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 7):
A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:\n program instructions that open a purge control solenoid valve disposed on a purge line between a canister and an engine intake system to enable a canister purge operation during running of an engine of a vehicle; program instructions that start an active purge pump of an active purge system provided in the vehicle, the active purge pump being disposed on the purge line; program instructions that recognize a purge gas pressure value measured by a front-end pressure sensor disposed on the purge line, on a front end side of the active purge pump, and a pressure value measured by an intake pressure sensor disposed on an engine intake system side to which the purge line is connected; program instructions that determine a target purge flow rate using 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; and program instructions that control an operation of the active purge pump at an operating speed corresponding to the determined target purge flow rate.
