The subject is to efficiently detect the sticking of changeover valves for realizing a plurality of supercharging modes in a vehicle provided with a plurality of superchargers, and also to realize preferable fail-safe in cases where the sticking is detected. In a vehicle, which is provided with: a primary turbo 300 and a secondary turbo 400, each of which is of an exhaust driven type; an exhaust changeover valve 210 and an intake changeover valve 21G, which are placed in a secondary exhaust passage 209 and a secondary intake passage 215 corresponding to the secondary turbo 400, respectively; and an intake bypass valve 218 placed in an intake bypass passage 217, an ECU 100 sets the opening / closing state of each changeover valve to an opening / closing state corresponding to a twin turbo mode at the time of engine stop, and it uses the drive control of each changeover valve which is necessitated in the transition to a single turbo mode at the engine start, thereby performing the sticking detection of the changeover valve at the same time.
