Abstract

A device for monitoring a distance between a vehicle and object, including distance sensors mounted in the front and/or rear vehicle region(s), an electronic unit connected thereto, and a display device for visually and/or acoustically displaying distances. The electronic unit generating a full warning signal even prior to reaching the predefined minimum limiting value for an ascertained distance at an established first warning distance value which is greater than the minimum limiting value of a first sensor, if a distance, which is smaller than a first limiting value, is ascertained by a direct echo of the first sensor, the first limiting value being greater than the minimum limiting value of the first sensor, and if a distance, which is greater than a second limiting value, is ascertained by a direct echo of the second sensor, the second limiting value being greater than the minimum limiting value of the second sensor.
