PROBLEM TO BE SOLVED: To prevent the elevation of a door glass when the door glass is indicated so as to be lifted under the state, in which trouble is generated in a pulse encoder. SOLUTION: This motor driving controller is started by the rise and fall of a pulse signal generated from a pulse encoder under the state, in which there is an indication that a door glass is lowered by operating a switch, and whether or not a timer count value T is T>=2.the moving average value t0 of pulse width is decided. 1 is set to a flag F while regarding as the generation of a pulse lack at the time of T>=2.t0 . When an indication is conducted subsequently so that the door glass is lifted, the elevation of the door glass is prevented. |
