Never look at the laser sensor through
an optical instrument (magnifying glass,
microscope...) at a distance of less than
10 centimetres: risk of eye injury.
Active City Brake
Principle
A preventive driving assistance system that, using
a sensor located at the top of the windscreen,
automatically applies the vehicle's brakes if behind
a vehicle in the same lane that is slowing down
rapidly, stopping or is stationary.
The objective is to avoid a collision or reduce the
speed of impact.
The Active City Brake system can in no circumstances
replace the need for vigilance on the part of the driver.
Operation
Required conditions:
- Vehicles driving in the same lane.
- Not in too pronounced a bend.
- Speed of the vehicle between 3 and
18 mph (5 and 30 km).
- Braking assistance systems (ABS, EBFD,
EBA) in working order.
- Trajectory control systems (ASR, DSC) in
working order and not deactivated.
- Operation of Active City Brake not
triggered in the previous 10 seconds.
During detection:
-
Display of a message.
- Illumination of the brake lamps.
The automatic braking occurs later than when
normal by the driver and only takes place if
the driver fails to apply the brakes at all or
sufficiently firmly, or to take avoiding action.
