摘要： PURPOSE:To prevent the free running state generated at the control shifting time on the crossover road surface or the like by computing the controlled variable on the basis of the wheel speed excluding higher driving wheel speed during the traction control time of a vehicle so as to perform the anti-skid control of the vehicle. CONSTITUTION:Each wheel speed of a vehicle is detected by a means A. Traction control is performed by a means B to suppress the acceleration slip of each wheel on the basis of the detected wheel speed. Anti-skid control is also performed by a means C to suppress the locking of each wheel. In the means C in this case, a means D discriminates whether or not the means B is in control operation. The controlled variable is computed by a means E on the basis of each detected wheel speed at the non controlling time of the means B as well as on the basis of the wheel speed excluding at least the higher driving wheel speed at the controlling time of the means B. The braking pressure of each wheel is then controlled by a means F according to the computed controlled variable.

摘要： PURPOSE:To make it possible to carry out the precise control of antiskid, and as well to obtain the interchangeability of antiskid devices, by compensating deviations in the speed of vehicle rear wheels. CONSTITUTION:When a vehicle runs straightforward at a constant speed more than a predetermined speed within predetermined acceleration and deceleration in the condition of no braking, a compensating factor for the speed of rear wheels is calculated in accordance with the speeds of wheels 29, 30 detected by sensors 1 through 3. Further, the detected rear wheel speed is compensated by multiplying the rear wheel speed with a factor which is obtained by integrating and averaging the compensating factors. Thus, the detected rear wheel speed is compensated by the compensating factor which is automatically calculated so that precise speed data are obtained, thereby precise brake control is carried out.

摘要： PURPOSE:To prevent a control distance from being extended by miscontrol due to the abnormality of a microcomputer by inhibiting the looseness control of brake pressure at the time of detecting abnormality in the arithmetic processing of the microcomputer. CONSTITUTION:Prior to the execution of a control program, a microcomputer 2 judges whether the operation of a runaway detection circuit 6 is normal or not, and only when the operation is normal, starts the execution of the control program. When the abnormality of the microcomputer 2 is detected at the time of executing the control program, the microcomputer 2 is reset by means of the circuit 6 and the looseness control of the brake is inhibited until a reset pulse signal is inputted from the circuit 6 to the microcomputer 2. Consequently a control distance can be prevented from being extended by miscontrol due to the abnormality of the microcomputer 2.
