摘要： PROBLEM TO BE SOLVED: To prevent dragging torque due to the viscous resistance of hydraulic oil in a driving force transmission mechanism when releasing the engagement of a clutch 20c in a driving device for a vehicle which is equipped with the clutch 20c in the driving force transmission mechanism connecting a driving means 20a with a driving wheel 21b, releases the engagement of the clutch 20c when the driving means 20a is not in operation, and intercepts a connection state that the driving force is transmitted between the driving means 20a and a driving wheel 21b. SOLUTION: When the viscous resistance of the hydraulic oil in the case housing the driving force transmission mechanism is not less than a predetermined value at the time of releasing the joint of the clutch 20c, the viscous resistance of the hydraulic oil is reduced by reducing the viscous resistance of the hydraulic oil to below a predetermined value by driving the driving means 20a, and the generation of the dragging torque is prevented in the driving force transmission mechanism.

摘要： PROBLEM TO BE SOLVED: To suppress as small as possible the difference (gap) between a rotational speed calculated based on the frequency of a waveform signal and a rotational speed of an actual wheel at the point of time when detecting the edge of the waveform signal, not by calculating the rotational speed of the wheel at the point of time when detecting the edge of the waveform signal but by calculating the rotational speed of the wheel before reaching the point of time, when the rotational speed of the wheel becomes gradually low in a wheel speed device.
SOLUTION: When the present counter value N becomes larger than a signal frequency counter value Nn stored beforehand which is a counter value before reset in the case where the rotational speed of the wheel becomes gradually low (at the deceleration time of a vehicle), the CPU 21 of an electronic control device 20 calculates the rotational speed of the wheel based on the present counter value N at a fixed time (prescribed short time Δt) interval (step 128, 132).

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of torque exceeding an allowable value and resulting abnormal noise in a drive system, and an abrupt change in a vehicle behavior due to instantaneous switching between drive modes during the travel of a front and rear wheel drive vehicle.
SOLUTION: The control device selectively switch the drive mode of the vehicle between a two wheel drive mode and a four wheel drive mode by electrically controlling a driving force transmitter. Depending on a vehicle state at the time of a drive mode switching instruction, the control device prohibits switching control to an instructed drive mode when a traveling speed is low not higher than a prescribed value and the rotation difference between the front and the rear wheels is not lower than a prescribed value, and it executes gradual switching control gradually decreasing a driving force difference to a value not greater than a prescribed value when the traveling speed is middle or high not lower than the prescribed value, and the driving force difference between the front and the rear wheel sides before/after drive mode switching is not lower than a prescribed value.
