This utility model discloses a car spoiler correction control device, relating to the field of automation control technology. The device includes a spoiler with two sliding strips slidably connected to its outer surface. Each sliding strip has an adjustment mechanism and a tilting mechanism. By incorporating a support frame, a self-locking motor is activated, causing a threaded rod to rotate. This rotation moves the sliding strips upwards, which in turn move the spoiler upwards. The sliding strips, which can slide within the support frame, allow for smoother spoiler raising and lowering, helping to adjust aerodynamic performance according to vehicle driving conditions. The smooth raising and lowering of the spoiler optimizes airflow dynamics and maintains vehicle stability.
