Abstract:
A canister purge control method for a vehicle can reduce the number of components of an active purge system provided in the vehicle. An active purge operation is performed using a pressure value measured by an intake pressure sensor, instead of a pressure value measured by a rear-end pressure sensor, after a purge control solenoid valve is fully opened.

Claim (Index 3):
The canister purge control method according to  claim 1 , wherein determining the target purge flow rate further comprises:\n determining, by the control unit, a density of fuel evaporation gas in purge gas, corresponding to a difference between the purge gas pressure value measured by the front-end pressure sensor and the pressure value measured by the intake pressure sensor, using previously input and stored first set data; and determining, by the control unit, the target purge flow rate from the determined density of the fuel evaporation gas and vehicle driving status information collected in real time from the vehicle, using previously input and stored second set data.
