Rear zone module and rear zone controller
First Claim
1. A vehicle, comprising:
- a rear zone module (RZM) that includes at least a power liftgate (PLG) module, heated back window module, and a rear window wiper module;
a circuit in the rear zone module configured to mutually exclusively operate the PLG module from the heated back window module and the rear window wiper module, wherein current flows only in one of the PLG or in at least one of the heated back window and rear window wiper module; and
a controller configured to selectively control the current with respect to the circuit, wherein interconnections between the RZM and controller are minimized by sharing the interconnections.

Abstract
Described herein is a rear zone module and rear zone controller that minimizes wire gauge and current draw. The rear zone module shares outputs amongst several functions including rear windshield wiper, heated back window, power liftgate controller and the like. These outputs can be shared because not all functions are required to be active at the same time. For example, a vehicle includes a rear zone module (RZM) that includes at least a power liftgate (PLG) module, heated back window module, and a rear window wiper module. The vehicle also includes a controller configured to selectively control current with respect to at least the PLG module, heated back window module, and a rear window wiper module. The interconnections between the RZM and controller are minimized by sharing the interconnections as the PLG module operates mutually exclusively from the heated back window and rear window wiper module.

15. A circuit, comprising:
-
a rear zone circuit that includes at least a power liftgate (PLG) circuit, heated back window circuit, and a rear window wiper circuit, wherein the PLG circuit operates mutually exclusively from the heated back window circuit and rear window wiper circuit and wherein current flows only in one of the PLG or in at least one of the heated back window and rear window wiper module; and a control circuit configured to selectively control current with respect to at least the PLG circuit, heated back window circuit, and a rear window wiper circuit, wherein interconnections between the rear zone circuit and control circuit are minimized by sharing the interconnections. - View Dependent Claims (16)
