摘要： A pressure generating apparatus for a hydraulic brake system, including a master cylinder having a pressure piston which partially defines a pressure chamber and which is advanced to generate a fluid pressure in the pressure chamber in response to an operation of a brake operating member. The apparatus further includes inhibiting device having a non-operated state for allowing the pressure piston to be advanced, and an operated state for inhibiting the pressure piston from being advanced, and a pressure changing device having a pressure changing chamber communicating with the pressure chamber. The pressure changing device operates to change a volume of the pressure changing chamber and thereby change the pressure chamber pressure. A controller is provided for controlling the inhibiting device and the pressure changing device, to change the pressure in the pressure chamber while the inhibiting device is placed in the operated state.

摘要： A brake controlling apparatus in an electric vehicle comprising a hydraulic brake including a fluid pressure generating and applying device having a characteristic in which the fluid consumption rises in the fluid-pressure range of 0 to P.sub.0, and brakes the driving wheels by the fluid pressure of the fluid pressure applying device. A regenerative brake brakes the driving wheels by the regeneration of the power of a driving motor. A fluid flow cut-off device cuts off the flow of hydraulic fluid from the fluid pressure generating device to the fluid pressure applying device when the fluid pressure of the fluid pressure generating device exceeds P.sub.0. A fluid flow inducing device induces the flow of hydraulic fluid from the fluid pressure generating device to the fluid pressure applying device while maintaining the pressure difference between the fluid pressure generating and applying devices when the pressure difference exceeds .DELTA.P.sub.r. A fluid consuming device consumes the hydraulic fluid of the fluid pressure generating device with the characteristic approximate to the fluid consumption characteristic of the fluid pressure applying device when the fluid flow inducing device is inoperative. A regenerative braking controlling device controls the regenerative brake in correspondence with the pressure difference between the fluid pressure generating device and the fluid pressure applying device. The fluid consumption characteristic seen from the fluid pressure generating device is substantially the same as the fluid consumption characteristic of the fluid pressure applying device.

摘要： In an electrically operated vehicle in which a regenerative braking operation is performed to apply a regenerative braking torque to a wheel, if the regenerative braking torque reaches its maximum value and is insufficient to brake the wheel, a static hydraulic pressure outputted from a master cylinder is supplied to the wheel brake cylinder mounted on the wheel until the brake pedal reaches a retained position. Thereafter, a dynamic hydraulic pressure is supplied to the wheel brake cylinder. While the brake pedal is in movement from the rest position to the retained position, the wheel brake cylinder is supplied with only the static hydraulic pressure and while the brake pedal is being retained at the retained position the wheel brake cylinder is supplied with the static hydraulic pressure and the dynamic hydraulic pressure.

摘要： A brake control system mounted in an electrical vehicle for controlling a hydraulic brake and a regenerative brake. The hydraulic brake generates a hydraulic pressure depending on an amount of depression of a brake pedal so as to mechanically brake at least drive wheels. The regenerative brake brakes the drive wheels due to a regeneration of a running motor. A reducing valve is provided in a hydraulic pressure transmission path to the drive wheels to be braked by the hydraulic brake. The reducing valve is opened when the hydraulic pressure genrated in a cylinder is at least a valve open value to allow a hydraulic pressure transmission to drive wheel pipings. An ECU calculates a regenerative torque command value depending on a pressure difference between the front and rear of the reducing valve, detected by a sensor, and controls the regenerative brake on the basis of the regenerative torque command value. In turn, a liquid amount corresponding to the hydraulic pressure cut off by the reducing valve is consumed with a similar characteristic to the hydraulic brake by a stroke simulator.

摘要： The present invention is directed to a brake control system for an electrically operated vehicle, which is adapted to reduce a regenerative braking torque and add a hydraulic braking force. A motor control unit is provided for controlling an electric motor to apply a rotating force to a wheel and apply the regenerative braking torque to the wheel. A pressure control device is provided for controlling a hydraulic braking pressure generated by a pressure generator in response to operation of a manually operated braking member, and supplied to a wheel brake cylinder, which is operatively mounted on the wheel for applying a hydraulic braking force to the wheel. The regenerative braking torque is reduced in response to a braking condition monitored by a monitor. A pressure difference is detected between the hydraulic braking pressure of the brake fluid discharged from the pressure generator and the hydraulic braking pressure in the wheel brake cylinder. And, a characteristic of the regenerative braking torque to be reduced is modified in response to the pressure difference, to compensate for lack of regenerative braking torque by the hydraulic braking force, smoothly.
