Description

[Detailed description of the invention] The present invention relates to a rear side obstacle warning device for a vehicle.
Obstacle warning system that detects obstacles such as vehicles in invisible areas at the rear of the vehicle that cannot be seen through outside mirrors, door mirrors, or inside mirrors when the driver is checking the front, and notifies the driver. Regarding.

First, the area that can be visually seen by the driver when facing forward will be explained using FIG. 1. For example, vehicle 1
The area that the driver can visually check is the direct view area A.
, an outside mirror visible region B that can be seen with the left and right outside mirrors, and an inside mirror visible region C that can be seen with the inside mirror. Therefore, when the driver faces forward, he cannot visually see the region D on the rear side of the vehicle. The area D is hereinafter referred to as an invisible area. by the way,
The visibility of the vehicle 1 is secured through direct visibility and through the inside and outside mirrors, so when changing lanes, turning right, turning left, etc., the presence or absence of obstacles such as vehicles within the invisible area D is recognized. To do so, the driver must turn around and look directly behind him, which is extremely dangerous as he cannot check the road ahead during that time. Furthermore, if there is a passenger in the vehicle, obstacles in the invisible area D may be hidden behind the passenger and may be overlooked, and if the side windows are fogged up, obstacles in the invisible area D may be overlooked. may not be directly visible.

Recognizing obstacles in the invisible area D by direct visual recognition as described above poses a problem that involves great danger when changing lanes, turning right, or turning left. This problem also occurs in vehicles equipped with door mirrors.

The purpose of this invention is to solve the above-mentioned problems,
Detects obstacles intruding into areas at the rear of the vehicle that cannot be seen with the outside mirror, door mirror, or inside mirror, and detects obstacles that can be seen by the driver while facing forward, e.g. An object of the present invention is to provide a rear-side obstacle warning device for a vehicle that allows safe lane changes, right turns, left turns, etc. by displaying the information on the outside mirror.

In order to achieve this purpose, the vehicle rear side obstacle warning device of the present invention is provided with a detector and its control device in the taillight to detect when an obstacle enters the invisible area, and to detect the obstacle. The system is characterized in that a warning is given to the driver by emitting color light from a display provided in the outside mirror.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. In FIGS. 2 to 4, 2 indicates a tail light (combination lamp) on the right side of the vehicle, and in FIG. 5, 3 indicates an outside mirror on the right side of the vehicle. The taillight 2 is equipped with a detector 4 that can detect obstacles such as vehicles entering the invisible area D shown in FIG.
Control equipment (amplification, detection, etc.) 5 for the detector 4 is built-in. Further, an indicator 6 is installed on the stay 3A of the outside mirror 3, and emits color light or flashes color light when an obstacle is detected by the detector 4.

The detector 4 includes a transmitter 4A and a receiver 4B, and can detect an obstacle by reflecting ultrasonic waves or electromagnetic waves emitted from the transmitter 4A on the obstacle and receiving it at the receiver 4B. It's becoming like that. The transmitter 4A is arranged inside the vehicle side surface 2A of the taillight 2 so that the ultrasonic waves or electromagnetic waves can be transmitted to the side of the vehicle substantially perpendicular to the direction of travel of the vehicle.

Further, the receiver 4B is arranged inside the vehicle side surface 2A of the taillight 2 so as to be able to most efficiently receive ultrasonic waves or electromagnetic waves reflected and returned from obstacles.

Although not shown, a detector and a control device are also built into the left taillight of the vehicle in the same manner as described above, and a display is also installed in the stay of the left outside mirror.

In FIG. 6, the shaded area E indicates the detector 4
The detection area is shown in the figure.

However, in the rear and side obstacle warning system for a vehicle according to the present invention, if another vehicle 10 enters the invisible area D of the vehicle 1 while the vehicle 1 is running as shown in FIG. Vehicle 10 is detector 4
is detected, and the display 6 of the outside mirror 3
emits color light (or flashes color light), so the driver can recognize that the vehicle 10 is intruding into the invisible area D just by looking at the display 6, and thereby change lanes. , turn right or left safely.

In the present invention, the installation locations of the detector 4 and the display 6 are not limited to those in the above-mentioned embodiments, and the detector 4 is installed at its transmitter 4A as shown in FIGS. 7 and 9. The receiver 4B may also be arranged on the rim 2B side of the vehicle side surface 2A of the taillight 2 and attached to the rim 2B.

Further, the display 6 may be installed on the body portion 7A of the inside mirror 7 as shown in FIG. 9, or in the case of a vehicle with a door mirror, it may be installed on the body portion 8A of the door mirror 8 as shown in FIG. Good too. Further, although not particularly shown, a display device may be installed on the instrument panel in the driver's cab. In addition, when the display device 6 is installed on the inside mirror 7 as shown in FIG. 9, the display device emits color light (or flashes color light emission) when an obstacle that has entered the invisible area on the left side of the vehicle is detected. 6 and a display device 6 that emits color light when an obstacle entering the right side invisible area of the vehicle is detected are attached to the left and right positions of the body portion 7A. In addition, when the display device 6 is installed on the inside mirror 7, the use of a display device that combines color light emission (or color light flashing) and an audible alarm can cause visual and hearing impairments for the driver. Can convey information about property intrusion.

As explained above, according to the present invention, an obstacle that has entered the invisible area on the rear side of the vehicle is detected,
Since this detection can be displayed in a location where the driver can see it while facing forward, it is possible to safely change lanes, turn right or left, etc.
