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.

Method and device for determining a target position of a surroundings sensor of a vehicle

Various embodiments include a catalyst measuring system for on-board diagnostics and for determining the aging of an SCR catalytic converter for a vehicle comprising: a processor; an SCR catalytic converter for purifying exhaust gas of the vehicle; a high-frequency sensor for determining the ammonia loading of the SCR catalytic converter; a NOx sensor for sensing the NOx concentration downstream of the SCR catalytic converter; and an ammonia dosing system for injecting ammonia into an exhaust system of the vehicle. The control device instructs the ammonia dosing system to inject ammonia selectively into the exhaust system at a plurality of different dosing rates. The control device evaluates data received from the NOx sensor and of the high-frequency sensor to calculate the ammonia dosing rate.
