摘要： A driving wheel slip control system installed in a vehicle and having abnormality-detecting and failsafe functions. The system includes a slip status signal-generating device for generating a slip status signal indicative of whether or not the driving wheels of the vehicle are in a predetermined slip state, and a slip level signal-generating device for generating a slip level signal indicative of a degree of slip of the driving wheels. If a logical relationship between the slip status signal and the slip level signal is abnormal, and if the prime mover for driving the driving wheels is not accelerating and at the same time the slip level signal indicates the predetermined slip state, the slip level signal is determined to be abnormal. If an abnormality is detected during driving wheel slip control, an amount of reduction in output of the driving wheels is set to a predetermined amount to thereby continue driving wheel slip control, until the prime mover enters an operating condition other than acceleration. Further, the system comprises first and second control units. The latter informs the former of three states for determining whether or not driving wheel slip control can be carried out. The first control unit has the slip level signal-generating device and the slip status signal-generating device, and inhibition of operation of these devices is retarded when it is informed of a state inhibiting driving wheel slip control, if an excessive slip state of the driving wheels is occurring.
