Abstract

The invention relates to a vehicle cooperative energy management method and system under the DCPS framework. Under the distributed CPS architecture, the vehicle collaborative energy management method uses the pseudo-spectral method to plan the target mileage according to the obtained control-oriented model in the distance domain. After determining the optimal reference speed, the control-oriented The model constructs the explicit control rate model, and then adopts the explicit control rate model to determine the optimal control amount with the optimal reference vehicle speed, current vehicle speed and initial vehicle speed as input, and finally accurately manage the energy of the vehicle in real time and effectively according to the optimal control amount.

Description

technical field [0001] The present invention relates to the field of vehicle control, in particular to a vehicle cooperative energy management method and system under the DCPS framework. Background technique [0002] The state planning module of the existing energy management technology and its embedded model usually provide state reference based on the time domain. However, in practical applications, the vehicle will inevitably be disturbed by external unknown factors at certain moments, so that the actual operating state of the vehicle is different from the planned state. There is a deviation. This deviation will cause the state reference originally planned by the vehicle after the deviation time to not conform to the actual application scenario, and re-planning is required. This repeated planning will inevitably lead to a large waste of computing resources on-board or cloud devices. In view of the above problems, this scheme designs a control-oriented model construction m...
