  • Patent number: 9707945
    Abstract: A brake system includes a master cylinder, a first solenoid valve, a stroke simulator, a slave cylinder apparatus, and a control apparatus. The master cylinder generates a brake hydraulic pressure in response to an operation on a brake operator. The first solenoid valve is provided between the master cylinder and a wheel brake. The stroke simulator is connected to the master cylinder through a second solenoid valve. The slave cylinder apparatus includes an electric actuator and a cylinder mechanism. The cylinder mechanism generates a brake hydraulic pressure. The control apparatus closes the first solenoid valve and opens the second solenoid valve when the brake hydraulic pressure is increased by the electric actuator. The control apparatus controls the electric actuator so that the larger a carried load on a vehicle is, the larger the brake hydraulic pressure is.
