Sorry... aber das ist freundlich formuliert... Unsinn
Ist kein Unsinn. TTC ist nicht nur das abschalten von ASR. TTC, Torque Transfer Control, kann nur das tun, was die Name eindeutet, durch das Rad zu Bremsen wo kein Grip ist. Damit wird mehr Power zu das andere Rad geschickt, wo es Grip gibt. Bis diese auch Grip verliert, dann wird ohne ASR das Gummi zur Rauch. TTC ist ein softwaretrick die einen mechanische Sperdifferenzial emuliert. Wenn ein richtige mechanische Sper anwesend ist, ist TTC eigentlich ohne funktion, naja der ASR wird immer noch weitgehend runtergefahren.
In English die ganze Beschreibung van TTC: (mit dank an Modified Abarth)
I have just been asked for a description of TTC.
The function of TTC is to equalise the torque applied to each front wheel, across the front axle simulating the characteristics of a conventional (mechanical) limited slip differential.
TTC is a software function integrated within the Bosch 8.1 ESP. It is a dynamic system designed to alter the cornering responsiveness of the Abarth 500 away from the standard settings and as such, the default setting of this system is OFF.
To engage TTC the driver must activate the system via the button on the dashboard. Once the TTC button has been pressed, the message “TTC connected” appears temporarily on the instrument display, and the TTC button LED remains illuminated. The car is returned to its normal settings by again pressing the TTC button whereupon the message “TTC disconnected” appears on the instrument display and the TTC button illumination is extinguished. Equally, once the vehicle ignition is switched off, the TTC system is also switched off and the vehicle will always restart in its default state of TTC OFF. The driver must always consciously select the TTC function.
When cornering in a car without TTC, the weight of a vehicle transfers away from the inside front wheel and as power is applied, this (unloaded) wheel will lose traction and begin to spin. At this point most conventional safety systems would attempt to control this by significantly reducing engine power resulting in a loss of momentum.
TTC prevents the inside front wheel from spinning and retards its rotation by accurately applying the brake to that wheel. This transfers the torque across the front axle, to the outside front wheel which continues to drive the car and prevents a loss of momentum and improved responsiveness.
TTC function shall be realised through the following components:
- ESP electro hydraulic unit
- 4 Wheel speed sensor
- Throttle position sensor
- Steering angle sensor
- Lateral acceleration sensor
- Yaw rate sensor
TTC is more effective in faster corners where equalised torque between the two driven wheels can improve the speed and agility of the car. For this reason it is possibly more suited to Trackday situations where drivers are better able to explore the abilities of car and driver within the safety of a circuit environment.
It must be stressed that irrespective of whether TTC is on or off, the remaining active safety systems (ABS/ ESP/ ASR/ etc…) remain operational. These are active at all times and during the recent training events we demonstrated the car by driving it in a figure of eight shape and noticed how it could be kept close the cones, even driving at reasonable speed around such a tight radius. During this demonstration the TTC system was OFF, and the system that was holding the car on the tight line around the cones was the standard traction control system which is the default system of the car.
The reason that is was possible to provoke the car into pushing wide with the TTC on was because TTC allows both front wheels to drive the car forward, with less reduction in engine power than in the default mode. It is then up to the driver to modulate the power delivery, something which we were not doing during the demonstration as the emphasis was on demonstrating the two systems under extreme conditions
Es ist sicherlich eine ganz andere Liga. Aber beide haben ihre Charmen. Der AMG ist muhelos unheimlich schnell, der Abarth macht mehr mit dem Herzschlag weil es mehr emotionen aufruft. Beider machen viel Spaß und der Abarth geht nicht mehr weg.
