<p>PURPOSE:To simply make up a control device for a limited slip differential as well as to enhance responsiveness by generating signals which specify the upper and lower limits of a control target value, and thereby assuming feed-back control on the drive system of a vehicle by means of the add signal which is the sun of said signals. CONSTITUTION:In order to maintain the difference in revolution between front and rear wheels within specified values, a four-wheel drive vehicle makes a feed-back control means A assume feed-back control on the drive systom C of the vehicle in such a way that the difference in revolution between the front and rear wheels which is obtained based on the output from a vehicle speed detecting means B detecting the revolutions of the wheels, is maintained within specified values. A control device as described herein above is provided with an upper/lower limit signal generating means D which generates 2 signals specifying both of the upper and lower limits of a control target value in response to the running condition of the vehicle. In addition, the feed-back control means A is additionally provided with an add signal producing means E producing the add signal which is the sum of the aforesaid 2 signals generated by the generating means D so that the drive system C is thereby controlled based on the output from the producing means by means of feed-back operations.</p> |
