F1-Trac
F1-Trac is a traction control system that derives directly from
Ferrari 's expertise in F1 vehicles.
F1-Trac is faster and more accurate than traditional control
systems and is capable of delaying and minimising engine torque
adjustments as required in order to ensure the desired trajectory.
The system estimates the maximum available grip in advance, by
continuously monitoring the relative wheel speed and using an
auto-adaptive operating logic. Comparing this information with
the vehicle dynamics model stored in the control system, F1-Trac
optimises the vehicle behaviour by controlling engine torque
delivery.
Important note
F1-Trac does not
work when the Manettino is set to
CT OFF
and ESC OFF driving modes.
The main feature that distinguishes the F1-Trac system from a
traditional traction control system lies in its ability to estimate grip
level accurately which allows the driver to make full use of the
vehicle's performance driving potential.
The
F1-Trac system guarantees:
- maximum traction when coming out of bends;
- driving stability and ease even under extreme driving conditions;
- driving comfort.
On this vehicle, integration of the
F1-Trac
and E-Diff 3 systems
ensures maximum performance and stability.
E-Diff 3
The vehicle is equipped with an electronic differential, working on
the rear axle, which continually performs a variable check on the
locking between the two axle shafts.
The electronic differential system, integrated with
F1-Trac traction
control, is capable of improving:
- performance;
- directional stability of the vehicle;
- active safety even when close to grip limit;
- driving comfort and handling.
The system is based on the analysis and forecast of vehicle
performance in all possible conditions. This is done by continually
monitoring the pressure of the clutch actuator on the differential.
The input signals are the dynamic parameters of the vehicle that the
control system translates into a torque difference between the two
driving wheels.
On bends, the electronic differential can:
- stabilise the vehicle when the accelerator pedal is released by
locking the rear axle;
- control vehicle dynamics by locking the differential according to
lateral acceleration and vehicle speed;
- maximise vehicle stability and, at the same time, acceleration on
bends by locking the differential according to lateral acceleration,
speed, engaged gear and torque produced by the engine.
To obtain these results, the electronic differential system interacts
with the F1-Trac , ESC and ABS systems, F1 gearbox and
suspension damping control.
