Abstract
A method performed by a device for handling data associated with energy consumption of a vehicle in operation. The device obtains modelling data associated with energy consumption of a model vehicle. The modelling data are generated by a digital model of the vehicle in operation. The device obtains operating data associated with energy consumption of the vehicle in operation. The device compares the operating data to the modelling data. Based on a result of the comparing, the device detects a discrepancy between the operating data and the modelling data and associated with the energy consumption. The device evaluates the detected discrepancy associated with the energy consumption. The device triggers an operation when the discrepancy has been detected.
Claims
exact text as granted — not AI-modified1 . A method performed by a device for handling data associated with energy consumption of a vehicle in operation, the method comprising:
obtaining modelling data associated with energy consumption of a model vehicle, wherein the modelling data are generated by a digital model of the vehicle in operation; obtaining operating data associated with energy consumption of the vehicle in operation; comparing the operating data to the modelling data; based on a result of the comparing, detecting a discrepancy between the operating data and the modelling data and associated with the energy consumption; evaluating the detected discrepancy associated with the energy consumption; and triggering an operation when the discrepancy has been detected.
2 . The method according to claim 1 , wherein the evaluating the detected discrepancy associated with the energy consumption comprises one or more of:
evaluating energy consumption of the vehicle in operation; detecting malfunction of the vehicle in operation; determining a reason for the discrepancy; determining a vehicle configuration change; and determining a vehicle operation change.
3 . The method according to claim 1 , wherein the operation comprises one or more of:
providing information associated with the discrepancy; triggering an alert; initiating scheduling of a service operation; and requesting input from a user of the vehicle in operation.
4 . The method according to claim 1 , wherein the modelling data and the operating data are both based on static data and/or dynamic data.
5 . The method according to claim 1 , comprising:
obtaining a statistical distribution of the modelling data; and wherein the comparing the operating data to the modelling data comprises: comparing operating data to the statistical distribution of the modelling data to determine if the operating data is according to the statistical distribution or not.
6 . The method according to claim 1 , wherein the evaluating the detected discrepancy associated with the energy consumption comprises:
determining a user anticipation score for a user of the vehicle in operation, wherein the user anticipation score is:
