CONTINUOUSLY VARIABLE TRANSMISSION OIL CONTROL METHOD IN HYBRID VEHICLE

摘要

PURPOSE: A method for controlling continuously variable transmission(CVT) oil controlling method for hybrid vehicles is provided to prevent the damage of CVT parts due to heat by maintaining the rev count of an engine. CONSTITUTION: Whether the temperature of CVT oil is higher than or equal to pre-set temperature is verified(S10). The flux of oil supplied to a CVT from an oil cooler is limited(S20). The state of transmission range is verified(S30). Whether the inclination angle of a road is more than or equal to a pre-set angle is verified(S40). The limitation with respect to the flux of oil from the oil cooler is released based on the verification result(S50).
