LINBUS protocol

This some brief ‘zig zag zog’ about LINBUS protocol!

LIN is a short for, Local Interconnect Network (LIN)


For CANBUS NONSESNE

In the picture below,
a major ECU, Y, is on the major, CANBUS, network with other major ECUs, X and Z!

The major ECU, Y, forms a minor (local) network with other minor control units, a, b, c, locally🤠!
LIN is that minor, inter-connection between the major ECU, Y,  with other the minor control units, a, b, c🤷‍♂️!

Now, lets use ☝ master ECU, Y,  and minor control unit, c☝, in this demonstration below👇!

Study this picture below!  We’re using a side mirror, for example!
A) The side mirror has a function of  an indicator 🚨light!

B) The side mirror may need to be folded, in or out👌!

F) The side mirror has lane-keeping camera🧐!

C) The side mirror (the real glass😂🤣) may need to be adjusted to with the horizontal axis!

D)The side mirror (the real glass😳) may need to be adjusted to with the vertical axis!

E) The glass may need to be heated, warmed, to clear 🧻any storm that clogs glass, especially when it’s raining, snow, etc!

G) Lets eliminate the camera’s cable, G!

H) Cable, H, has only 3 wires, as You can see at, J 👇

J) Imagine, with all the those very many functions in, of, at, by the side mirror,
yet the minor control unit (that thing where letter J is🧐) in the side mirror, just gets 3 wires,

Battery Positive +ve, Ground or Negative -ve, and LINbus signal,
from the main ECU, could be the Body ECU, a.k.a BCM or whatever! 

Wiring Diagram of that mirror’s setup
D & C are motors to adjust the mirror accordingly!
E is heater to warm the mirror’s glass as to clean whatever sh*t !
B is another motor to fold the whole the mirror, in or out, seen🤔?

☝☝☝
y is the LIN communications’wire

x and z from (may be the battery directly) or from some whater power module🤷‍♂️, insha’Allah!

K) The minor control unit receives just 3 wires, but spits out billions of wires to each respective actuator or sensor!

For example in this 👇 motor control system,
b, could be straight from the battery,
then, a, the LINbus wire, from the respective master ECU, to the slave control unit (minor ECU), Y, within the motor’s ‘zig zag zeg’😂😁!
OK, whatever, just know that, the +ve & -ve could be coming straight from the battery🤷‍♀️,
BUT obviously that 1 wire is coming from the main ECU, a.k.a master ECU!

This one wire is the ujanja doing all the LINBUS magic🧐!

The following are random pick-outs on about this LIN!
👇

The main ECU, A, or the LIN master can control upto 15 minor or small or slave control units, a.k.a the LIN slaves

So, the whole LIN network😂, is upto 16 modules!

The LIN is kinda slow, and is often used in vehicles for less important communication jobs, like to control windows, wipers, air condition etc…

The LINbus uses a single wire, with a maximum length of 40 m, unlike, as compared to CANbus with its canLO & canHI two wires’ connection!

The LIN operating voltage could even be,  12V, 24V, etcV,  😁😂!

Look here👇

We tested this seat heater system blaa blaa🚽!
When You press the button for LOW heat, a lower voltage is sent out 
👇

When the middle or moderate switch is presses, middle voltage comes
👇

Sasa, when the maximum sh*t is pressed, so is maximum voltage sent out, seen🤔?
Is it kinda making sense now🤔?
One 1 wire, carrying different voltages, each voltage with it’s respective message🤷‍♂️!

HAPA UJANJA tu😊😊

…yuh done know😂😁!

Just like in the CANbus, even in the LINbus control units,
there is some transceiver module to make sense & nonsense of whatever LIN messages😎!

 

Just like in the CANBUS, even this LINBUS has those zig zag zeg resistors😜😜😂

I don’t know whatever I forgot to include, but insha’Allah, I will remember, then will ad it here, let me do few bottles😜!

May be whatever is causing You believe MUST do some nonsense to the vehicle, is some minor external problem with the sensors or actuators🤷‍♂️!

CONTROL SYSTEMS (intro)

Siku hizi almost kila kitu kinaundwa kuwa na hii blaa bla ya CONTROL SYSTEMS, mfano, AC za ofisini, nyumbani mataa yanajiwasha yenyewe, gari za siku hizi kila kitu mafundi wanazungumza ‘kontulo’ yaani control (ECU) ama kompyuta ya gari, nk!

Hapa tunaelezana kwa ufupi, maana na jinsi, au namna huu uchawi wa CONTROL SYSTEM unakuwa!

Imagine huu mfumo wa hesabu

X + 5 = Y

(5 haibadiriki, lakini X au na Y inaeza kuwa chechote)!
X ikiwa 2, ina maana Y itakuwa 7
2 + 5 = 7
Ina maana ukitaka mfumo wako uwe tu wenye 7 kama matokeo, lazima X uingize iwe 2, au na vinginevyo! Ukitaka matokeo au Y iwe 9, hapo lazima X iongezeke kuwa 4!

Tayari, hapa 5 ni control!
Huo mfumo 5 (control) kudhibiti matokeo kwenye Y(output) kulingana X (input) itakachokuwa, ni CONTROL SYSTEM wa X + 5 = Y

CONTROL SYSTEM ni mfumo ambao matokeo yanategemea maingizo!Kwa mfano wetu pale juu,
Input  ni X, Control ni 5, alafu Output ni Y!

Alafu hizi CONTROL SYSTEMS zinaundwa kwa aina au namna mbili! Kuna zile ambao hamna aja ya kuthibitisha au ku comfirm matokeo, a.k.a OPEN LOOP CONTROL SYSTEMS, alafu na zile ambao lazima, au ata matokeo yanafanya uchawi ata kwenye mainginzo, ambao ni CLOSED LOOP CONTROL SYSTEM!

Naomba, ili kueleezana viruzi tofauti kati ya hizi aina, kutumisa mfano wa ile AC ya kudhibiti ujoto chumbani au ata ikiwa gari!

OPEN LOOP CONTROL SYSTEM

Imagine, hiyo siginal ya INPUT inatokea kwenye Temperature sensor inaochunguza ujoto chumbani au ata kwenye gari, mfumo ni kwamba hiyo Temperature sensor ikipeleka umbea kwamba kuna ujoto chumbani, hapo AC itaanza, yaani itawaka tu, hata kama hakuna mtu yeyote chumbani! Sasa ndo hizi OPEN LOOP CONTROL SYSTEM!

CLOSED LOOP CONTROL SYSTEM

Sasa hiyo siginal ya INPUT inatokea kwenye Temperature sensor imeruhusu AC kuanza, lakini AC ikiwaka lazima kuna ijulishe au ipeleke umbea kwamba nimewaka! Sasa huko sehemu ndo kuna blaa blla zingine kuchunguza kama kuna watu au la, ikiwa la AC itajizima yenyewe! Huo mzunguko ndo CLOSED LOOP CONTROL SYSTEM!

Kukitokea mfano tatizo, tuseme huku AC inawaka hata bila watu au vinginevyo, ukifanya diagnosis hizo blaa blaa za OPEN LOOP detected!


GROUND, NEUTRAL, EARTH, connections explained

Hata kama EARTH na GROUND ni kama kitu kimoja, lakini ni tofauti!
Kwa kingereza ya Merikani wanasema GROUND, alafu kwa Kingereza ya Ulaya(Europe) ni EARTH, so sometimes maana inakuwa confused!

So is why we tried to explain the difference in this rubbish video!
