[0031] Various measures for exhaust gas aftertreatment in the exhaust system of the internal combustion engine, such as the regeneration of the particle filter, can be delayed by means of the navigation data and started at an optimal point in time. In this way, inter alia, long-term fuel savings can be achieved. Preferably, the navigation system organizes the planned driving route into individual, successive segments 20.1, 20.2, 20.3, 20.4, 20.5, 20.6, 20.7, 20.8, 20.9, 20.10, 20.11, ...

Abstract

The invention relates to a method for planning measures for exhaust gas aftertreatment or on-board diagnostics of an internal combustion engine on the basis of expected route data, wherein the driving route is divided into segments and wherein a segment-evaluation is determined for each segment Number and segment‑duration. Here it is provided that one or more consecutive segments are grouped in a window such that measures for exhaust gas aftertreatment or for carrying out on-board diagnostics can be completely carried out in this window; several windows are arranged along the driving route ; A window-evaluation number is determined for each window from the segment-evaluation number and the segment-duration of the segments included therein; and the measures for exhaust gas aftertreatment or for carrying out on-board diagnostics are as follows in said window: the window is selected taking into account said urgency and said window-evaluation number. The method enables measures for exhaust gas aftertreatment or execution of on-board diagnostics with low fuel consumption.

Description

technical field [0001] The invention relates to the planning of measures for exhaust gas aftertreatment or for the execution of an internal combustion engine of a motor vehicle on the basis of expected route data along a planned driving route, in particular based on route data ascertained by means of a navigation system. Method of measures for on-board diagnostics, wherein the driving route is divided into segments, wherein for each segment a segment-evaluation number and a segment-duration are ascertained, the segment-evaluation number reflecting the The suitability of the measures for the exhaust gas aftertreatment or the suitability of the section of the on-board diagnosis, and wherein the urgency for carrying out the measures for the exhaust gas aftertreatment or for carrying out the on-board diagnosis is determined. [0002] The invention also relates to a control device for carrying out the method. Background technique [0003] Various measures for exhaust gas aftertr...
