Engine heat management controller and online strategy configuration method

Abstract

The invention relates to an engine heat management controller and an online strategy configuration method. The engine heat management controller consists of a CPU (Central Processing unit), a non-volatile storage system, a communication system, an information acquisition system and a control output system, wherein the CPU unit is connected with the non-volatile storage system, the communication system, the information acquisition system and the control output system respectively. Through the online configuration function of the engine heat management controller, a complete circulation and iteration process ranging from strategy configuration, strategy resolving and effectiveness, control result monitoring and reconfiguration after the completion of strategy modification can be constructed, a final optical heat management strategy can be found very conveniently, and an optical effect of the heat management system is developed.

Description

technical field [0001] The invention belongs to the field of thermal management systems or cooling systems for power components such as engines or power battery packs, and in particular relates to an engine thermal management controller and a strategy online configuration method. Background technique [0002] The engine thermal management system or cooling system is mainly composed of thermal management modules such as water radiators, intercoolers, and cooling fans, and controllers. The controller is the core of the system. It can monitor the controlled parameters such as engine temperature in real time. The internal preset control strategies and rules control the speed of the fan and the cooling intensity of the cooling system, etc., so that the controlled parameters are kept within the optimal range, thereby ensuring the safety of the application of the engine system, and having energy saving, emission reduction, Noise reduction function. [0003] However, the control st...

AI Technical Summary

Problems solved by technology

[0003] However, the control strategy of the current engine thermal management controller is relatively simple, and it has been solidified and hard-coded when the controller is produced, and the end customers such as automobile factories have various models, and the application environment, engine and other power component parameters 1. The layout conditions of thermal management systems are not the same, so the optimal thermal management control strategies required are also different.

Therefore, the controller cannot be configured online to change the thermal management strategy and monitor the thermal management control effect. would not apply at all
