6.1 SmarTach
®
Functions
The following lists give an overview of the main functions
performed by SmarTach
®
.
6.1.1 General Purpose Functions
• Function access control : controls access to all SmarTach
®
functions and to recorded data, according to the type of smart
cards inserted. Each user only has access to the functions
and data which concern him. In normal use by drivers,
SmarTach
®
is in operational mode.
• Driver activity and driving status monitoring (one driver,
one co-driver)
: determines the activity under way for each
driver (Driving, Work, Availability, Break/Rest) and the driving
status (Single, Crew), according to movements of the vehicle
and activation of SmarTach
®
's keys.
• Driver manual entries : allows drivers to manually enter their
activities for the period between the last withdrawal of their
card and its current insertion, to declare the locations for the
beginning and end of their daily work periods, and to enter
special conditions for application of EEC Regulation
No. 3820/85 (out of scope, ferry/train).
• Vehicle movement management :
• measures the speed of the vehicle and the distance
travelled, from a signal provided by the speed sensor.
• executes pairing with the speed sensor connected,
allowing that sensor to be identified and authenticated.
Pairing, which is needed for each calibration of
SmarTach
®
, initialises a secure data link between
SmarTach
®
and the speed sensor.
• monitors integrity of links and continuity of exchanges
with the speed sensor, ensures its identification and
regular authentication thanks to the secure data link
established on pairing.
• Time management : constantly measures UTC date and
time, manages local time and checks time adjustment for
SmarTach
®
.
• Card insertion and withdrawal monitoring :
• monitors insertions and withdrawals of cards,
authenticates cards and identifies users,
• protects exchanges of data between SmarTach
®
and the
smart cards, guaranteeing integrity of data exchanged.
• Recording and storing of data in SmarTach
®
's memory :
guarantees read, update, storage and erasure of data
representing on average one year's activity of the vehicle.
• Recording and storing of data on the smart cards :
guarantees read, update, storage and erasure of data on the
smart cards inserted. For a driver card, such data represents
on average 28 days' activity for that driver.

security.
