Abstract: A control system for an engine of a vehicle includes an adder module that determines a pressure sum based on a sum of a plurality of pressures determined based on (i) a plurality of operating parameters of the vehicle and (ii) a plurality of predetermined values calibrated for determining an estimated pressure at a location within an exhaust system of the vehicle. An estimating module determines the estimated pressure at the location within the exhaust system based on the pressure sum and a reference pressure. An actuator control module selectively adjusts at least one engine actuator based on the estimated pressure.

Abstract: A fuel vapor control system for a vehicle includes a fuel vapor canister that traps fuel vapor from a fuel tank of the vehicle. A purge valve opens to allow fuel vapor flow to an intake system of an engine and closes to prevent fuel vapor flow to the intake system of the engine. An electrical pump pumps fuel vapor from the fuel vapor canister to the purge valve. A pressure sensor measures a pressure within a conduit at a location between the electrical pump and the purge valve. A purge control module, based on the pressure measured using the pressure sensor at the location between the electrical pump and the purge valve, controls at least one of a speed of the electrical pump and opening of the purge valve.

Abstract: A fuel vapor system for a vehicle includes a fuel vapor canister that traps fuel vapor from a fuel tank of the vehicle. A purge valve opens to allow fuel vapor flow to an intake system of an engine and closes to prevent fuel vapor flow to the intake system of the engine. An electrical pump pumps fuel vapor from the fuel vapor canister to the purge valve. A diagnostic module (a) selectively diagnoses a fault in the fuel vapor system based on at least one of: (i) a speed of the electrical pump measured using a pump speed sensor; and (ii) a pressure at a location between the electrical pump and the purge valve, and (b) illuminates a malfunction indicator lamp (MIL) within a passenger cabin of the vehicle when the fault is diagnosed.

Abstract: A control system of a vehicle includes a fuel vapor canister that traps fuel vapor from a fuel tank of the vehicle. A purge valve, when open, allows fuel vapor flow into an intake system of an engine at a first location and, when closed, prevents fuel vapor flow to the intake system of the engine. A purge control module controls opening of the purge valve and determines a fuel vapor flow into cylinders of the engine based on: (i) a first pressure at the first location, (ii) a second pressure at a second location between the purge valve and the intake system, and (iii) at least one delay period between opening of the purge valve and fuel vapor reaching cylinders of the engine.

Abstract: A fuel vapor control system for a vehicle includes a fuel vapor canister that traps fuel vapor from a fuel tank of the vehicle. A purge valve opens to allow fuel vapor flow to an intake system of an engine and closes to prevent fuel vapor flow to the intake system of the engine. An electrical pump pumps fuel vapor from the fuel vapor canister to the purge valve. A vent valve allows fresh air flow to the vapor canister when the vent valve is open and prevents fresh air flow to the vapor canister when the vent valve is closed. A purge control module controls a speed of the electrical pump, opening of the purge valve, and opening of the vent valve.

Abstract: A control system for an engine of a vehicle includes an adder module that determines a temperature sum based on a sum of a plurality of temperatures determined based on (i) a plurality of operating parameters of the vehicle and (ii) a plurality of predetermined values calibrated for determining an estimated temperature at a location within an exhaust system of the vehicle. A temperature difference module determines a temperature difference based on the temperature sum and a previous value of the temperature difference. An estimating module determines the estimated temperature at the location within the exhaust system based on the temperature difference and a reference temperature. An actuator control module selectively adjusts at least one engine actuator based on the estimated temperature.
