Description

[0001] The invention relates to a method for determining the fuel consumption of a specific combination of a towing vehicle with a trailer or semi-trailer according to the preamble of claim 1.

[0002] Determining the energy consumption of a towing vehicle with a semi-trailer or trailer of unknown type is difficult because individual consumption figures and the interaction (e.g., the cW*A value of the combination) between the truck and the semi-trailer or trailer are not known in advance.

[0003] It is known to calculate the expected range and consumption for a specific distance based on measured variables (e.g. speed, gradient) and fixed parameters (e.g. rolling resistance coefficient, efficiency maps of the drivetrain).

[0004] DE 10 2021 20 0183 A1 describes a method for determining the expected range of a vehicle when towing a trailer, wherein the vehicle has a trailer coupling for coupling with a trailer to form a vehicle combination, comprising: - Determination and / or storage of at least one trailer parameter, in particular an extension quantity and / or a weight for a trailer coupled and / or to be coupled to the vehicle, wherein the extension quantity is characteristic of a geometric extension of the trailer in at least one direction, by a determination device; - Determination of a range value that is characteristic of the expected range of the combination of the vehicle and the trailer, based on at least one trailer parameter by a range determination device of the vehicle.

[0005] The invention is based on the objective of providing a novel method for determining the fuel consumption of a specific combination of a towing vehicle with a trailer or semi-trailer.

[0006] The problem is solved according to the invention by a method for determining the fuel consumption of a specific combination of a towing vehicle with a trailer or semi-trailer having the features of claim 1.

[0007] Advantageous embodiments of the invention are the subject of the dependent claims.

[0008] A method for determining the fuel consumption of a specific combination of a towing vehicle with a trailer or semi-trailer is proposed, wherein fuel consumption data from a fleet of towing vehicles with trailers or semi-trailers are collected from real routes, wherein trailer information relating to the trailer or semi-trailer, including axle configuration, model and vehicle identification number, tire pressure, tire temperature and / or brake application, is collected in the towing vehicle via a towing vehicle-trailer interface, wherein vehicle data of the towing vehicle, including energy consumption, route data, speed data, model and vehicle identification number, is recorded in the towing vehicle.wherein a consumption calculation for a specific combination or for a structurally identical combination with a towing vehicle of the same type and a trailer or semi-trailer of the same type is carried out based on the information obtained for this purpose. According to the invention, it is provided that the consumption data of the fleet of towing vehicles with trailers or semi-trailers from real routes are collected in a backend and / or a cloud, wherein for specific configurations consumption-relevant parameters are resolved according to towing vehicle and trailer or semi-trailer, wherein the trailer information and the vehicle data are transferred to the backend and / or the cloud, and wherein the consumption calculation is carried out on request in the backend and / or in the cloud.

[0009] The present invention enables a more accurate determination of consumption based on fleet data compared to data from a train combination.

[0010] Exemplary embodiments of the invention are explained in more detail below with reference to a drawing.

[0011] This shows: Fig. 1: a schematic representation of a procedure for determining the fuel consumption of a specific combination of a towing vehicle with a trailer or semi-trailer.

[0012] The only Fig. Figure 1 is a schematic representation of a method for determining the consumption of a specific combination K1 to K8 of a towing vehicle TR with a trailer AN or semi-trailer (truck-trailer combination) based on cloud data of a fleet of towing vehicles TR with trailers AN or semi-trailers (truck-trailer fleet).

[0013] In this process, fuel consumption data (VD) of the fleet of tractor units (TR) with trailers (AN) or semi-trailers on real routes is collected in a backend (BE) and / or a cloud. For specific configurations, consumption-relevant parameters are resolved according to tractor unit (TR) and trailer (AN) or semi-trailer. This creates a database with fuel consumption information for tractor units (TR), trailers (AN), or semi-trailers and their combinations (K1 to K8).

[0014] Furthermore, trailer information regarding trailer AN is collected in the towing vehicle TR via a towing vehicle-trailer interface, in particular: - an axle configuration, - a type (model) A, B, C, D of the trailer AN and a vehicle identification number I, 1, 2, 3, 4, 7 (VIN) of the trailer AN, - tire pressure and / or tire temperature, - a brake application.

[0015] Furthermore, vehicle data of the towing vehicle TR is recorded, in particular: - an energy consumption, - Route data, - Speed ​​data, - a type (model) A, B, C, D of the towing vehicle TR and a

[0016] Vehicle identification number I, 1, 2, 3, 4, 7 (VIN) of the towing vehicle TR.

[0017] The trailer information and vehicle data are transferred to the BE backend and / or the cloud.

[0018] In the backend BE and / or in the cloud, precise consumption calculations can be performed for a specific combination K1 to K8 or for a structurally identical combination K1 to K8 (with a tractor unit TR of the same type A, B, C, D and a trailer AN or semi-trailer of the same type A, B, C, D) by providing parameters for this combination K1 to K8. The condition of the trailer AN or semi-trailer (tire pressure, tire temperature, and / or brake application) and the condition of the tractor unit TR (energy consumption, route data, speed data) can also be taken into account.
