A vehicle includes a vehicle body arranged along a longitudinal body axis in a body plane and having a first vehicle body end configured to face oncoming ambient airflow when the vehicle is in motion relative to a road surface. The vehicle also includes an active hybrid spoiler assembly mounted to the vehicle body and configured to control a movement of the ambient airflow along the longitudinal body axis. The spoiler assembly includes at least one stanchion mounted to the vehicle body, and first and second wing-shaped side-sections moveably connected to the stanchion(s). The spoiler assembly further includes a mechanism configured to selectively and individually shift each of the first wing-shaped side-section and the second wing-shaped side-section relative to the at least one stanchion to thereby adjust a magnitude of the aerodynamic downforce generated by each of the first wing-shaped side-section and the second wing-shaped side-section on the vehicle body.

A sensor arrangement comprising an angle sensor for measuring torsion is disclosed. The angle sensor is designed for carrying out a measurement via n poles, where n1, and primarily comprises a sensor ring which at least partially surrounds a rotational axis, and a material measure which is rotatable relative to this sensor ring. One transmitting coil and multiple receiver coils are situated on the sensor ring. A magnetic circuit is formed between the transmitting coil and the receiver coils, which magnetic circuit comprises the material measure and a pot core including two limbs. In this case, the material measure forms a variable reluctance in the magnetic circuit. At least one of the two limbs of the pot core is segmented in such a way that the limb comprises ring segments. Each of the receiver coils surrounds at least one of the ring segments. Each of the ring segments forms a circular arc having a mean radius. The ring segments may be provided in pairs. The mean radii of the two ring segments of the individual pairs have an angle () relative to each other of (60/n+i.Math.360/n), wherein i is a whole number. The disclosure further relates to a rolling bearing arrangement.

Described is a system for detecting moving objects. During operation, the system obtains ego-motion velocity data of a moving platform and generates a predicted image of a scene proximate the moving platform by projecting three-dimensional (3D) data into an image plane based on pixel values of the scene. A contrast image is generated based on a difference between the predicted image and an actual image taken at a next step in time. Next, an actionable prediction map is then generated based on the contrast mage. Finally, one or more moving objects may be detected based on the actionable prediction map.

An attitude estimation apparatus for estimating the attitude of a movable body includes an attitude estimation unit for estimating the roll angle of the movable body and for using a calculation process to estimate the offset error for at least one of first and second angular velocity detection units and first, second and third acceleration detection units. The attitude estimation unit includes a plurality of Kalman filters that each receive at least two or more imaginary offset quantities for a detection unit of interest, the imaginary offset quantities being different from each other. Each of the Kalman filters uses detected values from the detection units, estimated values from the previous estimation operation and the imaginary offset quantities to calculate a likelihood, which indicates how reliable the estimated values are. The attitude estimation unit weights the estimated values from the Kalman filters based on the likelihood to estimate the roll angle of the movable body.
