Abstract
Methods and systems are provided for adjusting engine operating parameters in response to an emission output from vehicles within a region. In one example, a method comprises adjusting engine operating parameters in a portion of the vehicles to decrease an emission output therefrom.
Claims20
A system, comprising:
- an engine fluidly coupled to an exhaust passage housing an aftertreatment device;
- and
- a controller with computer-readable instructions stored thereon that when executed enable the controller to:
- estimate a total current emission output of all vehicles within a region;
- adjust engine operating parameters of a portion of all vehicles within the region if the total current emission output is greater than an emission target of the region.
2 more elements
A method, comprising:
- estimating a total emission output of all vehicles within a region, wherein the estimating includes calculating an emission output of a plurality of vehicles within the region and using an average emission output of the plurality of vehicles to assume an emission output of a remaining portion of vehicles;
- and
- adjusting engine operating parameters in the plurality of vehicles in response to the total emission output being greater than an emission target of the region.
A system, comprising:
- an engine fluidly coupled to an exhaust passage housing an aftertreatment device;
- and
- a controller with computer-readable instructions stored thereon that when executed enable the controller to:
- estimate a total current emission output of all vehicles within a region;
- adjust engine operating parameters of a portion of all vehicles within the region if the total current emission output is greater than an emission target of the region, wherein the emission target is adjusted based on weather in the region.
