Abstract: A multi-cylinder group engine system operable in at least a first mode and a second mode, where in the first mode a first and second cylinder group combust air and fuel with a lean air-fuel ratio, and where in the second mode at least one of the first and second cylinder groups combusts air and fuel and the other one of the first and second cylinder groups pumps air without injected fuel, the engine system comprising of a fuel injection activity sensor coupled to each cylinder in the first and second cylinder groups; a exhaust gas sensor disposed in an exhaust passage to measure air fuel exhausted from the engine; and a controller configured to transition out of the first mode responsive to detection of exhaust gas sensor degradation and to transition out of the second mode responsive to detection of fuel injection sensor degradation. In one example, the transition out of the second mode may be slower than the transition out of the first mode in response to the respective degradation.

Abstract: A vehicle powertrain including a multiple cylinder internal combustion engine and a controllable transmission controls engine shutdown by shutting off a fuel supply device or devices such as a fuel pump or fuel injector(s) while the transmission is in gear to load the engine and reduce or eliminate engine run-on. The transmission may be controlled to couple the input shaft to a stationary component or simultaneously engage clutches corresponding to different gear ratios to provide a holding torque on the engine.
Abstract: A tire pressure monitoring system (12) for an automotive vehicle (10) has a receiver circuit (28). The vehicle (12) has a plurality of wheels (14A-14D). A plurality of antennas (31A-31D) are adjacent to one of the wheels (14A-14D). The plurality of antennas receive RF signals from a pressure sensor (16A). An adder circuit (30) is coupled to the receiver circuit and the plurality of antennas. The adder circuit receives the RF signals and adds them together to form a sum signal. The sum signal is coupled to the receiver circuit.
Abstract: An interior armrest for an automotive vehicle includes upper and lower horizontal walls and a channel-shaped lateral impact contactor joined to the upper horizontal walls by the means of shear planes. The lateral impact contactor has a number of wedge-shaped vertical interruptions which cooperate with the shear planes to produce a controlled collapse in the event of a lateral impact of an occupant of the vehicle against the armrest.

Abstract: A tire pressure monitoring system (12) for a vehicle (10) includes a vehicle speed sensor (38, 98) that is used to generate a vehicle speed signal. A receiver (28) operates using a first protocol when the vehicle speed signal is below a first speed threshold and operates using a second protocol when the vehicle speed is above the speed threshold. A remote keyless entry system (23) is coupled to the receiver and operates when the vehicle speed is below a speed threshold. The remote keyless entry system (23) receives signals from a keyless entry transmitter (60) using the first protocol. A tire pressure monitoring system (12) has a pressure transmitter (16A-16E) that generates a signal using a first protocol and a second protocol when the speed signal is below the speed threshold and generating the signal using only the second protocol when the speed signal is above the speed threshold.

Abstract: A method for controlling engagement and release of friction clutches in a multiple-ratio transmission for a hybrid electric vehicle powertrain uses electric motor torque to augment engine torque as a power-on downshift is commanded. Near the end of a downshift event, total powertrain torque is modulated or reduced to reduce torque disturbances.

Abstract: A method controlling a hybrid electric vehicle. The hybrid electric vehicle includes a power transfer unit having a plurality of gear ratios and at least one power source adapted to drive the power transfer unit. The method includes calculating a speed ratio value, comparing the speed ratio value to a threshold value, and inferring a torque disturbance if the speed ratio value is greater than the threshold value.
Abstract: A carrier assembly for a planetary gearset of a transmission includes a pinion carrier, a one-way brake having a rocker ring integral with the carrier and having multiple pockets mutually spaced about an axis and located on an outer radial surface of the carrier. A cam ring includes multiple notches angularly spaced about the axis and facing the rocker ring. A rocker, located in each pocket, pivots about a pivot center to engage the cam ring, and a spring urges each rocker to pivot toward engagement with the cam ring. A hydraulically actuated friction brake secured to the carrier alternately holds the carrier against rotation relative to a housing and permits the carrier to rotate.
Abstract: A system for detecting an alignment of a sensor mounted on a vehicle and a method of making the same is disclosed. The system includes a vehicle windshield having the sensor mounted thereto at a predetermined location. At least one conductive strip is included having a first and a second end, wherein the conductive strip is attached to the windshield. The system further includes at least one conductive point disposed between the windshield and the sensor and mounted at the first and the second end. The conductive point establishes a closed circuit between the conductive strip and the sensor so long as the sensor is mounted to the windshield at the predetermined location. Upon displacement of the sensor from the predetermined location, an open circuit occurs between the conductive strip and the conductive point. Accordingly, the sensor generates signals indicating the misalignment of the sensor.
Abstract: A system (18) for controlling a safety system (44) of an automotive vehicle (10) includes a longitudinal acceleration sensor (36), a vehicle speed sensor (20), a lateral acceleration sensor (32), a yaw rate sensor, and a controller (26). The controller (26) determines a reference pitch in response to the longitudinal acceleration signal and the vehicle speed signal and a reference roll angle in response to the yaw rate signal, the wheel speed signal and the lateral acceleration signal. The controller (26) determines a roll stability index and a pitch stability index. The controller (26) determines an adjusted pitch angle in response to the reference pitch angle and the pitch stability index and an adjusted roll angle in response to the reference roll angle and the roll stability index. The controller (26) controls the safety system (44) in response to the adjusted roll angle and the adjusted pitch angle.

Abstract: A powered lift gate for an automotive vehicle includes a lift gate door hinged to a vehicle body. A motor system which opens and closes the door is operated by a controller coupled to a primary obstacle detection system which senses operation of the motor itself, and by a secondary detection system which directly senses an object interposed between a margin of the door and the door opening panel. A pinch protection member interposed between a marginal zone of the door and the door opening panel includes a resilient element having sufficient strength to support an object positioned between the door and the door opening panel such that the primary obstacle detection system will be triggered when the door and motor develop a predetermined compressive force upon the object. The predetermined compressive force is selected to allow normal operation of the lift gate, without subjecting an obstructing object to excessive crushing force.
