A drive control system for vehicle mounted, electrically driven devices comprising:

• a plurality of support means for supporting a plurality of vehicle mounted, electrically driven devices each in a movable manner;
• a plurality of electric motor drive mechanisms arranged to drive each associated vehicle mounted device;
• a motor driver for independently energizing the electric motor of the respective motor drive mechanism;
• input means for inputting a drive command to each of the motor drive mechanisms;
• position detecting means for detecting that any one of the vehicle mounted devices has reached its limit position;
• first detecting means for detecting that an ignition key is inserted into a receptacle of an ignition switch mounted on the vehicle;
• second detecting means for detecting an opening or closing of a door of the vehicle;
• and control means including means for controlling the energization of the motor through one of the motor drivers connected thereto in response to the drive command from the input means which selects a particular one of the motor drivers, and means for storing information indicating energization of at least one of the motors responsive to the input means when the first detecting means indicates that the ignition key is not inserted, said controlling means being operative in response to the absence of the storage to control the energization of the electric motor or motors except one which is energized when an engine key switch of the vehicle is off, through associated motor driver or drivers, until a corresponding one of the position detecting means has detected that the limit position is reached when the second detecting means indicate a closing of the door and when the first detecting means indicates that the ignition key is not inserted.

A drive control system for vehicle mounted, electrically driven devices comprising:

• support means for supporting at least one vehicle mounted device in a movable manner;
• an electric motor drive mechanism for driving the vehicle mounted device;
• a motor driver for energizing an electric motor of the motor drive mechanism;
• input means for inputting a drive command to the motor drive mechanism;
• position detecting means for detecting the position of the vehicle mounted device;
• status detecting means for determining a status change in a manner corresponding to a status of the vehicle;
• control means for energizing the motor in response to an input from the input means when the status detecting means indicates the vehicle is not being operated and for de-energizing the motor if the detected position coincides with a standby position;
• and standby position presetting means for presetting the vehicle mounted device to a standby position as it is positioned by the energization of the motor when the control means commands the motor driver to energize the motor in response to an output from the input means under the condition that the status detecting means indicates a given status of the vehicle.

• status detecting means presenting a status change in a manner corresponding to a status of the vehicle;
• control means including motor driver commanding means for commanding the energization of the motor associated with one of the vehicle mounted devices in response to an input from the input means, the position detecting means indicating that the vehicle mounted devices being out of a standby position when the status detecting means indicates the vehicle is not being driven, said motor driver commanding means subsequently commanding the motor driver to de-energize the motor when the position detecting means indicates that the position of the vehicle mounted device coincides with the standby position;
• and standby position presetting means for presetting one of the vehicle mounted devices to a preselected standby position therefor as the vehicle mounted device is positioned by the energization of the electric motor when the control means commands the motor driver to energize such motor in response to an input from the input means and when the status detecting means indicates a given status of the vehicle.
