A method is described in which the correction of the detection range of a distance sensor, which is installed with an eccentricity laterally offset with respect to the central axis of a motor vehicle. In order to correct the detection range, a correction angle (a) is used, with which the eccentricity (y) of the distance sensor (3) is corrected at the time of its installation. Thus the distance sensor (3) is not aligned parallel to the longitudinal axis of the vehicle, but to its central axis. Thus, the detection range is advantageously covered approximately symmetrically to the longitudinal axis of the vehicle. The correction angle (a) is determined either empirically, via appropriate test measurements, or mathematically.
A method for correction of the detection range of a distance sensor (3), which is installed with an eccentricity (y) laterally offset with respect to the central axis (M) of the motor vehicle (1) and detects an obstacle (2) within its detection range at an angle (b) and determines its distance (d) and/or position relative to the motor vehicle (1),
The method according to one of the preceding claims, wherein the correction angle (a) is determined according to the equation
The method according to one of the preceding claims, wherein the correction angle (a) is selected so that it covers approximately the same detection range for a right turn and a left turn.
The method according to one of the preceding claims, wherein the correction angle (a) is up to approximately 1°.
The method according to one of the preceding claims, wherein the correction angle (a) is permanently adjusted at the time of installation of the distance sensor (3) in the motor vehicle.
Use of the method according to one of the preceding claims for a cruise control system.
