Info
The DHBW Engineering builds electric vehicles since 2009. After a two-year development period, we introduce our first driverless vehicle. We modified our electric vehicle form 2019 with all necessary DV components including two cameras and a LiDAR sensor and integrated our autonomous system into the vehicle. Nine bachelor students of the fields Computer Science and Mechatronics worked on the development of our autonomous software, another six members on the electrical and mechanical DV hardware.
Engineering Design Priorities:
Robust Autonomous System
Hardware Development
