Definitions
- This invention relates to a vehicle impact warning device for installation in a motor vehicle, comprising a deceleration sensor through which delays directed approximately parallel to the road surface can be detected and to a switch activatable therefrom.
- warning devices will be set up at a certain distance in front of the scene of the accident and / or police officers will be posted to warn the following passengers.
- the accident information stored in this manner can be called up by suitable radio receivers as a voice signal and / or by navigation devices set up for this purpose as text information on a display.
- the object of the invention is to provide a device that is installed in the motor vehicle, and detects the occurrence of an impact at the earliest possible time and all in the same direction and with an adjustable, maximum distance behind the accident vehicle driving, other vehicles warns. It is thought of distances of the order of a few kilometers, so that the accident vehicle is located outside the audible or audible range.
- the warning should also be able to be passed on if a line of sight is restricted or interrupted by darkness, rain, snow, fog or other adverse weather conditions.
- the warning should also be given visually and acoustically.
- the device should automatically pass on a received warning to other, similar devices.
- a simple design with known components is said to mean a low price and a high degree of reliability and thus a very large one
- the invention proposes a vehicle collision warning consisting of a deceleration sensor and a switch activatable therefrom, which is characterized in that
- a first electromagnetic radio warning signal and a warning signal as a visual warning signal and / or an acoustic warning signal can be triggered.
- Variants are also known in which a ball is held in a specific position by a magnetic field and is moved out of the zero point in proportion to the delay by a certain distance.
- deceleration sensors typically detect a threshold of the order of 3 to 5 g.
- the message of exceeding this limit is triggered either by the fact that the mass itself makes contact or that the mass changes an electrical capacitance or inductance, which is evaluated with a suitable electronic circuit.
- crash sensors are designed to activate an electrical contact when reaching the limit value, either directly or via a power semiconductor, with which additional consumers can be switched on.
- This switch can be designed as an electronic switch, that is, as a second, larger power semiconductor.
- all the usual forms of relays are also possible.
- the switch closes and activates. Fourth thereby both a warning signal and a radio transmitter.
- Visual warning signals are possible as a warning signal, ie all signals which cause an optical change visible on the vehicle and / or acoustic signals, ie all forms of noise or the change of noises audible by other road users.
- a vehicle impact warning device serves to ensure that a crashed vehicle emits a warning signal that is acoustically or optically noticeable and that it additionally emits a radio signal.
- the first group of warning signals makes it possible for all persons who are within sight or earshot of the accident vehicle to be able to notice the onset of an accident and, secondly, to immediately locate the accident location and thus recognize it quickly and reliably from a greater distance. which has suffered from several vehicles an accident.
- the vehicle impact warning device is suitable for all types of vehicles, such as e.g. for cars, trucks, buses, motorhomes, tractors, construction vehicles, agricultural vehicles, military vehicles and also for safety-sensitive motorcycles in principle. Since the risk of personal injury in motorcycles is in principle higher than in vehicles with closed bodies, the recovery of assistance by the vehicle impact striker is a particularly important advantage of the invention. Also an application for fast watercraft, e.g. Motor boats on busy waterways makes sense.
- An advantage is that the information is passed on immediately after the impact. Another advantage is that the accident becomes identifiable even for those who could not see, hear or hear, but could not see, the accident itself.
- This function can also be valuable for other drivers who are directly behind the accident vehicle since an impact with the front of a vehicle is possible, which is not easily recognizable and / or noticeable on the rear side.
- the crashed vehicle "signals" itself by activating a radio signal, which in the simplest case is a single electromagnetic wave which is continuously radiated.
- a radio signal which in the simplest case is a single electromagnetic wave which is continuously radiated.
- the transmission component required for this is available at low prices according to the current state of the art and, accordingly, also in one embodiment as a safety device with increased requirements for operating temperature range, corrosion resistance and shock sensitivity available at cost, which are hardly worth mentioning compared to the total price of a motor vehicle.
- Radio receiver and the means of identification of the accident Offer at least initialization, but in a further stage of development also offer the implementation of assistance and rescue.
- a prototype equipped with a loudspeaker, a volume control, a warning button, a pilot lamp, a key-operated switch and a loudspeaker is housed in a casing of about 115 mm in length, 35 mm in height and 60 mm in width and weighs just 250 grams.
- GPS signals Global Positioning System
- Standard low-cost chips receive signals from three geostationary satellites, from which they calculate the coordinates of the position and pass them on to the radio transmitter, which emits them immediately together with the radio alarm signal. This information not only informs the responsible control center that an accident has occurred, but also where it occurred.
- the number of occupied seats is recorded before and after the accident, can not after the accident More or apparently additionally occupied seats are concluded that the position of the vehicle occupants has changed as a result of the accident and / or additional objects have fallen onto the seats, which makes a first assessment of the severity of the accident possible.
- the detection of the delay value is conceivable, since proportional to the peak value of the delay, further damage to the vehicle and its occupants are to be lamented.
- the evaluation of the sensors of the Electronic Stabilization Program (ESP) of the vehicle is conceivable in order thereby to transmit the position of the vehicle after the accident, that is to report a possible rollover or overturning of the vehicle to the control center.
- ESP Electronic Stabilization Program
- the vehicle impact warning activates a mobile telephone present in the vehicle and dials a number provided for this emergency.
- the GPS it is possible to record the location of the accident vehicle and, if equipped accordingly, also the Establishment of a speech connection between the responsible accident center and the vehicle occupants.
- the transmission unit of a mobile telephone can be installed in the vehicle impact warning device. Their function can be limited to the fact that they send in an emergency after dialing a special emergency number only a standardized accident report.
- This accident report is used to detect the accident and indirectly to determine the accident location by localizing the mobile transmitting unit of at least two receiving stations. This saves the installation of an additional GPS system.
- the radio transmitter can be differentiated from other signals in radio communication in a particularly safe and trouble-free manner if only a very specific frequency is made available for this purpose.
- the invention prefers the frequency of 433.92 MHz or 868 MHz.
- An alternative is a security lock with a removable key.
- the object of the invention includes the direct warning of other vehicles, in particular especially the hinterherfahrenden.
- the invention proposes that the vehicle impact warning is extended by a radio receiver, which is provided for receiving a radio warning signal from the radio transmitter of another, accident vehicle.
- a radio receiver which is provided for receiving a radio warning signal from the radio transmitter of another, accident vehicle.
- the invention proposes that the signal from the radio transmitter can preferably be emitted only at the rear of the vehicle at a certain angle.
- an additional switch can be provided on the device.
- a speed-dependent activation is conceivable.
- the additional radio receiver should receive priority from the front seen in the direction of travel of the vehicle incoming signals.
- a warning signal as a visual warning signal and / or acoustic warning signal must be triggered.
- a warning light on the dashboard and / or a display in the field of vision of the driver is lit.
- the control lamp provided for this purpose is also activated in the driver's field of vision, as a result of which the visual warning signal in the device of the vehicle impact warning device can be omitted.
- the vehicle impact warning device according to the invention can also trigger acoustic warning signals. This includes the vehicle horn and / or the muting of all audio system loudspeakers in the vehicle.
- these speakers may be used to output a sound signal, unless the vehicle crash warning device has its own loudspeaker and / or its own other sound generating device.
- a sound signal tones are conceivable that sound either evenly or in the volume changeable or variable in pitch.
- a single tone is enough.
- multi-tone signals are possible.
- a possible alternative is, for example, the reproduction of the reserved for emergency sounds of sirens' horns, so the regular change of two tones whose frequency is at a distance of a fourth to each other as defined in DIN 14610, or the sound of a siren.
- a blue light may flash in the driver's field of vision.
- the invention proposes that when receiving a first radio warning signal by a vehicle crash warning in a second reaction stage, a second radio alert emit is.
- the invention recommends that the second radio warning signal can be recognized by additional information for all radio receivers as a second signal. Since in practice the signals are primarily radiated backwards and preferably picked up from the front side, the information is passed on by the identification as a second signal that the accident was indeed close to the receiver, but that in the cases in which the first radio signal has not been received, but only a second, the distance to the accident must be at least as large as the average range of the transmitter, but not greater than twice the range of the radio transmitter.
- the radio transmitter when receiving a second radio warning signal, can emit a third warning signal, so that the information chain is extended counter to the direction of travel to vehicles approaching the scene of the accident.
- the length of this chain should be limited to a meaningful measure, ie no further accident signal should be passed on after receiving a certain number of cascading accident reports to subsequent vehicles. It is conceivable that an estimated value for the distance to the accident site is calculated from the number of cascaded radio alarm signals and the medium range and displayed to the driver.
- the radio receiver may additionally receive radio information signals which should be used above all for information which is relevant for the road users located behind an injured motor vehicle. Examples are instructions like “Making Alley! “or” Drive to the right edge! “ or “accident ahead.” It is also conceivable to pass on search queries such as “doctor wanted” or “volunteer wanted”.
- the invention proposes mounting on the rear parcel shelf below the rear window or on the dashboard. Advantages of these positions are that radio signals can be transmitted and received unhindered through the glass panes of the vehicle.
- the device could also be mounted on the boot lid or on the vehicle roof.
- a vehicle impact warning device as a separate unit results in a higher redundancy of the vehicle warning system and thus also an increased probability of the availability of a warning in the event of severe and extremely serious accidents.
- the standalone configuration used as a standardized part by different vehicles from different manufacturers, offers the opportunity for very large volume production with increased insensitivity to extreme operating temperatures down to - 20 ° and up to + 70 °, against extreme delays above the threshold of 3 - 5 g out as well as against environmental influences, in particular humidity up to constant condensation and the immersion in water in an accident.
- Vehicle crash woofer equipped with a small accumulator be regularly recharged from the electrical system during normal operation of the vehicle and in an emergency in a failure of the on-board voltage network still guaranteed minimum functionalities of the vehicle impact warning.
- These include - in this priority - sending a radio warning signal, closing a relay or other normally open contact and outputting a warning signal. With the relay such warning devices are activated after the accident, which still have access to a ready power supply.
- the invention proposes that the device itself has acoustic warning device, such as a speaker and / or in particular elements with a very good efficiency such.
- Lighting elements such. B. LED 's (light emitting diodes).
- the invention prefers the construction of a device which is as autonomous as possible in the sense of maximum availability.
- a vehicle impact warning device can be expanded by the function of an accident data memory. Particularly interesting is the storage of kinematic and acoustic data of the accident vehicle from the triggering of the deceleration sensor and in a further stage even from a certain period of time directly before the accident event. This combination is ideal because the vehicle impact detector is particularly robust and robust
- Assembly is that is preferably grown in a relatively safe installation location.
- the invention proposes that the radio warning signals, the visual warning signals and the acoustic warning signals are emitted only for a limited, adjustable time, for example 5 to 10 minutes.
- the advantage of this limitation is that the frequency range reserved for emergencies is charged as little as possible and that the disturbance of other, uninvolved road users and residents, in particular by the acoustic warning signal to the necessary minimum is limited.
- the invention proposes that the vehicle impact warning device can emit at least three different acoustic warning signals. It makes sense that the
- warning signal also includes a voice signal.
- voice signal This opens up numerous possibilities for more differentiated information about the reported event. Since modern vehicles are already equipped with warning tones very numerous, is a linguistic message, eg. B. by the word attention a meaningful distinction. Such a short language reserve can be transferred with little effort into the English word attention the French word attention or the Italian word attentione.
- Another device that greatly enhances the practical use value are warning buttons, by the actuation of which an additional voice signal is ever emitted for "obstacle on the road” and / or “broken-down vehicle” and / or “animals on the road” and / or “wrong-way driver” and / or another specific hazard situation.
- An alternative for communicating this information in the receiving vehicle is, in addition to the voice message, the lighting of a text or a pictogram, which is also known as
- Operation switch can be designed for the own transmission of this information.
- the vehicle impact detector is equipped to transmit and / or receive radio frequencies which are intended for use by regionally-competent or even exclusively reserved, the additional use as a receiver for information and / or instructions of these institutions offers itself. It is conceivable that z. B. the Anlagenaufprallwar- ner of authorized transmitters and Authorized Insitutions receives control commands, which are then displayed as a pictogram and / or in a display and / or can be emitted as a voice signal.
- the control signal for activating a warning sound in the interior of the vehicle can be sent over such a frequency that resembles the sound of the Martinhorn, so a Ton mergestrom as z. B. is described in DIN 14610.
- a blue light on the dashboard or in the field of vision of the driver can flash, which not only increases the attention value, but also the legal requirement z. B. for Germany is satisfied that the emergency vehicle only enjoys unlimited right of way, when the blue flashing light and siren are activated simultaneously.
- a particularly valuable additional equipment is a vehicle impact warning device according to the invention in the same form also for motorcycles. Since many motorcyclists succumbed to their injuries after an accident only because they were so far removed from the road by the accident that their vehicle was no longer visible from the road so that they could not be granted much needed help in time , an inventive vehicle crash warning device for a motorcycle is not only a meaningful full information for following road users, but also a very valuable help message with the urgent request for immediate help.
- the invention proposes, as a variant, that the vehicle crash woofer be installed in a housing which has two mutually parallel elongate webs on one outer side and at least one metal clasp over these webs a rail is tensionable, the (the) across the
- the housing can be mounted on a tube of the frame of the motorcycle and clamped on the other side with the metal closure on the frame tube. This makes retrofitting possible with the mechanical strength offered for the impact sensor.
- the metal closure can be designed as a quick-release closure, so that the use of a vehicle impact warning system is possible alternately in several vehicles.
- the motorcyclist also uses his vehicle crash woke in his car.
- the invention proposes as reasonable value for a minimum speed a range of about 55 km / h before.
- FIG. 1 shows a schematic representation of the schematic diagram of a rear-end collision and the transmission of warning signals.
- FIG 1 a total of three motor vehicles 1 are shown in the side view as a vehicle outline. Of these three motor vehicles 1, a second motor vehicle 2 is driven onto the first motor vehicle 1, recognizable by the deformations in the rear of the first motor vehicle and the folds in the front part of the second motor vehicle 1.
- a vehicle impact warning is shown schematically in each case in the area of the parcel shelf. It consists in the lower part of the switch 3 with the triggering deceleration sensor 2. Also in the assembly of the vehicle impact warning the radio transmitter 4 is integrated, which emits a first radio warning signal 41, especially in the rear opposite to the direction of travel of the vehicles on impact. As a result, it encounters the following motor vehicle 1 and reaches the radio receiver 6, which activates the switch 3 and thus then triggers a second radio warning signal 42, which is received by other vehicles in the vicinity.
- third motor vehicle 1 each of the switch 3 is active, in each case a visual warning signal 51 is triggered, in the example shown the hazard warning lights of the vehicle. It is also conceivable activation of the brake lights, tail lights, driving lights or side lighting.
- each activated an acoustic warning signal 52, the z. B. is broadcast by the horn.
- FIG. 1 shows how the crashed vehicle emits a first radio warning signal 41, which is received in the following motor vehicle 1 and triggers a second radio warning signal 41 there, which in turn is emitted to the rear.
- warning signal either as a visual warning signal 51 and / or as an acoustic warning signal 52
- Switch 3 52 Acoustic warning signal triggered by deceleration sensor 2 via switch 3
- radio receiver for receiving the radio warning signals 41 and / or 42
