Abstract: Various embodiments of the teachings herein include a method for determining a target position of a surroundings sensor of a vehicle using a vehicle-side attachment element as a calibration object, wherein the sensor and the attachment element are movable relative to each other. The method includes: ascertaining a first position of the surroundings sensor in a first relative pose; moving the sensor and/or the element from the first pose to a second pose between the sensor and the element; ascertaining a second actual position of the surroundings sensor in the second relative pose; and determining the target position of the surroundings sensor by averaging the first position and the second position to form an averaged actual position and assigning the averaged actual position as the target position.

Abstract: Various embodiments include a catalyst measuring system for determining the aging of an SCR catalytic converter, the system comprising: a control device with a processor; an SCR catalytic converter for treating the exhaust gases of a vehicle; a high-frequency sensor for measuring a level of ammonia loading of the SCR catalytic converter; and an ammonia dosing system for injecting ammonia into an exhaust system of the vehicle.

Abstract: Various embodiments include a catalyst measuring system for determining the aging state of a catalytic converter comprising: an SCR catalytic converter; and a high-frequency measuring arrangement including a processor, a first antenna, and a second antenna. The first antenna is located upstream of the SCR catalytic converter in the exhaust tract and the second antenna is located downstream of the catalytic converter. The processor instructs the antennas to selectively emit and receive electromagnetic signals and evaluates the transmitted and the received electromagnetic signals to compare them with predefined threshold values. The processor determines an aging state of the SCR catalytic converter based on the comparison.
