Abstract

A control for a motorized deck lid pull down mechanism which does not require the use of mechanically activated limit switches for detecting deck lid positions or the presence of closing or sealing obstructions. Detection of specified pull down conditions as well as the presence of deck lid obstructions is achieved by monitoring the magnitude of motor current in relation to various predefined motor current thresholds. Engagement of the deck lid with obstructions during the pull down sequence will cause the motor current to exceed the closing and sealing thresholds, terminating or reversing the respective function.
