Definitions
- the invention relates to a method and a device warning of road users for a rail vehicle by means of sound or light signals.
- Rail vehicles are equipped with acoustic warning devices, such as horns, horns, bells, etc. by means of which other road users can be warned. Likewise, they are equipped with optical lighting devices (three-light
- Warning devices are operated by the driver and are characterized in part, especially in full tracks by very high volume. This high volume leads to high sound entry into the driver's compartment, which in extreme cases can lead to conflicts with relevant occupational safety laws. Furthermore, these warning devices have a very little bundled Schallabstrahl characterizing, whereby a majority of the sound energy is not directed to the target and thereby the effective range of the warning device is reduced. In vehicles for traffic within the urban area significantly quieter warning devices are provided, such as bells or ringing at Trams. Those submitted by these institutions
- Pedestrian traffic (trams in pedestrian areas) requires permanently necessary concentration.
- the invention is therefore based on the object of specifying a method and a device for warning road users for a rail vehicle by means of sound or light signals, which causes an automatic emission of sound or light signals.
- the invention can be used automatically
- Rail vehicles are used, which drive on a non-separate from the rest of traffic or not intersection-free rail network.
- the invention comprises a device for warning road users for a rail vehicle by optical and acoustic signaling devices, wherein sensors are provided, which for the detection of
- Position data of other road users are set up and which transmit them to a control device, wherein the control means comprises computing means for determining an at least two-stage collision probability and a warning level for each other road users from these position data and wherein the control means for controlling the optical and acoustic Signaling devices comprises and the optical and acoustic signaling devices in
- sensors are provided, which the
- optical cameras for visible light for example, optical cameras for visible light
- Thermal imaging cameras infrared cameras
- laser sensors laser sensors
- Rail vehicle can be determined because laser sensors can determine a three-dimensional image of the vehicle environment.
- Control device an at least two-stage
- Collision probability calculated. For example, the collision probability of an object located directly on the track at a great distance, which has no airspeed of its own, is 100%; however, for an object just leaving the driveway in the immediate vicinity, the collision probability is 0%.
- Collision probability on. is a classification of the detected other road users in certain
- the control device continuously determines a respective collision probability for the additional road users detected by the sensors and determines therefrom as well as from the optional categorization each an adequate warning degree.
- Each alert level corresponds to a particular acoustic signal alone or in combination with a particular optical signal.
- Signaling devices designed radiated signals in their intensity or their waveform or their direction of emission as a function of the respective degree of warning. For example, for the warning of a person in
- Light cones can be changed automatically
- variable focal length of the lamp associated with the lens For example, by means of a presettable by the control device variable focal length of the lamp associated with the lens.
- a preferred embodiment of the invention provides to emit the acoustic signals by means of strong focusing parametric ultrasound speakers.
- These loudspeakers make it possible to radiate sound extremely concentrated in the audible frequency range, with the sound itself being generated by means of ultrasound.
- the specific design of these speakers makes it possible to perceive the sound event only from a certain distance from the sound source, but not in the immediate vicinity of the sound source. In such a way, the sound entry into the reduced
- control device determines the respectively required setting from the position data of the other road user
- Movement device can also be a plurality of
- Ultrasonic speakers are provided, each for the sonication of a certain angular range around the
- Vehicle front are designed.
- the control device initiates the signal to be reproduced those ultrasound loudspeakers in whose emission range the other road user to be warned was recognized.
- control device with an interface to a
- the braking is triggered by the control device when the collision probability with another
- a preferred embodiment of the invention provides to provide the control device with an interface to an input-output device.
- commands can be transmitted to the control device via this interface, which cause the manual triggering of a signal.
- the interface for optical representation of the positions of the other via this interface
- the rail vehicle may be equipped with an output device by means of which the vehicle driver can be represented by the detected further road users.
- the vehicle driver can be represented by the detected further road users.
- screens, inserts in a windscreen (head-up display) or data glasses can be used. The driver is thus the other detected by the sensors and the control device and possibly classified
- Control device by time averaging
- the advantage can be achieved to be able to realize a warning intensity adapted to the respective environment, in which the sound signal can be reliably heard, but does not represent excessive annoyance. For example, in quiet environments, especially too
- Fig.2 means for warning road users.
- FIG. 1 shows, by way of example and schematically, a rail vehicle and other road users. It is shown the principle underlying the invention.
- a rail vehicle 1 runs on a route on which is to be expected with passenger traffic, such as a tram in one
- Road users such as motor vehicles application.
- FIG. 2 shows, by way of example and schematically, a device for warning road users. It is based on one
- Control device 5 comprises. To detect more
- Road users 4 are provided by way of example with a camera 7 and a sensor 6, which transmit their respective data to the control device 5.
- the warning of the other road users takes place via two acoustic signals
- Signaling devices 2 can also be embodied as parametric loudspeakers, with an emission direction being transmitted by the control device 5 in addition to the audio signal to be reproduced.
- an input device 11th For interaction with a driver is an input device 11th
- an output device 12 is provided, which displays the information transmitted to it by the control device 5 optically and / or acoustically to the vehicle driver.
- a microphone 10 is connected to the control device 5 via which the driver voice announcements over the
- the control device 5 can emit acoustic signaling devices 2.
- the control device 5 comprises a latch 8, which via the acoustic and optical
