Abstract
Exemplary embodiments are directed to systems and methods for tracking data during operation of a power transfer device. A system may include an electrical relay and a switch. The switch may be coupled to each of the electrical relay and a power transfer device and may be configured to couple the electrical relay to a reference voltage upon engagement of the power transfer device. The system may further include a processing unit configured to receive a signal from the electrical relay while the power transfer device is engaged.
Claims22
A system, comprising:
- a power transfer device;
- a switch coupled to each of an electrical relay and a reference voltage and configured to couple the electrical relay to the reference voltage upon engagement of the power transfer device;
- a valve configured to independently engage the power transfer device and enable the switch;
- and
- a processing unit configured to receive a signal from the electrical relay while the power transfer device is engaged.
2 more elements
A method, comprising:
- engaging a power transfer device with a valve;
- enabling a switch with the valve independent of the power transfer device;
- coupling an electrical relay to a ground voltage via the switch to generate an electrical signal upon a power transfer device being enabled;
- conveying the electrical signal from the electrical relay to a processor while the power transfer device is enabled;
- and
- electrically isolating the electrical relay from the ground voltage via the switch upon the power transfer device being disabled.
3 more elements
A method, comprising:
- enabling a switch in response to pressure from a valve;
- activating a power transfer device independent of the switch and in response to pressure from the valve;
- and
- generating an electrical signal in response to the enabled switch to track data while the power transfer device is activated.
1 more element
A system, comprising:
- an engine;
- a power transfer device coupled to the engine;
- a valve independently coupled to each of the power transfer device and a switch and configured to engage the power transfer device and independently enable the switch to generate a signal indicative of the engagement of the power transfer device;
- and
- a processing unit coupled to the engine and configured to determine an amount of fuel used by the engine during engagement of the power transfer device.
