Embodiment Construction

[0062] According to the invention, by determining the tolerance band, the so-called predicted quality, a tolerance band is also calculated in addition to the predicted driving curve. The prediction quality provides a report for the entire route: whether the driver stays in a tolerance band based on a stochastic analysis process and of course existing. The operating strategy for the vehicle precisely takes this tolerance band into account during optimization.

[0063] As long as the driver remains within the predicted tolerance band of the driving curve during real driving, no recalculations or changes to the operating strategy are required. Fuel consumption is thus minimized on a predetermined route by means of a predictive operating strategy.

[0064] As described, for example, in the unpublished DE 10 2010 047 080.5, the speed profile of each route can be described by a defined movement class (referred to as "course" in DE 10 2010 047 080.5). Examples for such action categ...

Abstract

The invention relates to a method and a device for determining a prediction quality with respect to a predicted energy consumption of a motor vehicle. By determining the prediction quality, a tolerance band is also calculated in addition to the predicted driving curve. The predictive quality provides a report on the entire road segment: whether the driver is staying in a tolerance band that is based on a stochastic analysis process and of course exists. If the driver remains within the predicted tolerance band of the driving curve during actual driving, no recalculation or change of the operating strategy is necessary. Fuel consumption is minimized on a predetermined route by means of a predictive operating strategy.

Description

technical field [0001] The invention relates to a method and a device for determining a prediction quality with respect to a predicted energy consumption of a motor vehicle. Background technique [0002] In the engine control or operating strategies of motor vehicles, in particular electrified or hybrid vehicles, the current sensor data are now largely used to control the powertrain without taking into account the entire planned route profile of the drive. This is disadvantageous in that an optimal adaptation of the engine control or operating strategy to the planned route profile is thus not possible. [0003] Different methods have been developed to overcome this disadvantage. Thus, for example, DE 10 2008 035 944 A1 discloses a method for optimizing the driving situation of a motor vehicle on the basis of a plurality of parameters, in which the vehicle's driving route is determined by specifying the driving destination, and a plurality of different The geometric positio...
