A vehicle door assembly includes a vehicle body having an A pillar, a C pillar, an upper rail, and a rocker rail that together define an access opening. A front door is movably connected to the body near the A pillar, and a rear door is movably connected to the body near the C pillar. The rocker rail defines a front compartment adjacent the A pillar and a rear compartment adjacent the C pillar. A front actuator is positioned in the front compartment and a rear actuator is positioned in the rear compartment. A front linkage connects the front door, the front actuator, and the body near the A pillar, and a rear linkage connects the rear door, the rear actuator, and the body near the C pillar. Actuation of the actuators causes the linkages to move the front and rear doors between open and closed positions.

A method for determining a battery current in an integrated motor drive (IMD) system having a plurality of integrated power modules includes: generating, by a power electronics assembly of an integrated power module, alternating current (AC) power on a set of load terminals using DC power from the one or more battery cells connected to a DC port of the integrated power module; determining a total DC current on the DC port of the integrated power module; measuring a battery voltage of the one or more battery cells of the integrated power module; determining, based on the battery voltage, a capacitor current through a DC link capacitor connected in parallel with the one or more battery cells of the integrated power module; and determining, based on the total DC current and the capacitor current, the battery current in the one or more battery cells of the integrated power module.

A method of operating a power converter (10) for exchanging power with an alternating current (AC) grid (30) includes: commanding one or more switches to selectively conduct a current between a DC storage device (20) and the AC grid (30) via a series combination of a resistor and an inductor; measuring a current through the series combination of the resistor and the inductor; and determining, based on the measured current, an estimated grid voltage of the AC grid (30). The one or more switches are commanded based on the estimated grid voltage. The power converter (10) is operated in each of: a pre-synchronous mode before energy is exchanged between the DC storage device (20) and the AC grid (30), and a post-synchronous mode while energy is exchanged between the DC storage device (20) and the AC grid (30). Different techniques are used to determine the estimated grid voltage in the pre-synchronous mode and in the post-synchronous mode.

A secondary (recycled) aluminum alloy for casting into a structural component, such as a vehicle component, is provided. The aluminum alloy includes at least 80 wt. % aluminum, 0.1 wt. % to 0.6 wt. % copper, 6.0 wt. % to 8.0 wt. % silicon, 0.10 wt. % to 0.60 wt. % magnesium, 0.10 wt. % to 0.50 wt. % zinc, 0.12 wt. % to 0.30 wt. % iron, 0.2 wt. % to 0.6 wt. % manganese, not greater than 0.15 wt. % titanium, 0.015 wt. % to 0.03 wt. % strontium, other elements each in an amount of not greater than 0.05 wt. %, and other elements in a total amount of not greater than 0.15 wt. %, based on the total weight of the aluminum alloy.

A cradle for supporting a drive system of a vehicle includes at least one pair of side structures that extend generally in spaced and parallel relationship with one another. Each of the side structures extends between a front portion and a rear portion. At least one cross structure extends laterally between the rear portions of the side structures. At least one drive system coupler is connected to at least one of the structures for coupling the cradle to the drive system of the vehicle. At least one body coupler is connected to at least one of the structures for coupling the cradle to a body of the vehicle. A gap is defined between the front portions of the side structures such that no cross structure is located between the front portions of the side structures.

A camera module (20, 120, 220) for a vehicle includes: a housing (30, 130, 230) including a front surface (32) defining a plurality of receiver ports (34) and an emitter port (36); a lens (40) mounted on the front surface (32) of the housing (30, 130, 230); a camera imager sensor (50) disposed in the housing (30, 130, 230) and behind the lens (40) for receiving light via the lens (40); a plurality of ultrasonic sensors (44); and an ultrasonic transmitter / driver (46). Each of the ultrasonic sensors (44) is disposed in the housing (30, 130, 230) and overlying a corresponding one of the receiver ports (34). The ultrasonic transmitters (46) disposed in the housing (30, 130, 230) and overlying the emitter port (36) for directing ultrasonic energy therethrough.

A vehicle bumper assembly includes a bumper beam extending from a first beam end to a second beam end to present an outer bumper surface and an inner bumper surface disposed in generally spaced relationship to one another. At least one crash box is disposed adjacent one of the first or second beam ends and extends from a first crash box end secured to the inner bumper surface to a second crash box end to define a crash box cavity. A flange plate is secured to the second crash box end and defines an expansion hole. An energy absorption structure is housed within the crash box cavity and increases in cross-sectional profile from a second absorption end nested within the expansion hole to a first absorption end secured to the outer bumper surface for being pushed through and radially deforming the expansion hole during an impact to absorb additional energy.
