Crank velocity driveline filtering for consecutive misfire detection
26 Jan 21
A misfire detection system and method for a vehicle utilize a controller to obtain a crankshaft speed signal indicative of a rotational speed of an engine crankshaft connected to a device that mitigates vibrational disturbances at the crankshaft caused by misfires of the engine, detect that a first firing event of the engine is a first misfire based on the crankshaft speed signal, monitor a vibrational response of the crankshaft, detect that a consecutive second firing event of the engine is a second misfire based on a first modified crankshaft speed signal and the first set of thresholds, and in response to detecting the second misfire, reset the monitoring of the vibrational response of the crankshaft including modifying the amplitude of the crankshaft speed signal to obtain a second modified crankshaft speed signal and comparing the second modified crankshaft speed signal to a set of thresholds.

Gear position estimation techniques for a manual transmission of a vehicle include estimating a gear ratio of the manual transmission based on measured speeds of the vehicle and its torque generating system and when the estimated gear ratio is not within a threshold amount from any known gear ratios of the manual transmission, detecting at least two gear shifts of the manual transmission and determining a set of possible axle/tire ratios each indicative of a ratio of an axle ratio of the vehicle to a tire circumference of the vehicle after each gear shift, wherein each set includes values based on the measured torque generating system and vehicle speeds and each of the known gear ratios of the manual transmission, selecting and utilizing one of the possible axle/tire ratios that is common across all of the sets of possible axle/tire ratios.

A diagnostic system and method for a crankcase ventilation system of an engine having a boost system utilize a pressure sensor configured to measure a pressure in a make-up air (MUA) hose, a flow-limiting valve (i) fixedly attached to the induction system at a point upstream from the pressure sensor and proximate to an induction system end of the MUA hose and (ii) configured to limit flow through the MUA hose, and a controller configured to, in response to detecting the non-boost operating condition of the engine, obtain an initial pressure from the pressure sensor and then command the flow-limiting valve to close for a diagnostic period, during which monitor the pressure is monitored to determine a pressure drop from the initial pressure, and when the pressure drop fails to exceed a threshold during the diagnostic period, detect a malfunction indicative of a leaking or disconnected MUA hose.
