Histogram
Measured values relating to braking pressures, axle loads and speeds are con-
stantly captured during operation.
Histograms represent the frequency of events with the respective measured values.
This enables one, for instance, to determine whether the driver applied the brake in
a forward-thinking manner, softly or rather more sharply on the basis of the distri-
bution of brake actions in classified braking pressure ranges.
The following histograms can be retrieved:
Aggregate load (sum of all axles)
Recording the kilometres travelled per combined
multi-axle class
Axle load (axle load for one axle)
Recording the kilometres travelled per combined
axle load class
Braking time
Recording the braking time per class and the maxi-
mum occurring pressure
Control pressure
Recording the braking requests per class and the
maximum occurring pressure
Braking pressure
Recording the executed braking pressures per class
A detailed description of the histograms can be obtained from the ODR Tracker
operating instructions, see chapter 4 ‘Introduction’, page 12 => ‘More inform
ation’
section.
Event recorder
The event recorder stores the number of events (a maximum of 200), i.e. braking
system events.
Each event is saved in the TEBS E Modulator, together with the time of occurrence
(only in SmartBoard) and the odometer reading at that time.
Such events can include:
• ABS interventions
• RSS interventions
• Warning display illuminated
• Messages
• Manual deactivation of TailGUARD
• Immobilizer events
• events definable by GIO parameter settings (e. g. if a connected door contact
switch indicates the opening of a door)
Up to 700 events are stored and these also include any diagnostic
messages.
