ZR
= Supplement for application-related influences or the selected application parame‐
ters
ZB
= Supplement for the decreasing braking force of the vehicle. This can be obtained
from the relevant vehicle documentation, or alternatively: 10% of the stopping distance.
Stopping distance SA
The stopping distance comprises the vehicle’s braking distance and the distance cov‐
ered during the response time of the LiDAR sensor and the vehicle control’s response
time.

NOTE
Please note that a vehicle’s braking distance does not increase linearly with increasing
speed, but rather in a squared relationship. This is particularly important if you switch
between different-sized switching fields depending on the speed.
How to calculate the stopping distance SA:
SA = S

AnF
= The distance covered during the vehicle control’s response time, which is speci‐
fied in the vehicle documentation
S
AnS
= The distance covered during the response time of the LiDAR sensor
S
Br
= The braking distance, found in the vehicle documentation
The distance S
AnS
covered during the response time of the LiDAR sensor depends on:
•
the response time of the LiDAR sensor
•
the maximum speed of the vehicle in your mobile application
