A system for analyzing a structure of a vehicle controller area network (CAN) is configured to obtain a level 2 (LV2) application software module, process the LV2 application software module to extract a set of LV2 variables from the LV2 application software module, obtain a plurality of lists of signals corresponding to a plurality of development teams of the vehicle, process the plurality of lists of signals to extract respective sets of LV2 signals from the plurality of lists of signals, generate a LV2 variable map based on the extracted set of LV2 variables and the extracted sets of LV2 signals, and generate a LV2 signal report detailing a set of inconsistencies based on an analysis of the generated LV2 variable map.

Systems and methods for monitoring and analyzing the structure of a vehicle controller area network

A control system for a mild hybrid vehicle is configured to detect whether a main contactor is open, the main contactor being connected between a primary battery system and a bi-directional direct current to direct current (DC-DC) converter and in response to detecting that the main contactor is open: command the DC-DC converter to operate in a boost mode to excite a motor-generator unit (MGU), after the excitation of the MGU has completed, command the DC-DC converter to operate in a buck mode, determine a previous voltage regulation feedback setpoint for the DC-DC converter, and control the DC-DC converter to maintain a voltage of the secondary battery system within a desired range by inserting a delay to a voltage control loop of the DC-DC converter such that the voltage control loop mimics a bandwidth of the MGU.
