摘要： A fail-safe control method for a vehicle cooling system, in which an engine and a vehicle can be properly operated even when a water temperature sensor malfunctions. When only one of two water temperature sensors malfunctions, control may be performed so that an engine and a vehicle can properly operate. When both the two water temperature sensors malfunction, the fail-safe function of the flow rate control valve can be enabled to entirely prevent cooling water from being overheated, thereby improving the reliability of the operation of the vehicle.

摘要： A method for controlling an engine for a vehicle may include determining, by a controller, whether a symptom of an electrical failure where an opening state of a Purge Control Solenoid Valve (PCSV) is settled is sensed, increasing, by the controller, a failure sensing counter to a first reference value according to a state where the symptom of the electrical failure of the PCSV has been sensed is kept as a result of performing the failure sensing, and compensating, by the controller, a rotation number of the engine to increase the rotation number of the engine when the failure sensing counter exceeds the first reference value as a result of performing the counter increasing.

摘要： A coasting driving control method and system for a vehicle may determine virtual engine RPM for a current driving state using engine RPM, vehicle speed, and gear stage information by a controller when coasting is started with the clutch in the neutral position and outputs a downshifting instruction signal for a gear stage by the controller when the virtual engine RPM is less than a coasting engine RPM which is greater than an idling RPM by a predetermined value.

摘要： A failure diagnosis method of a coolant temperature sensor for a vehicle, may include determining, by a controller, whether or not it is in a flow stop state that stagnates the flow of coolant by a flow control valve; obtaining, by the controller, an engine outlet coolant model temperature when it is in the flow stop state; and diagnosing, by the controller, as a failure of an engine outlet-side outlet water temperature sensor when the coolant model temperature is equal to or greater than a reference temperature and the flow stop state is maintained by the flow control valve.
