A housing (10) for enclosing at least one electronic component of a motor vehicle comprises at least a first metal housing part (20) with a first circumferential connection surface (21) and a second metal housing part (30) with a second circumferential connection surface (31). The metal housing parts (20, 30) are designed to be connected to each other along a connection direction such that said circumferential connection surfaces (21, 31) lie face to face to each other in the connected state. At least one of the housing parts (20) comprises a plurality of cutting elements (22) protruding from the corresponding circumferential connection surface (21). At least a part of the cutting elements (22) have an oversize with respect to the other circumferential connection surface (31), such that the cutting elements (22) cut into the other circumferential connection surface (31) during connection of the housing parts (20, 30). The cutting elements (22) are distributed over the circumference of said circumferential connection surfaces (21, 31).

The method relates to a method for annotating data points (151, 161) in a data set, where the method comprises:obtaining (S1) a set of data points associated with an environment sampled by a vehicle sensor (110); anddetermining (S2) a static model (200, 300) of the environment based on the set of data points, wherein the static model of the environment comprises a collection of local statistical models. The method further comprises:obtaining (S3) a new data point associated with the environment;associating (S4) the new data point to a corresponding local statistical model comprised in the static model of the environment; andannotating (S5) the new data point as a stable data point in case the new data point agrees with the corresponding local statistical model.

The present disclosure relates to a method for detecting blockage of a radar sensor (105) by processing a radar signal (115, 116, 117) received by the radar sensor (105). The method comprises obtaining (S1) the radar signal (115, 116, 117), determining (S2) a range-Doppler representation (300) of the radar signal such that received radar signal energy (311) is represented as a function of distance (d0-d13) and relative velocity (v0-v7), determining (S4) predetermined azimuth angles (θ₁, θ₂, θ₃) for the radar sensor (105) and calculating (S31) a relative velocity (v0, v3, v5) for each predetermined azimuth angle (θ₁, θ₂, θ₃). The method further comprises obtaining (S5) a first distribution (301) and at least one other distribution (302, 303) of received energy (311) over distance in the range-Doppler representation (300) for a first azimuth angle (θ₁) and at least one other azimuth angle (θ₂, θ₃), generating (S7) a measure of similarity for the distributions, and detecting (S8) blockage of the radar sensor (105) if the measure of similarity satisfies a similarity criterion.
