The present invention provides a vehicle system comprising: an engine including a combustion chamber in which an air-fuel mixture is combusted to generate energy, an intake manifold supplying air to the combustion chamber, an injector supplying fuel to the combustion chamber, and an exhaust Exhaust manifold of exhaust gas produced by the combustion of the air-fuel mixture and passed through the exhaust pipe; hybrid starter generator (HSG), which generates electricity by starting the engine or by using energy generated in the engine; soot filter, fitted to on the exhaust pipe and collect particulate matter (smoke) contained in the exhaust; and a control unit that controls the operation of the injector and controls the operation of the HSG, wherein, when the amount of soot is greater than a predetermined amount, the control unit changes the size of the load of the HSG Increase the predetermined load until the temperature of the smoke filter reaches the predetermined temperature.
Description
[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2017-0139163 filed with the Korean Intellectual Property Office on October 25, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a vehicle system including a soot filter and a method of heating the soot filter, wherein the soot filter can pass through the soot filter according to the The temperature of the filter regulates the load of the hybrid starter and generator to rapidly heat the soot filter. Background technique [0004] General vehicles run by using energy generated by burning an air-fuel mixture in an engine. Recently, hybrid vehicles are increasingly being used in response to tightened exhaust regulations and to improve fuel efficiency. [0005] A hybrid vehicle is a vehicle that uses two or more sources of power. In general, a hy...
