1. A vehicle control method for a vehicle including an internal combustion engine, a transmission structured to perform gear change for output of the internal combustion engine, a supercharger structured to supercharge intake air of the internal combustion engine, a recirculation passage connected to an intake passage of the internal combustion engine so as to bypass a compressor of the supercharger, a recirculation valve disposed in the recirculation passage, a turbine of the supercharger disposed in an exhaust passage of the internal combustion engine, a bypass passage connected to the exhaust passage so as to bypass the turbine, and a waste gate valve disposed in the bypass passage, the vehicle control method comprising:
in response to upshift of the transmission, opening the recirculation valve and the waste gate valve and retarding an ignition timing; and
in response to completion of the upshift of the transmission, implementing termination of the retardation of the ignition timing and closure of the recirculation valve at different timings,
wherein the timing of the closure of the recirculation valve is determined depending on an engine speed of the internal combustion engine or a gear ratio of the transmission.
