Automotive Technology Overview

ADAS Technology Overview

For short range detection,

ultrasonic sensors could be

used (e.g. parking distance).

A complete view of the

environment can be

achieved using cameras.

Radars can be used for

long- and short range views.

Insensitive to light changes.

Range Data Processing

For long range

detection, Lidar sensors

could be used.
