Design Optimization of In-Vehicle Network

In this thesis, to tackle such a challenge, we propose a suite of design optimization methods for modern in-vehicle network architectures. First, we present PAMT, an optimal priority assignment algorithm for a single mixed CAN and CAN-FD bus. By clustering messages based on their type, PAMT minimizes negative impacts of the timing overhead for mode transitions. Second, we propose EACAN to relax the pessimistic assumptions used in the formal verification for CAN communication. Third, we identify configurable parameters for standardized frame preemption of Ethernet Time-Sensitive Networking (TSN) and present DOFP, a genetic algorithm based optimization framework for the frame preemption. Fourth, we propose bf OPMB, an optimal priority assignment algorithm for multi CAN/CAN-FD buses with a central gateway. Finally, we propose PRMB which finds a schedulable priority assignment and generates routing tables to use signal-based routing at the central gateway while meeting the timing requirements of in-vehicle data.
