Abstract: A vehicular lane keeping assist system includes a camera and a control having an image processor that processes image data captured by the camera to determine lane boundaries defining a traffic lane of a road traveled by the vehicle. The control adjusts control of steering of the vehicle responsive to determination that the vehicle is traveling along a curved section of the road traveled by the vehicle. The control controls steering of the vehicle at a first degree responsive to determination that the vehicle is at or near a determined first lane boundary of the traffic lane at an inboard region of the curved section of the road, and the control controls steering of the vehicle at a second degree responsive to a determination that the vehicle is at or near a determined second lane boundary of the traffic lane at an outboard region of the curved section of the road.

Abstract: An autonomous vehicle driving system includes a control that autonomously controls the vehicle. The control, upon receipt of a destination geographical location, controls the vehicle to travel to the destination geographical location, and wirelessly receives data pertaining to driving conditions relevant to the route being traveled by the vehicle. Responsive to the received driving conditions data, the control determines a geographic location ahead of the vehicle along the route where driving of the vehicle by an occupant of the vehicle is desired. When the vehicle is traveling along the route and toward the determined geographic location and is within a threshold time and/or distance to the determined geographic location, the control informs the occupant of distance to and/or time of travel to the determined geographic location so the occupant is prepared to take over control of the vehicle and drive the vehicle upon the vehicle reaching the determined geographic location.

Abstract: A lane keeping assist system of a vehicle includes a camera and control having an image processor that processes image data captured by the camera to determine a lane boundary of a lane of a road traveled by the vehicle. The control establishes a virtual boundary line at an initial location relative to the determined lane boundary, with the initial location of the virtual boundary line at or inboard of the determined lane boundary. The control, responsive to a lateral speed of the vehicle relative to the determined lane boundary, laterally adjusts the virtual boundary line relative to the determined lane boundary. Responsive to a determination that the vehicle, when moving towards the determined lane boundary, would cross the virtual boundary line, the control at least one of (i) generates an alert to the driver of the vehicle and (ii) controls a steering system of the vehicle.

Abstract: A vehicle power distribution system for selectively providing battery power to a circuit. A circuit-interrupting device is arranged to respond to a control signal by selectively applying the battery power to the circuit. A circuit protection device is moveable between a first circuit position and a second circuit position, where the first circuit position is arranged to pass a current through the circuit concurrently with the circuit interrupting device. The second circuit position is arranged to pass the current around said circuit interrupting device.

Abstract: A method is provided for applying spark corrections calculated on an individual cylinder basis to the total spark advance for the motor vehicle engine to counter torque imbalances and stabilize crankshaft or engine accelerations. According to the invention, crankshaft feedback is used to measure an average acceleration of the crankshaft attributable to each cylinder. Thereafter, individual cylinder spark corrections designed to equalize the accelerations of each of the cylinders are calculated based on the individual cylinder average accelerations. The calculated individual cylinder spark corrections are then applied to the total spark advance. Preferably, an event delay is employed to correct for the phase lag caused by filtering the crankshaft accelerations which aligns the spark corrections with the proper cylinder.

Abstract: A methodology of computing a learned combustion stability value and applying the learned combustion stability value to control engine operation is provided. Engine speed is sensed for each expected firing of individual cylinders ofthe engine. An expected acceleration value is determined using a band-pass-filtered engine speed difference. The difference between successive expected acceleration values is computed. A learned combustion related value is determined as a function of the difference in the successive learned acceleration values and is an indication of engine combustion quality. The operation of the engine is controlled as a function of the learned combustion related value. The learned combustion stability value is advantageously employed so as to modify the fuel injection to an internal combustion engine, especially following a cold engine start so as to reduce hydrocarbon emissions.

Abstract: A method of misfire detection for an internal combustion engine in a motor vehicle includes the step of sampling a misfire indicator and filtering the misfire indicator to provide a filtered misfire indicator. The method also includes the step of selecting one misfire indicator point from the filtered misfire indicator. The method further includes the steps of comparing the one misfire indicator point to a misfire threshold to detect a misfire event and identifying a misfire if a misfire event is detected.

Abstract: A methodology of computing a learned combustion stability value and applying the learned combustion stability value to control engine operation is provided. Engine speed is sensed for each expected firing of individual cylinders of the engine. The difference in engine speed for a selected cylinder firing and a cylinder firing occurring two cylinder firings earlier is determined to provide an expected acceleration value. The difference between successive expected acceleration values is computed. A learned combustion related value is determined as a function of the difference in the successive learned acceleration values and is an indication of engine roughness. The operation of the engine is controlled as a function of the learned combustion related value. The learned combustion stability value is advantageously employed so as to modify the fuel injection to an internal combustion engine, especially following a cold engine start so as to reduce hydrocarbon emissions.

Abstract: The present invention provides a system for detecting and removing resonance from crankshaft speed measurements comprising signal demodulation and deconvolution processing. According to the invention, a crankshaft speed sensor sends an appropriate signal corresponding to crankshaft speed to an engine controller. The input signal with resonance noise is subjected to a demodulation operation in N demodulation subsystems for resonance detection and identification. Also, the input signal with resonance noise is subjected to a deconvolution operation in N deconvolution subsystems for resonance noise removal. The demodulated signals are compared to a given set of criteria for selecting a desired signal subsystem. The desired demodulated signal subsystem is then used to screen the deconvolved signal so that only a matching deconvolved signal exits the system as the system output.
