Abstract
An expedited start-up procedure of an electrified vehicle involves a hybrid control processor (HCP) connected to a controller area network (CAN) having electrified powertrain (ePT) modules and an auxiliary HCP (AHCP) connected to the CAN and connected to the HCP via a hardwire wakeup line. In response to a start-up request, the HCP initializes the start-up procedure in which it sends a wakeup signal to the AHCP via the hardwire wakeup line, performs shutoff path testing via a first CAN bus, and confirms enabled ePT modules communication via a second CAN bus to complete the start-up procedure. In response to the wakeup signal from the HCP, the AHCP initializes and then participates in the start-up procedure in which it wakes up and enables communication by the plurality of ePT modules via the second CAN bus. A duration of the start-up procedure is less than a customer annoyance threshold.
