INPUT DATA SWITCHING DEVICE AND ELECTRIC POWER STEERING DEVICE USING IT

摘要

PROBLEM TO BE SOLVED: To secure the linearity of input data by precisely correcting a tolerance generated between both devices when switching the input data.;SOLUTION: This input data switching device adds a tolerance of predetermined-multiplied data after conversion with respect to predetermined-multiplied times of data before conversion stored in a tolerance storage means to predetermined-multiplied input data after conversion, when the predetermined-multiplied the input data before conversion obtained by multiplying analogue input data by predetermined multiplication according to a resolution of a first A-D conversion part 52a and then converting it to digital data with the first A-D conversion part 52a are switched to the predetermined-multiplied data after conversion obtained by converting the analogue input data to the digital data with a second conversion part 52b and then multiplying it by the predetermined multiplication.;COPYRIGHT: (C)2007,JPO&INPIT
