    • PROBLEM TO BE SOLVED: To evade damage to a transmission and rapid variation in a vehicle behavior by preventing rapid engagement of a transmission clutch that transmits power from an engine even when an abnormality occurs in an ignition power supply line during travel using power only from a motor while the transmission clutch is disengaged.SOLUTION: When it is detected that an ignition power supply line 17 has been cut off (that an ignition switch 18 has been switched OFF) during EV travel by disengaging a transmission clutch, a self-shut function is stopped while keeping a switching transistor Tr2 of a self-shut line 13b ON, and the transmission clutch is maintained in a disengaged condition by keeping a transmission clutch actuator 21 energized. Thus, the transmission clutch is not rapidly engaged, a sudden load from an engine 1 is not exerted on a drive system, rapid load variation is avoided, and the damage to the transmission and the rapid variation in the vehicle behavior are prevented.
    • 要解决的问题:为了避免变速器的损坏和车辆行为的快速变化,即使在行驶中使用动力时在点火电源线中发生异常,也能够防止从发动机传递动力的变速离合器的快速接合 只有当变速器离合器分离时才从电机。 解决方案:当通过分离变速器离合器检测到EV行驶期间点火电源线17已被切断(点火开关18已经断开)时,停止自动关闭功能,同时保持 自动关闭线路13b的开关晶体管Tr2导通,并且通过保持变速器离合器致动器21通电,变速器离合器保持在分离状态。 因此,变速离合器不能快速接合,不会对驱动系统施加来自发动机1的突然负荷,因此能够避免快速的负荷变动,防止对变速器的损坏和车辆行为的快速变化。 版权所有(C)2013,JPO&INPIT
