Method and apparatus for the compensation of dynamic error signals of a chopped - hall - sensor

摘要

A method for compensation of dynamic error signals of a chopped - hall - sensor (10; 50), which at least one hall - sensor element (12; 52, 54) having a plurality of terminal pairs (14, 16, 18, 20, 22, 24, 26, 28; 56, 58, 60, 62, 64, 66, 68, 70) for injection of an excitation - current (i) by means of the hall - sensor element (12; 52, 54) and for picking up a hall - voltage (vhall1, vhall2; vhp1, vhn1, vhp2, vhn2), wherein the pairs of (14, 16, 18, 20, 22, 24, 26, 28) for impressing of the excitation - current (i) and for the tracing of the hall - voltage (vhall1, vhall2; vhp1, vhn1, vhp2, vhn2) in a first and / or second direction of rotation (30, 32; 72, 74) are switched over, characterized in that the at the terminal pairs (14, 16, 18, 20, 22, 24, 26, 28; 60, 62) during the changeover in the first direction of rotation (30; 72) tapped hall - voltages (vhall1; vhp1, vhn1) are arranged at the terminal pairs (14, 16, 18, 20, 22, 24, 26, 28; 68, 70) during the changeover in the second..
