Definitions

• the invention relates to a method for detecting danger points in a guidance and information system for road vehicles in individual traffic, in which a navigation device is arranged in the vehicle with a terminal for entering location coordinates and for display for route guidance and with an information transmission device, and in which Fixed beacons are arranged in the area of the carriageway, which transmit guidance and location information to passing vehicles and receive messages from the vehicles and transmit them to a control center.
• Such guidance and information systems are known.
• a guidance system for individual traffic is described in DE-OS 29 36 062, in which the guidance information is transmitted from a host computer to the passing vehicles via beacons.
• the vehicle For the processing of the guidance information, for the input of the target information and for the acquisition of the vehicle data, such as the route covered by amount and direction, vehicle speed, vehicle identification, the vehicle has an on-board device which essentially has a device for acquiring the vehicle data and a navigation device with a terminal for input and display, as is already known from DE-OS 29 41 331 and DE-OS 29 36 062.
• DE-OS 29 45 852 describes a method for traffic detection in a guidance and information system for the Indian vidual traffic known, in which data is also transmitted from the vehicle to the beacons and from there to a host computer.
• the object of the invention is in a known control and information system for road vehicles in individual traffic to detect dangerous hazards, as explained above, in order to warn vehicles approaching the danger spots at an early stage and, in the event of an accident, to provide rapid and targeted assistance.
• This object is achieved in such a control and information system according to the invention in that a message about an accident or a danger point is transmitted to the control center and, if appropriate, to a rescue control center with at least one report button for accidents or dangers additionally arranged on the terminal Type of danger is marked that the position and the identification of the vehicle is automatically transferred to the control center at the same time and that such danger messages are transmitted from the control center via beacons to vehicles approaching the danger point and displayed on the vehicle terminal.
• a hazard message is initiated with a message button, which is arranged in the vehicle at the terminal of the navigation device for the guidance and information system.
• the type of danger is identified.
• the exact position of the danger point is also determined, which is determined when the danger message button is pressed using the navigation device on board the vehicle was automatically transferred.
• the identifier of the vehicle is also passed on, the identifier being not only the identifier of the vehicle in question but also the type of vehicle, such as a car, bus, tanker truck with a dangerous load, etc.
• the message is transmitted, for example, when passing the next beacon from the vehicle to the beacon, and from there generally to the line-bound to the control center.
• the danger messages recorded and possibly evaluated by the master computer are transmitted via the control and information system as a warning to a danger point to those vehicles which are moving towards the danger point and thereby pass beacons from which the information is transmitted to the vehicles, for example with infrared light.
• This method of detecting the danger point has the advantage on the one hand that dangers can be reported and help can be obtained and on the other hand that other road users can be reliably informed or warned of such danger points at an early stage.
• the vehicle expediently has a simple radio transmitter that is assigned to the navigation device.
• the accident report is therefore sent via radio, whereby the position and the characteristic data of the vehicle are also automatically transmitted.
• the control center can initiate appropriate measures based on the type of notification.
• This accident emergency notification procedure has the decisive advantage that the exact position of the vehicle is automatically sent as well.
• Peilempftulern to subsequently, after discontinuation of an N otrufs troublesome to locate the vehicle is unnecessary. So there are simple radio receiver sufficient that the received N otrufmeldung to the central monitoring station and forward possibly to a rescue control center.
• a separate, appropriately labeled message button can advantageously be provided for the respective message type. If there are not too many types of message provided, this is a simple and expedient arrangement for triggering an accident or hazard message by pressing the corresponding key.
• the danger message can be triggered or initiated and the type of danger can be identified with just one message button.
• the type of the various hazard messages is displayed one after the other by pressing the report button on the terminal. If there is a corresponding danger displayed on the terminal, the report button is pressed again so that the danger displayed there is reported and transmitted to the control center.
• the "accident" hazard message is automatically transmitted from the vehicle that is directly involved in the accident to the control center or from there to the rescue control center.
• the driving speed of the vehicle which is recorded anyway by the navigation device, is used. If the vehicle speed is jerkily braked from a predetermined minimum speed to the value zero, ie the vehicle suddenly comes to a stop, the "traffic accident” hazard message is transmitted via the radio transmitter.
• This method has the advantage that an accident can also be reported when the driver is no longer himself is able to do so because, for example, he has suffered a shock or is so injured that he can no longer operate the report button.
• a delay from the automatic triggering of the accident report to the stopping, ie sending, of the accident report is expediently provided in order to avoid an error report which can occur, for example, when the vehicle is braked suddenly with full braking, ie with blocking wheels. If the blocked wheels move again within a predetermined time, for example several seconds, the initiated accident report is interrupted and not sent.
• the engine in the event of an abrupt braking of the vehicle until the wheels lock or until the vehicle comes to a standstill, the engine can also come to a standstill, as is the case in the event of an accident, as an undelink to trigger a automatic accident reporting can be used.
• this method also expediently also provides a time delay of several seconds until the message is sent. If the engine is started again within this delay time, the accident message will not be given. sends.
• the hazard warning system can be switched on automatically when a hazard message is triggered if the vehicle is at the hazard message or is moving slowly (e.g. at walking speed), as is the case, for example, when driving slowly onto a traffic jam or comes to a stand there.
• the hazard warning lights can be switched on when driving slowly by triggering the message.
• the hazard warning system can be switched off again when the vehicle accelerates, ie when the vehicle continues to drive or becomes faster.
• the method according to the invention can provide that the hazard report is initiated when the report button is actuated and is only issued with a time delay.
• the triggering of a hazard message is indicated optically and / or acoustically until the time the hazard message is transmitted or sent.
• the triggered danger message can be reset within this time.
• the driver can prevent a message by pressing a button within this time.
• a hazard message in combination with the hazard warning system can be linked to one another in such a way that the hazard warning is initiated when the hazard warning system is switched on and that the hazard message is issued with the report button on the terminal.
• the message can be prepared when the hazard warning lights are switched on, i.e. the various types of hazard messages are displayed in sequence on the terminal, and the hazard message is issued by pressing the message button for the type of hazard message displayed.
• the initiated emergency call message can be reset by switching off the hazard warning lights.
• the license plate number of the vehicle be it the motor vehicle License plate or a kind of travel call identification for the vehicle is also transmitted. This is done automatically, since an identifier is arranged in the navigation device, which also encodes the type of vehicle. If the type of vehicle is also identified, it can be seen whether an accident report is, for example, a bus, a tanker truck or a truck with a dangerous load. The police in the rescue control center can initiate the appropriate relief measures. In the case of an accident, the identifier "bus" shows that many people can be involved and that a corresponding number of emergency vehicles have to be dispatched. Labeling a dangerous cargo enables the appropriate measures to be taken immediately.
• Such accident reports are expediently carried out with the emergency transmitter of the accident vehicle. If an accident report from an unaffected vehicle passing the accident site when passing the next beacon by transmitting the accident report from the vehicle to the lead beacon, it is not necessary in this case to include the type of the reporting vehicle, i.e. the identification of the vehicle type transferred to.
• a manually triggered danger message can only be given when the ignition is switched on. This is to prevent abuse, e.g. prevent children playing in the parked vehicle from reporting a danger or an emergency.
