Description

The present invention relates to a hazard lamp control device for a vehicle traveling on a public road.

Hazard lamps are provided on vehicles traveling on public roads such as passenger cars and cargo vehicles. Usually, direction indication lamps provided at the front and rear of the vehicle are also used as hazard lamps, and are operated as hazard lamps by the operation of the driver. By pressing a switch provided in the driver's seat, the control device recognizes the operation instruction and blinks the hazard lamp based on a predetermined cycle. This blinking cycle is fixed for each vehicle.

Patent Document 1 discloses a vehicle including a hazard lamp control device instructing unit that instructs a hazard lamp control device to blink a hazard lamp in a second cycle different from the normal first cycle in response to an emergency stop operation. A control device is described. This blinking in the second cycle is executed in conjunction with an emergency stop operation such as an ignition switch off operation during traveling, and the occupant does not perform an operation for blinking the hazard lamp (paragraph 0068 of the same document).

Japanese Patent Laid-Open No. 2011-245968

A hazard lamp provided in a conventional vehicle can be blinked by an operation of a button switch, and an intention can be displayed around. In reality, however, hazard lamps are used for purposes other than to indicate an emergency situation, and are usually used to indicate that the vehicle is parked or to show appreciation for the passengers behind the vehicle. It is. Therefore, even if the hazard lamp blinks to notify that a danger has occurred, the person who sees it does not always recognize the danger occurrence. Use for purposes other than to indicate an emergency is different from the original purpose of the hazard lamp, but such habits are already widespread, and it contributes to smooth traffic, so it is uniformly restricted. It is not realistic to do.

Since the vehicle control device of Patent Document 1 causes the hazard lamp to blink in a second cycle different from the normal first cycle in response to an emergency stop operation, a state different from the blinking of the normal hazard lamp may occur. Can be shown. However, the blinking of the second cycle must occur unless it is an emergency stop operation. However, the case where an occupant recognizes an emergency situation and the case where an emergency stop operation is performed are not necessarily the same. Even without an emergency stop, it may be recognized as an emergency. When driving on a highway at high speed, performing an emergency stop operation to blink the hazard lamp may lead to a greater danger.

In addition, although it is not an urgent danger, there are cases where it is desirable to call attention to the surroundings. As already described, since the conventional hazard lamp substantially loses such significance, it is desirable that the warning level and the level that can be said to be more serious can be distinguished and displayed. And since such a urgency is most grasped by the vehicle occupant, it is desired that the occupant can operate based on the determination.

An object of the present invention is to provide a vehicle hazard lamp control device that allows a vehicle occupant to indicate the occurrence of caution or danger to the outside in accordance with the situation.

In order to solve the above problems, a vehicle hazard lamp control device of the present invention is
A hazard relay for generating a flashing signal of a hazard lamp with a first cycle, a second cycle shorter than the first cycle, and a third cycle shorter than the second cycle;
A first switch for operating a hazard relay and a hazard lamp in a first cycle;
A second switch for operating the hazard relay and the hazard lamp in a second period;
A third switch for operating the hazard relay and the hazard lamp in a third period;
The hazard lamp is activated based on any of the first, second, and third switch operations by the vehicle occupant. In particular, the first hazard relay, the second hazard relay, and the third hazard relay are individually provided, and the first cycle, the second cycle, and the third cycle are respectively generated to simplify the configuration. Can be. Since the first period is approximately 60 times / minute, the second period is approximately 90 times / minute, and the third period is approximately 120 times / minute, all the periods are 60 times / minute or more. It can be within the range of 120 times / minute, and the difference in each blinking period is clearly recognized.

The automatic survey system according to the present invention includes the above-described vehicle hazard lamp control device and the hazard lamp, and activates the hazard lamp based on any one of the first, second, and third switch operations by the vehicle occupant. .

The vehicle hazard lamp control device according to the present invention can perform display according to the degree of urgency that the occupant wants to inform the outside by operating the occupant. The configuration can be simple and inexpensive, and can be performed without affecting the configuration of the vehicle.

It is a block diagram which shows the structure of the hazard lamp control apparatus for vehicles. It is a front view which shows the example of a switch.

EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated in detail based on drawing. FIG. 1 is a block diagram showing a configuration of a vehicle hazard lamp control apparatus. In this example, it can be easily configured using elements that are already widely used, and can be realized by several methods. Therefore, in this example, generalization and simplification are shown to show the main configuration and operation of the invention. It is shown.

The vehicle hazard lamp control device 1 operates a hazard lamp 2 provided in a vehicle. The hazard lamps 2 are not particularly limited, and those used in current vehicle types may be used as they are. Usually, it is also used as a direction indicator (blinker lamp), and in this example, lamps provided in left and right pairs before and after the vehicle are used. Accordingly, FIG. 1 also shows a configuration related to the control of the direction indicator.

The vehicle hazard lamp control apparatus 1 includes three types of hazard relays 3a, 3b, and 3c. The hazard relays 3a, 3b, and 3c are preferably inexpensive and highly reliable. For example, a semiconductor relay or the like may be used, but in this example, a normal contact relay using an electromagnet is used. Yes. The three types of hazard relays 3a, 3b, and 3c perform ON-OFF operations at different periods. In this example, the first hazard relay 3a performs an ON-OFF operation with a first cycle Ca that is approximately the same as the blinking cycle of the hazard lamp of a conventional passenger car. For example, even if the hazard relay for a conventional passenger vehicle is used, Good.

The second hazard relay 3b performs an ON-OFF operation with a second cycle Cb shorter than the first hazard relay 3a, and the third hazard relay 3c is ON-with a third cycle Cc shorter than the second hazard relay 3b. Performs an OFF operation. According to the current law, the blinking cycle of the hazard lamp is set to 60 to 120 times / minute. In most conventional vehicles, a cycle of about 60 times / minute is used. Therefore, by selecting the first cycle Ca at about 60 times / minute, the second cycle Cb at about 90 times / minute, and the third cycle Cc at about 120 times / minute, the current law relating to road traffic is selected. In the case where the first cycle Ca is selected, the flashing cycle is approximately the same as that of the conventional vehicle hazard lamp.

The vehicle hazard lamp control apparatus 1 includes three switches for operating the hazard lamps. FIG. 2 is a front view showing an example of a switch for operating a hazard lamp. In this example, three push button switches are provided side by side. Each switch 4a, 4b, 4c can be switched between a pressed state (ON state) and a non-pressed state (OFF state) by pressing a button. In addition, when a switch (for example, switch 4a) is in an ON state, the other switches (for example, switches 4b and 4c) are in an OFF state. The switch (switch 4a) that has been changed to the OFF state. Further, each of the switches 4a, 4b, 4c also has an action of disconnecting a connection between a winker relay (to be described later) and the lamp 2 when turned on.

On the surface of the switches 4a, 4b and 4c, a display is provided so that each can be identified. For example, one red triangle is displayed on the first switch 4a as in the case of a normal hazard switch. If two triangles are displayed on the second switch 4b and three triangles are displayed on the third switch 4c, the degree of urgency required by each switch can be shown in an easy-to-understand manner. Each switch 4a, 4b, 4c has a built-in lamp, and each display illuminates when lit. In addition, a transparent cover that can be easily removed may be attached on the second switch 4b and the third switch 4c, so that the second switch 4b and the third switch 4c are not accidentally pressed in normal times. May be.

The vehicle is provided with a winker relay 5 for acting as a direction indicator, a winker switch 6, a battery 7, and an activation device 8 such as an ignition switch.

The blinker relay 5 is connected to the battery 7 via the activation device 8. Therefore, it does not operate when the activation device 8 is in the OFF state (disconnected state). The blinker switch 6 is a three-contact selection switch that can select three states of a disconnected state, a left connected state, and a right connected state. The input side 6 in of the winker relay 5 and the winker switch 6 is connected via an intermediate switch 9. This intermediate switch 9 is in an ON state (connected state) when all of the three hazard lamp switches 4a, 4b, 4c are in an OFF state, and any of the hazard lamp switches 4a, 4b, 4c is in an ON state. Sometimes the intermediate switch 9 is in the OFF state.

The left output side 6L of the winker switch 6 is connected to the front left lamp 2FL and the rear left lamp 2RL, and the right output side 6R is connected to the front right lamp 2FR and the rear right lamp 2RR. . When the starter 8 and the intermediate switch 9 are in the ON state, when the winker switch 6 is in the left connection state, the battery 7 is connected to the left lamps 2FL and 2RL via the winker relay 5, and these two lamps Blinks at the cycle of the relay 5 for use. On the other hand, when the right connection state is selected, the right lamps 2FR and 2RR blink. Since the winker switch 6 cannot be connected to the left and right lamps simultaneously, the left and right lamps cannot be blinked simultaneously by operating the winker switch 6. Although the configuration and operation of the direction indicator have been described above, they are basically not different from those used in conventional vehicles.

On the other hand, each of the hazard relays 3a, 3b, 3c is directly connected to the battery 7 without going through the activation device 8. Further, the first hazard relay 3a is connected to the first switch 4a, the second hazard relay 3b is connected to the second switch 4b, and the third hazard relay 3c is connected to one end of the third switch 4c. The other ends of the three hazard lamp switches 4a, 4b, 4c are connected to all four lamps 2, respectively.

Normally, all of the hazard lamp switches 4a, 4b, 4c are in the OFF state. When one of the switches (for example, the second switch 4b) is pressed, the switch is turned on. And the hazard relay (for example, 2nd hazard relay 3b) corresponding to the switch is connected with all the lamps. If another hazard lamp switch (for example, switch 4a or 4c) is in the ON state, it is switched to the OFF state. The intermediate switch 9 is also switched to the OFF state. Then, all the lamps 2 blink simultaneously according to the cycle of the selected hazard relay (for example, the second hazard relay 3b).

The vehicle hazard lamp control device of the present invention is manually operated by a vehicle occupant or the like. It will not be activated or deactivated by other factors.

In normal operation, the vehicle occupant selects a state in which all the switches 4 are OFF. At this time, none of the hazard relays 3 operates. Since the winker intermediate switch 9 is in the ON state, if the starter 8 is in the ON state, either the left or right lamp can be blinked at the cycle of the winker relay by operating the winker switch.

When it is desired to turn on the hazard lamp in the same situation as when using the conventional hazard lamp, the occupant presses the first switch 4a to turn it on. By this operation, the intermediate switch 9 is turned off, so that the blinker relay does not operate and the one side of the lamp as a direction instruction does not blink. Then, the first hazard relay 3a generates a blink signal in the first cycle Ca, and all the four lamps 2 blink simultaneously in the first cycle Ca. Further, the pilot lamp inside the first switch 4a also blinks in synchronization.

When the occupant recognizes a state that he / she wants to call attention to the outside, the second switch or the third switch can be pressed according to the urgency. In the example of FIG. 2, since a cover that can be easily removed is attached, this cover is removed and the buttons are operated. If the second switch 4b is pressed, the second hazard relay 3b blinks in the second cycle Cb, and if the third switch 4c, the third hazard relay 3c blinks in the third cycle Cc. Since each period is different, even if the same lamp blinks, an outside person can clearly determine the degree of urgency and can take a corresponding action. A vehicle occupant or the like can operate the switch 4 based on his / her judgment to indicate his / her urgency recognized outside.

In this example, three sets of hazard relays and switches are provided independently corresponding to the respective periods. Therefore, it can be considered that three hazard lamp systems are provided in parallel. And since all are in the period of 60 or more and 120 or less, it is a hazard lamp adapted to the current regulations, and it is considered that the operation is legal even if any switch is operated.

Further, the above-described embodiment is implemented with a small change by adding the second hazard relay 3b, the third hazard relay 3c, the second switch 4b, and the third switch 4c to the conventional vehicle hazard lamp control device. Can do. Therefore, the present invention can be carried out without greatly changing the design and production process of the conventional vehicle hazard lamp control apparatus. Since only two inexpensive elements, relays and switches, are added, the cost increase is slight. Since it has followed the proven and reliable basic structure and parts used so far, there are few risks associated with new technologies.

Further, by using the switch shown in FIG. 2, it is possible to replace the conventional hazard switch. In many passenger cars, a hazard switch having a large horizontally long shape is used. Therefore, the switch shown in FIG. 2 can be turned on at that position. Therefore, a vehicle to which the hazard lamp control device of the present invention is applied can be realized without substantially affecting other configurations of the conventional vehicle. Furthermore, it can be applied to an automobile in use with a simple and inexpensive modification.

The present invention can also be applied in a form different from the example shown in FIGS. In vehicles such as trucks, the hazard switch is often used as a wiper operation lever. By pulling this lever toward you, the hazard lamp is turned on. In such a vehicle, the wiper operating lever is used as the first switch, connected to the first hazard relay, and the second switch 4b and the third switch 4c are added to different positions. be able to.

Furthermore, the hazard relay may be configured by a single relay having a variable cycle, and may be configured to switch three cycles by operating a switch.
