Abstract: 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.

Abstract: 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.

Abstract: The present invention is directed to an anti-skid control system which includes a return passage provided for communicating a wheel brake cylinder with an actuator. A pressure pump is disposed in the return passage, and a reservoir is disposed in the return passage at the inlet port's side of the pump. The reservoir stores the brake fluid in the wheel brake cylinder through the actuator to decrease the wheel cylinder pressure. The pump discharges the brake fluid stored in the reservoir into the return passage thereby to gradually increase the wheel cylinder pressure. The amount of brake fluid stored in the reservoir is estimated on the basis of the amount of brake fluid fed into the reservoir and the amount of brake fluid discharged therefrom. The amount of brake fluid fed into the reservoir is estimated on the basis of the wheel cylinder pressure provided when the pressure decreasing operation starts, and in response to the pressure decreasing time. The amount of brake fluid discharged from the reservoir is estimated on the basis of the wheel cylinder pressure set when the gradual pressure increasing operation starts, and in response to the gradual pressure increasing time.
