JPS6099737A - Blinker control device for cornering lamp - Google Patents

Abstract

PURPOSE:To aim at holding a state of lightingness until the completion of cornering as well as economizing in electric power consumption, by lighting a cornering lamp as long as a portion for a shorter part in operating times of a steering turn detecting device and a timer, on the basis of off-operation in a turn signal switch. CONSTITUTION:During a drive with a light switch 10 turned to a small lamp position S at dusk, if a turn signal switch 11a is operated to turn on to the left, a turn signal lamp 3b at the left blinks and simultaneously a cornering lamp switch 11b is operated to turn on to the left as well, thus a cornering lamp 1b at the left is lighted. Hereat, in the case where such an easy turning state as being unnecessary to light the lamp 1b after curving the corner, a state of lighting preservation is set free after a specified period of time since the switch 11a has turned off. In addition, when a car enters a straight-drive state immediately after curving the corner, a state of lighting preservation in the lamp 1b is set free when the steering 15 comes to a neutral position. With this constitution, wasteful lighting is checked and electric power consumption is thus economizable.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a blinking control device for a cornering lamp that illuminates the front side of a vehicle body in the direction of the turn when the vehicle is turning.

(b) Background of the technology In general, the headlights of automobiles are used to ensure the forward visibility of the automobile at night, so the illumination of the front and sides of the automobile is not very common. .

For this reason, when the vehicle turns around a sharp corner, it may be difficult to accurately determine the state of the corner depending on the headlights. Therefore, in recent years, the analogy is
As shown in the figure, a so-called cornering lamp 1f is provided on the front side portions of the left and right front fenders 2, and when the car turns, the cornering lamp 1 in the turning direction is turned on, so that the corner of the turn is clear.

It was proposed that the field of view should be secured.

(e) Prior Art and Problems Conventionally, as a device for controlling the blinking of the cornering lamp 1, there is, for example, the one shown in "Mandal-Cheleghat Structure and Maintenance (October 1977 issue), p. 278". . As shown in FIG. 2, this means that the turn signal switch 11a is turned to the right (or left)
When K is turned on, the right (
The right (or left) turn signal lamp 3a (3b) flashes, and power is supplied to the right (or left) cornering lamp 1a (1b) via the cornering lamp switch 11b which becomes the right (or left) main state. , the cornering lamp 1a (1b) is turned on.

However, the cornering lamp 1a (
In the blinking control device Ib), the power supply to the cornering lamp 1a (Ib) and its cut-off are controlled by a cornering lamp switch 11b that is linked to the on/on operation of the turn signal switch 11a. Therefore, when the car turns around the corner, if the turn signal switch 11a is intentionally turned off by the return operation of the steering wheel in the middle of the turn, the car will still completely turn the corner. Even though the cornering lamp switch 11b is not turned on, the cornering lamp switch 11b is turned off and the cornering lamp Ia is turned on.
There was a problem where (Ib) went out.

Therefore, “Animei Association Public Technical Report: Public Technical Number 83-3270
As shown in FIG. 1, even after the cornering lamp switch 11b is turned off by the timer, the cornering lamp 1 is still turned on for the time set in the timer.
It is conceivable to keep lighting of a(1b).

However, in order to ensure visibility to the sides of the vehicle body in the direction of the turn during a turn even under rough road conditions, the time set for the above timer must be set to a relatively long time (for example, 3 to 5 seconds). No. Therefore, even if the cornering lamp 1a (lb) is turned on before the set time elapses, especially when turning at right angles to the driving direction while driving in the city, the cornering lamp 1a (lb) remains lit and the vanteri power supply is turned on. This causes an oily problem in which labor costs are incurred.

(d) Purpose of "Emitting" The present invention has been made in view of the above, and it is possible to maintain the lighting state of the cornering lamp until the automobile has completely turned the P-angle, and to turn on the cornering lamp when the cornering lamp is turned off or lying down. The present invention relates to a cornering lamp blinking control device that prevents the lighting of cornering lamps.

(e) Structure of the Invention In order to achieve this object, the present invention provides a switch that is provided on both sides of the M portion of the vehicle body based on the operation of a switch means that is linked to the on/off operation of the right or left turn signal switch. A cornering lamp blinking control device configured to blink a right or left cornering lamp includes a steering rotation detection means for detecting that the steering wheel is in a state exceeding a predetermined steering angle, and the turn signal switch. a timer means for detecting that a predetermined period of time has elapsed since the turn signal switch was turned off;
The five cornering horns are kept lit only during the time when the steering rotation detection means is in the detection operation or until the timer means detects the passage of time, whichever is shorter. The lamp is provided with lighting holding means.

(f) Embodiments of the invention Hereinafter, embodiments of the invention will be described based on the drawings. Third
The figure is a circuit diagram showing an example of a blinking control device according to the present invention. In the same figure, 10 is the same as in the case shown in FIG.
11 is a switch unit consisting of a turn signal switch 11a and a cornering lamp switch 11b that operates on and off in conjunction with the turn signal switch 11a. By turning on the right (or left) of the turn signal switch 11a, the Vantelly power supply B is supplied to the right (or left) turn signal lamp 3a (3b) via the franchise unit 12, and the light Cornering lamp switch 11 linked to the turn signal switch 11a when the switch 10 is in the small lamp position (S) or the headlight position (6)
By turning on the right (or 7i) of b, the Sivanteri power supply B is supplied to the right (or 7i,) cornering lamp 1a (Ib).

13 is a rotation detector that detects that the steering wheel 15 is turning from the neutral position of zero steering angle to the stone (or left); 14 is a rotation detector 13 that detects when the steering wheel 15
This holding circuit 14 is a holding circuit that maintains the power supply state to the cornering lamp Ia (Ib) when detecting the turning state to the right (or left) of the cornering lamp 1a. It consists of a relay 14a for maintaining the power supply state and a relay 14b for maintaining the power supply state for the left cornering rung 1b.

Then, when the rotation detector 13 detects the right (or left) rotation state of the steering wheel 15, the relay 14a (
The coil 14b) is grounded via the relay timer circuit 16, and the coil is energized, and the relay contact closes, causing the power supply via the seat switch 10 to be turned on via the relay contact to turn on the cornering lamp. 1a (1b)
It is becoming more and more supplied.

The timer circuit 16 must be set in advance for a certain period of time (for example, 3 seconds to 5 seconds), and the cornering lamp switch 11b
Relay 14 is turned off after [Iff] at the above setting after is turned off.
This is to cut off the ground path from a or 14b to the rotation detector 13.

Here, the specific number 4 (41) of the rotation detection circuit 13 is as shown in FIG. 21, the rack 22 becomes negative, and the electrode piece 23a is connected to the coil of the relay 14a through the timer circuit 16 in FIG. When the steering wheel 15 is in a neutral position with zero steering angle, the rank 22 is located at an intermediate position between the electrode pieces 23a and 23b.

Then, when the steering wheel 15 is rotated to the right (or left), the shaft 22 is moved to the right (or left) by the rotation of the pinion 21, and the rank 22 and the electrode piece 23a (
23b), this rank 22 and the electrode piece 23 are in contact with each other.
a (23b) and the timer circuit 16 to the coil of the receiver 14a (14b).

Next, the operation will be explained using an example in which a car turns left. For example, if you turn on the turn signal switch lla' to the left while driving with the light switch 10 set to the small lamp position (S) at dusk, the left turn signal lamp 3b will flash and the cornering lamp switch 11b will turn on to the left. When activated, the left cornering lamp 1b lights up. In this state, the steering wheel 15 rotates to the left, and the steering wheel 15 is returned while the vehicle is turning to the left. In addition, if a gentle left turn is made before the steering wheel 15 reaches the neutral position, even if the turn signal switch 11a is automatically turned off by returning the steering wheel 15, the steering wheel 15 will not turn left. In the dynamic state J, the welding state between the rank 22 in the rotation detector 13 and the electrode piece 23b continues, and the relay contact of the relay 14b maintains the closed state, so that the lighting state of the cornering rung 1a is changed. Retained. And the turn signal switch Il
The setting of the timer circuit 16 from the time of the off operation of f1.a. After 7 seconds, the timer circuit 16 cuts off the ground path from the coil of the relay 14b to the rotation detector 13, and the cornering lug 1b turns off.

On the other hand, when the cornering lug 1b is turned on by turning on the turn signal switch 11a, for example, when turning a sharp corner at a P angle, the turn signal switch 11a is turned on by the return operation of the steering wheel 150 during the turn. If the steering wheel 15 reaches the neutral position before the time set in the timer circuit 16 elapses after the turning off operation, the cornering lamp 1b will turn off at that point.

In other words, in this embodiment, if a gentle turning condition that does not require lighting by the cornering lamp 1a (lb) continues after the turn has turned nine corners, the turn signal switch lla is turned off after a certain period of time. If the state where the cornering lamp 1a (lb) is kept on is released and the vehicle turns straight ahead after turning the P angle, the cornering lamp 1a (1b) is kept on when the steering wheel 15 is in the neutral position. The condition will now be removed.

In the above embodiment, the rotation detector 13 is configured as shown in FIG. 4, but it may be configured as shown in FIG. 5, for example.

This includes a gear 31 that is coaxial with the rotating shaft 20 of the steering wheel 15, an internal gear 32 that meshes with the gear 31, contacts a grounded electrode 33 at its outer periphery, and further forms a convex portion 32a. It is provided on the outer periphery of the internal gear 32 and consists of an electrode 34a connected to the coil of the relay 14a in FIG. 3, and an electrode 34b connected to the coil of the relay 14b. When the steering link 15 is in the neutral position, the convex portion 32a of the internal gear 32 is positioned midway between the electrodes 32a and 32b, and when the steering wheel 15 is rotated to the right (or left), the internal gear The convex portion 32a of the gear 32 contacts the electrode 34a (34b), and the electrode 33, the internal gear 32, and the electrode 34a (34b)
) and further via the timer circuit 16, the coil of the relay 14a (14b) in FIG.

Further, in the above embodiment, the cornering lamp 1a (lb
) The earth path from the relay 14a (14b) that keeps the lights on to the rotation detector 13 is cut off by the timer circuit 16, but the present invention is not limited to this, and for example, when the turn signal switch 11a is turned off, after,
The cornering lamp Ia is activated for the time set by the timer circuit 16.
(Ib) is kept lit, and the rotation detector 1
37559u is the upper i when the neutral position is detected.
It may be configured to release the lighting state of the own cornering lamp Ia (lb).

Effects of the Invention As explained above, according to the present invention, when the turn signal switch is turned on, the ignited cornering lamp rotates the steering wheel and returns to the predetermined steering angle Vr-. The turn signal switch is turned off and the turn signal switch is turned off and the turn signal switch is turned off for a predetermined period of time, whichever comes first. It is possible to maintain the lighting state of the cornering lamp when the music is 9 and also prevent unnecessary lighting even when the vehicle is parked in the steering state, such as when parking in a garage or parallel parking.
