Class Information
Number: 180/197
Name: Motor vehicles > With means for detecting wheel slip during vehicle acceleration and controlling it by reducing application of power to wheel
Description: Apparatus wherein the vehicle is provided with means for determining if a driven wheel is rotating more rapidly than is proportional to the speed of the vehicle (i.e., the wheel is spinning relative to the surface with which it is in engagement) during a period when the speed of the vehicle is being increased, and for taking action to reduce or eliminate the unproportionality of the rotational velocity of the wheel to the speed of the vehicle by decreasing the amount or the effect of the power being applied to drive the wheel.
