SWITCHING DEVICE FOR THE TOP-END OF AN AUTOMOBILE VEHICLE STEERING COLUMN
First Claim
1. A switching device for the top-end of an automobile vehicle column comprising:
- a microcontroller;
at least two separate switching functional blocks, each block being connected to two signal inputs and two signal outputs of the microcontroller, one signal output or one signal input of which is only connected to a single functional block; and
four switches, each switch being connected to a signal input/output pair of the microcontroller separate from that of the other three of the same block, whereinat least two separate switching functional blocks only share either one output or one signal input the microcontroller, andthe microcontroller is configured for deducing, from a signal sent by at least one signal output having transited via at least one switching functional block and received at at least one signal input, the switching state of at least one switch of a switching functional block.

Abstract
The invention relates to a switching device for motor vehicle column top comprising a microcontroller (1). The latter comprises at least two distinct functional switching blocks (3, 5), each block being linked to two signal inputs (e1, e2, e3, e4) and two signal outputs (a, b, c) of the microcontroller (1), a signal output (a, b, c) or a signal input (e1, e2, e3, e4) of which is linked solely to a single functional block (3, 5) and comprising four switches (7, 9, 11, 13, 15, 17, 19, 21), each switch (7, 9, 11, 13, 15, 17, 19, 21) being linked to a signal input/output pair of the microcontroller (1) distinct from that of the other three of the same block (3, 5). At least two distinct functional switching blocks (3, 5) share only either one signal output (a, b, c), or input (e1, e2, e3, e4) of the microcontroller (1), and the microcontroller (1) is configured so as to deduce front a signal dispatched by at least one signal output (a, b, c) that has passed through at least one functional switching block (3, 5) and has been received at at least one signal input (e1, e2, e3, e4), the state of switching of at least one switch (7, 9, 11, 13, 15, 17, 19, 21) of a functional switching block (3, 5).
