A position detection device enables an accurate detection of a position of a moving object. Two cam surfaces are formed on an outer peripheral surface of a rotary body ( ) and micros-witches ( ) are brought into contact with respective cam surfaces and a logic (L, H) can be established based on signals from two switches.

An open/close body control system for a vehicle can stabilize outputs of a pair of electrically operated motors (M , M ) which drive an open/close body for a vehicle. Speeds of the electrically-operated motor (M , M ) are synchronously controlled such that predictive positions (XLt&plus;1, XRt&plus;1) of electrically-operated motor (M , M ) after a lapse of a unit time gradually approach a target position (XTRG) calculated based on present positions (XLt, XRt) and a target speed (&Dgr;XTRG) of the electrically-operated motors (M , M ).

Movable body control system for vehicle

In an open roof operating method, when a pulse of a value equal to or greater than a set value is inputted to an ECU when the outputting of motors is stopped, simultaneous operations of respective components are stopped. By adding a sequential non-interference operation flow to a simultaneous operation flow, the interference among respective components under specific conditions can be obviated.
