An object of this invention is to efficiently warm up a catalyst and keep its temperature. Provided is a drive system, including: an internal combustion engine; a catalytic unit configured to purify an exhaust gas from the internal combustion engine; a motor used for at least one of drive or regeneration; and a flow path formed so as to allow an oil-based medium for lubricating the motor to flow in the vicinity of the catalytic unit. The oil-based medium is heated in the motor and exchanges heat in the catalytic unit to heat the catalytic unit.
