BMW 3: PostCrash - iBrake
Concept
In the event of an accident, the system can bring the vehicle to a halt automatically without intervention by the driver in certain situations. This can reduce the risk of a further collision and the consequences thereof.
At standstill
After coming to a halt, the brake is released automatically.
Harder vehicle braking
In certain situations, it can be necessary to bring the vehicle to a halt more quickly than the Brake Assistant allows.
To do this, quickly apply extra force to the brake.
For a brief period, the braking pressure will be higher than the braking pressure that is achieved by the automatic braking function. Automatic braking is interrupted.
Interrupting automatic braking
It can be necessary to interrupt automatic braking in certain situations, for instance for an evasive maneuver.
Interrupt automatic braking:
- By pressing the brake pedal.
- By pressing the accelerator pedal.

General information
The system can detect decreasing alertness or
fatigue of the driver during long, monotonous
trips, for instance on highways. In this situation, it
is recommended that the driver ta

ABS prevents locking of the wheels during braking.
The vehicle maintains its steering power even
during full brake applications, thus increasing active
safety.

Introduction
The electrical machine in the G20 PHEV is a permanently excited synchronous
machine. It can convert
electrical energy from the high-voltage battery unit into kinetic energy, by
which the vehicle is driven.

Regenerative braking
The regenerative braking makes possible brake energy regeneration. The
electrical machine works
here as an alternator and brakes the gears via automatic transmission -
propeller shaft - rear axle
differential - output shafts. The high-voltage battery unit is charged with the
