A method for adjusting the sensitivity of ultrasonic sensors for detecting the distance of objects from a vehicle. A sensor sensitivity is set selected so that a sonic lobe is transmitted which has an intersection with the ground. A measurement is determined using the sensor, objects in the surroundings of the vehicle having a greater distance from the vehicle than the distance from the sensor to the intersection of the sonic lobe with the ground, so the distance from the sensor to the intersection of the lobe with the ground is detected as being the shortest distance from an object. The sensitivity of the sensor is set as a function of the distance between the sensor and the intersection of the lobe with the ground, so after sensitivity is set, the lobe, at its point closest to the ground, does not fall below a specified distance from the ground. |
