Abstract
An exhaust brake control system includes a braking torque estimation module that estimates a desired braking torque based on engine speed. A volume flow rate determination module determines a desired volume flow rate of an exhaust gas based on the desired braking torque. An adjustment module adjusts an actual volume flow rate to control actual braking torque based on the desired braking torque and a change in exhaust temperature.
