Audi pre-sense
Audipresense is, within its system parameters, able to initiate
actions to protect the occupants and other road users in certain
critical situations. For this purpose, the vehicle and its occupants
are prepared for a potentially imminent collision.
This is made possible by networking the various in-car systems.
The systems send data continuously to the data bus. Other control
units are able to evaluate this information and take appropriate
action.
Audipresense is available in the following versions for the
AudiQ7.
Depending on market, Audipresensebasic/rear and
Audipresensecity may be standard equipment. If this is not the
case, Audipresensebasic, presensecity, presenserear and
presensefront are optional.
Please note that Audi pre sense cannot prevent collisions. It serves
only to assist the driver and it can reduce the severity of the colli-
sion. It should also be noted that not all objects or lane makings
can be detected by the sensor or by the camera.
The individual functions of Audipresense are described in greater
detail below.

With Audipresensebasic, the following actions can be initiated:
• Belt slack reduction
• Partial or full tensioning of the electrically reversible seat
belt tensioners
Definition and function of belt slack reduction system for reversible seat belt tensioners
In certain situations, e.g. when wearing a thick winter jacket, it
may be the case that the seat belt is not tight fitting to the body
after the reversible seat belt tensioners deploy. In such a case, the
mechanical unreeling force of the automatic seat belt retractor is
less than the force required to compress the thick winter jacket.
The distance which the seat belt can travel until it fits the front
occupants perfectly is referred to as "belt slack".
