DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm device used in an automobile, and more particularly to an alarm device for a vehicle that warns when a suspicious person or the like approaches a vehicle for the purpose of preventing theft.

[0002]

Conventionally, various types of vehicular alarm devices have been proposed for the purpose of preventing theft of a vehicle. For example, an ignition switch is turned off by an owner, and a door is provided with a keyless device or a keyless device. When the alarm device is locked on, the warning device is alerted.In this alert condition, when the door, engine hood or trunk is opened without being unlocked normally or the key cylinder of the door is destroyed, it is mounted on the vehicle 2. Description of the Related Art A vehicular alarm device is known in which a horn continues to sound for a predetermined time and an alarm device that flashes a headlamp to notify an owner or a nearby person of an abnormality is activated.
There is also known a vehicle antitheft device configured to cut off a starter circuit of an engine so as to disable the running of the vehicle so that the engine cannot be started.

However, when an alarm is issued by blinking a horn or a headlamp as described above, the power consumption is so large that the battery as a power source may be discharged, that is, the battery may run out. Also, when the horn is sounded for a predetermined time as an alarm means, the problem is noise in a densely populated house or the like, and especially, since theft of a vehicle is often performed at midnight, it hinders sleep of neighboring residents. It can cause problems such as: In addition, the method of alarming by blinking a headlamp or a horn is applied to an alarm other than theft, for example, an alarm device that informs a driver of a danger such as a contact accident when the running vehicles approach each other when the vehicle is running. Even so, the flashing of the headlamp or the warning by the horn may significantly impede the driving of the oncoming vehicle or the vehicle traveling ahead. Therefore, such a warning by the blinking of the headlamp or the horn cannot be used also for a warning other than the theft, and the versatility is poor.

An object of the present invention is to solve such a problem, and it is an object of the present invention to provide a vehicular alarm device which suppresses current consumption of an illumination light source at the time of an alarm and has excellent versatility. .

When the suspicious person approaches the vehicle body for the purpose of theft or mischief, the approach detecting means detects that the suspicious person, which is the object, has approached the vehicle body within a predetermined distance. Thereby, the light emitting diode of the lighting unit is turned on, and a suspicious person is visually warned. This visual alarm uses an LED instead of a bulb as the illumination light source, so it consumes less current. At the time of the alarm, even if the illumination unit is turned on frequently, the burden on the battery is small and the reliability as a security alarm is improved. I do.

According to a second aspect of the present invention, there is provided a vehicle lighting device, wherein the control means includes a key illumination mode for illuminating around a key by an unlocking operation of a door; An alarm mode for issuing an alarm; and mode setting means for detecting whether the rearview mirror is at the use position and the storage position, and switching to a normal mode for stopping the sensor when the rearview mirror is at the use position.

Thus, when a legitimate driver approaches the vehicle body for driving, the light emitting diode of the lighting unit is turned on to illuminate around the keys. Can also be used.

According to a third aspect of the present invention, there is provided a vehicle lighting device, wherein the control means includes a key illumination mode for illuminating around a key by an unlocking operation of a door; An alarm mode for issuing an alarm, detecting whether the rear-view mirror is at the use position and the storage position, and when the rear-view mirror is at the use position and the ignition switch of the vehicle body is turned on, the distance between the vehicle and another traveling vehicle It has mode setting means for switching to a travel monitoring mode for detecting a distance.

[0010] Thus, when the distance from another traveling vehicle is too short during traveling, it is possible to give a warning notifying the driver of both the own vehicle and the other vehicle of the danger of a contact accident, and a security warning. It functions not only as a warning device but also as a warning device that warns of contact with other vehicles during traveling.

According to a fourth aspect of the present invention, in the warning mode, the emission color of the illumination unit is changed in accordance with the proximity of the object to the vehicle body in the alarm mode.

[0012] This makes it possible to give a more visual warning to a suspicious person approaching the vehicle body, so that a warning with a higher security function can be given.

According to a fifth aspect of the present invention, there is provided a vehicle lighting device in which the lighting unit and the approach detecting means are incorporated inside the rearview mirror.

This makes it possible to compactly incorporate the approach detecting means for detecting the object and the illumination unit for giving an alarm inside the rearview mirror.
