EXHAUST SYSTEM PRESSURE ESTIMATION SYSTEMS AND METHODS |
| 摘要 |
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. |

1. A control system for an engine of a vehicle, comprising:
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 that determines the estimated pressure at the location within the exhaust system based on the pressure sum and a reference pressure; and an actuator control module that selectively adjusts at least one engine actuator based on the estimated pressure. |
