Benefits of technology

[0007] It is therefore an object of the present invention to provide an information providing device which enables a driver to quickly react to a dangerous object.
[0010] Thus, the driver watching the heading direction notices the movement of the visual information and the sight line of the driver is led to the detected object by following the movement. Consequently, this helps prevent a delay in movement of the sight line or an oversight of the dangerous object.

Problems solved by technology

In addition, the device projects the spotlight only when it detects a dangerous object.
Therefore, the driver possibly has difficulty in immediately reacting to the spotlight which comes up at an unexpected position.
Moreover, a sight line of the driver and a heading direction of the vehicle are almost the same; therefore, the driver possibly fails to recognize the spotlight if the spotlight deviates from the heading direction.
Thus, using the conventional device, the driver sometimes has difficulty in recognizing a dangerous object even in a case where the driver needs to react against the dangerous object as quickly as possible.

Embodiment Construction

[0018] As shown in FIG. 1, an information providing device 100 mounted in a subject vehicle includes surrounding information detectors 10, driving operation state detectors 20, vehicle running state detectors 30, a controller 40, and a laser projection device 50.

[0019] The surrounding information detectors 10 include a laser or radar sensor, an image sensor, an ultrasonic sensor, and a navigation device. Using the detectors 10, the controller 40 detects characteristics of an object located outside the vehicle, specifically, frontward, sideward, and rearward of the vehicle. The detected characteristics of the object include, with respect to the object, a kind, a position, a heading direction, or a relative velocity relative to the vehicle. The kind of the object is, for example, another vehicle (further, a passenger automobile, a truck, a two-wheeled motorcycle, or the like), a pedestrian, a traffic control device, a road traffic sign, or a lane marker or a border between lanes on a...

Abstract

An information providing device provided in a vehicle includes an object detecting unit for detecting an object outside the vehicle; a providing unit for providing, outside of the vehicle, visual information which is visually perceptible; and a controlling unit for controlling the providing unit. The providing unit is usually caused to provide the visual information to indicate a heading direction of the vehicle. In contrast, when the detected object is determined to include a danger to advancement of the vehicle or an indication of stopping the vehicle, the providing unit is caused to then move the visual information to indicate a direction towards the detected object.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is based on and incorporates herein by reference Japanese patent application No. 2004-312849 filed on Oct. 27, 2004. FIELD OF THE INVENTION [0002] The present invention relates to an information providing device for a vehicle. BACKGROUND OF THE INVEHTION [0003] In JP-H06-255399-A, a conventional device is described which warns a vehicle's driver of an dangerous object by illuminating the dangerous object using a spotlight or by projecting a warning sign to a position which is on the windshield of the vehicle and corresponds to a position of the dangerous object. [0004] When the warning sign is shown on the windshield, the driver moves his / her sight line to the warning sign and adjusts his / her focus to the warning sign on the windshield to notice presence of the dangerous object. Subsequently, the driver adjusts his / her focus from the windshield to the dangerous object itself to estimate its distance from the vehicle. Thu...
