摘要： The present invention relates to an anti-skid brake control apparatus for a brake system of wheeled vehicles. The control apparatus according to the present invention is essentially composed of a slip speed meter, a threshold value setting device and a brake oil pressure control device. The slip speed meter calculates at least one of a slip speed and a wheel acceleration. The acceleration is a time derivative of the rotational speed of a wheel. The threshold value setting device temporarily determines a threshold value for at least one of the slip speed and the wheel acceleration with reference to at least one of the slip speed and the wheel acceleration. The brake oil pressure control device controlling braking force of the brake system with reference to at least one of a comparison of the slip speed and the threshold value thereof, and a comparison of the wheel acceleration and the threshold value thereof, whereby skidding of the wheel is prevented by temporarily controlling the braking force.

摘要： In the present invention, the conditions necessary for the change from the reducing-pressure mode to the holding pressure mode are changed based on the length of the period of instability from the beginning of wheel slippage to the stopping of this slippage, and the length of the period of continued severe locking in which the slip ratio of the wheel exceeds a certain fixed value. Therefore, even when there is a disturbance in the form of roughnesses in the road surface or the like, this is determined to be a temporary phenomenon and the switching of the setting from the reducing-pressure mode to the holding pressure mode can take place in a reliable manner, and the usual, stable braking power can be achieved in correspondence with the relationship between the road surface and the tires.

摘要： The present invention provides an electric disk brake which enables an operation for wiring the harness to be easily conducted without the risk of lowering production efficiency. A caliper body-side connector 26 which, together with a harness-side connector 24 of a harness 23, forms a connector 25, is provided in a caliper body 3. In the caliper body-side connector 26, first to fourth lead-out terminals 30a to 30d connected to an electric portion for an electric motor are arranged in this order from a first side portion 20a towards a third side portion 20c of a cover 20. In the harness-side connector 24, a first set of first to fourth harness-side terminals and a second set of first to fourth harness-side terminals independently connected to the first to fourth lead-out terminals 30a to 30d are arranged in reverse order. When an electric disk brake 1 is used for each of the left rear wheel and the right rear wheel, one of the first set of first to fourth harness-side terminals and the second set of first to fourth harness-side terminals is used for the left rear wheel while the other is used for the right rear wheel, and the first to fourth lead-out terminals and the first to fourth harness-side terminals are connected. The harnesses 23 extend in the same direction relative to the vehicle, thus ensuring ease of operation for wiring the harnesses 23.

摘要： The objective of the present invention is to present a reliable evaluation method for determining whether a moving vehicle is in a stable antiskid control operation or in an unstable antiskid control operation even when there are wheel speed pulsation caused, and a device based on such a method. In the antiskid control apparatuses and the methods of the invention, it is determined that the moving vehicle is in the stable control when the wheel acceleration being generated while the wheel speed is decreasing exceeds a predetermined threshold value, and also determined that the moving vehicle is in the unstable control when the wheel acceleration is below the threshold value. In another antiskid control apparatus and the method of the invention, it is determined that moving vehicle is in the unstable control or in the stable control basis on the changes in the wheel slipping rate with respect to the coefficient of friction between the wheel and a road.

摘要： An electric booster including a plunger movable by operation of a brake pedal, an electric motor controlled based on a relative displacement between the plunger and the linear motion member, which is detected by a relative displacement sensor, and a ball and screw mechanism. The linear motion member pushes a piston of a master cylinder through a reaction member, thereby generating a brake force. Part of a reaction force from the master cylinder is fed back to the brake pedal through the reaction member. When a reference position sensor detects that a relative position of the plunger to the linear motion member coincides with a predetermined reference position, a detection value of the relative displacement sensor is stored as a relative displacement reference value, and relative displacement between the plunger and the linear motion member is determined.

摘要： A solenoid-controlled valve has first and second valve bodies axially movably provided in a bore of a cylinder. A first spring is interposed between an end of th valve and the first valve body, a second spring is interposed between the two valve bodies, and an electromagnetic force generating device has a movable member which causes the two valve bodies to move in association with each other. Valve opening and closing modes of the two valve bodies are changed in a plurality of stages according to the displacement of the movable member. A restricting portion restricts relative displacement of the two valve. bodies away from each other so that the influence of the urging force of the second spring on the driving force of the electromagnetic force generating device becomes zero in the valve opening and closing mode in the final stage.
