Abstract: A vehicle brake controller is capable of executing limit control for limiting increase in braking force applied to front wheels by using a deceleration of a vehicle. The vehicle brake controller is configured to start the limit control when the deceleration of the vehicle becomes greater than or equal to a start determination value before a start determination time period elapses after a deceleration starting point in time, at which the deceleration of the vehicle is started by application of braking force at least to the front wheels. The vehicle brake controller is configured to end the limit control if the deceleration of the vehicle is less than an end determination value, which is greater than the start determination value, at a point in time when an end determination time period, which is longer than the start determination time period, has elapsed from the deceleration starting point in time.

Abstract: A vehicle hydraulic brake system of the brake-by-wire type includes input piston and a master piston configured to be actuated under hydraulic pressure introduced into a second fluid chamber and mounted in the housing so as to be movable relative to each other through a partition wall and a first fluid chamber. The piston defines therein a communication passage which extends from a fourth fluid chamber to the first fluid chamber and in which a check valve is mounted. When the piston is advanced under hydraulic pressure introduced into the second fluid chamber, the volume of the fourth fluid chamber decreases, while the volume of the first fluid chamber increases. This allows brake fluid in the fourth fluid chamber to be quickly released into the first fluid chamber through the communication passage and through a pipe line in which an electromagnetic on-off valve are mounted.

Abstract: A vehicle brake device includes a hydraulic pressure generating device, a valve device, a pump and an accumulation section forming an accumulation chamber connected to a fluid passage between the valve device and the hydraulic pressure generating device or to a master chamber. A dead band is set in which the change of force of the magnitude corresponding to the hydraulic pressure in the master chamber does not substantially act on a brake operating member. A characteristic representing the relation between the pressure and the brake fluid quantity in the accumulation chamber is set based on a characteristic representing the relation between the pressure and the brake fluid quantity in a wheel cylinder and the dead band so that, when brake fluid is flowing into and from the accumulation chamber, a force of the magnitude corresponding to the master chamber hydraulic pressure does not act on the brake operating member.

Abstract: An EPB control device controlling an electric actuator driving an EPB, wherein the device performs control to reach a lock position, a release position and a standby position between the lock position and the release position. In the lock position, a friction-applying member is thereby pressed against a friction-applied member by the EPB by actuating the electric actuator and a predetermined braking force is generated. In the release position, the friction-applying member is separated from the friction-applied member when the EPB is not actuated. In the standby position, a transition to the lock position is performed in a shorter time than when the EPB is actuated from the release position by the actuation of the electric actuator. The device controls, when a starting operation to start moving a vehicle is performed, the electric actuator such that the standby position is reached.
