Abstract:
1. An electronically controlled hydraulic brake system, comprising: a pressure increasing pump which increases a brake hydraulic pressure in a brake hydraulic line; a motor connected to the pressure increasing pump, the motor being controlled on the basis of a motor drive current command value to bring the brake hydraulic pressure to a target brake hydraulic pressure; a pressure detector which detects an actual hydraulic pressure in the brake hydraulic line; and a controller connected to the motor and the pressure detector, the controller being arranged to calculate an attainment brake hydraulic pressure, which is a maximum brake hydraulic pressure attained when the motor operates in response to the motor drive current command value, to obtain a linear compensation executed attainment brake hydraulic pressure by linearly compensating the attainment brake hydraulic pressure using the actual brake hydraulic pressure, to obtain a linear compensation executed motor drive current command value by executing an inverse calculation of a calculation for obtaining the linear compensation executed attainment brake hydraulic pressure, and to control the motor based on the linear compensation executed motor drive current command value.
