Abstract:
1. A drive state control apparatus for a vehicle comprising: a transfer (T/F) which includes an input shaft (A slippage determination means (Vfr, Vfl, Vrr, Vrl, Gx, ECU) for determining whether or not slippage occurs at the first and second left and right wheels; and control means (ECU) for switching the clutch mechanism from the decoupled state to the coupled state when at least one of the first left and right wheels is determined to have caused slippage in a state in which the clutch mechanism is in the decoupled state, wherein the control means is configured such that, when the vehicle is traveling and the clutch mechanism is in the coupled state, the control means executes an operation plural times in which operation the maximum transmittable torque is decreased from a present value by a first predetermined amount every time a predetermined condition is satisfied, and wherein in the case where the vehicle stops in a state in which the clutch mechanism is in the coupled state and the vehicle starts after that time, the control means maintains the maximum transmittable torque to be zero while the vehicle stops, and when the vehicle starts, the control means sets the maximum transmittable torque to a value which is obtained by subtracting, from a value of the maximum transmittable torque at the time of a previous start of the vehicle, a total decrease amount increased on a basis of the first predetermined amount in a period between the previous start of the vehicle and a present stoppage of the vehicle.
