摘要： Radome for vehicles comprising a light source (28); a front unit (9) comprising a transparent layer (11) and a colored decoration layer (5); and a reflective light guide unit (10) comprising a light guide (13) and a reflective subunit (14), the front unit (9) and the reflective light guide unit (10) containing a layer (16) with a refractive index lower than the refractive index of the light guide (13) between them, wherein the reflective subunit (14) comprises a reflective layer (22), the reflective subunit (14) forms an integral single part with the light guide (13), positioned on its face opposite to the front unit (9).
The usage of a reflective unit at the rear of the light guide avoids the need of an air gap at the rear surface of the light guide, and the removal of the rear air gap improves the transmission performance of the radome.

摘要： A system for determining an angle α between a longitudinal axis of a vehicle and an authenticator, in particular a key or a keyless entry device for a vehicle, wherein the angle α can be calculated with the system using the formula α=(dr−dl)* kw, where dr is the calculated and/or measured distance to the authenticator from an antenna mounted on the right side in or on the vehicle, dl is the calculated and/or measured distance to the authenticator from an antenna mounted on the left side on the vehicle, and kw is a correction factor for the angle calculation that is established in a vehicle-specific manner.

摘要： The disclosure relates to an antenna-retaining device for a motor vehicle. The antenna-retaining device includes an antenna carrier plate for retaining a monopole antenna in an emitting position; and a motor-vehicle coupling device for fastening the antenna carrier plate to a vehicle body. The antenna carrier plate is electrically conductive and thus forms an electrical counterpoise to the monopole antenna. The antenna-retaining device includes an electrically conductive tab element as a counterpoise extension. The antenna carrier plate and the counterpoise extension are interconnected. When the monopole antenna is retained in the emitting position, the monopole antenna and the counterpoise extension are arranged on opposite sides of the antenna carrier plate, and a surface of the counterpoise extension and a planar emitting region or a longitudinal axis of the monopole antenna include an angle in the range of 90° to 180°.

摘要： A method and apparatus for detecting static objects and broadside objects in a vehicular radar system is presented. Detection data within a field of view for a host vehicle is acquired. A histogram process is used to determine a presence of at least one of a static object and a broadside vehicle. The histogram process includes generating ratios of a relative velocity of an object (Vr) to host velocity (Vh) from acquired detection data and determining a number of detections which occur at an angle α corresponding to an intersection of two lines with a first line represented by Vr/Vh=0 and a region of a second line within the FOV along which Vr/Vh≠0. The detections are filtered to identify only those detection points at a first and second predetermined values of α, wherein the identified detections indicate a presence of a static object and/or a broadside vehicle.

摘要： Vehicles, systems, and methods are provided electronic communication in a vehicle. A vehicle includes a vehicle body, a first antenna cluster, and a second antenna cluster. The vehicle body defines a boundary between an inside of the vehicle and an outside of the vehicle. The first antenna cluster is mounted on the outside of the vehicle and is configured to operate at coverage band cellular telephone frequencies using coverage band signals. A second antenna cluster is disposed in the inside of the vehicle and is configured to operate at capacity band cellular telephone frequencies using capacity band signals.
