Abstract: In a state in which a vehicle travels while an internal-combustion-engine driving torque (Te) is transmitted to drive wheels, Te and a clutch torque Tc are decreased and an electric-motor driving torque (Tm) is increased based on the satisfaction of a shift-up condition (t1). Thereafter, based on the fact that Tc becomes zero (t2), a shift-up action is carried out while maintaining Tc to zero and maintaining a state in which Tm is transmitted to the drive wheels (t2 to t3). Then, based on the termination of the shift-up action (t3), Te and Tc are increased and Tm is decreased (t3 to t5). During the time period from the satisfaction of the shift-up condition to time at which Tc becomes zero (t1 to t2), a load torque (Ts) of a power generator rotationally driven by an output shaft of the internal combustion engine is generated.

Abstract: An on-demand-type drive state control apparatus for a vehicle is provided. In the case where acceleration slippage occurs at drive wheels (rear wheels) of a vehicle when a drive system is in a two-wheel drive state, the drive system is switched from the two-wheel drive state to a four-wheel drive state. That is, the maximum transmittable torque of a multi-disc clutch mechanism increases from “0” to a predetermined value. In the four-wheel drive state, the maximum transmittable torque decreases stepwise from the present value by a predetermined value every time the vehicle travels over a predetermined distance in a state in which none of the wheels cause acceleration slippages. That is the clutch drive current supplied to the multi-disc clutch mechanism decreases gradually (stepwise or in a plurality of steps), and the drive torque distributed to the front wheels (rear wheels) decreases (increases) gradually.

Abstract: A drive state control apparatus is applied to a vehicle which has not only a transfer including a multi-disc clutch mechanism but also a changeover mechanism interposed in an axle and which can be switched between 2WD and 4WD. When a 2WD-to-4WD changeover condition is satisfied, the multi-disc clutch is immediately switched from a “decoupled state” to a “coupled state.” Meanwhile, a connecting operation of the changeover mechanism is started upon establishment of a state in which left and right rear wheels have no acceleration slippage, and a state in which rotational speeds of first and second axles on opposite sides of the changeover mechanism are approximately equal to each other. In addition, in the case where the left and right rear wheels have acceleration slippage after the 2WD-to-4WD changeover condition has been satisfied, an E/G output reduction control is executed. Thus, the connecting operation can be performed smoothly.

A stator has paired inner cores configured by two inner cores facing back to back and each having a disk part and pole teeth. Each of the disk parts is provided with a terminal block holding part. The terminal block is connected with the terminal block holding parts via a resin connection part that is insert molded. The terminal block holding parts are provided with recesses configured by cutouts in portions to face the terminal block, respectively. The resin connection part has a thickness increased by filling the recesses so as to increase the strength at a connection portion thereof. The cutouts in the terminal block holding parts facing back to back are offset with respect to a radial line, terminal block facing ends are generally spaced apart from the terminal block by a constant distance. Therefore, the terminal block is prevented from being unstable.
