    • A control device is provided for electrically controlling a drive power transmission device arranged on a driving power transmission path of a front-and rear wheel drive vehicle thereby to switch the drive mode of the vehicle selectively to either of a two-wheel drive mode and a four-wheel drive mode. The control device inhibits the drive mode from being switched to that commanded to be switched to when the vehicle is traveling at a slower speed than a predetermined speed and when the rotational speed difference between front and rear wheels is larger than a predetermined value. Further, the control device gradually decreases a present torque which the driving power transmission device is transmitting before the switching of the drive mode, to a target torque which the drive power transmission device is to transmit after the switching of the drive mode, when the difference between the present and target torques is more than another predetermined valve at the time of the switching of the drive mode. Thus, the driving power transmission path can be prevented from generating the drive torque beyond a tolerable valve as well as making a noise due to the instantaneous switching of the drive mode during the traveling of the vehicle, and the vehicle can be prevented from abruptly changing its motion by the cause of the instantaneous drive mode switching.
    • 提供一种控制装置,用于电动控制布置在前后驱动车辆的驱动动力传递路径上的驱动力传递装置,从而选择性地将车辆的驱动模式切换到两轮驱动模式和 四轮驱动模式。 当车辆以比预定速度慢的行驶速度以及前轮和后轮之间的转速差大于预定值时,控制装置禁止驱动模式切换到命令切换到的方式。 此外,当驱动模式切换时,控制装置将驱动动力传递装置正在传送的当前扭矩逐渐降低到在驱动模式切换之后驱动动力传递装置将要传送的目标扭矩,当差异 当前和目标转矩之间在驱动模式切换时多于另一预定阀。 因此,可以防止驱动力传递路径产生超过容许阀的驱动转矩,并且由于在车辆行驶期间的驱动模式的瞬时切换而产生噪声,并且可以防止车辆突然改变 其运动原因是瞬时驱动模式切换。

    • A torque distribution control device for a four-wheel drive vehicle is disclosed, wherein a torque transmitted from an engine to prime drive wheels is distributed by an electromagnetic clutch to sub-drive wheels on an on-demand basis. A pre-torque is determined based on a vehicle speed and a throttle opening degree in a feed-forward sense. A compensation torque is determined based on the rotational speed difference between the prime drive wheels and the sub-drive wheels and the vehicle speed in a feedback sense. The pre-torque and the compensation torque are added for a command torque, depending on which the electromagnetic clutch is controlled to transmit the torque from the engine to the sub-drive wheels. At this time, since the command torque is limited to an upper limit value therefor or below in dependence on the engine torque, an ECU can be prevented from applying an excess current to an electromagnetic coil of the electromagnetic clutch and hence, from generating heat to raise its temperature when the engine torque is small.
    • 公开了一种用于四轮驱动车辆的扭矩分配控制装置,其中从发动机传递到主驱动轮的扭矩由电磁离合器按照需要分配到副驱动轮。 基于车辆速度和前馈方向的节气门开度来确定预转矩。 基于主驱动轮和副驱动轮之间的转速差和反馈意义上的车速确定补偿转矩。 根据控制电磁离合器将扭矩从发动机传递到副驱动轮,将预扭矩和补偿扭矩加到指令转矩上。 此时,由于根据发动机转矩将指令转矩限制在上限值以下,所以能够防止ECU向电磁离合器的电磁线圈施加过大的电流,因此不产生热量 当发动机扭矩小时,提高其温度。
