Solution Approach 2:

A cloud platform serves as an intermediary between vehicles and the energy recovery control system. The cloud platform receives historical deceleration data from multiple vehicles, performs centralized analysis to determine optimal target deceleration values, and transmits control instructions back to individual vehicles. This intermediary approach distributes system complexity from individual vehicles to the cloud infrastructure.
