Valve position control method, device, equipment, medium and automobile engine cooling system

Abstract

The invention discloses a valve position control method and device and an automobile engine cooling system. The method obtains the heat dissipation and heat generation of the whole vehicle; determines the correction transition time according to the heat dissipation and the heat generation; determines the The working mode of the temperature control device; determine the correction amount according to the working mode; obtain the current position information of the valve; calculate the target position information according to the current position information and the correction value; send the target position information to the temperature control device. control device, so that the temperature control device adjusts the position of the valve to the position corresponding to the target position information within the corrected transition period, so as to realize the temperature control of the coolant of the engine according to the current state of the vehicle. Level adjustment, so that the engine is in the best working condition.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a valve position control method, device, equipment, medium and an automobile engine cooling system. Background technique [0002] In order to cool down the engine of the car and make the engine work in the best working condition, the general engine will have a cooling system. At present, the vehicle cooling system on the market usually uses a mechanical water pump + thermostat to control the switch of the radiator branch. The physical structure of the thermostat is mainly based on the wax bag. When the operating temperature of the engine is low, the wax bag is solid, the spring is restricted, the branch of the coolant leading to the radiator is closed, and when the operating temperature of the engine is too high, the wax bag melts , the spring acts to open the radiator branch to cool down the engine. [0003] The thermostat usually does not have active control. As the temperature of ...

AI Technical Summary

Problems solved by technology

The emergence of the electronic thermostat has improved this situation. It adopts the form of an electric heating wax bag, which can actively control the opening and closing of the radiator, but in order to avoid the long-term work of the thermostat in the transient process due to slow response In some cases, the electronic thermostat generally only divides the engine operating conditions into several simple intervals in control, and when the operating temperature of the engine reaches a certain interval, it will make corresponding adjustments, and it cannot be very fine for each Optimizing a working state
