Abstract
Modification of reductant (e.g., diesel exhaust fluid, DEF) tank location, for example during vehicle up-fitting may result in less than optimal operation of the DEF system due to inaccurate DEF system calibration. In one example approach, the above issue can be at least partially addressed by adjusting control system parameters for system control and diagnostics based on an input indicative of, or any modification to, the DEF tank location. In this way, DEF tank location flexibility is maintained, while also maintaining emission control and diagnostic accuracy.
Claims16
A method of configuring a controller of a vehicle with an exhaust system including a reductant storage vessel, comprising:
- receiving vehicle exhaust system configuration information;
- adjusting exhaust system operating parameters based on the received exhaust system configuration information.
A vehicle, comprising:
- a reductant storage tank;
- a selective catalytic reduction catalyst;
- a reductant delivery line coupled between the reductant storage tank and upstream of the selective catalytic reduction catalyst;
- a computer readable storage medium having instructions encoded thereon, including:
- instructions to receive external information;
- instructions to adjust control system parameters based on the received external information;
- and
- instructions to deliver the reductant to the selective catalytic reduction catalyst based on the adjusted control system parameters.
