| ABSTRACT |
|
Autonomous driving approaches today are mainly based on perception-planning-action modular pipelines and
the End2End paradigm respectively. The End2End paradigm is a strategy that directly maps raw sensor data to vehicle control
actions. This strategy is very promising and appealing because complex module design and cumbersome data labeling are
avoided. Since this approach lacks a degree of interpretability, safety and practicability. we propose an autonomous driving
approach based on trajectory learning using deep neural networks in this paper. In comparison to End2End algorithm, it is
found that the trajectory learning algorithm performs better in autonomous driving. As for trajectory learning algorithm, the
CNN_Raw-RNN network structure is established, which is verified to be more effective than the original CNN_LSTM network
structure. Besides, we propose an autonomous driving architecture of a pilot and copilot combination. The pilot is responsible
for trajectory prediction via imitation learning with labeled driving trajectories, while the copilot is a safety module that is
employed to verify the effectiveness of the vehicle trajectory by the results of the semantic segmentation auxiliary task. The
proposed autonomous driving architecture is verified with a real car on urban roads without manual intervention within 40 km. |
