Abstract

Disclosed are a method and an apparatus for controlling heating of a fuel filter. The method may include a first step of measuring a temperature of intake air that enters an engine, a second step of measuring a temperature of cooling water, and a third step of, upon input of a key-on signal, controlling whether to activate or deactivate a heater for the fuel filter in response to the measured temperatures of the intake air and the cooling water.

Description

technical field [0001] In general, the present invention relates to a technique for controlling heating of a fuel filter, and more particularly, to a method and apparatus for controlling heating of a fuel filter using an A temperature sensor instead of a fuel temperature sensor in the fuel filter implements the heating logic for the fuel filter. Background technique [0002] Generally, in a fuel filter for a vehicle in a cold environment, such as in winter, fuel may undergo solidification due to cold air to clog the fuel filter, resulting in a failure to start or an engine stop. Therefore, in order to prevent such a problem, a control action for heating the fuel filter is required. [0003] A conventional solution is to have a thermostat in the fuel filter so the heater operates in response to temperature. However, if the thermostat malfunctions or malfunctions, there can be problems with starting performance, such as a failed start or engine stalling. [0004] To solve t...
