- This particular and optional exemplary embodiment makes it possible to reduce the quantity of data exchanged between the vehicle 10 and the “cloud” 100 by transmitting the request only when the confidence level is below a threshold. This particular and optional embodiment also makes it possible to guarantee that the regulatory speed displayed has a high level of confidence, that is to say greater than the set threshold.
