The invention discloses a turbocharger and cam phase coordination control method and device, a controller and a storage medium. The method comprises the steps that when a target cam enters a scavenging mode, the difference value between the target intake manifold pressure and the actual intake manifold pressure is obtained; according to the difference value between the target intake manifold pressure and the actual intake manifold pressure, whether a dynamic cam phase coordination function is activated or not is judged; obtaining a dynamic cam phase coordination control coefficient corresponding to the activation condition of the dynamic cam phase coordination function; determining a target phase angle corresponding to the target cam according to the dynamic cam phase coordination control coefficient and an engine operation condition; and adjusting the phase of the target cam according to the target phase angle. 本申请公开了一种涡轮增压器与凸轮相位的协调控制方法、装置、控制器和存储介质。方法部分包括：当目标凸轮进入扫气模式时，获取目标进气歧管压力与实际进气歧管压力之间的差值；根据所述目标进气歧管压力与实际
