The invention discloses a vehicle stand column upper decoration plate and a forming optimization method thereof, relates to the technical field of vehicle parts, and can solve the problem that an injection molding wrapping piece is prone to being broken down in the low-pressure injection molding process. The vehicle column upper trim panel is formed through low-pressure injection molding and comprises a base and a wrapping piece. Wherein the base is provided with a first molded surface, a second molded surface and a transition structure, the first molded surface is assembled in a visible area in a vehicle, and the second molded surface is assembled in an invisible area in the vehicle; the transition structure is fixedly connected between the second molded surface and the first molded surface; the covering part covers the same side surfaces of the first molded surface, the transition structure and the second molded surface; the transition structure comprises a first plate, a second plate and a third plate which are sequentially and smoothly connected end to end, the thickness of the first plate and the thickness of the third plate are gradually reduced in the direction towards the second plate, and the thickness of the second plate is smaller than the minimum value of the thickness of the first plate and the thickness of the third plate. The vehicle stand column upper decoration plate is assembled on a vehicle body metal plate.
