Abstract:
1. A modular power takeoff system comprising: a controller area network; an hydraulic pump; an hydraulic valve array connected to receive hydraulic fluid under pressure from the hydraulic pump; a valve controller connected to receive and transmit data over the controller area network and further connected to the hydraulic valve array for controlling the positioning of valves; at least a first hydraulic actuator connected to receive and return hydraulic fluid to the hydraulic valve array; an hydraulic fluid reservoir for collecting hydraulic fluid from the hydraulic valve array and providing hydraulic fluid to the hydraulic pump completing an hydraulic circuit; a plurality of sensors for generating operational data relating to the hydraulic circuit to the valve controller, the valve controller being adapted to provide for formatting of the data for transmission over the controller area network; an auxiliary gauge and switch package controller connected for communication over the controller area network for providing requests for control signals; and an operator interface connected to the auxiliary gauge and switch package for allowing operator inputs for generating requests for control signals an electrical system controller connected to the controller area network for data communication and further connected for receiving data relating to vehicle transmission status and vehicle parking brake status; and a program resident on the electrical system controller responsive upon execution to receipt of the operational data, vehicle transmission status, vehicle parking brake status and requests for signals for generating control signals for transmission over the controller area network.
