Embodiment Construction

[0014] Controller Area Network (CAN) is a high-speed communication bus that carries messages between Electronic Control Units (ECUs) in an automobile. ECUs typically send signals to the devices they control via a local interconnect network (LIN). LIN is a low-cost, low-speed communication bus commonly used between an ECU and the device it monitors or controls.

[0015] figure 1 An automobile 100 is shown having a radiator 102 , an engine 104 , and a transmission 106 . An engine control unit 108 may electronically control devices in the engine 104 and a transmission control unit (TCU) 110 may electronically control devices in the transmission 106 . Engine control unit 108 , TCU 110 and other vehicle systems may be connected to wiring harness 112 . In an embodiment of the invention, the automobile 100 has a coolant line running between the radiator 102 and the transmission 106, which can be used to regulate the temperature of the transmission. The TCU 110 may monitor the tem...

Abstract

A solenoid fluid control valve is disclosed for controlling fluid flow. The solenoid fluid control valve may comprise a transceiver that receives a signal via a controller area network (CAN) bus, and a micro controller unit that decodes the signal to determine a temperature. The micro controller unit may send a signal to a driver circuit based on the temperature. The driver circuit may send a current through a coil in response to the signal, wherein an armature moves in response to the current through the coil. The movement of the armature may direct a cooling fluid flow.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Nonprovisional Application Serial No. 14 / 222,132 filed March 21, 2014, the contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an electromagnetic fluid control valve for regulating the temperature of transmission fluid. Background technique [0004] Fluid control valves may be used to regulate the temperature of automotive equipment such as the engine or transmission. Above a certain threshold, the lubricating oil in the equipment can start to burn, reducing the efficiency of the equipment. Fluid control valves can be used to direct equipment-specific coolant through the radiator, thereby reducing the temperature of the equipment. [0005] The fluid control valve may be a mechanical valve that does not require electrical control signaling. Alternatively, the fluid control valve may be controlled by an electronic c...
