Prepare Data Base | 4
The signals for speed calculation may
be available from different sources, like
MS 6 own measurement, GPS data or
via CAN received information from ABS
calculation. For MS 6 own calculation,
mechanical influenced data like number
of available sensors, front wheel drive,
number of detected increments, wheel
circumferences and dynamic correc‐
tions like corner speed application a lot
of functional options assist the calcula‐
tion of the effective vehicle speed. Dis‐
tance measure channels may be de‐
rived from speed information. For de‐
tailed information see function descrip‐
