Abstract:
Methods and systems are provided for removing moisture from an engine exhaust system. In one example, a method includes, during a vehicle key-off condition, in response to a higher than threshold exhaust moisture level and a lower than threshold engine run time during an immediately prior drive cycle, operating an electric air compressor to remove the moisture accumulated in the exhaust manifold.

Claim (Index 18):
A system, comprising:\n a vehicle, including an autonomous vehicle and/or a hybrid vehicle; an electric machine coupled to a battery for propelling the vehicle; an engine including one or more cylinders, an intake manifold, and an exhaust manifold; an intake passage including a compressor, a charge air cooler (CAC) downstream of the compressor, and an intake throttle downstream of the CAC; a conduit coupled to the intake passage downstream of the compressor and upstream of the CAC, the conduit including a motor-driven electric compressor; an electric compressor bypass valve coupled at a junction of the intake passage and the conduit; one or more sensors including each of an ambient humidity sensor coupled to the intake manifold and an exhaust temperature sensor coupled to the exhaust manifold; one or more cameras to capture images of a windshield; an exhaust gas recirculation (EGR) passage coupling the exhaust manifold to the intake manifold, downstream of the compressor, the EGR passage including an EGR valve; and a controller with computer readable instructions stored on non-transitory memory to: estimate moisture level in the exhaust manifold at the end of a drive cycle based on one or more images of the windshield, ambient humidity as estimated via the ambient humidity sensor, a duration of engine operation, and a variation in exhaust temperature during the drive cycle; and in response to a higher than threshold moisture level, during an immediate subsequent vehicle key-off condition, operate the electric compressor to route compressed air through the exhaust manifold to remove moisture from the exhaust manifold.
