FIELD: internal combustion engines.
SUBSTANCE: invention can be used in vehicle internal combustion engines. Vehicle system comprises engine (230) with spark ignition, exhaust system (248) connected to engine (230), and controller (12). Exhaust system 248 comprises particulate filter 270. Controller (12) contains stored in long-term memory instructions to control operation of engine (230) and correction of one or more parameters of automatic controller of vehicle speed in case amount of soot accumulated in particulate filter (270) exceeds threshold quantity. Embodiment of the vehicle system and method of regenerating the particulate filter are disclosed.
EFFECT: technical result consists in application of more significant changes of engine torque during vehicle operation in automatic speed control mode.
