Abstract: Disclosed is an apparatus for changing a mode in a proportional integral differential (PID) controller, which removes an impact generated in a mode change and stably performs the mode change when the operational mode of the PID controller is changed from a manual mode into an automatic mode or vice versa. The apparatus includes a PID operator configured to generate a driving signal by performing a PID operation in an automatic mode or a manual mode based on a manual mode change signal or an automatic mode change signal; a manual mode buffer configured to process the generated driving signal and output the processed driving signal to a load driver when the manual mode change signal is generated; and a speed difference integral calculator configured to analyze the generated driving signal and output the analyzed driving signal to the PID operator when the automatic mode change signal is generated.

Abstract: An apparatus for mounting a roof rack including a roof garnish and a bracket for mounting a roof rack, in which the roof garnish and the roof rack mounting apparatus can be separately mounted on a vehicle panel. Due to a simple construction, the roof rack mounting apparatus can be conveniently operated and the mounting costs and time thereof can be reduced.
