Control system for limited-slip differential gear unit associated with wheel-spinning preventive traction control system

A combination comprising:

• a traction control system for monitoring a vehicular driving condition indicative of vehicular wheel slippage based on preselected control parameters and being responsive to wheel slippage for adjusting driving torque to driven wheels depending upon a magnitude of said wheel slippage;
• and
• a differential gear control system for an automotive power train which includes:
• a differential gear unit disposed within a vehicular power train for distributing a driving torque to first and second driven wheels;
• a slip-limiting means, associated with said differential gear unit for adjusting a distribution ratio of drive torque for said first and second wheels, said slip-limiting means providing a variable distribution ratio of said driving torque according to a slip control signal value;
• a steering sensor monitoring steering behavior of a vehicular steering system to produce a sensor signal indicative of a steering direction and a magnitude of steering angular displacement;
• a differential gear control means receiving said steering angle signal for identifying first and second driven wheels relative to a curve, in which said first driven wheel is located inside with respect to the curve and said second wheel is located outside with respect to the curve, and producing said slip control signal for adjusting said distribution ratio to set a slip ratio of said second wheel at a given set value when a wheel speed at said first driven wheel is higher than that at said second wheel, and said control means being operatively connected with said traction control system and responsive to said wheel speed at said first wheel being higher than that at said second wheel to output a traction control disabling signal to said traction control system for disabling traction control.
