In this paper, a longitudinal and lateral control approach is proposed for a convoy of multi vehicles. A global decentralized architecture based on the information from neighbors and the leader vehicle is used, to ensure
stability and safety between neighbors. Lateral control based on the longitudinal speed of the i-th vehicle and the characteristic of the reference trajectory of the leader to cancel the lateral deviation of the convoy
from this trajectory and also allows coupled longitudinal and lateral motion control. The robustness of the linearization control by inverse dynamics (for longitudinal movement) and the sliding mode control (for
lateral movement), concerning the parameters of the dynamic model, will be studied in this paper. To compare different control approaches for the convoy, we add sensor errors between vehicles, to study the accumulation
of the errors towards the other cars of the convoy. To validate these approaches, we use the platform of SCANeRTM-Studio to control a convoy of 10 vehicles.
