The automatic light drive control device and the wireless engine starting device will be described below. First, the outline of the automatic light drive control device will be described with reference to FIG. That is, the automatic lighting headlight device, which is the autolight drive control device shown in FIG. 4, has an optical sensor 1 that detects external light, compares the detection output of the optical sensor with a predetermined reference value, and A level change detection circuit 2 for determining whether it is daytime, evening or nighttime, and outputting three kinds of determination signals corresponding to the respective levels, the level change detection circuit 2
A signal for instructing which of the headlight 7 and the tail lamp 8 is to be turned on is output based on three kinds of judgment signals supplied from the automatic lighting operation switch 4,
A lighting / extinguishing control circuit 3 that regulates an output signal according to opening / closing operation of the door switch 5, and a headlight that receives an output signal from the lighting / extinguishing control circuit 3 and selectively turns on the headlight 7 and the tail lamp 8 in a predetermined mode. It is composed of a tail lamp control circuit 6 and the like.

The automatic lighting operation switch 4 installed in front of the driver's seat is switched to an on state when the auto light drive control device is to be operated, and is switched to an off state when the auto light drive control device is to be inactivated. When the ignition switch (not shown) is in the ON state, the switching operation to the state is not effectively operated unless the operation of the lighting control circuit 3 is canceled by the door switch 5. The door switch 5 is for canceling the lighting state of the headlight 7 when the ignition switch is turned off while the automatic lighting operation switch 4 is kept on, and the driver opens the door to leave the vehicle.

Then, when the driver opens the door, the set state of the lighting / extinguishing control circuit 3 and the like is released, and the function of the automatic light drive control device is stopped.

However, at this time, when the vehicle is driving in a bright environment during the daytime, the level change detection circuit 2 outputs a signal indicating the daytime, so that the lighting control circuit 3 controls the headlight / taillight. No signal is output to the circuit 6.

Here, when the vehicle enters a tunnel, the traveling environment changes abruptly, and the signal output from the level change detection circuit 2 changes from a signal indicating the daytime to a signal indicating the nighttime. The control circuit 3 is a headlight
A control signal is output to the tail lamp control circuit 6 to turn on both the headlight 7 and the tail lamp 8.

When driving in a dimly lit environment, the level change detection circuit 2 outputs a signal indicating the evening, so that the lighting control circuit 3 controls the headlight / taillight control circuit 6. It outputs a control signal for turning on the tail lamp 8.

Next, the wireless engine starting device will be described with reference to FIG. That is, when the switch 11 provided in the transmitter 10 is turned on, a code signal indicating an engine start instruction and a code signal indicating an engine stop instruction signal, which are set and stored in a circuit built in the transmitter 10, are output from the transmitting antenna 12. , Is received by the receiver 14 via the receiving antenna 13. The code signal received by the receiver 14 is supplied to the code analysis circuit 15,
Therefore, if code analysis is performed and the received signal is a signal instructing engine start, an engine start start signal is output,
If the signal is an instruction to stop the engine, an engine start / stop signal is output to the engine drive circuit 16.

[0010]

However, the above devices have been developed separately by different companies,
Because it is sold as an option method at the dealer,
When users purchase and install them, they have the following problems because they have only separate functions.

When remote starting is performed with the auto light switch set, the headlights and tail lamps are lit at night, and the lamps remain lit even after the engine is stopped depending on the vehicle model, causing a problem of battery exhaustion. there were.

Further, since the headlight and the tail lamp are left unattended, there is a problem that anxiety and discomfort are given to a nearby person.

As a method for improving this, an improvement in which the auto light switch function is simply made non-functional has been proposed, but the following problems have been caused because the headlights and the tail lamps are turned off.

That is, when a vehicle is parked in a large-scale parking lot at night and there is a large number of similar vehicles and the surroundings are dark and cannot be seen well when trying to find the vehicle in the process of leaving. There was a problem that it took time to find my vehicle.

The present invention has been made in view of such a problem, and the switch of the wireless engine starter is operated in a predetermined mode while the automatic lighting operation switch of the autolight drive controller is kept in the ON state. By operating the engine start signal and engine stop signal at predetermined timings, the headlights, small lamps, etc. can be turned on automatically, or the engine can be warmed up with the lights off. It is also an object of the present invention to provide a device that can be selectively used.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. An embodiment of the present invention will be described below with reference to FIG. The configuration will be described with reference to FIG. 1. However, the same configurations as those described in FIGS. 4 and 5 or equivalent components will be denoted by the same reference numerals and the description thereof will be omitted, and different switch circuits 17 will be described. Only described below.

That is, in FIG. 1, reference numeral 16 'denotes an engine drive circuit, which has the same function as that of the engine drive circuit 16 shown in FIG. 5 and also has an instruction for instructing the engine to start from the code analysis circuit 15. When the signal and the instruction signal for instructing to stop the engine are continuously supplied at a predetermined time interval, the operation is started according to the last supplied instruction signal. When the instruction signal for instructing the engine to be driven is supplied from the code analysis circuit 15, the engine drive circuit 16 ′ outputs an off signal to the first switch circuit 18, and thereafter an ignition switch (not shown), Signals for driving the starter motor and the like are output in a predetermined order, the starter motor is stopped when the engine is started, and the idling operation is continued for a predetermined time.

A pressing operation mode analysis circuit 19 inputs an engine start start signal and an engine stop signal output from the receiver 14, and only when these signals are continuously supplied at a predetermined time interval, That is, when it is determined that the pressing operation mode of the switch 11 is the predetermined mode, the second switch 20 described later is turned on. The order in which the engine start signal and the engine stop signal are supplied to the pressing operation mode analysis circuit 19 has no effect on the determination of the predetermined mode.

Reference numeral 20 is a second switch composed of a transistor, the collector of which is connected to the connection line between the turn-on / off control circuit 3 and the first switch 18, the emitter of which is grounded, and the base of which is the pressing operation mode analysis circuit 19. It is connected to the output terminal and is turned on based on the output signal from the pressing operation mode analysis circuit 19 to equivalently generate a signal equivalent to that when the automatic lighting operation switch 4 and the first switch 18 are turned on. It is for making it.

Next, the operation of the above configuration will be described with reference to FIGS. (Normal time) In FIG. 2, the driver leaves the vehicle while keeping the automatic lighting operation switch 4 in the ON state, and then the transmitter 10 is used to start the engine by remote control at night.
When the switch 11 is temporarily turned on (time T1), a signal for starting the engine is supplied to the engine drive circuit 16 'through the receiver 14 and the code analysis circuit 15.
The engine drive circuit 16 'makes a pseudo-state in which the first switch circuit 18 is turned off and the automatic lighting operation switch 4 (in FIG. 4, it is referred to as the auto light switch 4) is artificially created, and headlights and the like are generated even when the engine is started. Then, at time T2, the accessory switch, the ignition switch, and the starter motor are driven in this order to start the engine (corresponding to engine driving in FIG. 2).

After that, at time T3, the driving of the engine is stopped, the ignition power source is turned off, and then the engine drive circuit 16 'turns on the first switch circuit 18, whereby the auto light switch 4 is turned on (time T5). .

(Using the transmitter 10 to turn on the headlight 7 and the tail lamp 8) In FIG. 3, the driver leaves the vehicle while keeping the automatic lighting operation switch 4 in the ON state.
After that, if the switch 11 of the nighttime transmitter 10 is continuously pressed in a predetermined mode, that is, continuously pressed within a predetermined time to generate an engine stop signal (time T1) and an engine start signal (time T2). The pressing operation mode analysis circuit 19 determines that the input mode is a predetermined mode, the second switch circuit 20 is turned on, and the auto light switch is equivalently turned on regardless of the true state of the auto light switch. To be done.

As the signal from the receiver 14, a signal for starting the engine is supplied to the engine drive circuit 16 'through the code analysis circuit 15, and the engine drive circuit 1'is supplied.
6'starts the engine by driving the accessory switch, the ignition switch, and the starter motor in this order at time T2 (corresponding to engine driving in FIG. 3). At that time, since the ignition switch is turned on and the auto light switch is pseudo turned on, the lighting control circuit 3 is activated to turn on the headlight 7 and the tail lamp 8, and then at time T3, the ignition switch and the accessory are turned on. The switch is turned off and the drive of the engine is stopped.

After that, at time T3, the ignition switch and the accessory switch are turned off and the driving of the engine is stopped, but the headlight 7 and the tail lamp 8 continue to be turned on. The engine drive circuit 16 'turns off the first and second switch circuits 18 and 20 at time T3, forcibly turns off the switch 4 equivalently, and turns on the ignition power supply again at time T4. (T4 time in the timing chart at the bottom of FIG. 2). Accordingly, the lighting / extinguishing circuit 3 reads the switch 4 again, and therefore detects that the autolight switch is equivalently turned off, and turns off the headlight 7 and the tail lamp 8. afterwards,
After the ignition switch power supply is turned off, the switch 18 is turned off and the switch 4 is released from the equivalent off state.
