    • PURPOSE:To prevent execution of redundant control due to vibration of a drive system by a method wherein an acceleration maximum value of a drive wheel during the starting of a vehicle is detected, based on the detecting value, a boosting amount of a brake pressure is computed, and boosting is continued until the boosting amount attains the computing value. CONSTITUTION:In execution of control so that a slip is prevented from occurring to the drive wheels of a vehicle, a slip occurring to the drive wheels is first detected by a means 11, and acceleration of the drive wheels is detected by a means 13. Based on detecting acceleration, a peak being the acceleration maximum value of the drive wheels during the starting of a vehicle is detected by a means 14. Based on the detecting peak, a boosting amount to increase a brake force is computed by a means 15. Consecutively, in a state in which the slip of the drive wheels and the peak are detected, a brake force is regulated by a means 12 so that a boosting output is continued until a boosting amount attains a computing value. According to a regulating brake force, the brake force of the drive wheels is controlled by a means 16.

    • PURPOSE:To speedily suppress the acceleration slip by setting the control initial value of a throttle valve after the completion of fuel cut control on the basis of the average value of the slip quantity generated on a driving wheel during the execution of fuel cut control. CONSTITUTION:When an acceleration slip detecting means M3 detects the acceleration slip of a driving wheel M2 from the signal of a speed detecting means M1, a throttle opening degree control means M7 suppresses the output torque of an internal combustion engine M4 by opening and closing a throttle valve M6, and at the same time, a fuel-cut control means M8 operates to perform fuel cut for a prescribed time, and acceleration slip control is performed. Further, a calculating means M9 calculates the average value of the slip quantity of the driving wheel M2 in the fuel cut control, and a setting means M10 sets the control initial value of the throttle opening degree after the stop of fuel cut control on the basis of the above-described average value. Thus, the opening/ closing control of the throttle valve M6 after the completion of fuel cut control is executed according to the value mu of a road surface, and the acceleration slip can be suppressed speedily.

    • PURPOSE:To carry out rationally the opening/closing control of a throttle valve in response to the frictional coefficient of a road, by setting the control initial value of a throttle opening after completion of fuel cut control, on the basis of the deceleration of driving wheels after completion of the fuel cut control. CONSTITUTION:Acceleration slip of driving wheels M2 is detected by a means M3 by including driving wheels rotating speed detected by a means M1 as one parameter. Then, the throttle valve M6 in an intake passage M5 is opened/ closed by a means M7 until the acceleration slip on the driving wheels M2 is eliminated, so that the output torque of an internal combustion engine M4 is controlled. Further, fuel supply to the internal combustion engine M4 is cut by a means M8 only for a prescribed period after starting the operation of the means M7. In such a constitution like this, after completing fuel cut, the deceleration of the driving wheels M2 is calculated by a means M9 on the basis of the driving wheels rotating speed. And the control initial value of a throttle opening is set by a means M10 after completing fuel cut.

    • PURPOSE:To prevent slip caused by shift-up by setting a closing control period of a throttle valve when a transmission is shifted from the first speed to the second speed in acceleration slip control until the shift-up is actually carried out after a shift command signal is outputted. CONSTITUTION:In the case acceleration slip is detected by means of a detecting means A according to speed of a driving wheel 16 and speed of a driven wheel 14 of a vehicle, a throttle valve opening setting means B to set time transition of opening of a throttle valve 40 is arranged so that the throttle valve 40 is closed and the slip can be canceled according to progress of acceleration. Furthermore, in the case creation of a shift-up command signal to shift from a transmission control device 18 to a transmission 12 is detected by means of a detecting means C, start-up of an actual speed change operation in the automatic transmission 12 after the shift-up command is detected by means of a detecting means D. At an interval between the creation of the shift-up command and the start-up of the speed change operation, the opening of the throttle valve is set by means of a throttle valve closed opening detecting means E in preference to a setting means B so that the opening can become smaller than the set opening by means of the setting means B.

    • PURPOSE:To carry out rationally restriction control of an output torque in response to the frictional coefficient of a road, by completing the restriction control of the output torque in an internal combustion engine, which is carried out just after generation of acceleration slip on driving wheels, when the rotating acceleration speed of the internal combustion engine decreases below a prescribed value. CONSTITUTION:Acceleration slip of driving wheels M2 is detected by a means M3 by including driving wheels rotating speed detected by a means M1 as one parameter. When a throttle valve M6 provided in an intake passage M5 is opening/closing controlled by a means M7 until the acceleration slip on the driving wheels M2 is eliminated, so that the output torque of an internal combustion engine M4 is restrained. In such a constitution like this, the rotating acceleration speed of the driving wheels M2 or the internal combustion engine M4 is detected by a means 8. An ignition timing, a fuel feed quantity and the like are controlled so as to restrain the output torque of the internal combustion engine M4 by a means 9 after operation of the means M7 is started until a detected rotating acceleration speed decreases below a prescribed value.
