Distance control
General:
Brief description
The distance control is intended to avoid rear-end collisions of faster and slower vehicles.
Nevertheless, rear-end collisions with vehicles with nearly exhausted storage battery will not be avoidable.
Speeds of the vehicles
Note:
sec.
A
Standard adjustment – stop time
The electronic equipment for the stop point
If the faster vehicle catches up with the slower vehicle before this vehicle reaches the distance stop point, the stopping
time will have to be extended.
Recommendation: min. stopping time
Functioning:
B
Distance control
Considering traffic conditions, the stop point
The sliding magnet of the vehicle driving ahead will activate the electronic equipment via sensor
Stop point
M ..
will be active for time
A
red
light-emitting diode (LED) in the controller will light, if stop point
The length of the active time
If the car that follows reaches this stop point
the distance will thus be increased for the vehicle driving ahead.
with flat carriageway and charged storage battery:
Moving truck, semitrailer, tank truck and bus approx. 18 .. 21 cm / sec.
Moving passenger car, light-duty truck approx. 14 .. 17 cm / sec.
with the storage battery almost exhausted, the speed will be reduced further by approx. 3 cm /
The speeds of ascending vehicles must be calculated from case to case.
M ..
is set to a stop time
approx. 4 seconds to be expected between distance stop points per 1 metre of route
e.g.:
Route = 2 metres; this results in a
stopping time of = 8 seconds (2 x 4 seconds)
related to routes commonly used by passenger car and truck/bus.
