Abstract

The invention discloses a coolant filling control method and device. The control method comprises the steps that conductivity of a coolant to be filled into a cooling system of an engine is obtained;whether the conductivity is in a first preset conductivity range is determined, and if it is, an on-off valve connected to the cooling system is controlled to be open and the cooling system is filledwith the coolant; a current cumulative filling volume of the coolant filled to the cooling system and a current liquid level of the coolant in an expansion tank are obtained; and according to the current cumulative filling volume and the current liquid level, whether the on-off valve is controlled to close and stop filling the cooling system with coolant is determined. The method determines the quality of the coolant through the conductivity, and determines whether the amount of the coolant filled to the cooling system reaches a reasonable value through the current cumulative filling volume and the current liquid level, can ensure that the quality of the coolant filled into the cooling system is qualified and the filling amount is reasonable, so that the cooling system can achieve an expected cooling effect

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a cooling liquid filling control method and device. Background technique [0002] With the increasing number of automobiles, the performance and safety of automobile engines have become the key concerns of automobile manufacturers and consumers. [0003] Currently, in order to ensure the normal operation of the engine, it is necessary to add coolant to the cooling system of the engine. However, in the current process of adding coolant, the cooling system cannot achieve the cooling effect it should due to reasons such as filling the wrong coolant, coolant failure, and failure to degas in time, which reduces the performance of the engine. , and even cause damage to the engine. Contents of the invention [0004] In view of the above problems, the present invention provides a coolant filling control method and device that overcomes the above problems or at least partial...
