Control apparatus for limited-slip differential for front and rear wheels of vehicle
First Claim
1. A control apparatus for a limited-slip differential for front and rear wheels of a vehicle, the control apparatus comprising:
- a basic LSD torque calculation module configured to calculate a basic LSD torque at least on a basis of a transfer input torque;
a subtraction LSD torque calculation module configured to calculate a subtraction LSD torque that is subtracted from the basic LSD torque at least on a basis of a vehicle speed and a steering angle;
a minimum LSD torque calculation module configured to calculate a minimum LSD torque on the basis of the transfer input torque;
a target LSD torque setting module configured to set a target LSD torque at least on a basis of the basic LSD torque, the subtraction LSD torque, and the minimum LSD torque; and
a clutch control module configured to control an engaging force of a clutch configured to freely limit a differential of the front and rear wheels in accordance with the engaging force on a basis of the target LSD torque.
