Abstract: The present invention refers to a method for estimating an intrinsic speed of a vehicle using a vehicle radar system with at least one radar sensor (4) for monitoring the surroundings of the vehicle (1), the method involving transmitting a radar signal via a transmission antenna of the radar sensor, receiving one or more reflected wave signals via a receiving antenna of the radar sensor, the reflected wave signals being the radar signal reflected by one or more objects, calculating an unambiguous Doppler velocity (VD), wherein the unambiguous Doppler velocity (VD) is calculated by the measured ambiguous Doppler velocity (VD,CoG) and a Doppler hypothesis (VDHypo), calculating a host-kinetic information (?) of the vehicle (1) by using the unambiguous Doppler velocity (VD), determining an estimation of the intrinsic speed of the vehicle from the host-kinetic information (?).

Abstract: A method for detecting a screening of a sensor device of a motor vehicle by an object. The method includes receiving at least one echo signal, captured by the sensor device, that characterizes a spacing between the sensor device and the object, determining a capture region for the sensor device based on the at least one received echo signal, checking whether the capture region is being screened by the object at least in some regions, assigning the at least one echo signal to a discrete spacing value from multiple discrete spacing values, determining, for each discrete spacing value a power value based on the echo signal, and deciding, by a classifier based on the power values, whether a predetermined proportion of the capture region is being screened by the object.

Abstract: The invention relates to a method for detecting a screening of a sensor device (4) of a motor vehicle (1) by an object (8), in which at least one echo signal, captured by the sensor device (4), that characterizes a spacing between the sensor device (4) and the object (8) is received (S1) by means of a computing device (3), a capture region (E) for the sensor device (4) is determined, and on the basis of the at least one received echo signal it is checked whether the capture region (E) of the sensor device (4) is being screened by the object (8), at least in some regions, wherein the at least one echo signal is assigned by means of the computing device (3) to a discrete spacing value (B1, B2, B3) from a plurality of discrete spacing values (B1, B2, B3), for each of the discrete spacing values (B1, B2, B3) a power value (P) is determined (S2) on the basis of the echo signal, and on the basis of the power values (P) a decision is made by means of a classifier as to whether at least a predetermined proportion of
