The invention provides a heat management control system for an automobile engine. The system comprises a cooling device and a control device. The cooling device comprises a cooling pipe, a liquid feeding pump and a heat dissipator. The control device comprises a driving control part and a feedback control part. The driving control part comprises a master control end storage unit, a master controlend information acquisition module, a master control end index unit, a master control end computing unit, a master control end judging unit, a master control end control unit and a driving module. Thedriving module is provided with a water pump driving unit. The feedback control part comprises a feedback end storage unit, a feedback end information acquisition module, a feedback end judging unitand a feedback end control unit. The feedback end information acquisition module is provided with an outflux temperature sensor for acquiring the temperature of a cooling liquid at an outflux in realtime, the master control end control unit controls the water pump driving unit to operate the liquid feeding pump at a corresponding flow according to a beyond temperature difference, and the feedbackend control unit increases the flow of the liquid feeding pump at a preset proportion according to a preset duration.
Description
technical field [0001] The invention belongs to the field of engines, and in particular relates to a thermal management control system of an automobile engine. Background technique [0002] Automotive engine thermal management technology is one of the key technologies to ensure the normal operation of vehicles, and has great potential for improving vehicle performance. With the development of computer technology and engine electronic control technology, electronically driven and controlled cooling water pumps, fans, thermostats and other components can be controlled and operated according to the actual engine temperature through sensors and computer chips to realize intelligent control of the engine cooling system , reducing energy consumption and improving efficiency. [0003] The current engine thermal management control method is mainly based on a single feedback control method, that is, the ECU (vehicle computer, the same below) operates the water pump and fan according...
