摘要： A vehicle includes an electric machine operated by an inverter. The electric machine includes a gate driver configured to energize a switch of the inverter with a pulse width modulation (PWM) signal. The gate driver is configured to delay the PWM signal by a dependent amount that is a function of a magnitude of current of a lead of the electric machine. The delay is responsive to a polarity of the current being positive.

摘要： A trim component is provided. The trim component may include a trim panel, a backing layer, and at least one light pipe. The trim panel may have tapered side walls that extend from an inner portion of the panel and terminate at an edge to define a moonroof opening. The backing layer may wrap around the edge to define a trim ring. The trim panel may include integrated carriers that may project away from the panel and around the trim ring. The at least one light pipe may be disposed within the integrated carriers.

摘要： An electric motor/generator includes a stator-core enclosing a rotor-core, which are each formed from stacked annular laminates. The stator-core laminates are configured to reduce vibration, and each have teeth extending radially inward from a root of an annular stator yoke/back-iron, to a flux-cap. Each tooth is formed to have opposite, lateral-edges spaced a distance-apart that changes between the root to the flux-cap, to establish a variable tooth-stiffness and a predetermined mechanical-resonance of the tooth. The opposite lateral-edges may each be configured with either a linear or a non-linear, curved edge-profile, and to have the variable tooth-stiffness and the lateral-edge distance-apart changing or decreasing between the root and the flux-cap. Each tooth may also have an edge-profile that is different from at least one adjacent tooth, and which is configured with a variable tooth-stiffness and a predetermined mechanical resonance that is different from the at least one adjacent tooth.

摘要： A switch assembly includes a switch unit including a button and an arm extending from the button along a height direction, the arm including first and second contact portions spaced apart from each other along a longitudinal direction; and a slider unit extending along a width direction and including a nose to contact the first and second contact portions respectively at first and second engagement positions. The switch assembly provides a reduced need for space and enhanced friendliness in touch and feel.

摘要： An electric drive system for a vehicle includes an electric machine having first conductors arranged in slots of a stator to form phase windings and a second conductor arranged in the slots to form a secondary winding that produces a voltage indicative of a common mode voltage caused by voltages applied to the phase windings. The voltage can be used to supply power to electronic components and for diagnosis and control of the electric machine and an associated inverter.

摘要： A vehicle powertrain includes a DC-DC converter and a controller. The DC-DC converter is coupled between a traction battery and an inverter for an electric machine. The controller is configured to, in response to a rotational speed of the electric machine dropping below a back EMF threshold speed, transition to a current control based six step inverter mode and operate the DC-DC converter to output a voltage less than an open circuit voltage of the traction battery.

摘要： An electric machine is configured with at least two sets of phase windings. A plurality of power switches is configured to selectively couple voltage terminals to each of the phase windings. A controller is programmed to operate the power switches according to a switching pattern, for each of the sets, updated at intervals defined by a switching frequency such that the switching patterns are different during each one of the intervals.

摘要： A DC-DC converter for a vehicle includes a controller programmed to, in response to changes in an output voltage of the converter, adjust a control signal that controls an output voltage of the DC-DC converter to drive a ratio of a first error between a reference current and a current through the inductor to a second error between a voltage reference and the output voltage to a predetermined value.
