Problems solved by technology

However, in China, the United States, and the European Union, the three largest and most technologically advanced long-distance freight heavy truck markets in the world, industry experts at home and abroad agree that before 2030, pure electric heavy trucks or hybrid heavy trucks cannot be used without subsidies. Realize large-scale commercial use

Abstract

Embodiments of the present disclosure provide a hybrid vehicle predictive power control system. The system is mainly aimed at long-distance freight heavy truck application scenarios; Based on the vehicle configuration parameters and the current operating conditions, with the aid of electronic navigation 3D map of vehicle expressway, the system can accurately and real-timely predict the dynamic road load power time-space function within the range of tens of kilometers of the electronic horizon in front of the vehicle, the electric power shunt is commanded by the vehicle controller, the direction and amplitude of the flow of the 100 kilowatt-level electric power are accurately and continuously adjusted among engine-driven generator set capable of being driven in tens of millisecond system response time, the battery pack and the drive motor;, keeping the engine working stably in its high efficiency area for a long time, the transient power balance of road load required by vehicle dynamicsequation can be satisfied in real time by fast charging and discharging of battery pack of several hundred kilowatts, Compared with traditional diesel heavy trucks, hybrid heavy trucks can greatly reduce the overall fuel consumption and emissions in real world operation under the premise of ensuring vehicle power, freight timeliness and driving safety.

Description

technical field [0001] The present invention relates to a predictive power control device and method for a hybrid vehicle, in particular to a predictive vehicle power control based on artificial intelligence for long-distance freight heavy trucks under normal loads and application scenarios mainly driving on highways, so as to realize adaptive cruise and achieve The beneficial effect of minimizing comprehensive fuel consumption and emission in vehicle operation. Background technique [0002] Today's European and American mandatory emission regulations for large commercial vehicles including heavy-duty trucks (referred to as "heavy trucks" with a gross vehicle weight greater than 15 tons) have changed from the Euro VI standard (fully implemented in Europe in 2014) and the US EPA2010 focusing on pollutant exhaust emissions. (fully implemented in the United States in 2010) to focus on carbon dioxide CO 2 Regulations based on greenhouse gas carbon emissions. The carbon emissio...
