Abstract
A method for controlling exhaust flow in an EATS of a vehicle. A NOsensor output parameter is monitored. It is determined that the NOsensor output parameter is below a limit. When the NOsensor output parameter is below the limit, it is determined that a first part of the exhaust flow should bypass at least a first area of the SCR unit and that a second part of the exhaust flow should be inputted to at least the first area of the SCR unit. It is initiated that the first part is bypassed and that the second part is inputted to at least the first area of the SCR unit. An amount of reductant that should be added to the second part of the exhaust flow is determined. Addition of the amount of reductant is initiated.
