Problems solved by technology

From the perspective of the solution method, the current mainstream solution method is the space domain solution, followed by the time domain, and the space-time domain is the least. Both the space domain and the time domain are systematically organized to use different speed constraints to give the solution method. method is still relatively small

Embodiment Construction

[0086] see Figure 1 to Figure 6 , an intelligent network-connected plug-in hybrid vehicle collaborative optimization energy management method, mainly includes the following steps:

[0087] 1) The intelligent network-connected plug-in hybrid electric vehicle obtains the speed limit condition in the time domain and the speed limit condition in the space domain from the intelligent transportation system through on-board GPS or radar. The speed limit condition is the maximum speed obtained through the intelligent transportation system with the minimum value.

[0088] 2), according to the control variables and state variables of the time-domain speed limit conditions and the space-domain speed limit conditions in step 1), and the limit conditions for establishing the collaborative optimization energy management method, use dynamic programming to establish the goal of the collaborative optimization energy management method function, which solves the optimality of the objective fun...

Abstract

Disclosed is an intelligent connected plug-in hybrid electric vehicle cooperative optimization energy management method. The method comprises the following steps that 1) an intelligent connected plug-in hybrid electric vehicle acquires speed limit conditions of a time domain and a space domain through an intelligent transportation system; 2) an objective function is established by utilizing dynamic programming according to the control variables and state variables of the speed limit conditions of the time domain and the space domain in the step 1) and the limit conditions of the cooperative optimization energy management method; 3) vehicle terminal state constraint is realized by using a travel distance adjusting factor in the time domain and a travel time adjusting factor in the space domain according to the objective function in the step 2); 4) intelligent connected plug-in hybrid electric vehicle cooperative optimization energy management is carried out by dynamic programming by combining the speed limit conditions in the step 1), the control variables, the state variables and the objective function in the step 2) and the vehicle terminal state constraint in the step 3); and 5)cooperative optimization energy management method in the step 4) is simplified.

Description

technical field [0001] The invention relates to the field of intelligent networked vehicles, in particular to a collaborative optimization energy management method for an intelligent networked plug-in hybrid electric vehicle. Background technique [0002] Electrification of vehicles is a means to solve the global energy crisis and environmental pollution, and this approach has attracted widespread attention in academia and industry. However, as we all know, the efficiency of the new energy vehicle transmission system and the performance optimization of the power source have encountered bottlenecks. With the gradual rise of the Internet of Everything and the wave of intelligence, the intelligent networking of automobiles will play a strong role in boosting the optimization of energy consumption and emission performance of new energy vehicles. Compared with pure electric vehicles (EV), plug-in hybrid electric vehicles (PHEV) have a longer driving range and lower dependence on...
