Definitions

  • the present invention relates to a method for improving the passage of emergency vehicles, in which the emergency vehicles circulating through the road network and using said method have means for determining the position, (such as for example a global navigation satellite (GNSS) receiver, such as GPS or Galileo), and a terminal with access to a wireless access network (for example, the mobile telephone network) and which is connected to said means for determining the position.
  • GNSS global navigation satellite
  • the network Knowing the position of the emergency vehicle at each time, the network warns the remaining vehicles in the road network, provided that they are close to the emergency vehicle, of the safety parameters (such as maximum allowed speed, safety distance with the vehicle in front of it) and other actions which they must comply to facilitate the passage of said emergency vehicle, minimizing the risk of accidents.
  • the safety parameters such as maximum allowed speed, safety distance with the vehicle in front of it
  • the alert passage of emergency vehicles is currently based on using acoustic and light signals so that the remaining vehicles with which they share the road clear their path and allow them to reach their destination in as short a time as possible.
  • the vehicles in front of the emergency vehicles do not know if the vehicle is before or after them and on which lane they are approaching, such that on many occasions they cannot carry out any manoeuvre to clear the path of the EVs.
  • the method object of the invention solves the drawback set forth because it informs the drivers to clear the path of the emergency vehicles and thus reduces the time of arrival to their destination, in addition to increasing the safety especially in crossroads.
  • Patent documents on similar methods for improving the passage of emergency vehicles include US2003/141990 .
  • each emergency vehicle announces itself (and its position) as a hazard to other road users to a centralised data delivery centre which in turn broadcasts alert information to drivers of other vehicles.
  • the receiving driver's system determines whether the hazard is relevant to the driver by comparing its own position to the broadcast position of the hazard, alerting the driver if it is relevant.
  • the present invention relates to a method for improving the passage of emergency vehicles according to claim 1 and claim 10, in its two alternative solutions. Preferred embodiments of said method are defined in the dependent claims.
  • each emergency vehicle subscribing to a service of traffic accident prevention for emergency services has:
  • the method described in claim 1 comprises, for each emergency vehicle subscribed to the TAPES service, the following steps:
  • the network informs said remaining vehicles of the presence of the emergency vehicle through their own terminals TE, sending them safety parameters (maximum allowed speed, for example) which they must comply and optionally a message requiring a specific action from them, such as clearing one of the lanes for example.
  • the emergency vehicles subscribe to the TAPES service is they want the remaining vehicles to be warned of their presence.
  • the vehicles participating in the TAPES service are those that are connected to the wireless access network by means of a terminal in each vehicle, and can receive information from the TAPES service to warn them of the presence of an emergency vehicle.
  • the vehicles that do not have a terminal to access the wireless access network do not participate in the TAPES service, and therefore cannot receive messages from the wireless access network.
  • the vehicles that do not participate in the TAPES service could be warned, for example, by means of informative panels controlled by the TAPES service itself and located in problematic points of the road network (in the reference points RPs). Traffic lights and other types of signs could also be controlled if the TAPES service had permission, to thus warn all the vehicles located close to the emergency vehicle.
  • the wireless access network can periodically send a new identifier IDEV TEMP to the emergency vehicle.
  • the method can be implemented such that the emergency vehicle sends the wireless access network its position, its temporary identifier JDEV TEMP and optionally its circulating direction when such network requires it.
  • the subscription of the emergency vehicle to the TAPES service can end either when said emergency vehicle does not contact the network in a predetermined time period TEXP or when said emergency vehicle sends the network a request for ending the subscription to the TAPES service.
  • the terminal TE of the emergency vehicle must send the following data to the network to carry out a new subscription: the position of the emergency vehicle, the identifier of the TAPES service which is being requested, the temporary identifier IDEV TEMP of said terminal TE and optionally the circulating direction.
  • the wireless access network then checks that the validity period of said IDEV TEMP has not expired.
  • the terminal TE sends a request to the wireless access network
  • the network checks the user identity and the validation of the subscription of the terminal TE in the same manner as in the first described method.
  • the wireless access network only sends one temporary identifier IDEV TEMP of the terminal TE, and does not send information about the RPs.
  • the network like in the first described method, informs the remaining vehicles which are located at a predetermined distance from the emergency vehicle in the presence thereof.
  • the terminal TE of the emergency vehicle periodically sends the wireless access network the identifier IDEV TEMP , the position of the emergency vehicle and optionally the circulating direction of the emergency vehicle.
  • the emergency vehicle can send the wireless access network its position, its temporary identifier IDEV TEMP and optionally its circulating direction when such network requests it.
  • the wireless access network can in turn periodically send a new identifier IDEV TEMP to the emergency vehicle.
  • the manner in which the wireless access network informs the remaining vehicles of the presence of the emergency vehicle is identical to the one already described.
  • the process for ending the subscription to the service and new subscription is also the same as that already described for the first method.
  • the method object of the invention is based on the availability, in the emergency vehicle 1, of means for determining the position for example, and in the case of Figure 1 , a global navigation satellite GNSS receiver 2 (GPS, Galileo, etc.) providing position measurements of the vehicle in which it is installed, said GNSS receiver 2 having connected thereto a terminal TE 3 of the driver of said vehicle 1, which terminal 3 has installed therein a client application and has access to the information supplied by the GNSS receiver 2, such that the location of the vehicle 1 is locally determined (in the vehicle 1 of the user).
  • GPS global navigation satellite GNSS receiver 2
  • the method has the following steps:
  • the network 4 can periodically send a new IDEV TEMP to the emergency vehicle.
  • the network 4 can also request the emergency vehicle 1 to send it its current position, temporary identifier and circulating direction.
  • the terminal TE 3 of the emergency vehicle 1 remains inactive for a time period to be defined (i.e., if it does not communicate with the wireless access network 4 during a certain time period), said terminal TE 3 must subscribe again.
  • the emergency vehicle 1 itself can also voluntarily end its subscription when it does not need to move in emergency.
  • the emergency vehicle 1 wants to subscribe again, it will do so by sending the same parameters as those indicated in S1 if a validity time period, set by the network 4 according to configuration, associated to said emergency vehicle 1, has passed. Steps S2, S3, S4 would be carried out without modification. If said time period had expired, the network would send the following parameters in subscription step S1:
  • step S2 the network would check that said IDEV TEMP has not expired and therefore, the access to the service is assured. And there would be no modification in steps S3 and S4.
  • the solution described in the method object of the invention is valid for any vehicle which is not an emergency vehicle 1 without requiring anything other than such vehicle having the application loaded in the terminal TE and a GNSS receiver.
  • the ID EV could be its license number and the IDEV PASS could be the reason for which the service is needed.
  • the activation and therefore, the insertion in the database of the network in which the allowed pairs (ID EV , IDEV PASS ) are registered) could be carried out from an emergency call center.
