Exhaust Brake Torque Systems

Abstract

An exhaust brake torque system for a vehicle including an engine includes a controller configured to determine a current exhaust brake torque and a maximum exhaust brake torque. A display is configured to display at least one of the current exhaust brake torque, the maximum exhaust brake torque and a percentage corresponding to the current exhaust brake torque divided by the maximum exhaust brake torque. An engine speed sensor determines an engine speed of an engine. A pressure sensor is configured to sense turbine inlet pressure. The controller is configured to calculate the current exhaust brake torque and the maximum exhaust brake torque in response to the engine speed and the turbine inlet pressure.
