Ferrari has just patented a new steering system which could provide more accurate steering than previously and currently available.
In the patent, it is indicated that in a car with ‘normal’ power steering, there is a ‘transmission error’ when the driver turns the steering wheel to when the front wheels actually move. This means that there is a small amount of slack between the wheel column and the steering linkage. This also means that there is inconsistent effort when turning the steering wheel.
What Ferrari’s newly patented steering system does is eradicate this ‘transmission error’ as well as tiny changes in steering effort required to make the car turn. The system works with the car’s computers recognising and calculating the torque and angle of the steering wheel during turning. This information is forwarded to an electrical servomechanism which then applies force to the steering system.
The key of the system is that while it doesn’t reduce the effort to turn the steering wheel, it ensures that the same effort is always applied no matter of the conditions.
Final details about the system and whether and if so, when it will be applied to road cars is unknown. All the company did was confirm that it will not comment on its patents.
