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.
