Abstract: Systems and methods provide an alternative high voltage cutoff technique for disconnecting a high voltage battery from an electrical network of a vehicle in the event of a fault condition. Embodiments include a vehicle system comprising an electrical bus and a battery module coupled to the electrical bus via a contactor and a disconnector. The vehicle system further includes a controller configured to switch the contactor to an open state, upon receiving a fault condition signal, and if the contactor failed to open, activating the disconnector to break electrical connection between the battery module and the electrical bus. In some embodiments, the fault condition signal is generated upon detecting a vehicular impact. In some embodiments, the disconnector is a pyrotechnic device powered by a vehicle battery included in the vehicle system.

Abstract: A high-voltage system for a vehicle includes a module having a resonant circuit coupled across powerlines, and a controller. The controller is programmed to, during a power up of the high-voltage system, propagate on the powerlines a first signal at a fundamental frequency for a first period. The controller is further programmed to, in response to a first impedance measured across the powerlines at the fundamental frequency during the period being less than a predetermined value, close main contactors to energize the module.

Abstract: An electric drive system for a vehicle includes a speed/position feedback device coupled to an electric machine and configured to provide an index pulse. The system further includes an inverter having a line voltage sensor. The system includes a controller programmed to, responsive to the electric machine rotating at a generally constant speed without commanding the inverter, generate a resolver offset from a time difference between a zero crossing of a line voltage and the index pulse and operate the inverter according to the resolver offset.

Abstract: A vehicle control system includes a controller that is programmed to, in response to an accelerator lift-pedal event, generate a drag torque, with at least one of an engine and electric machine, having a magnitude that is based on a deceleration fuel shut-off torque of the engine and a desired power output of the electric machine, and limit the drag torque to a threshold value that is based on the deceleration fuel shut-off torque.

Abstract: A vehicle is disclosed having a motor and engine selectively coupled to the motor via a clutch. The vehicle includes a controller configured to, in response to a vehicle wheel torque reversal, open the clutch to disconnect the engine from the motor, command the engine to enter a speed control mode, and control a motor output torque through a region surrounding the vehicle wheel torque reversal to reduce torque disturbances in a vehicle driveline.

Abstract: A auto-stop/start vehicle with an engine and a battery includes at least one controller that calibrates an engine auto-stop delay time based on a state of charge (SOC) of a battery. The calibrated engine auto-stop delay time increases as the SOC of the battery decreases, and decreases as the SOC of the battery increases. The controller further initiates shutdown of an engine upon expiration of the calibrated engine auto-stop delay time.

Abstract: A vehicle, a control system for a vehicle having a user interface, and a method of controlling a vehicle are provided. In response to input selecting an electric-only operating mode, an engine is disabled such that the vehicle is propelled by an electric machine. In response to detecting a predefined vehicle state while the electric-only operating mode is selected, the engine is re-enabled such that the vehicle is propelled by at least one of the engine and electric machine. In response to detecting an absence of the predefined vehicle state while the electric-only operating mode is selected, the engine is disabled such that the vehicle is propelled by the electric machine.
