Abstract
A method for improving engine start performance of a vehicle performing engine synchronization at the time of the engine start may include performing a first synchronization task from an engine stop position stored when the engine stops in immediately previous traveling, and performing the first synchronization task when a crank signal of a crank sensor is first input to an engine position management (EPM) module.
Claims9
A method for improving engine start performance of a vehicle, the method comprising:
- performing, by a controller, a first synchronization task from an engine stop position stored when an engine stops in immediately previous traveling, and
- performing the first synchronization task when a crank signal of a crank sensor is first input to an engine position management (EPM) module.
A method for improving engine start performance of a vehicle, the method comprising:
- inputting a crank signal from a crank sensor to an engine position management (EPM) module after an engine starts;
- determining, by a controller, whether the crank signal is a first input signal after the engine starts;
- determining, by the controller, whether a storage angle of an engine stop position stored at a time when the engine stop in immediately previous traveling is valid when the inputted crank signal is determined as the first input signal after the engine starts;
- and
- performing, by the controller, engine synchronization and a first synchronization task performing calculation and setting for first injection and first ignition in an application software (ASW) and a basic software (BSW) by performing the engine synchronization at the storage angle and activating the first synchronization task when the storage angle is determined as being valid.
