Method for storing and evaluating status information recorded within a V2X network
Technologies and techniques for assigning anonymized status information recorded by vehicles in a V2X network to respective vehicles when an irregular event such as an accident occurs. An anonymized assignment takes place by comparing the status information with vehicle information relating to vehicles involved in an irregular event. Therefore, despite the status information being in an anonymized form, when an irregular event occurs, the information is assigned to the individual vehicles and the event, in particular the accident, is thus reconstructed.
1 . A method for storing and evaluating status information recorded within a vehicle-to-x (V2X) network, comprising:
receiving status information of a plurality of vehicles;
recording the received status information in a memory unit in anonymized form, and removing an identifier that associates the status information to the associated vehicle such that the recorded status information cannot be directly assigned to a vehicle;
detecting or receiving vehicle information about vehicles involved in an irregular event; and
assigning a set of status information to one of the vehicles involved in the irregular event by comparing the anonymized recorded status information with the vehicle information to determine that the set of status information corresponds to said one of the vehicles involved in the irregular event.
2 . The method according to claim 1 , wherein assigning the set of status information comprises assigning the set of status information in an infrastructure unit, a roadside unit (RSU) or a server.
3 . The method according to claim 1 , wherein the status information
relates to the operation of vehicles within a predetermined time period prior to the irregular event; and/or
is received from vehicles involved in the irregular event.
4 . The method according to claim 1 , further comprising requesting the status information from one or more vehicles in response to the detection or reception of the vehicle information.
5 . The method according to claim 1 , wherein the status information comprises characteristic data relating to at least one of (i) a vehicle, (ii) an occupant of the vehicle, (iii) cargo of the vehicle.
6 . The method according to claim 5 , wherein the status information relating to the vehicle comprises trip data, including one or more of speed, steering angle, brake activation, turn signal activation, data regarding a selected driving mode and/or environmental settings.
7 . The method according to claim 1 , wherein the vehicle information comprises a point in time and/or location of the irregular event, changes in speed or driving direction of the vehicle, end positions and/or a driving direction of individual vehicles involved in the irregular event.
8 . The method according to claim 1 , wherein the recording the received status information comprises cyclically deleting the received status information, provided no vehicle information is being received or detected.
9 . The method according to claim 1 , wherein assigning the set of status information comprises storing the set of status information in a blockchain.
10 . A computer apparatus, comprising one or more of an infrastructure unit, a roadside unit (RSU) or a server, communicatively coupled to a vehicle-to-x (V2X) network, comprising:
a communication unit, configured to communicate data with the V2X network;
a memory, operatively coupled to the communication unit, the memory being configured to record data; and
a control unit, operatively coupled to the memory, the control unit being configured to:
receive status information of a plurality of vehicles via the communication unit;
record the received status information in the memory in anonymized form, and remove an identifier that associates the status information to the associated vehicle such that the recorded status information cannot be directly assigned to a vehicle;
detect or receive vehicle information about vehicles involved in an irregular event; and
assign a set of status information to one of the vehicles involved in the irregular event by comparing the anonymized recorded status information with the vehicle information to determine that the set of status information corresponds to said one of the vehicles involved in the irregular event.
11 . The computer apparatus of claim 10 , wherein the status information
relates to the operation of vehicles within a predetermined time period prior to the irregular event; and/or
is received from vehicles involved in the irregular event.
12 . The computer apparatus of claim 10 , wherein the control unit is configured to request the status information from one or more vehicles in response to the detection or reception of the vehicle information.
13 . The computer apparatus of claim 10 , wherein the status information comprises characteristic data relating to at least one of (i) a vehicle, (ii) an occupant of the vehicle, (iii) cargo of the vehicle.
14 . The computer apparatus of claim 13 , wherein the status information relating to the vehicle comprises trip data, including one or more of speed, steering angle, brake activation, turn signal activation, data regarding a selected driving mode and/or environmental settings.
15 . The computer apparatus of claim 10 , wherein the vehicle information comprises a point in time and/or location of the irregular event, changes in speed or driving direction of the vehicle, end positions and/or a driving direction of individual vehicles involved in the irregular event.
16 . The computer apparatus of claim 10 , wherein the control unit is configured to cyclically delete the received status information, provided no vehicle information is being received or detected.
17 . A vehicle configured to communicate in a vehicle-to-x (V2X) network, comprising:
a communication unit for data communication within the V2X network;
a sensor unit for detecting status information and vehicle information; and
a control unit, configured to:
activate the sensor unit for detecting status information related to the vehicle and vehicle information;
activate the communication unit for transmitting the detected status information to an infrastructure unit, a roadside unit (RSU) and/or a server of the V2X network utilizing a message;
determine an irregular event for the vehicle; and
transmit, via the communication unit, vehicle information associated with the irregular event to the RSU and/or to the server of the V2X network to enable assignment of a set of status information to one of the vehicles involved in the irregular event by comparing anonymized recorded status information with the vehicle information to determine that the set of status information corresponds to said one of the vehicles involved in the irregular event.
18 . The vehicle according to claim 17 , wherein the status information is transmitted in anonymized form to the RSU or the server.
19 . The vehicle according to claim 17 , wherein the vehicle information relates to another vehicle.
20 . The vehicle according to claim 17 , wherein the status information comprises characteristic data relating to at least one of (i) a vehicle, (ii) an occupant of the vehicle, (iii) cargo of the vehicle.
