Title:
SIGNAL CONTROL APPARATUS AND ELECTRIC POWER STEERING APPARATUS USING THE SAME
Document Type and Number:
Japanese Patent JP2019165610
Kind Code:
A
Abstract:
To provide a signal control apparatus capable of appropriately performing angle feedback control, and an electric power steering apparatus using such a signal control apparatus.SOLUTION: An ECU 10, which is a signal control apparatus, includes a plurality of control units 130, 230 which control one identical motor 80. Steering angle calculation units 131, 231 acquire sensor signals from angle sensors 125, 225 provided corresponding to the steering angle calculation units, respectively, and calculate steering angles θstr1, θstr2 in correspondence to the sensor signals. Angle FB units 135, 235 perform angle FB control based on the angle differences θdiff1, θdiff2, between a target angle θtgt1 and the steering angle θstr1 and between a target angle θtgt2 and the steering angle θstr2, respectively. In the angle FB units 135, 235 of at least one of the control units 130, 230, the angle FB control is performed using the angle differences θdiff1, θdiff2 subjected to the correction processing to reduce the error between the detection angle of the own system and the detection angle of the other system calculated by the steering angle calculation unit of the other control unit.SELECTED DRAWING: Figure 4
