  • Publication number: 20170144627
    Abstract: A system for a vehicle includes a gear and a plate fixed to the gear. The gear is driving by a motor for providing relative rotation between a steering wheel and steering shaft of the vehicle in an adaptive front steering system. The system includes a solenoid including a coil and a pin moveable relative to the coil to engage the plate based on a signal. A sensor is configured to detect a change in current through the coil associated with initial movement of the pin relative to the coil. The system includes a controller programmed to change the duty cycle signal in response to the change in current to slow movement of the pin to reduce or eliminate a clicking noise associated with the pin seating in an extended position or retracted position.

  • Patent number: 9656556
    Abstract: A drive system for an electric vehicle includes an input capacitor selectably coupled to a DC power source (e.g., battery) by a contactor. A variable voltage converter couples the input capacitor to a main link capacitor, and an inverter couples the main capacitor to a machine load (e.g., motor and/or generator). During a normal or emergency shutdown, the contactor is opened. In order to quickly discharge the input capacitor when the contactor opens, A) the converter operates in a boost mode to transfer charge from the input capacitor to the main capacitor until the input capacitor discharges to less than a threshold voltage, B) the converter deactivates to prevent transferring charge from the main capacitor to the input capacitor, and C) the main capacitor can then be discharged through the inverter.

  • Patent number: 9656657
    Abstract: A parallel hybrid vehicle includes an engine and a motor separated along a driveshaft by a clutch. The motor can operate (either alone or in combination with the engine) to provide positive drive torque to the wheels. The motor can also act as a generator and provide negative torque when converting mechanical energy from the driveshaft into mechanical energy to be stored in a battery. The clutch selectively couples the motor to the engine. Torque and its effects on the clutch can vary dramatically when the motor changes from providing positive and negative torque, and vice versa, while the engine is running. At least one controller in the vehicle is programmed to, while the engine is running, initiate an increase in pressure at the clutch in response to an anticipated change in torque provided by the motor from positive to negative or from negative to positive.

  • Patent number: 9657660
    Abstract: Methods and systems are provided for improving surge detection and mitigation. In one example, a surge detection method may selectively filter an aggregate of temperature-adjusted manifold pressure and boost pressure in a frequency range indicative of surge to reduce the effect of non-minimum phase behavior of throttle inlet pressure on surge detection. In addition, the noise contribution of particular engine actuators on throttle inlet pressure in the selected frequency range may be accounted for, reducing the occurrence of false surge indications.

  • Patent number: 9657663
    Abstract: Methods and systems are provided for detecting an air-fuel imbalance based on output from multiple degradation monitors. In one example, a method comprises, during feedback engine air-fuel ratio control responsive to output of an exhaust gas sensor positioned downstream of a catalyst, indicating a cylinder imbalance responsive to a catalyst transfer function determined only within a specified frequency range based on the exhaust gas sensor output after determining that the catalyst is nominal, and adjusting an actuator in response to the indicated cylinder imbalance. In this way, air-fuel ratio imbalances may be accurately identified and mitigated, thereby reducing emissions.

  • Patent number: 9657671
    Abstract: Methods and systems are provided for reducing late burn induced cylinder pre-ignition events. Forced entry of residuals from a late burning cylinder into a neighboring cylinder may be detected based on engine block vibrations sensed in a window during an open exhaust valve of the late burning cylinder. In response to the entry of residuals, a pre-ignition mitigating action, such as fuel enrichment or deactivation, is performed in the neighboring cylinder.

  • Patent number: 9657672
    Abstract: A method of monitoring an exhaust gas sensor coupled in an engine exhaust in an engine is provided. The method includes adjusting engine operation responsive to exhaust gas sensor degradation, the degradation identified during deceleration fuel shut-off (DFSO) and compensated based on whether vapor purge operation is occurring in the engine during DFSO.
