Info

It is the first year for Chalmers Formula Student Driverless and we present a reliable autonomous race car based on the 2017 electric car. The team consists of 15 second year master students: 7 members from last years electric team together with 8 new members with diversified background in both hardware and software engineering. The software platform for this car is a unique platform for Chalmers and all of the software used in the car is self-developed by the team during the past year.

DV System Highlights	Perception combines LiDAR and Camera using cone positions provided by the LiDAR to define Regions of Interest for a CNN. Steering is controlled by a velocity dependent aimpoint considering the number of cones seen and velocity is dependent on road curvature. The unique OpenDLV framework is used to realize the software as a suite of microservices.
