Remote-control system for closures
First Claim
1. A remote-control system for closures, comprising:
- a portable hand held transmitter which generates and radiates directed coded control signals upon actuation of a transmission key on the hand held transmitter;
at least one first receiver unit arranged on a motor vehicle, which first receiver unit it tuned to receive the control signals radiated from the hand held transmitter, and which triggers switching effects on a remotely controllable vehicle locking device after received control signals have been identified as acceptable;
at least one second receiver unit tuned to receive control signals radiated as a result of the actuation of the transmission key of the hand held transmitter for remotely controlling a remotely controllable access control device external to the motor vehicle, said second receiver unit being arranged outside the motor vehicle and triggering switching effected on the access control device after received control signals have been identified as acceptable;
electrical means for preventing at least the triggering of switching effects by the second receiver unit simultaneously with the triggering of switching effects by the first receiver unit in response to a control signal, which is radiated by the hand transmitter as a result of one single actuation of said transmission key and is received simultaneously by the first and the second receiver unit, andat least one additional transmitter fixed to the motor vehicle, said transmitter being randomly electrically activatable from a passenger space of the motor vehicle independently of the hand transmitter, said transmitter being arranged on the outside of the motor vehicle for direct radiation to the outside of control signals coded in accordance with the control signals radiated by the hand transmitter.

Abstract
A remote-control system for closures with a movable hand transmitter with at least one transmission key, this transmitter generating and radiating directed coded control signals upon actuation of the transmission key of the hand transmitter. At least one first receiver unit is tuned to receive the control signals radiated from the hand transmitter and is arranged on a motor vehicle and triggers switching effects on a remotely controllable vehicle locking after the received control signals have been identified as acceptable. At least one second receiver unit is tuned to receive control signals radiated as a result of the actuation of the transmission key of the hand transmitter for remotely controlling a remotely controllable access control device external to the motor vehicle. This second receiver unit is arranged outside the motor vehicle and triggers switching effects on the access control device after the received control signals have been identified as acceptable. An electrical circuit is provided for preventing at least the triggering of switching effects by the second receiver unit when the control signal radiated as a result of a single actuation of the transmission key of the hand transmitter is received simultaneously by the first and the second receiver unit, by causing to arrive at the second receiver unit only a control signal which significantly differs from the control signal radiated as a result of the actuation of the transmission key of the hand transmitter for remotely controlling the access control device. At least one transmitter is fixed to the motor vehicle, this transmitter being randomly electrically activatable from a passenger space of the motor vehicle independently of the hand transmitter. The transmitter is arranged on the outside of the motor vehicle for direct radiation to the outside of control signals coded in accordance with the control signals radiated by the hand transmitter. This ensures that only one code has to be impressed on the control signals of the hand transmitter in order to make it possible to use the hand transmitter for the direct remote control both of the vehicle locking and of the access control device.
