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： 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： The present invention is directed to an anti-skid control system for controlling a braking force applied to road wheels including driven wheels of an electrically operated vehicle which has an electrical motor for driving the driven wheels. A hydraulic braking pressure is supplied to each wheel brake cylinder through an actuator. The actuator is controlled by a braking force controller into which output signals of wheel speed sensors are fed. A band-pass filter is provided for passing the wheel speeds of the driven wheels having an oscillation property within a predetermined band of frequencies, out of the wheel speeds detected by the wheel speed sensors. And, a coefficient of friction of a road is estimated to be relatively low when the output of the band-pass filter is in a predetermined range of frequencies. The hydraulic braking pressure in each wheel brake cylinder is controlled by the braking force controller in accordance with the estimated coefficient of friction and in response to the wheel speeds detected by the wheel speed sensors, thereby to control the braking force applied to each road wheel.

摘要： A brake hydraulic pressure generator is proposed which is simple in structure and can suppress fluctuations in the brake pedal operating amount due to fluctuations in the amount of brake fluid consumed in the brake circuit. The brake hydraulic pressure generator includes an input shaft operated by a brake pedal, a stroke simulator for imparting a stroke and a reaction force corresponding to the brake pedal operating amount to the input shaft, a master cylinder for generating brake hydraulic pressure, and a pressure detector member for applying a reaction force corresponding to the hydraulic pressure in the master cylinder to a valve member of the control valve. The reaction force is transmitted through the pressure detector member to the control member. The input to the brake pedal is transmitted to the control valve through the stroke simulator so as to oppose the reaction force. The control valve operates to balance the reaction force and the input.

摘要： A hydraulic brake apparatus for a vehicle includes a supplementary hydraulic pressure source outputting a pressurized output hydraulic pressure and an electronic control apparatus that controls a hydraulic pump in the supplementary hydraulic pressure source. The electronic control apparatus judges whether the hydraulic pump satisfies a predetermined operating condition based on the output hydraulic pressure of the supplementary hydraulic pressure source or not. The electronic control apparatus compares the output hydraulic pressure with a minimum standard hydraulic pressure, detects a drop in the output hydraulic pressure when the output hydraulic pressure is less than a standard hydraulic pressure and determines that the hydraulic pump does not satisfy the predetermined operating condition.

摘要： A throttle control apparatus for use with an automotive internal combustion engine. The apparatus assures that the drive wheels are stopped from spinning on a snowy road surface if the driver pushes down on the accelerator pedal. The apparatus comprises an accelerator operation mechanism including the accelerator pedal, a first throttle-driving means capable of opening and closing the throttle valve, a controller, a second driving means, and a fuel-cutting means. The first throttle-driving means is mounted independent of the accelerator operation mechanism and includes a driving plate, a clutch plate, and a movable yoke. The controller controls the first throttle-driving means to adjust the throttle opening. When the first throttle-driving means becomes inoperative, the throttle valve can be driven by the accelerator operation mechanism via the second throttle-driving means. The fuel-cutting means is operated when excessive spin of the drive wheels is detected.
