Abstract:
1. A low pressure EGR (Exhaust Gas Recirculation) system control apparatus of an internal combustion engine of a vehicle, comprising: an atmosphere temperature detecting portion that detects atmosphere temperature of a driving region of the vehicle; an air conditioner switch that outputs ON/OFF signal of an air conditioner; a wiper switch outputting ON/OFF signal of a wiper; and a control portion that uses the atmosphere temperature to determine a monthly average relative humidity, wherein the control portion includes a data map having monthly average lowest temperature of the driving region, the monthly average relative humidity of the driving region, and monthly average accumulated rainfall of the driving region, and limits the operation of a low pressure EGR system such that condensate is not formed therein, when the monthly average relative humidity and the monthly average accumulated rainfall respectively exceed a predetermined value.
