SUMMARY OF ILLUSTRATIVE VARIATIONS

Other illustrative variations within the scope of the invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while disclosing variations of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.



BRIEF DESCRIPTION OF THE DRAWINGS
Select examples of variations within the scope of the invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
FIG. 1 illustrates a number of sequential logic scenarios which a controller may to track and handle.



DETAILED DESCRIPTION OF ILLUSTRATIVE VARIATIONS
The following description of the variations is merely illustrative in nature and is in no way intended to limit the scope of the invention, its application, or uses.
In a number of illustrative variations, a vehicle may consume both electrical charge and fuel during the duration of operation. The vehicle may comprise a number of components including but not limited to doors, seatbelts, seats, etc. The vehicle may also include any number of sensors which may sense and be polled and/or read by a controller. Additionally, the sensors may sense and produce signals based upon the at least one of the engagement, orientation, state or condition of any number of components. Additionally, at least one of the sensor signals or readings may be used by a controller in sequential logic as well as combinational logic.
In a number of illustrative variations, a controller, which is capable of processing sequential logic as well as combinational logic, may be housed onboard a vehicle. Additionally, a device capable of reading data from memory and/or external storage devices may be in electrical communication with vehicle components including but not limited to the controller. The controller may have onboard memory and may be in electrical communication with an external data storage device as well as external memory devices. The controller may be in electrical communication with any number of sensors, controllers, batteries, renewable energy sources or other electrical devices and may have the ability to store and timestamp data indicative of readings and/or signals from any number of sensors.
In a number of illustrative variations, a first sensor may be used to detect that a first door is open; a second sensor may be used to detect that a second door is open; a third sensor may be used to detect whether a fuel and/or charge supplying device is connected to the vehicle; and a notification may be produced based upon sequential logic applied to at least one of sequential readings or sequential signals from the third sensor, and at least one of the first sensor or second sensor.
In a number of illustrative variations, a first sensor may be used to detect whether a fueling and/or charging door of the fuel and/or charge consuming device is open; a second sensor may be used to detect whether a driver's side door of the fuel and/or charge consuming device is open; a third sensor may be used to detect whether a fuel and/or charge supplying device is connected to the fuel and/or charge consuming device; and an alert may be produced based upon at least one of sequential readings or sequential signals from the third sensor, and at least one of the first sensor or second sensor.
In another illustrative variation, a sequential logic based notification system may be bound by a particular sequence. For example, a first sensor may be used to detect whether a fueling and/or charging door of the fuel and/or charge consuming device is open. Then, a third sensor may be used to detect that a fuel and/or charge supplying device is disconnected from the fuel and/or charge consuming device. Subsequently, a second sensor may be used to detect that a driver's side door of the fuel and/or charge consuming device is opened. Finally an alert may be raised based upon at least one of sequential readings or sequential signals from the first, second and third sensor.
In a number of illustrative variations, there may be several stages or states of sequential logic, each having a name. As shown in the non-limiting illustration of FIG. 1. In FIG. 1, there are 4 states, each denoting noteworthy progress in a sequence. A sequence for a number of illustrative variations can be found in FIG. 1 by noting that there is no direct transition from “Standby” to “Remind”. That is, in FIG. 1, a sequence of events must occur in order to trigger the production of a reminder, alert, notification, etc.
In a number of illustrative variations, sequential steps may be tracked by software using flags, interrupts, exception handling, signal handling or any other method known in the art or any combination of the aforementioned. For example, a first sensor may detect that a charge port door is closed and a controller may denote this by responding to at least one of a signal or reading from the first sensor by asserting a “STANDBY” flag variable in memory. Subsequently, a third sensor may detect that a fuel and/or charge supplying device is connect to the fuel and/or charge consuming device and the controller may denote this by responding to at least one of a signal or reading from the third sensor by asserting a “CONNECTED” flag variable, and deserting the “STANDBY” flag variable in memory. The third sensor may then detect that the fuel and/or charge supplying device is disconnected from the fuel and/or charge consuming device. The controller may denote this in memory by responding to at least one of a signal or reading from the third sensor by asserting a “READY” flag variable, and deserting the “CONNECTED” flag variable in memory. A second sensor may subsequently detect that a driver's door is opened and the controller may denote this by responding to at least one of a signal or reading from the second sensor by asserting a “REMIND” flag variable, and deserting the “CONNECTED” flag variable in memory. A memory reading device, which may perform a cyclic read on the “REMIND” flag variable in memory, may then read the “REMIND” flag variable and may, because the “REMIND” flag variable is asserted, and send a signal to the controller which may handle the signal by producing a notification or alert to a user after any amount of delay time.
In a number of illustrative variations, an alert may be produced by any number of sensory means including but not limited to an audio notification by a device such as a speaker, a visual notification by a device such as a display screen or an indicator light, or a physical notification such as a physical pop-out indicator or a vibrating component which may come into contact with the user. Means for producing such an alert may be located on the interior of the vehicle as well as on the exterior of the vehicle.
In a number of illustrative variations, an alert may be produced by a first source, located outside of the vehicle cabin, and further conveyed to the user through a secondary source, within the cabin of the vehicle. For example, a beep may be produced by a speaker under the hood of the car and a reminder may also be displayed as a backlit icon within the interior of the car. Further, the secondary source may require some additional step to occur before it will produce an alert. For example, the backlit icon within the interior of the car may not light up until the car is taken out of park. This additional step may also be tracked as sequential logic by the controller.
