摘要： A method and apparatus for controlling brakes using a reciprocating cut valve actuated by an expander piston that is moved via a crank pin on a crank shaft. The cut valve cuts off caliper pressure and adjusts the volume and pressure of an output hydraulic chamber to effectuate antilock braking. When changing from antilock braking to normal braking, the movement of the expander piston is controlled by repeatedly changing a crank angle of the crank pin during specified time intervals. The rate of increase in caliper pressure can be set according to (1) detected brake operation which is detected from a present crank angle and a target crank angle and (2) the frictional state of the road surface which is estimated from vehicle acceleration/deceleration.

摘要： A device for controlling the braking force of a motorcycle in two controlling modes: a normal mode and an antilocking mode, comprises tachometers mounted on front and rear wheels of the motorcycle, an accelerometer mounted on the motorcycle body, and a control circuit. The control circuit calculates a peripheral acceleration of each wheel based on the peripheral velocity of each wheel, and a slippage ratio of each wheel based on the peripheral velocity of the wheel and the acceleration of the motorcycle body. When the slippage ratio and the peripheral acceleration of one wheel meets given conditions, the control circuit starts, prior to entering into the antilocking mode from the normal mode, to calculate the coefficient of friction between the road surface and the one wheel. For the other wheel, the coefficient of friction is calculated in the same manner.

摘要： The ABS is provided with a modulator, and when the ABS is activated, control of the caliper pressure by the driver, is modified by the operation of the modulator having the aforementioned inlet valve (normally closed to a pressurized fluid source) and aforementioned outlet valve (normally open to a fluid exit), both controlled by the above-described control logic circuit. The modulator increases or decreases the caliper pressure, in response to changes in the pressurized fluid, regulated by such valves. Depending on the operation of the control logic circuit described above, three events may occur. When the inlet and outlet valves are not operated (i.e. their normal state), the modulator releases pressurized fluid through the output valve, and increases caliper pressure, to increase braking up to a predetermined maximum. If only the outlet valve is operated (i.e. both the inlet and outlet valves are closed), the modulator remains in a constant state and likewise, the caliper pressure is kept constant. If both the inlet and outlet valves are operated (i.e. opened and closed respectively), then in response to the increased pressurized fluid, the modulator effects a decrease in caliper pressure to reduce braking. The above is summarized in FIG. 2.Thus it is seen that the brake control is effected by setting a threshold value for each of the slip ratio .lambda. and the acceleration/deceleration .alpha., and determining whether the actual state of each wheel (i.e. .lambda.and .alpha.), is at their respective threshold value or above (less). It is thus necessary to set processing times as short as possible to improve the operating speed of an actuator which executes the process referred to above. However, there are limitations on the operating speed of the actuator, and an improvement is actually difficult to achieve.In another prior art system, the modulator comprises an input hydraulic chamber which communicates with a master cylinder, for

摘要： A brake control system for obtaining the optimal slippage ratio for stable braking of a vehicle, has a friction coefficient detecting device, a target slippage ratio setting device, a correction coefficient setting device and a target slippage ratio correcting device. The friction coefficient detecting device detects the coefficient of friction between each of wheels and a road surface. The target slippage ratio setting device sets up a target slippage ratio based on the coefficient of friction. The correction coefficient setting device detects the rate of change in the coefficient of friction and sets a first correction coefficient for calculating the target slippage ratio based on the rate of change in the coefficient of friction. The target slippage ratio correcting device multiplies the target slippage ratio by the first correction coefficient thereby to correct the target slippage ratio. Thus, the vehicle can be smoothly driven.

摘要： A method of and an apparatus for estimating a vehicle velocity, which are suitable for use in a vehicle. Velocities of drive wheels and follower wheels of the vehicle are determined and the fastest one of the so-determined velocities is selected. The velocity of the vehicle is estimated based on the fastest wheel velocity thus selected. The above respective processes are repeatedly executed at given time intervals. Thus, when the estimated vehicle velocity is faster than each of the velocities of the follower wheels and lower than the fastest wheel velocity, the estimated vehicle velocity determined immediately before the above estimating process is set as a desired estimated vehicle velocity. Accordingly, a high-accuracy estimated vehicle velocity corresponding to an actual vehicle velocity can be obtained, thereby making it possible to control brakes and driving forces with high accuracy using the estimated vehicle velocity.
