Traction Control System (TCS)

[udengfahlawi]

i wonder if got playstation game for drag race or not?....

 

[hattech-v]

got laaa... sure u never play game b4..

 

[udengfahlawi]

err....i played PacMan before....and Raiden also.....plus Raiden II...

 

[hattech-v]

no wonder laa...

 

[patrickchong]

tcs will not help in drag... abc does.. haha
tcs is to enable super powerful engine transfer power to the wheel by controlling the wheel spin...

main GT3/4 la wey....
haha

u mean tcs is for super powerful engine transfer power to the wheel with the minimum wheel spinning to avoid power lose on spinning ? hmmmm how did it function to control the wheel spin ? rpm ? AFR ? controling in engine part or transmission? braking system ?

it employs the braking system (ABS) by braking the wheels individually when it detects slip.

:hmmmm: as i know, ABS is not functionning by braking the wheel, is unbraking(release) any of the wheel following the wheel speed which detect by wheel speed sensor tat located at the drive shaft cv-joint. And as wat u say TCS employs the ABS braking the wheels when detected slip, ABS already functinning for avoid slip, wat for another additional system (TCS) for ABS? no offence

i also heart tcs system from initial-d cartoon comic, but dun understand

 

[fobs]

not unbraking,... what bien means by the ABS are the brakes,... not the ABS itself,... but when the brakes apply itself, with ABS effect,...

urrghhh myself,... haha!

That is the beauty of the ABS system. Not only it enables you to control the car in extreme situations by preventing tyre lock, it can also function the other way round, since it has the ability to control any individual wheel.

TCS is the extension of ABS. Without ABS, TCS will not function. You see many fancy 3-letter acronyms in the market, but all of them have one core. ABS.

ABS and TCS stop a wheel from slipping in a straight line, but when it comes to curves, you need something else, a stability assist system.

From ABS, you get TCS, BA (Brake assist), ESP, DSC, DTC, any many more.

Be it in mechanical form, or electronic. The software that governs the system is what makes each system unique. And effective. No two systems are alike, unless the car manufacturers employ a single company, namely Bosch.

But nowadays, the ESP system is more intelligent, by controlling the amount of power sent to the wheels, electronically, by employing clever diffs and cutting power or adding more power to any wheel.

ABS is then left to the role of merely preventing the wheels from locking up and also brake any individual wheel when things go wary, or when you run out of skill.

hahah i also arghhh my self

but i jz found some source, i would like to share it, but duno its correct or not:hmmmm: :sleep:

The steerability of a vehicle is not only lost when the wheels lock up on braking; the same effect arises if the wheels spin when driving off under severe acceleration. Electronic traction control has been developed as a supplement to ABS. This control system prevents the wheels from spinning when moving off or when accelerating sharply while on the move. In This way, an individual wheel which is spinning is braked in a controlled manner. If both or all of the wheels are spinning, the drive torque is reduced by means of an engine control function. Traction control has become known as ASR or TCR.

3 method of tractive force control.

throttle control,
this can be via an actuator, which can move the throttle cable or , if the vehicle employs a drive by wire accelerator,then control will be in conjunction with the engine management ECU. this throttle control will be independent of the driver's throttle pedal position. This method alone is relatively slow to control engine torque.

Ignition control
if ignition is retarted the engine torque can be reduced by up to 50% in a very short space of time. The timing is adjusted by a set ramp from the ignition map value.

braking effect
if the spinning wheel is restricted by brake pressure the reduction in torque at the affected wheel is very fast.Maximum brake pressure is not used to ensure tat passenger comfort is maintained.:sleep:

there you go.

hope that clarifies up things.

 

[kapucin]

thanks otai²
for ur good info..

bro hattech... the ECU like thing in this pic is the ECU for tcs and abs ah?

ya.. the car chassic looks new and clean...
