A system and method for aligning the beam path of a beam-emitting sensor arranged on a motor vehicle. Convenient and nevertheless highly precise setting of the beam direction of the beam-emitting element is possible if, when the vehicle is stationary, an external aligning beam propagating along or parallel to an actual direction of travel of the motor vehicle 1 hits a strictly planar surface on the sensor which reflects the aligning beam, the incident aligning beam and the reflected aligning beam are made to overlap as a result of the position of the sensor being changed.

Method and apparatus for aligning a beam path for a beam-emitting sensor

A method for determining a control object which is situated in an expected traveling corridor of a vehicle whose distance from the control object is measured and adjusted to a desired distance. The method for reliably determining the control object which enables reliable distance control even in the event of momentary and sudden changes in the traveling corridor of the vehicle determines an object corridor which covers the traveling corridor and is wider than the traveling corridor of the vehicle, control with respect to the control object being effected as long as the latter stays in the object corridor of the vehicle.

Method and system for determining a regulator object

A method and system for the determining in advance of the travel corridor of a motor vehicle for an automatic system for establishing a safe tailing distance in which a signal corresponding to the speed is used to determine a turning radius of the motor vehicle, the travel corridor being determined from the turning radius. For the exact determination of the travel corridor of the motor vehicle, and in order sufficiently to take into consideration the travel dynamics of the motor vehicle, the speed of at least two wheels of the vehicle are measured and the yawing of the vehicle determined from the difference between the two wheel speeds.

Method and system for the determination in advance of a travel corridor

A method for the exact determination of the speed of a rotating part, in particular the speed of the wheel of a motor vehicle, in which discontinuities present on the circumference of the rotating part are scanned without contact, an electric pulse being produced upon the detection of each discontinuity and the number of pulses thus produced being counted. In order definitely to be able to determine the dynamism of a rotating part without manufacturing tolerances of the incremental disks influencing this, the period of time within which all pulses of the rotating part are counted precisely once is determined, and the speed of the rotating part is determined therefrom.
