| 摘要 |
An exhaust heat recovery system (EHRS) for a vehicle is operable to direct exhaust heat to a vehicle transmission under certain operating conditions. In some embodiments, the EHRS may also direct exhaust heat to a heater for vehicle passenger compartment. Preferably, the EHRS is controllable to manage available exhaust heat according to vehicle operating conditions, by prioritizing the heat flow among the engine, the transmission, and the vehicle heater. The EHRS may also operate in a bypass mode during which exhaust heat is not directed to the engine, the transmission or the vehicle heater. A method of managing exhaust heat recovery on a vehicle having an EHRS is also provided.
