AI Technical Summary

Problems solved by technology

However, it has the disadvantage that degradation of any on-off switch or incorrect closing of the contacts of one of the on-off switches has an effect on the voltage
The measured voltage may thus differ from the corresponding desired voltage for a given controller, and may result in commands to functions not intended by the user

Abstract

The invention relates to an electrical architecture (1) for a motor vehicle switch, which comprises a first control (C1), a second control (C2), and a third control (C3), said first control (C1) being connected by a first direct wire connection (FD1) to a first output (S1) of a microprocessor (2), and said second control (C2) being connected by a second direct wire connection (FD2) to a second output (S2) of said microprocessor (2). Said third control (C3) is connected by a first indirect wire connection (FI1) to said first output (S1) and to said second output (S2) of said microprocessor (2). The electrical architecture (1) according to the invention is used particularly advantageously in the automotive field.

Description

technical field [0001] The invention relates to an electrical architecture for a motor vehicle switch, which is used eg to control a radio. More specifically, the invention relates to electrical architectures for motor vehicle switches, using diodes and wiring. Background technique [0002] The architecture used in a motor vehicle, in particular for controlling the radio, can be implemented in different ways. [0003] The first type of architecture involves matrix architectures. This type of architecture includes, for example, three inputs and three outputs connected to a microprocessor. [0004] Every input intersects every output. As a general rule, a contact system is installed at the junction of each input and output. Depending on the activation of the contact system, an electrical connection is created between the input and output of the microprocessor. Thus, when the microprocessor sources a current via a given output, the output detects, on the input connected to...
