Abstract

PURPOSE:To improve traffic safety at the time of sudden deceleration by driving both right and left turn signal lamps at the time of detecting the sudden deceleration of a vehicle, and giving the driving of the turn signal lamps precedence over the detection of sudden deceleration of the vehicle in the case of either one of the right and left turn signal switches being operated. CONSTITUTION:A computer 11 (driving means) receives the respective detection signals of a hazard switch SW1 turned on by manual operation, a brake switch SW2 turned on at the brake stepping in time, an acceleration sensor S for detecting the sudden deceleration of a vehicle, and a left and a right turn signal switches SWL, SWR operated manually. When both turn signal switches SWL, SWR are in the 'off' state, the computer 11 discriminates whether or not the brake switch SW2 is 'on' (decelerated), and in the case of 'on', discriminates whether or not the detection signal of the acceleration sensor S is 'on' (sudden deceleration). In the case of 'on', a left and a right turn signal lamps 15L, 15R are lighted (or flashed) simultaneously so as to inform the other vehicle of the sudden decelerating state.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a hazard device for a vehicle.

(Prior Art) Generally, a vehicle hazard device turns on (or flashes) both left and right turn signal lamps at the same time in order to notify other vehicles of the occurrence of an emergency situation. In addition to the above, devices that automatically detect and notify emergency situations are also known.

FIG. 3 shows a conventional hazard device, with computer 1
Power is supplied from an on-vehicle battery 2 via an ignition switch 3 and a fuse 4.

The computer 1 has a hazard switch SWI that is turned on by manual operation using power from the on-board battery 2, and a brake switch S that turns on when the brake is stepped on.
W2 and an acceleration sensor S for detecting sudden deceleration of the vehicle
The emergency state is detected by any one of the detection signals, and both the left and right turn signal lamps 5L and 5R are turned on (or flashed).

Therefore, according to the above-mentioned conventional example, the left and right turn signal lamps 5L and 5R for left turn, right turn, and lane change constitute the hazard lamp 5, and when driving on a highway or the like, when decelerating, the rear vehicle collision can be prevented.

(Problem to be Solved by the Invention) However, in the conventional hazard device described above, the left and right turn signal lamps 5L, 5 for left turn, right turn, and lane change are
Both R lights will alert you to an emergency situation, so when you are driving on a highway and make a left turn, right turn, or lane change while suddenly decelerating, turn signal lamps 5L and 5R are used as the original turn signals. There is a problem that it cannot be used as

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a hazard device that can use a turn signal lamp as a turn signal even when a vehicle suddenly decelerates.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a means for detecting the operating state of left and right turn signal switches, a detecting means for detecting sudden deceleration of a vehicle, and a means for detecting a sudden deceleration of a vehicle. If speed is detected, both the left and right turn signal lamps are activated, or if either of the left or right turn signal lamps A. and means for driving the operated turn signal lamp.

(Function) With the above configuration, the present invention drives the turn signal lamp with priority over detection of sudden deceleration of the vehicle when either the left or right turn signal switch is operated. Therefore, even when the vehicle suddenly decelerates, the turn signal lamp operates as a turn signal.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a hazard device according to the present invention.

In FIG. 1, the computer 11 (driving means) includes:
The power source of the vehicle battery 12 is the ignition switch 13
, a hazard switch SWI that is supplied through the fuse 14 and turned on by manual operation, a brake switch (deceleration detection means) SW2 that is turned on when the brake is stepped on, and detects sudden deceleration of the vehicle. acceleration sensor (sudden deceleration detection means) S, and left and right turn signal switches SW that are turned on by manual operation.
L.

Each detection signal of SWR is input. Note that the detection signal of the acceleration sensor S is turned on when the deceleration of the vehicle exceeds, for example, 0.2G.

Computer 11 is a central processing bag! (CPU) or the second
As shown in the figure, there is a read-only memory (ROM) in which CPU programs are pre-stored, a random access memory (RAM) which has a work area for the CPU, etc.
It has input/output ports for drive signals for the hazard lamps 15).

Next, the operation of the above embodiment will be explained with reference to FIG.

The CPU of the computer 11 lights up (or flashes) both the left and right turn signal lamps 15L and 15R when the ignition switch 13 is turned on (step 21) and when the hazard switch SWI is turned on (step 22). 23).

Therefore, the left and right turn signal lamps 15L and 15R for left turns, right turns, and lane changes constitute a hazard lamp 15, which can prevent a collision with a vehicle behind when the vehicle suddenly decelerates while driving on an expressway. .

On the other hand, if the hazard switch SW1 is off, the process branches from step 22 to step 24, and it is determined whether the left and right turn signal switches SWL and SWR are on (operated), and if they are on, the corresponding turn signal lamp is turned off. 15L
Or turn on (or blink) 15R (step 25)
.

If both the left and right turn signal switches SWL and SWR are off, the process proceeds to step 26, where it is determined whether the brake switch SW2 is on (deceleration), and if it is on, the process proceeds to step 27. In step 27, it is determined whether or not the detection signal of the acceleration sensor S is on (sudden deceleration). If it is on, the process proceeds to step 23, where the left and right turn signal lamps 15L and 15R are turned on (or flashed) at the same time.

In addition, in step 21, the ignition switch 13
is off, the brake switch SW2 is off in step 26, or the input signal from the acceleration sensor S is off in step 27, the turn signal lamp 15L or 15R is not turned on (or blinks).

In addition, when driving the left and right turn signal lamps 15L and 15R at the same time in step 23, the CPU of the computer 11 executes steps 21→22→2 during this driving.
3 loop or steps 21→22→24-27→23
The state of each detection signal is monitored by the loop.

Therefore, according to the above embodiment, in the control of the left and right turn signal switches SWL and SWR, first priority is given to the hazard switch SWI, second priority is given to the turn signal switches SWL and SWR, and following: brake switch SW2, ■Since priority is given in the order of acceleration sensor S, when driving on a highway, etc., while driving at speed
When making a right turn or changing lanes, operation of the turn signal switch (priority ■) takes priority over sudden deceleration detection (priority ■), and the turn signal lamps 15L and 15R can be used as the original turn signal.

(Effects) As explained above, the present invention includes a means for detecting the operating state of the left and right turn signal switches, a detecting means for detecting sudden deceleration of the vehicle, and a means for detecting the operation state of the left and right turn signal switches, and a detecting means for detecting the sudden deceleration of the vehicle. Drive both turn signal lamps, or
If either of the left or right turn signal switches is operated, the operated turn signal lamp is prioritized over detection of sudden deceleration of the vehicle. The lamp can be operated as a turn signal.
