Abstract

The invention relates to an electronic assembly (1) for a remote-control device for a motor vehicle. Said electronic assembly (1) is characterised in that it comprises: an electric power source (10); a supercapacitor block (11) with one or more super-capacitors, said supercapacitor block (11) being arranged in parallel with the electric power source (10); a transmitter/receiver (12) connected to said supercapacitor block (11); and a frequency amplifier stage (13) connected to said transmitter/receiver (12).

Claims

1. An electronic assembly for a remote-control device for a motor vehicle in which said electronic assembly comprises:

an electric power source;

supercapacitor block, said supercapacitor block being arranged in parallel with the electric power source;

a transmitter/receiver connected to said supercapacitor block; and

a frequency amplifier stage connected to said transmitter/receiver.

2. The electronic assembly as claimed in claim 1, further comprising a protection block for the supercapacitor block to limit a demand for current from the supercapacitor block to the electric power source.

3. The electronic assembly as claimed in claim 1, wherein the supercapacitor block has a value greater than or equal to ten millifarads.

4. The electronic assembly as claimed in claim 1, wherein the supercapacitor block has a value greater than or equal to one hundred and fifty millifarads.

5. The electronic assembly as claimed in claim 1, wherein the supercapacitor block includes a single supercapacitor having a value of two hundred and twenty millifarads.

6. A remote-control device for a motor vehicle wherein said remote-control device includes the electronic assembly as claimed in claim 1, a user control device and an antenna.
