Abstract
A traction control system for a four-wheel steerable vehicle includes a reference value generating circuit for generating a reference value for detecting a slippage of a drive wheel in a driving state, an output torque control device for controlling the torque of the drive wheel on the basis of an output from said reference value generating circuit so as to bring said drive wheel into a predetermined slipping state, and a reference value correcting circuit for correcting the reference value on the basis of a rear wheel steering angle. This makes it possible to insure a steering stability in a critical condition when a misalignment has been produced in phases of the front and rear wheels.
