Maneuver assist

How it works

The maneuver assist supports the driver when parking or manoeuvring and when driving forwards or reversing at a low speed. Its

task is to use braking interventions to help the driver avoid collisions with static obstacles. If the vehicle has been braked to a

standstill due to an obstacle being detected, the maneuver assist is deactivated temporarily if the driver then continues to drive

towards the obstacle. This allows the driver to “override” the system, since there is no second braking intervention.

The maneuver assist only works when the parking aid is switched on at speeds of between -10 km/h and +10 km/h.

The maneuver assist is a new Audi driver assist system. It is offered in models whose electronic equipment is based on the second

generation of the MLBevo platform. These are as follows:

›

Audi A8 (type 4N)

Audi Q8 (type 4M)

Audi A7 (type 4K)

Audi Q7 (type 4M)

Audi A6 (type 4A)

Audi e-tron (type GE)

Audi e-tron GT (type F8)

PR numbers

Vehicles equipped with the maneuver assist are also always equipped with the park assist plus. For this reason, the maneuver assist

does not have its own PR number. A vehicle is equipped with the maneuver assist if one of the following three PR numbers is

included in its PR number list: FT1, FT2 or FT3. These are the PR numbers for the different versions of the park assist plus.

Activation

The basic requirement to activate the maneuver assist is that the “maneuver assist” option in the MMI menu for the parking aid is

set to “on”.

The maneuver assist is activated when the driver switches the park assist system on by performing one of the following two ac-

tions:

›

Engaging reverse gear

Pressing the parking aid button

By contrast, when the parking aid is activated automatically as a result of driving forwards slowly, the maneuver assist is not acti-

vated. In this case, the driver can activate the system manually by tapping the function symbol displayed on the MMI.

Maneuver assist displays

684_099

The current system status of the maneuver assist is indicated on the MMI's parking system display via the function symbol for the

maneuver assist. This is shown on the roof of the vehicle displayed on the MMI. In addition, four segments are shown around the

vehicle at the front left, front right, rear left and rear right.

Sensors and hardware

The software of the maneuver assist is integrated in driver assist systems control unit J1121. The maneuver assist function re-

quires the following sensors:

›

12 sixth generation ultrasonic sensors

4 overhead view cameras, the images from which are processed in control unit J1121

Due to the required sensors, version C of driver assist systems control unit J1121 is required for the system.

Reads in the sensor signals from the ultrasonic sensors and evaluates them

Receives the camera images from the four overhead view cameras and processes them

Extracts objects from the camera images received from the overhead view cameras and localises them within the technical limits

Enters all available sensor data in a shared internal map (sensor data fusion)

Initiates braking to bring the vehicle to a standstill in critical situations via control unit J104

Initiates corresponding displays for the maneuver assist on the MMI and in the instrument cluster

Keeps the vehicle stationary after a protective braking intervention has brought it to a standstill

Automatic gearbox control unit J217

›

Transmits the current transmission position (the maneuver assist is always deactivated in transmission position N so as to

avoid protective braking when the vehicle is inside a car wash)

Adaptive cruise control unit J428

›

Transmits whether the adaptive cruise assist is currently active. The maneuver assist must be deactivated when the adaptive

cruise assist is active.

Introduction

The park assist plus makes parking incredibly convenient. It guides the vehicle into parking spaces parallel or perpendicular to the

road by taking over the steering, acceleration, braking and changes of transmission position.
