METHOD AND DEVICE FOR ASCERTAINING AND COMPENSATING FOR A MISALIGNMENT ANGLE OF A RADAR SENSOR OF A VEHICLE

摘要

A method for ascertaining and compensating for a misalignment angle of a radar sensor of a vehicle, includes generating a first set of data which contains information about a measured alignment of the radar sensor with respect to an instantaneous movement of the vehicle; generating a second set of data which contains information about a measured alignment of the reference axes defined at the vehicle with respect to the instantaneous movement of the vehicle; ascertaining a misalignment angle by comparing the generated first set of data to the generated second set of data; compensating for the ascertained misalignment angle by changing an emission direction of the main lobe of the antenna characteristic as a function of the ascertained misalignment angle.

1. A method for ascertaining and compensating for a misalignment angle of a radar sensor of a vehicle, the method comprising:
generating a first set of data which contains information about an instantaneous movement of the vehicle with respect to an alignment of the radar sensor; generating a second set of data which contains information about the instantaneous movement of the vehicle with respect to an alignment of at least one defined reference axis of the vehicle; ascertaining, by processing circuitry, a misalignment angle by comparing the generated first set of data to the generated second set of data; and compensating, by the processing circuitry, for the ascertained misalignment angle by changing an emission direction of a main lobe of an antenna arrangement of the radar sensor as a function of the ascertained misalignment angle.
