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

 + S

AnS

 + S

Br

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

For more information on the response time T

S

 of the LiDAR sensor, 

see "Technical data",

page 49

.

T

S

 = Response time of the LiDAR sensor

V

Maximum speed of the vehicle, from the relevant vehicle documentation

The response time T

S

 of the LiDAR sensor depends on:

the base response time of the LiDAR sensor

whether multiple sampling is set

Filter settings (e.g., particle filter)

ZR supplement

This supplement must be determined on an application-specific basis and taken into
account appropriately. The following factors can make it necessary to use a supple‐
ment: reflectors or shiny objects on the scan plane, multi-echo analysis, blanking size,
device filter (e.g., particle filter).
