A control method for a mild type hybrid electric vehicle is provided. The method determining whether a coasting condition is satisfied and initiating coasting when the coasting condition is satisfied. A reacceleration intention is then detected and a torque of a mild hybrid starter & generator (MHSG) is increased in response thereto. A revolutions per minute (RPM) of the MHSG is compared with a RPM of an engine an engagement of the MHSG with the engine is attempted when the RPM of the MHSG corresponds to the RPM of the engine. The RPM of the MHSG is then synchronized with the RPM of the engine. When the MHSG is successfully engaged with the engine, the torque of the MHSG is increased to inject a fuel to the engine.
