Abstract
When a normal braking is performed, a master cylinder ( ) and wheel cylinders ( FR, FL, RR, RL) are set to a conducting state. When an emergency braking is performed, the master cylinder and the wheel cylinders are joined together so that a large brake force can be generated. If the wheel cylinders are connected to an accumulator soon after the emergency braking, an increase in the wheel cylinder pressure can be prevented. Even after the emergency braking, the wheel cylinders and the master cylinder are maintained in the conducting state while the master cylinder pressure is rapidly increasing.
