The invention provides a method and apparatus for controlling the speed of a stairlift (10). The speed of rotation of the carriage (12), whilst traversing bends in the rail (11), is monitored and the speed of the carriage drive motor (13) then controlled in reaction to the speed of rotation. A 3-axis gyroscope (31) is preferably used to monitor the speeds of rotation of the carriage (12) and the outputs from this gyroscope (31) may be processed to provide different degrees of speed control.
