    摘要： A vehicle 1 has a torque coupling 8, which is located in a driving power transmission system for transmitting the torque of an engine 2 to front and rear wheels 13f, 13r. The torque coupling 8 changes the torque distribution by adjusting the frictional engaging force of an electromagnetic clutch 16. The vehicle 1 also has a 4WD ECU 21 (CPU), which controls the operation of the torque coupling 8 based on the driving state. The 4WD ECU 21 (CPU) estimates a transfer case oil temperature Tptu. When the transfer case oil temperature Tptu is higher than or equal to a first predetermined transfer case oil temperature KTptu1, the 4WD ECU 21 executes overheat prevention control. When the deviation ΔA between an estimated vehicle acceleration Ae, which is computed based on a predetermined vehicle weight M and a driveline torque τd of the engine 2, and the actual vehicle acceleration Av is greater than or equal to a first predetermined deviation KΔA1, the 4WD ECU 21 (CPU) estimates the transfer case oil temperature Tptu to be higher. This allows the control mode of the torque coupling 8 to be smoothly switched to the overheat prevention control.

    摘要： When determining that a vehicle is not skidding, the ECU carries out tight corner control if vehicle speed is smaller than the upper limit value of the vehicle speed range corresponding to the starting state of the vehicle and the steering wheel turning angle of a steering wheel is greater than or equal to the minimum value of the steering wheel turning angle at which the tight corner braking phenomenon may occur. When determining that the vehicle is skidding, the ECU inhibits the tight corner control even if the vehicle speed is smaller than the upper limit value and the steering wheel turning angle is greater than or equal to the minimum value of the steering wheel turning angle at which the tight corner braking phenomenon may occur.

    摘要： A speed reducer is provided with a shock absorbing rubber damper disposed in a power transmission path from a first wheel to which a driving force of a motor is input to a second wheel from which the power is output. First projecting portions 3e and auxiliary projecting portions 3f are provided on a first wheel. Second projecting portions 5b are provided on a second wheel 5. The projecting portions are disposed together in intervals T defined between segmented rubber dampers 6. Receiver plates 7, 8 are attached to the end surfaces 6a, 6b of the rubber dampers 6 and serve as load bearing surfaces confronting the projections 3e, 3f and 5b so as to approximately distribute the loads over the entire end surfaces. Two receiver plates 7, 8 disposed across the end surfaces 6a, 6b can be arranged as an integral receiver plate unit U. With this arrangement, a shock absorbing capability is enhanced as well as the number of parts can be reduced.
