An output pressure module that sets an output pressure of a first component of an exhaust system of the vehicle equal to one of: an input pressure of a second component that is immediately downstream of the first component in the exhaust system; and ambient air pressure. A pressure drop module determines a pressure drop between an input of the first component and an output of the first component based a temperature of exhaust input to the first component. An input pressure module determines an input pressure of the first component based on a sum of the output pressure of the first component and the pressure drop between the input and the output of the first component. An actuator control module selectively controls at least one engine actuator based on at least one of the input and output pressures of the first component.

Exhaust system component input pressure estimation systems and methods

An engine control system includes a fuel system including a first fuel pump in fluid communication with a fuel tank and a second fuel pump in fluid communication with the first fuel pump. A pump control module selectively turns on the first fuel pump when a door opens before an engine is started, the engine is not cranking and a rail pressure of the first fuel pump is less than a predetermined rail pressure.

A distributed battery control network ( ) for a battery string ( ) has a plurality of sensing modules (SM) each associated with one of the batteries in the battery string ( ). Each of the sensing modules has a respective sequencing input (SI) and a sequencing output ( ). Said plurality modules have a sequencing input with a predetermined signature type, storing said address in a particular one of said plurality modules with said sequencing input equal to said signature type, and generating an identifying signature at an output of said particular one of plurality modules with said sequencing input equal to said signature type. A network ( ) is coupled to each of the sending modules. A controller ( ) is coupled to the bus and communicates with each of the sensing modules. The controller ( ) loads each of the sensing modules with an address and a signature type.
