The CAN commun ica t ion system is describe d below .
•Each ECU communicating with CAN pe riodically
se
nds several sensors’ inf o rmation on CAN bu s
as dat
a frame (calle d periodical send ing d a t a ).
For furt
her det ails, co nsult the dat a frame sectio n
.
•ECUs requirin g dat a on CAN bu s can receive
dat
a fra m es sen t from each ECU simult aneo usly .
•The dat a se nt from each ECU condu cting CAN
co
mmunicatio n is transmitted at 10-100 0 msec
in
terva l dep endin g on n e cessity of dat a.
NOTE: In the f i gure ab ove, th e dat a frame A is trans-
mitted in "a" intervals, while the d a t a frames B
and
C are tran smitted at int e rvals "b" and "c,"
respective
ly .
•A single ECU tra n smit s multiple dat a frames.
•When dat a frames conf lict with o ne ano ther
(when
plural ECUs tr ansmit signals simu lt ane
-
ously), data is prioriti sed for transmission b y
mediat
ion, t herefore , plu r al da t a frames are not
se
nt simult aneously . F o r furthe r det ails, consult
the
mediatio n se ctio n
.
•Data is transmitted no t by the conve n tion al volt-
age-using method b u t by volt a ge pot entia l dif f er-
ence. For further det ails, consu l t the section on
CAN
bus volt ag e transformation
.
•Reliability of each ECU transmitting sig nals via
CAN
commun ica t ion is secu red by several error
det
ection and reco very processes. For furth e r
det
ails, consult the sections on error detection
and
sy stem rec o very
.
MEDIA T I O N
Because ea ch ECU transmit s dat a indepe ndently o n
the CAN bus,
there a r e ca ses of da t a collision whe n
multiple dat
a frames that ECUs at temp t to tran smit
simult
ane ously (if mu ltiple ECUs tran smit at n early
the same
moment). At th is moment, p r ocessing of
the ECUs atte
mpting tra n smission is performed in
the followin
g way .
1.Dat a frame with high priority is tra n smitted first
accord ing to ID cod e s memo rize d in dat a frames.
2.T r ansmission of lo w-p r iori ty dat a (dat a frames) is
suspe nded b y the issuin g ECUs until the bus
clears (when no transmission da t a exist s on the
CAN bus).
NO TE: If th e su spen ded st a t e co ntinu e s fo r a sp e-
cific time, new d a t a (dat a frame content ) is cre-
ated and sent.
3.ECU cont aining suspende d dat a fra m es trans-
mits the dat a when t he bus become s available .
NOTE: The re is enou gh ca p a city on t he CAN bus,
