A slip control system for vehicles having spaced apart differentially driven wheels (200,202) including means (220) for calculating wheel slip according to the ratio of wheel speeds, means (242,230,232) for entering a slip control mode wherein a braking force is applied to the slipping wheel and incrementally varied on a periodic review basis according to recalculated slip values. If slip increases or holds steady, the brake force is incrementally increased. As slip becomes less, the brake force is incrementally reduced, the particular increments of force reduction being selected in accordance with successive measurements of slip. A drive shaft signal (226) is compared to the high wheel speed signal to identify a wheel speed transducer failure.
In an anti-slip apparatus for balancing the power transfer between a pair of driven wheels (200,202) when one of the wheels loses traction and rotates faster than the other, said apparatus having first means (212,214) for braking the wheels and second means (216, 222, 220) for generating a slip signal corresponding to any difference in the rotational speeds between the wheels (200, 202), the improvement comprising:
In a system for balancing the power transfer between two differentially driven vehicle wheels (200, 202) when one of said wheels loses traction, said system being of the type which includes means (216, 222) for generating a slip signal representing the speed difference between the wheels and means (212, 214) for applying a braking force to the wheel which loses traction the improvement comprising:
A method for balancing the power transfer between two differentially driven vehicle wheels (200, 202) when one of said wheels loses traction comprising the steps of:
