Ball joint for a vehicle

The invention relates to a ball joint (1) for a vehicle, having a housing (2) and a in an axial direction (A) extending and a joint ball (4) comprising the ball pivot (3) with its joint ball (4) pivotably in the housing (2) is mounted and through an opening (8) of the housing (2) also extends, and at least one sensor (6), which serves a tilting angle (α) between the ball pin (3) and the housing ( to detect 2), wherein the joint ball (4) has a flattened portion (5), wherein the at least one sensor (6) is a distance sensor which is disposed (on a wall 7) of the housing (2) and the flattened region ( 5) of the joint ball (4) is opposite, and wherein the at least one sensor (6) is oriented such that the sensor (6) having a predetermined measuring direction a distance (d) relative to the flattened portion (5) is detected in order to derive the tilt angle (α) to close, wherein the measuring direction so is designed such that an injective mapping between the tilt angle (α) and to be detected distance (d) is produced.
