Abstract: A method for determining the standardized sooting tendency of a substance mixture and representative indices for calculating an overall sooting tendency. The sooting tendency is determined using gas-chromatographic component analysis of hydrocarbon types and oxygenates of a substance mixture, in particular of a fuel or of an additive via a reformulyzer analysis. A standardized total yield sooting index) of substance mixtures according to YSITotal=?YSIi·Vi/100 is determined, wherein the volumetric proportion (Vi) of each reformulyzer subgroup (i) is multiplied by that of the yield sooting index (YSIi) associated with the reformulyzer subgroup (i), according to which the determined values are summated to the total yield sooting index (YSITotal). Furthermore, method variants are described for determining yield sooting indices (YSIi-M, YSIi-Mid, YSIi-GewM) representing the yield sooting index (YSIi) associated with the subgroups (i).

Abstract: The disclosure relates to a method and a driver assistance system for assisted reversing with a vehicle-trailer combination, wherein it is initially driven forwards, wherein a corresponding forward trajectory is stored and, by means of a sensor system of the towing vehicle, objects arranged laterally next to the forward trajectory are detected. A reversing trajectory, which deviates as little as possible from the driven forward trajectory, and, for each vehicle of the trailer, a vehicle-specific reversing corridor corresponding to the planned reversing trajectory are planned. The detected object in each case is classified as a collision object if it lies in at least one of the planned reversing corridors. In such a case, a new reversing trajectory and, for each vehicle, a new reversing corridor that is free of collision objects is generated. The trailer is then reversed along the new reversing trajectory with the aid of the driver assistance system.

Abstract: The disclosure relates to a method and a driver assistance system for assisted reversing with a vehicle-trailer combination, wherein, initially when it is driven forwards, its forward trajectory is stored and objects arranged laterally next to the forward trajectory are detected. A reversing trajectory, which deviates as little as possible from the driven forward trajectory, is planned. The detected object is classified as a collision object if it lies in the planned reversing trajectory. In such case, a new reversing trajectory that is free of collision objects is generated. The trailer is reversed along the new reversing trajectory. A current deviation of an actual reversing trajectory of the trailer from the new reversing trajectory is thereby determined, and when the current deviation is greater than a permissible limit deviation, the trailer is stopped to allow performing a corrective action. The assisted reversing is resumed after corrective action has been performed.
