1. velocity signal RDE requirement | Norbert Ligterink

2. Velocity signals required quality for determining acceleration
wheel speed gives
accurate and robust
signal (e.g. ABS)
GPS signal
is poor, deviating,
and absent 5%-15%
of the time
OBD signal
often “stylized”
optical signal
can be improved

3. Independent determination of velocity based on wheel speed calibrated with GPS
alternative setups
possible with
appropriate
accuracy
requirements
typical tachometer
