Control device for automobile electric equipments

A device for controlling components of electrical equipment of a motor vehicle, such as flashing direction indicators, warning lights, side and rear lamps, dimmed headlights, main-beam headlights, windshield wipers and windshield washer, comprising:

• respective control switches actuatable by the driver to produce control signals;
• control circuit units for processing said control signals from said control switches to develop actuation signals;
• and
• control relays activated by said actuation signals of said control circuit units to supply said components;
• wherein said control switches comprise fugitive switches emitting a transient control signal when actuated;
• wherein said control circuit units each comprise at least one input shifting circuit for receiving the transient control signal;
• said device comprising synthesis means common to all said control circuit units for providing a common supply output to all said control circuit units;
• said synthesis means comprising a prepositioning circuit for providing a prepositioning output to all said control circuit units, and clock means for providing a general clock signal to said at least one input shifting circuit for shifting said transient control signal to the output of said input shifting circuit when the duration of the transient control signal is at least one clock period;
• each control circuit unit including a memorizing means having an input for receiving said transient control signal provided at the output of said input shifting circuit, and for memorizing said transient control signal, so as to provide said actuation signals for activating said control relays, and having an input connected to said prepositioning circuit to receive a prepositioning pulse corresponding to said prepositioning output when the device is electrically supplied, and including means responsive to receipt of said prepositioning pulse for resetting said memorizing means.
