Description

[Detailed explanation of the invention] This invention is designed so that when a vehicle turns on the turn signal switch and changes direction at an intersection while driving at night, the cornering lamp is turned on to illuminate the side of the vehicle on the side of the direction change. The present invention relates to an operating circuit for a cornering lamp.

Generally, when a large vehicle turns left or right, the trajectory of the rear wheels wraps inward from the trajectory of the front wheels, resulting in frequent collisions and, in the worst case, can result in personal injury. This tendency is particularly serious when driving at night, as visibility is reduced. Therefore, as one measure to prevent accidents, a method has been proposed in which a cornering lamp provided on the left side of the vehicle body is turned on when a turn signal switch is turned on, for example, to the left, with the aim of improving visibility. According to this system, when turning left or right at night, the cornering lamps are turned on, so the driver can see the brightness near the side of the vehicle on the side where he or she is turning the steering wheel, so he or she can be aware of the presence or absence of motorcycles or other vehicles and the risk of collision. Since it is possible to confirm the following, it is possible to prevent accidents caused by unknown factors. However, if the cornering lamps are turned on every time the steering wheel is turned, even during the day, power consumption increases, and there is a risk that the battery's power storage capacity will decrease, especially in vehicles that mainly drive in urban areas. Additionally, due to legal regulations with this system, cornering lamps cannot be turned on when the hazard switch is turned on.

The present invention was developed in view of the above circumstances, and aims to provide a cornering lamp operating circuit that satisfies the above-mentioned legal regulations, improves visibility, and reduces power consumption.

Hereinafter, one embodiment shown in the drawings will be described in detail.

In the figure, the left side of the vehicle is equipped with a front turn lamp FT ₁ at the front, a front side turn lamp FST ₁ at the front edge, a side turn lamp ST ₁ at the side, and a rear turn lamp RT ₁ at the rear. , when the turn signal switch 2 in the combination switch 1 is turned on to the left L, the signal current i ₁ is applied to the relay 4 in the relay fuse box 3.
is activated, a drive current _i10 is applied, and the lamps on the left side are lit all at once. In this case, an interrupter (not shown) causes intermittent lighting. Similarly, when the turn signal switch 2 is turned on to the right direction R, the lamps FT ₂ , FST ₂ , and ST ₂ on the right side of the vehicle light up intermittently all at once. The combination switch 1 is also provided with a hazard switch 5, and when this switch 5 is turned on, the left and right signal currents are
As i ₁ and i ₂ flow, orange lamps (not shown) provided on both sides of the vehicle light up intermittently all at once.
Further, when a tail lamp switch 6 as a tail lamp intermittent means in the combination switch 1 is turned on, a drive current i ₃ flows through a tail lamp relay 7 and the tail lamps T ₁ and T ₂ are turned on.

Now, the feature of the present invention is that the above circuit is equipped with cornering lamps CL and CR on the left and right sides of the vehicle body, and left and right power relays 8 are provided to turn on these lamps CL and CR. The power relay 8 consists of a left cornering lamp relay 8L and a right cornering relay 8R, each having a two-pole, double-throw switch and an excitation coil. The coils 9 and 10 are connected at one end to the turn signal switch 2 and at the other end to the power source E, and are energized when the left and right turn signal switches 2 are alternately switched on. On the other hand, the lamps CL and CR are connected to the power supply via the normally open contacts 13 and 14 of the cornering lamp relays 8L and 8R, the normally closed contacts 12 and 11 of the other cornering lamp relay 8R and 8L, and the tail lamp relay 7. ing. Therefore, simply turning on the tail lamp switch 6 will cause the coils 9,
Since 10 is not excited, cornering lamp CL,
CR does not light up.

Now, if the turn signal switch 2 is turned on, for example, to the left L while the tail lamp switch 6 is turned on, the signal current i ₁ flows and the lamps FT ₁ , FST ₁ , ST ₁ and RT ₁ on the left side of the vehicle light up intermittently. .
On the other hand, when signal current i ₁ and signal current i ₁₁ flow, left cornering lamp relay 8L is energized and contact 1
3 is closed, the drive current _i3 passes through the normally closed contact 12 of the relay 8R and the closed normally open contact 13 of the relay 8L, and lights up the left cornering lamp CL. Similarly, if the turn signal switch 2 is turned on to the right R, the right cornering lamp CR lights up.
Even if the tail lamp switch 6 is turned off and the turn signal switch 2 is turned on, the cornering lamps CL and CR do not light up because the drive current _i3 does not flow through them.

Next, when the hazard switch 5 is turned on while the tail lamp switch 6 is left on, signal currents i ₁ , i ₂ and signal currents i ₁₁ , i ₂₂ flow, and both cornering relays 8L, 8R are excited. Contact 1
1 and 12 are both open, drive current _i3 does not flow, and cornering lamps CL and CR do not light up.

As described above, the present invention has a configuration in which the cornering lamps are turned on when the turn signal switch and tail lamp switch are on and the hazard switch is off, so when driving at night, the tail lamp switch is turned on and the turn signal switch is turned on, for example, to the left. When turned on, the cornering lamp installed on the left side of the car lights up, improving visibility for the driver as the side of the car on the side where the steering wheel is turned is bright, and the tail lamp switch can be turned off during the day. This allows the cornering lamps to save energy by not turning them on. Furthermore, when the hazard switch is turned on, the power relay becomes inactive and the cornering lamps do not light up, so it also has the effect of meeting legal regulations.
