The disclosure provides a fuel saving robot system of mixed hybrid heavy duty trucks mainly for long haul logistics on highways. According to the vehicle-mounted 3D electronic map, the dynamic 3D positioning data of the vehicle measured by the GNSS, parameters of vehicle subsystems and the state of charge of the power battery pack, and data such as relative speed and absolute distance between the vehicle and the vehicle ahead in the same lane measured by the forward looking millimeter wave radar, the electrical power split device is commanded by the vehicle control unit through dynamic collaboration between the cloud AI brain and the vehicle-mounted AI brain of the fuel saving robot to allocate the flow direction and amplitude of 100 kW-class electric power accurately and dynamically among the internal combustion engine, generator, battery pack and driving motor with response time of 10 ms level, meet the transient power balance required by the vehicle dynamics equation in real time, and achieve the beneficial effects of minimization of vehicle fuel consumption and emissions, reduction of drivers' labor intensity of long-distance driving, improvement of active safety of vehicle running and the like through the fuel saving control algorithm of predictive adaptive cruise.
