    摘要: In a steering system 30, a transmission ratio R1 which is determined in dependence on the vehicle speed by reference to a transmission ratio decision map is multiplied with a first transmission ratio alteration gain g10 which is determined in dependence on the distribution of a traveling drive torque from an engine 11 to front wheels 14 and rear wheels 15, thereby to alter the ratio R1 of steering torque distribution from a steering handle 31 to the front wheels 14, whereby the variation of the steering feeling due to an increase or decrease in the distribution of the traveling drive torque to the front wheels 14 can be suppressed. Further, the transmission ratio R1 is multiplied with a second transmission ratio alteration gain g11 which is determined in dependence on the gradient of the road surface by reference to a second transmission ratio alteration map, thereby to alter the transmission ratio R1, whereby the variation of the steering feeling due to the variation of the gradient can also be suppressed.

    摘要: A CPU computes a throttle opening degree increasing speed Vθh and a steering wheel angular velocity Vθ based on a throttle opening degree θh and a steering wheel angle θ. Based on the throttle increasing speed Vθh and the steering wheel angular velocity Vθ, the CPU selects one of a first drive mode and a second drive mode. The CPU controls the power transmission ratio of a power transmitting device according to the selected drive mode. Therefore, the power transmission ratio of the power transmitting device is properly controlled in accordance with the degree of intention for acceleration of the driver, which is computed based on the throttle increasing speed Vθh, and the turning speed of the steering wheel, which is computed based on the steering wheel angular velocity Vθ. Therefore, the drive mode is properly switched in accordance with the driving state of a four-wheel drive vehicle.

    摘要: A drive system control method and a drive power transmission control system for a four-wheel drive vehicle are provided for enabling the vehicle to operate selectively in an ordinary mode and an anti-vibration mode. In the ordinary mode, the connection force of a coupling device which is provided between front and rear wheel torque transmission axles is kept relatively high, and the front and rear wheel torque transmission axles are brought to connect prime drive wheels with secondary drive wheels, so that four-wheel drive traveling of the vehicle can be realized. The operation mode of the vehicle is switched from the ordinary mode to the anti-vibration mode where the secondary drive wheels slip when the vehicle begins to start in the ordinary mode. In the anti-vibration mode, the connection force of the coupling device is relatively weakened to substantially separate the front and rear wheel torque transmission axles from each other. Thus, the resilient force produced by the torsion of the front and rear wheel torque transmission axles which is caused by the slip of the prime drive wheels or the secondary drive wheels is released between the front and rear wheel torque transmission axles, so that the vibration which would otherwise be generated when the vehicle performs the four-wheel drive starting can be suppressed compared with that in the prior art.
