Abstract: A vehicle communication network includes electronic control units arranged in a plurality of groups. The electronic control units pertaining to the same group are coupled to each other via a respective dedicated communication bus. A central controller is coupled to the plurality of local controllers. Electrical loads are coupled to one of the electronic control units. Each of the electronic control units is configured to decode the received CAN frame to produce the actuation signal for a respective electrical load in response to a CAN frame being received from the respective local controller and transmit a CAN wake-up frame to the respective local controller and encode the feedback signal into a CAN frame for transmission to the respective local controller in response to the feedback signal being received from the respective electrical load.

Abstract: A thermal control process for an electronic power device including a multi junction integrated circuit may include defining a first and at least one second groups of junctions, with each group including one first and at least one second junctions, and associating a thermal detector with each group. A first group control may be executed which detects group electric signals representative of the temperature detected by the thermal detectors, processes the group electric signals with reference to a group critical thermal event, identifies a critical group when the corresponding group electric signal detects the critical group thermal event, and generates group deactivating signals suitable for selectively deactivating the first and the at least one second junctions of the identified critical group with respect to the remaining junctions of the integrated circuit.
