Patent ID: 7241249

Claim:
A driving condition control system installed in a vehicle, wherein said vehicle has a source of power for generating power, a first rotatable axle assembly to which a first wheel is attached, and a second rotatable axle assembly to which a second wheel is attached, said power being transferred to the second rotatable axle assembly so that the second rotatable axle assembly is rotated to generate torque, said driving condition control system comprising: a sensing unit configured to sense a first physical quantity indicative of a rotation of the first rotatable axle assembly and a second physical quantity indicative of a rotation of the second rotatable axle assembly; and a correcting unit configured to correct the torque according to a ratio between the sensed first and second physical quantities of the rotations of the first and second rotational axle assemblies, wherein said correcting unit is configured to sequentially correct a value of the torque using the following equation: Td -new=min{( Vr/Vd ), 1}· Td -now, where Vr represents the sensed first physical quantity, Vd represents the sensed second physical quantity, Td-new represents a value of the corrected torque, Td-now represents a previous value of the torque previously corrected by the correcting unit, and min{(Vr/Vd), 1} represents a function of outputting the lesser of the (Vr/Vd) and 1.
