Abstract
GPF system is expected as a solution for PN/PM regulation which is becoming stricter in gasoline engines. The management system of GPF temperature and residual soot amount in GPF is necessary for the GPF system to execute GPF regeneration control safely and effectively. Therefore, in this study, logics were investigated for GPF temperature and amount of residual soot, and the logics were verified by a test vehicle. This paper describes the development process and verification results.
