4.2.2 Buffer for v-recording
In two special cases, the buffer for v-recording will serve to store
detailed speed data:
• A large deceleration (a < -3 m/s
2
; such as hard braking, collision
with an obstacle)
– The detected speed values (4 speed values per second) will
be recorded and saved each second for the time period of
one minute before until one minute after the delay.
• Vehicle motionless
– The detected speed values (4 speed values per second) will
be saved each second for the time period of one minute
before until one minute after the vehicle stopped moving.
