Abstract: 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.

Abstract: 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.

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.
