Abstract
A control system for an exhaust system that receives a combusted air/fuel mixture as exhaust from the internal combustion engine includes a catalyst, an electric heating element and a controller. The electric heating element is disposed in the exhaust system upstream of the catalyst and is configured to heat up the exhaust before it enters the catalyst. The controller is configured to: estimate a temperature of the electric heating element at startup of the internal combustion engine; determine a time limit of operating the electric heating element at maximum power based on the estimated temperature of the electric heating element and an ambient temperature; and command the electric heating element to operate at the maximum power based on a determination that the time limit has not been reached.
