The present invention relates to a temperature control method of a diesel particulate filter (DPF) for a vehicle capable of easily regenerating soot by effectively controlling the regeneration temperature of a DPF. The temperature control method of a DPF for a vehicle according to the present invention comprises: a process of measuring the calorific value of a diesel oxidation catalyst (DOC); a process of obtaining a cooling rate correction value according to outdoor temperatures; a process of calculating and estimating a cooling rate using the cooling rate correction value; a process of calculating a post-injection fuel amount correction value by converting the cooling rate; and a process of adding the post-injection fuel amount correction value to a post-injection fuel amount according to the calorific value of the DOC. |
