Abstract
An apparatus and method for controlling an LDC of a hybrid vehicle are provided. The apparatus includes a determining controller that receives state information of an auxiliary battery, while the LDC is being operated in a first mode based on a detected voltage, and that determines whether an entry condition for a second mode based on a current is satisfied. An arithmetic controller calculates a charging current compensation value of the auxiliary battery when the entry condition for the second mode is satisfied and a mode controller enters the second mode and that controls the LDC based on the charging current compensation value of the auxiliary battery when the entry condition for the second mode is satisfied.
Claims20
An apparatus for controlling a low direct current-direct current (DC-DC) Converter (LDC) of a hybrid vehicle, comprising:
- a determining controller configured to receive state information of an auxiliary battery, while the LDC is being operated in a first mode based on a detected voltage and determine whether an entry condition for a second mode based on a current is satisfied;
- an arithmetic controller configured to calculate a charging current compensation value of the auxiliary battery when the entry condition for the second mode is satisfied;
- and
- a mode controller configured to enter the second mode and to operate the LDC based on the charging current compensation value of the auxiliary battery when the entry condition for the second mode is satisfied.
A method for controlling a low direct current-direct current (DC-DC) Converter (LDC) of a hybrid vehicle, comprising:
- determining, by a controller, whether an entry condition for a second mode based on a current is satisfied by receiving state information of an auxiliary battery while the LDC is being operated in a first mode based on a detected voltage;
- entering, by the controller, the second mode when the entry condition for the second mode is satisfied;
- calculating, by the controller, a charging current compensation value of the auxiliary battery;
- and
- operating, by the controller, the LDC based on the charging current compensation value of the auxiliary battery.
