Debt-Surplus Gauge

The debt-surplus gauge is a virtual gauge that displays the distance to the next charge point as it relates to the total distance to empty. The charge point needs to be set by the driver through the message center menu and controls. A surplus, or positive value, indicates the battery has sufficient charge to reach the charge point. A debt, or negative value, indicates the vehicle may not reach the next charge point. The debt-surplus gauge can be displayed in the budget view, the range view, the surplus view, the trip view and in my view. In addition, the debt-surplus gauge can be selected to display in the RH display screen. Each view slightly alters the way the gauge is displayed but the functionality is the same.

If the driver does not enter a charge point, the IPC displays Status in place of Surplus and Budget instead of Charge Point in the gauge display. In this case, a positive value represents an extended drive time before the battery is depleted. A negative value represents a shorter drive time before the battery is depleted.

The IPC receives the vehicle range, the vehicle efficiency data and the battery state of charge data from the GWM over the Infotainment Controller Area Network (I-CAN). The GWM receives the vehicle range and the vehicle efficiency data from the PCM and the battery state of charge data from the BECM over the Electric Vehicle (EV) High Speed Controller Area Network (HS-CAN).

The IPC receives the odometer count data from the GWM over the Medium Speed Controller Area Network (MS-CAN). The PCM receives the odometer count data from the ABS module over the Electric Vehicle (EV) High Speed Controller Area Network (HS-CAN).

The IPC also receives the charge point data from the APIM and the navigation destination data from the FCDIM over the Infotainment Controller Area Network (I-CAN).
