Abstract
Official abstract text for this publication.
A motor vehicle computer includes an input port connected to a crankshaft sensor and a module for processing signals received from the crankshaft sensor. The computer includes: a first adapting module, suited to making the signals, provided by a crankshaft sensor of a first type, conform to an input predefined format of the processing module; a second adapting module, suited to making the signals, provided by a crankshaft sensor of a second type, conform to the input format of the processing module; a routing unit suited to connecting the input port to the first or to the second adapting module; a unit for detecting the type of the crankshaft sensor connected to the input port; and a unit for commanding the routing unit according to the type of crankshaft sensor detected.
First claim
Opening claim text (preview).
The invention claimed is: 1. A motor vehicle computer ( 10 ) including an input port ( 11 ) connected to a crankshaft sensor ( 20 ) and a module ( 12 ) for processing signals received from said crankshaft sensor, the computer comprising: a first adapting module ( 14 ), suited to making the signals, provided by a crankshaft sensor of a first type (A), conform to an input predefined format of the processing module ( 12 ), a second adapting module ( 15 ), suited to making the signals, provided by a crankshaft sensor of a second type (B), conform to said input format of the processing module ( 12 ), routing means ( 13 ) suited to connecting the input port ( 11 ) to the first adapting module ( 14 ) or to the second adapting module ( 15 ), means for detecting the type of the crankshaft sensor ( 20 ) connected to the input port ( 11 ), and means for commanding the routing means ( 13 ) according to the type of crankshaft sensor ( 20 ) detected. 2. The computer ( 10 ) as claimed in claim 1 , wherein one of the crankshaft sensors ( 20 ) corresponds to a variable reluctance sensor. 3. The computer ( 10 ) as claimed in claim 2 , wherein the other crankshaft sensor ( 20 ) corresponds to a Hall effect sensor. 4. The computer ( 10 ) as claimed in claim 3 , wherein the detecting means include a diagnostic module ( 16 ) for the crankshaft sensor. 5. The computer ( 10 ) as claimed in claim 2 , wherein the detecting means include a diagnostic module ( 16 ) for the crankshaft sensor. 6. The computer ( 10 ) as claimed in claim 1 , wherein the detecting means include a diagnostic module ( 16 ) for the crankshaft sensor. 7. The computer ( 10 ) as claimed in claim 6 , wherein the diagnostic module ( 16 ) takes the form of a resistance bridge connected to the input port ( 11 ) of the computer ( 10 ), the midpoint of which is connected to the processing module ( 12 ) that analyzes the voltage level of the midpoint of the resistance bridge, and compares it with reference values previously stored in an electronic memory of the processing module ( 12 ).
