Electric brake system, hydraulic control circuit and fluid control circuit

摘要

It provides an electric brake system, a hydraulic pressure control circuit, and a liquid amount control circuit capable of improving the control precision of the wheel cylinder pressure by the liquid supply device. The electric brake system includes a hydraulic pressure control circuit that controls driving of an electric actuator so that a target hydraulic pressure corresponding to a brake command is generated in the master cylinder by acquiring a detected value from a hydraulic pressure detection unit that detects hydraulic pressure in a master cylinder, and a master cylinder and wheel. A liquid amount control circuit for controlling a liquid amount supplied to the wheel cylinder by driving a liquid amount supply device disposed between the cylinders, and a storage circuit for storing liquid amount characteristics, which are characteristics of the liquid amount with respect to a detected value, are provided. The liquid amount control circuit controls the liquid amount supply device based on the liquid amount characteristic stored in the memory circuit.
