摘要： A brake apparatus capable of preventing generation of an unintended brake force. The brake apparatus includes an input member configured to be moved forward and backward by an operation of a brake pedal, a stroke detector for detecting an operation stroke of the input member, and a controller for controlling an actuator based on a detection result of the stroke detector. When the controller is set into the controllable state, the controller sets a stored initial base position as a control base position of the stroke detector to control the actuator based on the detection value of the stroke detector, and each time the input member is moved backward beyond the control base position, the controller updates the control base position of the stroke detector to a position of the input member at that time.

摘要： An electric motor is controlled based on an operation of a brake pedal to move a primary piston forward through a ball screw mechanism, thereby generating a hydraulic pressure in a master cylinder. At this time, a reaction force from the hydraulic pressure in the master cylinder is fed back to the brake pedal through an input piston. Automatic brake control, which generates the hydraulic pressure by driving the electric motor regardless of whether there is the operation of the brake pedal, is carried out. During the automatic brake control, an actual relative position is compared with a determination threshold value set based on the relative position between the primary piston and the input piston which is generated by a movement of the primary piston, and it is determined that the brake pedal is operated in a case where the relative position is smaller than the determination threshold value.

摘要： A brake control system displaces a primary piston by controlling an operation of the electric motor by a master pressure control unit according to the operation amount (Xop) of the brake pedal, thereby generating a hydraulic pressure in the master cylinder to supply it to wheel cylinders (Ba to Bd). The master pressure control unit sets a target relative displacement (ΔXT) between an input piston and the primary piston and a target hydraulic pressure (PT) in the master cylinder, and appropriately switch which is used to control a brake force. During regenerative cooperation, the master pressure control unit selects the control with use of the target hydraulic pressure, which enables easy execution of a hydraulic pressure control including a subtraction of the hydraulic pressure corresponding to a brake effect from the regenerative cooperation.
