Messaging in a controller area network is modified to hide thermal engine torque and angular velocity change requests originating with selected nodes with relatively low contention access priority from an engine controller and to route the messages instead through an intermediary controller which is an independent source of thermal engine torque and angular velocity change requests. More specifically, in a hybrid vehicle having a body controller with operational control over power take off equipment, a hybrid controller and a thermal engine controller, angular velocity and torque change requests to support power take off operation are embedded in auxiliary input/output messages. The hybrid controller operates on these auxiliary messages, conflating the embedded angular velocity and torque change requests with its own and rebroadcast in conventional form. |
