A marker used to detect an axial deviation of a radio wave axis Ar of a radar unit is provided in front of the radar unit and outside a radar field of view range set based on a filed of view angle θ of the radar unit on a vehicle. A relative position between the radar unit and the marker is different between before and after an axial deviation of the radio wave axis Ar of the radar unit occurs. Thus, an axial deviation (an amount Δ0 of axial deviation in an azimuth direction and an amount Δα of axial deviation in an elevation angle direction) of the radio wave axis Ar of the radar unit can be detected by obtaining a difference in marker detection position before and after the axial deviation by the radar unit.

According to a first aspect of the present inventive concept there is provided an autonomous mobile cleaning robot, comprising: a radar sensor configured to scan a surface, during a movement of the robot along the surface, by transmitting radar signals towards the surface and acquiring, at different positions along said movement, radar responses from the surface, a radar signal processor configured to extract one or more features of each acquired radar response from the surface, and a controller configured to control an operation of the robot based on the extracted one or more features.

A simulation method for predicting a false positive for a predefined region outside a desired field of view of a radar sensor. Calculated primary rays having a respective primary energy level represent the radar signal. Reflected rays are calculated based on the primary rays or other reflected rays and based on geometrical data for at least one item within the predefined region. An energy level is determined for each reflected ray based on an estimated reflectivity of the at least one item and based on the primary energy level of the respective primary ray, and a clustering level for the reflected rays is determined based on distances of the respective reflection points. A probability for an occurrence of a false positive is estimated based on the energy level and the clustering level.

Vehicle body panels and systems are described. A vehicle body panel may include at least one layer of material defining the vehicle body panel and one or more than one electronic device, where a portion of each electronic device is embedded within one or more than one of the at least one layer of material. Each electronic device may communicate with a control system or a vehicle control unit of the vehicle to support an advanced-feature functionality of the vehicle. At least one electronic device may include a first portion embedded within the one or more than one of the at least one layer of material. The first portion may be couplable to a second portion, not embedded within the material, where the first portion upon being coupled to the second portion communicates with the control system or the vehicle control unit of the vehicle to support the advanced-feature functionality.

A sensing system of a vehicle includes a control and a mounting carrier that supports a plurality of sensor units. The mounting carrier is configured to be disposed at the vehicle so that the plurality of sensor units have respective fields of sensing exterior of the vehicle. The mounting carrier includes structure to support the sensor units at an exterior structure of the vehicle so as to provide a desired field of sensing. The mounting carrier includes an electrical connector that is configured to electrically connect to an electrical connector of the vehicle. The sensor units are electrically connected to a circuit element that is electrically connected to the electrical connector of the mounting carrier. The control, responsive to outputs of the circuit element, determines the presence of one or more objects exterior the vehicle and within the field of sensing of at least one of the sensor units.

An automotive radar installation structure that allows a radar main body to be assembled to a vehicle in a simple arrangement and with stable performance, and a fascia retainer to attach a bumper fascia as an exterior part of a bumper to the vehicle. The structure includes a flat solid shape radar main body 122 and a transmission and/or reception surface to transmit/receive radio waves, and a fascia retainer 120 to attach a bumper fascia 108 of a rear bumper 104 of the vehicle to the vehicle main body. The fascia retainer 120 has a fixation portion 150, and a radar installation portion 128 in the vicinity of the fixation portion 150 having a recessed shape to receive the radar main body 122 so that the transmission and/or reception surface 130 faces outward of the vehicle.
