PURPOSE:To make a switching mode proper at all times for a real time by detecting the direction of change of a current deviation at every time of control, deciding the keeping of the direction of the change of the current deviation within the range of the direction of a reference change and varying the switching mode by the result of the decision. CONSTITUTION:A current-deviation change-direction ...

In a sliding roof for an automobile, a rigid sliding lid is slidably guided on lateral guide rails, a movable lid liner participating in the lid displacements being connected to the sliding lid, which liner is likewise displaceable on the guide rails. In order to achieve a step-free, flush joint of the lid liner, when the sliding lid is closed, with a surrounding fixed roof liner, and to avoid dam...

PURPOSE:To enable quick reset to a control target speed by switching the speed change stage to the low speed side while resetting an integrated deviation of vehicle speed upon decision that the control target speed can not be maintained. CONSTITUTION:A vehicle speed controller comprises a deviation integrating means 5 for integrating the deviation between a control target speed set by a target veh...
