Flow valve control method and apparatus, and storage medium
A flow valve control method, apparatus, and storage medium are provided. The method comprises: conducting a median current value teach-in of a flow valve starting from an initial median current value of the flow valve; and correcting a flow-current curve of the flow valve based on a deviation value obtained by the teach-in. Each teach-in process comprises: controlling current output to a flow valve, so that the flow valve successively goes through: when there is a flow passing through, an output flow enables a shifting mechanism to return to position, and when there is a flow passing through again, an output flow again enables the shifting mechanism to return to position; recording a current value the twice when there is a flow passing through the flow valve as a maximum median current value; and acquiring a deviation value of the maximum median current value from the initial median current value.

Transmission Control System, Method, and Apparatus
An apparatus is disclosed. The apparatus has a first valve assembly that is actuatable between a first position and a second position, a transmission component fluidly connected to the first valve assembly, and a second valve assembly, which is actuatable between a first position and a second position, fluidly connected to the first valve assembly. The first valve assembly is disposed between the second valve assembly and the transmission component. The transmission component is locked when the first valve assembly is in its first position. The transmission component is unlocked when the first valve assembly is in its second position. A pressurized transmission fluid bypasses the second valve assembly when the second valve assembly is in either its first position or its second position.
