Title:
BRAKE CONTROL DEVICE AND BRAKE SYSTEM
Document Type and Number:
Japanese Patent JP2017178091
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To drive efficiently an electric motor.SOLUTION: An brake control device (an electronic control device 2A) is used in a brake system that controls a brake by generating brake fluid pressure by driving force of an electric motor 30. The brake control device comprises: an electric angle acquiring portion 130 that acquires an electric angle of the electric motor 30; a driving amount calculating portion 140 that calculates a control instruction value which is outputted to the electric motor 30 by the electric angle; and an output portion 150 that outputs power to the electric motor 30 on the basis of the calculated control instruction value by the driving amount calculating portion 140. The driving amount calculating portion 140 has a correction amount calculating portion 141 that calculates correction amounts corresponding to rotation of the electric motor 30 for a period of time from when the electric angle acquiring portion 130 acquires the electric angle until when the output portion renews power and outputs the power, and corrects an electric angle at the time of calculating the control instruction value using the correction amounts.SELECTED DRAWING: Figure 3
