Magnetic rotary sensors have been used for the precise ascertainment of the rotary speed and position of drive shafts in double clutch transmissions, which have only a low degree of graduation precision due to the procedure of using impulse magnetisation. In order to minimise the disadvantages of this solution, elaborate electronic compensation is necessary in the transmission control module. Additional hardware and greater calculation times increase the costs for the entire system.
A rotary sensor has been developed together with one of the German system suppliers in the automobile industry, which has considerably improved the precision of graduation vis-à-vis the previous magnetic solutions and which makes additional electronic compensation superfluous.
