Abstract: An automotive vehicle includes a body with an upper surface defined by a front fascia disposed proximate a fore end, and a closure panel with a fore edge proximate the front fascia. A deflector with a first end and a second end is movably coupled to the upper surface and is movable between a stowed position and a deployed position. In the stowed position the second end projects a first distance from the upper surface and in the deployed position the second end projects a second distance from the upper surface. The second distance is greater than the first distance. A controller is configured to, in response to satisfaction of a first operating condition, control an actuator to move the deflector from the stowed position to the deployed position.

Abstract: A vehicle includes a vehicle body having a first end configured to face oncoming airflow when the vehicle is in motion relative to a road surface and an opposing second end and an under-hood compartment provided in the first end of the vehicle body. An underbody extends between the first and second ends of the vehicle body and defines a space between the vehicle body and the road surface. At least one aerodynamic member is disposed adjacent a forward portion of the underbody and proximate to the under-hood compartment. The at least one aerodynamic member includes a housing and an airflow management device provided in an opening in the housing. The airflow management device is selectively positioned to direct the airflow from the front end of the vehicle into the under-hood compartment to improve vehicle performance.

Abstract: A Lidar system, a mirror assembly for a Lidar system and method of operating the mirror assembly. The mirror assembly of the Lidar system includes a first frame and a first conductor. The first frame is rotatable about a first axis. The first conductor extends along the first frame to one side of the first axis. The first conductor extends through a first magnetic field on the one side of the first axis in a direction parallel to the first axis. A first current is passed through the first conductor to interact with the first magnetic field to induce a first rotation of the first frame about the first axis.

Abstract: A vehicle having an active panel is disclosed. The vehicle defines a rearmost surface. The vehicle includes a frame defining a D-pillar, an active panel, and an actuation system. The active panel extends in a fore-and-aft direction of the vehicle and covers at least a portion of the D-pillar. The active panel defines a trailing edge that is oriented towards an aft direction and is moveable between a stowed position and a deployed position. The actuation system is operatively connected to the active panel and is configured to extend the active panel from the stowed position into the deployed position and from the deployed position into the stowed position. The trailing edge of the active panel is substantially aligned with the rearmost surface of the vehicle in the stowed position and extends beyond the rearmost surface of the vehicle in the deployed position.

Abstract: A method of mitigating rear end contamination of a vehicle while driving using an active spoiler system includes providing an active rear spoiler to a square back vehicle. Next, determinations are if the vehicle speed is greater than a predetermined threshold, if the rear end of the vehicle is contaminated, and if the vehicle wipers are on. The method then moves to deploying the active rear spoiler when the vehicle speed is greater than a predetermined threshold, the rear end is contaminated, and the vehicle wipers are on.

Abstract: An automotive vehicle includes a body having a fore portion, an aft portion, and an underbody portion. The vehicle additionally includes a panel pivotably coupled to the underbody portion proximate the aft portion of the body. The panel has a fore edge and an aft edge and is pivotable about the fore edge. The panel is pivotable between a stowed position and a deployed position. In the stowed position the aft edge is spaced a first distance from a driving surface and in the deployed position the aft edge is spaced a second distance from the driving surface. The second distanced is less than the first distance. The vehicle additionally includes an actuator configured to move the panel between the stowed position and the deployed position in response to satisfaction of an operating condition.

Abstract: A floor pan includes a mid-body portion having a bottom wall. The bottom wall includes a forward end and a rearward end spaced from each other along a longitudinal axis. The mid-body portion of the floor pan is spaced above a reference plane, e.g., a ground surface, a first height at the forward end of the bottom wall, and is spaced above the reference plane a second height at the rearward end of the bottom wall. The second height is less than the first height to position the second end of the bottom wall nearer the reference plane than the first end of the bottom wall. The contoured shape of the mid-body portion provides an aerodynamic shield to direct airflow underneath components of the vehicle located rearward of the rearward end of the mid-body portion of the floor pan, as well as additional under-floor storage space.
