摘要： A traction control method for a vehicle, comprising the steps of: judging an excessive slipping state of a plurality of driving wheels by taking into account, as at least one judgment requirement, whether or not a driving-wheel speed exceeds a braking-force controlling target wheel speed determined by taking into account a predetermined slip rate of a vehicle speed, and controlling a braking force for the driving wheels in accordance with the result of the judgment, wherein the intensity of a slipping tendency for every one of the driving wheels is determined on the basis of a judgment value which is set larger than the vehicle speed and smaller than the braking-force controlling target wheel speed, and the smaller the number of the driving wheels determined to have a large slipping tendency, the more the braking-force controlling target wheel speed is increased. This prevents the occurrence of an excessive control of braking force, when the slipping tendency of only a part of the driving wheels is large.

摘要： A pressure source for a pressure device includes a pump for pumping fluid from fluid tank, an accumulator connected to the pump and a pressure device, a device for detecting the pressure in the accumulator, and a controller for controlling the operation of the pump in an ON-OFF manner on the basis of a result of detection by the pressure detecting device. In this pressure source, the controller includes first and second drive signal generating circuits each capable of independently generating a drive signal for determining the on-off operation of the pump, and a judging circuit which has a calculating function therein and to which at least the pressure detecting device is connected. The judging circuit is connected to the first drive signal generating circuit, and the pressure detecting device is connected to the second drive signal generating circuit. This ensures that the control of the first drive signal generating circuit can be carried out at any time by a calculation in the judging circuit, leading to an increased function. When the judging circuit is in trouble, the on-off control of the pump can be carried out by the second drive signal generating circuit.

摘要： A signal value on the basis of a lower wheel speed is compared with a signal value on the basis of a high wheel speed and, when the difference therebetween is larger than a predetermined value, a higher vehicle speed of two previously estimated vehicle speeds is used for anti-lock control and a reference value with which a wheel speed will be compared is derived from such vehicle speed. Thus, a range of condition for judging that wheels of a vehicle are about to be locked is enlarged.
