    摘要： The invention relates to a method for producing a component (5) for a vehicle, having the following steps: -(A) providing a workpiece made of a heat-treatable steel material (2), said workpiece being provided with a zinc-containing coating on both sides, -(B) at least partly heating the workpiece to a temperature above Ac1, -(C) introducing the at least partly heated workpiece into a hot-forming and/or press-hardening tool which comprises at least one punch and at least one die, -(D) closing the tool by moving the punch and/or the die relative to each other and hot-forming and/or press-hardening the workpiece, wherein at least one region of the heated workpiece is cooled in the closed tool such that a hardened microstructure is at least partly formed. The aim of the invention is to provide a method for producing a component for a vehicle, a component for a vehicle, and a use of the component, wherein together with an active corrosion protection, a sufficient component strength in the event of a crash and a sufficient service life expectancy can be ensured in particular with cyclical loading. This is achieved in that the workpiece has a first surface (3) with a smaller layer thickness of the zinc-containing coating than the second surface (4) of the workpiece. The workpiece is introduced into the hot-forming and/or press-hardening tool such that the first surface (3) of the workpiece is positioned on the side which is largely loaded with pressure and/or tension during the component manufacturing process, in particular the tool side which has a largely concave shape.
