SLIP CONTROLLER FOR VEHICLE

摘要

PURPOSE:To restrain a slip without unbalancing the drive torque of left and right drive wheels by giving an identical brake force to the left and right drive wheels according to an control amount or the like figured out correspondingly to the average rotational speed of the left and right drive wheels when an output control means of an engine is failured. CONSTITUTION:In a control unit UTR for controlling a slip, a slip judging means 40 for judging whether or not rear drive wheels tend to slip according to the output signals of wheel speed sensors 39a-39d for detecting the rotational speed of each wheel is provided, and in judging the slip a control amount outputted to an output controlling means consisting of a brake force controlling means 32 and throttle opening adjusting mechanism 34 for restraining the slip is obtained by a control amount calculating means 41. A failure detecting means 42 for detecting the occurrence of failures in the output controlling means is provided to output the control amount corresponding to the average value of the rotational speed of both rear wheels to the respective brake force controlling means 32 and give an identical force to both rear wheels in detecting the failure by a control condition changing means 43.
