Towards Autonomous Driving: Review and Perspectives on Configuration and Control of Four-Wheel Independent Drive/Steering Electric Vehicles
Round 1
Reviewer 1 Report
This manuscript presents a review about configuration and control of four-wheel independent drive/steering electric vehicles. This manuscript contains control models, strategies, and algorithms of 4WID-4WIS EV. In addition, this review considers challenges and perspectives for 4WIND-4WIS EV. However, this manuscript must be significantly improved based on the following comments:
1.-English style and grammar of all the sections of manuscript must be improved.
2.-Introduction section. This section is very short. It should add more information of the importance, history, challenges, and investigations of autonomous vehicles.
3.-English style of second section should be improved.
4.-Quality of Figure 6 must be improved.
5.-Authors should include more discussion about the control framework of 4WIND-4WIRS EV shown in Figure 8.
6.-Authors must include more information of advantages and limitations of the references of third and fourth sections. These sections contain many references, which require more detail information. A review must add critical discussion about the investigations reported in the literature. In addition , these sections must include more figures and schematic views.
7.-Section of challenges and perspectives is poor. This section must contain more information and discussion about the limitations, challenges, and perspectives for 4WIND-4WIS EV.
8.-Section of conclusion must be improved considering the modifications or the revised manuscript.

Reviewer 2 Report
The article presents a very detailed and well done review on four wheel indipendant drive/steering electric vehicles.
Those vehicles are particularly interesting in the field of urban transport.
The article includes an overview of existing systems, the different suspension architectures, the applications (simulation, hil, test) and also provides the basic models including different degrees of freedom.
As it is a review article the originality of the work it the sound and profound analysis of existing work.
The review article adds a very valuable reference document in the domain.
Due to the clearness of the work, it is a document that I would suggest as first document to read for all people working in the domain.
Therefore, I would predice a huge number of citations for the proposed article.
The clearness of the review as well as the well developped and explained model is a reference for all futur works.
Researchers are not required to develop the model for analysis, they can start on the base of the model (and its variations) provided in the article and adapt it to a specific case.
Therefore, this study will allow considerable progress in the domain of autonomous four wheel drive electric vehicles, that are not yet studied in detail due to multiple degrees of freedom and associated risk of loss of control.
The conclusions are clear and encourage researchers do contribute to the domain and I am looking forward to see the kind of contributions that the same authors can propose in the future.
145 recent references from reknown sources are in coherence with the scope of the article.
The figures and tables are clear and well designed.
I hope my additional remarks contribute to the reviewing process.
