Modularized power take-off systems for vehicles
First Claim
1. A motor vehicle comprising:
- a vehicle system power source;
a controller area network;
a modular power unit coupled to the controller area network to receive control signals, the modular power unit comprising signal decoding means for generating switching signals in response to the control signals and power application switches responsive to the switching signals for controlling selective translation of power from the vehicle system power source to a load;
at least a first vocational controller coupled to the controller area network for communication; and
a modular power take off manager having an operator interface and being coupled to the vocational controller for transmitting control signals for the modular power unit over the controller area network.

Abstract
A vehicle power take off system provides power for a variety of systems including a source of alternating current power for conventional electrical equipment to be powered by the vehicle. In a preferred electrical implementation, the power take off system is energized from the vehicle direct current electrical power system and generates alternating current of the desired voltage using a derectifier and step up transformer. Management of the system is implemented through modularized units which may be connected to communicate with another over a vehicle'"'"'s controller area network. Load management may be monitored by an existing on board computer.
