Method and apparatus for supplying power to the receiver of a motor vehicle locking system
First Claim
1. In a process for operating an electronic motor vehicle locking system including a receiver being mounted in the motor vehicle, being supplied by a battery power supply, and being remote-controlled by a handheld transmitter supplying coded control signals, and an operating switch for turning the power supply to the receiver on and off, a method for the clocked actuation of the operating switch, which comprises:
- operating the operating switch during a first waiting period with given intervals between turn-ons of the power supply, during which given intervals no power is supplied to the receiver; and
subsequently, if the receiver received no control signals during the first waiting period, operating the operating switch in a clocked fashion during a second waiting period with intervals between the turn-ons of the power supply being longer than the given intervals in the first waiting period.

Abstract
An electronic motor vehicle locking system has a receiver which is mounted in the motor vehicle, which is supplied by a battery power supply, and which is remote-controlled by a handheld transmitter supplying coded control signals. A clocked operating switch turns the power supply to the receiver on and off. The receiver may be remotely controlled with infrared light control signals or with radio control signals. A method for the clocked actuation of the operating switch includes operating the operating switch during a first waiting period with given intervals between turn-ons of the power supply; and operating the operating switch in a clocked fashion during a second waiting period after the first waiting period with intervals between the turn-ons of the power supply which are longer than the given intervals of the first waiting period, if the receiver received no control signals during the first waiting period. An apparatus for the clocked actuation of the operating switch includes a timer, as for instance a microprocessor with a clock pulse generator.

18. In an electronic motor vehicle locking system including a receiver being mounted in the motor vehicle, a battery power supply for supplying the receiver, a remote-controlled handheld transmitter for supplying the receiver with coded control signals, and an operating switch for turning the power supply to the receiver on and off, an apparatus for the clocked actuation of the operating switch, comprising a timer, said timer operating the operating switch during a first waiting period with given intervals between turn-ons of the power supply;
- and, if the receiver received no control signals during the first waiting period, said timer operating the operating switch in a clocked fashion during a second waiting period immediately following the first waiting period with intervals between the turn-ons of the power supply being longer than the given intervals.
