摘要： An object of the present invention is to provide an electric disc brake apparatus having a simple constitution in which the operating condition of a parking brake can be reliably detected. A controller detects the operating condition (steps S25, S26) of a solenoid for driving a parking brake locking mechanism (holding mechanism) by means of a motor current (step S24). As a result, a state in which thrust generated by the motor (first electric actuator) is maintained by the parking brake locking mechanism, and accordingly the operative and inoperative states of the parking brake can be understood easily. Further, detection of the motor current is performed using a current sensor that is also used to realize a function of the motor (a function for moving brake pads toward a disc rotor), and hence separate current detection means need not be provided. Accordingly, the operative or inoperative state of the parking brake can be understood by means of a simple constitution, enabling a reduction in the cost of the apparatus.
摘要翻译：本发明的目的是提供一种电动盘式制动装置，其具有可以可靠地检测到驻车制动器的运行状态的简单结构。控制器通过电动机电流检测用于驱动驻车制动器锁定机构（保持机构）的螺线管的操作状态（步骤S25，S26）（步骤S24）。结果，可以容易地理解由驻车制动器锁定机构保持由电动机（第一电动致动器）产生的推力的状态，并且因此可以容易地理解驻车制动器的工作状态和不工作状态。此外，使用也用于实现电动机的功能的电流传感器（用于将制动衬块朝向盘形转子移动的功能）进行电动机电流的检测，因此不需要设置分离的电流检测装置。因此，可以通过简单的结构来理解驻车制动器的操作或非操作状态，从而能够降低装置的成本。

摘要： A brake system is provided with a brake pressure control device which is light in weight and low in cost and which is capable of selectively performing a brake assist control and a slope starting control. An electromagnetic pressure control valve for generating a control differential pressure is connected between a master cylinder and wheel cylinders, and the control differential pressure is set to an assist increase pressure under the brake assist control. A brake fluid supply device such as a motor-driven pump is operated in the brake pressure control device to supply brake fluid between the electromagnetic pressure control valve and each of the wheel cylinders. The fluid pressure applied to the wheel cylinders is increased by the assist increase pressure than the fluid pressure delivered from the master cylinder, so that a large brake force is applied to road wheels. On the other hand, the brake fluid supply device is also operated under the brake assist control. Thus, even when the release of a brake pedal causes the master cylinder to deliver the fluid of zero-pressure, the stop holding pressure remains closed in each wheel cylinder, so that the road wheels are kept stopped with the brake forces applied thereon.
摘要翻译：制动系统配备有重量轻，成本低的制动压力控制装置，能够选择性地进行制动辅助控制和斜坡起动控制。在主缸和轮缸之间连接有用于产生控制压差的电磁压力控制阀，并且在制动辅助控制下将控制差压设定为辅助增压。在制动压力控制装置中操作诸如电动泵的制动液供给装置，以在电磁压力控制阀和每个轮缸之间提供制动流体。施加到轮缸的流体压力通过辅助增加压力而增加，而不是从主缸输送的流体压力，使得大的制动力施加到车轮上。另一方面，制动液供给装置也在制动辅助控制下进行动作。因此，即使当制动踏板的释放使主缸传递零压力的流体时，每个轮缸中的停止保持压力保持关闭，使得在施加制动力的情况下使车轮保持停止。

摘要： An electro-hydraulic braking system of the type which operates normally in a brake-by-wire mode wherein hydraulic pressure is applied to braking devices at the vehicle wheels in proportion to the driver's braking demand as sensed electronically at a brake pedal (10), and which, if the brake-by-wire mode should fail, operates in a push-through mode wherein hydraulic pressure is applied to the braking devices at the vehicle wheels by way of a master cylinder (34) coupled mechanically to the brake pedal (10), the system including also an electric parking braking means for enabling the braking devices to be actuated for parking braking purposes but which is also arranged to be activated to supplement push-through braking in the event of failure of the brake-by-wire mode. Electro-hydraulic braking at the rear axle of the vehicle is allowed only when a control unit (13) of the electro-hydraulic braking system has confirmation that the electric parking means is in a satisfactory operational state.

摘要： In a vehicle hydraulic brake device, the hydraulic pressure supplied from a hydraulic pressure source is adjusted to a value proportional to the brake operating amount by a pressure adjusting valve, and a master cylinder is actuated under the output hydraulic pressure of the pressure adjusting valve introduced into a pressure chamber to produce braking force. The output hydraulic pressure of the pressure adjusting valve and that of the master cylinder are detected with a pressure sensor and a master cylinder pressure sensor and compared with a bottoming detector. If the output hydraulic pressure of the master cylinder does not meet a predetermined relation, and the bottoming detector determines that bottoming has occurred, and the output hydraulic pressure of the master cylinder at this time is not less than a predetermined first hydraulic pressure, a solenoid valve provided between the pressure adjusting valve and the master cylinder is opened, and a solenoid valve provided between the master cylinder and an atmospheric reservoir is closed to supply the output hydraulic pressure of the pressure adjusting valve to two of the four wheel cylinders through the master cylinder.

摘要： When a vehicle is suddenly stopped by turning off an ignition key switch on a way of a slope road, a braking force maintaining control is not preformed, and it often occurs that the vehicle moves down along the slope road. To prevent such occurrence, an electro-mechanical braking device for maintaining the braking force is provided so that the vehicle is parked securely. The electro-mechanical braking device includes a parking brake mechanism for maintaining the brake force even when an ignition key switch (power supply switch) of the vehicle is turned off. When the power supply switch (ignition key switch) of the vehicle is turned off with a braking pedal being stroked or a braking operation signal being present, the parking-brake mechanism is activated (the brake force is maintained).

摘要： An anti-lock brake system for a tri-axle wheeled vehicle equipped with wheel speed sensors and modulators for adjusting brake pressure. The modulators are actuated by a six-channel electronic control unit. The modulators associated with the front axle of the vehicle are individually actuated. The modulators associated with the two rear axles of the vehicle are side-by-side or axle modulators, each actuated jointly by respective end stages of the six channels. The electronic control unit detects whether the anti-lock brake system in which it is installed is a compatible anti-lock brake system. An error signal indicating improper installation is delivered.

摘要： A brake control system and method controls a braking operation in a vehicle. When a pressure sensor and a stroke sensor are functioning normally, a brake control system calculates a final target deceleration Gt as a weighted sum of a target deceleration Gpt that is based on a master cylinder pressure Pm and a target deceleration Gst that is based on a depression stroke St, and a braking force is controlled based on the final target deceleration Gt. On the other hand, when there is an abnormality in the stroke sensor, the brake control system calculates a target deceleration Gpt that is greater than when the stroke sensor is functioning normally in a region where the braking amount is small, and the target deceleration Gpt is set to the final target deceleration Gt. When there is an abnormality in the pressure sensor, the brake control system calculates a target deceleration Gst that is larger than when the pressure sensor is functioning normally in a range where the braking amount is large, and the target deceleration Gst is set to the final target deceleration Gt.
