problem when it is to be mounted.

It should be noted that the present invention is not limited to the above-described embodiment, and it is also possible to connect the input side of the transmitter of the door lock device and the control circuit instead of the anti-theft device. It is also possible to add a function for confirming that the operated device is operating.
