Abstract

The invention discloses a partitioned heat management control system suitable for an extended-range hybrid vehicle model, and belongs to the technical field of hybrid vehicles. A pure electric mode heat management loop is not influenced by an engine loop in an extended-range mode; the pure electric mode heat management loop comprises a passenger compartment front-row refrigerating / heating loop, a passenger compartment rear-row refrigerating / heating loop and a battery refrigerating / heating loop in a pure electric mode, and partition control of a passenger compartment heat management loop and battery control are achieved. The range extending mode heat management loop comprises an engine warming loop in the range extending mode, a passenger compartment front row refrigerating / heating loop, a passenger compartment rear row refrigerating / heating loop and a battery refrigerating / heating loop and is used for controlling heat distribution of engine heat generated in the passenger compartment front row, the passenger compartment rear row and the battery loop, and full utilization of engine waste heat is achieved. A circulation loop of the thermal management system can be reasonably and effectively controlled according to actual working condition requirements, the actual operation performance of the thermal management system is effectively improved, and the multiple purposes of energy conservation, comfort and cost reduction are achieved.

Description

Technical field [0001] The present invention belongs to the technical field of hybrid vehicle, and more particularly to a partition thermal management control system suitable for use in a row mixing model. Background technique [0002] At present, with energy utilization and environmental requirements, pure electric vehicles are trends and directions of transportation development, and pure electric vehicles' technical bottlenecks are charging and mileage concerns facing users. Hybrid Motors are a very advantageous new energy vehicle that solves an anxiety of electric vehicles user anxiety. The core of its thermal management technology: It is one of the most potential research directions of energy utilization of mixing vehicles through the battery and the engine. [0003] At the existing hybrid automotive engine, 60% to 70% of the heat is lost through the internal circulation system, and it cannot be fully utilized. Therefore, how to use this part of the waste heat energy is reaso...
