Abstract
In order to achieve a good brake feeling, a brake control system includes a master cylinder which discharges pressurized operating fluid according to an operating amount of a brake operating member by a driver, a stroke simulator which is connected to the master cylinder and creates a reaction force with respect to that operation according to the operating amount of the brake operating member, and a control portion which calculates a target deceleration using hydraulic pressure in the stroke simulator. The brake control system is also provided with a master cylinder pressure sensor that measures the hydraulic pressure in the master cylinder. The control portion may also calculate the target deceleration using an estimated value of the hydraulic pressure in the stroke simulator calculated based on the measured value from the master cylinder pressure sensor.
