Abstract

A method for controlling exhaust gas emission of a motor vehicle may include determining when the motor vehicle drives into a low-emission zone, wherein the low-emission zone dictates a maximum emission level for the motor vehicle; reducing actual accelerator actuation signals of the motor vehicle to effective accelerator actuation signals within the low-emission zone; and trimming an actual intake temperature of the motor vehicle, being measured with an intake temperature sensor of the motor vehicle, to an effective intake temperature when the actual intake temperature falls outside a predetermined temperature range within the low-emission zone; wherein at least one of the effective accelerator signals and the effective intake temperature are used as inputs for controlling an exhaust gasrecirculation (EGR) subsystem of the motor vehicle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102019204810.2 filed April 4, 2019, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a control system and method for controlling exhaust emissions of a motor vehicle during operation of an internal combustion engine, in particular a diesel engine. Background technique [0004] Many cities and towns around the world have implemented or prepared so-called low-emission zones, defined areas where certain motor vehicles are restricted or prohibited from entering, with the aim of improving air quality. In particular, vehicles with internal combustion engines operating on diesel fuel are adapted gradually to local conditions. These vehicles need to ensure that the emission level under actual driving conditions is below a certain set level, for example the emission of n...
