Patent ID: 7571073

Claim:
A system ( 1 ) for acquiring the angular position of a gas twist grip ( 2 ) in a motorcycle; the acquisition system ( 1 ) comprises: a fixed supporting body ( 3 ); a rotating shaft ( 4 ) turnable mounted in the supporting body ( 3 ); a transmission device ( 6 ) mechanically connected to the gas twist grip ( 2 ) and to the revolving shaft ( 4 ) to transmit the motion of the gas twist grip ( 2 ) to the revolving shaft ( 4 ) itself; a main angular position sensor ( 10 ), which is carried by the supporting body ( 3 ), is coupled to the revolving shaft ( 4 ) to determine the angular position of revolving shaft ( 4 ), and is adapted to provide two reciprocally redundant measures of the angular position of the revolving shaft ( 4 ); an angular control position sensor ( 11 ), which is separate and independent from the main angular position sensor ( 10 ), is carried by the supporting body ( 3 ), is coupled to the revolving shaft ( 4 ) to determine the angular position of the revolving shaft ( 4 ), and is adapted to provide two reciprocally redundant measures of the angular position of the revolving shaft ( 4 ) that are independent from the two reciprocally redundant measures of the angular position of the revolving shaft ( 4 ) provided by the main angular position sensor ( 10 ).
