摘要： A method for controlling a vehicle having an engine with an exhaust heat recovery system, includes generating a signal to control exhaust gas flow through an exhaust gas heat exchanger, and generating a diagnostic code based on the signal and a rate of change of coolant temperature. A vehicle has an engine and an exhaust heat recovery system with an exhaust gas heat exchanger and a temperature sensor. A controller for the vehicle is configured to (i) generate a signal to control exhaust gas flow through the exhaust gas heat exchanger, and (ii) generate a diagnostic code based on the signal and a rate of change of coolant temperature.

摘要： A method for controlling an exhaust gas recovery system for an engine includes generating a signal to control exhaust gas flow through an exhaust gas heat exchanger, and generating a diagnostic code based on a difference between coolant temperature downstream of the exhaust gas heat exchanger and coolant temperature downstream of the engine. A vehicle has an engine, and an exhaust heat recovery system with an exhaust gas heat exchanger, a first temperature sensor downstream of the engine, and a second temperature sensor downstream of the exhaust gas heat exchanger. A controller for the vehicle is configured to: (i) generate a signal to control exhaust gas flow through the exhaust gas heat exchanger, and (ii) generate a diagnostic code based on a difference between coolant temperature measured by the first and second temperature sensors.
