Pedale elettronico/meccanico con tiro per automotive

My try: Electronic/mechanical pedal with [pull cable/tension?] for motor vehicles

See image of pedal at following link:

(pls ignore yellow highlighting)

Unfortunately I have no other context or information, in the source text there is no other reference to 'tiro', nor any information about how the pedal works.
All I have is a diagram (see link above), which is inconclusive.

I've also searched on the relevant company website for further info about the product but to no avail.

Possible meanings of tiro in this context: pull, pull cable, tension, tension spring, tensioner....I'm just guessing really :-(

Any input you can give would be much appreciated!
