Attitude controlling system for vehicle-supported equipment

摘要

A tilt steering mechanism, a telescopic steering mechanism and a seat attitude adjusting mechanism are controlled in their attitudes by an electric motor such that the respective attitudes are automatically set into a retreat attitude where the driver easily gets on and off a vehicle upon boarding/alighting, and into a driving attitude assumed before retreat upon the completion of boarding. Whether or not the driver is about to get on and off the vehicle is judged in accordance with the status of an ignition switch, status of a door switch, vehicle speed, status of a parking brake, shift lever position of a transmission, etc. A change speed of attitude is monitored during energization of the electric motor and, if the change speed is less than a predetermined value, this is judged as the presence of overload and the electric motor is stopped.
