Abstract (en)
[origin: EP0976675A1] The drive force profile in normal operation, interfering forces being absent, is determined from a mathematical model. This profile is compared with the actual drive force measured during use. Departures of given magnitude, which are triggered by mechanical interference, stop or reverse door travel.
