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.

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 to compensate for lack of the regenerative braking torque, when voltage of a battery exceeds an upper limit. 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 supplying pressurized brake fluid to a wheel brake cylinder in response to operation of a manually operated braking member to apply the hydraulic braking force to the wheel. A reducing device is provided for reducing the regenerative braking torque when the voltage of the battery exceeds a predetermined upper limit. And, a compensation device is provided for actuating the pressure control device to supply the pressurized brake fluid to the wheel brake cylinder when the regenerative braking torque reduced by the reducing device exceeds a predetermined level, e.g., when a rate for reducing the regenerative braking torque exceeds a predetermined rate, or when a reduced amount of the regenerative braking torque exceeds a predetermined amount.

摘要： The present invention is directed to a brake control system for an electrically operated vehicle which is adapted to add a hydraulic braking operation to a regenerative braking operation, or change the former for the latter, rapidly and smoothly. An electric motor is operatively connected to a wheel for rotating the wheel, and a motor control unit for controlling the electric motor to apply a rotating force and a regenerative braking force to the wheel. In a main passage for connecting a master cylinder with a wheel brake cylinder, a pressure limit changeover device is disposed. The changeover device includes a first pressure limit device which is adapted to close the main passage when a master cylinder pressure is lower than a first predetermined pressure, and open the main passage when the master cylinder pressure exceeds the first predetermined pressure, and a second pressure limit device which is adapted to close the main passage when the master cylinder pressure is lower than a second predetermined pressure which is lower than the first predetermined pressure, and open the main passage when the master cylinder pressure exceeds the second predetermined pressure. First and second valve devices for opening or closing the main passage are connected to the main passage in parallel with the first pressure limit device, and the second valve device is connected in series of the second pressure limit device.
