2. Description of the Related Art A remote control device for an automobile engine for starting an engine of an automobile placed outdoors, such as a parking lot, from the interior of the vehicle has been known as disclosed in Japanese Utility Model Laid-Open No. 2-42102. And some are actually used. When starting an automobile engine using a remote control device, a portable transmitter is operated to emit a radio signal. This wireless signal is received by a receiver provided on the vehicle side and sent to the controller. The controller issues a start command signal only when the receiver receives a radio signal from the transmitter and a condition such as safety is satisfied. On the basis of this start command signal, an ignition switch constituting the start device is closed, the starter motor is driven, and the engine is started.

[0003] In addition, it has been conventionally performed to incorporate a door lock opening / closing function, an air conditioner operation function, and the like into such a remote control device for an automobile engine. For example, in the case of a remote control device incorporating the operation function of an air conditioner, in cold weather such as winter, the engine is started by remote control, and then the air conditioner is driven to blow defrost on the inner surface of a windshield. By blowing moderately heated air from the mouth, it is possible to remove fogging due to fine water droplets generated on the inner surface of the windshield and frost adhering to the outer surface of the windshield.

[0004]

However, in the case of the above-mentioned conventional remote control device for an automobile engine, in a cold season such as winter, the windshield can be defrosted and defrosted as described above. Defrosting and defrosting could not be performed properly. The reason for this is that the function of operating a rear window defogger for performing defrosting and defrosting of the rear glass has not been incorporated in the conventional remote control device for an automobile engine. As is well known, the rear wind defogger is a device that heats the rear glass based on applying a current to a conductive wire (heating wire) attached to the rear glass over substantially the entire inner surface of the rear glass.

However, even if the remote control device of the vehicle engine does not have such a function of operating the rear wind defogger, the operation of the rear wind defogger must be performed before starting the engine by the remote control device. If the switch is turned on, the rear window defogger can be activated simultaneously with the start of the engine by the remote control device. However, in such a case, it is not necessary to perform the defrosting and defrosting of the rear glass (for example,
This is not preferable because the rear wind defogger operates even during warm weather such as summer. The vehicle engine remote control device of the present invention has been invented in view of the above-described circumstances.

[0006]

According to the present invention, there is provided a remote control apparatus for an automobile engine, comprising: a transmitter for issuing at least a radio signal for instructing starting of the engine; and a receiver for receiving a radio signal from the transmitter. A controller for issuing a start command signal when the receiver receives a radio signal, a starting device for starting an engine based on the start command signal, and a signal representing the temperature by detecting the temperature in the vehicle compartment Is input to the controller. Then, the controller, when the engine is started by the starting device based on the start command signal, only when the temperature in the vehicle interior is equal to or lower than a predetermined value, by operating a rear wind defogger, The rear window defogger is heated by the rear glass.

[0007]

In the case of the remote control device for an automobile engine according to the present invention having the above-mentioned structure, when the temperature in the interior of the automobile is lower than a predetermined value in cold weather such as winter, that is, at least fine water droplets on the inner surface of the rear glass. Only when the temperature is below the temperature at which fogging is expected to occur, the rear window defogger for heating the rear glass can be operated in accordance with the start of the engine by the remote control device. For this reason, it is possible to prevent the inconvenience of operating the rear wind defogger during warm weather such as in summer when it is not necessary to perform the defrosting and defrosting of the rear glass, and to appropriately perform the defrosting and defrosting of the rear glass.

Referring to the flowchart shown in FIG. 2, when the remote control device of the automobile engine is started, the judgment conditions stored in the RAM incorporated in the controller 3 are controlled by the controller 3. A so-called initial setting for transferring the data into the circuit is performed. After performing the initial setting, when the receiver 2 receives the radio signal from the transmitter 1 and conditions such as safety are satisfied, the engine is remotely controlled. That is, after the initial setting, the controller 3 always determines whether or not the receiver 2 is receiving a radio signal from the transmitter 1,
When it is determined that the receiver 2 is receiving the radio signal, the start / stop of the engine is controlled. That is, when a radio signal indicating that the engine should be started is sent from the transmitter 1 to the receiver 2, the engine is started by the starting device 4.

After the engine is started in this manner, the controller 3 controls the rear wind defogger 6 (FIG. 1) for heating the rear glass based on a signal sent from the room temperature sensor 5 and indicating the temperature in the vehicle interior. ) Is determined. That is, the controller 3 determines that the temperature in the vehicle interior is equal to or lower than a predetermined value, that is, the temperature (for example, 5 ° C.) or lower at which it is expected that at least the inner surface of the rear glass is clouded by fine water droplets. Only in such a case, the rear window defogger 6 is operated, and otherwise, the rear window defogger 6 is not operated.
By operating the rear wind defogger 6 in this manner, the rear glass is heated, and defrosting and defrosting of the rear glass is performed.
