A system for controlling a particulate filter temperature |
摘要 |
A system (10) for controlling the temperature of a particulate filter (38) coupled to an exhaust outlet (36) of an internal combustion engine (12) includes a controller (18) responsive to volumetric flow and temperature of exhaust gas to determine a filter regeneration parameter. In a hybrid electric-engine vehicle application, various control strategies are implemented as a function of the regeneration parameter to control exhaust gas temperature suitably for proper regeneration of the particulate filter (38). Such strategies include shifting the duty cycle of the engine (12) toward lower engine speed operation along lines of constant power output, modifying the ratio of electrical power and engine power and controlling recharging of the battery (30) supplying electrical energy to the vehicle's electric drive motor under vehicle deceleration conditions. In vehicle applications including a transmission coupled directly to the engine (12), shift points of the transmission are modified as a function of the regeneration parameter to control exhaust gas temperature. |
