Title:
DIFFERENTIAL ROTATION RESTRICTION FORCE CONTROL DEVICE OF CENTER DIFFERENTIAL
Document Type and Number:
Japanese Patent JP2022188372
Kind Code:
A
Abstract:
To provide a differential rotation restriction force control device of a center differential having an increased lateral force which can be generated by a tire upon the turning.SOLUTION: A differential rotation restriction force control device of a center differential includes: a head-out state detection part 140 which is provided on a vehicle having a center differential 41 which transfers a driving force generated by a traveling power source 10 to a front wheel driving device 50 and a rear wheel driving device 60, and permits such differential rotations and a differential rotation restriction device 42 which restricts the differential rotations, and detects that the differential rotation restriction force control device of the center differential for controlling a restriction force of the differential rotation restriction device is in the turning state, and detects such a head-out state that the differential rotation restriction force control device of the center differential which controls the restriction force of the differential rotation restriction device is in the turning state and a yaw rate and a side slip angle get to the same sign; and a restriction force control part 120 which controls the restriction force so that a difference between a driving force of a front wheel by the output of the traveling power source and an absolute value of a braking force of the front wheel according to an internal part circulation torque of the center differential decreases in accordance with the detection of the head-out state.SELECTED DRAWING: Figure 4
