The system includes a blocking device capable of moving along the vehicle; a blocking element attached to the blocking device capable of being positioned against a vehicle tire such that the vehicle is blocked; a blocking element extension mechanism configured to extend the blocking element from a retracted position to an extended position; height adjusting means for height adjustment of the blocking element; and calculation means for calculating the desired height of the blocking element with the blocking element in an extended position such that the blocking element is used for determining the position of the vehicle tire. ## Claims ### Claim 1 A system for blocking a vehicle, comprising: a blocking device capable of moving along the vehicle; a blocking element attached to the blocking device capable of being positioned against a vehicle tire such that the vehicle is blocked; a blocking element extension mechanism configured to extend the blocking element from a retracted position to an extended position; a height adjuster configured to adjust a height of the blocking element; and a calculator configured to calculate a desired height of the blocking element with the blocking element in an extended position such that the blocking element is used for determining the position of the vehicle tire. ### Claim 2 (depends on 1) The system according to claim 1, wherein the extension mechanism comprises a spring element configured to extend the blocking element after passing a vehicle tire. ### Claim 3 (depends on 1) The system according to claim 1, wherein the height adjuster comprises a height adjustment drive configured for changing the height of the blocking element. ### Claim 4 (depends on 1) The system according to claim 1, further comprising: an anti-roll mode, wherein the blocking element engages the tire at a first height; and a locking mode, wherein the blocking element engages the tire at a second, greater height. ### Claim 5 (depends on 1) The system according to claim 1, further comprising a guide track disposed along a driveway for guiding movement of the blocking device. ### Claim 6 (depends on 5) The system according to claim 5, wherein the height adjuster comprises a guide track height adjustment drive configured for changing the height of the guide track. ### Claim 7 (depends on 6) The system according to claim 6, wherein the drive comprises a first lifting mechanism for lifting a first end of the guide track, a second lifting mechanism for lifting a second end of the guide track, and a drive connection configured for connecting the first lifting mechanism with the second lifting mechanism. ### Claim 8 (depends on 1) The system according to claim 1, further comprising a self-propelled carrier configured to move the blocking device. ### Claim 9 (depends on 1) A loading/unloading system provided with a system according to claim 1. ### Claim 10 A method for blocking a vehicle comprising the steps of: providing a system and/or a loading/unloading station; moving a blocking device along the vehicle; extending a blocking element with a blocking element extension mechanism after passing a vehicle tire; calculating a desired height of the blocking element with a calculator after extending the blocking element; and positioning the blocking element at the desired height with a height adjuster. ### Claim 11 (depends on 10) The method according to claim 10, wherein the desired height is calculated from vehicle tire material positions determined from contacting the vehicle tire at two or more heights with the blocking element in the extended position. ### Claim 12 (depends on 10) The method according to claim 10, further comprising the step of providing an additional force on the blocking element against the vehicle tire to compensate vehicle tire movement. ### Claim 13 (depends on 12) The method according to claim 12, wherein the additional force is applied periodically. ### Claim 14 (depends on 10) The method according to claim 10, further comprising the step of choosing to position the blocking element in an anti-roll mode or in a locking mode. ### Claim 15 (depends on 11) The method according to claim 11, further comprising the step of choosing to position the blocking element in an anti-roll mode or in a locking mode. ### Claim 16 (depends on 12) The method according to claim 12, further comprising the step of choosing to position the blocking element in an anti-roll mode or in a locking mode. ### Claim 17 (depends on 2) The system according to claim 2, wherein the height adjuster comprises a height adjustment drive configured for changing the height of the blocking element. ### Claim 18 (depends on 2) The system according to claim 2, further comprising: an anti-roll mode, wherein the blocking element engages the tire at a first height; and a locking mode, wherein the blocking element engages the tire at a second, greater height. ### Claim 19 (depends on 3) The system according to claim 3, further comprising: an anti-roll mode, wherein the blocking element engages the tire at a first height; and a locking mode, wherein the blocking element engages the tire at a second, greater height. ### Claim 20 (depends on 3) The system according to claim 3, further comprising a guide track disposed along a driveway for guiding movement of the blocking device and wherein the height adjuster comprises a guide track height adjustment drive configured for changing the height of the guide track.
