The central locking, in particular for motor vehicle, 2004.

摘要

A central locking, in particular for motor vehicle, 2004, comprises several electrical motors 1 and a timer 11 adapted to be tripped by at least one switch 13 during the passage of that - treatment of a first has a second position, and activating the motors in a direction for a given time predetermined. It is characterized in that a first stage 23 controlled by this switch emet a first signal has two levels which represent the two positions of this latter stage which, during the change of position cited above of the switch, sets off the operation of a second stage 15 so that it emit a signal in the form of a ramp which, in a third stage 21, is compared with a reference signal has a constant level. A control stage 25 starts the motors for as long as the first signal has two levels is located at the level which corresponds to the second position of the switch and that, in the same time the signal from the stage is at the level comparator, which results from the initial level of the signal in the form of a ramp, and it stopped in addition, the operation of the motors to the direction gives.
