ABSTRACT:
A control apparatus for an automotive power-operated convertible roof includes means for detecting movement of a vehicle, drive means for opening and closing the automotive convertible roof, a relay for preventing the opening and closing of the convertible roof and roof opening/closing controlling means for controlling the relay to inhibit the opening and closing of the convertible roof when the velocity of the vehicle detected by the movement state detecting means is not below a predetermined speed level. As a result, is unlikely that the convertible roof will be opened or closed erroneously during movement of the vehicle, nor is there the possibility of damage to the roof caused by an excessive wind pressure during opening or closing of the roof. In addition, no special consideration is needed about the possibility of floating or vibration of the vehicle body caused by wind pressure acting on the roof, and vehicle stability is enhanced.
