METHOD AND SYSTEM FOR WARNING FOR VULNERABLE ROAD USERS IN CONNECTION TO A NON-MOVING VEHICLE
TECHNICAL FIELD
The invention relates to a method for warning for vulnerable road users in
connection to a non-moving vehicle according to the preamble of claim 1. The invention relates to a system for warning for vulnerable road users in connection to a non-moving vehicle. The invention also relates to a vehicle. The invention in addition relates to a computer program and a computer
program product.
BACKGROUND ART
A lot of accidents occur when pedestrians walk in front of a vehicle, e.g. a bus, intending to cross the road as it is difficult for the driver of an approaching vehicle to see the person.
In order to prevent such accidents some buses are equipped with warning
systems.
US20110163868 discloses a warning system mounted on a bus comprising detecting means for detecting an object such as a person, and signalling means connected to the detection mean, said detection means being arrange
to remotely detect an object in the vicinity of the vehicle.
The detection means in US20110163868 is connected to signalling means to automatically emit a signal that is detectable from a side of the vehicle so as to warn an oncoming vehicle.
OBJECTS OF THE INVENTION
An object of the present invention is to provide a method for warning for vulnerable road users in connection to a non-moving vehicle which further reduces risk for accident involving the vulnerable road user.
Another object of the present invention is to provide a system for which for warning for vulnerable road users in connection to a non-moving vehicle which further reduces risk for accident involving the vulnerable road user.
SUMMARY OF THE INVENTION
These and other objects, apparent from the following description, are
achieved by a method, a system, a vehicle, a computer program and a computer program product, which are of the type stated by way of introduction and which in addition exhibits the features recited in the characterising clause of the appended independent claims. Preferred embodiments of the method and the system are defined in appended
dependent claims.
Specifically an object of the invention is achieved by a method for warning for vulnerable road users in connection to a non-moving vehicle comprising the steps of detecting a vulnerable road user object in connection to a vehicle; detecting another vehicle approaching said non-moving vehicle; and
activating a warning of the existence of the detected object, said warning
being directed to said approaching vehicle. The step of activating a warning directed to said approaching vehicle comprises the steps of: establishing contact with the approaching vehicle within a vehicle-to-vehicle communication arrangement; and communicating information about said
object to said approaching vehicle. Hereby the risk for accident involving the
vulnerable road user such as a pedestrian is reduced in that the approaching vehicle communicates with the non-moving vehicle and can take measures in order to avoid an accident.
According to an embodiment of the method the step of activating a warning of the existence of the detected vulnerable road user object comprises the step of generating a projection on the ground by illumination. Hereby the vulnerable road user and/or the driver of the approaching vehicle will be
informed in an efficient way about the approaching vehicle further reducing
the risk of an accident.
According to an embodiment of the method the warning comprising the step of generating a projection on the ground by illumination directed to the vulnerable road user object and/or the approaching vehicle. Hereby the
vulnerable road user and/or the driver of the approaching vehicle will be
informed in an efficient way about the approaching vehicle further reducing the risk of an accident.
According to an embodiment of the method the step of detecting said object comprises the step of detecting direction of movement of the object relative
to the non-moving vehicle. By having information about the direction of
movement of the object, i.e. the vulnerable road user object, unnecessary activation of warning can be avoided. Thus according to a variant a warning is only activated if the object is moving in the direction towards the road on which the approaching vehicle is travelling or if the object is standing still and
not if the object is moving in another direction away from the danger.
According to an embodiment of the method the step of activating said warning directed to the approaching vehicle and/or the vulnerable road user object is effected depending on the direction of the movement of the object. Hereby unnecessary activation of warning can be avoided. Thus according to
a variant a warning is only activated if the object is moving in the direction
towards the road on which the approaching vehicle is travelling or if the object is standing still and not if the object is moving in another direction away from the danger.
According to an embodiment of the method the step of detecting said object comprises the step of determining the position of said object relative to said non-moving vehicle; and wherein the step of communicating information about said object to said approaching vehicle comprises the step of
communicating information about said position. Hereby the approaching
vehicle will have information of not only the risk of the object but also the location of the object and thus the risk of an accident may be further reduced, thus improving safety.
According to an embodiment the method comprises the steps of: determining
whether the vulnerable road user object and/or the approaching vehicle has perceived the warning by means of the generated projection on the ground; and, if not, escalating the warning. Hereby the risk of accident will be further reduced.
Specifically an object of the invention is achieved by a system for warning for
vulnerable road users in connection to a non-moving vehicle according to
independent claim 8.
The system further comprises the embodiments according to claims 9-14.
The system according to the invention has the advantages according to the corresponding method claims.

may be in connection to a non-moving vehicle and may cause an accident with an approaching vehicle such as a pedestrian, an animal such as a dog, a person in a wheel chair, a baby carriage, or the like. The term "vulnerable road user object" also refers to a vulnerable road user. The term "vulnerable road user" also refers to a vulnerable road user object.
Hereinafter the term "vehicle-to-vehicle communication arrangement" refers
to any wireless communication arrangement between a non-moving vehicle and a vehicle approaching the non-moving vehicle such as for example a radio or microwave link, Wi-Fi, Bluetooth, or the like.

When data is received on data port 599 it is temporarily stored in second memory portion 540. When the received input data has been temporarily
stored, data processing device 510 is set up to perform execution of code in
a manner described above. The signals received on data port 599 can be used by apparatus 500 for detecting a vulnerable road user object in connection to a vehicle. The signals received on data port 599 can be used by apparatus 500 for detecting another vehicle approaching said non-moving
vehicle. The signals received on data port 599 can be used by apparatus 500 for activating a warning of the existence of the detected object, said warning being directed to said approaching vehicle. The signals used by apparatus 500 for activating a warning comprises signals used by apparatus 500 for establishing contact with the approaching vehicle within a vehicle-to-vehicle
communication arrangement, and signals used by apparatus 500 for communicating information about said object to said approaching vehicle.
Parts of the methods described herein can be performed by apparatus 500 by means of data processing device 510 running the program stored in separate memory 560 or read/write memory 550. When apparatus 500 runs 30 the program, parts of the methods described herein are executed.
The foregoing description of the preferred embodiments of the present invention has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations will be apparent to
practitioners skilled in the art. The embodiments were chosen and described
in order to best explain the principles of the invention and its practical applications, thereby enabling others skilled in the art to understand the invention for various embodiments and with the various modifications as are suited to the particular use contemplated.
