Validation and testing are the

constant companions of every

development activity at AVL. Us-

ing simulation models for the de-

velopment of control functions

and virtual calibration ensures

greater efficiency. “This method-

ology can be applied at all levels,

from the software components

to system level,” says Louarn-

Pioch. Ultimately, everyone on the

ADAS/AD engineering team is

working toward a goal: To make

driving safer and more comfortable.

As more cameras, LiDARS or radars in the vehicle deliver a continuous

stream of data about the environment to the vehicle interior, software is

crucial for processing and interpreting all this information. Therefore,

Dominique Louarn-Pioch and Mathias Scheytt, department managers for

ADAS/AD at AVL Software and Functions, are avidly working togeth-

er with their teams of software engineers in Regensburg on the heartbeat

of future mobility.

“Proper interpretation requires specific know-how,” explains Louarn-

Pioch. Machine learning and image processing skills are becoming increas-

ingly important. In addition, of course, reliability and compliance with in-

ternational standards are mandatory from the first line of code. “We fully

understand the entire process chain,” adds Scheytt, referring to AVL’s vast

experience in the testing and software sector.

The modular software and control architecture enables the reuse of

tailored software and its integration from different suppliers (see picture).

After the detection of the environment (“perception”), the next important

steps are maneuver planning and decision making. Then longitudinal or

lateral controllers come into play: The longitudinal controller is respon-

sible for controlling the vehicle’s speed, while the lateral controller steers

the vehicle’s wheels for trajectory tracking. This gives actuators, such
