A new 4WD system called the 'ATTESA E-TS' has been developed based on a new approach to traction control. The E-TS system employs electronic control to achieve an optimum torque split ratio between the front and rear axles. This system is designed not only to deliver high tractive performance, but also to improve cornering performance under various road-surface friction coefficients and engine outputs. It consists of a transfer unit containing a multiplate clutch, a hydraulic unit, and a control system which is integrated with an antilock brake system and employs a wheel speed sensor at each wheel as well as a lateral acceleration sensor.
