My possibly wrong interpretation, but using the wording from the website and manual:
italics are text from the owner's manual, website text is noted as such
From BMWNA Ordering Guide:
Driving Assistance Professional Package
• 5AR Extended Traffic Jam Assistant for limited access highways
Extended Traffic Jam Assistant supports the driver with vehicle control in traffic jam situations. Steering support takes place without the driver actively steering.
• 5AU Active Driving Assistant Pro
Website: "Traffic Jam Assist; Steering and Lane Control Assistant; Emergency Stop Assistant to bring the vehicle to a stop in case of a health emergency; and Evasion Aid"
(see below,
TurtleBoy covered the emergency stop)
Driving Assistance Pro Package includes:
• ACC w/ Stop & Go,
As you know, active cruise control
• Active Lane Keeping Assistant w/ Side Collision Avoidance,
As
TurtleBoy said:
at speeds of up to 130 mph/210 km/h, the system can intervene with a brief active steering intervention and help guide the vehicle back into the lane.
• Steering & Traffic Jam Assistant,
In stop-n-go traffic < 40mph:
The system assists the driver in keeping the vehicle within the lane. For this purpose, the system executes supporting steering movements, for instance when driving in a curve. It works in coordination with ACC so you don't have to work much in heavy traffic with speed or steering.
• Automatic Lane Change,
With ACC, if you hold the turn indicator the vehicle will automatically change lanes for you
• Evasion Assistant & Cross-Traffic Alert Front
The system supports the driver in making evasive maneuvers in certain situations, such as when obstacles or persons suddenly appear. The system issues a warning and intervenes to support the driver if a lateral evasive maneuver is possible. Sensors monitor and detect the clearance around the vehicle. If the system identifies space alongside the vehicle, it supports an evasive maneuver begun by the driver by safely providing targeted steering support.
Standard Equipment:
✔︎ 5AL Active Protection
When a collision seems to be unavoidable, PreCrash functions are triggered
✔︎ 5AS Active Driving Assistant
My words, this is the catch-all for orchestration of those safety systems installed in the vehicle, aka "intelligent safety":
Intelligent Safety enables central operation of the driver assistance systems
✔︎ ZN1 Active Blind Spot Detection
Blind spot collision warning detects vehicles in the blind spot or vehicles approaching from be‐ hind in the adjacent lane ... The light in the exterior mirror lights up
✔︎ ZN3 Frontal Collision Warning w/ City Collision Mitigation
FCW:
The system may prevent some accidents. In the event of an accident, the system may reduce impact speed.
The system sounds a warning before an imminent collision and activates brakes independ‐ ently, if needed.
CCM:
The system may prevent some accidents with cross traffic at intersections and junctions. In the event of an accident, the system may reduce impact speed. The system sounds a warning in the city speed range before an imminent collision and activates brakes independently, if needed.
✔︎ ZN4 Lane Departure Warning
The lane departure warning alerts when the vehicle is about to run off the road or exit the lane.
To your point, the marketing wording is a bit funny but the features are more/less differentiated as above around things that automatically move the steering wheel ...
I'd say the summary is this:
If you want all of the safety systems that are actually capable of moving the vehicle via the steering wheel (to avoid accidents) then you'd want DAPP, which also comes with the added ACC features required with moving the steering wheel like lane changing and traffic jam assist.
