Description

  The present invention relates to a hazard lamp blinking control device.

  In general, a car is provided with a hazard lamp for urging attention to surrounding vehicles. This hazard lamp is also used as a turn signal lamp that blinks when making a right or left turn, and is generally provided on the left and right front, left and right sides, and left and right rear of the vehicle. The driver needs to call attention to surrounding vehicles, such as when traveling backwards, when stopping to attach a chain on a snowy road, or when the vehicle has stopped due to a breakdown. In some cases, a hazard lamp switch provided in the vehicle is operated to blink the hazard lamp to alert the surrounding vehicles.

  Such a hazard lamp is operated by a switch operation as described above. However, it is not uncommon for the hazard lamp to be forgotten to be blinked when it is desirable to forget the switch operation and blink the hazard lamp. In consideration of such a case, a hazard lamp blinking control device has been proposed in which the hazard lamp blinks automatically when the shift lever is moved to the reverse travel position when the ignition switch is on (Patent Document). 1).

In addition, a hazard lamp blinking control device has been proposed in which a hazard lamp blinks automatically for a certain time after the ignition switch is turned off (Patent Document 2).

However, in such a hazard lamp flashing control device, for example, when the driver forgets to operate the hazard lamp switch when the vehicle stops on the road shoulder due to a vehicle failure and the driver gets off, the hazard lamp flashes automatically. Therefore, there is a problem that it is impossible to call attention to surrounding vehicles. In addition, if the driver gets off and closes the door, he / she notices that he has forgotten to turn on the hazard lamp, so it is necessary to open the door and operate the hazard lamp switch. There is a problem.
An object of the present invention is to provide a hazard lamp blinking control device that automatically blinks a hazard lamp when a vehicle is stopped while the vehicle is powered on on a road and a passenger gets off.

  In order to solve the above-mentioned problem, the invention according to claim 1 is directed to an on / off state of a hazard lamp switch for performing blinking operation of a hazard lamp provided around a vehicle body of an automobile, and an ignition switch for turning on / off the power of the automobile. The blinking of the hazard lamp is controlled based on the on / off state of the vehicle, the on / off state of a door switch that detects the open / closed state of each door of the vehicle, and the position information output by the position detection device that detects the position of the vehicle. A hazard lamp blinking control device, wherein when the hazard lamp switch is in an off state and the ignition switch is in an on state and the position information detects that the automobile is on a road, a specific one of the doors After the door has been opened from the closed state, the door is open after a predetermined time has elapsed. It is characterized by blinking the hazard lamp when it is Luo closed.

  According to the above configuration, the hazard lamp can be automatically blinked when the vehicle is temporarily stopped on the road while the vehicle is powered on and the vehicle gets off.

  According to the present invention, it is possible to realize a hazard lamp blinking control device that automatically blinks a hazard lamp when a vehicle is stopped on the road while the vehicle is turned on and the passenger gets off.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a block diagram of a first embodiment of the present invention.

  The hazard lamp blinking control device 1 includes a position detection unit 1A, an ignition switch (described as IGNSW in FIG. 1) state detection unit 1B, a hazard lamp switch (described as hazard SW in FIG. 1) state detection unit 1C, and a door switch (FIG. 1). In this case, the state detection unit 1D and the control device main body 1E are provided.

  The hazard lamp 10 includes hazard lamps 10A and 10B attached to the left and right front sides of the vehicle body, hazard lamps 10C and 10D attached to the left and right sides of the vehicle body, and hazard lamps 10E and 10F attached to the left and right rear sides of the vehicle body. (10B to 10E are not shown).

  The hazard lamp blinking control device 1 takes in signals from the navigation device 2, the ignition switch 3, the hazard lamp switch 4, and the door switch 5, which are position detection devices, and causes the hazard lamp 10 to blink based on these signals.

  The navigation device 2 includes a storage unit 2A, and map information including latitude and longitude information of roads is stored in the storage unit 2A. The navigation device 2 outputs the latitude / longitude information of the road and the latitude / longitude information from the GPS satellite received by the antenna 2B to the electrically connected position detection unit 1A. The position detection unit 1A compares the received latitude / longitude information of the road with the latitude / longitude information of the vehicle, and determines that the vehicle is on the road when the latitude / longitude information is within a predetermined error range. The determination result is output to the control device main body 1E.

  The ignition switch 3 is in a battery power supply state (not shown, shown as BAT in FIG. 1) when it is turned on, and is opened when it is off. The ignition switch state detector 1B electrically connected to the ignition switch 3 detects this state, recognizes the on / off state of the ignition switch 3, and outputs the recognition result to the control device main body 1E.

  The hazard lamp switch 4 is in a grounded state when turned on, and is opened when it is turned off. The hazard lamp switch state detector 1C electrically connected to the hazard lamp switch 4 detects this state, recognizes the on / off state of the hazard lamp switch 4, and outputs the recognition result to the control device main body 1E. Here, when the hazard lamp switch 4 is in the ON state, the control device main body 1E does not depend on the outputs of the position detector 1A, the ignition switch state detector 1B, and the door switch state detector 1D (described later). 10 is blinked.

  The door switch 5 includes a driver-seat-side door switch 5A provided near the side sill on the driver's seat side, a passenger-side door switch 5B provided near the side sill on the passenger's seat, and a side-sill on the right side of the rear seat. A seat right door switch 5C and a rear seat left door switch 5D provided near the side sill on the left side of the rear seat are provided. The door switches 5A to 5D are turned on when the doors are closed to be in a grounded state, and are turned off and opened when the doors are opened. The door switch state detector 1D electrically connected to each door switch 5A to 5D detects this state, recognizes the on / off of each door switch 5A to 5D, and outputs the recognition result to the control device body 1E. To do.

  The control device main body 1E is arranged between the hazard lamp 10 and the battery power source based on signals taken from the position detection unit 1A, the ignition switch state detection unit 1B, the hazard lamp switch state detection unit 1C, and the door switch state detection unit 1D. A current is intermittently passed through a connected relay coil (not shown) to turn on and off the contact of the relay. When the relay contact is on, the hazard lamp is connected to the power source and lights up. When the relay contact is off, the hazard lamp is cut off from the power source and turned off. By this operation, the hazard lamp blinks.

  Next, details of the operation of the hazard lamp blinking control device 1 will be described using the state transition diagram shown in FIG.

  When the hazard lamp switch 4 is off, the control device main body 1E is in a state S1 where the hazard lamp 10 is not blinked.

  When the driver operates the hazard lamp switch 4 to turn it on, the control device main body 1E enters the normal blink mode state S2 in which the hazard lamp 10 blinks based on the state of the hazard lamp switch 4 (arrow in FIG. 2). a12).

  In the state S2, when the driver operates the hazard lamp switch 4 to turn it off, the control device main body 1E returns to the state S1 where the hazard lamp 10 is turned off based on the state of the hazard lamp switch 4 (arrow in FIG. 2). a21).

  When the condition lamp A (described later) is satisfied when the hazard lamp switch 4 is off, the control device main body 1E enters the automatic flash mode state S3 in which the hazard lamp 10 automatically flashes (arrow a13 in FIG. 2). ).

  Here, the condition A is a condition for determining whether or not an occupant gets off after stopping on the road with the ignition switch 3 turned on. The condition A1 “the ignition switch 3 is turned on”, the condition A2 “vehicle”. Is on the road. ", AND determination of the three conditions of Condition A3," A certain door has changed from the open state to the closed state after elapse of a predetermined time T1 after the door has changed from the closed state to the open state. " .

  The condition A1 is determined by the ignition switch state detector 1B based on the state of the ignition switch 3, and the control device body 1E receives this determination result.

  The condition A2 is determined by the position detection unit 1A based on the position information fetched from the navigation device 2, and the control device body 1E receives this determination result.

  The condition A3 is determined by the control device body 1E based on the state changes of the door switches 5A to 5D detected by the door switch state detection unit 1D. That is, the control device main body 1E includes a time TF when the door of the driver's seat changes from the closed state to the open state and the door switch 5A changes from on to off, and then the door switch changes from the open state to the closed state. The time TN when 5A changes from OFF to ON is stored, and it is determined whether or not the difference between TN and TF is equal to or greater than a predetermined value T1. The same determination is performed for the other door switches 5B to 5C. At this time, if the condition A3 is satisfied, it is determined that the passenger has got off the vehicle.

  When the hazard lamp 10 is in the automatic flashing mode state S3 and the hazard lamp switch 4 is switched from OFF to ON, the state shifts from the automatic flashing mode state S3 to the normal flashing mode state S2 (arrow in FIG. 2). a31).

  With the above operation, when the ignition switch 3 is on and the vehicle is on the road and the same door is closed after a predetermined time T1 has elapsed since the door opened, the hazard lamp 10 is automatically blinked. As a result, when the vehicle breaks down, when a chain is installed on a snowy road, or when waiting for a person, the driver stops on the road, such as the shoulder, with the ignition switch 3 turned on, and closes the door. At this time, even if the user has forgotten to operate the hazard lamp switch 4, the hazard lamp 10 automatically blinks, and the surrounding vehicles can be alerted.

  Further, the hazard lamp 10 blinking in the automatic blink mode can be turned off only by operating the hazard lamp switch 4. Therefore, after the automatic flashing mode, the blinking continues without being influenced by the on / off state of the door switch 5, so that the hazard lamp 10 is turned off even if the door is opened / closed by loading / unloading of luggage during the automatic flashing mode. There is no end.

  As mentioned above, although the Example of this invention was explained in full detail with drawing, an Example is only an illustration of this invention and this invention is not limited only to the structure of an Example. Accordingly, it is a matter of course that the present invention includes any design change within a range not departing from the gist of the present invention.

  For example, in the present embodiment, the hazard lamp 10 is blinked using a relay, but the hazard lamp 10 may be blinked using an electronic switching element such as an FET.

  The number of hazard lamps 10 is not limited to the number shown in the first embodiment.

  The number of door switches 5 is not limited to the number shown in the first embodiment.

  Also, other methods may be used as a method for determining whether the vehicle is on the road.

  Furthermore, a switch for canceling the automatic lighting mode may be provided so that the driver can select the automatic lighting mode according to the situation.
