System with optical or radio remote control for closing motor vehicles

A system with optical or radio remote control for initializing a system for locking and/or unlocking doors of motor vehicles, comprising:

• a portable transmitter corresponding to a key for a motor vehicle, said transmitter broadcasting a digital code upon actuation by a user for locking and/or unlocking doors of the motor vehicle;
• said broadcast digital code received by a receiver in the motor vehicle, which receiver controls a relevant lock or locks of the doors of the motor vehicle after a comparison and correlation of the received digital code with a predetermined code stored in the receiver;
• the digital code being initialized as the predetermined code at least when the motor vehicle is first used and, possibly when changes are later made to the digital code, being reinitialized, that is fixed for following actuations, by storing in the receiver the broadcast digital code as a new predetermined code that replaces a previous predetermined code, the broadcast digital code being also storable in the transmitter;
• an external diagnostic device at least an external signal for (re)initialization, that is for initialization and/or for reinitialization, the receiver being switched only after reception of the external signal to a (re)initialization readiness status before the receiver is (re)initialized;
• the motor vehicle having a diagnostic interface for electrical testing of motor vehicle units in the motor vehicle, said diagnostic interface connected to said receiver;
• and
• the receiver being switchable to the (re)initialization readiness status only after reception of the external signal fed to the receiver via the diagnostic interface from the external diagnostic device and by a further signal fed to the receiver, the further signal being generated by inserting into an associated lock and turning a mechanical key individually assigned to the motor vehicle;
• wherein a new code signal is generated using the transmitter and is transmitted to the receiver, the new code signal then being stored as a new predetermined code signal in the receiver.

• an external diagnostic device for supplying at least an external signal for (re)initialization, that is for initialization and/or for reinitialization, the receiver being switched only after reception of the external signal to a (re)initialization readiness status before the receiver is (re)initialized;
• the motor vehicle having a diagnostic interface for electrical testing of motor vehicle units in the motor vehicle, said diagnostic interface connected to said receiver;
• and
• the receiver being switchable to the (re)initialization readiness status only after reception of the external signal fed to the receiver via the diagnostic interface from said external diagnostic device and by a further signal fed to the receiver, the further signal being generated in response to the digital code broadcast by the transmitter;
• wherein a new code signal is generated using the transmitter and is transmitted to the receiver, the new code signal then being stored as a new predetermined code signal in the receiver.

A method, using optical or radio remote control for initializing a system for locking and/or unlocking doors of motor vehicles, comprising:

• broadcasting, using a portable transmitter corresponding to a key for a motor vehicle, a digital code upon actuation by a user for locking and/or unlocking doors of the motor vehicle;
• receiving said broadcast digital code by a receiver in the motor vehicle, which receiver controls a relevant lock or locks of the doors of the motor vehicle after a comparison and correlation of the received digital code with a predetermined code stored in the receiver;
• initializing the digital code as the predetermined code at least when the motor vehicle is first used and, possibly when changes are later made to the digital code, reinitializing the digital code, that is fixed for following actuations, by storing in the receiver the broadcast digital code as a new predetermined code that replaces a previous predetermined code, the broadcast digital code being also storable in the transmitter;
• supplying, using an external diagnostic device, at least an external signal for (re)initialization, that is for initialization and/or for (re)initialization, the receiver being switched only after reception of the external signal to a (re)initialization readiness status before the receiver is (re)initialized;
• providing in the motor vehicle a diagnostic interface for electrical testing of motor vehicle units in the motor vehicle, said diagnostic interface connected to said receiver;
• and
• switching the receiver to the (re)initialization readiness status only after reception of the external signal fed to the receiver via the diagnostic interface from the external diagnostic device;
• wherein a new code signal is generated using the transmitter and is transmitted to the receiver, the new code signal then being stored as a new-predetermined code signal in the receiver.
