Description

  The present invention relates to an alarm device for a vehicle.

Since the driver consciously reduces the speed when the police are carrying out speed control, if the driver is informed that speed control is being carried out, the vehicle can be operated safely.
For this reason, a vehicle alarm device that warns a driver when an approach of an emergency vehicle, speed control, or the like is detected is now widely used.

As shown in FIG. 10, the vehicle alarm device 100 specifically includes a reception unit 110, an alarm unit 120, and a prohibition unit 130.
Among these, the receiving unit receives a plurality of types of external signals that can be used for safe operation of the vehicle, such as approaching an emergency vehicle and speed control, from the outside of the vehicle. Specifically, the receiving unit receives a radio signal in a frequency band used in an emergency vehicle, or a signal such as a microwave transmitted from an automatic speed regulator (commonly referred to as Orbis).

  The warning unit issues a plurality of types of warnings to the driver of the vehicle based on each external signal received by the receiving unit. In other words, when the receiving unit receives a radio signal of a frequency pair used in an emergency vehicle or a microwave signal transmitted from Orbis, the alarm unit 120 notifies that the emergency vehicle is approaching or speed control. A warning is given with an audio signal, etc.

  The prohibition unit 130 performs prohibition setting for prohibiting one or more types of alarms by the alarm unit according to the operation of the driver. If you are familiar with the circumstances of the environment where you use the vehicle, such as in the town where the driver resides, the driver knows that the emergency vehicle is rarely approached. Doing so is often bothersome while driving. Therefore, the alarm is prohibited as needed by operating the prohibiting unit 130.

  By the way, in order to raise the driver's awareness of safe driving, the police may set a day of traffic fatal accident “0” to strengthen the control. In such a case, the police go out on the road and control in many places. Therefore, in the vehicle equipped with the vehicle alarm device 100 described above, warnings are frequently given and the driver's safety awareness is inevitably required. improves.

However, if the prohibition unit 130 is set so that no warning is given, the warning is not given, so the driver misses the opportunity to raise safety awareness.
Therefore, an object of the present invention is to provide a vehicular alarm device 100 that solves the above-described problems, cancels the prohibition setting as necessary, and allows safer operation of the vehicle.

  The vehicle alarm device according to claim 1, which is an invention made to solve the above-described problem, receives a plurality of types of external signals that are set in advance to be received as signals to be noted when operating the vehicle. A receiving means, an alarm means for executing an alarm corresponding to each of the external signals received by the receiving means for the driver of the vehicle, and one or a plurality of types of alarms by the alarm means according to the operation of the driver In a vehicle alarm device comprising prohibition means capable of performing prohibition setting for prohibiting prohibition, release condition storage means for storing release condition information, which is a condition for canceling the prohibition setting, and judgment that changes over time Determination information generating means for generating information; determination means for determining whether the determination information matches the release condition information; and the determination information in the release condition information When I do, it characterized in that it comprises a canceling means for canceling the prohibition setting.

  In this vehicle alarm device, release condition information, which is a condition for canceling the prohibition setting, is stored in the release condition storage means, and determination information that changes with time during operation of the vehicle alarm device is supplied to the determination information generation means. Is generated. In this vehicle alarm device, the determination unit determines whether or not the determination information matches the release condition information. If the determination information matches the release condition information, the release unit cancels the prohibition setting. For this reason, in this vehicle alarm device, even if the prohibition setting is performed, if the prohibition setting is performed, an unfavorable situation is set as a release condition. An alarm is issued regardless of whether or not.

  Therefore, if this vehicle alarm device is used, even if the prohibition setting is performed, an alarm is also given for the prohibition setting when the prohibition setting is not performed. Can be operated easily. In addition, even when the enforcement as described in the background of the background art is strengthened, even if the prohibition is set, a warning will be given, so the driver will not miss the opportunity to raise traffic safety awareness .

By the way, if the prohibition setting has been canceled as described above, an alarm is issued even if the prohibition setting is preferable.
Therefore, as described in claim 2, the vehicular alarm device according to the present invention determines that the determination information does not match the release condition information after the prohibition setting is released, assuming that the determination information matches the release condition information. It is preferable to provide resetting means for resetting the prohibition setting.

Next, as the judgment information, the following is assumed.
The first determination information is determination information related to the date and time described in claim 3.
In this case, if the information regarding the date when the “traffic accident 0” and “traffic safety week” when police enforcement is strengthened is memorized as a release condition, When the prohibition setting is released and a control signal is received as an external signal, an alarm is issued.

The second determination information is determination information related to the position of the vehicle described in claim 4. The position of the vehicle changes with time when the vehicle is operated.
In this case, position information of a specific region such as a region where control is performed may be set as the release condition information.

In addition, the weather information may be used as the determination information, and the weather information that the weather is rain may be set as the cancellation condition information.
Next, as described in claim 5, the determination information generating means includes GPS receiving means for receiving a position positioning signal from a GPS satellite, and generates determination information based on the position positioning signal. Also good. Since this positioning signal has a signal related to time, the received time can be known. Therefore, time information can be generated by using this position positioning signal.

  Next, as described in claim 6, the release condition information may of course include an input means for inputting to the release condition storage means in accordance with the operation of the driver. In this way, various release conditions can be set according to the driver's needs.

  Further, as described in claim 7, the receiving means may receive a signal transmitted from a speed measuring device for measuring the speed of the vehicle as one of the external signals.
