Driverless
Following the trend in the automotive industry, an autonomous competition class was launched in 2017.
The vehicles are to drive completely autonomously around the race track.
In order to meet the new challenge, we participated directly in the first year of the competition with our first autonomous vehicle.

eace06.d
Technical innovations
- Sensor technology
For this innovative vehicle, 2 LIDAR sensors have been used for the first time. - Actuators
In the course of optimization, the vehicle changed from hydraulic to pneumatic brake actuation compared to its predecessor. - Software
The localization mapping was significantly revised
Sensors
- Two stereo cameras
- CarPC with high-end graphics card
- Computer Vision: Neural network for cone recognition
- ROS - Robot Operating System
- Inertial Measurement Unit for motion measurement
- Autonomous steering
- Autonomous hydraulic braking system
Actuation
- The pneumatic brake actuation acts with a force of up to 1200N
- A 24Nm servo motor with a planetary gear sets the steering angles</div
Software
- Acceleration and gyroscope data can be used to determine the position of the vehicle in real time
- An optional use of a GPS signal can additionally serve as a correction
- Compared to the predecessor, a much better track measurement and recognition of pylon positions has been implemented

eace04.d
Technical innovations
- Cameras
For object recognition, the eace04.d uses two stereo cameras - Neural network
A self-trained neural network recognizes the cones by itself - Steering actuator
A steering motor engages directly in the lower steering to maneuver the eace04.d around the track
