JPH1134731A - Moving body flood light obstacle irradiating system - Google Patents

Abstract

PURPOSE: To improve a course visibility at night by providing a subtracter which calculates a difference between a variable proportional to an obstacle position detected by an obstacle detector and the output of an angle displacement detector and provides it to a drive part as a control input. CONSTITUTION: When a flood light 8 is turned on, an obstacle in front of a moving body and a target are detected by an obstacle detector 1. This signal is provided to a normal/reverse turning gear 7 via an amplifier 2, an obstacle detector 3, a normal/reverse turning gear drive and vibration generator 4, a subtracter 5, and a normal/reverse turning gear drive controller 6. The normal/ reverse turning gear 7 is rotated by an angle proportional to the difference to be inputted in the subtracter 5 so that the light 8 is synchronized to the obstacle position to be rotated and so the irradiation direction is changed. The chance in the irradiation direction of the light 8 which is detected by the angle displacement detector 9 is fed to the subtracter 5 and controlled so as to set the difference to zero by a loop, and when it reaches zero, the power supplied to the normal/reverse tuning gear 7 becomes zero to stop the rotation of the normal/reverse turning gear 7.

[0002]

2. Description of the Related Art Conventional headlights for automobiles and trains are of a fixed type due to laws and regulations, and therefore do not have a turning device. Further, there is no device for automatically detecting and irradiating obstacles and target objects on other moving objects.

[0003]

Since the conventional headlights, auxiliary lights, rear lightings, and the like of the moving body are fixed as described above, the lighting of the moving body at night is difficult. There is a problem such as oversight when illuminating only directly in front of and behind the vehicle and manually turning the lighting direction of the lighting to control the moving body and the driver to find obstacles and check targets. However, when an illumination lamp having a wide irradiation angle is attached in advance, there is a problem that irradiation is not sufficiently performed to a distant place.

[0004]

According to the present invention, there is provided a moving body illumination lamp obstacle illuminating apparatus according to the present invention, comprising: a driving unit for changing the illumination direction of the illumination lamp; and an angular displacement detector for detecting a turning angular displacement of the illumination lamp. An angular displacement detector that detects an angular displacement, an obstacle detector that detects an obstacle or a target near the traveling direction of the moving object, and a variable proportional to an obstacle position detected by the obstacle detector. And a subtractor that calculates a difference amount from an output of the angular displacement detector and obtains the difference amount as an operation amount for the driving unit.

[0005]

According to the present invention, an automobile, a train, an aircraft, a ship,
Turning the lighting of moving objects such as cranes, motorcycles including motorbikes, and bicycles toward obstacles and targets,
The course visibility at night should be improved.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a mobile illuminating light obstacle illuminating apparatus according to the present invention. FIG. 1 is a diagram of an embodiment, and 1 is an obstacle detector configured by, for example, an infrared sensor that detects an obstacle or a target in the vicinity of the moving body in the traveling direction.
Reference numeral 2 denotes an amplifier for amplifying the output of the obstacle detector 1, reference numeral 3 denotes an obstacle determiner for specifying the direction of the signal of the obstacle amplified by the amplifier 2, and reference numeral 4 denotes the obstacle determined by the obstacle determiner 3. A forward / reverse rotation device drive signal generator 5 of the forward / reverse rotation device 7 for directing the illumination direction of the illumination lamp in the direction of the direction, and a variable 5 proportional to the obstacle position of the obstacle detector 1 and an output of the angular displacement detector 9. A subtractor 6 for calculating the difference, 6 is a forward / reverse rotation device drive control device for controlling the forward / reverse rotation device based on the drive signal of the forward / reverse rotation device adjusted by the subtractor 5, and 7 is a direction for irradiating the illumination lamp 8. A forward / reverse rotation device as a drive unit for changing the illumination, 8 is an illumination lamp, 9 is connected to a forward / reverse rotation axis of the illumination lamp 8 whose irradiation direction is controlled by the forward / reverse rotation device 7, and changes the angular displacement of the rotation angle. An angular displacement detector for detecting the angular displacement is transmitted to the subtractor 5.

When a moving body equipped with such a device is operated at night or at dusk with the illuminating lamp 8 turned on, an obstacle and a target in front of the moving body are detected by the obstacle detector 1. This signal is supplied to a forward / reverse rotation device 7 via an amplifier 2, an obstacle determiner 3, a forward / reverse rotation device drive vibration generator 4, a subtracter 5, and a forward / reverse rotation device drive controller 6. The forward / reverse rotation device 7 rotates by an angle proportional to the difference amount input to the subtracter 5, tunes the illumination lamp 8 to the obstacle position, turns the illumination lamp 8, and changes the irradiation direction. A change in the irradiation direction of the illumination lamp 8 is detected by an angular displacement detector 9 and given to a subtractor 5, which is controlled in this loop so that the difference amount becomes zero, and is supplied to a forward / reverse rotation device 7 when it becomes zero. Power also becomes zero, the rotation of the forward / reverse rotation device 7 stops,
When there is no obstacle in front of the moving body, the acceleration in the lateral direction decreases, so that the polarity of the output of the subtractor 5 is reversed, and the rotation of the forward / reverse rotation device 7 is also reversed.

The forward / reverse rotation device as a drive unit for changing the direction of irradiation of the illumination lamp may be driven by a motor or a rotational motion of a reaction force by a magnetic force as long as the device generates a rotational motion. .

Although an infrared sensor is described as an obstacle detector, an ultrasonic sensor, a millimeter wave sensor, or the like may be used as long as it can detect obstacles in front and behind.

In the description with reference to FIG. 1, the illuminating lamp 8 is always lit during night driving. However, when the obstacle detector 1 detects an obstacle, the illuminating lamp 8 is turned on and the illuminating lamp 8 is turned off. The light may be turned off.

In the description with reference to FIG. 1, the illuminating lamp 8 illuminates an obstacle detected by the obstacle detector 1, but it may illuminate an oncoming vehicle in an automobile or a train. In 3, irradiation may be performed in the forward traveling direction without obstacles.

[0012]

As described above, according to the present invention,
When operating vehicles such as cars, trains, aircraft, ships, cranes, motorcycles including motorbikes, and bicycles at dusk or at night, early detection can be achieved by illuminating obstacles and targets around the vehicles. This facilitates the operation of the mobile unit and enables the safe operation of the mobile unit.

[0013] In addition, since an object near the traveling direction of the moving object is illuminated, it is considered that the presence and the moving direction of the own vehicle can be indicated, and it is expected that attention is drawn to other moving objects and humans. it can.

[0014] In addition, if it is legally possible to mount the vehicle on a headlight for an automobile or a train, it is considered that the irradiation direction of the illumination light can be shifted from the oncoming vehicle, and the oncoming vehicle is dazzled. We can expect reduction of the.
