Appendix C

Parameter error

significance and functionality
implications

C.1

Camera height

The  range  measurement  accuracy  of  the  system  is  proportional  to  the
camera  height  error.  E.g.,  1  cm  error  in  camera  height  of  2.2  meters
implies  a  ~0.45%  error  in  range  and  headway  measurement
(insignificant).

C.2

Lateral distance to the front wheels

An error in this parameter will cause the warning to be moved by the
same amount. For example, if the distance to right wheel is off by 1 cm
then the warning will be issued with an error of 1 cm from the lane
marking line (insignificant).

C.3

Distance to the front of the vehicle

The headway calculation subtracts this value from the camera-to-target
distance. For example, an error of 10 cm in the distance of the vehicle
bumper to the camera will result, for a target in the range of 30 meters,
in a 0.33% error in range measurement. For European trucks this
parameter can be assumed to be 0.
