Valve position control method and 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 comprises the steps of acquiring the heat dissipating capacity and a heating value of a finished automobile; determining the correction transition duration according to the heat dissipating capacity and the heating value; determining a working mode of a temperature control device; determining a correction amount according to the working mode; acquiring current position information of a valve; calculating target position information according to the current position information and the correction amount; and sending the target position information to the temperature control device, and enabling the temperature control device to adjust the position of the valve to a position corresponding to the target position information within the correction transition duration, so that the temperature of a cooling fluid of an engine is steplessly adjusted according to a current state of an automobile, and an engine is ensured to be at an optimal working state.

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 ...

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
