Trajectory Tracking Control of Intelligent X-by-Wire Vehicles
Round 1
Reviewer 1 Report
The paper proposes some interesting ideas but some items must be clarified of improved:
- Contributions in section 1 are clear but it is not clear how these results improve other state of the art approaches.
- Figure 2 constraints do not follow exactly the friction ellipse concept. Please discuss.
- Results are based only on simulations. Can real tests be included? If not, discuss difficulties and the fact that simulations results are reliable enough

Reviewer 2 Report
This paper designed a trajectory tracking algorithm based on hierarchical structure for the control problem of trajectory tracking of x-by-wire electric vehicle. The effectiveness of the proposed control algorithm is verified based on simulation experiments. Here are some questions and suggestions that may help the authors to improve the paper.
1. Tire models are not considered in this article. Will it have an impact on control?
2. There is a typographical error in Equation 38.
3. The writing of the letter c in Equation 39 is inconsistent and its meaning should be stated.
4. Figure 2 is too simple to show the method of Equation 28, and the coordinates should be labeled.
5. The acquisition of vertical loads should be described.
6. It should be compared with other methods.
7. The tire sideslip angle is an important indicator of tire stability, which cannot be ignored. However, it is obviously unreasonable to ignore it in this paper. How to take the value of the parameter in Equation 39.
8. The graph of lateral velocity and acceleration is obviously problematic.
9. Why does the driving torque fluctuate so much in the first 5s of Figgure 5a?
