A projection screen assembly, an optical engine assembly, a projection system, a vehicle, and a control method are provided. The projection screen assembly (1) includes a first connection structure (16), a first driving mechanism (12), and a projection screen body (11). The projection screen assembly (1) is connected to a vehicle body sheet metal (111) in a vehicle ceiling (110) through the first connection structure (16). The projection screen body (11) is connected to the first driving mechanism (12), and a projection screen rolls up into or extends out of the vehicle ceiling through driving of the first driving mechanism (12). There is no need to dispose an additional structure such as a hook on an interior trim member or a vehicle body beam for the projection screen assembly and the optical engine assembly, and there is no need to make a great change to a manufacturing process of the vehicle body beam or the interior trim member. Only space used for disposing the projection screen assembly is reserved between the vehicle body sheet metal and the interior trim member, so that production costs are reduced and arrangement of the projection screen assembly is facilitated.
