摘要： A master cylinder includes pressurizing chambers and atmospheric pressure chambers which are in communication with a reservoir provided upstream. The pressurizing chambers of the master cylinder are connected to a brake fluid pressure control valve device through master pressure pipes provided with master cut valves. The atmospheric pressure chambers of the master cylinder bypass the master cut valves and are connected to the brake fluid pressure control valve device through bypass pipes provided with check valves. A pump constituting a brake fluid pressurizing section of the brake hydraulic control valve device suctions the brake fluid from the reservoir preferentially through the bypass pipes provided with the check valves and pressurizes the brake fluid to supply a brake fluid pressure to brake fluid pressure adjust sections.

摘要： A first ECU estimates whether the operation of a second actuator has been started, based on the variation of the hydraulic pressure with respect to the flow rate of hydraulic fluid outputted from a first actuator. Even in a case where the operation information of the second actuator is not received, the first ECU sets the control mode to a simultaneous operation mode, when it is estimated that the operation of the second actuator has been started. In the simultaneous operation mode, a controlled parameter of linear control valves on assumption that the second actuator is operating is set up, and a stop instruction of regenerative braking is transmitted to a hybrid ECU.

摘要： A hydraulic brake system includes a first actuator for a regeneration coordination brake control and a second actuator for maintaining the stability of a vehicle in a hydraulic pressure passage between a master cylinder and a wheel cylinder. The first actuator is controlled by a first ECU, and the second actuator is controlled by a second ECU. When a failure occurs in the first actuator or the first ECU, the second ECU operates the second actuator according to the amount of a brake operation, and assists braking of a wheel.

摘要： A hydraulic brake system, including: a brake operation member; a brake device; a master cylinder; a communication switching valve; a low-pressure-source shut-off valve; a high-pressure source; a regulator; a pressure adjuster; and a controller, wherein, when a pressurizing state of the master cylinder is switched from a first pressurizing state to a second pressurizing state after initiation of an operation on the brake operation member, the controller executes a pressurizing-state switching control in which switching of a state of the low-pressure-source shut-off valve from an open state to a closed state and switching of a state of the communication switching valve from a closed state to an open state are carried out after a pressure-regulating state of the regulator has been switched from a first pressure-regulating state to a second pressure-regulating state by controlling the pressure adjuster to increase a second pilot pressure while the first pressurizing state is maintained.

摘要： An electric-brake controller includes an antilock controller configured to control a pressing force of an electric brake. The electric brake includes a pressing member that is advanced by rotation of an electric motor in a forward direction to press a friction member against a brake rotation member. The electric brake includes a return spring that applies a spring force such that the pressing member is moved away from the brake rotation member. The antilock controller includes a pressing-force reducer that reduces the pressing force. The pressing-force reducer includes: a reverse-rotation-current supplier that supplies reverse-rotation current for rotating the electric motor in a reverse direction for a reverse-rotation-current supply time; and a forward-rotation-current supplier that supplies forward-rotation current, for rotating the electric motor in the forward direction, to the electric motor after the reverse-rotation current is supplied for the reverse-rotation-current supply time.

摘要： A current whose magnitude corresponds to first pressing force-current characteristics set to prevent forward movement of a driven member from being stopped is applied to a motor when the driven member moves forward, and a current whose magnitude corresponds to second pressing force-current characteristics set to move the stopped driven member forward is applied to the motor when the driven member is stopped, in the case where a relationship between a pressing force as a force with which a friction member presses a rotating body and an energization current to the motor is defined as pressing force-current characteristics.
