車両用制動装置
Document Type and Number:
Japanese Patent JP7424165
Kind Code:
B2
Abstract:
A vehicle braking device includes a first pressurizing unit including a cylinder, a piston slidable in the cylinder, an electric motor that drives the piston, and an output chamber partitioned by the cylinder and the piston. The first pressurizing unit is configured such that a connection state between the output chamber and a reservoir is switched between communication and cut-off states according to the piston position, and the first pressurizing unit is capable of pressurizing fluid by decreasing a volume of the output chamber by movement of the piston to one axial direction side; a pressure sensor that detects a pressure of the output chamber; and an estimation unit that executes a position estimation process of moving the piston and estimating a switching position of the piston at which the connection state of the output chamber and the reservoir is switched based on a detection value of the pressure sensor.
