Embodiment Construction

[0021] figure 1 A schematic sketch of a first vehicle environment sensor adjustment or calibration device 2 is shown.

[0022] The first vehicle environment sensor adjustment or calibration device 2 comprises a motor vehicle 7 parked on the running tracks 4 and 6 of the measuring field together with a chassis measuring device. To simplify the illustration, only the wheels 8 , 10 , 12 and 14 of the motor vehicle 7 are shown, and the dimensions of the body of the motor vehicle 7 are only indicated by the outline drawn with dashed lines. The front and rear axles of the motor vehicle 7 are shown by dashed transverse lines. The geometrical travel axis 64 is shown as a dashed arrow which extends from the center of the rear axle to the center of the front axle. The motor vehicle has a vehicle environment sensor 15 approximately in the middle of its front, which is to be adjusted or calibrated by means of a first vehicle environment sensor adjustment or calibration device 2 .

Abstract

A method according to the invention for adjusting or calibrating a vehicle surroundings sensor (15) comprises the steps of: attaching at least one target pair (20, 22) to the rear wheels (12, 14) of the motor vehicle (7); recording the target pair (20, 22) using at least one measuring unit (32, 46) and determining the vehicle axle (64) from the recording; placing at least one target (16, 18) in a known position relative to a vehicle surroundings sensor adjustment or calibration element (62); recording the target (18) placed at the vehicle surroundings sensor adjustment or calibration element (62) using the at least one measuring unit (32, 46) and determining the angular position of the vehicle surroundings sensor adjustment or calibration element (62) relative to the vehicle axle (64); aligning the vehicle surroundings sensor adjustment or calibration element (62) relative to the vehicle axis (64); and adjusting or calibrating the vehicle surroundings sensor (15) relative to the vehicle axis (64).

Description

technical field [0001] The invention relates to a method for adjusting or calibrating a vehicle surroundings sensor and a device for adjusting or calibrating a vehicle surroundings sensor. Background technique [0002] So-called driver assistance systems are currently being used in an increasing number of motor vehicles, which monitor the vehicle environment and provide corresponding information to the driver. Some systems even actively intervene in driving operation and independently brake or accelerate the vehicle. Other systems monitor the position of the vehicle relative to the roadway, for example taking into account roadway markings. As soon as the vehicle approaches the edge of the roadway, the driver can be informed of this acoustically and / or visually. [0003] These driver assistance systems must at least be oriented relative to the axis of travel of the motor vehicle. They must therefore be calibrated or adjusted at specific intervals. Such a calibration or ad...
