DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
FIG. 1 is a block diagram showing an embodiment of a motorcycle overturn display device according to the present invention. FIG. 2 is a side view showing a motorcycle equipped with the motorcycle overturn display device shown in FIG.
[0012]
As shown in FIG. 2, in addition to the headlamp 2 and the tail lamp 3, the motorcycle 1 is provided with hazard lamps 4 for blinking the direction indicator lamp in the front, rear, left and right. An inclination angle sensor 6 that detects the inclination angle (camber angle) of the vehicle body 5 is attached to the center plane of the vehicle body 5. This inclination angle (camber angle) refers to an angle formed by the center plane of the vehicle body 5 and a perpendicular to the road surface.
[0013]
As shown in FIG. 1, the detection signal of the inclination angle sensor 6 is sent to a hazard system 7 and an electronic fuel injection device 8 which are composed of a CPU as control means. The hazard system 7 issues a blink command to the hazard lamp 4 via the electronic switch 9 when the inclination angle of the vehicle body 5 detected by the inclination angle sensor 6 exceeds a predetermined angle. Here, the predetermined angle is set differently depending on the vehicle type, and is set to 60 degrees in the present embodiment.
[0014]
Further, the electronic fuel injection device 8 has a fuel cutoff function that shuts off the supply of fuel to the engine 10 when the inclination angle of the vehicle body 5 becomes a predetermined angle (60 degrees) or more. The engine 10 drives a generator 11 via a belt, and the amount of power generation is supplied to the battery 12. When the amount of power generation is less than the load amount, the battery 12 functions as a power source and discharges, while the amount of power generation exceeds the load amount. In many cases, only the generator 11 serves as a power source, and the battery 12 is charged by the generator 11.
[0015]
Further, a hazard switch 14 is connected to the main switch 13 in series, and the hazard switch 14 and the electronic switch 9 are connected in parallel. When the rider turns on the main switch 13 and turns on the hazard switch 14, the hazard lamp 4 flashes.
[0016]
Next, the operation of the above embodiment will be described.
[0017]
FIG. 3 is a flowchart showing the operation of the hazard system 7. This flowchart is a processing procedure that automatically starts when the main switch 13 is turned on and the battery 12 functions as a power source.
[0018]
As shown in FIG. 3, the hazard system 7 reads the signal (data / information) of the inclination angle A of the vehicle body 5 detected by the inclination angle sensor 6 in step S1, and the vehicle body 5 falls due to an accident in step S2. When the inclination angle A of 5 is 60 degrees or more, the electronic switch 9 is turned on in step S3 to issue a command for forcibly blinking the hazard lamp 4. Thereby, the hazard lamp 4 blinks automatically and forcibly.
[0019]
If the inclination angle A of the vehicle body 5 is less than 60 degrees in step S2, the process returns to step S1 to read the signal (data / information) of the inclination angle A of the vehicle body 5. That is, the hazard system 7 always reads the signal of the inclination angle A of the vehicle body 5 until the inclination angle A of the vehicle body 5 reaches 60 degrees or more. The hazard lamp 4 stops blinking by turning off the main switch 13.
[0020]
Further, in the present embodiment, when the vehicle body 5 falls down due to an accident and the inclination angle A of the vehicle body 5 becomes 60 degrees or more, the fuel cutoff function in the electronic fuel injection device 8 is activated to supply fuel to the engine 10. To block.
[0021]
On the other hand, when the motorcycle 1 has failed and stopped, the rider may turn on the hazard switch 14 to cause the hazard lamp 4 to blink.
[0022]
As described above, according to the present embodiment, when the vehicle body 5 falls due to an accident and the inclination angle of the vehicle body 5 becomes 60 degrees or more, even if the rider is injured and the hazard switch 14 cannot be turned on. Since the hazard lamp 4 is automatically and forcibly blinked, the following vehicle can immediately detect an emergency due to a fall or accident. As a result, it is possible to avoid a collision with the vehicle body 5 that has fallen, and to prevent secondary accidents.
[0023]
In addition, according to the present embodiment, when the inclination angle of the vehicle body 5 is 60 degrees or more, the fuel cutoff function of the electronic fuel injection device 8 is activated, so that fuel leakage can be prevented in advance. .
[0024]
【The invention's effect】
