초록 ▼

An anti-skid system for a motor vehicle having a driving wheel and a non-driving wheel to protect the driving wheel from skidding. The system includes a first sensor for generating a number of pulses proportional to the peripheral distance traveled by the driving wheel, a second sensor for generating a number of pulses proportional to the peripheral distance traveled by the non-driving wheel, the second sensor generating a higher number of pulses than the first sensor for the same peripheral distance traveled by the respective driving and non-driving wheels, and a unit, responsive to the signals generated by said first and second sensors, for detecting the difference in peripheral distance traveled by the driving and non-driving wheels independently of time. The detecting unit includes a circuit for producing a delay in the ignition system when the difference in peripheral distance traveled is greater than a predetermined value to adjust engine torque and to maintain optimum road adherence of the wheels.
