20120102940 | BRAKE APPARATUS - 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. | 05-03-2012 |
20140345272 | Master brake cylinder system and brake system for a vehicle - A master brake cylinder system having a master brake cylinder housing having at least one first pressure chamber and a second pressure chamber, a rod piston at least partially displaceable into the first pressure chamber, a floating piston situated between the first pressure chamber and second pressure chamber, and a simulator device having a simulator piston, which is at least partially displaceable into the simulator chamber counter to a spring force of at least one simulator spring present in a simulator chamber, the simulator piston of the simulator device being situated as to the second pressure chamber so that the simulator piston is displaceable at least partially into the simulator chamber, using a pressure present in the second pressure chamber against the spring force of the at least one simulator spring. In addition, also described is a brake system for a vehicle having a master brake cylinder system. | 11-27-2014 |
20150107240 | BRAKE DEVICE FOR VEHICLE - The brake device for a vehicle generates two master pressures by controlling one single servo pressure to accurately control braking force. The pressure increasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon increasing the servo pressure and the second pressure increasing characteristic obtained from the servo pressure and the second master pressure. The pressure decreasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon decreasing the servo pressure and the second pressure decreasing characteristic obtained from the servo pressure and the second master pressure. Thus, the total braking force of the brake device is the sum of a braking force generated by the first master pressure and a braking force generated by the second master piston. | 04-23-2015 |

20120073285 | BRAKE APPARATUS - A brake apparatus, which is configured to generate a hydraulic pressure in a master cylinder by driving a piston by an electric actuator, accurately and appropriately sets a control position of the piston. According to a movement of an input piston in response to an operation of a brake pedal, the brake apparatus generates a hydraulic pressure in a primary chamber of the master cylinder by driving a primary piston by an electric motor to supply brake fluid to a brake caliper, thereby exerting a brake effect. The brake apparatus sets a first control position where the primary chamber is out of communication with a reservoir, and a second control position where the primary chamber is in communication with the reservoir as a holding position of the primary piston when no brake is applied. Then, the brake apparatus can improve the brake responsiveness while preventing occurrence of a brake drag by appropriately switching the holding position of the piston between the two points. | 03-29-2012 |
20120073286 | BOOSTER - An electric booster including a plunger movable by operation of a brake pedal, an electric motor controlled based on a relative displacement between the plunger and the linear motion member, which is detected by a relative displacement sensor, and a ball and screw mechanism. The linear motion member pushes a piston of a master cylinder through a reaction member, thereby generating a brake force. Part of a reaction force from the master cylinder is fed back to the brake pedal through the reaction member. When a reference position sensor detects that a relative position of the plunger to the linear motion member coincides with a predetermined reference position, a detection value of the relative displacement sensor is stored as a relative displacement reference value, and relative displacement between the plunger and the linear motion member is determined. | 03-29-2012 |
