APF-DPPO: An Automatic Driving Policy Learning Method Based on the Artificial Potential Field Method to Optimize the Reward Function
Round 1
Reviewer 1 Report
The article proposes an end-to-end autonomous driving strategy learning method based on deep reinforcement learning, which can improve the autonomous decision-making efficiency of the vehicle.
The article is very interesting and well structured.
However, before publication, it requires a major update:
1) Improve the state of the art. For instance see ( [G. N. Bifulco, A. Coppola, S. G. Loizou, A. Petrillo and S. Santini, "Combined Energy-oriented Path Following and Collision Avoidance approach for Autonomous Electric Vehicles via Nonlinear Model Predictive Control," 2021 IEEE International Conference on Environment and Electrical Engineering and 2021 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2021, pp. 1-6], [Gao, K., Yan, D., Yang, F., Xie, J., Liu, L., Du, R., & Xiong, N. (2019). Conditional artificial potential field-based autonomous vehicle safety control with interference of lane changing in mixed traffic scenario. Sensors, 19(19), 4199.], [Z. Zhu and H. Zhao, "A Survey of Deep RL and IL for Autonomous Driving Policy Learning," in IEEE Transactions on Intelligent Transportation Systems, doi: 10.1109/TITS.2021.3134702.])
2) Tables are extremely large. Please, improve their quality.
3) It would be interesting to add another example test scenario with two (conflicting) vehicles
4) A comparison with other approaches should be added.

Reviewer 2 Report
Dear Authors:
Thanks for your efforts.
The paper proposes an end-to-end autonomous driving strategy learning method based on deep reinforcement learning, which can improve the autonomous decision-making efficiency of the vehicle.
Here are some questions listed as follows:
Q1: In Abstract and Conclusion, What are the numerical improvements based on the experiments?
Q2: Throughout context, there are some English words and senstances are not properly used, such as "rule based" not "rule base", etc.
Q3: In Equations (2, 3), what are the definitions of V(.) and Phi'?
Q4: In Equation (5), what is the definition of Et?
Q5: In Tbale 2, the ranges of speed control and steering angle are not meaningful. The ranges are based on normalization? Please specify.
Q6: In Page 10, the paragraph just above 3.4.2, "0the" is not meaningful. Please rectify.
Q7: Please review this Algorithm 1 in terms of format and English.
Q8: What are the numerical improvements of the approach proposed?
Q9: What are the limitations and drawbacks of this approach?
Thanks and Best Regards
